A little anxiety can be a good thing when it comes to cancer symptoms according to researchers at Washington University School of Medicine in St. Louis. They report that people with low overall anxiety levels were more apt to ignore symptoms of rectal cancer for long periods of time, thereby delaying treatment. In contrast, people with at least moderate levels of anxiety tended to quickly recognize symptoms such as rectal bleeding as a sign of serious illness.
"Almost everyone has heard about people who had cancer symptoms long before they sought help. I was curious about the psychology behind this," says Stephen Ristvedt, Ph.D., assistant professor of medical psychology in psychiatry and investigator at the Siteman Cancer Center. "Most people assume the explanation is fear or denial or a reluctance to hear the ’C-word’ from a doctor. So, I was surprised to find those who are generally optimistic and unconcerned had the longest delays."
The study will be reported in the May 2005 issue of Psycho-Oncology and is currently available online at the journal’s web site.

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...
