Decisions to forgo life support may depend heavily on the icu where patients are treated

May 21, 2013 ? The decision to limit life support in patients in the intensive care unit (ICU) appears to be significantly influenced by physician practices and/or the culture of the hospital, suggests new findings from researchers at the Perelman School of Medicine at the University of Pennsylvania presented at the American Thoracic Society International Conference on May 21.

A retrospective analysis of over 269,000 ICU patients from the Project IMPACT database revealed a substantial variation in decisions to forgo life-sustaining therapies rates among 153 ICUs in the United States -- which suggests many factors unrelated to the patient or family may be affecting such decisions, particularly for patients who are unable to participate in decision making.

"Patient factors such as severity of illness, age, race, and functional status explain a significant amount of the variability in decisions to forgo life-sustaining therapies, but it is likely that ICU culture and physician practices also play a major role," said Caroline M. Quill, MD, a fellow in the department of Pulmonary, Allergy, and Critical Care at Penn Medicine. "My sense is because patients in the ICU are often unable to participate in decision-making, the influence of providers and the ICU culture may be even greater than the patient or family preference."

One in five Americans die during or shortly after an ICU stay, with many them dying following a decision to forgo life support. Though these decisions are common, the influences on these decisions are not well understood.

Limitations on care include do-not-resuscitate orders, withholding or withdrawing mechanical ventilation, withholding CPR, or an order for comfort measures or hospice care.

In order to study better understand these influences, the researchers wanted to quantify the variation among ICUs after adjusting for patient factors -- gender, condition, age, and race, for example. The thought is that if a host of patient characteristics can be identified that reliably predict who will and who will not have a decision to forgo life-sustaining therapy, then after adjustment for such characteristics among large samples of ICU patients, rates should be relatively consistent among ICUs.

Here, that was not the case. Overall, 11.7 percent of patients had a decision to forgo life-sustaining therapies among 153 ICUs in the US between 2001 and 2009. Of those, 58.8 percent died in the ICU and 41.2 percent survived to ICU discharge. After researchers adjusted for patient factors in their model, the study still revealed a six-fold variation among ICUs in the probability of a decision to forgo life-sustaining therapy. This suggests that the ICU to which a given patient is admitted influences his or her odds of having a DFLST, regardless of personal or clinical characteristics.

The team also looked at which patient characteristics are associated with these decisions. Older patients, women, and patients with more functional limitations at the time of admission to an ICU were more likely to limit life support, the researchers found. Conversely, black race and other non-white races were less likely to make the decisions to forgo life-sustaining therapies.

"This high variability among ICUs highlights an opportunity to improve upon 'patient-centeredness' in end of life decisions," said Dr. Quill. "Knowing how certain physicians reach and convey prognostic judgments, and how an ICU culture, their organizational factors, like nighttime staffing, influences these decision may help us devise targeted interventions to improve the quality of end-of-life care."

Sarah J. Ratcliffe, PhD, Michael O. Harhay, MPH and Scott D. Halpern, MD, PhD are co-authors on the study.

Kepler epitaph? Eight most intriguing finds of troubled telescope.

Kepler, the space telescope designed to help us find other Earth-like planets, is on the fritz. Scientists hope they will be able to fix it remotely, but if they can't, its brief, brilliant career could be over. Since it began operations in 2009, peering continuously at the same field of 145,000 stars in the constellations Cygnus and Lyra, it has found more than 2,700 planet-candidates. Here are eight of its most remarkable discoveries.?

1. Kepler-22b: Goldilocks planet

Kepler has made an array of stunning discoveries ? from oddball solar systems to sun-scorched planets that orbit their stars in less than an Earth day. But Kepler-22b was the first discovery that truly validated the mission.

The goal for Kepler has always been to find Earth-mass planets orbiting sun-like stars at Earth-like distances. In other words, to find Earth's cosmic twins. Kepler-22b was perhaps a bit more like a big brother ? it's larger than Earth ? but its discovery was proof that Kepler was on the right track.

Scientists announced the discovery of Kepler-22b in December 2011. It was smack dab in the middle of its star's so-called habitable zone ? the "Goldilocks zone" close enough to allow water to be liquid but far enough to ensure that it didn't burn off. Kepler-22b orbits its sun once every 290 days. Moreover, its sun is the same G-type star as our sun, though slightly smaller and cooler.

The planet itself has a radius 2.4 times larger than Earth. Scientists are not sure about the composition of the planet, but some have suggested it could be a mini-Neptune with a global ocean and a rocky core. If it has an atmosphere, the temperature could be 72 degrees F.

"It's so exciting to imagine the possibilities," Natalie Batalha, the Kepler deputy science chief, told the Associated Press in 2011. Floating on that "world completely covered in water" could be like being on an Earth ocean, and "it's not beyond the realm of possibility that life could exist in such an ocean."

The Reference Frame: Anthony Zee: Einstein Gravity in a Nutshell

?koda is not just a carmaker; it is producing happy drivers. And you may see that even the engines in the factory are having a great time.

In the same way, Anthony Zee ? as Zvi Bern noticed ? decided to make many readers fall in love with the physics of general relativity by having written this wonderful tome, Einstein Gravity in a Nutshell. Bern said that the goal wasn't to create new experts but Zee corrected him that he wanted to make the readers fall in love so deeply that they may dream about becoming experts, too. And the clearly enthusiastic Anthony had to enjoy the writing of the book, too.

I received this large, almost 900-page scripture on Einstein's theory yesterday. Obviously, I haven't read the whole book yet but I may have spent more time with it than most readers (more than zero) so that I can tell you why you should buy it and what philosophy, style, and content you may expect.

