Trusting the Future? Ethics of Human Genetic Modification

Taboos are an interesting social construct. Every culture tends to regard their own as both inviolable and immutable, but history begs to disagree. It's commonplace for societies to hold as absolute their understanding of what is right and moral and necessary, and to resist the notion that these convictions are, or should be, subject to…

New Genetic Test Reveals Your Ancestral Origin

  For centuries, scientists have sought a biological method for tracing a person's geographic origin. Now, a group of researchers has developed such a genetic ancestry test that can pinpoint the location where a person's ancestors originated more than 1,000 years ago. The genetic algorithm accurately predicts the country of ancestral origin for about 80…

Impact glass from asteroids and comets stores biodata for millions of years

Bits of plant life encapsulated in molten glass by asteroid and comet impacts millions of years ago give geologists information about climate and life forms on the ancient Earth. Scientists exploring large fields of impact glass in Argentina suggest that what happened on Earth might well have happened on Mars millions of years ago. Martian…

Living organ regenerated for first time: Thymus rebuilt in mice

A team of scientists at the University of Edinburgh has succeeded in regenerating a living organ for the first time. The team rebuilt the thymus -- an organ in the body located next to the heart that produces important immune cells. Immune repair The advance could pave the way for new therapies for people with…

Tiny, Logical Robots Injected into Cockroaches

Nanotechnology just got a little bit smarter. At the Institute of Nanotechnology and Advanced Materials at Israel's Bar-Ilan University, Ido Bachelet led a team of scientists in building tiny robots that can respond to chemical cues and operate inside a living animal. More than that, they can operate as logic gates, essentially acting as real…

A Cure for Ageing? David Sinclair talks about the fight against aging

Can we really cure ageing? David Sinclair thinks so, and he's going to try to prove it. David Sinclair is a scientist and entrepreneur working on increasing human health, productivity, and lifespan. After co-discovering a molecular cause of aging at the Massachusetts Institute in Boston in the mid-1990s, he joined the faculty of Harvard Medical…

BIOESSAYS: Why do the well-fed appear to die young?

Dietary restriction adaptively up-regulates cellular recycling mechanisms (e.g. autophagy, apoptosis) to increase resource efficiency and promote immediate reproduction. Old-age pathologies, such as cancer, are reduced as a side effect, extending lifespan in benign laboratory environments. Such benefits are unlikely to translate to the wild, where extrinsic mortality risk is high. In this video, Margo Adler…
