Festival draws half a million fans of science and engineering

The scene was a sea of white tents spread across the National Mall in Washington, DC and science and engineering were the order of the day. That's what greeted visitors to the booth hosted by Johns Hopkins Institute for NanoBioTechnology at the first USA Science and Engineering Festival Expo.

A new electromagnetism can be simulated through a quantum simulator

One of the best quantum simulators consists of a gas of extremely cold atoms loaded in an artificial crystal made of light: an optical lattice. Experimental physicists have developed efficient techniques to control the quantum properties of this system, to such extent, that it serves as an ideal quantum simulator of different phenomena.

The physics of coffee rings

Researchers have devised a predictive model that combines laboratory studies of microscopic glass particles in solution with mathematical theories to predict the existence, thickness and length of the banded ring patterns that formed.

Methane-powered laptops may be closer than you think

Making fuel cells practical and affordable will not happen overnight. It may, however, not take much longer. With advances in nanostructured devices, lower operating temperatures, and the use of an abundant fuel source and cheaper materials, a group of researchers led by Shriram Ramanathan at the Harvard School of Engineering and Applied Sciences (SEAS) are increasingly optimistic about the commercial viability of the technology.

Magnetic field directs nanoparticles to tumors

To improve the tumor-specific delivery of drug to tumors, a team of investigators has created a system of nanoparticles-within-a-nanoparticle that can be directed to and concentrated at the site of tumor using a magnetic field. Once at the tumor site, radiofrequency irradiation triggers drug release from the nanoparticles, bathing the tumors in drug and markedly reducing the growth of the tumors.