It's a book addressed to a wide variety of readers, including very young ones (perhaps college freshmen and bright high school students) and amateur physicists. Experienced physicists and professionals may find some gems or at least entertainment in the book, too. Because of this goal, the book starts with elementary things such as the units including \(G,c,\hbar\) and Planck units, relativity even in classical physics, as well as basics of curved spaces, differential geometry, and so on.

The style is witty and somewhat dominated by words ? and amusing titles. You may find lots of philosophical and historical remarks and stories from Anthony's professional life but the physics is always primary. And I mean physics, not rigorous mathematics. Tony is focusing on objects, phenomena, and their measurable and calculable quantities and the purpose of physics is to understand them and calculate them. So he spends almost no time with various picky issues ? whether a function has to be smooth; whether one should use one fancy word from abstract mathematics or another. In fact, he considers the suppressed role of rigorous maths to be a part of the "shut up and calculate" paradigm that he subscribes to.

In some sense, you could say that the approach resembles the Feynman Lectures on Physics. It is very playful and the author is always careful to tell you think that are still fun and stop elaborating on details when he could start to bore you. So the book (probably) keeps its fun status at every place (it's true for the portions I have read). But Anthony Zee manages to penetrate much more deeply into general relativity with this strategy.

Once he goes through all the basics ? which allow a beginner to start with the subject almost from scratch but which seem very entertaining for a reader who doesn't really need such introductions anymore ? and he answers all the FAQs on tensors and lots of other things, he offers some of the simplest derivations of Einstein's equations and is ready to apply them.

It's useful to know what concepts are considered primary starting points by the author. I would say that Zee is elevating the concept of symmetries and the action ? the latter allows us to formulate most dynamical laws in classical and quantum physics really concisely (although we know perfectly consistent quantum systems that don't seem to have any nice action; and the action always assumes that we prefer a particular classical limit of a quantum theory ? and the classical limit isn't necessarily unique).

Concerning the applications, some of the historically important applications that were designed to verify the theory are suppressed. But you get very close to the cutting edge, including the general-relativistic aspects of topics that are hot in the contemporary high-energy theoretical physics and the cosmological/particle-physics interface. So you may actually learn advanced topics about black holes including some Hawking radiation (including the numerical prefactors of the temperature; but the author doesn't go extremely far here; note that amusingly enough, the Hawking radiation is even discussed in an introductory chapter); large and warped extra dimensions; de Sitter and anti de Sitter space including a discussion of conformal transformations (although it doesn't seem like a full-fledged textbook on AdS/CFT); topological field theories; Kaluza-Klein theory (with extra spatial dimensions) and braneworlds; Yang-Mills theory (there's lots of electromagnetism in the earlier chapters); even twistor theory; discussions on the cosmic inflation and the cosmological constant problem; and heuristic thoughts on quantum gravity (some of them are more heuristic than the state-of-the-art allows us; but Zee's philosophy is that textbook shouldn't be composed exclusively of the totally established stuff ready to be carved in stone).

Using lots of witticisms and clever analogies, Zee also proves some things you wouldn't expect ? e.g. that Hades isn't inside the Earth. The equivalence principle is compared to the decision of all airlines, regardless of the size (and the size of their aircraft), to fly between two distant cities along the same path on the map. Witty and apt.

Anthony is convinced that most authors are explaining things in unnecessarily complicated ways ? in some cases, perhaps, they want to look smart by looking incomprehensible. That's not Zee's cup of tea. He enjoys to simplify things as much as possible (but not more than that). And he loves to formulate things so that the reader is led to the conclusion that things are simple and make sense, after all. For example, there is a fun introduction to the least action principle (light isn't stupid enough not to know the best path) and we learn that "after Lagrange invented the Lagrangian, Hamilton invented the Hamiltonian". It makes sense, doesn't it?

There's a lot to find in the book. Some readers say that the book is less elementary than Hartle's book but more elementary than Carroll's. Maybe. Anthony is more playful and less formal but there are aspects in which he gets further than any other introductory textbook of GR.

The book is full of notes, a long index, and simply clever exercises. The illustrations are pretty and professional. If you are buying books to see photographs of attractive blonde women with toys, you won't be disappointed, either.

Because the book is really extensive and even the impressions it has made on your humble correspondent in the single day are numerous, I have to resist the temptation to offer you examples, excerpts etc. because that could make this blog entry really long by itself. Instead, I recommend you once again to try the book.

NBC hires news division chief from Britain

(AP) ? NBC went out of the company and out of the country to find a president for its news division, on Monday naming the first woman to hold the top job.

Deborah Turness, former editor of ITV News in Britain, replaces Steve Capus, who resigned earlier this year, and will begin her new job in August.

Turness will take over a news division bruised by the "Today" show losing its long-held dominant position in the morning to ABC's "Good Morning America." NBC's flagship "Nightly News" broadcast still tops the evening news ratings, but anchor Brian Williams recently saw his "Rock Center" newsmagazine abruptly canceled after less than two years on the air.

"It is quite simply the greatest imaginable honor to be named as the next president of NBC News," Turness said.

In NBC's new management structure, she reports to Pat Fili-Krushel, head of the NBC Universal News Group, as do MSNBC President Phil Griffin and CNBC President Mark Hoffman.

Fili-Krushel was not immediately available for comment. She said in a statement that Turness is "very familiar" with NBC News through a partnership the two networks have.

Turness, who is 46, became editor of ITV News in 2004, the first woman and youngest person to hold that job. Often overshadowed by the state-funded BBC, ITV is Britain's largest commercial television network. ITN, which is 40 percent owned by ITV, is Britain's top commercial news producer. Turness joined the company in 1988 as a news producer and worked for four years during the 1990s in the company's Washington bureau.

"Deborah epitomizes everything that is best about ITN, inspiring our newsrooms with her ideas, enthusiasm and energy," said John Hardie, CEO of ITN. As editor of ITV News, Turness was in charge of news coverage and business operations.

