Timing of turkey nesting may not shift with changing climate
2023-07-13
A new study suggests eastern wild turkeys in five southern U.S. states are unlikely to make meaningful changes in the timing of when they begin nesting, even under significant future climate change.
The findings suggest eastern wild turkeys (Meleagris gallopavo silvestris) could be vulnerable to shifts in climate, which could threaten the availability of their food sources, the amount of vegetation cover available to protect them from predators, and other factors.
“There are implications here for turkey populations ...
New toxin facilitates disease infection and spread in wheat
2023-07-13
Although wheat was among the first domesticated food crops, it remains a global dietary staple several millennia later. Grown on every continent except Antarctica, wheat is the second highest produced grain worldwide, with nearly 800,000 metric tons grown each year (Food and Agriculture Organization). However, a fungal pathogen named Fusarium graminearum causes the devastating disease Fusarium head blight (FHB) on wheat and contaminates grains with harmful toxins called trichothecenes. One such trichothecene, called deoxynivalenol (DON), is produced by most F. graminearum strains in the United States, and it is an essential virulence factor that increases the pathogen’s spread ...
FAU receives $11.5 million gift to combat life-threating illness, amyloidosis
2023-07-13
Currently, there is no cure for amyloidosis, a life-threatening disease that can be present throughout the body, including the heart, kidneys, liver and brain. The most common localized form of amyloidosis, which is seen significantly more often, is in the brain. Cerebral amyloidosis, when symptomatic, usually manifests in one of two ways: in Alzheimer’s disease and related dementias and in brain bleeds, which have consequences such as a stroke.
Because amyloidosis does not affect a specific organ, unraveling the underlying cause of amyloid fibril creation – a hallmark ...

Fear is in the eye of the beholder
2023-07-13
Averting our eyes from things that scare us may be due to a specific cluster of neurons in a visual region of the brain, according to new research at the University of Tokyo. Researchers found that in fruit fly brains, these neurons release a chemical called tachykinin which appears to control the fly’s movement to avoid facing a potential threat. Fruit fly brains can offer a useful analogy for larger mammals, so this research may help us better understand our own human reactions to scary situations and phobias. Next, the team want to find out how these ...
Multiple ecosystems in hot water after marine heatwave surges across the Pacific
2023-07-13
(Santa Barbara, Calif.) – Rising ocean temperatures are sweeping the seas, breaking records and creating problematic conditions for marine life. Unlike heatwaves on land, periods of abrupt ocean warming can surge for months or years. Around the world these ‘marine heatwaves’ have led to mass species mortality and displacement events, economic declines and habitat loss. New research reveals that even areas of the ocean protected from fishing are still vulnerable to these extreme events fueled by climate change.
A study published today in Global Change Biology, led by researchers at UC Santa ...
