Endangered frogs coexist with fungus once thought fatal
Worldwide amphibian declines have reached crisis proportions. In many areas, habitat loss is the likely culprit but, in 1996, it was suggested that some unknown disease had spread through the populations. In 1998, the fungus Batrachochytrium dendrobatidis was identified from sick and dead ...UCLA scientists discover new way to fix defective gene
...ell's protein-reading machinery that a protein has reached full length and completed copying. In the mutated genes of A-T patients, PTCs halt the copying of proteins too early, resulting in shortened and unstable ATM proteins.

... proliferation of tumours. The scientists have reached these conclusions from results, obtained using microarrays, that compare the expression of 6,000 genes in breast cancer tumours in animals fed with n-6 fat-rich diets and in animals with low-fat diets. The tumours in the rats with the fat-rich diets ...International human genome sequencing consortium describes finished human genome sequence
