Medical Xpress / Cannabis and tobacco use linked to smaller brain volume
Cannabis and tobacco—whether used on their own or together—can affect the brain's structure. A recent study involving systematic review and meta-analysis of more than 103 studies found that both substances are linked to reduced ...
Phys.org / Silicon quantum computer performs logical operations for the first time
Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, silicon's compatibility with existing chip technology and its long coherence times in silicon-based ...
Medical Xpress / How T cells amplify signals: New study reveals key molecular switch
Signaling is fundamental to how cells sense and respond to their environment—but in immune cells, those signals must be precisely amplified to mount an effective defense against invasive threats. New research by immunologists ...
Tech Xplore / Waste water to clean energy: Japanese engineers harness the power of osmosis
A Japanese water plant is harnessing the natural process of osmosis to generate renewable energy that could one day become a common power source.
Medical Xpress / How the human brain builds our sense of time
How does Jannik Sinner manage to hit the ball at exactly the right moment, with remarkable precision? And how do we, in everyday life, perceive the duration of events around us? The answer lies in how the brain constructs ...
Phys.org / Exposing secret night operations between hawkmoths and Japan's black-nectar flowers
Researchers Soma Chiyoda, Ko Mochizuki, and Atsushi Kawakita from the University of Tokyo have discovered that nocturnal hawkmoths are the main pollinators of Jasminanthes mucronata, a plant species native to Japan that produces ...
Phys.org / AI writes a research paper that passes peer review
To date, the main role of AI in scientific research has been to assist with narrow tasks such as discovering chemical structures, analyzing data or predicting protein shapes. But now, the technology has broken new ground ...
Phys.org / New study pinpoints climate conditions for restoring the endangered butternut tree
The butternut tree, a close relative of black walnut prized for its pale wood and wildlife value, is on the brink of disappearing from North American forests. A new study from Virginia Tech offers hope that the species could ...
Phys.org / 3D root model captures mangroves' capacity to protect coastal communities from storm waves
Mangrove forests are natural wonders that protect coastal areas, particularly in tropical and subtropical regions. They are able to dissipate wave energy and limit flooding, which can even mitigate tsunamis and coastal inundations ...
Phys.org / Gaia analysis finds Messier 35 is larger and older than earlier estimates
Astronomers from Egypt and Turkey have conducted a comprehensive analysis of kinematic, structural, and astrophysical parameters of a nearby open cluster known as NGC 2168. Results of the new study, published March 23 on ...
Phys.org / Can unpaved roads and watersheds co-exist? Researchers wade into the question
Imagine a dump truck dropping 13 tons of dirt into the waters of Brush Creek, a waterway that feeds northwest Arkansas' primary drinking water source, Beaver Lake. That's how much soil and sediment researchers measured going ...
Phys.org / New catalyst enables targeted antibiotic redesign to beat resistant bacteria
Antibiotics, our infantry against bacteria, are losing their ability to fight against bacterial infections due to the rise of superbugs—microbes that have developed resistance to medications that are designed to kill them. ...