The morning will no doubt be her top priority upon joining NBC. The decline of "Today" is a major blow to the company's pride and bottom line. Women dominate the show's viewership and the ham-fisted replacement of anchor Ann Curry with Savannah Guthrie last year tore at the show's popularity. It has not gone unnoticed that men supervised the show during its turnover.

Within the next two years, Turness will likely be responsible for choosing Matt Lauer's successor on "Today" should the long-running anchor decide to leave.

"Nightly News" still has a comfortable lead in evening news ratings over ABC and CBS. But Turness will probably face lingering morale issues related to the cancellation of "Rock Center" after being bounced around the network's prime-time schedule.

Earth's iron core is surprisingly weak

May 20, 2013 ? Researchers have used a diamond anvil cell to squeeze iron at pressures as high as 3 million times that felt at sea level to recreate conditions at the center of Earth. The findings could refine theories of how the planet and its core evolved.

Through laboratory experiments, postdoctoral researcher Arianna Gleason, left, and Wendy Mao, an assistant professor of geological and environmental sciences and of photon science, determined that the iron in Earth's inner core is about 40 percent as strong as previously believed.

The massive ball of iron sitting at the center of Earth is not quite as "rock-solid" as has been thought, say two Stanford mineral physicists. By conducting experiments that simulate the immense pressures deep in the planet's interior, the researchers determined that iron in Earth's inner core is only about 40 percent as strong as previous studies estimated.

This is the first time scientists have been able to experimentally measure the effect of such intense pressure -- as high as 3 million times the pressure Earth's atmosphere exerts at sea level -- in a laboratory. A paper presenting the results of their study is available online in Nature Geoscience.

"The strength of iron under these extreme pressures is startlingly weak," said Arianna Gleason, a postdoctoral researcher in the department of Geological and Environmental Sciences, and lead author of the paper. Wendy Mao, an assistant professor in the department, is the co-author.

"This strength measurement can help us understand how the core deforms over long time scales, which influences how we think about Earth's evolution and planetary evolution in general," Gleason said.

Until now, almost all of what is known about Earth's inner core came from studies tracking seismic waves as they travel from the surface of the planet through the interior. Those studies have shown that the travel time through the inner core isn't the same in every direction, indicating that the inner core itself is not uniform. Over time and subjected to great pressure, the core has developed a sort of fabric as grains of iron elongate and align lengthwise in parallel formations.

The ease and speed with which iron grains in the inner core can deform and align would have influenced the evolution of the early Earth and development of the geomagnetic field. The field is generated by the circulation of liquid iron in the outer core around the solid inner core and shields Earth from the full intensity of solar radiation. Without the geomagnetic field, life -- at least as we know it -- would not be possible on Earth.

"The development of the inner core would certainly have some effect on the geomagnetic field, but just what effect and the magnitude of the effect, we can't say," said Mao. "That is very speculative."

Gleason and Mao conducted their experiments using a diamond anvil cell -- a device that can exert immense pressure on tiny samples clenched between two diamonds. They subjected minute amounts of pure iron to pressures between 200 and 300 gigapascals (equivalent to the pressure of 2 million to 3 million Earth atmospheres). Previous experimental studies were conducted in the range of only 10 gigapascals.

"We really pushed the limit here in terms of experimental conditions," Gleason said. "Pioneering advancements in pressure-generation techniques and improvements in detector sensitivity, for example, used at large X-ray synchrotron facilities, such as Argonne National Lab, have allowed us to make these new measurements."

In addition to intense pressures, the inner core also has extreme temperatures. The boundary between the inner and outer core has temperatures comparable to the surface of the sun. Simultaneously simulating both the pressure and temperature at the inner core isn't yet possible in the laboratory, though Gleason and Mao are working on that for future studies. (For this study, Gleason mathematically extrapolated from their pressure data to factor in the effect of temperature.)

Gleason and Mao expect their findings will help other researchers set more realistic variables for conducting their own experiments.

"People modeling the inner core haven't had many experimental constraints, because it's so difficult to make measurements under those conditions," Mao said. "There really weren't constraints on how strong the core was, so this is really a fundamental new constraint."

MEBAA to host inaugural Middle East Business Aviation Conference ...

The conference will be held under the patronage of H.H. Prince Fahd bin Abdulla bin Muhammad, President of General Authority of Civil Aviation (GACA).

At the conference, set to take place on 4th June 2013 at the Hilton Hotel in Jeddah, MEBAA has gathered some of the most prominent leaders of the region's aviation sector to discuss the issues affecting the Kingdom's business aviation market.

The Kingdom is experiencing huge growth in the sectorand is widely recognised as one the biggest markets in the GCC commanding at least 35% of the market share. The MENA market is earmarked to continue its growthas was showcased by Honeywell Aerospace at MEBAC 2012 in Dubai. Honeywell have forecasted 14,000 business aircrafts deliveries through to 2017, generating industry sales of $233 billion (DH856 billion), with the Saudi Arabian market expected to be one of the main contributors to this growth.

Talking about the Saudi Arabian market, Mr Wajdi Alidrissi, Managing Director of Saudi Private Aviation (SPA), sponsor of the conference said, "We anticipate that the Saudi Arabian market will witness growth of atleast 10% through to 2014, due to the government's bold plans for economic cities across the Kingdom and other major infrastructure projects currently underway and in the pipeline,"

The conference will take the form of keynote speeches in the morning delivered by H.H. Prince Fahd bin Abdulla bin Muhammad, President of GACA, H.E. Dr. Faisal Bin Hamad Al Sughair Vice President of GACA and Mr Wajdi Alidrissi, Managing Director of Saudi Private Aviation. In the afternoon, the conference will move into panel discussions where CEOs and Directors of some of the most prominent companies in the industry and regulatory authorities will debate important topics such as the grey market and regulatory frameworks. Such companies include GACA, GCAA, NasJet, Nexus and SPA to name a few.

