Phys.org / Graphene 'scaffold' recruits bone cells and helps the body regenerate fractures
Experiments conducted in Brazil using laboratory rats have shown that graphene-based structures can act as a powerful ally in bone regeneration. These structures are made of sheets of the chemical element carbon that are ...
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. ...
Medical Xpress / Scientists uncover how the brain resolves emotional ambiguity
Scientists at the University of Oxford have demonstrated, for the first time, that a key emotional center deep in the human brain directly influences how we interpret ambiguous social cues. In a new study, published in Neuron, ...
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 ...
Medical Xpress / How disinfectants influence microbes across hospital rooms
Just because a topical antiseptic is swabbed on the skin doesn't mean it stays on the skin. In a new study, Northwestern University scientists studied how a powerful antiseptic, called chlorhexidine, affects bacteria in hospital ...
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 ...
Phys.org / New index reveals global water resources' growing dependence on extreme rainfall
As global temperatures climb, rainfall patterns are shifting in ways that could put water resources and agriculture under increasing strain, a new study published in Water Resources Research suggests.
Phys.org / How noise limits today's quantum circuits
Imagine you're trying to build a very long, complicated chain of dominoes. The aim is that each domino hits the next one perfectly, all the way down the line, producing an amazing result at the end. A quantum circuit is like ...
Phys.org / Astronomers determine the fate of a double white dwarf binary
Utilizing the stellar evolution code named Modules for Experiments in Stellar Astrophysics (MESA), Chinese astronomers have investigated the evolution of a recently discovered ultra-compact double white dwarf binary system ...
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 / Lost mosaic reveals first image of female beast-fighter from the Roman era
When you think of a fight between an animal and a human in ancient Roman sports, the mental image is usually of a big man vs. an animal in a big arena filled with cheering spectators. In a new study, Alfonso Manas, a researcher ...
Tech Xplore / Fair decisions, clear reasons: Creating fuzzy AI with fairness built in from the start
Although AI is not intentionally biased, it can inherit biases from the data fed into it, learning and repeating them until the system becomes inherently unfair. This is complicated by the problem of identifying where the ...
