Researchers know that the many different roads to cell suicide all run through mitochondria, but do not know which roads are the ones most traveled by the signals that signify death
The story of how mitochondria are recruited during times of stress to choreograph apoptosis--the cells dance of death--is a story that fails to tell which particular set of steps the cells use most often, according to investigators at St. Jude Childrens Research Hospital and the La Jolla Institute of Allergy and Immunology (San Diego, CA).
Mitochondria are sacs of enzymes in the cell that extract energy from food and store this energy in the high-powered chemical bonds of molecules called ATP. Virtually all activity of cells requires energy supplied by ATP, which acts as the "currency" with which the cell "buys" chemical reactions.
The fact that more than 100,000 research papers on apoptosis have been published is ironic, since this vast amount of information contributes to the confusion over which signaling pathways are most important for triggering this process, according to Douglas R. Green, Ph.D., chair of Immunology at St. Jude and holder of the Peter C. Doherty Endowed Chair of Immunology. Green is senior author of an editorial on apoptosis that appears in the October 7 issue of Science.

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...
