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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
