Phys.org / 'Selection shadow' may explain why longer lives bring more age-related disease
A review article now published in Nature Reviews Genetics brings together evolutionary theory, comparative genomics and large-scale human genetics to explain why we age and why aging rates differ among individuals and species. ...
Phys.org / Genomes from Oceania offer new clues to human evolution
A new Yale-led study provides one of the most detailed and comprehensive analyses to date of genetic variation in human populations in Oceania, filling a major gap in representation in genomics research. Despite harboring ...
Phys.org / First global map of mycorrhizal fungi reveals true scale of underground networks across the planet
Mycorrhizal fungi form underground networks that sustain plant life and help regulate Earth's climate by drawing carbon into soils. In a study published in Science, an international team of researchers produced the first ...
Phys.org / Rare deep-sea goblin sharks filmed in natural habitat for first time
The first published live observations of the rare goblin shark (Mitsukurina owstoni) in its natural deep-ocean habitat were reported in a new paper by a University of Hawai'i at Mānoa-led team of oceanographers. In the past, ...
Phys.org / Cosmic dawn fuel discovery unlocks early galaxy growth secrets
Astronomers have discovered a huge reservoir of cold molecular gas, the direct fuel for star formation, in REBELS-25, a massive, star-forming galaxy. The team, led from Leiden University, focused on REBELS-25, seen when the ...
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 / Wasp spider reveals rapid genetic adaptation during decades-long march into northern Europe
It has taken only a few decades: The wasp spider (Argiope bruennichi) has expanded its range from the Mediterranean region to northern Europe—even as far as southern Finland. In doing so, it has adapted genetically much faster ...
Phys.org / Light echoes reveal possible dark matter buildup around supermassive black holes
We may not know what dark matter is, but we keep getting whiffs of it. "We are reaching a point where the observational evidence for dark matter is simply undeniable," said Mayank Sharma, a Virginia Tech graduate student ...
Phys.org / First leather bag made from T-Rex cells fails to sell at Paris auction
A leather bag made from Tyrannosaurus rex cells failed to sell Thursday, the Paris auction house Drouot said, commenting that bids were well below expectations.
Phys.org / Quantum friction causes light to slow down nanoworld movements
A research team in Bochum, Germany has unexpectedly found that light can slow down movements in the nanoworld. This is due to quantum friction, a phenomenon that has been poorly understood until now. The findings are published ...
Phys.org / A new kind of entanglement helps quantum sensors tune out noise
In a quest to build the most accurate quantum sensors in the world, scientists are constantly improving their performance, making them more precise, more stable and more reliable. But eventually, physical constraints will ...
