Tech Xplore / New memristor training method slashes AI energy use by six orders of magnitude
In a Nature Communications study, researchers from China have developed an error-aware probabilistic update (EaPU) method that aligns memristor hardware's noisy updates with neural network training, slashing energy use by ...
Phys.org / Scientists design artificial pain receptor that senses pain intensity and self-heals
All over the body are tiny sensors called nociceptors whose job is to spot potentially harmful stimuli and send warning signals to the brain and spinal cord, helping protect us from injury or tissue damage.
Phys.org / Construction emissions are higher than thought—but the solution isn't building less, new study finds
Many cities are making great strides in the fight against climate change, such as improving building energy efficiency, reducing traffic congestion and switching to renewable power sources. But there is another often overlooked ...
Medical Xpress / Taking acetaminophen during pregnancy does not increase risk of autism, ADHD or intellectual disabilities
Taking acetaminophen during pregnancy does not increase the risk of autism, attention-deficit hyperactivity disorder (ADHD), or intellectual disability among children. That is according to the most rigorous analysis of the ...
Phys.org / Understanding the unusual chirality-driven anomalous Hall effect via scattering theory
A new framework for understanding the nonmonotonic temperature dependence and sign reversal of the chirality-related anomalous Hall effect in highly conductive metals has been developed by scientists at Science Tokyo. This ...
Phys.org / Collapse of the Tang dynasty: Climate change likely played a role
Environmental phenomena and their consequences can disrupt social structures and destabilize political systems. An interdisciplinary research team demonstrated this using the example of the late Tang dynasty in medieval China.
Phys.org / Chile declares emergency as wildfires kill at least 19
Uncontrolled wildfires tore through communities in southern Chile, leaving charred ruins in their wake and at least 19 dead, authorities said, announcing the latest toll on Sunday.
Phys.org / Earth system models overestimate river flow increases, research reveals
Understanding how water moves through the Earth system is fundamental to predicting climate impacts and ensuring sustainable water management. Yet despite decades of research, uncertainties persist regarding how global precipitation ...
Phys.org / Large parts of the tropics overlooked in environmental research, study says
Environmental research in the tropics is heavily skewed, according to a comprehensive study led by Umeå University. Humid lowland forest ecosystems receive a disproportionate amount of attention, while colder and drier regions ...
Medical Xpress / A new robotic system could perform delicate eye surgery
Retinal vein occlusion (RVO) is a severe disease that occurs when a vein in the light-sensitive layer at the back of the eye (i.e., the retina) becomes blocked, which results in a loss of vision. There are currently a few ...
Phys.org / Exposing how humidity can escalate a heat wave
When Floridians talk about extreme weather, hurricanes dominate the conversation. Each season brings updates on storm tracks, cone predictions and wind speeds, all in the hopes of predicting the unpredictable. But a quieter, ...
Phys.org / Two harmful gene variants can restore function when combined, study reveals
Sometimes, in genetics, two wrongs do make a right. A research team has recently shown that two harmful genetic variants, when occurring together in a gene, can restore function—proving a decades-old hypothesis originally ...
