The researchers reported that the test detected 98 percent of all cancers A new noninvasive test for colorectal cancer screening demonstrated high sensitivity for detecting colorectal cancer, in particular precancers that are most likely to develop into cancer, according to data presented at the 11th Annual AACR International Conference on Frontiers in Cancer Prevention Research,

Rodents sacrifice sweets to jailbreak their friends   According to a study published in the December 9, 2011, issue of Science, rats can be surprisingly selfless. University of Chicago neuroscientist Peggy Mason and psychologists Inbal Ben-Ami Bartal and Jean Decety placed pairs of rats in pens. One rat was caged in the middle of the

The world has little use – and precious little time — for detached experts. A group of scientists – each of them experts – makes a compelling case in this week’sScience Magazine that the growing global challenges has rendered sharply segregated expertise obsolete. Disciplinary approaches to crises like air pollution, biodiversity loss, climate change, food

A commercially available particle trap can filter microscopic pollutants in diesel-engine exhaust and prevent about 98 percent of them from reaching the air, according to research reported in Circulation: Journal of the American Heart Association. Inhaling exhaust particles increases the risk of dying from heart and lung diseases. Air pollution, including diesel exhaust as a major

A multidisciplinary team of researchers led from Karolinska Institutet in Sweden have developed an anti-inflammatory drug molecule with a new mechanism of action. By inhibiting a certain protein, the researchers were able to reduce the signals that trigger an inflammation. The study is published in Science and was done in collaboration with the University of

Advanced cyberwar is different THE decision by the United States and Israel to develop and then deploy the Stuxnet computer worm against an Iranian nuclear facility late in George W. Bush’s presidency marked a significant and dangerous turning point in the gradual militarization of the Internet. Washington has begun to cross the Rubicon. If it

“This new technology could get us over the hump and make solar energy cost-competitive with fossil fuels,” says Willis. “This is brand new technology, a whole new train of thought.” A novel fabrication technique developed by UConn engineering professor Brian Willis could provide the breakthrough technology scientists have been looking for to vastly improve today’s

Researchers at the University of Sheffield have developed a method of sourcing obsidian artefacts that takes only 10 seconds – dozens of times faster than the current methods – with a handheld instrument that can be used at archaeological excavations. Obsidian, naturally occurring volcanic glass, is smooth, hard, and far sharper than a surgical scalpel

Using a technique that creates a new nanoscale architecture, researchers have created an aluminum alloy just as strong as steel but with reasonable plasticity to stretch and not break under stress. Importantly, the technique of creating these nanostructures can be used on many different types of metals and the team plans to work on strengthening

The creators of a unique kit containing anatomical body parts produced by 3D printing say it will revolutionise medical education and training, especially in countries where cadaver use is problematical. The ‘3D Printed Anatomy Series’, developed by experts from Monash University, is thought to be the first commercially available resource of its kind. The kit
