But researchers captured the first photo of a planet in the making, a planet residing in a gap in LkCa15's disk. Of the roughly 2,000 known exoplanets, only about 10 have been imaged -- and long after they had formed, not when they were in the making. Results were published in Nature. |

| Scientists turn tastes on and off by activating and silencing clusters of brain cells Posted: 18 Nov 2015 12:51 PM PST Most people probably think that we perceive the five basic tastes -- sweet, sour, salty, bitter and umami (savory)--with our tongue, which then sends signals to our brain 'telling' us what we've tasted. However, scientists have turned this idea on its head, demonstrating in mice the ability to change the way something tastes by manipulating groups of cells in the brain. |
| Low-oxygen 'dead zones' in North Pacific linked to past ocean-warming events Posted: 18 Nov 2015 12:51 PM PST A new study has found a link between abrupt ocean warming at the end of the last ice age and the sudden onset of low-oxygen, or hypoxic conditions that led to vast marine dead zones. |

Though naturally regulated in a healthy organism, heparanase is an enzyme which is produced in excessive quantities in a cancer situation. |
| When did the Andes mountains form? Posted: 18 Nov 2015 10:18 AM PST The Andes were formed by tectonic activity whereby Earth is uplifted as one plate (oceanic crust) subducts under another plate (continental crust). To get such a high mountain chain in a subduction zone setting is unusual, which adds to the importance of trying to figure out when and how it happened. However, the timing of when the Andean mountain chain uplift occurred has been a topic of some controversy over the past ten years. Now, new research shows that the Andes have been a mountain chain for much longer than previously thought. |
| Ecological extinction explains how turbulence dies Posted: 18 Nov 2015 10:18 AM PST Physicists have developed a theoretical understanding of laminar-turbulent transition that explains the lifetime of turbulent flows and an unexpected analogy with the behavior of an ecosystem on the edge of extinction. This could lead to an improved understanding of how the onset of turbulence can be controlled, potentially reducing energy costs in oil pipelines. It may also have implications for cardiovascular medicine, perhaps reducing the risk of aneurysms. |

| New guidelines on the prevention/control of multi-drug-resistant gram-negative bacteria Posted: 18 Nov 2015 10:10 AM PST Gram-negative bacteria include common types such as E. coli that all of us carry in our bowels. When these bacteria get into other parts of the body they can cause infections, including common infections such as cystitis or urinary tract infections. The bacteria can also be readily spread from person to person. Multi-drug-resistant strains are resistant to most, or all, of the common antibiotics that we use to treat infections. New accredited guidelines on the prevention and control of multi-drug-resistant Gram-negative bacteria have now been released. |

| How 'deviant' messages flood social media Posted: 18 Nov 2015 06:43 AM PST From terrorist propaganda distributed by organizations such as ISIS, to political activism, diverse voices now use social media as their major public platform. Organizations deploy bots — virtual, automated posters — as well as enormous paid "armies" of human posters or trolls, and hacking schemes to overwhelmingly infiltrate the public platform with their message. A professor of information science has been awarded a grant to continue his research that will provide an in-depth understanding of the major propagators of viral, insidious content and the methods that make them successful. |

| Rheumatologist suggests number one arthritis drug is underutilized, underdosed Posted: 18 Nov 2015 06:43 AM PST Physicians are underutilizing methotrexate, the leading drug for rheumatoid arthritis (RA), or not keeping patients on the drug long enough before switching them to more expensive biologic drug options, one expert suggests. |
| Why mice have longer sperm than elephants Posted: 18 Nov 2015 04:14 AM PST In the animal world, if several males mate with the same female, their sperm compete to fertilize her limited supply of eggs. Longer sperm often seem to have a competitive advantage. However, a study now reveals that the size of the animals also matters. The larger the animal, the more important the number of sperm is relative to sperm length. That's why elephants have smaller sperm than mice. |
| New options for treating autism Posted: 18 Nov 2015 04:13 AM PST The operating mechanism of oxytocin, the molecule involved in social behavior, has been researched by a team of European scientists. The results obtained in the research suggest that one of the mechanisms by which oxytocin causes interpersonal relations to be perceived as pleasant could be through the release of anandamide. |
| Economic significance of cities increases while that of countries falls Posted: 18 Nov 2015 04:13 AM PST According to a European study, the most competitive cities are those with greater economic and political leadership and innovative activity. |
| Use your loaf to save British wildlife Posted: 18 Nov 2015 04:13 AM PST Farmers can maintain high yields and boost nature by signing up to a wildlife-friendly scheme, new research suggests. The research suggests that some government schemes designed to encourage farmers to help wildlife have had limited effectiveness. The results support the need for more targeted government schemes and for consumers to support farmers and brands that are wildlife-friendly. |
