In the article, C&EN News Editor William G. Schulz points out that bedbugs represent a growing epidemic that is difficult to control. The bugs hide in mattresses, box springs, nightstands, and other areas, emerging at night to dine on human blood.
Their bites can cause allergic skin reactions, mental anguish, and loss of sleep. Infestations can be a financial burden, with professional extermination sometimes costing thousands of dollars and taking eight weeks or more. Some chemicals that were once effective against the pests, such as DDT, have been banned due to threats to human health and the environment, leaving exterminators with few effective options for controlling the pests, which have developed the ability to shrug-off some pesticides.
But the fight against bedbugs is intensifying. Scientists are looking for new substances to fight bedbugs that are safe and effective. Officials in Ohio — "bedbug ground zero' — are seeking Federal government permission to resume use of a pesticide called propoxur that can quickly halt infestations. Propoxur was pulled from the market by its manufacturer after EPA raised safety and efficacy concerns. For now, a combination of pesticides and preventive measures, such as regular inspection, laundering, vacuuming, removing clutter, and sealing up cracks in walls and baseboards, are among the best ways to control the bugs, the article notes.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
