Phys.org / No brain required: This is how the single-celled Stentor learns
Scientists have known for more than a century that a single-celled organism with no nerve cells—much less a brain—can behave in ways that resemble learning. But those observations only went so far. How the organism did that ...
Phys.org / 'Ruthless predator' of red tide plankton reveals unusual bioluminescence
Scientists at UC San Diego's Scripps Institution of Oceanography have uncovered new insights into the bioluminescence of a unique species of marine plankton that feeds on other plankton, including the harmful algae responsible ...
Medical Xpress / Validation study reveals new tool can predict patients' genetic risk of 8 cardiovascular conditions
Researchers at Mass General Brigham Heart and Vascular Institute and collaborators have developed and validated a new genetic risk test that can estimate a person's inherited risk for eight common cardiovascular conditions, ...
Medical Xpress / Optimizing exercise and nutrition before surgery boosts patient outcomes, review finds
Providing patients with structured exercise and nutrition support before surgery can reduce complications and shorten hospital stays, according to a new review published in the Journal of the American College of Surgeons ...
Phys.org / Exploring representation through digital archaeology and game design
Recently, Michael Hall, a doctoral candidate in the Comparative Literature and Cultural Studies Program, was invited to present his work exploring representation in gaming, "Dawnbreaker, the Curious Case of Decolonialism ...
Phys.org / New study details changing US irrigated agriculture, viability strategies
A new study by researchers at the Daugherty Water for Food Global Institute at the University of Nebraska offers a comprehensive national-scale assessment of irrigated agriculture in the United States in recent years. Published ...
Medical Xpress / Americans support cannabis rescheduling, study finds
Most people strongly support the federal government's reclassification of cannabis, according to a new study that used AI to analyze more than 40,000 comments in the public record. The findings by researchers at Johns Hopkins ...
Phys.org / Levitated nano-ferromagnet confirms a 160-year-old physical prediction
Ferromagnets, such as iron, cobalt, and nickel, are materials with a strong, spontaneous, and permanent magnetic field. Over 150 years ago, the physicist and mathematician James Clerk Maxwell speculated that under specific ...
Phys.org / Newly confirmed supernova remnant is one of the faintest ever detected
An international team of astronomers reports the discovery of a new supernova remnant (SNR) using radio observations. The newfound supernova remnant, dubbed Abeona, is one of the faintest radio SNRs so far detected. The discovery ...
Medical Xpress / Glioblastoma mapping uncovers four recurring tumor cell communities, revealing treatment targets
Glioblastoma (GBM) is an aggressive type of brain cancer that is known to be very difficult to treat. One reason why this type of cancer is often resistant to available treatments is that it is characterized by a highly diverse ...
Science X / For centuries these dazzling Roman bowls were misread—until chemical traces exposed an unexpected maker
For centuries, archaeologists debated the origins of Rome's exquisite mosaic-glass bowls. Now, chemical fingerprints in 101 ancient shards point to a surprising center of production: Italy, not Egypt. This discovery challenges ...
Tech Xplore / Brain-inspired approach can teach AI to doubt itself just enough to avoid overconfidence
Most contemporary artificial intelligence (AI) systems learn to complete tasks via machine learning and deep learning. Machine learning is a computational approach that allows models to uncover patterns in data that are useful ...
