Researchers have created a bioinspired gel that can regenerate tooth enamel by mimicking natural growth processes. The fluoride-free material forms a mineral-rich layer that restores enamel's strength and structure while preventing decay. It can even ...

Novo Nordisk's oral semaglutide 25 mg achieved up to 16.6% weight loss in a landmark study, rivaling injectable Wegovy. The pill also improved cardiovascular risk factors and physical activity levels. With a safety profile consistent with existing .. ...

Weill Cornell researchers uncovered how free radicals from astrocyte mitochondria can fuel dementia. Using new compounds that target these radicals at their source, they slowed brain inflammation and neuronal damage in mice. The findings reveal a ...

A Northwestern team transformed a common chemotherapy drug into a powerful, targeted cancer therapy using spherical nucleic acids. The redesign dramatically boosted drug absorption and cancer-killing power while avoiding side effects. This innovation ...

Virginia Tech researchers have shown that memory loss in aging may be reversible. Using CRISPR tools, they corrected molecular disruptions in the hippocampus and amygdala, restoring memory in older rats. Another experiment revived a silenced memory . ...

Meditation is widely praised for its mental health benefits, but new research shows that it can also produce unexpected side effects for some people--from anxiety and dissociation to functional impairment. Psychologist Nicholas Van Dam and his team . ...

Most U.S. adults don't realize alcohol raises cancer risk, and drinkers themselves are the least aware. Scientists say targeting these misbeliefs could significantly reduce alcohol-related cancer deaths.

Scientists have shown that brain connectivity patterns can predict mental functions across the entire brain. Each region has a unique "connectivity fingerprint" tied to its role in cognition, from language to memory. The strongest links were found in ...

Researchers discovered how rabies virus exerts massive control over host cells with very few genes. A key viral protein changes shape and binds RNA, allowing it to infiltrate different cellular systems. This adaptability could explain the power of .. ...

Cockroach infestations don't just bring creepy crawlers, they fill homes with allergens and bacterial toxins that can trigger asthma and allergies. NC State researchers found that larger infestations meant higher toxin levels, especially from female ...
