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.
Phys.org / Iberian DNA remained largely unchanged for six centuries before Roman influence, study finds
A study led by a UAB research team of Biological Anthropology has analyzed the genome of 54 newborns with the aim of tracking the genetic history of their culture since it developed in the Early Iron Age until the start of ...
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 / Chimpanzees react negatively to unfairness, especially when close partners are nearby
Primates, including humans, are among the social animals living on Earth. Their survival relies heavily on cooperation with others, alliances, the sharing of resources and other social interactions.
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 ...
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 / Can AI help coastal cities prepare for rising seas and extreme events?
Our novel artificial intelligence model can predict extreme storm surges with high accuracy, including under future climate conditions. Because the AI model runs much faster, it can help researchers and practitioners better ...
Phys.org / Tabletop experiment helps reconcile fundamental physics
Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and her colleagues show how a tabletop experiment can bring together two bedrock physics theories that ...
Phys.org / Space telescopes are now overwhelmed by satellite trails
Unfortunately, there's more bad news to report on the clear skies front. A new paper, available on the arXiv preprint server from researchers at NASA's Ames Research Center, reports that 73.3% of images the agency's new SPHEREx ...
Phys.org / Infrastructure for African mines destroying forests at 34 times the rate of the mines themselves
Industrial-scale mining in Africa to support global supply chains is leading to unprecedented deforestation across the continent, with 34 hectares of forest removed for every single hectare of active mine site.
Phys.org / Is your dog a lefty? New 'Doginburgh' test captures paw preference
Just like left- or right-handed humans, domestic dogs have a preference for their left or right paw, a trait known as laterality. This can vary depending on the tasks they perform, which has made it difficult to create a ...
Phys.org / New art test could help museums spot fake Van Goghs without touching paintings
A new study published in the peer-reviewed journal Surface Topography: Metrology and Properties introduces a pioneering, noninvasive technique that can distinguish authentic artworks from forgeries, offering museums, collectors, ...
