A bee's future as queen or worker may rest with parasitic fly
Strange things are happening in the lowland tropical forests of Panama and Costa Rica. A tiny parasitic fly is affecting the social behavior of a nocturnal bee, helping to determine which individuals become queens and which become workers. view more (2008-07-29)
Africa: International volunteer impact small, but significant

Tropical storm risk consortium announces forecast for US hurricane strikes in 2001
Atlantic hurricane activity and the numbers of hurricanes striking US shores between June and November 2001 are anticipated to be 20% above average, a team of UK scientists said today. Dr Mark Saunders, Dr Paul Rockett and Dr Tony Hamilton of the Benfield Greig Hazard Research Centre at University College London (UCL) have developed innovative... view more... (2000-12-04)
Tropical regions to be hardest hit by fisheries shifts caused by climate change: UBC research
Major shifts in fisheries distribution due to climate change will affect food security in tropical regions most adversely, according to a study led by the Sea Around Us Project at The University of British Columbia. view more (2009-10-08)
Titan's icy climate mimics Earth's tropics
If space travelers ever visit Saturn's largest moon, they will find a tropical world where temperatures plunge to minus 274 degrees Fahrenheit, methane rains from the sky and dunes of ice or tar cover the planet's most arid regions. These conditions reflect a cold mirror image of Earth's tropical climate. view more (2007-10-03)
Promising trials of malaria vaccine lead to calls for Phase 3 development
Experts are recommending that a malaria vaccine progress to Phase 3 trials following the successful trial of the RTS, S/AS01E malaria vaccine among 5-17 month old children in Korogwe, Tanzania and coastal Kenya, which is reported today in the New England Journal of Medicine (NEJM). view more (2008-12-09)
Where climate is made in a greenhouse world
New scientific results for the Late Cretaceous greenhouse indicate radically different climatic mechanisms operating about 75-90 million years ago compared to the ones that control today's climate. view more (2006-06-02)
Cutting-edge health care training in Africa
Oxford University researchers are developing a pilot `E-learning Certification Programme in Global Health` directed at health professionals working in Africa, following a donation of US $500,000 (£325,000) from the Bill & Melinda Gates Foundation. Increasing strains on the health care system in many African countries created by AIDS and... view more... (2002-10-25)
New fossil plant discovery links Patagonia to New Guinea in a warmer past
Fossil plants are windows to the past, providing us with clues as to what our planet looked like millions of years ago. view more (2009-11-11)
2007 hurricane forecasts took blow from winds and Saharan dry, dusty air
A new analysis of environmental conditions over the Atlantic Ocean shows that hot, dry air associated with dust outbreaks from the Sahara desert was a likely contributor to the quieter-than-expected 2007 hurricane season. view more (2008-08-19)
New findings show persistent El Ni√ħo-like conditions during past global warming
During the most recent period in Earth's past with a climate warmer than today, the tropical Pacific was in a stable state of El Ni√ħo-like conditions, according to a new study by researchers at the University of California, Santa Cruz. view more (2005-06-24)
Smithsonian study concludes Caribbean extinctions occurred 2M years after apparent cause
Smithsonian scientists and colleagues report a new study that may shake up the way paleontologists think about how environmental change shapes life on Earth. The researchers summarized the environmental, ecological and evolutionary consequences for Caribbean shallow-water marine communities when the Isthmus of Panama was formed. view more (2007-03-13)
Leicester researcher to lead global team tackling carbon 'time-bomb'
A leading environmental researcher at the University of Leicester is to head an international team to protect an area that stores up to 70 billion tonnes of carbon. view more (2007-03-09)
Solar cycle linked to global climate, drives events similar to El Nino, La Nina
Establishing a key link between the solar cycle and global climate, new research led by the National Center for Atmospheric Research (NCAR) shows that maximum solar activity and its aftermath have impacts on Earth that resemble La Nina and El Nino events in the tropical Pacific Ocean. view more (2009-07-17)
Solar cycle linked to global climate
Establishing a key link between the solar cycle and global climate, research led by scientists at the National Science Foundation (NSF)-funded National Center for Atmospheric Research (NCAR) in Boulder, Colo., shows that maximum solar activity and its aftermath have impacts on Earth that resemble La Niña and El Niño events in the... view more...

Satellites show Amazon parks, indigenous reserves stop forest clearing
In a paper recently published in Conservation Biology (2006, Vol 20, pages 65-73), an international team of scientists, led by Daniel Nepstad of the Woods Hole Research Center and the Instituto de Pesquisa Ambiental da Amazonia, use satellite data to demonstrate, for the first time, that rainforest parks and indigenous territories halt... view more...

Mode of seed dispersal greatly shapes placement of rainforest trees
The apple might not fall far from the tree, but new research shows that how it falls might be what is most important in determining tree distribution across a forest. This study of the seed dispersal methods of rainforest trees demonstrates that these methods play a primary role in the organization of plant species in tropical forests. view more (2006-11-29)
The first neotropical rainforest was home of the Titanoboa
Smithsonian researchers working in Colombia's Cerrejón coal mine have unearthed the first megafossil evidence of a neotropical rainforest. view more (2009-10-13)
Ice Age North Atlantic temperatures, tropical oceans linked
Sudden shifts in temperature over Greenland and tropical rainfall patterns during the last ice age have been linked for the first time to rapid changes in the salinity of the north Atlantic Ocean, according to research published Oct. 5 in the journal Nature. view more (2006-10-05)
