The probability of acute appendicitis is very low if there is no distinctly apparent appendix on the CT scan, and in the absence of any secondary CT signs of appendicitis, says a study by researchers from the Northwestern University Feinberg School of Medicine and Northwestern Memorial Hospital in Chicago.
For the study, the researchers analyzed the CT scans of 366 patients with abdominal pain who were referred to rule out the diagnosis of appendicitis. In 46 of the patients, the appendix was not visible on the scan. After further tests or follow-up, the researchers found that only one of those 46 patients actually had acute appendicitis.
Usually, if a physician cannot see the patients appendix on the CT scan, the physician might recommend further investigation or observation because he or she would not be able to rule out acute appendicitis, according to Paul Nikolaidis, MD, lead author of the study. "The findings of this study might provide information to change that course of action," said Dr. Nikolaidis.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
