Phys.org / AI model 'hears' Bryde's whale calls in seismic data from South China Sea
Researchers have repurposed an AI model designed for visual identification tasks to detect Bryde's whale calls contained within seismic data collected in the South China Sea. The detection system precisely identified calls ...
Medical Xpress / Human-caused warming linked to childhood stunting across Africa
In 2022, about 149 million children younger than 5 worldwide suffered from childhood stunting. A critical marker of chronic undernutrition, stunting is more than a metric of physical height. It represents a lifelong constraint ...
Phys.org / Human evolution was messy and gradual, not an abrupt revolution, argues archaeologist
It is generally accepted by archaeologists that modern humans originated in Africa and dispersed worldwide, while other hominins went extinct. Yet how and when Homo sapiens dispersed out of Africa, and whether it was an abrupt ...
Phys.org / How ice-age sea-level falls may have turned seafloor volcanoes into ocean fertilizer
Ice-age sea-level declines may have turned seafloor volcanoes into natural iron fertilizer for plankton, potentially enhancing ocean carbon storage, Boston College researchers report in the journal Nature Geoscience.
Medical Xpress / Sleep and exercise may curb heart risk from mutant white blood cells
Healthy sleep and regular exercise can work to counteract genetic mutations in white blood cells that are associated with cardiovascular disease and are most common among older people, Mount Sinai researchers have found. ...
Tech Xplore / Russian satellites linked to mysterious GPS disruptions across several countries
Since 2019, GPS signals across Europe, Greenland and Canada have experienced a huge spike in sudden, widespread signal blackouts. These have resulted in disruptions and degraded performance in navigation systems that airplanes ...
Phys.org / 'Cool Routes' finds cooler walking paths with hourly forecasts and street-level shade data
The Arizona sunshine hits like a blowtorch. The pavement radiates heat like a stove burner. To make hot-weather walking less of an ordeal, Arizona State University researchers have created a web-based app that finds the coolest, ...
Medical Xpress / CRISPR enzyme precisely detects and shreds DNA in cancer mutations once considered 'undruggable'
In 2020, Jennifer Doudna won the Nobel Prize in chemistry for her work on the CRISPR-Cas9 gene-editing technology that allows scientists to precisely modify DNA by cutting it at specific locations. Six years later, a new ...
Phys.org / Gorillas can learn to trust humans even after years of poaching pressure, research shows
A new study led by Concordia researchers suggests that carefully habituating wild gorillas to nonthreatening humans can help the animals overcome long-term aversions to people in areas with a history of human-led disturbances ...
Phys.org / 'Black hole stars'—Webb finds strongest evidence yet
The complex puzzle known as little red dots has become more complete since their initial discovery by NASA's James Webb Space Telescope in 2022. Now a particular little red dot's spectrum is helping connect many of the pieces.
Medical Xpress / Ten-week therapy empowers parents to solve severe selective eating in children with autism
Picky eating is a challenge most parents are familiar with, but for parents of autistic children, severe selective eating can lead to nutritional deficiencies and place tremendous stress on the family. However, a new study ...
Phys.org / How bacteria organize themselves to 'hitchhike' across large distances
While scientists have studied how bacteria move toward food using a chemical radar known as chemotaxis, they have only watched single species swim in isolated environments over distances of only a few centimeters.
