New poison dart frog species discovered in Donoso, Panama Posted: 26 Sep 2014 06:36 PM PDT A bright orange poison dart frog with a unique call has been discovered in Donoso, Panama. Because this new frog species appears to be found in only a very small area, habitat loss and collecting for the pet trade are major threats to its existence. The authors recommend the formulation of special conservation plans to guarantee its survival.

New molecule found in space connotes life origins Posted: 26 Sep 2014 06:36 PM PDT Hunting from a distance of 27,000 light years, astronomers have discovered an unusual carbon-based molecule contained within a giant gas cloud in interstellar space. The discovery suggests that the complex molecules needed for life may have their origins in interstellar space.

Countries must work together to stop organ traffickers, says researcher Posted: 26 Sep 2014 06:36 PM PDT The author of new research into organ trafficking has called for a concerted international effort to confront the problem. Although there is no internationally agreed definition, 'organ trafficking' is broadly defined as situations in which people are tricked into giving up organs, may sell them for financial gain but are not paid for as agreed.

Preference for built-up habitats could explain rapid spread of tree bumblebee in UK Posted: 26 Sep 2014 12:04 PM PDT Tree bumblebee populations could be spreading because the bees readily live alongside humans in towns and villages. This sets the species apart from other common British bumblebees -- which could explain how tree bumblebees have managed to colonize much of the UK while many other bumblebee species have been declining.

Biochemists solve 'address problem' in cells that leads to lethal kidney disease Posted: 26 Sep 2014 06:13 AM PDT Research published by biochemists may lead to a new treatment, or even a cure, for a rare, genetic kidney disease that afflicts children, and may provide important insights into treatments for Parkinson's disease, Alzheimer's disease and other degenerative diseases.

Exploring connection between empathy, neurohormones and aggression Posted: 26 Sep 2014 06:13 AM PDT Researchers examined whether assessed or elicited empathy would lead to situation-specific aggression on behalf of another person, and to explore the potential role of two neurohormones in explaining a connection between empathy and aggression.

Secret to raising well behaved teens? Maximize their zzzzz's Posted: 26 Sep 2014 05:58 AM PDT While American pediatricians warn sleep deprivation can stack the deck against teenagers, a new study reveals youth's irritability and laziness aren't down to attitude problems but lack of sleep. This paper exposes the negative consequences of sleep deprivation caused by early school bells, and shows that altering education times not only perks up teens' mood, but also enhances learning and health.

Skin pigment renders sun's UV radiation harmless using projectiles Posted: 26 Sep 2014 05:58 AM PDT The pigment of the skin protects the body from the sun's dangerous UV rays, but researchers have not until recently known how this works. Now they report that skin pigment converts the UV radiation into heat through a rapid chemical reaction that shoots protons from the molecules of the pigment.

More than 70% of young oncologists in Europe suffer symptoms of burnout Posted: 26 Sep 2014 05:55 AM PDT Across Europe, more than 70% of young cancer specialists are showing signs of burnout, the largest survey of its kind has revealed. The results have prompted calls for serious action to address the issue at all levels. Burnout could lead to serious personal consequences for the doctor such as anxiety, depression, alcohol or substance abuse and suicide, researchers warned.

Protein 'map' could lead to potent new cancer drugs Posted: 26 Sep 2014 05:55 AM PDT Chemists have gained fresh insights into how a disease-causing enzyme makes changes to proteins and how it can be stopped. The scientists hope their findings will help them to design drugs that could target the enzyme, known as N-myristoyltransferase (NMT), and potentially lead to new treatments for cancer and inflammatory conditions.

Experts call for moratorium on use of new internet domain .health Posted: 25 Sep 2014 05:58 PM PDT As the Internet Corporation for Assigned Names and Numbers moves forward with plans to launch health-related generic top-level domains, such as .health and .doctor, a coalition of health policy academics and clinicians are raising concerns about a process they say 'favor[s] business interests and the generation of profits over the future integrity of the Health Internet.'

Turmeric compound boosts regeneration of brain stem cells Posted: 25 Sep 2014 05:58 PM PDT A bioactive compound found in turmeric promotes stem cell proliferation and differentiation in the brain, reveals new research. The findings suggest aromatic turmerone could be a future drug candidate for treating neurological disorders, such as stroke and Alzheimer's disease.

Talk therapy – not medication – best for social anxiety disorder, large study finds Posted: 25 Sep 2014 05:56 PM PDT While antidepressants are the most commonly used treatment for social anxiety disorder, new research suggests that cognitive behavioral therapy is more effective and, unlike medication, can have lasting effects long after treatment has stopped.

Sand dunes reveal biodiversity secrets in Australia Posted: 25 Sep 2014 03:27 PM PDT Ancient, acidic and nutrient-depleted dunes in Western Australia are not an obvious place to answer a question that has vexed tropical biologists for decades. But the Jurien Bay dunes proved to be the perfect site to unravel why plant diversity varies from place to place. Scientists show that environmental filtering -- but not a host of other theories -- determines local plant diversity in one of Earth's biodiversity hotspots.
