A Mayo Clinic discovery about a protein known as Dynamin-2 has thrown conventional wisdom for a loop. Finding the protein on the centrosome, a minute structure near a cell’s nucleus, may lead to new strategies for stopping cancer growth.
The Mayo team, already known for discovering several families of dynamins, this time discovered them -- not on a membrane, as expected -- but on the unlikely centrosome which has no membrane. It was the last place they expected to find them, but the surprise finding offers a new lead in the fight against cancer.
"These findings provide us with a basic understanding of how normal and cancer cells are organized; how they divide and how they might grow and die -- which is an important part of cancer," says Mark McNiven, Ph.D., the cell biologist who led the Mayo Clinic research team’s investigation. "A lot of cancers, you could argue, don’t grow faster; they just don’t die. So this discovery will improve our understanding of this very relevant cellular process. It promotes understanding the cell at its most basic level, giving us a new layer of detail."

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
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:...

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...
