The Fraud of Agriculture
Scholars once proclaimed that the agricultural revolution was a great leap forward for humanity. They told a tale of progress fuelled by human brain power.Evolution gradually produced ever more intelligent people. Eventually, people were so smart that they were able to decipher nature’s secrets, enabling them to tame sheep and cultivate wheat. As soon as this happened, they cheerfully abandoned the gruelling, dangerous, and often spartan life of hunter-gatherers, settling down to enjoy the ...05 FEB 2016 by ideonexus
The Stress of Cold Temperatures Extends Lifespans
In 1986, John Holloszy of Washington University immersed his lab rats in shallow, cool water for four hours each day. They burned so many extra calories that they ate half again as much as control rats, but weighed less. The cold rats lived 10% longer, on average. Holloszy framed his report on this experiment not as a hormetic effect of cold exposure, but as a refutation of the “rate of living” hypothesis. In 2006, Gordon Lithgow of the Buck Institute for Aging Research exposed lab worms...Folksonomies: longevity

The Unmentioned Trade-Offs in Life Extention
Now it is not that the cell biologists can’t point to experiments which seem to fit their views, as is common in natural science. (After all, the Earth’s Moon does indeed have a geocentric orbit.) Good colleagues of mine like Robert Reis are able to produce nematode worms that live ten times longer than their unmutated controls, if they use ingenious genetic and environmental manipulation. But nematodes have well-developed physiological machinery for sustaining states of metabolic arrest,...From Michael R. Rose's "Immortalist Fictions and Strategies"

Call for Nitrogen Fixation
England and all civilised nations stand in deadly peril of not having enough to eat. As mouths multiply, food resources dwindle. Land is a limited quantity, and the land that will grow wheat is absolutely dependent on difficult and capricious natural phenomena... I hope to point a way out of the colossal dilemma. It is the chemist who must come to the rescue of the threatened communities. It is through the laboratory that starvation may ultimately be turned into plenty... The fixation of atmo...Crookes predicts the failure of farming to support a growing population and calls on chemists to work on improving production.
