Migrating animals' pee affects ocean chemistry

Researchers found that migrating animals release ammonia, which plays a significant role in shaping marine chemistry, particularly in low-oxygen zones. The study reveals that animal behavior on a large scale influences the ocean's chemistry, with implications for predicting ocean changes under climate change.

Scientists discover a 'good' fat that fights diabetes

Researchers have discovered a new class of lipids in humans called fatty acid hydroxy fatty acids (FAHFAs) that are linked to reduced inflammation and improved blood sugar levels in diabetes. FAHFA levels are low in humans with a high risk for diabetes, suggesting potential therapeutic opportunities for metabolic disorders.

'Superglue' for the atmosphere

Researchers at Goethe University Frankfurt found that dimethylamine can greatly enhance the formation of aerosol particles from sulfuric acid, creating 'neutral molecular cluster' formations. This process could influence Earth's climate by affecting cloud condensation nuclei and precipitation patterns.

Of bio-hairpins and polymer-spaghetti

The study reveals that biopolymer filaments undergo a transition from entangled spaghetti-like structures to aligned bow-shaped filaments when in flow, leading to dramatic shear-thinning behavior. This finding may aid the search for renewable alternatives and provide insights into biological processes such as cytoplasmic flow.

Space-based methane maps find largest US signal in Southwest

A new study by the University of Michigan and NASA reveals that the Four Corners region in the US Southwest has the largest methane signal seen from space, with over half a teragram emitted annually. The research uses satellite data to identify the source of the emissions, which are likely caused by infrastructure and coalbed methane.

Multiple neurodevelopmental disorders have a common molecular cause

A study reveals that distinct genetic mutations in neurodevelopmental disorders produce similar molecular effects, suggesting a one-size-fits-all therapeutic approach may be effective for conditions like seizures and ADHD. The research identifies shared molecular pathways involved in these diseases, providing new insights into their ca...

Universal screening for MRSA may be too costly

Researchers found that universal MRSA screening and isolation can prevent nearly three hospital-acquired MRSA infections but come with a high cost. Targeted screenings for high-risk patients also showed limited success in preventing infections while resulting in financial losses.

Zeroing in on a source of gamma rays

A team of researchers, led by Michigan State University astronomer Laura Chomiuk, has discovered the location where a nova explosion emitted gamma rays. Using highly detailed radio telescope images, they pinpointed the source to a stellar explosion, which may be common in other nova explosions.

Managers can boost creativity by 'empowering leadership' and earning employees' trust

Researchers found that empowering leaders can foster creativity in employees with high uncertainty avoidance and trust. Managers should focus on developing affect-based trust before empowering their team members. By establishing these conditions, managers can create an environment that encourages employee creativity.

Media celebrate female NFL referee, but fumble deeper issues

A study by Penn State researcher Dunja Antunovic found that the media mostly celebrated female NFL referee Shannon Eastin's debut, but failed to provide comprehensive analysis of gender issues in sports. The research highlights structural barriers that hinder women's participation in traditionally male roles.
