Embryonic development is already disturbed at concentrations 10 times lower than the norm for human consumption.

Dioxin-like contaminants such as PCB’s are probably playing a key role in the extinction of the eel. Embronyic development in this species is halted at dioxin concentrations 10 times below the levels for human consumption. This discovery was made by a team of biologists, led by Guido van den Thillart, who are conducting research in Leiden into the sexual maturity and

Oil palm is the most widely produced and consumed vegetable oil in developing countries. With around 3.3 tonnes per hectare per year, it is 7 or 8 times more productive than soybean oil. Palm and soybean are the most widely consumed oils worldwide. Indonesia and Malaysia are the world’s leading palm oil producers, with 12 and 14 million tonnes of oil per year respectively. However, a soil fungus, Ganoderma boninense, which causes basal stem rot in oil palms, devastates thousands of hectares

The vast differences between humans and chimpanzees are due more to changes in gene regulation than differences in individual genes themselves, researchers from Yale, the University of Chicago, and the Hall Institute in Parkville, Victoria, Australia, argue in the 9 March 2006 issue of the journal Nature.

The scientists provide powerful new evidence for a 30-year-old theory, proposed in a classic paper from Mary-Claire King and Allan Wilson of Berkeley. That 1975 paper documented

Alzheimer’s disease–specific biomarkers clearly are needed for the differential diagnosis of cognitive impairment in the elderly. What sets age-related disorders like hypertension, hypercholesterolemia and diabetes mellitus apart from Alzheimer’s disease is that each has biomarkers that can be followed easily and repeatedly, not simply to diagnose, but also to monitor response and optimize treatment. In contrast, the current role of clinical labor

The record-breaking performance of the Tevatron collider at the Department of Energy’s Fermi National Accelerator Laboratory is pushing the search for dark matter, supersymmetric particles and extra dimensions to new limits. Repeatedly smashing peak luminosity records, the Tevatron has created record numbers of proton-antiproton collisions that provide the means to unveil the secrets of the universe. Accelerator experts at the lab announced today (March 2) that in only 14 months the Tevatron

The thyroid gland is very sensitive to ionizing radiation. The number of patients with thyroid gland cancer is particularly high among those who endured the Chernobyl catastrophe in childhood. Ultrasonic scanning and bioptic tests investigations are usually used for early detection of thyroid gland cancer but researchers do not stop the search of more efficient methods.

They deal with molecular markers of cancer in order to discover mutation of the genes participating in carcinogenesis.