Speaking about MEBAC, Mr Ali Ahmed Al Naqbi, Founding Chairman of MEBAA said,"We are continuing to see a healthy growth of the Kingdom's business aviation industry. With such growth must come continual dialogue with industry stakeholders ensuring that the interests of business aviation are promoted and protected. Through MEBAC, we aim to deliver a platform to share our concerns and promote business aviation within the economic agenda of the Kingdom of Saudi Arabia.

Through conferences like MEBAC, MEBAA ensures that it continues to act as the principle forum for gathering, understanding and communicating the needs of the business aviation community within the Middle East and North Africa to businesses, government and worldwide media".

Hood County Sheriff Roger Deeds said Friday that all missing people are accounted for, and the death toll is unlikely to rise above six adults.

Surveying the extensive destruction in Granbury, Texas, residents and volunteers say they are surprised that more people were not killed or seriously injured.

?The good Lord was busy [Wednesday] night,? Red Cross volunteer Ray Fishercord told the Fort Worth Star-Telegram.?

?Most of the homes had people in them when the tornado hit, and most of the people said they couldn?t believe what happened. The American Legion Hall at the bottom of the hill looked like a triage scene from 'M*A*S*H.' ?

An EF-4 category tornado hit Granbury, carrying winds of 166 to 200 m.p.h. and creating a path of destruction spanning 100 yards wide and a mile long. The highest tornado rating is an EF-5, which produces winds faster than 200 m.p.h.

Residents in the Rancho Brazos neighborhood ? where more than 70 homes were damaged or destroyed ? were evacuated, and authorities said it not clear when they will be able to survey the damage.

"I can't see them being able to get anyone in the area," said Hood County sheriff's spokesman Nathan Stringer. "That area is utterly devastated. I was in there for a couple of hours and I didn't see anything untouched. It was one big debris field."

Amanda Hernandez was at home with her husband and three children, but the warnings on TV didn?t really worry her. The sirens went off about 15 minutes before the tornado hit, so the family hid in a closet.

?It seemed like it lasted for an hour,? she told the Star-Telegram, describing the pounding hail and train-like sound of the twister. Her house lost half its roof, and she said her neighborhood is unrecognizable.

?You could see across where houses were supposed to be,? Ms. Hernandez said.

The Granbury tornado was one of at least 16 confirmed tornadoes that broke out across north Texas Wednesday, which is more than the 10 originally reported.

An EF-3 tornado (with winds ranging from 136 to 164 m.p.h.) hit the town of Cleburne, destroying numerous homes, but officials reported no major injuries or fatalities.

Meteorologist Harold Brooks, who works at National Severe Storms Labratory in Norman, Okla., said he expects 2013 to have one of the lowest levels of tornado-related deaths since the lab began tracking such fatalities in 1954. This is the furthest into tornado season that significant tornadoes have started, he told the Star-Telegram.

The forecast, however, includes a chance for additional storms in the area this weekend, the Weather Channel reports. There are several components in the mix that create tornado conditions: a dip in the jet stream as it moves east from the Rockies, intensifying low-pressure systems, and warm moisture moving inland from the Gulf of Mexico.

Thunderstorms, hail storms, and potential tornadoes are possible for Oklahoma, the Dakotas, Missouri, Nebraska, and parts of northern Texas throughout the weekend and possibly into Tuesday.

Mystery of moon's magnetic field deepens

The moon generated a surprisingly intense magnetic field until at least 3.56 billion years ago, 160 million years longer than previously thought, a new study reports.

These findings could shed light not just on the magnetic field of the moon, which is now extremely weak, but on that of asteroids and other distant worlds, investigators added.

Earth's magnetic field is created by its internal dynamo, which itself is generated by the planet's churning molten metal core. Research increasingly suggests that the moon once had a dynamo as well, with evidence of magnetism found in lunar rocks returned by Apollo astronauts. [10 Surprising Moon Facts]

Models of the moon's core suggest its dynamo should have lasted only until about 4.1 billion years ago. However, last year, scientists revealed that the moon possessed a magnetic field for much longer than previously thought, with a powerful dynamo in its core from 4.2 billion years ago to at least 3.72 billion years ago.

Researchers have proposed two possibilities to explain why the moon's dynamo lasted so long. One possible explanation is that giant cosmic impacts set the moon lurching enough to drive its dynamo. Another explanation has to do with how the moon's core spins around a slightly different axis than its surrounding mantle layer, generating wobbles ? known as precession ? that could dramatically stir its core.

The cosmic-impact idea is supported by the fact that the moon experienced massive collisions until around 3.7 billion years ago, such as the one that created the 715-mile-wide (1,150 kilometers) Mare Imbrium, among other craters.

However, the dynamo generated by each impact would have lasted for a mere 10,000 years or so, scientists say. In contrast, if precession drove a lunar dynamo, the moon could have continuously possessed a magnetic field until as late as 1.8 billion years ago.

Now, a new analysis of the biggest lunar rock brought back to Earth by Apollo 11 astronauts in 1969 reveals the moon's dynamo lasted about 160 million years longer than previously thought, well after the last of the largest crater-forming impacts hit the moon.

Scientists investigated a 5-gram (0.18 ounces) sample taken from a 3.56-billion-year-old volcanic moon rock from the Sea of Tranquility.

"When rocks solidify from a lava, they capture a record of the magnetic field in their environment," said study lead author Cl?ment Suavet, a geoscientist at MIT. "By studying rocks of different ages, we can reconstruct the history of lunar-surface magnetic fields."

