The world's population is expected to hit 10 billion this century. Future widespread hunger is a palpable fear. New research shows that it need not be.
Some scientists believe that humanity's best shot at colonizing other planets lies in working within existing physics using organisms -- in this case, bacteria encoded with human DNA -- that can survive the trip.
Using data from one of the world's oldest continuing studies of aging men, researchers have discovered a possible connection -- in the form of a certain type of gene -- between body height and lifespan.
In mice, the answer seems to be yes: Recent studies reveal improvements in memory and brain cell growth in older mice who received blood or plasma from younger mice.
UCLA researcher Steve Horvath has come up with a way to measure the biological -- rather than chronological -- age of human organs, tissues and cells. His findings could lead to new ways to slow or even stop aging.
Researchers at the Netherlands' Leyden Academy on Vitality and Aging admit to being "baffled" by the findings of a study that focused on citizens in 19 developed countries, including the US.
The company has announced the launch of Calico, which will most likely take advantage of Google's formidable search tools to help put more focus on aging and related diseases.
A Pew Research Center survey released this week revealed that despite Americans' optimism about advances in medical technology, a slight majority said they wouldn't want to have their lifespans extended past 120 with such technology.
We have made enormous advances beyond the nasty, brutish and short 20 years or so of life that our Neolithic ancestors endured. So what will it take for all of us to live to 100?
Is there any reason to avoid death? We all die eventually, but is it a destiny sealed in for a predetermined time, or do we actually have some control over how long we are on this Earth?
Scientists of all stripes have for years investigated the proclivities and behaviors of our primate cousins in order to gain insight into human behavior, and a recent study of rhesus macaques has added two more shared traits: the enjoyment of pornography and the worship of celebrities. Here’s ...
Once they’re gone, mammalian arms and legs can't ever be restored. But if you cut off a salamander's leg it will reappear in just a few weeks. The enigma of amphibian organ regeneration has long puzzled scientists. Now, a new wave of scientists hopes to put it to use.
In the 21st century, biology will usher in advances in regenerative medicine. Stem cells will be at the center of discovery and application in that new field.
“We are at the cusp of a revolution in medicine and biotechnology that will radically increase not just our life spans but also, and more importantly, our health spans," says Sonia Arrison, author of 100: How the Coming Age of Longevity Will Change Everything.
