To fight infections and heal injuries, immune cells need to enter tissue. They also need to invade tumors to fight them from within. Scientists have now discovered how immune cells protect their sensitive insides as they squeeze between tissue cells. The team lays the foundation for identifying new targets in cancer treatment.

Researchers analyzed thousands of microglia from different brain regions of deceased patients who had been diagnosed with a variety of neuropsychiatric and neurodegenerative disorders. Their results support the idea that microglia may play critical roles in some cases of brain disease while also providing a potentially valuable guide for future studies.

Large wildfires and severe heat events are happening more often at the same time, worsening air pollution across the western United States, a study has found. In 2020, more than 68% of the western U.S. -- representing about 43 million people -- were affected in one day by the resulting harmful-levels of air pollution, the highest number in 20 years. The study found that these concurrent air pollution events are increasing not only in frequency but duration and geographic extent across the region. They have become so bad that they have reversed many gains of the Clean Air Act. The conditions that create these episodes are also expected to continue to increase, along with their threats to human health.

The bacterium Vibrio cholerae is the causative agent of the diarrheal disease cholera and is responsible for seven known pandemics. The seventh cholera pandemic began in 1961 and is still active. Unlike previous pandemics, it is caused by cholera strains of a slightly different type. How did the modified cholera strains develop and spread, and what might have contributed to their success? Scientists have now gained new insights into a molecular mechanism that provides insight into the interactions between cholera bacteria and may have played a role in the emergence of the seventh pandemic.

The school closures in spring 2020 had a negative effect on the health and well-being of many young people. But homeschooling also had a positive flipside: Thanks to sleeping longer in the morning, many teenagers reported improved health and health-related quality of life. The study authors therefore believe school days should begin later in the morning.
