A 3-D printer that rapidly produces large batches of custom biological tissues could help make drug development faster and less costly. Nanoengineers at the University of California San Diego developed the high-throughput bioprinting technology, which 3-D prints with record speed—it can produce a 96-well array of living human tissue samples within 30 minutes. Having the …
A new global study of 30-day outcomes in children and adolescents with COVID-19 found that while death was uncommon, the illness produced more symptoms and complications than seasonal influenza.
A modeling study found that with controlled community transmission and moderate mitigation strategies in place, schools can reopen safely. Asymptomatic screening is one mitigation strategy identified that could facilitate reopening at higher local incidence while minimizing transmission risk. The findings are published in Annals of Internal Medicine.
People whose sleep pattern goes against their natural body clock are more likely to have depression and lower levels of wellbeing, according to a largescale new study.
Citizen opposition to COVID-19 vaccination has emerged across the globe, prompting pushes for mandatory vaccination policies. But a new study based on evidence from Germany and on a model of the dynamic nature of people’s resistance to COVID-19 vaccination sounds an alarm: Mandating vaccination could have a substantial negative impact on voluntary compliance.
Heart attacks and strokes—the leading causes of death in human beings—are fundamentally blood clots of the heart and brain. Better understanding how the blood-clotting process works and how to accelerate or slow down clotting, depending on the medical need, could save lives.
To investigate factors that can jeopardize pregnancy success in cattle, researchers at the University of São Paulo (USP) in Brazil used a kind of chip to mimic the environment of the endometrium, the tissue that lines the inside of the uterus.
The portion of food that you put on your plate and how fast you eat it could determine how much you’re eating—or potentially overeating.
An experimental, lab-made antibody can completely prevent nonhuman primates from being infected with the monkey form of HIV, new research published in Nature Communications shows.
Normally, the ACE2 enzyme helps regulate our blood pressure. The enzyme sits on the surface of cells, including cells in the lungs, but in connection with COVID-19 it has been found that ACE2 also functions as a gateway for the virus.
