Uranium from coal flyash waste

A company Wildhorse is going to study extracting Uranium from coal flyash. From the 50 million tons/year of flyash that is generated in Europe, there is 100 to 300 ppm uranium. This would be 5,000 to 15000 tons of Uranium that could be recovered. The US generates over 100 million tons of flyash each year …

Discovery of first gene that specifically links calorie restriction to longevity

Loss of only one of the genes, a gene encoding the protein PHA-4, negated the lifespan-enhancing effect of calorie-restriction in worms. And, when researchers undertook the opposite experiment—by overexpressing pha-4 in worms—the longevity effect was enhanced. “PHA-4 acts completely independent of insulin/IGF-1 signaling and turns out to be essential for CR-mediated longevity,” says Panowski. “We …

H2CAR is unaffordable

Engineer-Poet analyzes the H2CAR proposal and shows why it is a misleading diversion from real solutions H2CAR is completely unaffordable. In the H2CAR paper, figures such as 239 billion kg/year of hydrogen from 58,000 km2 of solar PV panels are tossed off rather casually. These numbers bear deeper analysis than they receive. For instance, 58,000 …

Magnetically assembled Nanotube-Tipped Probe Developed

Improved cell by cell analysis is made possible as well as injecting drugs into active cells one at time. This development could be combined with improved versions of surgical microbots to achieve something very similar to the vision of nanobot cellular repair nanomedicine. Drexel University College of Engineering researchers have successfully developed carbon nanotube-tipped pipettes …
