Origin of the unique ventilatory apparatus of turtles: How the tortoise's ribs got embedded in its shell Posted: 07 Nov 2014 08:10 AM PST Through the careful study of modern and early fossil tortoise, researchers now have a better understanding of how tortoises breathe and the evolutionary processes that helped shape their unique breathing apparatus and tortoise shell.

Maybe it wasn't the Higgs particle after all Posted: 07 Nov 2014 08:10 AM PST Last year CERN announced the finding of a new elementary particle, the Higgs particle. But maybe it wasn't the Higgs particle, maybe it just looks like it. And maybe it is not alone.

Brain's response to threat silenced when we are reminded of being loved and cared for Posted: 07 Nov 2014 08:10 AM PST Being shown pictures of others being loved and cared for reduces the brain's response to threat, new research has found. The study discovered that when individuals are briefly presented pictures of others receiving emotional support and affection, the brain's threat monitor, the amygdala, subsequently does not respond to images showing threatening facial expressions or words. This occurred even if the person was not paying attention to the content of the first pictures.

Scientists examine mysterious tar mounds in the West African deep ocean Posted: 07 Nov 2014 06:15 AM PST More than two thousand mounds of asphalt harboring a wealth of deep-water creatures have been discovered up to two kilometers deep, off the coast of Angola. Scientists have been examining the images and data captured at the site to build an intriguing picture of the life and geology of this underwater area. The naturally-occurring asphalt mounds are made up of the same substance that covers our roads.

Hungry bats compete for prey by jamming sonar Posted: 06 Nov 2014 11:37 AM PST In their nightly forays, bats hunting for insects compete with as many as one million hungry roost-mates. Now scientists have discovered that Mexican free-tailed bats jam the sonar of competitors to gain advantage in aerial foraging contests.

Ancient DNA shows earliest European genomes weathered the Ice Age: Neanderthal interbreeding clues and a mystery human lineage Posted: 06 Nov 2014 11:37 AM PST A genome taken from a 36,000 skeleton reveals an early divergence of Eurasians once they had left Africa, and allows scientists to better assess the point at which 'admixture' -- or interbreeding -- between Eurasians and Neanderthals occurred. The latest research also points to a previously unknown population lineage as old as the first population separations since humans dispersed out of Africa.

Rare 2.5-billion-year-old rocks reveal hot spot of sulfur-breathing bacteria: Sulfur-dependent life forms thrived in oceans Posted: 06 Nov 2014 11:37 AM PST Biogeochemical signals in 2.5-billion-year-old carbonate rocks from Brazil reveal that sulfur-consuming bacteria were active at a time when ocean sulfur levels were low. Geologists focused on sulfur isotopes in ancient carbonate rocks. The study sheds light on Earth's early atmospheric chemistry.

Denying problems when we don't like the political solutions: Why conservatives, liberals disagree so vehemently Posted: 06 Nov 2014 10:23 AM PST There may be a scientific answer for why conservatives and liberals disagree so vehemently over the existence of issues like climate change and specific types of crime. A new study finds that people will evaluate scientific evidence based on whether they view its policy implications as politically desirable. If they don't, then they tend to deny the problem even exists.

Scientists create Parkinson's disease in a dish Posted: 06 Nov 2014 10:22 AM PST A team of scientists created a human stem cell disease model of Parkinson's disease in a dish. Studying a pair of identical twins, one affected and one unaffected with Parkinson's disease, another unrelated Parkinson's patient, and four healthy control subjects, the scientists were able to observe key features of the disease in the laboratory, specifically differences in the patients' neurons' ability to produce dopamine, the molecule that is deficient in Parkinson's disease.

New knowledge about human brain's plasticity Posted: 06 Nov 2014 10:18 AM PST The brain's plasticity and its adaptability to new situations do not function the way researchers previously thought, according to a new study. Earlier theories are based on laboratory animals, but now researchers have studied the human brain, and reached some new conclusions.

Ghost illusion created in the lab Posted: 06 Nov 2014 10:18 AM PST Patients suffering from neurological or psychiatric conditions have often reported 'feeling a presence' watching over them. Now, researchers have succeeded in recreating these ghostly illusions in the lab.

New research adds spice to curcumin's health-promoting benefits Posted: 06 Nov 2014 08:32 AM PST The health benefits of over-the-counter curcumin supplements might not get past your gut, but new research shows that a modified formulation of the spice releases its anti-inflammatory goodness throughout the body.

New bioenergetic organelle found in plants Posted: 06 Nov 2014 05:26 AM PST To date, it was thought that mitochondria and chloroplasts were the only plant cell components able to produce chemical energy. However, according to a new article, another organelle has been identified by researchers, the chromoplast, able to synthetize energy for its metabolism.

European satellite Gaia could discover thousands of planets in Milky Way galaxy Posted: 05 Nov 2014 05:35 PM PST A recently launched European satellite could reveal tens of thousands of new planets within the next few years, and provide scientists with a far better understanding of the number, variety and distribution of planets in our galaxy, according to researchers.

2,000-year-old youth organization Posted: 05 Nov 2014 05:47 AM PST In Roman Egypt, 14-year-old boys were enrolled in a youth organization in order to learn to be good citizens.
