An international team of researchers led by clinicians at Weill Cornell Medical College have discovered a genetic Achilles' heel in an aggressive type of prostate cancer -- a vulnerability they say can be attacked by a targeted drug that is already in clinical trials to treat other types of cancers.

Vultures in South Asia were on the brink of extinction until Lindsay Oaks and Richard Watson, from The Peregrine Fund in the US, undertook observational and forensic studies to find out why the number of birds was falling so rapidly. They discovered the vultures were being poisoned by residues of an anti-inflammatory drug (diclofenac) used in cattle and other livestock, whose carcasses they feed on. The work is presented in a chapter of the new book, 'Wildlife Ecotoxicology - Forensic Approaches,' published by Springer.

The lowly and simple roundworm may be the ideal laboratory model to learn more about the complex processes involved in repairing wounds and could eventually allow scientists to improve the body's response to healing skin wounds, a serious problem in diabetics and the elderly.

Biotechnology

The removal of rare tumor cells circulating in the blood might be possible with the use of biomolecules bound to dendrimers, highly branched synthetic polymers, which could efficiently sift and capture the diseased cells, according to new research at the University of Illinois at Chicago.
