Work climate the main reason women leave engineering, survey suggests

March 10th, 2011
After years of investing in strategies to encourage more women to pursue a rigorous engineering degree -- and succeeding -- US engineering firms are now facing a problem in retaining qualified women engineers. Why are so many women leaving the field -- or getting their degrees but never entering the field? The top reason isn't family, according to a new study, but an unfavorable work climate.

Tiny gems take big step toward battling cancer

March 9th, 2011
Researchers have now demonstrated the significance and translational potential of nanodiamonds in the treatment of chemotherapy-resistant cancers. In studies of liver and breast cancer models in vivo, the team found that a normally lethal amount of a chemotherapy drug when bound to nanodiamonds significantly reduced the size of tumors in mice. Survival rates also increased and no toxic effects on tissues and organs were observed.

Materials identified that may deliver more ‘bounce’

March 9th, 2011
Researchers have identified a class of high-strength metal alloys that show potential to make springs, sensors and switches smaller and more responsive. The alloys could be used in springier blood vessel stents, sensitive microphones, powerful loudspeakers, and components that boost the performance of medical imaging equipment, security systems and clean-burning gasoline and diesel engines.

New shapes of microcompartments: Molecular shells that encapsulate cellular components

March 4th, 2011
Researchers have discovered and explored new shapes of microcompartments, the molecular shells that encapsulate cellular components.

How voltage breaks down plastic: Creasing to cratering

March 4th, 2011
Scientists have seen for the first time how soft polymers, such as wire insulation, can break down under exposure to electrical current.

Cements that self-repair cracks and store latent heat energy?

March 2nd, 2011
Cement (and derivatives thereof) is one of the materials most commonly used in construction, given its good performance at low cost. Over recent years, one part of scientific and technological research is aimed at incorporating additional functions into these materials. Researchers have studied the possibility of adding capacities to the cement such as the self-repair of cracks as well as the storing of latent heat energy.

NASA readies for world’s largest can crusher test

March 1st, 2011
Place a soda can on the floor in an upright position and then stand on it -- gradually applying weight -- until the can ripples and collapses. It's similar to what a team of NASA engineers will do to an immense aluminum-lithium rocket fuel tank in late March; their hope is to use data from the test to generate new "shell-buckling design factors" that will enable light-weight, safe and sturdy "skins" for future launch vehicles.
