Amphidinolides, a family of natural compounds that have shown promise as powerful antitumor agents, pose problems for cancer researchers because they are found in only minute amounts, and only in microscopic marine flatworms that live off the coasts of Japan and the U.S. Virgin Islands. Nature keeps a tight lock on its supply of amphidinolide.
Work by University of Illinois at Chicago chemistry professor Arun Ghosh may solve this problem. Hes successfully developed a way to synthesize amphidinolides, making potentially abundant quantities available for cancer research. Ghosh and doctoral student Chunfeng Liu reported on their technique in the Feb. 6 online edition of the Journal of the American Chemical Society.
"We wanted to synthesize amphidinolide in the laboratory for subsequent biological studies," said Ghosh. As an antitumor agent, "nobody knows its exact mechanism of action. It could be a microtubule stabilizing agent, like Taxol, or it could cause cellular apopotosis, where cancer cells are killed by chemotherapeutic agents," he said.

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.

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...
