Scientists at the San Diego Supercomputer Center (SDSC) at UCSD analyzing traffic to one of the 13 Domain Name System (DNS) “root” servers at the heart of the Internet found that the server spends the majority of its time dealing with unnecessary queries. DNS root servers provide a critical link between users and the Internet’s routing infrastructure by mapping text host names to numeric Internet Protocol (IP) addresses. Researchers at the Cooperative Association for Internet Data Analysis (CAIDA) at

Recent research shows that insects and humans have something surprising in common: Some six-legged species take in oxygen using a similar means to the way we fill our lungs.

Scientists from the Field Museum and Argonne National Laboratory in Chicago and from Clemson University used a powerful x-ray imaging device to get the first comprehensive view of live insects breathing. Their observations and research results are reported in the Jan. 24 issue of Science, an internationally respected res

Understanding how mountains form is critically important — from volcanic eruptions to earthquakes to catastrophic mudslides, the geologic processes active in mountain belts affect human societies every day. Yet, even though mountains are on all continents and in all ocean basins, scientists still understand relatively little about the forces that interact to form and destroy mountains, how mountains change over time, and the relationship between mountains and Earth’s climate.

Video cameras are used to keep an eye on many indoor and outdoor locations, but to pinpoint suspicious activity, human security guards or intelligence analysts have the unenviable task of watching dozens of video monitors or many hours of recorded video.

Supported by an NSF award, Jezekiel Ben-Arie and his students at the University of Illinois at Chicago have developed a technique, much faster and more reliable than previous methods, that allows a computer to recognize a human action contai

Oxford University researchers have devised a novel coil design for magnetic resonance (MR) application, devised specifically for deep organ MR where sensitive imaging and spectroscopy have been previously difficult.

Deep organ magnetic resonance requires maximised sensitivity and magnetic field homogeneity over a relatively large field of view (FOV). However, it is difficult to maximise both sensitivity and magnetic field homogeneity simultaneously. The sensitivity can be maximised by reduci

Stress at work and fatigue increase the chance of acute infections such as common colds, flu-like illnesses and gastroenteritis. This was discovered in research carried out by Danielle Mohren at Maastricht University, in which more than 8000 employees from various companies were followed over a three-year period.

The study revealed that employees in highly demanding jobs suffered from colds 20 percent more often than employees in less demanding positions. Also job insecurity, for example as