The analysis revealed the intensity of the lunar magnetic field was exceptionally strong 3.56 billion years ago, "almost identical to the field measured in a previous study of 3.7-billion-year-old rocks," Suavet told SPACE.com. "This seems to indicate that the lunar magnetic field was remarkably stable."

The ancient magnetic field of the moon was about as intense as Earth's current surface magnetic field. This makes it about 1,000 times stronger than the moon's present surface magnetic field, researchers said.

Learning more about how the moon's dynamo originated and developed could yield insights into the dynamos of smaller objects, such as asteroids, and larger bodies, such as planets.

"The moon is like a giant laboratory where we can test our theories about how planets form and evolve," Suavet said.

Many questions remain about the moon's magnetic field, such as why it was so intense late into lunar history and how it disappeared over time.

After IRS scandal: Right-wing fear of government isn't paranoid

Whatever the motivations for the IRS targeting conservative groups, it has drawn condemnation from across the political spectrum. Liberals also worry the scandal will feed right-wing paranoia of government.?But for conservatives, fear of federal agencies is rooted in history, not hysteria.

By Nicole Hemmer,?Op-ed contributor / May 17, 2013

Ousted IRS chief Steven Miller testifies on Capitol Hill, May 17, before the House Ways and Means Committee hearing on the extra scrutiny the IRS gave tea party and other conservative groups that applied for tax-exempt status. Op-ed contributor Nicole Hemmer writes: '[A]s conservatives (as well as many on the left) have been constantly reminded...power is never neutral.'

Last week?s revelation that the Internal Revenue Service targeted conservative groups was met with near universal disapproval. The IRS singled out organizations with words like "tea party" and "patriot" in their name for scrutiny. In the words of Treasury officials, this focus was clearly ?inappropriate.?

What?s less clear is whether the IRS?s motivations were partisan or practical. Were they deliberately trying to stifle conservative voices? Or were they simply using a shortcut to weed out new political groups who don?t meet tax-exempt status??Whatever the motivations, the results have drawn condemnation from across the political spectrum. But criticisms from the left have also been tinged with concern about how the episode would bolster the conservative argument against big government.

Many liberals worried the IRS scandal would feed what one Democratic aide called ?the right-wing paranoia that the government is out to get them.??MSNBC host Chris Matthews grumbled recently, "They always expect the worst." But for conservatives, fear of federal agencies is rooted in history, not hysteria.

Fifty years ago this month, journalists Donald Janson and Bernard Eismann published ?The Far Right,? a catalogue of conservative organizations across America.?Raising the alarm about the coming conservative threat was something of a cottage industry in the early 1960s. ?The Far Right? would share shelf-space with books like ?The Radical Right? and ?Danger on the Right.? But what separated ?The Far Right? from the rest was its revelation of the Reuther Memorandum.

Commissioned by Attorney General Robert Kennedy and penned by labor leader Victor Reuther, the 24-page memo detailed ?possible Administration policies and programs to combat the radical right.?

Reuther defined the ?radical right? as ?bounded on the left by Senator Goldwater and on the right by [John Birch Society founder] Robert Welch.? And he suggested plenty of ways for the government to curtail the right?s influence, from putting conservatives on the attorney general?s subversive list to using the Federal Communications Commission to limit their airtime.

But the administration?s real power, Reuther argued, lay with the IRS. Conservative media and organizations needed money to function. Therefore, ?action to dam up these funds may be the quickest way to turn the tide? against right-wing groups.

He called for revocation of organizations? tax-exempt status, a tactic similar to the approach which the IRS is currently under fire for possibly employing. Reuther also suggested the IRS investigate corporations that advertised in right-wing media, contending they were peddling propaganda rather than selling products.

Finally, Reuther hinted conservative donors and media personalities should be audited, noting ?there is the big question whether [they] are themselves complying with the tax laws.?

While it is unclear whether the memo served as the basis for policy, during the Kennedy administration the IRS cracked down on ?ideological organizations? and the FCC targeted conservative broadcasters.

What?s the Matter With Portland?

Glass filled with drinking water from kitchen faucet. As of 2010, almost three-quarters of Americans drink fluoridated water from community water systems

Photo by Juri Samsonov/Think Stock

America is a fluoride nation. Beginning in 1945, when Grand Rapids, Mich., became the first city in the world to add the stuff to its water supply, the practice has spread across the United States. In most areas it is simply understood that ingesting minuscule levels of fluoride is good for dental health. As of 2010, almost three-quarters of Americans drink fluoridated water from community water systems, and the nation?s 30 most populous cities consume it.

With one weird exception: Portland, Ore., whose water system, sourced from the Bull Run River, serves 900,000 people.

A fluoridation proposal was put up for a popular vote in 1956, when many major metropolitan areas were adopting the practice, but it failed by a sizeable margin: 105,191 to 75,354. A similar attempt in 1962 failed, too. The late 1970s saw a flurry of activity, long after the issue had faded from the national political discourse. Oregon voters killed a statewide ballot initiative that would have banned fluoride (1976); Portlanders voted to add fluoride to the water (1978); and then they reversed course and voted to keep it out of the water supply (1980).

The fluoridation debate remained dormant until last summer, when someone leaked to the Oregonian that a coalition was quietly pushing the City Council to simply approve fluoridation without relying on a ballot measure. Less than a month later, the council unanimously did just that by enacting Ordinance 185612, which required the Water Bureau to add fluoride at 0.7 parts per million beginning in March, 2014. Atlantic Cities? Nate Berg wrote approvingly at the time, ?resistance from one of the country's biggest cities may be coming to an end.?

