More than 80,000 chemicals are used or produced in the U.S., and the Environmental Protection Agency (EPA) has placed restrictions or bans on just five. But the agency signaled its intent at the end of last year to possibly add restrictions to four chemicals that are widely used in making products such as toys, household items and medical equipment, according to Scientific American.
Suzaku detected X-rays produced when heavily ionized iron atoms recapture an electron. This view combines infrared images from the ground (red, green) with X-ray data from NASA's Chandra X-Ray Observatory (blue).

A new type of supernova remnant still holds the embers of the fireball that first blossomed thousands of years ago. The remnant gas retains ions with the imprint of temperatures 10,000 times hotter than the sun's surface, according to scientists who made the observations with the Japan-U.S. Suzaku space observatory.
Cell phone exposure reverses Alzheimer's in mice, synthetic bones are as good as the real thing, synthetic alcohol is better than the real thing, and gamblers place their bets on Mother Nature: 2010 is off to a strong start!

According to a new study, organic feed produces measurably different gene expression in chickens compared to normal feed, even if the ingredients are the same. The finding surprised researchers at the Louis Bolk Institute in the Netherlands, where a large research project is underway to examine possible health effects of differently produced feed.
In this depiction of the rod-shaped E. coli, two flagella trail from one end while hairlike pili surround a capsule full of tangled nucleoids.
This 41-inch-long sculpture of the Escherichia coli bacterium is part of British artist Luke Jerram’s “Glass Microbiology” series of portraits. Other organisms he has vitrified include HIV, SARS and swine flu.
The rise of psychopharmacology has led doctors to not only treat mental illnesses like regular diseases, but think of them as such as well. Turns out, schizophrenia may be more than just a disease in concept, but actually a virus itself. According to new research, as much as eight percent of the human genome consists of viruses that inserted themselves into our DNA for replication, including the gene that causes schizophrenia.
The geological time scale, with its familiar Cretaceous, Cambrian, and Eocene periods, works great as a calendar for the history of the Earth. Indeed, the different periods only cover the 3.8 billion years of life on Earth, with everything before that time lumped into one nondescript eon called the Hadean. But for some geologists, that lack of specificity simply won't work any more.
Frustrated by referring to Hadean-era events with vague phrases like "around the time of Moon formation" or "shortly after Earth cooled", four scientists, including two from NASA, have chopped up the Hadean into distinct geologic periods, and even extended the time scale back to the formation of the solar system, with a new eon called the "Chaotian."
Australian Aborigine mythology begins in a period known as the "dream time", before the emergence of humanity. Many stories about the dream time include legends about stars, gods, or rocks falling from the sky. And new research utilizing Google Earth surveys of the outback show that many of those myths may actually be historically accurate.
Millisecond pulsars left in the wake of supernovas could provide the basis for a type of "galactic GPS," radio astronomers say. A growing constellation of known pulsars could allow the scientists to make the first direct detection of gravitational waves -- a predicted consequence of Einstein's relativity theory. The concept might even help guide future spacecraft and explorers, not to mention errant galactic hitchhikers.
The journal Nature, ever the forward-looking publication, is finished with all of this best-of-the-last-decade nonsense. To celebrate the dawn of a new decade, the editors tapped experts across the scientific community, asking them simply "where will your field be ten years from now, and how will we get there?" Our favorite five predictions are collected below.
