A team of scientists has identified how a "sixth sense" in fish allows them to detect flows of water, which helps resolve a long-standing mystery about how these aquatic creatures respond to their environment. The work in Physical Review Letters illustrates how sensory systems evolve in accordance with physical principles while also offering a framework for understanding how sensory networks are structured.

In a new study, an analysis of 5,749 patients who received dalcetrapib or placebo and provided DNA in a clinical study found a strong association between the effects of dalcetrapib and a specific gene called ADCY9 (adenylate cyclase 9) on chromosome 16, particularly for a specific genetic variant (rs1967309).

In patients with the genetic profile AA at rs1967309, there was a 39% reduction in the composite cardiovascular endpoint with dalcetrapib compared to placebo. Supporting evidence was also obtained from a second study, which showed that patients with the favorable genetic profile also benefited from a reduction in the thickness of their carotid artery walls with dalcetrapib.  

Over 12 million Americans visit their doctors annually complaining of headaches and the real costs and estimates of lost productivity could be up to $31 billion annually.

What might help more people without spending more money? Fewer tests and some counseling about lifestyle changes.

As has been demonstrated, even after complete spinal paralysis the human spinal cord is able to trigger activity in the leg muscles using electrical pulses from an implanted stimulator.

Now a team of researchers has succeeded in identifying the mechanisms the spinal cord uses to control this muscle activity. These mechanisms still work even if the neural pathways from the brain are physically interrupted as the result of a spinal cord injury. It is the first time throughout the world that the spinal-cord activation patterns for walking have been decoded, say the authors of a new paper. 

Up to 10% of adults living in developed countries fish for food and recreation and a new paper finds that in the Mediterranean Sea that could be up to 10% of the total production of fisheries - a large amount that is basically un-regulated outside buying a license. 

A small pilot study has shown that most of the children in a new oral immunotherapy treatment program were able to eat 100 grams of wheat bread without side effects, a promising way to mitigate the risk of accidental ingestion by people with this allergy.
