You can pretty much put a mark in your calendar for when the annual flu epidemic begins. Using 20,000 virus samples and weather statistics, researchers have now discovered more details about how outdoor temperature and flu outbreaks are linked.

Scientists at the Luxembourg Centre for Systems Biomedicine (LCSB) of the University of Luxembourg have identified a gene that may provide a new starting point for developing treatments for Alzheimer’s disease (AD). The USP9 gene has an indirect influence on the so-called tau protein, which is believed to play a significant role in the onset of Alzheimer’s disease.

Last year will be remembered as warmer than average for much of the nation, and depending on where you live, 2016 was either parched, soggy — or both.

Hazardous levels of domoic acid, a natural toxin that accumulates in shellfish, have been linked to warmer ocean conditions in waters off Oregon and Washington for the first time by a NOAA-supported research team, led by Oregon State University scientists.

Domoic acid, produced by certain types of marine algae, can accumulate in shellfish, fish and other marine animals. Consuming enough of the toxin can be harmful or even fatal. Public health agencies and seafood managers closely monitor toxin levels and impose harvest closures where necessary to ensure that seafood remains safe to eat. NOAA is supporting research and new tools to help seafood industry managers stay ahead of harmful algae events that are increasing in frequency, intensity and scope.

Predicting how species will respond to climate change is a critical part of efforts to prevent widespread climate-driven extinction, or to predict its consequences for ecosystems.
