Genetic Study Reveals Biological Drivers of Frailty in Aging

Researchers at McMaster University have identified, for the first time, a novel region of DNA and two associated genes connected to frailty, offering neurological and immune-related insights that might help explain why some older adults are more likely to be frail than others.

Is Fast Food Harming the Gut Health of Seagulls? We Could be About to Find Out

A brand new study looking at the impact of fast food on the gut health of seagulls has just won funding from the Royal Society.

"Zombie" Macrophages Accumulate in Aging Tissues and Diseased Livers

UCLA researchers have identified a rogue population of immune cells that quietly accumulates in aging tissues and in the livers of people with fatty liver disease. Clearing these cells, they found, dramatically reduced inflammation and reversed liver damage in mice - even while the animals remained on an unhealthy diet.

Largest Genetic Study Reveals New Biological Clues for Severe Pregnancy Sickness

The USC research team that recently identified the hormone-encoding gene GDF15 as a key driver of pregnancy sickness has identified 9 additional genes linked to its most severe form, hyperemesis gravidarum (HG).

Early Epigenetic Changes and Gut Microbiome Interact to Shape Neurodevelopment

The gut microbiome and epigenetics-molecular switches that turn genes on or off-are intertwined, and both contribute to neurodevelopment, finds a study publishing April 10 in the Cell Press journal Cell Press Blue.

Novel ENDOtollins Block Harmful Inflammation While Preserving Infection Response

Scripps Research scientists have developed a new class of drug compounds that reduce harmful inflammation while leaving the body's ability to fight infections intact-a long-sought goal in treating autoimmune diseases.

Cysteine Pathways Shape T Cell Expansion and Cancer Defense

A research team from the Johns Hopkins Kimmel Cancer Center, its Bloomberg~Kimmel Institute for Cancer Immunotherapy and the Johns Hopkins Bloomberg School of Public Health have discovered how the immune system's CD8+ T cells use the nutrient cysteine to control two essential functions that compete for this resource - the immune cell's ability to multiply and its ability to kill cancer cells.

Genetic Study Reveals Insecticide Resistance in Malaria Vector Mosquitoes

Anopheles darlingi mosquitoes-a major vector of malaria in South America-are evolving in response to insecticides, which may make them harder to kill and malaria more difficult to control, according to a new study led by Harvard T.H. Chan School of Public Health.
