Study: Social media doesn't always bring people together, even when they have shared goals for democracy

University of Kansas
Peer-Reviewed Publication

Researchers from the University of Kansas interviewed women who took part in Algeria's 2019 "Hirak" protests. They reported experiencing misogyny and intimidation on social media from groups who were protesting the same cause. The findings suggest social media's touted ability to bring disparate groups together around a common cause may not be as powerful as commonly thought.

Patients’ affinity for AI messages drops if they know the technology was used

Duke University Medical Center
Peer-Reviewed Publication

In a Duke Health-led survey, patients who were shown messages written either by artificial intelligence (AI) or human clinicians indicated a preference for responses drafted by AI over a human. That preference was diminished, though not erased, when told AI was involved.

New method uses DNA barcodes for high throughput RNA and protein detection in deep tissue

Howard Hughes Medical Institute
Peer-Reviewed Publication

An innovative new technique developed at HHMI's Janelia Research Campus uses a novel DNA barcode system to track hundreds of RNA and protein molecules in single cells within thick biological samples, providing researchers with a full picture of how these structures are organized inside tissues.

Water movement on surfaces makes more electric charge than expected

RMIT University
Peer-Reviewed Publication

Researchers in Australia have discovered that water generates an electrical charge up to 10 times greater than previously understood when it moves across a surface.

The team observed when a water droplet became stuck on a tiny bump or rough spot, the force built up until it “jumped or slipped” past an obstacle, creating an irreversible charge that had not been reported before.

The new understanding of this phenomenon paves the way for surface design with controlled electrification, with potential applications ranging from improving safety in fuel-holding systems to boosting energy storage and charging rates.

Rising CO2 levels: Impacts on crop nutrition and global food supplies

Higher Education Press
Peer-Reviewed Publication

A new study published in Engineering uncovers the dual-faced effects of elevated CO₂ on food security. It shows that while elevated CO₂ can bring certain benefits to plants, it also poses threats such as reducing nutrient content in crops, which may impact global food supplies and human health.
