Results of a new multicenter study published in the New England Journal of Medicine found that vaccination with a primary series of the Pfizer-BioNTech mRNA COVID-19 vaccine reduced the risk of COVID-19-associated hospitalizations in children ages 5-11 years by two-thirds during the Omicron period.

Cancer cells can disrupt a metabolic pathway that breaks down fats and proteins to boost the levels of a byproduct called methylmalonic acid, thereby driving metastasis, according to research led by scientists at Weill Cornell Medicine. The findings open a new lead for understanding how tumors metastasize, or spread to other tissues, and hints at novel ways to block the spread of cancer by targeting the process.

The antibodies generated by Pfizer's COVID-19 vaccine rise more slowly and decline more quickly than those generated by the Moderna vaccine, according to a new study from UVA Health. The study also finds that older recipients of the Pfizer vaccine generated fewer antibodies than did younger recipients - but this wasn't the case for Moderna, where age did not appear to be a factor.

A new protein-based antiviral nasal spray developed by researchers at Northwestern University, University of Washington and Washington University at St. Louis is being advanced toward Phase I human clinical trials to treat COVID-19.

Designed computationally and refined in the laboratory, the new protein therapies thwarted infection by interfering with the virus' ability to enter cells.

Since the first reports of HIV infection in the early 1980s, multiple clinical trials have tested potential vaccines against the virus, but unfortunately, HIV has numerous defense mechanisms that prevent a person's immune system from mounting an effective response following HIV vaccination. An alternative anti-HIV strategy called Vectored ImmunoProphylaxis (VIP) designed by researchers at the

The average person will take more than 600 million breaths over the course of their life. Every breath stretches the lungs’ tissues with each inhale and relaxes them with each exhale. The mere motions of breathing are known to influence vital functions of the lungs, including their development in babies, the production of air-exchange-enhancing fluid on their inner surfaces, and maintenance of healthy tissue structure.

Licorice is more than a candy people either love or hate - it may play a role in preventing or treating certain types of cancer, according to researchers at the University of Illinois Chicago.

Gnanasekar Munirathinam and his research team are studying substances derived from the licorice plant Glycyrrhiza glabra to determine if they could be used to prevent or stop the growth of prostate cancer.
