Would-be inventors seeking to capitalize on the discovery of radioactivity in the late 19th century produced a plethora of questionable medical devices and treatments. Among the most famous of these was the Revigator, an earthenware vessel that, according to an advertisement, would infuse drinking water with 'the lost element of original freshness--radioactivity.'
A new study led by researchers at NYU Langone Medical Center is shedding new light on the action of Rho, a key regulatory protein in E. coli and many other bacteria. The study reveals a new paradigm to understand the molecular principles of gene transcription. This work could potentially lead to the development of new types of antibiotics that could target Rho and its crucial functions.
Men who smelled shirts of ovulating women subsequently had higher levels of testosterone than men who smelled shirts worn by non-ovulating women, suggesting that testosterone levels may be responsive to smells indicating when a woman is fertile.
An expert panel of librarians, library scientists, publishers, and university academic leaders today called on federal agencies that fund research to develop and implement policies that ensure free public access to the results of the research they fund “as soon as possible after those results have been published in a peer-reviewed journal.”
Is there anybody out there? In Alejandro Jenkins’ case, the question refers not to whether life exists elsewhere in the universe, but whether it exists in other universes outside of our own.
A team of University of Wisconsin-Madison researchers has created the strongest form of collagen known to science, a stable alternative to human collagen that could one day be used to treat arthritis and other conditions that result from collagen defects.
On the marine microbial stage, there appears to be a vast group of understudies only too ready to step in when "star" microbes falter. New work provides the first evidence that microorganisms can be rare for long periods before completely turning the tables to become dominant when ecosystems change.
The University of Maryland has been awarded $10.3 million in stimulus funds by the National Institute of Standards and Technology to build an advanced quantum science lab.

A Mayo Clinic research study published in the January issue of The American Journal of Gastroenterology finds that St. John’s wort is not an effective treatment for irritable bowel syndrome (IBS). While antidepressants are frequently used to treat IBS, to date, no study has examined the success of using the herbal supplement St. John’s wort in treating IBS.
Researchers from the Biotechnology Foundation Laboratories at Thomas Jefferson University have identified a way to increase the oil in tobacco plant leaves, which may be the next step in using the plants for biofuel. Their paper was published online in Plant Biotechnology Journal.
The timing of molar emergence and its relation to growth and reproduction in apes is being reported by scientists at Arizona State University’s Institute of Human Origins. “We can use the same techniques to calculate ages at first molar emergence from the fossils of early hominids that just happened to die while their first molars were erupting,” they say.
Just like teenagers at a prom, proteins are tended by chaperones whose job it is to prevent unwanted interactions among immature clients. And at the molecular level, just as at the high school gym level, it's a job that usually requires a lot of energy.
In order to preserve our DNA, cells have developed an intricate system for monitoring and repairing DNA damage. Yet precisely how the initial damage signal is converted into a repair response remains unclear. Researchers at the Salk Institute for Biological Studies have now solved a crucial piece of the complex puzzle.

New approaches that account for the flexibility of attackers could improve security threat assessments.
Women play longer in popular online game, are happier players than men and healthier than both sexes in general population – but are less honest about their time online, according to a new study in the Journal of Communication.
Carotenoids, found in green leafy vegetables and colored fruits, have been found to increase visual performance and may prevent age-related eye diseases, according to a study in the Journal of Food Science, published by the Institute of Food Technologists. Authors from the University of Georgia compiled the results of multiple studies on the effects of the carotenoids lutein and zeaxanthin on visual performance. These carotenoids play an important role in human vision, including a positive impact on the retina.
Researchers discover new ‘golden ratios’ for female facial beauty.
To give his students the hands-on experience of studying water beneath the Earth's surface, Tufts Geology Professor Grant Garven took the ambitious step of having a system of underground boreholes installed on Tufts' Medford/Somerville campus. Monitoring wells are uncommon on university campuses in the Boston area. Garven's project will twill enhance his students' understanding of hydrogeology – which is the study of how water moves underground through soil and bedrock.
The roving, walking robotic soldiers of the “Terminator” films are becoming less sci-fi and more certain future every day. Now, a team of robotics researchers from the Virginia Tech College of Engineering will build a team of fully autonomous cooperative battle-ready robots as part of a 2010 international war games challenge that could spur real-life battle bots.
A NIST team has prototyped a new handheld touch-screen application, a fingerprint identification system suitable for use by the FBI's Hostage Rescue Team.
Solitary waves that run a long distance without losing their shape or dying out are a special class of waves called solitons. These everlasting waves are exotic enough, but theoreticians at the Joint Quantum Institute now believe that there may be a new kind of soliton that's even more special.

His work is expected to make a significant contribution to contemporary physics.
Proteins, which perform such vital roles in our bodies as building and maintaining tissues and regulating cellular processes, are a finicky lot. In order to work properly, they must be folded just so, yet many proteins readily collapse into useless tangles when exposed to temperatures just a few degrees above normal body temperature.
Researchers’ theory: An increase in population size may mean sounds used in mate competition need not travel as far as before; acoustic information extracted from songs could be useful population monitoring tool
Measures being proposed by the U.S. Climate Action Partnership to curb greenhouse gas emissions are unlikely to affect potential long-term economic growth in the United States, according to a study by RTI International.
The pistol gunsight has remained unchanged for more than a century, which is bad news for the eye and brain since there is a lot to process visually during aiming, says a University of Alabama at Birmingham vision scientist. He has designed a new gunsight that relies on subconscious ability and promises to reduce the time law enforcement, professional and amateur shooters need for target practice to improve marksmanship.
