Patients with COVID-19 who have an acute ischemic stroke (AIS) experience more severe strokes, have worse functional outcomes and are more likely to die of stroke than AIS patients who do not have COVID-19. The wide range of complications associated with COVID-19 likely explain the worse outcomes.
A baby girl in Texas -- born prematurely to a mother with COVID-19 -- is the strongest evidence to date that intrauterine (in the womb) transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can occur, according to a new report.
As we age, the immune system gradually becomes impaired. One aspect of this impairment is chronic inflammation in the elderly, which means that the immune system is constantly active and sends out inflammatory substances. Such chronic inflammation is associated with multiple age-related diseases including arthritis and Alzheimer's disease, and impaired immune responses to infection. One of the...
Lopinavir is a drug against HIV, hydroxychloroquine is used to treat malaria and rheumatism. Until recently, both drugs were regarded as potential agents in the fight against the coronavirus SARS-CoV-2. Researchers have now discovered that the concentration of the two drugs in the lungs of Covid-19 patients is not sufficient to fight the virus.
A commentary published in the journal Pediatrics concludes that children infrequently transmit COVID-19 to each other or to adults and that many schools, provided they follow appropriate social distancing guidelines and take into account rates of transmission in their community, can and should reopen in the fall.
A new study has shown that coral outplant survival is likely to drop below 50% if sea surface temperatures exceed 30.5 degrees Celsius and that survival rates can also be predicted by considering temperature conditions in the year prior to outplanting.
A gene has been discovered that can naturally suppress the signs of Alzheimer's Disease in human brain cells. The scientists have also developed a new rapid drug-screening system for treatments that could potentially delay or prevent the disease.

Researchers have added fresh evidence that early exposure to vaccine-, bacterial- or microbiota-derived antigens has a dramatic effect on the diversity of antibodies an adult mammal will have to fight future infections by pathogens. This antibody diversity is called the clonal repertoire -- basically different single cells with distinct antibody potential that can multiply into a large clone of...
Study finds that teenagers utilize Long-Acting Reversible Contraception (LARC) at a rate five times higher than the United States as a whole.
Researchers used single-nucleus RNA sequencing to compare transcriptional responses to acute cocaine in 16 unique cell populations from the brain nucleus accumbens. The atlas is part of a major study that used multiple cutting-edge technologies to describe a dopamine-induced gene expression signature that regulates the brain's response to cocaine. The study shows neurobiological processes that...
