Sushi chef, restaurant charged with serving whale
WASHINGTON (Reuters) - A California sushi chef and the restaurant in which he worked have been charged with illegally serving meat from an endangered Sei whale, the Justice Department said on Thursday. Kiyoshiro Yamamoto, 45, and the parent company of the popular restaurant The Hump in Santa Monica were charged late on Wednesday with violating the Marine Mammal Protection Act which makes it illegal to sell any kind of whale meat.

Researchers Gain New Insights into the Mystery of Thalidomide-Caused Birth Defects
Half a century ago, thousands of pregnant women in 46 countries took a drug for morning sickness that would later be discovered to cause severe malformations in developing fetuses. Worldwide, roughly 10,000 affected children nicknamed "thalidomide babies" were born with multiple defects, including the characteristic shortened upper limbs (a condition known as phocomelia, Greek for "seal limbs"), before the drug was discontinued in 1961 after four years on the market.

Arranged Marriages Can Be Real Love Connection
Think arranged marriages are loveless? Not so, says psychologist Robert Epstein, a contributing editor for Scientific American MIND magazine. He spoke March 10 at the 92nd Street Y’s Tribeca site in New York City:“And there’s even a study published in India [Usha Gupta and Pushpa Singh of the University of Rajasthan, 1982] but using an American love scale, called the Rubin Love Scale, that compared love in love marriages in India, because they have those, too, to love in arranged marriages. And in this particular study, love in the love marriages starts out very high. And then over time it decreases. That’s what all of our studies show. And in the arranged marriages--and this is true in my work, too--we see the love starting out relatively low. Because in some cases the people barely know each other, sometimes they’ve had a half an hour of contact in total before they got married. And then it increases gradually, surpasses the love in the love marriages at about five years. And 10 years out it’s twice as strong.”

New Hope for Battling Brain Cancer (preview)
In May 2006 Dwayne Berg woke up on a gurney in a Seattle emergency room, an IV in his arm and a team of doctors and nurses working him up. The last thing the 42-year-old financial executive could remember was running on a treadmill at his gym, part of his regular fitness regimen. He had suffered a seizure and tumbled off the machine, and although he had not hurt himself in the fall, doctors had asked for an MRI scan of his brain to see if they could find a cause for the seizure.They did, and the news was not good: the scan showed a large mass in the left frontal lobe that turned out to be a malignant glioma, a brain cancer that is almost invariably fatal. Berg underwent standard treatment: an operation to remove the tumor, followed by chemotherapy and radiation to eradicate any cancer cells that might remain.
Divining the Right Drug
Imagine suffering from the crushing weight of major depression, then finally getting diagnosed and starting treatment with a drug--only to realize after two months that the medication, despite its unpleasant side effects, is not alleviating your depression. Unfortunately, this experience is far from rare: more than two thirds of patients with depression have no luck with the first medication they are prescribed and must also endure the withdrawal effects that come with discontinuing a drug before trying a new one. Finding the right treatment can prove a lengthy, painful process of trial and error. A new technology, however, may bypass this ordeal by gauging very early in a treatment regimen how well a drug is working based on the patient’s brain waves.The technology, called quantitative electroencephalography (QEEG), measures a person’s brain-wave pattern with EEG and then compares it with a database of normal samples to detect abnormal function. In a study published in the September 2009 issue of the journal Psychiatry Research , scientists used QEEG to record brain activity in subjects with major depressive disorder before they began treatment, after one week on an antidepressant and after eight weeks on the drug--the period it takes such drugs to achieve full effect. Changes in the QEEG readout after just one week of medication predicted 74 percent of the time whether patients would experience either a recovery or a remission of symptoms by the end of eight weeks.
Will the Clean Tech Bubble Burst?
BOSTON--Economic bubbles are now famous, and the collapse of the dot-com business a decade ago made the bursting of bubbles infamous. A panel of experts here at the Going Green East conference yesterday ended up in a lively, entertaining and, at times, contentious debate over whether the growth of so-called clean tech--renewable energy and environmentally friendly technologies--has entered the bubble stage, if that bubble is bursting...or if a bubble has ever existed.Lucky for anyone reading these words, the conference organizers at Always On videotaped the panel and have already posted it online for viewing. (Use this link then scroll two thirds down the page to the embedded session title "The Cleantech Bubble?".) The first 10 minutes have some of the best fireworks from two pioneers of major technology ramp-ups, including Bob Metcalfe , who invented the Ethernet and drove the vast growth of the Internet, and George Gilder , whose prognostications about hot telecomm technologies and the darling companies behind them greatly pumped up the dot-com bubble. If you listen even longer you'll hear all four panelists ultimately bash subsidies for technology of all kinds, itself worth the price of admission--which in this case, is free.

