A 360 J laser pulse transmutes an isotope with a half-life of 15.7 million years into a lighter isotope with a half-life of just 25 minutes.

The optoelectronic properties of palladium oxide nanoparticles embedded in a titanium oxide matrix could be used to kill bacteria and power electronic devices, say researchers.

Mammography is currently the gold standard in breast imaging, and it is used to screen millions of women each year for breast cancer. It has its limitations, however, and lately there has been much interest in emerging breast-imaging technologies. Now, a group from the University of Manitoba in Winnipeg, Canada, has come up with an idea that could significantly improve the sensitivity of X-ray-based breast-imaging modalities, such as traditional mammography or CT mammography, without increasing the radiation dose (Medical Physics 34 256).
