Sumatran 'tiger map' reveals tiger population higher than expected
Scientists have created the highest resolution map of the Sumatran tiger distribution ever produced, revealing that the island now hosts the second largest tiger population on earth. The research, carried out with the Wildlife Conservation Society's Indonesia Program and Forum HarimauKita, will be published in a special issue of Integrative Zoology, on tiger conservation and research...
Warring Greeks find peace in ancient Egypt
Naukrtis, a Greek trade emporium on Egyptian soil, has long captured the imagination of archaeologists and historians. Not only is the presence of a Greek trading settlement in Egypt during the 7th and 6th century B.C.E. surprising, but the Greeks that lived there in harmony hailed from several Greek states which traditionally warred amongst themselves.
New nanotube material stays rubbery over a more than 1,000 degree temperature range
(PhysOrg.com) -- Silicone rubber is used in many applications in which a material is required to remain rubbery over a wide temperature range, since it retains its properties over the approximate range of -55°C to 300°C. Now a new material made of carbon nanotubes has been developed that retains its viscoelastic properties over a temperature range almost five times larger.
Gene-environment interactions could influence several psychiatric disorders
(PhysOrg.com) -- Male mice born with a genetic mutation that's believed to make humans more susceptible to schizophrenia develop behaviors that mimic other major psychiatric illnesses when their mothers are exposed to an assault to the immune system while pregnant, according to new Johns Hopkins research.

New type of nuclear fission discovered
(PhysOrg.com) -- Nuclear fission, or the splitting of a heavy nucleus, usually results in symmetrical fragments of the same mass. Physicists attribute the few known examples of fission that is asymmetric to the formation in the resultant fragments of "magic" nuclei, which are extremely stable nuclei with all energy levels filled. Now, experiments at the European particle physics laboratory at the...
Scientists find gene linked to congenital heart defect
(PhysOrg.com) -- A gene that can cause congenital heart defects has been identified by a team of scientists, including a group from Princeton University. The discovery could lead to new treatments for those affected by the conditions brought on by the birth defect.
Understanding shape-shifting polymers (w/ Video)
(PhysOrg.com) -- Shape-memory polymers are not a new discovery, as anyone who has played with Shrinky-Dinks or who has used heat-shrink tubing for wires in an electronic circuit can testify. But now, thanks to new analysis by researchers at MIT, the behavior of these interesting materials has been mathematically modeled in detail, which should make it easier to use the materials in new ways;...
Lesbian, gay and bisexual teens singled out for punishment
Lesbian, gay and bisexual (LGB) adolescents are about 40 percent more likely than other teens to be punished by school authorities, police and the courts, according to a study by Yale University researchers.

Researchers: Include data about societal values in endangered species decisions
The U.S. Fish and Wildlife Service is excluding significant research findings about human threats to protected species, researchers argue, even when the law governing the agency's actions requires the use of all relevant data in determining whether species need protection from extinction.
Study finds family acceptance of LGBT youth protects against depression, substance abuse, suicide
For the first time, researchers have established a clear link between accepting family attitudes and behaviors towards their lesbian, gay, bisexual and transgender (LGBT) children and significantly decreased risk and better overall health in adulthood. The study shows that specific parental and caregiver behaviors -- such as advocating for their children when they are mistreated because of their...
