By studying a little-known yeast too primitive to get diseases, Johns Hopkins researchers have uncovered a surprising link between two processes at play in heart disease and cancer in people.
In experiments with yeast known as S. pombe, the researchers discovered that a gene that helps the organism make cholesterol also helps it survive when oxygen is scarce. The finding, described in the March 25 issue of Cell, offers a new strategy for killing infectious yeast, but it also suggests that cells efforts to make cholesterol and detect oxygen levels might be connected in people, too.
"We were simply trying to establish that this yeast could be a model for studying cholesterol-related activities in human cells," says the studys leader, Peter Espenshade, Ph.D., assistant professor of cell biology in Johns Hopkins Institute for Basic Biomedical Sciences. "We certainly didnt expect to find a completely new role for this gene."

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...
