Geologists identify deep-earth structures that may signal hidden metal lodes

Scientists have discovered previously unrecognized structural lines 100 miles or more down in the earth that appear to signal the locations of giant deposits of copper, lead, zinc and other vital metals lying close enough to the surface to be mined, but too far down to be found using current exploration methods.

Spider silk can create lenses useful for biological imaging

Spider silk is useful for a variety of biomedical applications: It exhibits mechanical properties superior to synthetic fibers for tissue engineering, and it is not toxic or harmful to living cells. One unexpected application for spider silk is its use in the creation of biocompatible lenses for biological imaging applications. Researchers now describe the feasibility of creating lenses capitalizing on the properties of natural spider silk material.

Astronomers have now detected a system of super-Earth planets orbiting the nearby star Gliese 887, the brightest red dwarf star in the sky. The newly discovered super-Earths lie close to the red dwarf's habitable zone, where water can exist in liquid form.

Unexpected mental illnesses found in a spectrum of a rare genetic disorder

Researchers found an unexpected spectrum of mental illnesses in patients with a rare gene mutation. These patients had a ''double hit'' condition that combined features and symptoms of fragile X syndrome and premutation disorder, in addition to a range of psychiatric symptoms. The findings revealed the need for clinicians to consider the complexities of the co-existing conditions of patients with both psychological and fragile X associated disorders.

Sugary drink tax models show health gains, cost reductions, but vary by tax design

A simulation model details how different taxing strategies for sodas and other sugary drinks could impact health gains linked to heart attacks, strokes and diabetes while also lowering health care costs in the US. Three types of taxation on sugary drinks lower healthcare costs, cardiovascular disease, and diabetes, but some -- such as taxing sugar content -- perform even better than taxing based on the volume of the beverage.

A new social role for echolocation in bats that hunt together

To find prey in the dark, bats use echolocation. Some species, like Molossus molossus, may also search within hearing distance of their echolocating group members, sharing information about where food patches are located. Social information encoded in their echolocation calls may facilitate this foraging strategy that allows them to find food faster.
