Phys.org / Backyard birdwatchers help scientists uncover what hawks really like to eat
Anyone who keeps a bird feeder has likely had the same uneasy thought after seeing a sudden blur of wings in the yard: What was that hawk doing here?
Phys.org / Graphene 'nano-aquariums' capture atomic-resolution videos of gold atoms in solvents
A team led by scientists at the National Graphene Institute (NGI) at The University of Manchester has developed the first technique capable of capturing atomic‑resolution videos of individual gold atoms 'dancing' across a ...
Medical Xpress / Uncontrolled scarring: Study reveals the cell sensor that turns healing into harm
Fibrosis is the body's way of patching up damage—a bit like fixing a pothole. When skin is cut or a muscle is injured, fibroblast cells rush in to make fibronectin and collagen, which are two major extracellular matrix proteins ...
Phys.org / Archival records reveal prevalence of sexually transmitted infections during Otago's gold rush less than purported
Sexually transmitted infections in Otago's gold rush era were less common than popular culture books portray, University of Otago—Ōtākou Whakaihu Waka research has found. The first-of-its-kind study, published in the Journal ...
Phys.org / Frequent prescribed burns help young oaks thrive despite invasive grasses, study finds
As winter comes to a close, many people look forward to warmer temperatures and spring blooms, but for land managers working to preserve or restore oak-dominated forests, it is prescribed burn season. Fire brings more light ...
Medical Xpress / Proof of visual perception's fundamental mechanisms: 1981 Nobel Prize-winning model confirmed correct
A scientific dispute spanning six decades about fundamental mechanisms of visual perception in mammals has now been settled. Researchers at TUM have succeeded in observing the visual information flow from neuron to neuron. ...
Tech Xplore / New AI testing method flags fairness risks in autonomous systems
Artificial intelligence is increasingly being used to help optimize decision-making in high-stakes settings. For instance, an autonomous system can identify a power distribution strategy that minimizes costs while keeping ...
Medical Xpress / Sugary drink taxes are not effective in fast-food settings, drive-through analysis suggests
Taxes on sugary drinks had no effect on beverage calorie purchases from fast-food chain restaurants in the U.S., according to a new study by Brian Elbel and Pasquale Rummo from NYU Grossman School of Medicine and colleagues ...
Phys.org / Male fish lose their learning edge in drug-polluted waters, research reveals
A common antidepressant detected in rivers and streams worldwide is disrupting how fish learn, and the impact is strikingly one-sided. New research led by Monash University shows the drug amitriptyline impairs spatial learning ...
Medical Xpress / How pancreatic tumors thwart an iron-driven demise
Tumors driven by cancer-driving KRAS mutations are often susceptible to ferroptosis, a type of cell death that can be harnessed for cancer therapy. Given that more than 95% of pancreatic ductal adenocarcinomas (PDACs) harbor ...
Tech Xplore / Air-powered artificial muscles could help robots lift 100 times their weight
Researchers at Arizona State University are developing bio-inspired robotic "muscles" that will enable robots to operate in boiling water, survive abrasive surfaces, bypass impediments that keep their motorized counterparts ...
Phys.org / Watering smarter, not more: A modern-day robotic divining rod
Advanced technology can help farmers get to the root of a growing problem—overwatering in an era of increasing drought and water scarcity. A new UC Riverside system can map soil moisture tree by tree, so growers water only ...
