Wireless ingestible capsule detects 'Leaky Gut' in real-time

A team of researchers has developed an ingestible bioimpedance sensing device that continuously monitors gastrointestinal mucosal barrier integrity wirelessly. The device can detect subtle changes in mucosal permeability, a common feature in Inflammatory Bowel Disease (IBD), enabling early detection and improved diagnosis.

Dissociation is a coping mechanism impeding effective climate action

A study by Cambridge University Press found that collective dissociation prevents people from taking effective action against the climate emergency, exacerbating mental health issues such as depression and PTSD. Researchers recommend measures like community engagement, mental health support, and infrastructure improvement to combat dis...

Facebook is constantly experimenting on consumers — and even its creators don’t fully know how it works

Researchers found significant flaws in Facebook's A/B testing methods, which can lead to misleading conclusions about ad effectiveness. The complex algorithms used by social media platforms can micro-target individuals based on unobservable factors, making it difficult to determine the true impact of ads.

Researchers successfully prove the solution to Dudeney’s 120-year-old dissection puzzle

A team of researchers from Japan Advanced Institute of Science and Technology proved that Dudeney's original solution to the famous dissection problem is the optimal solution. They used a novel approach, including matching diagrams, to show that no dissection between an equilateral triangle and a square can be achieved with three or fe...

Post-Dobbs decision changes in obstetrics and gynecology clinical workforce in states with abortion restrictions

The Dobbs decision has been linked to moderate but significant decreases in obstetrics and gynecology practitioners in the most restrictive states compared to control states. Clinician migration is likely affecting reproductive care access, quality, and equity as abortion rights are increasingly decided at the state level

Next-gen indoor navigation: VLP/INS integration delivers robust localization in dynamic environments

A cutting-edge solution integrates Visible Light Positioning and Inertial Navigation Systems to tackle dynamic inclination changes and signal blockages. The tightly coupled system achieves impressive positioning accuracy of up to 10 cm and inclination precision within 1 degree.

Gut bacteria heal the colon

Researchers found that supplementing gut bacteria with Clostridium scindens can improve recovery from colonic injury and enhance regeneration of the gut lining. This approach targets the underlying issue: impaired ability of the gut to heal itself by restoring natural bile acid balance.

Amid politically divisive debate on role of U.S. police in violence against Black citizens, AI-aided study of local news finds media criticism of police has not risen or become more partisan over last decade

A recent study by Carnegie Mellon University researchers used AI language models and human readers to analyze 1.3 million news excerpts referencing the police in 10 US cities from 2013 to 2023. The study found that local media criticism of police has remained steady, with only small differences in coverage between conservative and libe...

The boundaries of drainage basins shifted faster during past episodes of climate change, according to a new theory by Ben-Gurion University geologists

Researchers have presented a unique time-dependent record of drainage divide migration rates, showing that episodes of rapid shift coincide with past climate changes in the Negev over the last 230,000 years. This discovery accelerates our understanding of how climate affects the Earth's surface.

Decoding the neural basis of affective empathy: how the brain feels others' pain

A study by Dr. Keum Sehoon's team identified key neural ensembles in the anterior cingulate cortex that encode empathic freezing, a behavioral response to witnessing distress in others. The researchers found that observing another's pain triggers activation in the ACC as if the observer were experiencing pain themselves.
