Brush, then squash. Remember those three words and that technique the next time you catch a mosquito dining on your arm or leg, and you’ll go a long way to protecting yourself from a potentially lethal parasitic micro-organism that may be in the mosquito, and is especially dangerous to those with weakened immune systems.
A study by Rutgers-Newark biology professor Ann Cali and others published in the New England Journal of Medicine in July indicates that microsporidia, a group of opportunistic single-celled micro-organisms that can invade and devour virtually any kind of human cell, may have entered and broken down the muscle tissue of a Pennsylvania woman when she crushed a mosquito over the site where it had been drawing blood. The woman later died as a type of microsporidia called B. algerae, known to reside in the tissues of mosquitoes, systematically consumed muscle fibers in her body, leaving the muscles unable to contract and respond to mental commands.
Cali, who serves as a consultant for the Centers for Disease Control (CDC) and the Armed Forces Institute of Pathology at Walter Reed Army Hospital, theorizes that the B. algerae in the mosquito may have been ground into the wound left by the insect’s hypodermic-like feeding tube. Mosquitoes secrete an anti-coagulant to keep blood from clotting as they drink, temporarily leaving a clear passage directly into the bloodstream.

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
