Mouse egg cells made entirely in the lab give rise to healthy offspring

Mouse egg cells made entirely in the lab give rise to healthy offspring

In work that raises the prospect of new infertility treatments and designer babies, researchers have used stem cells to grow fertile mouse egg cells for the first time entirely in a lab dish. The eggs gave rise to pups after being fertilized and implanted into rodent foster mothers. The method—which sometimes produced defective eggs and […]

No sweet surrender: Glucose actually enhances self-control, study shows

In the age of the ‘sugar tax’, good news about glucose is hard to come by. But an Australian scientist has just proposed a new understanding of the established link between the sweet stuff and improved self-control.

Zika virus directly infects brain cells and evades immune system detection, study shows

The mosquito-borne Zika virus linked to microcephaly and other neurological problems in newborns of affected mothers directly infects the brain progenitor cells destined to become neurons, UT Southwestern Medical Center researchers report in a study published online in Cell Reports. The team of researchers used a strain of Zika currently impacting the Americas, and found […]

Human Embryos Grown In Lab For Record Period Of Time

Human Embryos Grown In Lab For Record Period Of Time

Researchers have managed to keep a human embryo alive in the lab for a record period of time, moving past the point when they would naturally implant into the womb, and surviving just short of the number of days scientists are legally able to grow them for. For 13 days the researchers were able to […]

An experimental Alzheimer’s drug reverses genetic changes thought to spur the disease

Aging takes its toll on the brain, and the cells of the hippocampus—a brain region with circuitry crucial to learning and memory—are particularly vulnerable to changes that can lead to Alzheimer’s disease or cognitive decline. With the hope of counteracting the changes that can lead to these two conditions, researchers at Rockefeller University and their […]

There’s a deadly fungus spreading among snakes in the United States. But don’t cheer. As much as snakes might frighten us, they’re important players in the ecosystem, and we really don’t want to lose them. In 2006, scientists discovered some odd skin infections among snakes in declining populations in New Hampshire. Soon after, fungal infections […]
