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.
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.
For centuries drought has come and gone across northern sub-Saharan Africa. In recent years, water shortages have been most severe in the Sahel—a band of semi-arid land situated just south of the Sahara Desert and stretching coast-to-coast across the continent, from Senegal and Mauritania in the west to Sudan and Eritrea in the east. Drought struck the Sahel most recently in 2012, triggering food shortages for millions of people due to crop failure and soaring food prices.
The U.S. Fish & Wildlife Service has placed the rusty patched bumble bee, once common in 28 states and two Canadian provinces, on the endangered species list, the first bee to receive such protection in the contiguous 48 states.
With 2016 reportedly the warmest year on record, scientists have discovered insects are already feeling the effects of climate change, as a rise in temperature is shown to damage their ability to reproduce.
The global climate is a complex machine in which some pieces are separate yet others are connected. Scientists try to discover the connections to predict what will happen to our climate, especially in a future with more heat-trapping gases.
