Life-giving technology: Camera pills and ultrasound creating maps of the body

For more than ten years, senior medical officer Ronald Marvik at St. Olav's Hospital in Trondheim has been collaborating with SINTEF scientist Thomas Lango. Together, they have created a new IT-base window on the inside of the body, a window that makes a patient transparent on a screen when a surgeon inserts operating instruments through small openings in the abdominal wall.

New biosensor could help the search for new drugs

Chalmers researcher Andreas Dahlin has developed a biosensor with an artificial membrane, which means that membrane-bound proteins can retain their natural structure and function.

New technology promises tests for diseases such as cancer in 15 minutes

Scientists at Leeds University in the UK say soon, testing for diseases such as cancer and multiple sclerosis, could take as little as 15 minutes and could be as simple as using a pregnancy testing kit.

Living sensor can warn of arsenic pollution

Scientists studying arsenic pollution have discovered a living sensor that can spot contamination. They have also discovered new bacteria that can clean up arsenic spills even in previously untreatable cold areas, microbiologists heard today (Monday 8 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.

Dividing cells find their middle by following a protein contour map

Self-organization keeps schools of fish, flocks of birds and colonies of termites in sync. It's also, according to new research, the way cells regulate the final stage of cell division. Scientists at Rockefeller University have shown that a protein-chemistry-based contour map, which helps individual proteins locate the center of their cell without direction from a 'master organizer,' is key to ensuring accurate division during mitosis.

Portable DNA sensors

A researcher at the National University at San Diego has taken a mathematical approach to a biological problem - how to design a portable DNA detector.

New super technology to detect food-borne pathogens, toxins

Researchers have developed a new technology that can simultaneously screen thousands of samples of food or water for several dangerous food-borne pathogens in one to two hours.

Directed self-ordering of organic molecules for electronics

A simple surface treatment technique demonstrated by a collaboration between researchers at the National Institute of Standards and Technology (NIST), Penn State and the University of Kentucky potentially offers a low-cost way to mass produce large arrays of organic electronic transistors on polymer sheets for a wide range of applications including flexible displays, "intelligent paper" and flexible sheets of biosensor arrays for field diagnostics.

Attenuation of NASH by stimulation of free fatty acid metabolism

Medically-complicated obesity is a societal problem that needs to be solved. Liver disease, specifically non-alcoholic steatohepatitis or NASH, is just one of the many complications of increased body weight.

New biosensor detects avian influenza in just minutes

Quick identification of avian influenza infection in poultry is critical to controlling outbreaks, but current detection methods can require several days to produce results.

27 Sep 2007

Fluorescence resonance energy transfer technology shows how cancer may take hold

A team, led by researchers at the Carnegie Institution,* has found a key biochemical cycle that suppresses the immune response, thereby allowing cancer cells to multiply unabated.
