Benefits of improved access to day care cancelled out by low pay trap
Mothers from socially disadvantaged families with access to good day care are more likely to take up paid work, but could actually see a reduction in their household income as a result, according to research published in today's British Medical Journal. The study was the first randomised controlled trial of the effects of day care to be conducted... view more... (2003-10-16)

Unsafe injections rejected as major source of HIV infection in Africa (p 482)
A recent theory proposing that unsafe injections are a major cause of HIV-1 infection in sub-Saharan Africa is rejected by authors of an article in this week's issue of THE LANCET. During the past year, a group (D Gisselquist and colleagues) has argued that unsafe injections are a major mode of HIV-1 transmission in sub-Saharan Africa, with up to... view more... (2004-02-04)
Coralline algae in the Mediterranean lost their tropical element between 5 and 7 million years ago

Fossil teeth of browsing horse found in Panama Canal earthworks
Rushing to salvage fossils from the Panama Canal earthworks, Aldo Rincon, paleontology intern at the Smithsonian Tropical Research Institute, unearthed a set of fossil teeth. Bruce J. MacFadden, curator of vertebrate paleontology at the Florida Museum of Natural History, University of Florida in Gainesville, describes the fossil as Anchitherium... view more... (2009-06-09)
Princeton-led team finds secret ingredient for the health of tropical rainforests
A team of researchers led by Princeton University scientists has found for the first time that tropical rainforests, a vital part of the Earth's ecosystem, rely on the rare trace element molybdenum to capture the nitrogen fertilizer needed to support their wildly productive growth. view more (2008-12-10)
Finding Genetic Gold In The Amazon
Brazilian scientists may have found a new source for plastics and life saving medicines by cracking the genetic code of Chromobacterium violaceum, a free-living bacterium that commonly floats along the Rio Negro river in the Amazon rainforest. The complete genome sequence, which will be published in a future issue of the Proceedings of the... view more... (2003-09-12)
Almost 7 million pregnant in sub-Saharan Africa infected with hookworms; at risk of anaemia
