A new study finds that the duration and timing of school lunch and recess affect food choices and physical activity in children. Research suggests that scheduling recess before lunch reduces food waste, but may lead to consuming more vegetables when lunch is offered first, and increased physical activity during longer combined periods.
A new study found that increased biodiversity is not associated with reduced levels of infectious disease, and in some cases, disease burdens actually increased as areas became more forested. However, increasing urbanization was shown to reduce disease due to improved access to medical care and vaccinations.
A study by Hokkaido University researchers found that voltage rhythms are synchronized across the entire suprachiasmatic nucleus (SCN), maintaining a tissue-wide rhythm. This discovery suggests that inter-cellular interactions within the SCN may be responsible for synchronizing voltage changes, separate from asynchronous calcium rhythms.
Researchers have discovered that altered immune cells activated by placental ischemia can exacerbate preeclampsia symptoms. However, deleting these cells in animal models of the condition reduces hypertension, inflammation, and fetal growth restriction.
Researchers analyze amino acid stability under various extraterrestrial conditions, including temperature, pH, and radiation, to identify potential building blocks of alien life. The study aims to find structural characteristics that lead to higher stability in these conditions.
Researchers at Kobe University developed a new solar cell structure that can absorb spectral components of longer wavelengths, increasing energy conversion efficiency to over 50%. The design achieved up-conversion based on two photons, reducing energy loss by over 100 times compared to previous methods.
A new study by Dara Orbach, PhD, uses computed tomography scans and silicone models to visualize the anatomy of dolphin copulation. The research reveals complex vaginal folds and spirals that interact with the penis during fertilization.
The star-nosed mole possesses an extremely efficient nervous system that enables it to identify and eat food in under 2 seconds. Its distinctive star organ contains over 100,000 nerve fibers, making it the most sensitive known touch organ in any mammal.
Researchers have developed a quick and accurate diagnostic test for bacteria resistant to colistin, a last-resort antibiotic. The test can distinguish between bacteria with plasmid-encoded resistance, which is considered more dangerous, and those that are not.
Researchers discovered carvedilol's protective effect against UVB-induced cell damage that leads to skin cancer. The study suggests carvedilol could be incorporated into a skin cream or spray to prevent skin cancer.
