Obama's Hypocrisy

Obama attacks Bush administration policy, describing it as ad hoc, then describes how he will create a system that allows for the "prolonged detention" of terrorists without trial. I have to say I'm a little surprised.

Thomas Friedman on how to sell a carbon tax (from his NYT Op-Ed column, "Moore's Law and the Law of More"):

Have no doubt: From right-wing tea parties to coal states to manufacturers, there is going to be a no-holds-barred campaign to kill any carbon price signal, including cap and trade. A vast army of lobbyists is already working against it. Only President Obama can blunt this. Only he has the platform for framing and elevating the issue properly and taking it to the American people with the passion and clarity needed to move the country. It will take more than one speech.

Here’s one way to start: “My fellow Americans, I want to speak to you about a new economic law. You’ve heard of Moore’s Law in information technology. I’d like to speak to you about the ‘Law of More’ in energy technology. Americans, Indians, Chinese, Africans, we all want more — more comfort in our homes, more mobility in our lives, more technologies with which to innovate. But there is only one way all 6.3 billion of us can have more and not make this an unlivable planet, and that is by living our lives and running our businesses in more sustainable ways and properly accounting for it.

“Right now we’re paying a huge price — a tax — for everyone trying to achieve more in an unsustainable way. But the ‘More Tax’ is not imposed by the U.S. government. It is a tax imposed by the market and will continue rising indefinitely as more and more people want more and more stuff. It will steadily drive up gasoline prices, home heating prices and factory electricity prices. But because this ‘More Tax’ is set by the market and not the government, many opponents contend that there’s nothing to be done: ‘Oh, $4.50 a gallon gasoline — that’s just the market at work. We can’t do anything about that.’ And then all that tax money out of your pocket goes to enrich oil companies and petro-dictators.

“My proposal is that today we fix a durable price on carbon-based fossil fuels, but set it to begin only in 2011, after we’re out of this recession. Every home builder, air-conditioning manufacturer, gasoline refiner, carmaker will know that it’s coming and will, I believe, immediately look for ways to profit from and invest in more energy efficient systems. Yes, the cost of gasoline or kilowatt hours will rise in the short term. But in the long term, your actual bills and expenses will go down because your car, appliances and factory will become steadily more productive and give you more power for less energy.

“I call it the ‘Carbon Tax Cut.’ You won’t receive the dividend in the first week or month, but you will get it soon, and it will be a permanent tax cut, a gift that will keep on giving.

“So those are our choices, folks — an escalating ‘More Tax’ forever, premised on immediate gratification and short-term thinking, or a ‘Carbon Tax Cut’ forever, which is exactly what you’ll get from establishing a carbon price signal that shapes the market in favor of American interests and not those of our adversaries and competitors. If you’re with me, write your member of Congress and senator today.”


Here's a tidbit from John Tierney's NYT Findings column, "Ear Plugs to Lasers - The Science of Concentration":
When something bright or novel flashes, it tends to automatically win the competition for the brain’s attention, but that involuntary bottom-up impulse can be voluntarily overridden through a top-down process that Dr. Desimone calls “biased competition.” He and colleagues have found that neurons in the prefrontal cortex — the brain’s planning center — start oscillating in unison and send signals directing the visual cortex to heed something else.
“It takes a lot of your prefrontal brain power to force yourself not to process a strong input like a television commercial,” said Dr. Desimone, the director of the McGovern Institute for Brain Research at M.I.T. “If you’re trying to read a book at the same time, you may not have the resources left to focus on the words.”
Here are some tips from the author of "Rapt,” a guide to the science of paying attention, Winifred Gallagher.

Ms. Gallagher advocates meditation to increase your focus, but she says there are also simpler ways to put the lessons of attention researchers to use. Once she learned how hard it was for the brain to avoid paying attention to sounds, particularly other people’s voices, she began carrying ear plugs with her. When you’re trapped in a noisy subway car or a taxi with a TV that won’t turn off, she says you have to build your own “stimulus shelter.”

