In a study of more than 400 adults with normal blood pressure, those who had high levels of stress hormones detected in their urine were more likely to develop high blood pressure over the next 6-7 years. Higher levels of the stress hormone cortisol were also linked to an increased risk of cardiovascular events, including heart attack and stroke.

The human brain regions responsible for working memory content are also used to gauge the quality, or uncertainty, of memories, a team of scientists has found. Its study uncovers how these neural responses allow us to act and make decisions based on how sure we are about our memories.

People often unconsciously synchronize bodily functions like heartbeat and breathing when they share an experience, such as a live performance or have a personal conversation. According to a new study, subjects' heart rates synchronize even if they are just listening to a story by themselves, and this synchronization only occurs when the subjects are paying attention to the story.

New research has examined the association between vitamin D and COVID-19, and found that ambient ultraviolet B (UVB) radiation (which is key for vitamin D production in the skin) at an individual's place of residence in the weeks before COVID-19 infection, was strongly protective against severe disease and death.

Scientists have developed a technique for reconstructing whole genomes, including the human genome, on a personal computer. This technique is about a hundred times faster than current state-of-the-art approaches and uses one-fifth the resources. The study allows for a more compact representation of genome data inspired by the way in which words, rather than letters, offer condensed building blocks for language models.

By using artificial intelligence to mine big data related to artists, film directors and scientists, researchers have found that years of exploration (studying diverse styles or topics) immediately followed by years of exploitation (focusing on a narrow area to develop deep expertise) can lead to a career's greatest hits.

A new study has shown that the protein RNF5 plays an unusual role in acute myeloid leukemia (AML). Unlike its expected role, marking aberrant proteins for destruction, RNF5 binds with a second cell protein called RBBP4 to control expression of genes implicated in AML. These findings have important implications for improving AML patient outcomes.
