What's the Real Radiation Risk of the TSA's Full Body X-Ray Scans?
It’s not like this week was the first appearance of the full-body X-ray scanners in American airports. Yet, thanks to the looming holiday travel season, leaked X-ray images that were supposed to be kept private, and high-profile rebellion by pilots ...
How kinesin actually moves
A kinesin molecule takes one 8-nanometer “step” along a microtubule for every high-energy ATP molecule it uses, and it uses about 80 ATPs per second. On the scale of a living cell, this movement is very fast. To visualize it on a macroscopic scale ...
Joule Unlimited: 'Fuel from thin air' comes closer, clearer
In Massachusetts, the secretive Joule Unlimited (then known ... that is converted into ATP via an endogenous or exogenous ATPase. “In a preferred embodiment, the cell is engineered such that the final product is released from the cell.
The Daily Bucket - a Different View of Yellowstone
The Old Faithful area was my backyard when I worked summers in the park during my college ... the process of alkaline hydrolysis, the natural breakdown of materials at high pH levels, and the use of thermophilic gene products to create biofuels.
XpsE oligomerization triggered by ATP binding, not hydrolysis, leads to its association with XpsL
While isolated XpsE exhibits very low intrinsic ATPase activity, association with XpsL appears to stimulate ATP hydrolysis. Mutation at a conserved lysine residue in the XpsE Walker A motif causes reduction in its ATPase activity without significantly ...
