Nanoparticles in cosmetics may be harmful to the environment

Using aquatic microbes as their "canary-in-a-cage," scientists from Ohio have reported that nanoparticles now being added to cosmetics, sunscreens, and hundreds of other personal care products may be harmful to the environment.

Polymer nanowires detect cancer biomarker

Investigators at the University of California, Riverside, have developed a simple and cost-effective method of building conducting polymer nanowires that can detect a wide range of levels of a cancer biomarker. This work, which was published in the journal Analytical Chemistry, could serve as a model for portable cancer detection equipment suitable for use in a doctor's office.

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.

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.