She recommends starting your work day concentrating on your most important task for 90 minutes. At that point your prefrontal cortex probably needs a rest, and you can answer e-mail, return phone calls and sip caffeine (which does help attention) before focusing again. But until that first break, don’t get distracted by anything else, because it can take the brain 20 minutes to do the equivalent of rebooting after an interruption. (For more advice, go to

Rich = Green (not just money)

Here are two bold predictions made yesterday by John Tierney of the NYT:

1. There will be no green revolution in energy or anything else. No leader or law or treaty will radically change the energy sources for people and industries in the United States or other countries. No recession or depression will make a lasting change in consumers’ passions to use energy, make money and buy new technology — and that, believe it or not, is good news, because...

2. The richer everyone gets, the greener the planet will be in the long run.

Fraction Neurons

From NewScientist (full article):

FRACTIONS may be written as the ratio of two whole numbers, but that's not how our brains process them. Instead it seems we respond to fractions directly, without processing whole numbers along the way. This suggests that kids, who often dread fractions, could be taught them more intuitively.

Previous tests have shown that specifc groups of neurons respond to different whole numbers, with the number one altering the firing patterns of different neurons than the number three. Now Simon Jacob and Andreas Nieder of the University of Tübingen in Germany have shown that we have fraction-specific neurons too.

The pair scanned the brains of adults as they were shown a variety of different fractions - either as numerical ratios or in words. In both cases, specific groups of neurons altered their firing patterns. Crucially, control experiments showed that the volunteers weren't responding first to whole numbers, and then calculating the ratio, but were reacting to the fraction itself (The Journal of Neuroscience, DOI: 10.1523/jneurosci.0651-09.2009).

Fractions tend to be taught as ratios of whole numbers, but Nieder says this may not tap our neural machinery in the most constructive way, making fractions harder to grasp than they need to be.

Bed Bugs an Increasing Problem

Bed bugs have always been somewhat of a mythical creature to me. Probably because because of the little rhyme recited every night by my parents as they tucked me in: "Good night, sleep tight, don't let the bed bugs bite. And if they do, get out your shoe, and beat them 'til they're black and blue." (The second line wasn't recited by my parents, but learned later from peers at school.)

Anyway, I have never taken this warning particularly seriously, but there may now be reason to heed the warning with a little more care. Check it out (from 60 Second Science):
Federal environmental regulators are hosting the first-ever "bed bug summit" to discuss emerging infestations of the insects around the country.

At the behest of the Environmental Protection Agency (EPA), some 300 people gathered in Arlington, Va., yesterday and today to swap ideas about how to get rid of the critters, whose bites make up to half of victims itchy with hives. While there's no official count of how many people are bitten, cities including New York, Chicago, Boston and Cincinnati have reported growing bed bug problems, which experts blame in part on declining use of pesticides amid concerns about their health effects.

New Breed of Cancer Vaccine Shows New Promise

Seattle bio-tech company Dendreon has announced that it's anti-cancer vaccine, Provenge, prolongs the lives of prostate cancer patients. 500 patients for who no other therapies were effective participated in the study, but the exact results have not been released (leading to some suspicion regarding the truth of the claim).

While most vaccines rely on prevention, provenge works by targeting immune cells/molecules to established tumors. Many believe this type of vaccine could be less toxic and more effective than chemotherapy or radiation, and when used in conjunction with chemo, the results appear to be synergistic.

However, while preliminary results are certainly promising, the FDA has been reluctant to approve Provenge - inciting outcry and criticism by many cancer-patient advocates. Maybe these latest results will help (when the details are finally released - and if the claims are true).

New Yorkers to be Entered in Science Experiment

Michael Bloomberg and Thomas R. Frieden forego the constraints of compelling evidence and consent to engage NY in the largest unapproved science experiment in a long time.

Check out this article by John Tierney from the NYT:
Suppose you wanted to test the effects of halving the amount of salt in people’s diets. If you were an academic researcher, you’d have to persuade your institutional review board that you had considered the risks and obtained informed consent from the participants.

