Virtual biopsy probe system is 'almost perfect' in detecting precancerous polyps during colonoscopy

The newest generation of "virtual biopsy" colonoscopy probes being tested demonstrate that it might soon be possible to use such a device to determine whether a colon polyp is benign and not remove it for biopsy. Currently, all colon polyps are extracted during a colonoscopy and sent to a pathologist for examination, which adds time, expense, and some surgical risk, to the...

Sticky environmental problem with carpet tiles solved

A new adhesive for use in carpet tiles could help dramatically reduce their impact on the environment. The powerful adhesives currently used to bind the layers of carpet tiles together make it challenging to recycle them. In Europe, around 70 million kilograms of carpet tile waste is incinerated or sent to landfill sites every...

Detecting fake wine vintages: It's an (atomic) blast

Two decades of atomic bomb testing in the atmosphere are yielding a new test to determine whether that Bordeaux or burgundy really is from a vintage year and a commands premium price or actually is a counterfeit vin ordinaire or cheap plonk worth much less.

H1N1: Infrared thermal detection systems useful for patient screening

Researchers found an Infrared Thermal Detection System (ITDS) to be a fast and effective fever screening tool in clinical settings during the H1N1 influenza pandemic. The ITDS detected fever in patients through split-second, non-contact skin temperature measurements. Fever is a primary symptom of seasonal influenza, H1N1, avian influenza, SARS and other infectious...

Environmental refugees and global warming

Climate change and environmental degradation are likely to trigger increased migration in Sub-Saharan Africa with potentially devastating effects on the hundreds of millions of especially poor people, according to a new article.

Rapid increases in tree growth found in US

Rapid increases in tree growth in the US, slower tree growth in the tropics, new ideas about biodiversity, new methods for monitoring forest carbon stocks: These are among the mid-term results from the HSBC Climate Partnership.

Key predictor of cardiovascular death identified

Coronary artery disease (CAD) hospitalizes more than 160,000 Canadians every year, and almost one quarter of those patients die from this common form of heart disease. But now researchers have identified a key predictor of mortality in CAD patients, which means that specialists can better determine how to treat and improve outcomes for patients with...

Beluga sturgeon in Caspian Sea reclassified as 'critically endangered'

Beluga sturgeon in the Caspian Sea have been reclassified as "critically endangered" placing them on IUCN's Red List, providing strong evidence that fishing and international trade should be halted and a stock-rebuilding plan should be initiated immediately. Beluga sturgeon populations have been decimated in part due to unrelenting exploitation for black caviar -- the sturgeon's unfertilized eggs...

Mastery of rare-earth elements vital to America's security

Used in everything from batteries to electric motors, rare earth elements are vital to America's security, a senior metallurgist at the US Department of Energy's Ames Laboratory, told members of the Investigations & Oversight Subcommittee of the House Committee on Science and Technology. Yet, the great majority of rare earth mining and production currently takes place in...

Health-care worker vaccination rates remain perilously low

Health-care personnel influenza immunization rates have remained low, despite recommendations from the Centers for Disease Control and Prevention and other leading health-care organizations that all health-care personnel receive annual flu vaccines. Experts say these levels are perilous. Increasing vaccination rates substantially improves patient safety, lowering flu deaths by 40...

A more sensitive sensor

Scientists have set out to make sensors for microelectromechanical systems significantly more sensitive and reliable than they are today, shrinking their work to nano-size to do it.
