| Scientists prevent preterm birth caused by gene-environment interactions in mice Posted: 27 Aug 2013 09:28 AM PDT New research provides evidence that gene-environment interactions are a major contributor to preterm birth and that using a combinatory treatment strategy can prevent preterm delivery in a mouse model. Scientists say their study provides important new insights into a major global health problem -- one that remains stubbornly persistent in the United States.  |
| Researcher controls colleague's motions in first human brain-to-brain interface Posted: 27 Aug 2013 09:27 AM PDT Researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher.  |
| How quickly can a bacterium grow? E. coli can replicate close to thermodynamic limits of efficiency Posted: 27 Aug 2013 08:30 AM PDT All living things must obey the laws of physics -- including the second law of thermodynamics, which states that the universe's disorder, or entropy, can only grow. Highly ordered cells and organisms appear to contradict this principle, but they actually do conform because they generate heat that increases the universe's overall entropy.  |
| European hunter-gatherers owned pigs as early as 4600 BC Posted: 27 Aug 2013 08:30 AM PDT European hunter-gatherers acquired domesticated pigs from nearby farmers as early as 4600 BC, according to new evidence. The international team of scientists showed there was interaction between the hunter-gatherer and farming communities and a 'sharing' of animals and knowledge. The interaction between the two groups eventually led to the hunter-gatherers incorporating farming and breeding of livestock into their culture, say the scientists.  |
| Existence of new element confirmed Posted: 27 Aug 2013 06:16 AM PDT An international team of researchers has confirmed the existence of what is considered a new element with atomic number 115. The experiment was conducted at the GSI research facility in Germany. The results confirm earlier measurements performed by research groups in Russia.  |
| Long-term memory stored in the cortex Posted: 27 Aug 2013 06:16 AM PDT 'Where' and 'how' memories are encoded in a nervous system is one of the most challenging questions in biological research. The formation and recall of associative memories is essential for an independent life. The hippocampus has long been considered a centre in the brain for the long-term storage of spatial associations. Now, researchers have provided the first experimental evidence that a specific form of memory associations is encoded in the cerebral cortex and is not localized in the hippocampus as described in most neuroscience textbooks. The new study is a game changer since it strongly suggests that the motor cortical circuits itself, and not the hippocampus, is used as memory storage.  |
| Posted: 27 Aug 2013 06:14 AM PDT The nature of the teenage brain makes users of cannabis amongst this population particularly at risk of developing addictive behaviors and suffering other long-term negative effects, according to researchers who reviewed over 120 studies.  |
| Scientists detect magmatic water on moon's surface Posted: 27 Aug 2013 06:13 AM PDT Scientists have detected magmatic water — water that originates from deep within the Moon's interior — on the surface of the Moon. These findings represent the first such remote detection of this type of lunar water.  |
| Structure of chromosomes supported by a kind of molecular skeleton Posted: 26 Aug 2013 06:58 AM PDT Scientists have found that the structure of chromosomes is supported by a kind of molecular skeleton, made of cohesin.  |