Resistance was just beginning. The banners of dissent were quickly raised. A public hearing on the ordinance lasted for almost seven hours, and almost all of the speaking time was taken by people against fluoridation. When the council voted the motion through, protesters booed loudly, vowing to bring the matter before the public. (Several of the more boisterous activists were expelled from the chamber.) Within a month more than 43,000 signatures were collected, more than twice the number needed to bring the issue to a popular vote.

?The fact that we collected so many signatures shows the citizens of Portland were really upset that they were going to fluoridate without a public vote,? says Kellie Barnes, spokeswoman for Clean Water Portland. ?We are entirely grassroots. The executive staff are all volunteers, none of us are paid. ? I?m a physical therapist and a mother who cares about not adding contaminants to our water.?

On paper, the fight over fluoridating Portland?s water supply looks absurdly uneven. The pro-fluoridation group Healthy Kids, Healthy Portland, as of May 13, had received $689,376 in cash and $65,093.64 in the form of donated supplies and labor. The anti-fluoridation Clean Water Portland received $194,333 and $59,137. Healthy Kids enjoys the backing of a diverse coalition that ranges from major health care and dental providers, such as Kaiser Permanente and the Oregon Dental Association (both have donated tens of thousands of dollars), to organized labor and almost all of the region?s major groups representing and organizing with people of color and low-income communities. Oregon?s Wild West campaign spending laws (they basically don?t have any) allow huge contributions: The Northwest Health Foundation alone has donated well over $200,000. The Urban League is the premiere advocacy group for Portland?s African-American community and it has an organizer devoted full-time to the cause.

Arguably most importantly, Healthy Kids and fluoridation have the endorsement of the massed forces of rationality and medical authority. Almost every credible national, state, and local health and science organization?private and public?gives its blessing to optimal levels of water fluoridation: The American Medical Association, the American Dental Association, the Environmental Protection Agency, the World Health Organization, American Academy of Family Physicians, and? the Center for Disease Control and Prevention, which named the measure one of the 10 greatest public health achievements of the 20th century. They all agree that fluoridated water is perfectly safe and extremely effective at preventing tooth decay.

Clean Water Portland?s anti-fluoridation supporters include the Pacific Green Party, Nutritional Therapy Association, Organic Consumers Association, Oregon Association of Acupuncture and Oriental Medicine, and the Cascade Club, a local libertarian think tank. The Portland chapter of the NAACP is the only local organization representing people of color that has come out against fluoride, but according to most political observers it is tiny and has very little influence. (United Latin American Citizens is also listed as a supporter because their national organization has opposed the policy generally, but according to Barnes their Portland chapter has not officially endorsed CWP.) Out-of-state supporters include the Fluoride Action Group and Kansas Taxpayers Network, which is a far-right group that recently merged with Americans for Prosperity. Anti-fluoride funding also comes from a variety of groups bearing the name of Joseph Mercola, a doctor the FDA censured multiple times for making untrue health claims. His website includes articles opposing fluoridation, vaccinations, and mammograms. Mercola.com also features an extensive interview with a man who denies that HIV causes AIDS.

Why the GOP dropped its boycott of Obama's Labor and EPA picks

Don't start singing "Kumbaya" just yet

Senate Republicans last week blocked committee votes on President Obama's picks to lead the Department of Labor and the Environmental Protection Agency, infuriating Democrats who have long complained about the GOP's obstructionism.

Yet this week, Republicans suddenly dropped their opposition, finally allowing Democrats to send both nominees on to the the full Senate.

On Thursday, the Senate Environment and Public Works Committee approved the nomination of Gina McCarthy to head the EPA on a party-line vote, 10-8. On the same day, the Health, Education, Labor, and Pensions (HELP) committee voted 12-10, also along party lines, to advance Labor Secretary nominee Thomas Perez.

The EPA vote came one week after Republicans refused to even show up for a vote on McCarthy, leaving Democrats short of a quorum. GOP committee members had previously demanded that McCarthy answer a staggering 1,100 questions about the EPA ? she currently heads the agency's air pollution office ? and then insisted they still needed more information.

As for Perez, he finally received a vote after Republicans on the HELP committee twice postponed previous votes. Most recently, they used an arcane procedural rule to prevent the committee from voting.

That Republicans finally stopped delaying the committee votes does not mean they've suddenly been placated. Rather, they're gearing up for a battle in the full Senate, where they'll have more power to block the nominations indefinitely via threatened filibusters.

Sen. David Vitter (R-La.) has said he'll force a 60-vote threshold on Perez, and Sen. Roy Blunt (R-Mo.) has already placed a hold on McCarthy's nomination. Given that both nominees garnered zero GOP votes in committee, it's clear they'll face stiff opposition in the full Senate.

Perez's nomination in particular could prove problematic, since leading Republicans like Senate Minority Leader Mitch McConnell (R-Ky.) have labeled him a "committed ideologue," and raised questions about his tenure with the Justice Department's civil rights division.

"His willingness, time and again, to bend or ignore the law and to misstate the facts in order to advance his far-left ideology lead me and others to conclude that he'd continue to do so if he were confirmed to another, and much more consequential, position of public trust," McConnell said in a statement last week.

In response, Democrats have mulled a so-called "nuclear option" of simply changing Senate rules to weaken the filibuster and allow them to approve both nominees, even in the face of unified GOP opposition.

Second court invalidates Obama recess appointment

(AP) ? A second federal appeals court has found that President Barack Obama exceeded his power when he bypassed the Senate to install a member to the National Labor Relations Board.

The ruling by the 3rd U.S. Circuit Court of Appeals in Philadelphia came on the same day that a Senate panel considered a slate of five nominees for full terms on the labor board. Senate Republicans said Thursday they would oppose two of the nominees ? Sharon Block and Richard Griffin ? because they currently sit on the board as recess appointments.

