Hints to aging lurk in fruit flies’ germline stem cells

Little hints of immortality are lurking in the stem cells of fruit flies. Stem cells that produce sperm use a genetic trick to stay perpetually young across generations, researchers at the University of Michigan Life Sciences Institute have discovered. Certain sections of the fruit fly genome get shorter with age. But remarkably, some reproductive cells can repair the shrinkage, the researchers report in the journal eLife.

Next-generation ‘active genetics’ tool opens new horizons

In 2015, University of California San Diego biologists Ethan Bier and Valentino Gantz developed a breakthrough technology known as "active genetics," which results in parents transmitting a genetic trait to most of their offspring (instead of 50 percent receiving the trait under standard inheritance).

Study reveals how devastating mitochondrial diseases strike families without any previous history

Researchers have shown for the first time how children can inherit a severe - potentially fatal - mitochondrial disease from a healthy mother.

Newly described super-silenced DNA reveals novel approach to reprogram cells

Newly described stretches of super-silenced DNA reveal a fresh approach to reprogram cell identity to use in regenerative medicine studies and one day in the clinic, according to a study in Molecular Cell last week by investigators from the Perelman School of Medicine at the University of Pennsylvania.

Researchers discover how high glucose levels in pregnancy affect baby's heart

Researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have discovered how high glucose levels -- whether caused by diabetes or other factors -- keep heart cells from maturing normally.

Researchers find no signs of early-onset OA in radiographs of Dolly's skeleton

Original concerns that cloning caused early-onset osteoarthritis (OA) in Dolly the sheep are unfounded, say experts at the University of Nottingham and the University of Glasgow.

Bacterial colonization can function as a pacemaker for the intestine, study reveals

A new study, conducted at Kiel University (CAU) by a research team from the Cell and Developmental Biology (Bosch AG), reveals that bacterial colonization of the intestine plays a significant role in controlling peristaltic functions.

Bacteria in the intestine can play important pacemaker role in peristalsis

Spontaneous contractions of the digestive tract play an important role in almost all animals, and ensure healthy bowel functions. From simple invertebrates to humans, there are consistently similar patterns of movement, through which rhythmic contractions of the muscles facilitate the transport and mixing of the bowel contents.

UCR researchers elucidate how blood clots shrink

Blood clotting is the "Jekyll and Hyde" of biological processes. It's a lifesaver when you're bleeding, but gone awry, it causes heart attacks, strokes and other serious medical problems.

Video provides new look at natural process of platelet-driven blood clot contraction

The first view of the physical mechanism of how a blood clot contracts at the level of individual platelets is giving researchers from the Perelman School of Medicine at the University of Pennsylvania a new look at a natural process that is part of blood clotting.
