New imaging technology promises better breast cancer detection in early stages

Scientists at the Research & Education Institute at Harbor-UCLA Medical Center (REI) are developing a new breast imaging diagnostic tool which will afford clinicians greater opportunities for detecting early stage breast cancers with greater certainty and help patients avoid biopsy in some cases. This detection method identifies breast lesions utilizing a radiopharmaceutical diagnostic imaging technology known as Tc-99 Sestamibi (MIBI) scintimammography. The procedure is based on a radioactive isotop

NHGRI launches genome.gov

The National Human Genome Research Institute (NHGRI) launched a totally redesigned Web site today with a new Internet address – genome.gov . The streamlined Web site address makes it easy for users to access a comprehensive and authoritative government site focused on genomic research, including the international Human Genome Project slated for completion in April 2003. The new Web site supports ongoing scientific studies by researchers inside and outside

Clemson researchers create biosensors to protect nation’s food and water supplies

Unlike nuclear terrorism, bioterrorism won’t begin with a bang. It will begin with a whimper — a child feeling the effects of food poisoning.

E.coli, Listeria, Campylobacter, Salmonella are not weapons of mass destruction, they are weapons of mass disruption. Experts say it’s not a matter of if but when terrorists will attempt a strike at our food or water supply. If they succeed, hundreds, perhaps thousands, of Americans will become sick, and some among the youngest and ol

Insight into how the body tells time

You may feel different at the dreary hour of 4 a.m. than you do mid-afternoon at 4 p.m. Now, researchers might understand why. A study from Washington University School of Medicine in St. Louis helps explain how genes dictate our biological clock.

Nearly all living things have a natural rhythm that influences their behavior and physiology. This rhythm typically is “circadian”, following a near 24-hour cycle. Driven by an internal clock, a creature’s natural rhythm is synchronized to th

Commission to double pharmaceutical research spending but more needs to be done

“I would like Europe to become a centre of excellence and a focus for pharmaceutical research once again”, stated EU Research Commissioner Philippe Busquin today at the annual assembly of the European pharmaceutical industry (EFPIA) in Bruges. “We need to nurture our research-based industries by reinforcing science and technology in Europe. Europe needs to invest more and in a better, more consistent way: it has to cut red tape and be bold.” From 1999 to 2002 the Commission invested around € 1 billio

100,000 More Plants Than Previously Thought – endangered?

A new study reveals a far greater diversity of plants on earth than previously estimated. Writing in the latest Plant Talk magazine (published on 12 June), leading botanist and conservationist Dr David Bramwell calculates that there are around 422,000 species of flowering plants (termed Angiosperms) in the world. Until now, most scientists had worked from a much lower figure of some 270,000 or 320,000 species.

The increased estimate shows that there is an even more urgent need to complete t