Genomes for the whole family
By Janelle WeaverBy sequencing the genomes of three patients with rare genetic disorders, and comparing them with genetic information from unaffected family members, two studies have managed to narrow down the causes of the diseases.Between them, the analyses bring the number of individuals who have had their full genomes sequenced from seven to twelve.A team led by David Galas of the Institute for Systems Biology in Seattle, Wash., sequenced the genomes of a family of four in which the two children had extremely rare genetic disorders--Miller syndrome and primary ciliary dyskinesia1.

IPCC Errors Prompt Review by International Science Academies
African crop yields wither, along with the Amazon rainforest; Himalayan glaciers disappear by 2035. These are the erroneous predictions ascribed to the most recent report from the U.N. Intergovernmental Panel on Climate Change (IPCC)--a document reviewed by some 2,500 scientists and other experts as well as vetted by more than 190 countries. So does the fact that a few errors crept into a more than 3,000 page report merit a revision of IPCC processes?

Introducing the Newest Scientific Measurement: A "Rosenfeld" for Energy Savings
Energy-efficiency gurus want to create the "Rosenfeld" as a simple unit of energy savings.It may not roll off the tongue like the ohm, watt or volt, but it would follow in their tradition. Many call Arthur Rosenfeld, a recently retired member of the California Energy Commission , the "godfather of energy efficiency." One Rosenfeld would represent saving 3 billion kilowatt-hours per year--the same amount generated by a 500-megawatt coal-run power plant .
Sunshine is free, so can photovoltaics be cheap?
Here's how to make a solar cell from silicon : take one solid block of doped silicon, saw it into thin wafers, layer said semiconductors beneath a panel of transparent glass, connect them to a metal electrode that can channel away the electrons knocked loose by incoming photons and turn it into a photovoltaic device. That process has at least two flaws: such silicon is expensive, contributing more than half to the final price of a solar photovoltaic, and sawing it turns as much as half of that silicon into wasted grit.*

Few Studies Compare the Efficacy of Medical Treatments
The forward momentum of medical progress is manifest, it could be argued, in the $50 billion spent in 2008 on pharmaceutical research and development in the quest to bring new drugs to market. But little scientific or governmental infrastructure exists to ensure that each new treatment is actually an improvement over existing therapies--and to tease out what therapies are best for which patients.
Message to Mosquitoes: Urine Trouble
You know how uncomfortable it feels when you really have to go to the bathroom? And you have to hold it in? If researchers get their way, disease-carrying mosquitoes will spend their last moments being that uncomfortable. Cornell University scientists [Peter M. Piermarini, et al] have been trying to disrupt the life cycle of Aedes aegypti mosquitoes, which spread dengue fever. The mosquitoes pick up the virus when they feed on one human and transmit it in their saliva to their next victim.There’s no vaccine for dengue, and no fully protective treatment. So the only recourse has been to figure out how to best kill the mosquitoes themselves. Here’s where urination comes in. When the mosquito takes a blood meal, it has to get rid of fluid and salt so it doesn’t overload--and die. Scientists have discovered a key protein in the renal tubes of these mosquitoes that helps with the necessary excretion. Blocking the protein keeps a mosquito from urinating. [See http://bit.ly/defrih ] Without whizzing, they become too heavy to fly away. The researchers say they’re thus more likely to be swatted or eaten. So look for new insecticides that stop mosquitoes from lightening their liquid load. With fatal results.
Chimps Talk with Their Hands
The origins of language have long been a mystery, but mounting evidence hints that our unique linguistic abilities could have evolved from gestural communication in our ancestors. Such gesturing may also explain why most people are right-handed.Researchers at the Yerkes National Primate Research Center recently examined captive chimpanzees and found that most of them predominantly used their right hand when communicating with one another--for example, when greeting another chimp by extending an arm. The animals did not show this hand preference for noncommunicative actions, such as wiping their noses. Such lateralized hand use suggests that chimpanzees have a system in their left brain hemisphere that is coupled to the production of communicative gestures, says study author William Hopkins. The same cerebral hemisphere is host to most language functions in humans, which hints that an ancestral gestural system could have been the precursor for language, he says.
Why is talking with gestures easier than talking without them?
Why is talking along with gestures so much easier than trying to talk without gesturing? -- Lionel Halvorsen, Cornith, Tex.
End-of-Days Danger

