Kissing helps us find the right partner – and keep them
Posted: 10 Oct 2013 05:51 PM PDT
What's in a kiss? A new study suggests kissing helps us size up potential partners and, once in a relationship, may be a way of getting a partner to stick around. 'Kissing in human sexual relationships is incredibly prevalent in various forms across just about every society and culture,' says one of the researchers. 'Kissing is seen in our closest primate relatives, chimps and bonobos, but it is much less intense and less commonly used.
Analysis of herbal products shows contamination is common
Posted: 10 Oct 2013 05:51 PM PDT
Most herbal products, available to buy as alternative medicines, may be contaminated. Researchers demonstrate the presence of contamination and substitution of plant species in a selection of herbal products using DNA barcoding.
Brain mechanisms behind a debilitating sleep disorder
Posted: 10 Oct 2013 11:29 AM PDT
Cataplexy is characterized by muscle paralysis during cognitive awareness. Until now, researchers have not understood this condition well. Now research has shown that the neuro-degeneration of the brain cells that synthesize the chemical hypocretin causes the noradrenaline system to malfunction. When the norandrenaline system stops working properly, it fails to keep the motor and cognitive systems coupled. This results in cataplexy -- the muscles fall asleep but the brain stays awake.
Complex relationship between phosphorus levels, nitrogen removal in lakes
Posted: 10 Oct 2013 11:29 AM PDT
In the land of 10,000 lakes, one lake has been the starting place for research with implications for big lakes around the world. Building from studies of nitrogen levels in Lake Superior, the new research uncovered a good news/bad news scenario for lake health that has long-term, global implications for pollution control efforts.
New antiviral response discovered in mammals
Posted: 10 Oct 2013 11:27 AM PDT
Researchers have discovered a part of the innate immune system in mice that had only been known in plants and invertebrates. This system seems more visible in stem and progenitor cells, which it protects from viral infection.
Newly discovered gene regulator could precisely target sickle cell disease
Posted: 10 Oct 2013 11:27 AM PDT
A research team has discovered a new genetic target for potential therapy of sickle cell disease. The target, called an enhancer, controls a molecular switch in red blood cells called BCL11A that, in turn, regulates hemoglobin production.
Iron in Earth's core weakens before melting
Posted: 10 Oct 2013 11:27 AM PDT
The iron in Earth's inner core weakens dramatically before it melts, explaining the unusual properties that exist in the moon-sized solid center of our planet that have, up until now, been difficult to understand.
One in five persons seeking pre-travel advice are high-risk travelers
Posted: 10 Oct 2013 11:27 AM PDT
Researchers have found that high-risk travelers account for nearly 20 percent of patients using the five clinics of the Boston Area Travel Medicine Network. The study also found that these travelers often visited destinations with malaria and typhoid risk.
Innate virus-killing power discovered in mammals
Posted: 10 Oct 2013 11:27 AM PDT
Scientists have a promising new approach to combating deadly human viruses thanks to an educated hunch by a microbiology professor, and his 20 years of research on plants, fruit flies, nematodes and mice. Researchers have discovered that, like plants and invertebrate animals, mammals use the RNA interference process to destroy viruses within their own cells. Until now, scientists were unable to prove that mammals use RNAi for killing viruses. The findings could help create vaccines against deadly infections, including SARS, West Nile, dengue, Hepatitis C and influenza.
Watery asteroid discovered in dying star points to habitable exoplanets
Posted: 10 Oct 2013 11:27 AM PDT
Latest research on rocky relics suggests a distant planetary system, now past its "death throes", had very similar water 'delivery system' to our own -- and consequently the potential to contain habitable exoplanets complete with water.
Water discovered in remnants of extrasolar rocky world orbiting white dwarf
Posted: 10 Oct 2013 11:27 AM PDT
Astrophysicists have found the first evidence of a water-rich rocky planetary body outside our solar system in its shattered remains orbiting a white dwarf.
Hunter-gatherers and immigrant farmers lived together for 2,000 years in Central Europe
Posted: 10 Oct 2013 11:27 AM PDT
Indigenous hunter-gatherers and immigrant farmers lived side-by-side for more than 2,000 years in Central Europe, before the hunter-gatherer communities died out or adopted the agricultural lifestyle.
Ancient DNA unravels Europe's genetic diversity
Posted: 10 Oct 2013 11:26 AM PDT
Ancient DNA recovered from a time series of skeletons in Germany spanning 4,000 years of prehistory has been used to reconstruct the first detailed genetic history of m
