New AI tool illuminates 'dark side' of the human genome
31 July 2025 @ 11:00 pm
Proteins sustain life as we know it, serving many important structural and functional roles throughout the body. But these large molecules have cast a long shadow over a smaller subclass of proteins called microproteins.
How harmful content is evading detection on popular video gaming sites
31 July 2025 @ 9:00 pm
New research published in the journal Frontiers in Psychology reveals how extremist groups are exploiting the popularity of video games to recruit and radicalize impressionable users.
In Darwin's wake: Two-year global conservation voyage sparks hope
31 July 2025 @ 8:30 pm
After a two-year around-the-world ocean voyage inspired by Charles Darwin, scientists and crew sailed home on a historic vessel into Rotterdam Thursday bearing a warning about climate change—but also a message of hope.
Simulations reveal surprising electron temperatures near M87 black hole's event horizon
31 July 2025 @ 8:20 pm
The first black hole images stunned the world in 2019, with headlines announcing evidence of a glowing doughnut-shaped object from the center of galaxy Messier 87 (M87 —55 million light years from Earth. Supercomputer simulations are now helping scientists sharpen their understanding about the environment beyond a black hole's 'shadow,' material just outside its event horizon.
Russian space chief says agreed with NASA on ISS cooperation until 2028

The head of Russia's space agency Roscosmos said Thursday that he had agreed with his NASA counterpart during talks in the United States to extend the International Space Station's (ISS) operation until 2028.
Government to keep sharing key satellite data for hurricane forecasting despite planned cutoff
31 July 2025 @ 8:10 pm
The U.S. Department of Defense will now continue sharing key data collected by three weather satellites that help forecasters track hurricanes. Meteorologists and scientists had warned of risks to accurate and timely storm tracking without the information when officials made plans to stop providing it beyond the end of this month.
South Africa starts injecting rhino horns with radioactive material to curb poaching
31 July 2025 @ 8:06 pm
A South African university launched an anti-poaching campaign Thursday to inject the horns of rhinos with radioactive isotopes that it says are harmless for the animals but which can be detected by customs agents.
New work sheds light on the survival strategies of parasite responsible for Leishmaniasis
31 July 2025 @ 7:57 pm
Leishmaniasis is a parasitic disease that affects up to 1 million people worldwide each year. It is caused by the protozoan Leishmania, transmitted through the bite of a sandfly. Once inside its host—human or animal—the parasite settles in immune cells called macrophages and multiplies within small bubble-like structures known as parasitophorous vacuoles.
Microrobots that can carry drugs and steer could provide targeted drug delivery
31 July 2025 @ 7:57 pm
Microrobots formed in droplets could enable precision-targeted drug delivery, improving on I.V. drug delivery that sends only 0.7% of the drug to the target tissue, according to a recent study in Science Advances, conducted through simulations at the University of Michigan and experiments at the University of Oxford.
Scientists create first programmable single-atom catalyst that adapts chemical activity
31 July 2025 @ 7:56 pm
A research team at the Politecnico di Milano has developed an innovative single-atom catalyst capable of selectively adapting its chemical activity. This is a crucial step forward in sustainable chemistry and the design of more efficient and programmable industrial processes.
