A dial for tuning the immune system: Discovery sheds light on why COVID makes some sicker than others
Researchers have discovered a protein variant that serves as a knob for regulating the body's innate immune response. The findings could lead to new therapies for Long COVID, autoimmune disorders, and more.

You are what you eat...and so are your grandkids? Study links poor diet to multi-generational health issues
Is it possible to pass on the effects of malnutrition? A new animal study found that a protein-deficient diet in one generation created related health risks -- lower birth-weight, smaller kidneys -- in offspring that lasted four generations.

Scientists transform ubiquitous skin bacterium into a topical vaccine
Scientists' findings in mice could translate into a radical, needle-free vaccination approach that would also eliminate reactions including fever, swelling and pain.

Toxoplasma gondii parasite uses unconventional method to make proteins for evasion of drug treatment
A study sheds new light on how Toxoplasma gondii parasites make the proteins they need to enter a dormant stage that allows them to escape drug treatment.

Researchers discover a genetic disposition increasing the risk of breast cancer metastasis
Metastasis is responsible for 90 percent of cancer deaths. Researchers have found that the mutations driving it may stem from a commonly inherited variant of the PCSK9 gene.

Single mutation in H5N1 influenza surface protein could enable easier human infection
A single modification in the protein found on the surface of the highly pathogenic avian influenza (HPAI) H5N1 influenza virus currently circulating in U.S. dairy cows could allow for easier transmission among humans, according to new research. The study results reinforce the need for continued, vigilant surveillance and monitoring of HPAI H5N1 for potential genetic changes that could make the virus more transmissible in humans.
