From International Herald Tribune:

Amanda Kitts lost her left arm in a car accident three years ago, but these days she plays American football with her 12-year-old son, and changes diapers and bear-hugs children at the three Kiddie Cottage day care centers she owns in Knoxville, Tennessee.

Kitts, 40, does this all with a new kind of artificial arm that moves more easily than other devices and that she can control by using only her thoughts.

"I'm able to move my hand, wrist and elbow all at the same time," she said. "You think, and then your muscles move."

Her turnaround is the result of a new procedure that is attracting increasing attention because it allows people to move prosthetic arms more automatically than ever before, simply by using rewired nerves and their brains.

Senate Passes Stimulus Bill Containing $1.3 Billion for NASA

From Yahoo News/Space.com:

WASHINGTON - The U.S. Senate passed an $838 billion economic stimulus package Tuesday that includes $1.3 billion for NASA - more than double the amount the House approved Jan. 28 for the U.S. space agency in its version of the bill.

The Senate voted 61-37 on its version of the bill, which proposes spending $450 million to narrow the five-year gap between the scheduled 2010 retirement of the space shuttle and 2015 debut of its successor. The House put no money into addressing the gap.

Wind Turbines In Europe Do Nothing For Emissions-Reduction Goals

Under current EU law, German wind turbines aren't helping to reduce CO2 emissions. They simply allow Eastern European countries to pollute more. REUTERS

From Spiegel Online:

Despite Europe's boom in solar and wind energy, CO2 emissions haven't been reduced by even a single gram. Now, even the Green Party is taking a new look at the issue -- as shown in e-mails obtained by SPIEGEL ONLINE.

Germany's renewable energy companies are a tremendous success story. Roughly 15 percent of the country's electricity comes from solar, wind or biomass facilities, almost 250,000 jobs have been created and the net worth of the business is €35 billion per year.

But there's a catch: The climate hasn't in fact profited from these developments. As astonishing as it may sound, the new wind turbines and solar cells haven't prohibited the emission of even a single gram of CO2.

Twitter Fast Growing Beyond Its Messaging Roots

From Wired:

Thanks to its open-ended design and a thriving user community, Twitter is fast outgrowing its roots as a simple, easy-to-use messaging service. Enterprising hackers are creating apps for sharing music and videos, to help you quit smoking and lose weight -- spontaneously extending the text-based service into one of the web's most fertile (and least likely) application platforms.

Hardware hackers have set up household appliances to send status alerts over Twitter, like a washing machine that tweets when the spin cycle is through, or a home security system that tweets whenever it senses movement inside the house. Others have incorporated Twitter into their DIY home automation systems. Forgot to turn off the lights? Send a tweet to flip the switch by remote control.

Teens Spend Average Of 87 Hours A Year Looking At Porn Online

Teenagers are spending more than eight hours a week browsing the internet for soft porn, plastic surgery and family planning websites

From The Daily Mail:

The average teenager spends one hour and 40 minutes a week browsing sites for pornography, according to new research.

That equates to 87 hours a year spent surfing for porn. A further hour and 35 minutes is spent looking at dieting and weight loss websites.

The study of 1,000 youngsters found the average teenager was online 31 hours each week looking at soft pornography, plastic surgery, dieting, family planning and emotional support.

Another hour and eight minutes is dedicated to exploring cosmetic surgery websites, to learn about breast surgery, bum lifts and collagen implants.

The research was conducted by CyberSentinel.co.uk, a computer software that enables parents to block websites and monitor use of the internet.

Biologists Find Gene Network That Gave Rise To First Tooth

From Science Daily:

ScienceDaily (Feb. 10, 2009) — A new paper in PLoS Biology reports that a common gene regulatory circuit controls the development of all dentitions, from the first teeth in the throats of jawless fishes that lived half a billion years ago, to the incisors and molars of modern vertebrates, including you and me.

"It's likely that every tooth made throughout the evolution of vertebrates has used this core set of genes," said Gareth Fraser, postdoctoral fellow at Georgia Tech's School of Biology.

The first vertebrates to have teeth were a group of eel-like jawless fish known as the conodonts that had teeth not in their mouth, but lining the throat. This particular group is long since extinct, but some modern fish retain teeth in the throat (pharynx). Dr. Fraser and colleagues studied tooth formation in a group of fish known for their rapid rate of evolution, the cichlids of Africa's Lake Malawi. The cichlids have teeth both in their oral jaws, like humans, and deep in their throats on a pharyngeal jaw. A co-author of the paper, Darrin Hulsey, first identified a surprising positive correlation between the number of teeth in the oral jaw and in the throat in these fish.

