The Future of Immortality
Biomedical gerontologist Aubrey de Grey wants to reverse the aging process, enabling people to lead long, very long, active lives. He believes immortality is within our grasp.
What's the Latest Development?
In an interview given in Cambridge, England, gerontologist and advocate of anti-aging science Aubrey de Grey says that immortality is within our grasp, possibly even within his lifetime: "I focus on the fact that every day that I bring the defeat of aging forward, I'll have saved 100,000 lives (that's the number of people who die every day at present from causes that young adults rarely die of). That's pretty good motivation, whether or not I'm one of the people in question." While de Grey gives about 50 lectures a year, the hard science behind his speculations can be found in his book, Ending Aging.
What's the Big Idea?
As a society, is immortality something we should wish for? In response to concerns about overpopulation, should be we all live to be 200, de Grey says: "There are plenty of ways to keep population down even if we don't let old people get sick—we could kill every other baby, for example. I hope you see my point: old people are people too. If we reject ageism, we are, inescapably, morally obliged to do our best to keep them healthy just as we do for the young, both by applying existing medicine and by developing medicine that does not yet exist."
How a cataclysm worse than what killed the dinosaurs destroyed 90 percent of all life on Earth.
While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.
A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.
We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.
Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.
Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
