The authors show that early removal of senescent cells in the retina protects the healthy retinal ganglion cells from death to maintain vision. These data suggest the potential application of senolyt…
The red giant Betelgeuse is the dimmest seen in years, prompting some speculation that the star is about to explode. Here’s what we know.
In terms of the number and scale of its success stories, the 2010s have a good claim for being the greatest 10 years in the history of artificial intelligence. What were the biggest advances in A.I. over the past decade? Digital Trends takes a trip down recent memory lane.
It was found along the side of a road in a remote Australian gold rush town. In the old days, Wedderburn was a hotspot for prospectors – it occasionally still is – but nobody there had ever seen a nugget quite like this one.
The Wedderburn meteorite, found just north-east of the town in 1951, was a small 210-gram chunk of strange-looking space rock that fell out of the sky. For decades, scientists have been trying to decipher its secrets, and researchers just decoded another.
In a study published in August this year, led by Caltech mineralogist Chi Ma, scientists analysed the Wedderburn meteorite and verified the first natural occurrence of what they call ‘edscottite’: a rare form of iron-carbide mineral that’s never been found in nature.
Sending construction robots into outer space will help pave the way for human exploration, but there are some real challenges that lie ahead.
In the life extension movement, longevity escape velocity (sometimes referred to as Actuarial escape velocity[1]) is a hypothetical situation in which life expectancy is extended longer than the time that is passing. For example, in a given year in which longevity escape velocity would be maintained, technological advances would increase life expectancy more than the year that just went by.
Life expectancy increases slightly every year as treatment strategies and technologies improve. At present, more than one year of research is required for each additional year of expected life. Longevity escape velocity occurs when this ratio reverses, so that life expectancy increases faster than one year per one year of research, as long as that rate of advance is sustainable.[2][3][4]
The concept was first publicly proposed by David Gobel, co-founder of the Methuselah Foundation (MF). The idea has been championed by biogerontologist Aubrey de Grey[5] (the other co-founder of the MF), and futurist Ray Kurzweil,[6] who named one of his books, Fantastic Voyage: Live Long Enough to Live Forever, after the concept. These two claim that by putting further pressure on science and medicine to focus research on increasing limits of aging, rather than continuing along at its current pace, more lives will be saved in the future, even if the benefit is not immediately apparent.[2].