Mythic Birthplace of Zeus Said Found

The Chariot of Zeus image is from the 1879
"Stories from the Greek Tragedians" by Alfred Church.

From Live Science:

The Greek god of thunder and lightning had Earthly beginnings, and scientists think they finally know where.

Ancient Greeks first worshipped the omnipotent Zeus at a remote altar on Mount Lykaion, a team of Greek and American archaeologists now think. During a recent dig at the site, the researchers found ceremonial goods commonly used in cult activity and dated at over three millennia old, making them the earliest known "appearance" of Zeus in Greece.

The discovery challenges the idea that Zeus worship began on the Greek island of Crete, which at least one classical historian names as the god's mythic birthplace. The latest finds on Mount Lykaion, in the mainland province of Arcadia, are as old as the idea of Zeus himself, said the project's senior research scientist David Romano, of the University of Pennsylvania.

"This new evidence strongly suggests that there were drinking (and perhaps feasting) parties taking place on the top of the mountain in the Late Helladic period, around 3,300 or 3,400 years ago," Romano said.

Televisions 'To Be Fitted In Contact Lenses Within Ten Years'

Channels could be changed by voice, making remote controls a thing of the past

From The Telegraph:

Televisions could be fitted into contact lenses within ten years, according to analysts.

The sets would be powered by the viewer's body heat, according to Ian Pearson, a so-called "futurologist" who has advised leading companies including BT on new technologies.

Mr Pearson told the Daily Mail he believed that channels could be changed by voice command or via a wave of the hand.

Meanwhile "emotional viewing" could be another development in television technology, according to a report commissioned by the technology retailer Comet.

A "digital tattoo" fitted to the viewer would pick up on the feelings of characters on screen and create impulses causing them to feel the same way.

The European Space Agency's Herschel Observatory Is Finished And Ready To Go Into Orbit

Key features on the Herschel space observatory. The inset compares Herschel with Hubble and the future James Webb Space Telescope.

From The BBC:

Stare into the curve of Herschel's mirror too long and you get a slightly giddy feeling that comes from not being able to judge where its surface really starts.

It is enchanting, spectacular and - at 3.5m in diameter - it will soon become the biggest telescope mirror in space, surpassing that of Hubble.

The great 18th Century astronomer William Herschel would have been astonished by the silver sensation that now bears his name.

The European Space Agency (Esa) is certainly very proud of its new observatory. It has been working on the venture for more than 20 years.

"The mirror is an enormous piece of hardware," enthused Thomas Passvogel, Esa's programme manager on the Herschel space observatory.

Bacteria, Not Flu, Cause Of 1918 Pandemic

The 1918 flu pandemic is estimated to have caused the death of between 50 million and 100 million people in approximately 18 months (Source: US National Archives)

From ABC News/Reuters:

Strep infections and not influenza may have killed most people during the 1918 influenza pandemic, which suggests predictions about a new pandemic could be exaggerated, say US researchers.

The findings suggest that amassing antibiotics to fight bacterial infections may be as important as stockpiling antiviral drugs to battle flu, they say.

Professor Keith Klugman of Emory University, Atlanta and colleagues report their findings in the journal Emerging Infectious Diseases.

The team looked at information available about the 1918 flu pandemic, which killed between 50 million and 100 million people globally in the space of about 18 months.

From Yahoo News/AP:

CAIRO – A storeroom housing about two dozen ancient Egyptian mummies has been unearthed inside a 2,600-year-old tomb during the latest round of excavations at the vast necropolis of Saqqara south of Cairo, archaeologists said Monday.

The tomb was located at the bottom of a 36-foot deep shaft, said Egypt's top archaeologist, Zahi Hawass. Twenty-two mummies were found in niches along the tomb's walls, he said.

Eight sarcophagi were also found in the tomb. Archaeologists so far have opened only one of the sarcophagi — and found a mummy inside of it, said Hawass' assistant Abdel Hakim Karar. Mummies are believed to be inside the other seven, he said.

Digital Overload Is Frying Our Brains

From Wired News:

Paying attention isn't a simple act of self-discipline, but a cognitive ability with deep neurobiological roots — and this complex faculty, says Maggie Jackson, is being woefully undermined by how we're living.

