Perhaps, bioterrorists will not be able to spread lethal bacteria of anthrax in envelopes all over the world. Siberian biologists and physics have thought up how to adapt electron accelerator that is usually used for sterilizing medical equipment for decontamination of letters. To optimize the power of the accelerator they calculated how many bacteria could get into a human body when touching the letter infected and how many bacteria should be destroyed to avoid the tragedy.
For their experiment the scientists chose two bacteria species that form almost ineradicable spores. Both species were genetically close to anthrax. One of them is a harmless inhabitant of soils whereas the other causes a disease in insects. Its spores in the mixture with the powdered mineral kaolin can be used as insecticide.
When imitating the probable actions of mail terrorists the scientists made 60 paper packets with the sides of 50 and 25 millimeters and poured a quarter of a gram of sterile kaolin. Then several drops of suspension, which contained 10 million spores per one milliliter, were added into each packet and intensively mixed with kaolin. Then the packets were dried at 70 C and put into envelopes.

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...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
