This release is available in German. The analyses of an international team of researchers led by Svante Pääbo of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, show that the genetic variation of Denisovans was extremely low, suggesting that although they were present in large parts of Asia, their population was never large for long periods of time. In addition, a comprehensive list documents the genetic changes that set apart modern humans from their archaic relatives. Some of these changes concern genes that are associated with brain function ...

EAST LANSING, Mich. — Bacteria in hyenas' scent glands may be the key controllers of communication. The results, featured in the current issue of Scientific Reports, show a clear relationship between the diversity of hyena clans and the distinct microbial communities that reside in their scent glands, said Kevin Theis, the paper's lead author and Michigan State University postdoctoral researcher. "A critical component of every animal's behavioral repertoire is an effective communication system," said Theis, who co-authored the study with Kay Holekamp, MSU zoologist. ...

KANSAS CITY, MO—The skin, the blood, and the lining of the gut—adult stem cells replenish them daily. But stem cells really show off their healing powers in planarians, humble flatworms fabled for their ability to rebuild any missing body part. Just how adult stem cells build the right tissues at the right times and places has remained largely unanswered. Now, in a study published in an upcoming issue of Development, researchers at the Stowers Institute for Medical Research describe a novel system that allowed them to track stem cells in the flatworm Schmidtea mediterranea. ...

FINDINGS: The Affordable Care Act will fund more community health centers, making primary care more accessible to the underserved. But this may not necessarily lead to better access to subspecialty care. In a new study, researchers from the David Geffen School of Medicine and Robert Wood Johnson Foundation Clinical Scholars program at UCLA and colleagues investigated the ways in which community health centers access subspecialty care. They identified six major models and determined which of those six offered the best access: Tin cup ...

DURHAM, N.C. -- By measuring the unique properties of light on the scale of a single atom, researchers from Duke University and Imperial College, London, believe that they have characterized the limits of metal's ability in devices that enhance light. This field is known as plasmonics because scientists are trying to take advantage of plasmons, electrons that have been "excited" by light in a phenomenon that produces electromagnetic field enhancement. The enhancement achieved by metals at the nanoscale is significantly higher than that achievable with any other material. Until ...

"There is not enough radio spectrum to account for everybody's handheld portable device," said Jeffrey Rhoads, an associate professor of mechanical engineering at Purdue University. The overcrowding results in dropped calls, busy signals, degraded call quality and slower downloads. To counter the problem, industry is trying to build systems that operate with more sharply defined channels so that more of them can fit within the available bandwidth. "To do that you need more precise filters for cell phones and other radio devices, systems that reject noise and allow signals ...

LA JOLLA, CA----Scientists at the Salk Institute for Biological Studies have discovered a key genetic switch by which plants control their response to ethylene gas, a natural plant hormone best known for its ability to ripen fruit, but which, under ...

When an invading bacterium or virus starts rummaging through the contents of a cell nucleus, using proteins like tiny hands to rearrange the host's DNA strands, it can alter the host's biological course. The invading proteins use specific binding, firmly grabbing onto particular sequences of DNA, to bend, kink and twist the DNA strands. The invaders also use non-specific binding to grasp any part of a DNA strand, but these seemingly random bonds are weak. Emory University biophysicists have experimentally demonstrated, for the fist time, how the nonspecific binding of ...

Hot Towers are towering clouds that emit a tremendous amount of latent heat (thus, called "hot"). NASA research indicates that whenever a hot tower is spotted, a tropical cyclone will likely intensify. Less than 14 hours after the TRMM satellite captured an image of Ileana's rainfall and cloud heights, Ileana strengthened into a hurricane on Aug. 29. NASA's Tropical Rainfall Measuring Mission (TRMM) satellite captured a view of Ileana's rainfall rates on Aug. 29 at 2:17 a.m. EDT and saw the heaviest rainfall rates, near 50 mm (2.0 inches) per hour in a band of thunderstorms ...

Tropical Storm Tembin made landfall in the in southwestern South Korea and NASA's Aqua satellite captured the extent of the storm's elongated cloud cover, revealing the effect of wind shear on the storm. Tembin moved through the Myeongnyang Strait and made landfall on Aug. 30, 2012 at 0000 UTC (Aug. 29 at 8 p.m. EDT) in the southwestern tip of South Korea. NASA's Aqua satellite's Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured a visible, true-color image of Tropical Storm Tembin around the time of landfall in southwestern South Korea. The image ...

Tropical Storm Kirk intensified into a hurricane today, Aug. 30, while another tropical depression was born. Satellite imagery revealed Hurricane Kirk and newborn Tropical Depression 12 romping through the central Atlantic Ocean today, while Tropical Storm Isaac continues to drench the U.S. Gulf coast and Mississippi Valley. Kirk became the Atlantic Ocean season's fifth hurricane today, Aug. 30. On Aug. 30 at 7:45 a.m. EDT, a visible image from NOAA's GOES-13 satellite captured all three tropical cyclones in a panoramic shot of the Atlantic Ocean basin. The visible image ...

HOUSTON -- (Aug. 30, 2012) -- The threads of an evolutionary mystery that dates to the birth of molecular biology are beginning to unravel, thanks to a new investigation by computational bioengineers at Rice University and the University of Texas MD Anderson Cancer Center. In new research published online this week in PLOS Computational Biology, Rice's Oleg Igoshin and MD Anderson's Christian Ray offer a possible explanation for the existence of jointly controlled clusters of genes called operons, which are found in bacterial chromosomes but not in those of higher order ...

Previous research has shown that personality traits such as impulsivity or compulsiveness are indicators of an increased risk of addiction. Now, new research from the University of Cambridge suggests that these impulsive and compulsive personality traits are also associated with a traumatic upbringing during childhood. The study was published today, 31 August, in the journal American Journal Psychiatry. Led by Dr Karen Ersche, the Cambridge researchers aimed to identify risk factors that make a person vulnerable to developing drug dependence. They examined 50 adults ...

Dr. Matthew Loop, whose busy chiropractic office is located in Lilburn GA, uses a combination of approaches to help relieve the discomfort and stress associated with back pain. His approach includes chiropractic, soft tissue therapy and rehabilitation services. This combination offers patients quick relief. "The problem with auto injuries," says Dr. Loop, "is that they can manifest themselves in so many different ways, making pain management for the patient very difficult. Some patients suffer from generalized pain that is combined with pain located in ...
