Salmonella biofilm protein causes autoimmune responses -- Possible link with Alzheimer's

Scientists have demonstrated that a Salmonella biofilm protein can cause autoimmune responses and arthritis in animals.

Study identifies unique cells that may drive lung fibrosis

This is one of the first comprehensive looks at lung cells using a technology called single-cell RNA sequencing. Instead of examining a mash-up of many cells from a tissue sample, single-cell sequencing allowed researchers in this study to closely examine the individual cells that make up the lungs; to identify their function, and ultimately understand...

Critical early step of the visual process uncovered

The key components of electrical connections between light receptors in the eye and the impact of these connections on the early steps of visual signal processing have been identified for the first time, according to new research.

Community initiative increases teenage use of effective contraception

Study finds that teenagers utilize Long-Acting Reversible Contraception (LARC) at a rate five times higher than the United States as a whole.

A complex gene program initiates brain changes in response to cocaine

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...

New study supports remdesivir as COVID-19 treatment

A new study found that remdesivir potently inhibited SARS-CoV-2, the virus which causes COVID-19, in human lung cell cultures and that it improved lung function in mice infected with the virus.

CT of coronavirus disease (COVID-19) versus CT of influenza virus pneumonia

A new article investigating the differences in CT findings between coronavirus disease (COVID-19) pneumonia and influenza virus pneumonia found that most lesions from COVID-19 were located in the peripheral zone and close to the pleura, whereas influenza virus was more prone to show mucoid impaction and pleural effusion. The more important role of CT...

Biologists trace plants' steady mitochondrial genomes to a gene found in viruses, bacteria

Biologists have traced the stability of plant mitochondrial genomes to a particular gene - MSH1 - that plants have but animals don't. Their experiments could lend insight into why animal mitochondrial genomes tend to mutate.

No association found between exposure to mobile devices and brain volume alterations in adolescents

A new study of 2,500 Dutch children is the first to explore the relationship between brain volume and different doses of radiofrequency electromagnetic fields.

Women who deliver by C-section are less likely to conceive subsequent children

Women who deliver their first child by cesarean section (C-section) are less likely to conceive a second child than those who deliver vaginally, despite being just as likely to plan a subsequent pregnancy, according to researchers. The team followed more than 2,000 women for three years after they delivered their first child.
