A new multi-university study shows that research to delay aging and the infirmities of old age would have better population health and economic returns than advances in individual fatal diseases such as cancer or heart disease.

With even modest gains in our scientific understanding of how to slow the aging process, an additional 5 percent of adults over the age of 65 would be healthy rather than… read more

If there were time travelers among us, how would you find them?

That question occurred to astrophysicist Robert Nemiroff, a professor at Michigan Technological University. So he and his team developed a search strategy based on what they call “prescient knowledge.”

If they could find a mention of something or someone on the Internet before people should have known about it, that could indicate that whoever wrote it… read more

Rabbits with blocked windpipes have been kept alive for up to 15 minutes without a single breath, after researchers injected oxygen-filled microparticles into the animals’ blood, Nature News reports.

The development is reminescent of a hypothetical concept called respirocytes proposed by Robert A. Freiatas, Jr. —  microscopic, artificial red blood cells that can emulate the function of its organic counterpart, only with 200 times the efficiency, so as to supplement… read more