In its 2-1 decision ruling, the appeals court said that under the Constitution recess appointments can be made only between sessions of the Senate, not any time the Senate is away on a break.

The court's action mirrors a far-reaching ruling by the U.S. Court of Appeals in Washington, D.C., earlier this year. The Obama administration has appealed that ruling to the Supreme Court, arguing that such an interpretation would invalidate hundreds of recess appointments made by presidents over more than 100 years.

The latest ruling says Obama had no constitutional authority to install attorney Craig Becker to the labor board in 2010 while the Senate was adjourned for two weeks.

The White House did not immediately respond to a request for comment.

Both rulings have threatened to throw the labor board, the Consumer Financial Protection Board and other federal agencies with recess appointees into chaos. If they stand, hundreds of decisions by these agencies could be thrown out.

The narrow interpretation of a president's recess appointment power would also effectively make it impossible for the president to ever use that power, giving the Senate's ability to block administration nominees indefinitely.

Obama has made 32 recess appointments during his presidency, nearly all of which would be considered invalid under the interpretation of these courts. The rulings could also threaten the recess appointments of previous presidents. President George W. Bush made 141 such appointments in eight years.

On Capitol Hill, Tennessee Sen. Lamar Alexander, senior Republican on the Senate Health, Education, Labor and Pensions Committee, said he would not consider Block and Griffin because they refused to step down from the board after the District of Columbia Circuit ruled that they were unconstitutionally appointed. Block and Griffin said they wanted to abide by their oath to serve their country and argued that appeals courts have reached different conclusions about recess powers.

Democrats on the panel accused Republicans of obstructionism because the GOP and its allies in the business community have been unhappy with some of the union-friendly decisions issued by the board during Obama's administration. Unions warn that unless the nominees are confirmed soon, the board will be unable to function. It only has three members now, and the term of board chairman Mark Pearce expires in August.

In the 3rd Circuit case, the two-judge majority rejected the Obama administration's arguments that a Senate recess occurs any time lawmakers do not have a duty to attend, the Senate chamber is empty and the Senate cannot receive messages from the president.

"Defining recess in this way would eviscerate the divided-powers framework" of the Constitution, Judge D. Brooks Smith wrote in a 102-page decision. "If the Senate refused to confirm a president's nominees, then the president could circumvent the Senate's constitutional role simply by waiting until senators go home for the evening."

Smith, who was appointed by President George W. Bush, was joined in his opinion by Judge Franklin Stuart Van Antwerpen, an appointee of President Ronald Reagan.

A lengthy dissent came from Judge Joseph Greenaway Jr., who was appointed by Obama and joined the court in 2010. Greenaway said that under the majority's decision, the recess appointment power "is essentially neutered and the president's ability to make recess appointments would be eviscerated."

The case was brought by New Vista, a New Jersey nursing and rehabilitative care center that argued its nurses were supervisors who were not allowed to form a union. The labor board ruled in favor of the union and New Vista appealed. The company argued that the board did not have enough validly appointed members to reach a decision because Becker was not a valid appointee.

The labor board has five seats and needs at least three sitting members to conduct business. At the time of the New Vista ruling, it had the minimum of three, but one member was Becker, the recess appointee.

Becker is no longer on the NLRB, but the current board also has only three members, two of whom are Obama recess appointees. More than a hundred companies have appealed NLRB decisions this year arguing that the board does not have enough validly appointed members to conduct business.

Google+ gets a new multi-column card design and ability to automatically add hashtags (update: video)

Today, at Google I/O 2013, Big G revealed a new look for its social network. Starting later today, Google+ users will be seeing their social content in a new way thanks to a multi-column format fit for any size screen. The home page for G+ now has up to 3 columns populated with individual cards for posts and pictures, and the social network can intelligently learn the content of those posts and automatically add related hashtags for you. Columns appear or disappear depending upon the size of your screen, and cards can be flipped to reveal editing options, or moved to suit users' aesthetic tastes. Should you have the requisite screen real estate, pictures and videos expand to the width of multiple columns to further provide a more visually pleasing social experience. In order to eliminate clutter, Google + has adopted a familiar looking left-side menu layout that disappears until a hovering cursor (or presumably a swiping finger) reveals it.

Update: You can see the new layout and auto hashtagging in action in the video after the break.

Netflix keeps its lead in streaming video use at home, YouTube rules the road

Netflix keeps its lead in streaming video use at home, YouTube rules the road

When we last checked in with Sandvine's stat trackers, Netflix reigned supreme in online video traffic at home, especially downstream. It's still sitting pretty several months later, Sandvine tells AllThingsD. Quite possibly helped by the House of Cards debut, Netflix kept a healthy lead at 32.3 percent of downstream use on wired networks this past March. That's no mean feat when some of its competition took big strides forward -- YouTube jumped up to 17.1 percent, and Hulu likely rode sweeps season to get 2.4 percent.

In mobile, it's a different story. Netflix use on cellular almost doubled to 4 percent, but YouTube kept an uncontested lead at 27.3 percent of downstream use. It's not hard to see why after looking at other video formats people prefer on the road: raw HTTP video (19.2 percent) and Facebook (8.6 percent) were the next-closest, which suggests that many still grab snack-sized videos on their phones instead of full movies or TV shows. We don't expect the status quo to budge much in the near future, whether it's on mobile or a fixed-line. Without major initiatives from veterans or the arrival of a new upstart, it isn't clear just what would rock the boat.

(AP) ? "I hope that other women can benefit from my experience," Angelina Jolie wrote in a powerful op-ed article Tuesday, explaining her decision to go public with having her breasts removed to avoid cancer.

But amid the accolades for the film star's courageous revelation, doctors and genetic counselors were careful to note that her medical situation ? an inherited genetic mutation putting her at high risk of breast and ovarian cancer ? was very specific, and that her course of action made sense for only a small category of women.

