Taking Aim With Nanoparticle PEBBLEs

...t reactive oxygen species into it, setting off "an avalanche of damage," said Kopelman. By staying outside the cell, PEBBLEs avoid a problem that thwarts many chemotherapy drugs. "The really bad cancer cells get immune to chemotherapy drugs ?they pump the drugs back out," Kopelman said. Cancer cells can't do ...

Tiny avalanche photodiodes target bioterrorism agents

... for Quantum Devices have demonstrated solar-blind avalanche photodiodes (APDs) that hold promise for universal...to realize high-quality AlGaN so as to demonstrate avalanche gain in the solar-blind region. Northwestern's results were presented recently by Razeghi at the AP...

UT Southwestern researchers discover master switch in cell death

...al Cell. The life and death of cells is a complex avalanche of reactions, controlled by a few molecules that sit atop a biochemical “pyramid.?/p> The newly discovered enzyme, which the researchers have named Mule, destroys a key molecule at the top of the pyramid, thus leading to the cascading disintegrat...

Stanford/Packard scientist's data-mining technique strikes genetic gold

...clinically useful nuggets will be buried under the avalanche of data inundating international repositories each year unless scientists come up with a way to better classify their experiments and results. "Libraries figured out a long time ago how to classify items using the Dewey decimal and other systems," s...

Antarctic icebergs -- Hotspots of ocean life

... data brought new challenges in how to manage this avalanche of information. “The whole is definitely greater than the sum of the parts, and to answer questions across the different areas from ecology to chemistry and climate, scientists need access to all the data,” explained researcher John Helly of the San ...
