Stereotypes could be what drive females away from the computer science fields according to a press release issued by the Univ. of Washington. Being a female, the first thing I think about computer scientists are men with beer bellies that stay up all night coding, have no social life, and play video games or watc Star Trek (and not the new movie, the old shows) religiously. According to a study done by researchers at the Univ. of Washington, these stereotypes are brought on by the appearance of the environment people work in.
Growing up I have heard all types of opinions on using animals for scientific research. There are the people who are purely against it, like one friend who would rather see prisoners be injected with experimental drugs than risk harming an animal. Or people who think testing on animals is a great starter. And, although conflicted in how I feel about this topic, I have begun to see the benefit animals bring to the world of science in general.
The one thing I enjoy after a day at work is a nice, long walk or jog. Once the endorphins kick in everything seems perfect. Anything that happened previously that may have stressed me out or affected me negatively gets wiped away, or at least decreases, and I get lost in the rhythm my feet make as they rush across the dark pavement of the road.
Physicists at UC Santa Barbara have made an important advance in quantum mechanics using a superconducting electrical circuit. The researchers showed that they could detect the quantum correlations in the results of measurements of entangled quantum bits, using a superconducting electrical circuit. The correlations are stronger than can be obtained using classical (non-quantum mechanical) physics, and according to the physicists, this illustrates that the oddities of quantum mechanics clearly extend to macroscopic systems.

Companies looking for chip-interconnect solutions for high-volume electronic products can choose from two major types: solder alloys and conductive epoxies. For high-temperature applications, however, researchers at Virginia Tech and NBE Technologies LLC (both of Blacksburg, Va.) believe neither choice is optimal. Steering away from gold, tin, or lead mixtures, these researchers developed nanoTach, a smooth viscous semiconductive nanomaterial paste designed to significantly improve performance and reliability above 175°C.
There is a pressing need for environmentally friendly and benign methods and materials to mitigate corrosion on aluminum, especially aircraft. Until recently, chromates were the only corrosion inhibitors used on aluminum aircraft. Unfortunately, chromates are also human carcinogens, but replacing them has been exceedingly difficult. Enter Deft’s Benign, Corrosion Inhibiting Aircraft Primers 02GN083, 02GN084, and 44GN098, developed by Eric Morris and Richard Albers at Deft, Inc. (Irvine, Calif.) and James Stoffer and Thomas O’Keef at the Univ. of Missouri-Rolla (Rolla, MO).
As nanotechnology-based research continues to boom, so do the challenges, among them effective imaging and characterization.
