| Posted: 07 Oct 2013 01:24 PM PDT Cloud-chamber experiments show that clouds on Mars form in much more humid conditions than clouds on Earth.  |
| Wedded bliss or blues? Scientists link DNA to marital satisfaction Posted: 07 Oct 2013 01:24 PM PDT What makes some people more prone to wedded bliss or sorrow than others? Researchers have found a major clue in our DNA. A gene involved in the regulation of serotonin can predict how much our emotions affect our relationships, according to a new study that may be the first to link genetics, emotions, and marital satisfaction.  |
| Delayed aging is better investment than cancer, heart disease Posted: 07 Oct 2013 01:23 PM PDT Research to delay aging and the infirmities of old age would have better population health and economic returns than advances in individual fatal diseases such as cancer or heart disease, reveals a new study.  |
| Study shows how neurons enable us to know smells we like and dislike, whether to approach or retreat Posted: 07 Oct 2013 12:17 PM PDT What underlying biological mechanisms account for our seemingly instant, almost unconscious ability to determine how attractive (or repulsive) a particular smell is? New research reveals a set of cells in the fruit fly brain that respond specifically to food odors. The degree to which these neurons respond when the fly is presented different food odors predicts "incredibly well how much the flies will 'like' a given odor."  |
| Plastic waste is a hazard for subalpine lakes, too Posted: 07 Oct 2013 09:25 AM PDT Many subalpine lakes may look beautiful and even pristine, but new evidence suggests they may also be contaminated with potentially hazardous plastics. Researchers say those tiny microplastics are likely finding their way into the food web through a wide range of freshwater invertebrates too. The findings, based on studies of Italy's Lake Garda and reported on October 7th in Current Biology, suggest that the problem of plastic pollution isn't limited to the ocean.  |
| Posted: 07 Oct 2013 07:26 AM PDT The Nobel Assembly at Karolinska Institutet has decided to award The 2013 Nobel Prize in Physiology or Medicine jointly to James E. Rothman, Randy W. Schekman and Thomas C. Südhof for their discoveries of machinery regulating vesicle traffic, a major transport system in our cells.  |
| Extrusive volcanism formed the Hawaiian Islands Posted: 07 Oct 2013 06:45 AM PDT A recent study changes the understanding of how the Hawaiian Islands formed. Scientists have determined that it is the eruptions of lava on the surface, extrusion, which grow Hawaiian volcanoes, rather than internal emplacement of magma, as was previously thought.  |
| Exceptional fossil fish reveals new evolutionary mechanism for body elongation Posted: 07 Oct 2013 06:40 AM PDT Snake and eel bodies are elongated, slender and flexible in all three dimensions. This striking body plan has evolved many times independently in the more than 500 million years of vertebrate animals history. Based on the current state of knowledge, the extreme elongation of the body axis occurred in one of two ways: either through the elongation of the individual vertebrae of the vertebral column, which thus became longer, or through the development of additional vertebrae and associated muscle segments.  |
| Drowsy Drosophila shed light on sleep and hunger Posted: 03 Oct 2013 09:13 AM PDT Sleep, hunger and metabolism are closely related, but scientists are still struggling to understand how they interact. Now, researchers have discovered a key function in a molecule in fruit flies that may provide insight into the complicated relationship between sleep and food.  |
