Gut hormone increases response to food

McGill University

The holiday season is a hard one for anyone watching their weight. The sights and smells of food are hard to resist. One factor in this hunger response is a hormone found in the stomach that makes us more vulnerable to tasty food smells, encouraging overeating and obesity.

An ancient strain of plague may have led to the decline of Neolithic Europeans

Cell Press

A team of researchers from France, Sweden, and Denmark have identified a new strain of Yersinia pestis, the bacteria that causes plague, in DNA extracted from 5,000-year-old human remains. Their analyses, publishing December 6 in the journal Cell, suggest that this strain is the closest ever identified to the genetic origin of plague.

Natural selection in the womb can explain health problems in adulthood

Columbia University, Mailman School of Public Health

Conditions encountered in the womb - when the embryo consists of only about 100 cells - can have life-long impact on health. Scientists previously assumed that this is because embryos respond to adverse conditions by programming their gene expression. Now an international team of researchers at the Leiden University Medical Center, Wageningen University and Research, Lund University, Columbia University Mailman School of Public Health in New York propose a radically different alternative. Rather than being programmed by the environment, random differences in gene expression may provide some embryos with a survival advantage, in particular when conditions are harsh. By studying DNA methylation, an important mechanism to control gene activity, the researchers found that a specific part of the DNA methylation pattern was missing among famine-exposed individuals. The findings are published in the journal Cell Reports.

Researchers Discover Why Some Parts of the Body Have Hair and Others Don’t

Perelman School of Medicine at the University of Pennsylvania

Why do humans have hair on our arms and legs but not on the palms of our hands and the soles of our feet? It’s a fundamental question in human evolution that researchers at the Perelman School of Medicine at the University of Pennsylvania say they’ve found clues to in a new study.

Brain, muscle cells found lurking in kidney organoids grown in lab

Washington University in St. Louis

New research has identified rogue cells – namely brain and muscle cells – lurking within kidney organoids. The presence of such cells indicates that the “recipes” used to coax stem cells into becoming kidney cells inadvertently are churning out other cell types.
