Genetic Region For Tame Animals Discovered: Horse Whisperers, Lion Tamers Not Needed Posted: 09 Jun 2009 05:00 PM PDT In what could be a breakthrough in animal breeding, scientists have discovered a set of genetic regions responsible for animal tameness. This discovery should help animal breeders, farmers, zoologists, and anyone else who handles and raises animals to more fully understand what makes some animals interact with humans better than do others.

Muscle Atrophy: When The Body Cannibalizes Itself Posted: 09 Jun 2009 05:00 PM PDT During desperate times, such as fasting or muscle wasting that afflicts cancer or AIDS patients, the body cannibalizes itself, atrophying and breaking down skeletal muscle proteins to liberate amino acids. A new study shows that muscle atrophy is a more ordered process than was previously thought.

Newly Discovered Chemical Weapon In Poison Frogs' Arsenal Posted: 09 Jun 2009 05:00 PM PDT New research documents a surprising chemical weapon used by some Amazonian poison frogs. The study identified for the first time a family of poisons never before known to exist in these brightly colored creatures or elsewhere in nature: the N-methyldecahydroquinolines. The authors then speculated on its origin in the frogs' diet, most likely ants.

Insomnia With Objective Short Sleep Duration In Men Is Associated With Increased Mortality Posted: 09 Jun 2009 05:00 PM PDT Men with insomnia and sleep duration of six or fewer hours of nightly sleep are at an increased risk for mortality, according to a new research.

Network Creates Virtual Super-telescope Posted: 09 Jun 2009 05:00 PM PDT Vast quantities of data are transferred in real time from telescopes around the world to a supercomputer in the Netherlands, where researchers combine the information to create high-resolution images of distant objects in space.

Concussion Experts: For Kids -- No Sports, No Schoolwork, No Text Messages Posted: 09 Jun 2009 05:00 PM PDT When it comes to concussions, children and teens require different treatment, according to international experts. The new guidelines say children and teens must be strictly monitored and activities restricted until fully healed. These restrictions include no return to the field of play, no return to school, and no cognitive activity.

Discovery Raises New Doubts About Dinosaur-bird Links Posted: 09 Jun 2009 02:00 PM PDT Researchers have made a fundamental new discovery about how birds breathe and have a lung capacity that allows for flight -- and the finding means it's unlikely that birds descended from any known theropod dinosaurs.

Defeating Nicotine's Double Role In Lung Cancer Posted: 09 Jun 2009 02:00 PM PDT A lung cancer treatment that inhibits nicotine receptors was shown to double survival time in mice, according to new research.

Thinnest Superconducting Metal Ever Created Posted: 09 Jun 2009 02:00 PM PDT A superconducting sheet of lead only two atoms thick, the thinnest superconducting metal layer ever created, has been developed by physicists.

Common Chemotherapy Drug Can Trigger Fatal Allergic Reactions Posted: 09 Jun 2009 02:00 PM PDT A chemotherapy drug that is supposed to help save cancer patients' lives, instead resulted in life-threatening and sometimes fatal allergic reactions. A new study identified 287 hypersensitivity reactions and 109 deaths in patients who received Cremophor-based paclitaxel, a solvent-administered chemotherapy. Two patients who died from an allergic reaction had highly curable early-stage breast cancer. The allergic reactions are believed to be caused by the solvent, and the actual number of deaths is likely higher.

Structure Of Bacteria Responsible For Traveler's Diarrhea Identified Posted: 09 Jun 2009 02:00 PM PDT Researchers have solved the structure of thin hair-like fibers called "pili" or "fimbriae" on the surface of bacteria that cause traveler's diarrhea. The findings have important implications for creating better therapeutics against diarrheal diseases.

Relationship Found Between Napping, Hyperactivity, Depression And Anxiety Posted: 09 Jun 2009 02:00 PM PDT Napping may have a significant influence on young children's daytime functioning, according to a new research.

When Young Men Are Scarce, They're More Likely To Play The Field Than To Propose Posted: 08 Jun 2009 09:00 PM PDT In places where young women outnumber young men, research shows the hemlines rise but the marriage rates don't because the young men feel less pressure to settle down as more women compete for their affections.

Dioxins In Food Chain Linked To Breastfeeding Ills Posted: 08 Jun 2009 09:00 PM PDT Exposure to dioxins during pregnancy harms the cells in rapidly-changing breast tissue, which may explain why some women have trouble breastfeeding or don't produce enough milk, according to a new study.

Biologist Discovers Pink-winged Moth In Chiracahua Mountains Posted: 08 Jun 2009 09:00 PM PDT Biologists have discovered a new species of moth. The moth has distinct bright pink wings, which prompted Walsh to name it after his wife.

Writing In Air Not Pie In The Sky: Student Device Turns Phone Gestures Into Email Posted: 08 Jun 2009 09:00 PM PDT Engineering students have taken advantage of the accelerometers in emerging cell phones to create an application that permits users to write short notes in the air with their phone, and have that message automatically sent to an e-mail address.

Study On Papua New Guinea's Long-beaked Echidna Reveals Elusive Habits Posted: 08 Jun 2009 09:00 PM PDT A research intern working in the wilds of Papua New Guinea has successfully completed what many other field biologists considered "mission impossible" -- the first study of a rare egg-laying mammal called the long-beaked echidna.

African Bird Species Could Struggle To Relocate To Survive Global Warming Posted: 08 Jun 2009 09:00 PM PDT African bird species could struggle to relocate to survive global warming because natural features of the landscape will limit where they can move to, according to new research.
