Researchers at Washington University School of Medicine in St. Louis have developed a new probe that allows them to watch protein activity in living cells. In their initial study, which focused on a protein tentatively linked to the spread of cancerous cells, the team both proved their new technique works and revealed surprising new details about the protein’s activity.
The protein in this study, neuronal Wiskott–Aldrich syndrome protein (N-WASP), is naturally found in every cell in the body and is known to be involved in a wide range of cellular processes. One of its key functions is believed to be guiding cellular growth and movement within the body, including when tumor cells metastasize, or spread, from one organ to another.
“To our knowledge this is the first probe of its kind that allows us to actually see in a living system where, when and how proteins are activated,” says first author Michael E. Ward, a graduate student in anatomy and neurobiology. “This is significant progress in moving from examining the biochemistry of ground up cells to being able to study it in an intact cell.”

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
