SAN FRANCISCO, CA--May 26, 2021--In January 2021, reports of a new coronavirus variant that had emerged in California raised many concerns. Preliminary data suggested that it is more transmissible than the unmutated strains of SARS-CoV-2 (the virus that causes COVID-19) from which it evolved.

Now, a multifaceted collaboration between researchers at UC San Francisco, Gladstone Institutes, and other organizations across California provides a comprehensive portrait of the variant--including its interaction with the immune system and its potential to spread.

CHAMPAIGN, Ill. -- When the worsening COVID-19 pandemic prompted colleges to shutter their campuses and shift to remote learning in spring 2020, concerns arose that many underrepresented students in science, technology, engineering and mathematics disciplines would be demotivated and drop out in even greater numbers.

An in vitro study conducted by a group of researchers at São Paulo State University (UNESP) in Araraquara, Brazil, shows how fungi and bacteria can activate genes associated with head and neck tumors, as the metabolism of biofilms (communities in which these microorganisms self-organize in a structured and coordinated manner) stimulate tumor cells by favoring the cell signaling pathways required for tumor development and resistance to treatment. The findings include entirely novel information on the links between microbial biofilms and cell behavior in head and neck cancer.

BOSTON -- A multidisciplinary team from MassGeneral Hospital for Children (MGHfC), Brigham and Women's Hospital and other institutions have identified the mechanism of how an extremely rare but serious post-COVID-19 complication develops in children and adolescents. Led by MGHfC pediatric pulmonologist Lael Yonker, MD, researchers determined that viral particles remaining in the gut long after an initial COVID-19 infection can travel into the bloodstream, instigating the condition called Multisystem Inflammatory Syndrome in Children (MIS-C).

One in five women experience pain during intercourse. The latest edition of the Diagnostic and Statistical Manual of Mental Disorders, the bible of American psychiatrists, lists it under "genito-pelvic pain or penetration disorder." However, this type of pain is not purely psychological.

Provoked vestibulodynia is a condition experienced by approximately 8% of women in North America. It is characterized by severe pain at the vaginal opening during sexual intercourse or when inserting tampons. To reduce the burning sensation, many women apply lidocaine, an anesthetic cream.

CHAMPAIGN, Ill. -- Advanced microscope technology and cutting-edge geological science are giving new perspectives to an old medical mystery: How do kidney stones form, why are some people more susceptible to them and can they be prevented?

In a new paper published in the journal Nature Reviews Urology, researchers from the University of Illinois Urbana-Champaign, Mayo Clinic and other collaborators described the geological nature of kidney stones, outlined the arc of their formation, established a new classification scheme and suggested possible clinical interventions.

Annapolis, MD; May 26, 2021--A new study has mounted perhaps the most intricate, detailed look ever at the diversity in structure and form of bees, offering new insights in a long-standing debate over how complex social behaviors arose in certain branches of bees' evolutionary tree.
