Summary: For the first time, scientists have shown how heavy alcohol use leads to long-term cognitive impairments by damaging brain circuits responsible for decision-making. In a rat model, animals exposed to high alcohol levels performed significantly worse on a complex, shifting-reward task, even after nearly three months of sobriety.These decision-making...
Summary: A large study of over 72,000 pregnant women found that those infected with SARS-CoV-2 during pregnancy were less likely to develop Long COVID than non-pregnant peers. Using data from two national databases, researchers found consistent results: about 16% of pregnant women developed Long COVID symptoms versus 19% of matched...
Summary: Researchers have developed a brain-computer interface that can synthesize natural-sounding speech from brain activity in near real time, restoring a voice to people with severe paralysis. The system decodes signals from the motor cortex and uses AI to transform them into audible speech with minimal delay—less than one second.Unlike...
Summary: A new study shows that weight training not only boosts physical strength but also protects the brains of older adults with mild cognitive impairment. After six months of twice-weekly resistance training, participants showed memory improvements and protection against brain atrophy in regions linked to Alzheimer’s disease.MRI scans revealed preserved...
Summary: A new study of over 45,000 young adults found that using screens in bed increases the risk of insomnia by 59% and cuts sleep by 24 minutes. Surprisingly, the type of activity—whether social media, movies, or studying—didn’t make a difference; it was the screen time itself that mattered most.Researchers...
