How Back to the Future II's "old" make-up compares to actual aging

We still have two years before 2015, the year Back to the Future II revealed to us — including how stars Michael J. Fox, Lea Thompson and Thomas Wilson might age. How did the movie do in portraying their older selves? Turns out not too bad! Certainly more accurate than the public fax machines the movie imagined. » 8/08/13 1:40pm 8/08/13 1:40pm

Bees pay a steep price for that whole "perpetuating the species" thing

If you're going to be reborn as a worker bee, make sure you don't do it in the summer. That's the time of year when the queen bee demands the most jelly to feed her young, and once that work is done, bees typically die just two weeks later. But in winter, otherwise identical bees can live six to seven months, which… » 4/21/13 5:00pm 4/21/13 5:00pm

People who age prematurely could soon benefit from rejuvenation…

Humans age at different rates, as a result of various factors like lifestyle and genetics. Now, a new study from the ENGAGE Consortium suggests that people who age faster are at an increased risk of developing age-related diseases like heart disease, multiple sclerosis, and various cancers. The researchers suggest… » 3/29/13 3:40pm 3/29/13 3:40pm

Does the science of aging suggest we're 'programmed to die'?

In an effort to slow down — and even halt — the aging process, scientists are increasingly turning their attention to the various external and internal factors that give rise to it. As this new video by AsapSCIENCE shows, we're all slaves to a biological clock that's been ticking away since the moment we were born —… » 3/14/13 6:20am 3/14/13 6:20am

Transplanted Brain Cells Can Outlast The Body's Biological Clock

The problem with cells is that they have an expiry date. They can only replicate so many times before they hit a biologically predetermined limit and sputter out. But a recent study by neuroscientist Lorenzo Magrassi from the University of Pavia in Italy shows that mammalian neurons are not subject to this kind of… » 2/26/13 8:00am 2/26/13 8:00am

Exercise may be the key to preventing brain shrinkage in old age

A research article published in Neurology found that people in their seventies who were more physically active showed less brain shrinkage over the course of three years. Unfortunately, socially and mentally stimulating situations didn't seem to have an effect, but something as simple as going for a walk a few times a… » 10/26/12 12:50pm 10/26/12 12:50pm

In just four generations, we’ve massively slashed human mortality

We're living longer — that's no surprise. But what is astonishing is just how much longer we're living than our predecessors, and how short of a time it's taken to happen. According to new research in PNAS, the last four generations of humans have seen an improvement in mortality that outdoes any of the previous 8,000… » 10/19/12 7:50am 10/19/12 7:50am

Watch a man age 12 years in 8 minutes, thanks to 4,514 self-portraits

Oh, the joys of extreme long-term video projects. Photographer Noah Kalina — who previously (and famously) took a snapshot of himself once a day over six years — has tacked another six-point-five years onto this unfinished visual diary. It's a stark reminder that every single person on the planet drank an eensy bit… » 9/04/12 10:10am 9/04/12 10:10am

Giving an old bee a youngster's job causes brain rejuvenation

Researchers at Arizona State University have successfully reversed brain aging in honeybees, by giving them responsibilities that are typically handled by much younger members of the hive. The change in occupation appeared to trigger a series of youth-restoring chemical processes in the bees' brain —processes that… » 7/05/12 2:43pm 7/05/12 2:43pm
