The rise of gene-edited embryos has raised a myriad of ethical questions. It involves altering DNA to prevent disease or even to choose specific traits using a method known as CRISPR. In 2018, Chinese ...

Humans have selectively bred animals and crops since the beginning of agriculture, but advances in biotechnology have provided genetic tools to select specific traits. First applied to animals in the ...

Spider silk—six times tougher than Kevlar and stronger than steel—has now been produced by an unexpected source. Spider silk is a biological protein fiber spun by spiders. Many of these fibers have ...

Thanks to great strides in fundamental research, biology is becoming ever more programmable. Two recent scientific advances show just how powerful the possibilities could be. The genetic modification ...

CAR T cells are patient-derived, genetically engineered immune cells. They are "living drugs" and constitute a milestone in modern medicine. Equipping T cells, a key cell type of the immune system, ...

It’s one small step for mice, one giant leap for mammoth-kind. Scientists endeavoring to “de-extinct” woolly mammoths through genetic modification have taken a meaningful step toward achieving their ...

For the first time and with the help of CRISPR technology: A new large-scale genetic modification method makes it possible to reveal the role and properties of duplicated genes in plants The ...

A genetic modification in the 'coat' of a brain infection-causing virus may allow it to escape antibodies, according to Penn State College of Medicine researchers. They say testing people for this and ...

This mechanism for conferring longevity across generations could also explain how other stress-adaptive traits are passed to offspring.

West Nile Virus is coming soon to a barbeque near you. Colorado health officials diagnosed the first case of the season late last month in La Plata County. Infected mosquitoes have been detected in ...

Researchers have determined whether a specific chemical modification of a protein that packages the genome called a histone affects gene activity and cell proliferation. Researchers have determined ...
