IUPUI receives NSF grant to enhance geosciences education, expand community engagement

IUPUI has received a $428,000 NSF grant to develop a novel educational program that enhances geosciences education and inspires students to address community problems. The program will engage undergraduates from underrepresented groups and provide opportunities for them to explore environmental justice through a themed learning community.

Better sleep, less fear

A study by Itamar Lerner and colleagues found that higher quality sleep patterns are associated with reduced activity in brain regions involved in fear learning. The researchers suggest that baseline sleep quality may be a useful predictor of susceptibility to post-traumatic stress disorder (PTSD).

NUS researchers discover pathway by which blood cells release a potent signalling factor

Researchers at the National University of Singapore have discovered a critical molecular target for sphingosine-1-phosphate production, paving the way for regulating its signalling in circulation. Low levels of S1P have been linked to various immune and vascular diseases, including multiple sclerosis and cardiovascular complications.

Scientists identify 'first responders' to bacterial invasion

Researchers at KU Leuven have identified specific ion channels in airway cells that recognize lipopolysaccharide molecules from bacteria, triggering a rapid response mechanism against infections. This early defence mechanism is essential for combating bacterial invasion and could lead to the development of more effective treatments.

Air pollution cuts solar energy potential in China

Severe air pollution in northern and eastern China blocks about 20% of sunlight from reaching solar panels, significantly reducing solar energy production. The study found that aerosol pollution reduces the potential for solar electricity generation by as much as one and a half kilowatt-hour per square meter per day.
