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.

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,...
