Medical Xpress / Cell-free DNA offers early warning for bloodstream infections in kids with leukemia
Researchers have identified a promising way to predict bloodstream infections in children with high-risk leukemia days before the infection would be diagnosed using current standards of care. The test, named plasma microbial ...
Phys.org / Are these killer whales cannibals? They probably don't think so themselves
In 2022, a Russian whale researcher made a remarkable discovery on Bering Island off Russia's Pacific coast: a severed killer whale fin marked with the teeth of another killer whale. In 2024, it happened again. The two finds ...
Phys.org / A computer simulation is helping to prepare Australia for H5 bird flu
Currently, Australia is the only continent in the world still free from the highly contagious H5 bird flu. But that status faces an ongoing threat.
Phys.org / Limiting global warming can reduce US wildfire smoke-related deaths by thousands annually
Using future climate scenarios based on wildfire damages in North America, scientists estimate that up to 10,000 or more lives may be saved annually in the United States if society is able to mitigate climate change by keeping ...
Phys.org / How to train your catalyst, one atom at a time
How do you keep a copper catalyst from losing its oomph? Just add a dusting of platinum, says a new study published in Nature Materials. A team of researchers, including scientists at the Department of Energy's SLAC National ...
Phys.org / NASA's MAVEN detects first evidence of lightning-like activity on Mars
While sifting through the extensive data collected by NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft over the last decade, scientists discovered a familiar type of electromagnetic signal commonly caused ...
Medical Xpress / Breast cancer still most common cancer among women worldwide, with annual cases expected to exceed 3.5 million by 2050
Despite recent advancements in breast cancer treatments, new breast cancer cases in women are predicted to rise by a third globally from 2.3 million in 2023 to more than 3.5 million in 2050. Similarly, yearly deaths from ...
Phys.org / Chemists create complex DNA structures without hydrogen bonds
No "sticky ends"? No problem. A new study by NYU chemists finds that DNA tiles can assemble into 3D structures without the sticky cohesion of hydrogen bonding. This finding, published in Nature Communications, turns a fundamental ...
Medical Xpress / Molecular defect in taste cells causes long-term taste loss after COVID
Scientists have identified molecular and structural changes in taste buds that may explain why a small subset of people experience long-term taste loss after COVID-19 infection. The study, published in Chemical Senses, provides ...
Phys.org / Porpoises can 'turn down the volume' to withstand ship noise
Porpoises are entirely dependent on their hearing for survival. They navigate, hunt, and communicate by emitting rapid click sounds and listening to the returning echoes. However, with increasingly noisy oceans, it is getting ...
Tech Xplore / AI often escalates to nuclear action in war games
There are some things perhaps we might not want artificial intelligence to handle, at least for the time being. When leading chatbots were put through war-game simulations, they opted for nuclear signaling or escalation in ...
Phys.org / Greenhouse gas fluxes in Everglades provide path for maximizing carbon capture via water management
The Florida Everglades is a complicated climate actor. The 1.5-million-acre wetland system remains a carbon sink, removing an average of 13.7 million metric tons of carbon dioxide from the atmosphere each year, but the system ...
