A group of studies says that salmon raised in man-made hatcheries can harm wild salmon through competition for food and habitat. Salmon, which survived millions of years of evolution, are in danger from...salmon.

The studies provide new evidence that fast-growing hatchery fish compete with wild fish for food and habitat in the ocean as well as in the rivers where they return to spawn and even raises questions about whether the ocean can supply enough food to support future increases in hatchery fish while still sustaining wild salmon. 

Things would seem to be good in China.  They are the only world economy not in a financial demilitarized zone, things are booming.  

Yet more money is not making people there happier. They're actually less happy today than shortly after the Tiananmen Square protest in Beijing was crushed by the military, says economist Richard Easterlin, researcher in "happiness economics" and namesake of the Easterlin Paradox.

Researchers  have uncovered a new way to stimulate activity of immune cell opiate receptors, leading to efficient tumor cell clearance - their pharmacological approach can activate the immune cells to prevent cancer growth through stimulation of the opiate receptors found on immune cells.

Understanding neurons - their shape, patterns of electrical activity even a profile of which genes are turned on at a given moment - remains as much art as science due to the complexity of research.

But that could soon change: Researchers at MIT and the Georgia Institute of Technology have developed a way to automate the process of finding and recording information from neurons in the living brain. The researchers have shown that a robotic arm guided by a cell-detecting computer algorithm can identify and record from neurons in the living mouse brain with better accuracy and speed than a human experimenter.

A 1.5 metric ton block of engraved limestone at the Abri Castanet in southern France is the earliest evidence of wall art - approximately 37,000 years old and evidence of the role art played in the daily lives of Early Aurignacian humans. 

The research team has been excavating at Abri Castanet for the past 15 years. Abri Castanet and its sister site Abri Blanchard are among the oldest sites in Eurasia bearing artifacts of human symbolism. Hundreds of personal ornaments have been discovered, including pierced animal teeth, pierced shells, ivory and soapstone beads, engravings, and paintings on limestone slabs.

Your cay may soon have a new dashboard, one made of a flexible plastic and oxide layer that could be integrated into the car front window to give the driver direct information

The MULTIFLEXIOXIDES project is designed to develop new cost-efficient, long lasting, light, flexible and transparent devices (can anything be all of those?  Only in academia) which can display information directly on the windshield. This is possible using small glass pads with a transparent substrate of nano-sized flexible oxides, which act as a basis for organic LEDs (light-emitting diodes).