Still, they hailed her bravery and said that she would surely help increase awareness ? and thus, perhaps, help save some lives.

"Having this conversation empowers us all," said Rebecca Nagy, a genetic counselor who works frequently with women who test positive for a defective version of the BRCA1 gene, as Jolie did. "It's wonderful what she's done."

In a stunning op-ed piece in the New York Times, Jolie, 37, began by speaking of her late mother, Marcheline Bertrand, who died of cancer at 56, before she was able to meet most of her grandchildren.

The actress revealed that beginning in February, she underwent three surgeries ? which she succeeded in keeping secret from the public ? in which her breasts were removed, and later replaced by implants.

"I wanted to write this to tell other women that the decision to have a mastectomy was not easy. But it is one I am very happy that I made," Jolie wrote. "My chances of developing breast cancer have dropped from 87 percent to under 5 percent. I can tell my children that they don't need to fear they will lose me to breast cancer."

The actress also hinted that she might, at some point, have her ovaries removed, saying that she had "started with the breasts" because her risk of breast cancer was higher than that for ovarian cancer. She did not say how long ago she was diagnosed with the faulty gene.

While admiring Jolie's straightforwardness, cancer surgeons and others in the medical community were quick to point out that hereditary cases of breast cancer account for only about 5 percent to 7 percent of all cases diagnosed each year. And those connected to the BRCA1 and BRCA2 genes are an even smaller group.

And so, women shouldn't just run off and get tested for those genes, said Dr. Robert Shenk, medical director of the Breast Center at the University Hospitals Case Medical Center in Cleveland.

"My worry is that people will be inappropriately tested," said Shenk. "Awareness is great, but people shouldn't just run in off the street and get a test."

Instead, he said, genetic counseling, including a close review of a patient's family history, is crucial.

Nagy, the genetic counselor, who is also president of the National Society of Genetic Counselors, agreed.

"The clues are in the family history. Has there been cancer in multiple generations?" she said. "Are there clusters of cancers, like breast and ovarian, on the same side of the family? Has the cancer been diagnosed at an early age ? under 50?"

If those factors exist, Nagy said, she conducts a thorough risk assessment with the patient. And if testing is warranted, there still needs to be some thought beforehand as to what one might do with the information.

"It might not necessarily be surgery," Nagy said. "It might be much more frequent screenings. Surgery isn't right for everyone."

That's the decision that Gabrielle Brett made ? at least initially. Brett was only 23 when she tested positive for the BRCA1 gene. She had just met her future husband, James, a month earlier. She wanted to have a family, so she waited.

But at age 29, her husband said she shouldn't wait any longer. She should have her breasts removed before they had kids, even though she wouldn't be able to nurse them. She ultimately agreed. She had the surgery and then had two children. Now 35, she is two weeks from her due date with her third.

Brett woke up in the middle of the night Tuesday, read about Jolie's article on Facebook, and excitedly woke her husband. "It's amazing to hear that someone so famous went through the same thing," she said in a telephone interview. "It makes me realize we are all on the same journey."

Brett, who lives in Shaker Heights, Ohio, also figures that Jolie went through some tough moments, however serene she sounded in her article.

"I'm sure it wasn't quite so simple," she said. "There's sadness, anger, fear. I did a lot of crying alone in the car. But once I had the surgery, I felt a huge weight come off of me. I was no longer worrying whether there was cancer growing inside me somewhere. I felt nothing but relief."

And, she said, it was crucial that she was accompanied throughout her journey by "my own Brad Pitt" ? her husband, who was there through every moment, as Jolie says partner Pitt was for her at the Pink Lotus Breast Center in southern California.

There is one part of the journey Brett has not tackled yet: removal of her ovaries. That, she said, will come a bit later, when she is 40.

Doctors stress that no one solution is right for everyone who tests positive. And even for those with a risky family history, it's not necessarily always right to test right away, they say.

"You don't necessarily want to test an 18-year-old, sending her into a panic at such a young age," said Shenk. "You might consider that she's unlikely to get cancer in her 20s. You would maybe test her later."

Another potential downside to the testing: the cost, which can reach $3,000, though it's usually covered by insurance and there are programs for women who can't afford it.

And some women might simply not be prepared for the results, said Dr. Eric Winer, head of the breast program at the Dana-Farber Cancer Institute in Boston. "Once you get the information, you have to be able to deal with it," he said.

If one does test positive, Winer stressed, it could be a reasonable solution to undergo intensive surveillance with MRI tests and mammograms. Or, some women choose to remove only their ovaries, which in pre-menopausal women seems to reduce the risk of breast cancer, too.

But in Jolie's case, Winer said, it's hard to argue with her choice of preventive surgery. "I tend to be a less-is-more doctor," said Winer. "But I do think the choice she made is a rational, reasonable one."

There is a risk, he noted, that with the actress's celebrity power, people will see her choice and think it's the only one. If they do get cancer, "most women are well-served by conservative surgery, as in a lumpectomy," with chemotherapy and/or radiation, he said.

But any risk is outweighed by Jolie's ability to promote awareness, Winer added. "The more people who ask their doctors about this, the better."

Dr. Kristi Funk, founder of the Pink Lotus Center where Jolie was treated, agreed. "We hope that the awareness she is raising around the world will save countless lives," Funk said.

Jolie's most positive influence, some say, may be in the fact that such a glamorous woman has come forward ? in great detail ? to talk about how one can lose one's breasts and still remain, well, a woman.

"I do not feel any less of a woman," Jolie wrote in her article. "I feel empowered that I made a strong choice that in no way diminishes my femininity."

That impressed Nagy, the genetic counselor. "For women, so much is tied to sexuality, to sensuality," she said. "Many women feel defined by that.
