Want to boost your brain as you age? Music might be the answer

Just as melodies transcend time, playing music holds back age-related neural upregulation, supporting better speech perception in older musicians.

Long-term musical training may mitigate the age-related decline in speech perception by enhancing cognitive reserve, according to a study published in PLOS Biology by Claude Alain from the Baycrest Academy for Research and Education, Canada, and Yi Du from the Chinese Academy of Sciences.

Normal aging is typically associated with declines in sensory and cognitive functions...

Early-life to endocrine-disrupting chemicals may fuel food preferences

Exposure to endocrine-disrupting chemicals in early life, including during gestation and infancy, results in a higher preference for sugary and fatty foods later in life, according to an animal study being presented Sunday at ENDO 2025, the Endocrine Society’s annual meeting in San Francisco, Calif.

Endocrine-disrupting chemicals are substances in the environment (air, soil or water supply), food sources, personal care products and manufactured products that interfere with the normal function of the body’s endocrine system...

Research led by Naval Medical University’s Changzheng Hospital in China reports that an off-the-shelf cell therapy built from induced pluripotent stem cells (iPSCs) loosened life-limiting skin and organ scarring in a woman with systemic sclerosis.

Systemic sclerosis progressively suffocates tissue through immune misfires, collapsed micro-vessels, and runaway collagen conditions that resist standard immunosuppressants, biologics, and anti-fibrotic drugs while driving a 40% 10-year mortality.

Cell-based approaches such as hematopoietic-stem-cell transplants and CAR-T therapies have shown promise but carry high toxicity or labor-intensive custom manufacturing, leaving clinicians and patients in search of safe...

A robot trained on videos of surgeries performed a lengthy phase of a gallbladder removal without human help. The robot operated for the first time on a lifelike patient, and during the operation, responded to and learned from voice commands from the team—like a novice surgeon working with a mentor.

The robot performed unflappably across trials and with the expertise of a skilled human surgeon, even during unexpected scenarios typical in real-life medical emergencies.

The work, led by Johns Hopkins University researchers, is a transformative advancement in surgical robotics, where robots can perform with both mechanical precision and human-li...
