11,500-year-old animal bones in Jordan suggest early dogs helped humans hunt Posted: 15 Jan 2019 10:29 AM PST 11,500 years ago in what is now northeast Jordan, people began to live alongside dogs and may also have used them for hunting, a new study shows. The archaeologists suggest that the introduction of dogs as hunting aids may explain the dramatic increase of hares and other small prey in the archaeological remains at the site. |
New effect in the interaction of plasmas with solids discovered Posted: 15 Jan 2019 10:28 AM PST If a plasma comes in contact with a solid, under certain circumstances the surface is changed fundamentally and permanently. Researchers have now discovered a surprising effect, in which the electronic properties of the solid material, such as its electrical conductivity, can be changed in a controlled, extremely fast and reversible manner, by ion impact. |
Power stations driven by light Posted: 15 Jan 2019 10:28 AM PST The smallest building blocks within the power stations of organisms which get their energy directly from the sun are basically miniature reactors surrounded by collectors which capture photons and forward them to the center. The close correlation between structure and interaction of the components boosts productivity, a strategy which researchers are using for increasing the efficiency of solar technology. |

How Candida albicans exploits lack of oxygen to cause disease Posted: 15 Jan 2019 10:28 AM PST Scientists have shown how the yeast Candida albicans can modulate and adapt to low oxygen levels in different body niches to cause infection and to harm the host. Studying adaption to hypoxic or anoxic niches is particularly fruitful, since it helps us to understand the pathogenicity of C. albicans and promotes the development of better therapy approaches. |

Effects of linoleic acid on inflammatory response depend on genes Posted: 15 Jan 2019 09:45 AM PST The effects of linoleic acid on the human body are largely dependent on genes, a new study shows. Linoleic acid is an essential fatty acid. People carrying different variants of the FADS1 gene had a different inflammatory response and different changes in their fasting glucose levels when supplementing their diet by linoleic acid rich sunflower oil. This was the first time these associations were studied in humans. |
Mathematical model can improve our knowledge on cancer Posted: 15 Jan 2019 09:44 AM PST Researchers have developed a new mathematical tool, which can improve our understanding of what happens when cells lose their polarity (direction) in diseases such as cancer. The result is advancing our understanding of how the fertilized egg cell develops into a complete organism. Biological shapes, like individual organs or an entire body, can be reproduced or maintained with great accuracy, just like in the embryonic development or during the adult stage. |

Genes reveal clues about people's potential life expectancy Posted: 15 Jan 2019 09:44 AM PST Scientists say they can predict whether a person can expect to live longer or die sooner than average, by looking at their DNA. Experts have analyzed the combined effect of genetic variations that influence lifespan to produce a scoring system. People who score in the top ten per cent of the population might expect to live up to five years longer than those who score in the lowest ten per cent, they say. |
Using satellites to measure rates of ice mass loss in glaciers Posted: 15 Jan 2019 09:44 AM PST Researchers have investigated all glacial areas in South America in more detail than ever before, from the tropical areas to the subpolar regions. Their two major findings are that the highest rate of mass loss is in the Patagonian ice sheet, and that the glaciers in the tropics have lost considerably less mass than previously projected, although this is not the good news which it might appear at first sight. |

Bike share programs show infrequent helmet use, little disparity among neighborhoods Posted: 15 Jan 2019 09:11 AM PST People riding free-floating bike share rentals in Seattle are wearing helmets infrequently, according to a new analysis. Only 20 percent of bike share riders wore helmets in the study, while more than 90 percent of cyclists wore helmets while riding their own bikes. Different research on the free-floating bike share systems showed that bikes were usually available in all Seattle neighborhoods across economic, racial and ethnic lines. However, more bikes were located in more-advantaged neighborhoods. |
B-group vitamins can improve concentration among people with first episode psychosis Posted: 15 Jan 2019 09:11 AM PST A new study explored the impact of increasing a person's intake of vitamins B12, B6, and folic acid [vitamin B9] after studies in people with schizophrenia revealed that increased intake of these vitamins could decrease patients' levels of an amino acid called homocysteine and improve their symptoms. |
Dissidents under authoritarian rule: Staying anonymous yet trustworthy Posted: 15 Jan 2019 09:11 AM PST Minority and dissident communities face a perplexing challenge in countries with authoritarian governments. They need to remain anonymous to avoid persecution, but also must establish a trustworthy identity in their communications. An interdisciplinary group of researchers has designed an application to meet both of these requirements. |

MANF identified as a rejuvenating factor in parabiosis Posted: 15 Jan 2019 09:11 AM PST Older mice who are surgically joined with young mice in order to share a common bloodstream get stronger and healthier, making parabiosis one of the hottest topics in age research. Researchers now report that MANF (mesencephalic astrocyte-derived neurotrophic factor) is one of the factors responsible for rejuvenating the transfused older mice. Researchers also show the naturally occurring, evolutionarily conserved repair mechanism protects against liver damage in aging mice and extends lifespan in flies. |
