Jewish autistic pupils thrive as bilingual learners, after communities reject advice “not to teach Hebrew”

A University of Cambridge study found that Jewish autistic children who learn Hebrew as a second language benefit from their cultural identity and community involvement. Parents and teachers rejected outdated professional advice, instead teaching pupils Hebrew to enhance their spiritual and family life.

Infections from respiratory viruses follow a predictable seasonal pattern, researchers find

Researchers identified a clear-cut seasonal pattern in respiratory viruses, with peaks in January and lows in June, affecting hospital admissions. The study found that babies born in severe peak years were more likely to be infected and hospitalized, highlighting the importance of planning ahead for high seasons of illnesses.

A heart that beats (almost) like our own

Researchers at the University of Iowa found that the fruit fly's head-heart beats much like a human's, driven by an automatic muscle contraction and relaxation. This rhythmic pulsation generates hemolymph flow to the antennae and may help keep the brain clean.

Not all acne is equal: scientists reveal strains of C. acnes that promote skin health

A new study reveals that certain strains of Cutibacterium acnes (C. acnes) found on healthy skin can prolong the lifespan of Caenorhabditis elegans and help its innate immune system fight against Staphylococcus aureus. RNA sequencing analysis also shows these beneficial strains activate genes related to innate immunity.

Likely lower risks of adverse pregnancy outcomes from SARS-CoV-2 than previously feared

A national study in Sweden suggests that the risk of adverse pregnancy outcomes from SARS-CoV-2 is likely lower than previously feared. The study found that infants born to test-positive mothers had a higher risk of neonatal care and preterm birth, but no significant difference in stillbirths or low Apgar scores.

Pyruvate as an essential substance for the survival of neurons and Schwann cells under high-glucose milieu

Researchers found that pyruvate supplementation prevents rapid cell death of peripheral sensory neurons and Schwann cells under high-glucose conditions. Exogenous pyruvate may play a key role in maintaining glycolysis-TCA cycle flux by suppressing PARP activity, thereby supporting cellular viability and energy production.

Vascular disease in COVID-19 is not caused by viral infection of blood vessels