You might, for instance, take note of a recent clinical trial in which heart patients put on a restricted-sodium diet fared worse than those on a normal diet. In light of new research suggesting that eating salt improves mood and combats depression, you might be alert for psychological effects of the new diet. You might worry that people would react to less-salty food by eating more of it, a trend you could monitor by comparing them with a control group.

But if you are the mayor of New York, no such constraints apply. Read more...

WASHINGTON (Reuters) - A Florida utility and a real estate developer are aiming to bring the country's first solar-powered city to the Sunshine State.

FPL Group Inc's utility Florida Power & Light is working with the realty group Kitson & Partners to construct what the utility says will be the world's largest photovoltaic solar plant in a planned, environmentally friendly city near Fort Myers in southwestern Florida.

Called Babcock Ranch, the city will aim to build 19,500 houses and about 6 million square feet of retail, light industrial, and office space when it is completed, the developers said.

Rare Megamouth Shark Caught in the Phillipines

On the morning of March 30, fishermen casting their nets in the Burias Pass, a centrally located channel in the Philippine archipelago, got the catch—not to mention surprise—of their lives: a megamouth shark so rare that some people still consider it a "cryptid", a creature that is seen so infrequently science can't confirm its existence.

That's likely an overstatement when it comes to the megamouth, first spotted in 1976 in waters near the Hawaiian island of Oahu. But, according to the Florida Museum of Natural History (FLMNH) in Gainesville, which dubbed last month's catch "megamouth 41" (this being only the 41st observation of one of these sharks)—this is the eighth specimen snagged in the Pacific Ocean near the Philippines.

Like Loud Misic, Scared of Going Deaf - Fear No More

Anti-Loudness Protein

Fans of club music and rock concerts who like the volume cranked up to 11 but want to save their hearing might someday pop a pill rather than plugging their ears. Scientists have pinpointed the biochemical mechanism in ears that works to limit damaging effects of loud sound. When a noise registers in the brain as too loud, the protein nAChR, located on sensory hair cells in the inner ear, kicks in to limit the ability of the hair cells to respond. Mice genetically altered to produce a more potent nAChR could not hear soft sounds, and they suffered less permanent damage to their hearing when scientists blasted 100-decibel noise at their ears. "We know some drugs can modify the protein," says Paul Fuchs of Johns Hopkins University, who published the findings in the January 20 PLoS Biology. "But we need to know more about specific amounts" before a sound-protecting drug can be made. So don't toss the earplugs yet.

Anatomically Normal Girl with Y Chromosome

This is quite amazing and could prove to be a significant finding for the field of developmental biology, and it might not have been discovered if it weren't for prenatal genetic screens. Check it out (from NewScientist):

A seven-year-old girl with a Y chromosome is providing new clues about a possible "master switch" of maleness.

The girl has the normal chromosome count – 46 – and should be male. Other children who have the male sex chromosome but do not appear to be boys have been found to have gene mutations that temper the Y chromosome's effects. However this child doesn't have ambiguous gonads, shrivelled testes or other developmental defects. She instead has a normal vagina, cervix and set of ovaries.

A team led by Anna Biason-Lauber, of University Children's Hospital in Zurich, Switzerland, thinks the patient's normalcy is due to mutations in a poorly understood gene on chromosome 17 called CBX2.

The child's unique condition might not have been discovered were it not for tests performed before birth to check for major genetic defects, such as an extra copy of chromosome 21 that causes Down's syndrome. Those tests came up negative and indicated the child would be a boy.

Better Light Bulb?

The pending extinction of traditional incandescent bulbs in the United States and abroad has created an enormous market opportunity for energy-efficient lighting technologies. The current shortcomings of compact fluorescent lights and pricey LED bulbs show that future dominance of the American socket is still very much up for grabs.

Vu1 (that is, “view one”), a company based in Seattle, thinks it has a shot.

The company’s tag line, “light without compromise,” suggests that it’s keenly aware of the biggest stumbling block for most next-generation lighting technologies: they don’t behave like incandescent bulbs, which is what most consumers are accustomed to. “We believe that we’ve got something here that will be much more comparable with people’s expectations than what’s been out there until now,” said Vu1’s chief executive officer, David Grieger.

