Phys.org / Surprising diversity found among Europe's last Neanderthals
A new study published in Nature provides the most detailed picture to date of Neanderthal diversity in Western Europe shortly before their extinction.
Medical Xpress / Blocking a female-only GABA signal that helps glioblastoma evade immunity may boost survival
Researchers have identified a critical biological difference in how glioblastoma develops in male and female laboratory models, pinpointing an immune pathway that fuels tumor growth only in females. The study shows that the ...
Phys.org / Chloroplast study reveals molecular lock that helps power life on Earth
A new study reveals the dynamics of photosynthesis at the cellular level. Led by co-authors Professor Barry Bruce and Associate Professor Rajan Lamichhane, both of the Department of Biochemistry and Cellular and Molecular ...
Phys.org / Moose are native to Colorado, study shows
The modern Colorado moose is often considered just that: modern—brought to the state by wildlife officials in the late 1970s, preceded by very occasional reports of moose sightings in the 19th and early 20th centuries.
Phys.org / Horizon edge states gain finite description in string theory calculation
Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a variety of cosmological and gravitational phenomena. Two renowned examples of these boundaries are ...
Phys.org / White barn owls may use moonlight to startle prey
White barn owls are effective killing machines. They fly silently through the night air and swoop down on unsuspecting prey with their sharp talons. But they have something you would think goes against being a stealth predator: ...
Phys.org / Why warmer seas may not wipe out female fish in some species
In many fish species, water temperature determines the sex of the fry. This biological mechanism threatens to wipe out entire populations because of a shortage of females in the face of global warming. However, an international ...
Phys.org / Brain growth may explain why birds lay outsized eggs compared with dinosaurs
A new study has uncovered a fundamental link between brain size and offspring size, helping to solve a long-standing evolutionary puzzle: Why do birds lay such disproportionately large eggs?
Phys.org / Plant protein pair reveals new wood-formation mechanism
Researchers from the Biosciences Department at Durham University have discovered a previously unknown mechanism that helps plants control the formation of wood, a finding that could open new directions for research into plant ...
Phys.org / This tiny Australian spider uses a high‑powered web catapult to trap and eat aggressive ants
There's more than one way a spider can spin its web. Some construct large vertical orb webs, while others build horizontal sheet webs or tangled cobwebs that ensnare crawling insects.
Medical Xpress / Lab-engineered proteins: A promising treatment for liver disease
The research group led by CIC biomaGUNE's Ikerbasque Research Professor Aitziber L. Cortajarena has developed an innovative anti-fibrotic and anti-tumor treatment by binding a synthetic protein to gold nanoclusters (small ...
Phys.org / Branched silver sensor offers more sensitive light-based drug measurements in blood plasma
Medications can save lives, yet for some drugs, the concentration in a patient's bloodstream determines whether a treatment is effective or whether harmful side effects may occur. Researchers at the Leibniz Institute of Photonic ...