In Distracted: The Erosion of Attention and the Coming Dark Age, Jackson explores the effects of "our high-speed, overloaded, split-focus and even cybercentric society" on attention. It's not a pretty picture: a never-ending stream of phone calls, e-mails, instant messages, text messages and tweets is part of an institutionalized culture of interruption, and makes it hard to concentrate and think creatively.

Newborn Brain Cells 'Time-Stamp' Memories

Image from Impact Lab

From E! Science News:

LA JOLLA, CA—"Remember when…?" is how many a wistful trip down memory lane begins. But just how the brain keeps tabs on what happened and when is still a matter of speculation. A computational model developed by scientists at the Salk Institute for Biological Studies now suggests that newborn brain cells—generated by the thousands each day—add a time-related code, which is unique to memories formed around the same time. "By labeling contemporary events as similar, new neurons allow us to recall events from a certain period," speculates Fred H. Gage, Ph.D., a professor in the Laboratory for Genetics, who led the study published in the Jan. 29, 2009, issue of the journal Neuron. Unlike the kind of time stamp found on digital photographs, however, the neuronal time code only provides relative time.

Ironically, Gage and his team had not set out to explain how the brain stores temporal information. Instead they were interested in why adult brains continually spawn new brain cells in the dentate gyrus, the entryway to the hippocampus. The hippocampus, a small seahorse-shaped area of the brain, distributes memory to appropriate storage sections in the brain after readying the information for efficient recall.

Motivating Minds -- Why People Procrastinate

From The Economist:

People procrastinate when asked to think in the abstract

TO SOME there is nothing so urgent that it cannot be postponed in favour of a cup of tea. Such procrastination is a mystery to psychologists, who wonder why people would sabotage themselves in this way. A team of researchers led by Sean McCrea of the University of Konstanz, in Germany, reckon they have found a piece of the puzzle. People act in a timely way when given concrete tasks but dawdle when they view them in abstract terms.

Dr McCrea and his colleagues conducted three separate studies. First they recruited 34 students who were offered €2.50 ($3.30) for completing a questionnaire within the subsequent three weeks. Half of the students were then sent an email asking them to write a couple of sentences on how they might go about various activities, such as opening a bank account or keeping a diary. The others were asked to write about why someone might want to open a bank account or keep a diary.

Meet The First Commercial Rocketship Pilots.

From Air And Space Smithsonian Magazine:

In the old days it was straightforward enough. The planet had two corps of astronauts, Soviet and U.S., and to join one, you had to be a military test pilot. But now the rules have changed. You don’t have to be an American or a Russian anymore, and you don’t even have to be a government employee.

In 2004, Burt Rutan and his small company in Mojave, California, Scaled Composites, broke the government monopoly on human spaceflight. The company built SpaceShipOne using the same carbon fiber molding techniques used by airplane homebuilders everywhere, at the ridiculously paltry cost of $25 million. At the controls on its first flight into space sat not a steely-eyed missile man forged in the cold war but a 63-year-old high school dropout from South Africa. “I’m just a guy,” Mike Melvill exulted after SpaceShipOne’s inaugural flight into space. “An old guy!” The implication was inescapable. If he could drive a spaceship, so could anyone.

Space Telescope To Boost Hunt For Alien Earths

Kepler Telescope (Image from Nasa)

From The New Scientist:

HOW common are alien Earths - small, rocky planets orbiting at the right distance to be not so hot that water boils and not so cold that it stays frozen? Till now clues have been hard to come by, because surveys have not been sensitive enough to find many such planets.

That should soon change thanks to the Kepler space telescope, which NASA is expecting to launch on 5 March. Its unique positioning in the solar system and unprecedented sensitivity mean that for the first time we will be able to see Earth-size planets in the "habitable zone" of their stars - the region where the temperature on the planet should be right for liquid water to exist at its surface.

From Science Daily:

ScienceDaily (Feb. 7, 2009) — Instant pictures showing how the sun's energy moves inside plants have been taken for the first time, according to research out February 6 in Physical Review Letters.

The images unravel some of the inner workings of the most efficient solar energy process on earth - photosynthesis. Inside a photosynthetic protein, the sun's energy is efficiently guided across the molecule to drive a chemical reaction that stores energy as food and takes in carbon dioxide. Scientists would very much like to harness this process as they search for new energy solutions to replace fossil fuels. To do this, they need to understand this energy transport process in more detail.