"Do Parents Matter?"

Sorry Mom and Dad, but I didn't say it. From

Do Parents Matter?
A researcher argues that peers are much more important than parents, that psychologists underestimate the power of genetics and that we have a lot to learn from Asian classrooms.
In 1998 Judith Rich Harris, an independent researcher and textbook author, published The Nurture Assumption: Why Children Turn Out The Way They Do. The book provocatively argued that parents matter much less, at least when it comes to determining the behavior of their children, than is typically assumed. Instead, Harris argued that a child’s peer group is far more important. The Nurture Assumption has recently been reissued in an expanded and revised form. Mind Matters editor Jonah Lehrer chats with Harris about her critics, the evolution of her ideas and why teachers can be more important than parents.

Tuning in on Back Pain

Full article from NewScientist:

TUNING forks, brushes and erasers can all help to quickly and cheaply reveal which painkiller to prescribe for back pain.

From a patient's description, doctors struggle to distinguish between neuropathic pain from nerve damage, such as in sciatica, and pain from inflammation, yet each requires a different painkiller. Only expensive tests such as MRI scans reveal the source precisely, leading Joachim Scholz of Massachusetts General Hospital in Boston and his colleagues to look for a quicker, cheaper way.

The team compiled a list of quick questions and physical tests and assessed the response of patients diagnosed with each type of pain. From this, they whittled the list down to six questions and 10 physical tests that included rubbing brushes, safety pins, tuning forks and pencil erasers on the back. Together, the tests can show whether or not the pain is neuropathic (PLoS Medicine, DOI: 10.1371/journal.pmed.1000047).

The whole list takes just 15 minutes to complete and also distinguishes between three types of neuropathic pain.

Green Porno: Fly

For the Bird Watchers

From Wired Science:
With an old computer and 30 dollars worth of off-the-shelf components, you can gear up with cutting edge avian monitoring technology and help save the birds.

For years, birdwatchers counted by sight during the daytime. The night — when most migratory birds travel — was literally hidden to them. But that's changing. Anyone can attach a microphone to a computer running birdcall-identifying software and track birds passing overhead in the darkness.

"You wouldn't be able to understand what's happening at night without this technology," said Andrew Farnsworth, a Cornell University ornithologist. "And when it comes to recording the things I work on, that's something anyone can do."

Scientists already depend on citizen birdwatchers for data that provides the foundation for estimates of species health and behavior. Their spare-time jottings are collated in efforts like the Great Backyard Bird Count, eBird, North American Bird Phenology Program and Project Feederwatch. With hundreds of species threatened by habitat loss, climate change and pollution, that data is now invaluable for conservation efforts.

But because many species migrate at night and are hard to find during the daytime, birders can miss them, said Farnsworth, or are forced to use proxy measures: If a bird seen yesterday isn't seen today, then it probably left. "It's not that the proxy methods are bad," he said, "but we're finding this method of nocturnal tracking can be incredibly powerful." Read more...

Galaxies Spell Out Cosmic Warning/Apology!

From NewScientist:
Trolling through a physics preprint server today, a colleague of mine spotted several highly intriguing papers.

One (pdf), from a project called Galaxy Zoo that invites volunteers to analyse and categorise galaxies in images from the Sloan Digital Sky Survey, reports on a strange new class of galaxy cluster (see images).

The team writes: "Upon detailed inspection, the morphologies of individual galaxies and close systems approximate the familiar geometric shapes of letters of the basic modern Latin alphabet. . . . the existence of these messages might indicate intelligent life beyond our own."

From the observed phrases ("Caution! Structure formation in progress", "Delays possible for 7 Gyr" and "We apologise for the inconvenience"), it's clear that these are cosmic road signs, and that the creator of the signs speaks the Queen's English (this I deduce both from the "s" in apologise and from the general politeness of the message).

Masturbation Relieves Hay Fever

From NewScientist:

Spring is here and with it come the woes of hay fever. Never fear, however, as there may be a quick and pleasurable treatment to clear those bunged noses, for guys at least – a well-timed ejaculation.

