Moderate-to-regular daily sleep patterns are associated with enhanced cognitive function

A new study published in Sleep Medicine found that daily sleep patterns have a significant impact on cognitive function. Researchers discovered that individuals with moderate-to-regular sleep patterns performed better in cognitive assessments than those with highly irregular or rigid sleep patterns.

New model aims to demystify ‘steam worlds’ beyond our solar system

Astrobiologists have developed a new model to characterize water-rich sub-Neptunes, which are planets with sizes and masses between those of Earth and Neptune. This model accounts for the complex behavior of supercritical water and its implications for planetary formation and potential habitability.

Researchers detail reliable measurement for blood-brain barrier opening using focused ultrasound

Researchers from the University of Maryland School of Medicine have developed a reliable measurement for opening the blood-brain barrier using focused ultrasound. By analyzing acoustic emissions signals generated by circulating microbubbles, they found that this method can predict blood-brain barrier opening in patients with glioblasto...

Most epilepsy patients wait a year after starting treatment for seizure relief

A new study reveals that most epilepsy patients with focal epilepsy will still experience seizures for at least a year after starting treatment. The study suggests that neurologists should rethink their initial approach to antiseizure therapy, as many patients may not respond well to the first medication or regimen prescribed.
