Could computers reach light speed?

Trapped light waves go farther than expected, giving insights on designing computer circuit interconnects that work at nearly the speed of light.

Spiraling laser pulses could change the nature of graphene

A new study predicts that researchers could use spiraling pulses of laser light to change the nature of graphene, turning it from a metal into an insulator and giving it other peculiar properties that might be used to encode information.

Magnetization dynamics in a checkerboard optical lattice

Scientists studied the magnetic and motional dynamics of atoms in a specially designed laser-based lattice that looks like a checkerboard.

A foundation for nanotechnology education

The Nanotechnology Applications and Career Knowledge Network initiated the development of two new standards: Guide for Workforce Education in Nanotechnology Health and Safety, and Practice for Workforce Education in Nanotechnology Characterization.

bioresorbable electronic stent could provide feedback and therapy - then dissolve

Scientists a new kind of multi-tasking stent that could minimize the risks associated with a procedure to unblock clogged arteries. It can sense blood flow and temperature, store and transmit the information for analysis and can be absorbed by the body after it finishes its job.

Nanotechnology helps protect patients from bone infection

Scientists have discovered nanotechnology could hold the key to preventing deep bone infections, after developing a treatment which prevents bacteria and other harmful microorganisms growing.

Physicists solve quantum tunneling mystery

An international team of scientists studying ultrafast physics have solved a mystery of quantum mechanics, and found that quantum tunneling is an instantaneous process.

Nanosilver and the future of antibiotics

Precious metals like silver and gold have biomedical properties that have been used for centuries, but how do these materials effectively combat the likes of cancer and bacteria without contaminating the patient and the environment?

Linking superconductivity and structure

Superconductivity is a rare physical state in which matter is able to conduct electricity without any resistance. It can only be found in certain materials, and even then it can only be achieved under controlled conditions of low temperatures and high pressures. New research hones in on the structural changes underlying superconductivity in iron arsenide compounds - those containing iron and arsenic.

Experiments in the realm of the impossible

Physicists simulate for the first time charged Majorana particles - elementary particles, which are not supposed to exist.
