A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older。 Participants spent just a few minutes a day on brain-training activities, and researchers found measurable gains across multiple aspects of brain health
As newborn neurons make their way through the developing brain, they must squeeze through incredibly tight spaces to reach their final destinations。 Researchers discovered that this physical journey routinely causes some of the most severe forms of DNA damage—double-strand breaks—yet the young brain has evolved an impressive ability to repair the d
Scientists at the University of Hong Kong have created a remarkable new type of brain-inspired chip that can function just above absolute zero, one of the coldest environments imaginable。 By using a standard silicon carbide transistor in a completely new way, the team made a single device behave like an energy-efficient neuron, firing electrical “s
A newly identified molecule called OLE helped restore the brain’s immune cells to a more protective state in Alzheimer’s models。 The treatment reduced toxic plaque buildup and improved memory, raising hopes for a new therapeutic approach
Humans evolved to pay close attention to danger, but today that instinct is being overwhelmed by an endless supply of bad news from around the world。 Researchers say the answer isn’t to stop following current events—it’s to build healthier habits around how, when, and where we get our news
Researchers gave top AI models a classic attention test used in psychology and found a major flaw。 While the models could correctly name colors in short lists, their performance deteriorated sharply as the task became longer and more complex。 Some leading systems fell from over 90% accuracy to nearly complete failure
Learning a musical instrument later in life may help keep the brain younger for longer。 In a four-year study, older adults who continued practicing maintained their memory performance and showed less age-related brain shrinkage than those who quit。 The benefits were especially noticeable in brain regions tied to memory and learning
New studies suggest consciousness can't be judged solely by behavior, whether it's a chatbot discussing philosophy or a bee searching for nectar。 Researchers are increasingly focusing on the internal mechanisms of brains and computers, concluding that today's AI is likely not conscious while leaving open the possibility for both conscious insects a
A groundbreaking new connectome maps every neural connection in an adult fruit fly’s central nervous system, creating an unprecedented view of how the brain and body work together。 The findings suggest that complex behaviors emerge from distributed local circuits rather than a single central controller, offering new clues about intelligence, moveme
A tiny set of ancient genetic “switches” may have played a surprisingly large role in making human language possible。 Researchers found that these DNA regions, which act like volume controls for genes involved in brain development, have an outsized influence on language ability despite making up less than 0。1% of the genome
