Phys.org / Dogs may use blinking as a subtle social signal
Blinking keeps eyes moist, sweeps away bits of dirt and dust, and helps the brain rest when processing visual information. But in dogs, it may also serve another function as a subtle social signal. That was one of the conclusions ...
Phys.org / Researchers reveal the unique 'tagging' mechanism that guides the sleeping brain in remembering key thoughts
Why do we remember certain moments while forgetting others? Every day, our minds are bombarded with thousands of pieces of information, yet our brains have a limited capacity to consolidate these experiences into lasting ...
Phys.org / XY or ZW? Gecko chromosomes reveal evolution's hidden playbook
Why do humans rely on XY chromosomes to determine sex, while birds use ZW—and many reptiles use neither, letting temperature decide instead? Sex determination is remarkably diverse across the animal kingdom. In genotypic ...
Medical Xpress / Unexpected discovery reveals mechanism behind brain tumor development
When researchers at Lund University investigated how UM171, a molecule used to make blood stem cells multiply, works, they made an unexpected connection. The results provide new insights into how one of the most common malignant ...
Phys.org / How bacteria develop resistance to programmable antibiotics
Antimicrobial resistance is one of the greatest challenges facing modern medicine. A new class of programmable antibiotics known as asobiotics can be used to treat bacterial infections when classical antibiotics fail. A team ...
Tech Xplore / Nanoscale transistors achieve lower contact resistance with stepwise evaporation method
Metals, semiconductors and insulators are fundamental components of modern electronics. However, efforts to improve device performance have largely focused on semiconductor quality, while metal crystallinity has received ...
Phys.org / Thermal anomaly discovered below Mars' south pole
Researchers have discovered a thermal asymmetry deep beneath the surface across Mars' southern hemisphere. Based on gravitational measurements that provide clues to the Red Planet's interior structure, Mars' southern interior ...
Phys.org / Hyperdoped silicon photodiode advances short-wave infrared detection at room temperature
Detecting short-wave infrared (SWIR) light, a region of the electromagnetic spectrum just beyond the light visible to the human eye, could be advantageous for many real-world applications. For instance, it could enable more ...
Phys.org / Unexpected source of genetic diversity found in human sperm
Scientists have identified an unexpected source of genetic variation in human sperm that occurs earlier in sperm development than previously thought. Published in Nature, researchers at the Wellcome Sanger Institute, the ...
Phys.org / Oxygen collisions reveal how quark–gluon matter approaches equilibrium
High-energy nuclear collisions recreate extreme conditions similar to those in the early universe, producing quark–gluon plasma (QGP), a hot state of matter in which quarks and gluons are no longer confined inside protons ...
Phys.org / The wisdom of the egg cell: Oocyte epigenetic mark may help prevent excessive placental growth after fertilization
The genome—which contains genes encoded in DNA—acts as the fundamental blueprint of life. But what you might not know is that, in addition to this genetic information, we have something akin to an "instruction manual" for ...
Phys.org / 'Mad honey' that can stop your heart is now being sold online worldwide
A few months ago, a friend of mine told me that his father-in-law had been rushed to the hospital after eating some wild honey brought back from the hills of Nepal.
