Urine tests confirm alcohol consumption in wild African chimpanzees‎

Aleksey Maro knows far more than he cares to know about the urination habits of chimpanzees. But if you want to measure the alcohol intake of chimps in a Ugandan rain forest, where a breathalyzer is impractical, collecting urine for analysis is your only choice.

Human activity is making the Arctic's waters louder‎

Climate change is having a profound impact on the Arctic. We know that the region is warming significantly faster than the global average, resulting in the melting of sea ice and disrupted habitats.

Quantum effect could power the next generation of battery-free devices‎

A new study has revealed how tiny imperfections and vibrations inside a promising quantum material could be used to control an unusual quantum effect, opening new possibilities for smaller, faster, and more efficient energy-harvesting devices.

New Aegean index unlocks advance in Mediterranean seasonal rainfall forecasting‎

A new study has identified a distinct climate precursor in the Mediterranean Sea that can predict winter precipitation levels in the Levant months in advance. The study, published in Weather and Climate Dynamics, is titled "Mediterranean Sea heat uptake variability as a precursor to winter precipitation in the Levant."

How studying yeast in the gut could lead to new, better drugs‎

A new study sheds light on the behavior of yeast cells in the gut, paving the way for new lines of yeast that more efficiently produce therapeutic drugs tailored to address specific diseases. The research is published in the journal BMC Genomics.

Why do microbes team up? A new model explains nutrient sharing in fluctuating environments‎

Depending on others for something you need may feel like a risky proposition—and perhaps a human one. It is actually a survival strategy found in the microbial world, and far more frequently than one might expect. Discovering why is key to understanding how microbes form stable communities across medical, industrial, and ecological settings.

Synthetic RNA 'nanostars' create programmable compartments in bacteria‎

Researchers at the Department of Chemical Engineering and Biotechnology (CEB) have found a new way to organize molecules inside living cells, opening possibilities for more controlled and efficient biomanufacturing. The team has published a paper in Nature Communications demonstrating that engineered RNA molecules can self-assemble into membraneless organelles inside Escherichia coli (E. coli).

The hidden stress facing coral reef fish in the Arabian Gulf‎

A new study from NYU Abu Dhabi has found that small coral reef fish in the Arabian Gulf are facing a hidden but growing source of stress. When oxygen levels drop at night, a common occurrence on some of the world's hottest reefs, these fish must use extra energy just to recover the next day. Over time, this additional strain could impact their growth, survival, and the overall balance of reef ecosystems.

Targeted climate policies are successfully cutting carbon, study shows‎

Countries with stricter and better-targeted climate policies cut carbon emissions faster, according to a major new study by researchers in the UK and EU. The study draws on the most comprehensive climate policy dataset ever assembled, using over 3,900 policies adopted since 2000 in 43 leading economies responsible for well over three quarters of global emissions. The findings are published in the journal Nature Communications.

Physicists develop new method to measure universe's expansion rate‎

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These methods are internally consistent and based on the same physics, so all observed values of the Hubble constant should agree. But those that come from early-universe datasets disagree with those that come from late-universe datasets. This problem is known as the Hubble tension and is considered to be one of the most significant open questions in cosmology.
