A research team performs machine learning-powered photoacoustic/ultrasound imaging for thyroid cancer classification.

Babies younger than four weeks old, called neonates, were once thought not to perceive pain due to not-yet-fully-developed sensory systems, but modern research says otherwise.

Listening to vocal music is a simple and cost-efficient way of promoting recovery and brain health after a stroke.

A new study provides a potential tool for unraveling the mystery of how experiences can cause inheritable changes to an animal's biology. By mating nematode worms, they produced permanent epigenetic changes that lasted for more than 300 generations.

Recess quality, not just the amount of time spent away from the classroom, plays a major role in whether children experience the full physical, mental and social-emotional benefits of recess, a new study has found.

Scientists investigated the efficiency of splicing across different human cell types. The results were surprising in that the splicing process appears to be quite inefficient, leaving most intronic sequences untouched as the transcripts are being synthesized. The study also reports variable patterns between the different introns within a gene and across cell lines, and it further highlights the complexity of how newly transcripts are processed into mature mRNAs.

Researchers have found a vital mechanism, previously thought to have disappeared as mammals evolved, that helps protect mammalian stem cells from RNA viruses such as SARS-CoV-2 and Zika virus. The scientists suggest this could one day be exploited in the development of new antiviral treatments.

Tooth loss is a risk factor for cognitive impairment and dementia -- and with each tooth lost, the risk of cognitive decline grows, according to a new analysis.

Investigators conducted a systematic review and meta-analysis of 38 randomized controlled trials of omega-3 fatty acids. Overall, they found that omega-3 fatty acids improved cardiovascular outcomes. Results showed a significantly greater reduction in cardiovascular risk in studies of EPA alone rather than EPA+DHA supplements.

The world's largest study of global climate related mortality found deaths related to hot temperatures increased in all regions from 2000 to 2019, indicating that global warming due to climate change will make this mortality figure worse in the future. The international research team looked at mortality and temperature data across the world from 2000 to 2019, a period when global temperatures rose by 0.26C per decade.

A metabolic control pathway that regulates T follicular helper cells offers targets for drugs to stimulate the adaptive immune response.

Adults with ADHD are at higher risk of a wide range of physical conditions, including nervous system, respiratory, musculoskeletal, and metabolic diseases, according to a large register-based study in Sweden.

Using artificial intelligence, scientists have identified thousands of genetic mutations likely to affect the immune system in mice.