That's what Sina Zarrintan, a neurologist from the Tabriz Medical University in Iran proposes, anyway. The logic behind the proposal is based on the fact that the nose and the genitals are both connected to the same part of the nervous system that controls certain reflexes – the sympathetic nervous system.

A blocked nose is caused by swollen and inflamed nasal blood vessels, irritated by an infection or pollen in the air. But during ejaculation, the sympathetic nervous system constricts blood vessels across the body. That should soothe the swollen nasal blood vessels, freeing the airway for normal breathing, according to Zarrintan. Read more...

What If We Had No Forests?

From NewScientist:

THE acres upon acres of lush tropical forest in the Amazon and tropical Africa are often referred to as the planet's lungs. But what if they are also its heart? This is exactly what a couple of meteorologists claim in a controversial new theory that questions our fundamental understanding of what drives the weather. They believe vast forests generate winds that help pump water around the planet.

If correct, the theory would explain how the deep interiors of forested continents get as much rain as the coast, and how most of Australia turned from forest to desert. It suggests that much of North America could become desert - even without global warming. The idea makes it even more vital that we recognise the crucial role forests play in the well-being of the planet. Read more...

Stem Cells May Provide Cure For Hearing Loss

From NewScientist:
Human ear cells vital for hearing have for the first time been created in the lab, and could eventually yield new treatments for hearing loss.

Such cells have been created before from mice, but the new cells will reveal more about how human hearing works.

"We believe these are the first from humans," says Marcelo Rivolta of the University of Sheffield, UK and head of the team presenting its findings on Monday in Oxford at a conference on stem cells.

"Stem cell therapy for hearing loss is still some years away, but this research is incredibly promising and opens up exciting possibilities," says Ralph Holme, director of biomedical research at the UK Royal National Institute for Deaf People, which co-funded the research with Deafness Research UK.

The team grew the cells from cochlear stem cells they'd isolated from fetuses following abortions, with the full consent of the women involved.

Gene Linked to Motor Skill Acquisition

Entire article from

Scientists know that small variations in certain genes can predispose people to cancers or heart disease. Now researchers are starting to show a direct, quantifiable effect on learning traceable to these types of genetic influences: single-nucleotide polymorphisms. A difference in just one amino acid in a protein might explain why some people learn new motor skills faster and reach higher levels of performance.

The protein, called brain-derived neurotro­phic factor (BDNF), is a key driver of synaptic plasti­city, the ability of the connections between brain cells to change in strength. This plasticity is an important factor in learning, explains neurologist Janine Reis, who led the study at the National Institutes of Health. According to Reis, this finding offers the first evidence that slight variations in BDNF’s structure affect learning ability.

Volunteers with one type of BDNF learned faster and performed better at a task in which they had to grip a handle more or less tightly to move a computer cursor through a sequence of targets. Those with a different variant never reached the skill level acquired by the faster learners. (The researchers excluded people who play video games.)

Other groups have found that the BDNF version that Reis linked with poorer acquisition of skills is associated with reduced function of the hippocampus, a brain region involved in motor learning.

This difference in BDNF may be a clue as to why certain people excel at athletic perfor­mance, Reis says, or it may help predict how well patients will recover motor skills after a stroke. Her team and others are gearing up to look at gene variants in stroke patients, hoping to find new targets for drug therapy.

Making a Stink Over Mushrooms

From "Can science keep mushroom farmers from stinking up the Commonwealth of Pennyslvania?"

Editor's Note: This is the fifth in a series of six features on the science of food, running daily from March 30 through April 6, 2009.

STATE COLLEGE, Pa.—Donald "Buster" Needham and his sons Artie and Don are moving their mushrooms out of Pennsylvania. Needham, 73, took over the business from his own father 50 years ago, but his West Grove operation—fueled with several hundred tons of steaming horse and chicken manure each week—has proved too stinky for city folk buying up homes in this township 40 miles (65 kilometers) west of Philadelphia.
