Killer bees may increase food supplies for native bees
Aggressive African bees were accidentally released in Brazil in 1957. As "killer bees" spread northward, David Roubik, staff scientist at the Smithsonian Tropical Research Institute, began a 17-year study that revealed that Africanized bees caused less damage to native bees than changes in the weather and may have increased the... view more...

Amazon powers tropical ocean's carbon sink
Nutrients from the Amazon River spread well beyond the continental shelf and drive carbon capture in the deep ocean, according to the authors of a multi-year study. view more (2008-07-22)
Tropical plants go with the flow ... of nitrogen
Tropical plants are able to adapt to environmental change by extracting nitrogen from a variety of sources, according to a new study that appears in the May 7 early online edition of The Proceedings of the National Academy of Sciences. view more (2007-05-08)
No convincing evidence for decline in tropical forests
Claims that tropical forests are declining cannot be backed up by hard evidence, according to new research from the University of Leeds. view more (2008-01-08)
How chilly was the last ice age?
Polar oceans permanently covered with ice, temperatures ten to twelve degrees Celsius lower than today in the North Atlantic region, tropical oceans on the other hand only two degrees Celsius below modern values: Until quite recently these were the general ideas climate researchers had about the climax of the last ice age 20.000 years ago. Now... view more... (1999-05-03)
Singing in the rainforest: Public vs. private signaling by a tropical rainforest bird
According to the Chinese proverb, a bird sings because it has a song, not because it has an answer. A team of French and Brazilian researchers, however, may have the answer as to how the song of Brazilian white-browed warbler has become so well-adapted to the acoustic properties of the rainforest environment. view more (2008-02-13)
Tuberculosis risk for travellers (pp 442, 461)
The risk of tuberculosis infection in long-term travellers to countries with high prevalence of the disease is substantial and of similar magnitude to the average risk for the local population, according to research published in this week’s issue of THE LANCET. Little attention has been paid to the potential of international travellers to... view more... (2000-08-02)
New Models of Weather Pattern
For a mathematician, Joseph Biello spends a lot of time thinking about the weather. But the UC Davis assistant professor isn't looking out the office window. He is using mathematical theory to build a model of the Madden-Julian Oscillation, a tropical weather pattern that influences drought and rainfall in the western U.S. view more (2005-12-12)
Ineffective monotherapies common in high-burden malarious countries
ACTwatch, a research project led by PSI, in collaboration with the London School of Hygiene and Tropical Medicine, released evidence today that indicates that artemisinin combination therapy, the most effective medicines for treating malaria, continue to have a significantly low presence on the market among populations considered to be most at... view more...

New study warns limited carbon market puts 20 percent of tropical forest at risk
In an ironic twist, 11 countries that have avoided widespread destruction of their tropical forest are at risk of being left out of an emerging carbon market intended to promote rainforest conservation to combat climate change. view more (2007-08-14)
Outflow from World's Largest River - the Amazon - Powers Atlantic Ocean Carbon
Nutrients from the Amazon River's outflow spread well beyond the continental shelf and drive carbon cycling in the tropical ocean, say scientists who conducted a multi-year study. They will publish their results this week online in the journal Proceedings of the National Academy of Sciences (PNAS). view more (2008-07-23)
ETH Project with Costa Rica Set up for Drug Discovery
Nature produces highly interesting substances, which for years have met with great scientific interest. Chance, such as is used for instance in combinatorial chemistry for the synthesis of compounds, cannot replace the intelligence of nature, especially not in terms of the structural diversity of substances. In tropical countries in particular,... view more... (2003-05-19)
NRL's P-3 aircraft support project to study tropical cyclones
The Naval Research Laboratory (NRL) has been hunting for tropical cyclones as part of a multi-national study to understand, observe, and predict the potential impacts of Pacific tropical cyclones. view more (2008-12-08)
Living In A Time Of Plague: The Population Biology Of Emerging And Re-emerging Pathogens - Philosophical Transactions Of The Royal Society Of London Series B Vol. 356, No. 1411. Cover Date: 29 July 2001
LIVING IN A TIME OF PLAGUE: THE POPULATION BIOLOGY OF EMERGING AND RE-EMERGING PATHOGENS "We are living in a time of plague: infectious diseases continue to exert a huge toll in human and animal lives and suffering," says Professor Mark Woolhouse. "New diseases continue to emerge and medicine and veterinary medicine are failing to keep up." New or... view more... (2001-07-15)
Climate change responsible for increased hurricanes
Human induced climate change, rather than naturally occurring ocean cycles, may be responsible for the recent increases in frequency and strength of North Atlantic hurricanes. view more (2006-05-31)
Eat oily fish at least once a week to protect your eyesight in old age
Eating oily fish once a week may reduce age-related macular degeneration (AMD) which is the major cause of blindness and poor vision in adults in western countries and the third cause of global blindness, according to a study published today in the American Journal of Clinical Nutrition. view more (2008-08-11)
Saving the peatlands of Borneo
Recent EU funding for University of Leicester research into Borneo peatlands will help to save the natural habitat of species such as the orang-utan, already under threat. The island of Borneo includes 11 million hectares of peatland, an area almost half the size of the land area of the UK, important reservoirs of biodiversity, which include rare... view more...

Extinction most likely for rare trees in the Amazon rainforest
Common tree species in the Amazon will survive even grim scenarios of deforestation and road-building, but rare trees could suffer extinction rates of up to 50 percent, predict Smithsonian scientists and colleagues in the Aug. 12 issue of the journal Proceedings of the National Academy of Science. view more (2008-08-14)
Old age not a barrier for dialysis treatment (p 1543)
Favourable survival rates and the prognosis of a good quality of life suggest that old age should not be a barrier to receiving dialysis treatment for kidney failure, concludes research published in this week’s issue of THE LANCET. Evidence-based health policy is needed to meet the increasing demand for health services among elderly people,... view more... (2000-11-01)
Malaria experts to unveil top-flight research during international conference at The University of Nottingham
Some of the world's leading authorities on tropical diseases and parasitic infections will gather for an international conference at The University of Nottingham to discuss the latest breakthroughs in research and treatments. view more (2005-02-03)
