Phys.org / Oak leaves harbor distinct microbial worlds on their opposite surfaces
A single leaf may look like a simple patch of green, but to the microscopic life that inhabits it, it is a vast landscape divided into different worlds.
Medical Xpress / Unexpected brain mechanism challenges assumptions about GLP-1s
For decades, obesity medications produced only modest weight loss. But in recent years, Ozempic and related GLP-1 therapies have transformed the field, enabling sustained weight loss of 10% to 15% or more. Despite their success, ...
Phys.org / Controlled cracking technique prints quantum dots into tiny pixels for sharper displays
Recent technological advances have enabled the development of increasingly sophisticated, sharper displays for electronic devices. Many modern displays use light-emitting diodes, or LEDs, tiny semiconductor-based components ...
Phys.org / DNA repair enzymes favor specific sequences, shaping mutation patterns in the human genome
When a wound does not heal properly, it leaves a scar. Similarly, mutations—which are permanent changes to genetic code—are often the result of damaged DNA that has not been properly repaired. Mutations can impede the function ...
Tech Xplore / New engineering studies aim to slow battery aging while idle
Most batteries spend more than 70% of their lifetime at rest. Yet few studies have examined calendar aging, which is how a battery degrades when it is neither charging nor being used.
Phys.org / Oldest known giant rock scallop bead suggests California coastal trade began millennia earlier
Archaeologists have discovered two giant rock scallop beads that push back the clock on the first appearance of these high-status ornaments. The discovery shows that these prized marine beads were traded hundreds of miles ...
Medical Xpress / Simple blood test on a chip could help diagnose lung cancer
Researchers at Tel Aviv University have developed a new method for diagnosing lung cancer: a simple, fast, low-cost blood test that does not require DNA sequencing. The method identifies a chemical fingerprint of cancer cells ...
Phys.org / Illegal fishing captures up to 15% of global marine wild catch, analysis finds
Industrial-scale illegal fishing continues to undermine ocean sustainability, coastal livelihoods and global seafood markets—despite decades of regulation and recent advances in surveillance technology, according to new University ...
Phys.org / MRI study shows dogs can distinguish between human fear and sadness
Scientists—and dog lovers—have long known that dogs are remarkably good at interpreting our laughs, frowns and tears. But the biology behind this ability has remained largely unexplored until now. In a study published in ...
Tech Xplore / How malicious SIM cards can hijack smartphones, EV chargers and connected devices
Subscriber Identity Modules (SIMs), secure elements used to connect devices to a mobile network, can pose severe security risks when compromised. A malicious SIM could allow attackers to gather information about a device, ...
Phys.org / Water quality, not just scarcity, may shape future competition for a limited resource
Climate change is largely to blame for water scarcity. The low water levels in European rivers this summer speak volumes in that respect.
Phys.org / Engineered enzymes forge carbon-carbon and carbon-nitrogen bonds with high selectivity
Researchers from the Manchester Institute of Biotechnology, including Dr. Zachary Birch-Price and professor Anthony Green, have developed a new family of engineered enzymes that can create several different types of chemical ...
