Assistant Professor Julia Kubanek and her colleagues at the Scripps Institution of Oceanography have investigated a seaweed called Lobophora variegata (see below) and discovered it has a strong antifungal potency and potentially some cancer-fighting power.

Scientists have discovered that seaweeds defend themselves from specific pathogens with naturally occurring antibiotics. The finding helps explain why some seaweeds, sponges and corals appear to avoid most infections by fungi and bacteria, according to a study published May 19 in the Proceedings of the National Academy of Sciences.
“Seaweeds live in constant contact with potentially dangerous microbes, and they have apparently evolved a chemical defense to help resist disease,” said lead author Julia Kubanek, an assistant professor of biology and chemistry at the Georgia Institute of Technology in Atlanta. “These plants have a really effective way of defending themselves.”
Few studies have addressed disease resistance in seaweeds, and seaweed diseases are little understood, except for species that are commercially important – for example, the seaweed used for sushi. This study’s report of isolating a potent antifungal compound contained in the common seaweed species Lobophora variegata reveals an unusual chemical structure not seen before in plants.

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...
