Hurricane frequency is up but not their strength, say Clemson researchers
In a new study, Clemson University researchers have concluded that the number of hurricanes and tropical storms in the Atlantic Basin is increasing, but there is no evidence that their individual strengths are any greater than storms of the past or that the chances of a U.S. strike are up. view more (2009-09-23)
Researchers link Ice Age climate-change records to ocean salinity
Sudden decreases 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. view more (2006-10-05)
Scientists: As rainfall changes, tropical plants may acclimate
Tropical plants may be more adaptable than commonly thought to changing rainfall patterns expected to accompany a warming climate, new research shows. view more (2007-05-08)
The Influence Of Disturbance On Tropical Rain Forest Biodiversity : End Of A Controversy In Sight
The many species which make up tropical rain forest tree communities show widely differing reactions to environmental factors. This is particularly so with regard to light. Pioneer species, highly heliophile (light-loving or shade-intolerant), establish themselves by taking advantage of canopy light gaps opened up by treefalls. Rapid growth, a... view more...

New Ballast Treatment Could Help Shield Lake Superior from Deadly Fish Disease
A Michigan Technological University professor has developed a new water treatment that could help keep a deadly fish disease out of Lake Superior. view more (2008-06-05)
Los Alamos Scientists See New Mechanism for Superconductivity
Laboratory researchers have posited an explanation for superconductivity that may open the door to the discovery of new, unconventional forms of superconductivity. view more (2008-11-24)
Urban green spaces lengthen pensioners' lives
The availability of nearby parks and tree-lined streets in large, densely populated cities significantly increases the longevity of pensioners, finds a study in the Journal of Epidemiology and Community Health. From 1992 onwards, the researchers monitored the longevity of over 3,000 people born in 1903, 1908, 1913, and 1918. All the study... view more... (2002-11-22)
Free smoke alarms to poor local authority households are a waste of time and money
Local authority schemes aimed at reducing fire-related injuries and deaths in poor urban households by providing and installing free smoke alarms could be a waste of time and money, according to a study carried out by researchers from the London School of Hygiene & Tropical Medicine. The study, the findings of which are published in today's... view more... (2002-10-31)
Smithsonian scientists discover new marine species in eastern Pacific
Smithsonian scientists have discovered a biodiversity bounty in the Eastern Pacific—approximately 50 percent of the organisms found in some groups are new to science. The research team spent 11 days in the Eastern Pacific, a unique, understudied region off the coast of Panama. view more (2007-03-09)
Caribbean corals decline 80% in 25 years
Coral reefs across the Caribbean have suffered a phenomenal 80% decline in their coral cover during the past three decades, reveals new research from the University of East Anglia (UEA) and the Tyndall Centre for Climate Change Research, published this week in the international online journal Science Express. The amount of reef covered by hard... view more... (2003-07-17)
Monocolonialism holds clues for understanding the little fire ant
The presence of Wasmannia auropunctata in New Caledonia was first recorded in 1972. This small ant, with workers measuring only 1 or 2 mm, originates from tropical America. It was introduced by human activity, accidentally brought in, probably on plant material imported for use in forestry. The ant has colonized almost every ecological type of... view more...

Food security for leaf-cutting ants: Workers and their fungus garden reject endophyte invaders
New diseases directly affect human survival and food security, especially as population density climbs. Leaf-cutting ants, one of a few groups of social insects to cultivate crops, have harvested plant material to fertilize their underground fungal gardens for ~50 million years. view more (2009-04-03)
Researchers discover trees in Amazon much older than assumed, raising questions on global climate impact of region
Trees in the Amazon tropical forests are old. Really old, in fact, which comes as a surprise to a team of American and Brazilian researchers studying tree growth in the world's largest tropical region. view more (2005-12-14)
Community spread of trachoma could be stopped by treating all household members
All members of the household need to be treated for trachoma in order to prevent rapid re-infection, according to a new study published in PLoS Neglected Tropical Diseases. view more (2009-03-31)

Panama butterfly migrations linked to El Niño, climate change
A high-speed chase across the Panama Canal in a Boston Whaler may sound like the beginning of another James Bond film-but the protagonist of this story brandishes a butterfly net and studies the effects of climate change on insect migrations at the Smithsonian Tropical Research Institute. view more (2009-10-06)
Tropical forest seed banks: a blast from the past
Seeds of some tree species in the Panamanian tropical forest can survive for more than 30 years before germinating. view more (2009-04-02)
NASA scientists report on new technology to help protect US troops from infectious diseases
Representatives from NASA convened in New Orleans today to report at the American Society of Tropical Medicine and Hygiene Annual Meeting the results from a NASA-enhanced computerized system to assess environmental and health concerns for deployed U.S. forces. view more (2008-12-11)
NASA Researchers Studying Tropical Cyclones
NASA hurricane researchers are deploying to Costa Rica next month to investigate the birthplace of eastern Pacific tropical cyclones. They will be searching for clues that could lead to a greater understanding and better predictability of one of the world's most significant weather events - the hurricane. view more (2005-06-24)