Invasion of the Drones: Unmanned Aircraft Take Off in Polar Exploration
A multinational, robotic air corps is quietly invading the polar regions of the earth. Some catapult from ships; some launch from running pickup trucks; and some take off the old-fashioned way, from icy airstrips. The aircraft range from remote-controlled propeller planes--of the type found at Toys “R” Us--to sophisticated, high-altitude jets. All are specially outfitted, not with weapons but with scientific instruments.Unmanned aircraft have made headlines in the mountains of Afghanistan, but the technology has quickly trickled down to scientists seeking a less expensive, safer way to study the earth’s poles. Researchers have begun to put unmanned aerial systems, or UASs, to a variety of tasks, from monitoring the ozone layer to counting seal populations. Thanks to lower costs and improved technologies, “it’s absolutely exploded in the past couple of years,” says Elizabeth Weatherhead, who is an environmental scientist at the University of Colorado at Boulder.
One's Enough: People Who Donate a Kidney Live Just as Long as Those Who Don't
Every 30 minutes, all of the blood in our bodies is filtered through two fist-size kidneys. But diseases such as diabetes can cause them to fail, leading to a build-up of chemicals in the blood that without dialysis (mechanical blood filtration) or a kidney transplant would be fatal. And the wait for a new kidney can be long, unless someone you know is willing to give one of theirs to you.

PET project: Using organic catalysts to make more biodegradable plastics
Whereas most discarded plastic water and beverage bottles (those imprinted with a number 1 within a triangular arrow) can be recycled , the resulting second-generation plastic is generally unusable for making new plastic bottles. This is because the polyethylene terephthalate (PET) thermoplastic polymer used to make the original bottles is often made with the help of metal oxide or metal hydroxide catalysts that linger in the recycled material and weaken it over time.
Storing megawatts: Liquid-metal batteries and electricity
Making aluminum requires a lot of electricity. That's because the metal bonds tightly to oxygen and it takes a lot of energy to break that bond. In essence, the process of making aluminum is a giant battery with the silvery metal being reduced to purity at the cathode while oxygen bonds with the carbon anode to make, you guessed it, CO2. It takes roughly 15 kilowatt-hours of electricity to make just one kilogram of aluminum via electrolysis.
Smokestash Industry: ARPA-E Seeks Breakthroughs in Carbon Capture Technology
WASHINGTON--Every second, our bodies capture carbon dioxide in our tissues, transport it via the blood, and dump it in the lungs from where it is exhaled. This unconscious process is yet another way humans contribute to the accumulation of the greenhouse gas in the atmosphere--albeit in a minuscule volume compared with burning fossil fuels . The key to this metabolic process is an enzyme called carbonic anhydrase and it's efficiency at capturing and releasing CO2 is what human engineers want to mimic at the power plant scale.

Funding from ARPA-E could allow researchers to take a liquid metal battery from a 'shot glass size cell to a pizza box cell.'

Picture the world’s oceans, glimmering sapphire under the heat of the sun and the protection of the ozone layer. Look closer, there’s a patch of brown in the middle of all that blue. It’s a bloom of phytoplankton called Trichodesmium , a “world famous” nitrogen fixer.
Can Aging Nuclear Reactors Be Safe?
On Nov. 4, 2008, two divers were cleaning sludge and silt from an entry bay for water pumps that serve Constellation Energy Nuclear Group's Nine Mile Point nuclear power plant near Oswego, N.Y.In the midst of the operation, the diver and the hose tender shifted their positions and the diver lost control of a plastic suction hose, leaving its trailing section in front of one of the water pipe entries. The force of the water flow, at 9,000 gallons a minute, severed a section of hose and sucked it into one of the system's pumps, fouling it. As the team tried to cope with that problem, a smaller piece of the unattended free end of the hose was pulled into a second water pump, according to an inspection report by the Nuclear Regulatory Commission .
