Summary: Research is shifting attention from weight loss to addiction treatment: a new animal study finds that tirzepatide—the active ingredient in Mounjaro—substantially reduces alcohol intake and suppresses relapse-like drinking behavior. In rodent models, voluntary alcohol consumption fell by more than half and binge-like drinking episodes were markedly reduced. The investigators report that tirzepatide dampens the … Read more

Summary: New research suggests ethnicity may influence sensitivity to bitter tastes, possibly linked to anatomical differences on the tongue. Source: University of Copenhagen Two studies from the University of Copenhagen report that Danish and Chinese participants differ in sensitivity to bitter tastes, a difference the researchers associate with variations in the distribution of small bumps … Read more

Summary: Reduction in tongue fat volume appears to be the key connection between weight loss and improvement in obstructive sleep apnea. Source: University of Pennsylvania School of Medicine Weight loss is a well-recognized way to improve symptoms of obstructive sleep apnea (OSA), but the exact mechanism has been uncertain. Researchers at the Perelman School of … Read more

Summary: A new study from EPFL demonstrates how a soft, compliant robotic hand—built from silicone skin, springs, and flexible joints—can self-organize reliable grasps without detailed environmental sensing or elaborate control software. The ADAPT hand (Adaptive Dexterous Anthropomorphic Programmable sTiffness) successfully picked up 24 different objects with a 93% success rate using only four programmed motions. … Read more

Summary: Researchers examine the sociocultural mental health phenomenon known as hikikomori, in which people withdraw from society and remain isolated for extended periods. Source: The Conversation Brief periods of withdrawal from daily life are common and can be healthy. Short breaks from social demands can reduce acute stress, aid recovery from illness and exhaustion, and … Read more

Summary: A new machine-learning study decodes behavioral strategies in worms, offering insights that may help explain how animals, including humans, make decisions. Source: Kyoto University. Researchers present a machine-learning method to infer animal preferences from behavior; the findings offer new perspectives on decision-making processes Interpreting what animals want is a familiar challenge for pet owners … Read more

Summary: Researchers have identified a cellular “trash disposal” mechanism that directly influences the pace of aging. While circular RNA has long been observed to build up in cells with age, this study provides direct evidence that that accumulation is not merely a marker but a causal factor in aging. The team discovered an enzyme, RNASEK, … Read more

Summary: New research indicates that repeated blows to the head sustained while playing youth football can affect brain development. The study found measurable changes to nerve fiber bundles in the corpus callosum. Source: RSNA MRI reveals structural brain changes in youth football players after repeated head impacts Magnetic resonance imaging (MRI) scans show that repetitive … Read more

Summary: A large new nationwide study finds no evidence that the measles, mumps, and rubella (MMR) vaccine increases the risk of autism. The researchers observed no higher autism rates following MMR vaccination, including among children considered at higher risk for autism. In a subgroup analysis, vaccinated girls showed a 16%–21% lower risk of autism. The … Read more

Summary: Greater activity in the anterior prefrontal cortex before trauma exposure was associated with stronger resilience to post-traumatic stress symptoms. Source: Radboud University Why does one person develop post-traumatic symptoms after a stressful event while another does not? New longitudinal research with police recruits suggests that higher activity in the anterior prefrontal cortex — a … Read more
