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 / 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 ...
Phys.org / Research questions legitimacy of promoting harmful products
Marketers need to pay more attention to how marketing practices normalize the consumption of products that are known to be harmful to public health and social well-being, University of Otago—Ōtākou Whakaihu Waka researchers ...
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 ...
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 ...
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, ...
Tech Xplore / How electric vehicles could back up the power system
Electric vehicles (EVs) could do more for our environment than simply replace gasoline. Published in Joule, a new assessment of EV charging strategies suggests that EVs could serve as a vast network of mobile batteries, storing ...
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 ...
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 ...
Medical Xpress / How to enjoy Easter chocolate without wrecking your sleep
Easter is here and chocolate is everywhere—crowding shop shelves, piling up on desks, and likely already sitting in your pantry.
Phys.org / Software package makes gene regulation easier to study—and tweak
Understanding how genes are switched on and off in specific cell types remains one of biology's central challenges. While AI has made major progress in decoding the regulatory logic of DNA, applying these approaches across ...
