Phys.org / Tunas and other ocean predators may have evolved more slowly than previous research predicted
Today, oceans host a large variety of fast, resilient marine predators, including tunas, mackerels and various other fish species. Many of these fish belong to a lineage known as Scombridae, whose members are characterized ...
Medical Xpress / Breakdown of immune cells' interaction is key driver in aging, study finds
We may age at different rates, but none of us escapes aging. A study in mice and human cells by Stanford Medicine researchers pins much of the blame on a particular type of immune cell's increasing inability, with advancing ...
Tech Xplore / New contact material improves efficiency and stability of perovskite solar cells
A newly developed material for the electron contact improves the efficiency of single perovskite solar cells and perovskite/silicon tandem solar cells. The new material is based on a carborane molecule. It offers several ...
Phys.org / Air from Greenland snow shows industrialization's impact on atmospheric methane
An international team of researchers, including scientists from Utrecht University and the University of Maryland, has reconstructed the concentration of clumped isotopes of methane in air from the past for the first time. ...
Tech Xplore / New spinning drone hides in plain sight: 'Phantom Twist' harnesses motion blur to nearly vanish in flight
By exploiting the quirks of human vision, Northwestern University engineers have designed a drone that nearly disappears before the eyes. For years, researchers have tried to design invisible drones and robots using camouflage, ...
Tech Xplore / Fertilizer from the neighborhood: Where local ammonia plants make economic sense
Small-scale plants could produce ammonia directly where it is needed. A global analysis involving the Paul Scherrer Institute (PSI) shows where and under what conditions such mini-plants could operate in a low-carbon and ...
Medical Xpress / Facing funding losses, states call out big businesses with employees on Medicaid
As the Trump administration's January deadline looms for states to enforce new Medicaid work requirements, some state lawmakers are turning the tables by pushing to publicly name the largest companies that have employees ...
Medical Xpress / GLP-1 receptor agonist use does not increase insulin discontinuation with type 2 diabetes
For veterans with type 2 diabetes (T2D) receiving basal insulin therapy, the addition of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) does not increase the rate of insulin discontinuation compared with other glucose-lowering ...
Medical Xpress / Study finds mixed associations between breastfeeding and childhood allergies
Breastfeeding is widely recognized for its important role in supporting a child's early growth and immune system development. Previous studies have found that exclusive breastfeeding for 4 to 6 months is associated with a ...
Phys.org / For biodiversity to thrive across Europe, laws should treat wildlife as individuals capable of suffering, experts argue
Wildlife protection frameworks in both the EU and the UK need stronger and more consistent implementation—and must recognize animals as "individuals capable of experiencing suffering," rather than mere ecological assets.
Tech Xplore / Engineers shrink powerful terahertz systems onto a single semiconductor chip
High-frequency waves classified as terahertz occupy a relatively underused region of the electromagnetic spectrum between infrared light and microwaves. Researchers have long recognized their unique potential for applications ...
Medical Xpress / Are you listening to me? Well, kinda… Research shows people can track more than one conversation at once
Ever wondered how some people seem able to keep up with the conversation they're having while also noticing what's being said across the room? New research suggests this ability isn't simply good hearing but may reflect the ...
