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.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
