Salmon are severely impacted by the loss of floodplain habitats near Oregon's Tillamook Bay, where nearly 90 percent of estuaries' tidal wetlands have been lost to development -- threatening the survival of coho salmon and the safety of the local community. Now, the Federal Emergency Management Agency, NOAA Fisheries, and others have come together to reduce flood risk, increase resiliency of the ecosystem, and restore salmon habitat in Tillamook Bay under the auspices of The Southern Flow Corridor project, as the proposed collaborative effort is known. It will reconnect over 500 acres of floodplain habitat to two of the Bay's most productive salmon-bearing streams -- the Wilson and Trask Rivers.

Children are more likely to have a repeat, delayed anaphylactic reaction from the same allergic cause, depending on the severity of the initial reaction. 

Anaphylaxis is a severe, allergic reaction that is rapid in onset and can result in death. Some children are at risk of delayed ('biphasic') anaphylactic reactions. Delayed reactions occur when the initial symptoms of allergic reaction go away but then return hours or days later without exposure to the initial substance that caused the reaction.

Researchers have successfully stopped cocaine and alcohol addiction in experiments using a drug already approved by the U.S. Food and Drug Administration (FDA) to treat high blood pressure. If the treatment is proven effective in humans, it would be the first of its kind -- one that could help prevent relapses by erasing the unconscious memories that underlie addiction.

Scientists once believed that drug addiction was simply a physical craving: Drug addicts who became sober and then later relapsed merely lacked willpower. But that view has gradually shifted since the 1970s.

A new test can accurately predict within minutes if an individual has Ebola  and is the first to show that a point-of-care EVD test is faster than and as sensitive as a conventional laboratory-based molecular method used for clinical testing during the recent outbreak in Sierra Leone.

This new rapid diagnostic test could cut back on the lengthy process usually required to confirm if a patient has Ebola, help identify case contacts, and ultimately curb the spread.

Are some people unable or unwilling to quit?  A popular sociological belief has been that by making smoking uncool or difficult, it will become unpopular and people will quit, and only those unable to quit would remain. If so, products like e-cigarettes or smokeless tobacco make sense as alternatives.

Scientists at St. Jude Children's Research Hospital have discovered how an immune system protein, called AIM2 (Absent in Melanoma 2), plays a role in determining the aggressiveness of colon cancer. They found that AIM2 deficiency causes uncontrolled proliferation of intestinal cells. Surprisingly, they also discovered that AIM2 influences the microbiota -- the population of gut bacteria -- apparently fostering the proliferation of 'good' bacteria that can protect against colon cancer.

The team, led by Thirumala-Devi Kanneganti, Ph.D., a member of the St. Jude Department of Immunology, said that the findings could have important applications for prevention, prognosis and treatment.
