Medical Xpress / Cognition and consciousness arise from analog computations, says new theory
A new theory, published in The Journal of Neuroscience by three scientists at the Picower Institute for Learning and Memory at MIT, offers an explanation of how the brain produces cognition and consciousness: It uses traveling ...
Tech Xplore / Coconut-blend fuel vs. jet fuel: Engines can't tell the difference, but the environment can
With airlines and consumers increasingly concerned about carbon, nitrogen and hydrocarbon emissions, biofuels have emerged as a green alternative. Among these, those made from coconut oil are particularly attractive because ...
Medical Xpress / Novel stem cell platform improves study of endometriosis
Scientists led by Julie Kim, Ph.D., the Susy Y. Hung Research Professor of obstetrics and gynecology in the Division of Reproductive Science in Medicine, have developed a novel stem cell platform that provides a new way to ...
Phys.org / A cell-motility pathway helps set the pace of embryo development
A molecular pathway known for controlling cell shape and movement also helps regulate the rhythm by which the vertebrate body is divided into repeated segments, FMI researchers report in the journal Development.
Tech Xplore / Neural network approach makes AI uncertainty checks far more efficient
McGill University researchers have developed a more energy-efficient method of building AI systems that are better at measuring—and indicating—their own uncertainty. This will help users determine when human oversight is ...
Medical Xpress / Air pollution induces changes in the oral mucosa and may worsen periodontal disease
Air pollution can affect oral health. A study conducted in Brazil by researchers from São Paulo State University (UNESP) and the University of São Paulo (USP) demonstrated for the first time that exposure to fine particulate ...
Phys.org / Who helps more—low-income earners or the wealthy? It depends on the situation
Are people from lower socioeconomic backgrounds more willing to help—or do the wealthy give more? For years, research has provided conflicting answers. A new study by Kühne Logistics University (KLU), based on data from approximately ...
Tech Xplore / At 0.8 nanometers, carbon film may replace two layers in future chip wiring
As transistors inside microchips continue to shrink, the metal wiring that connects them is becoming a growing obstacle to faster, more energy-efficient chips. Narrower wires have greater electrical resistance, while smaller ...
Medical Xpress / AI-guided screening identifies nine drugs that may slow childhood dementia
An Australian research collaboration has identified several existing TGA-approved medicines that could help slow brain damage in children with a rare form of dementia—offering hope for faster treatment options.
Medical Xpress / 'Molecular glue' redirects a cancer-driving protein to activate cell death
A two-headed molecule designed by Stanford Medicine researchers hijacks one of the most common protein drivers of B-cell lymphoma, flipping it from its role as a promoter of cell growth into an arbiter of cell death. In mice, ...
Phys.org / How sex sheds evolutionary baggage
Why is there sex—or, more precisely, sexual reproduction? If you're an evolutionary biologist, the answer isn't obvious. Sexual reproduction is biologically costly, requiring not only competition for mates but also the creation ...
Phys.org / Nanoparticle combines two strategies to speed up the healing of chronic wounds
Researchers at the University of São Paulo (USP) in Ribeirão Preto, Brazil, have developed a nanoparticle that can address the various factors hindering the healing of chronic wounds, which include ulcers associated with ...
