PROMISING RESULTS FOR MALARIA VACCINE (p 1927)
Results of a study from The Gambia in this week's issue of THE LANCET provide evidence of a vaccine that could prevent malaria caused by the micro-organism Plasmodium falciparum. P. falciparum malaria remains a major cause of disease and death in many parts of the tropics, especially in sub-Saharan Africa. The development of an effective vaccine... view more... (2001-12-05)

Merck investigational vaccine GARDASIL prevented 100 percent of cervical pre- & non-invasive cancers
Merck & Co., Inc., prevented 100 percent of high-grade cervical pre-cancers and non-invasive cervical cancers (CIN 2/3 and AIS) associated with human papillomavirus (HPV) types 16 and 18 in a new phase III study.   view more (2005-10-07)

Accelerated evolution converts RNA enzyme to DNA enzyme in vitro
This 'evolutionary conversion' provides a modern-day snapshot of how life as we understand it may have first evolved out of the earliest primordial mix of RNA-like molecules-sometimes referred to as the "pre-RNA world"-into a more complex form of RNA-based life (or the "RNA world") and eventually to cellular life based on DNA... view more...
