A novel AI-powered study explores evolutionary differences between male and female birdwing butterflies, shedding new light on a historic debate between Charles Darwin and Alfred Russel Wallace. Using machine learning to analyze over 16,000 butterfly specimens, researchers found that both sexes contribute to species diversity.
A new neuroprosthetic interface allows prosthetic limbs to be controlled by the body’s nervous system, resulting in a natural walking gait. The surgery reconnects muscles, providing proprioceptive feedback, enabling users to walk faster and navigate obstacles more effectively.
New research shows that we can distinguish between accurate memories and those filled with general knowledge. A study revealed that when memories are based on ‘prototypical’ information, our confidence in them decreases. This awareness helps us accurately assess the reliability of our recollections. These findings have significant implications for the credibility of eyewitness accounts in […]
A new study reveals sex differences in how the brain’s reward pathways function, specifically in the hippocampus and nucleus accumbens. Males and females use different molecular mechanisms to strengthen these connections, influencing responses to treatments for disorders like depression and substance abuse. The findings highlight the need for more gender-specific research to develop effective therapies. […]
A landmark Supreme Court decision that reins in federal agencies’ authority is expected to hold dramatic consequences for the nation’s health care system, calling into question government rules on anything from consumer protections for patients to drug safety to nursing home care. The June 28 decision overturns a 1984 precedent that said courts should give […]
