Scientists must offer solutions for conserving tropical forests in a rapidly changing world
As human populations and their impacts on the world increase, tropical forests are changing in many different ways. Forests are being cleared, burned, logged, fragmented, and overhunted and an unprecedented pace. view more (2005-09-06)
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)
Tulane researcher reports on origin of deadly fever outbreak
Bats or other cave dwelling animals may have been responsible for the deadly 1998-2000 outbreak of Marburg hemorrhagic fever among gold miners in the Democratic Republic of the Congo. view more (2006-09-14)
Tropical forests — Earth's air conditioner
Planting and protecting trees—which trap and absorb carbon dioxide as they grow—can help to remove carbon dioxide from the atmosphere. view more (2007-04-10)
NASA satellite sees Olaf stretch out and fizzle over northwestern mainland Mexico
Tropical Storm Olaf wasn't given much of a chance when he was born, and he never did make it to hurricane strength before fizzling out late Saturday night. view more (2009-10-06)
The cost of long tongues
Orchid bees use their extraordinarily long tongues to drink nectar from the deep, tropical flowers only they can access. view more (2007-04-17)
Tropical rainforest nutrients linked to global carbon dioxide levels
Extra amounts of key nutrients in tropical rain forest soils cause them to release more carbon dioxide into the atmosphere, according to research conducted by scientists at the University of Colorado (CU)—Boulder. view more (2006-06-21)
The drivers of tropical deforestation are changing, say scientists
A shift from poverty-driven to industry-driven deforestation threatens the world's tropical forests but offers new opportunities for conservation, according to an article coauthored by William Laurance of the Smithsonian Tropical Research Institute in Panama. view more (2008-08-06)
Link between tropical warming and greenhouse gases stronger than ever, say scientists
New evidence from climate records of the past provides some of the strongest indications yet of a direct link between tropical warmth and higher greenhouse gas levels, say scientists at the University of California, Santa Barbara. view more (2005-10-14)
Looming tropical disaster needs urgent action
A major review by University of Adelaide researchers shows that the world is losing the battle over tropical habitat loss with potentially disastrous implications for biodiversity and human well-being. view more (2008-06-25)
Brazil demonstrating that reducing tropical deforestation is key win-win global warming solution
Tropical deforestation is the source of nearly a fifth of annual, human-induced emissions of heat-trapping gases to the atmosphere. view more (2007-05-16)
New method for measuring biodiversity
German and Sri Lankan researchers have developed a new method for measuring the impacts of species on local biodiversity. It makes it possible to determine whether a certain species promotes or suppresses species diversity. view more (2008-02-19)
Study finds multiple neglected tropical diseases effectively treated with drugs
The neglected tropical diseases are a group of 13 infectious diseases, including elephantiasis, hookworm, African sleeping sickness and trachoma, which affect more than 1 billion people worldwide, most of whom live in extreme poverty. view more (2007-10-26)
Satellite survey links tropical park fires with poverty and corruption
According to the first global assessment of forest fire control effectiveness in tropical parks, poverty and corruption correlate closely with lack of fire protection in tropical moist forests. view more (2007-07-10)
A change in the wind
Climate model simulations for the 21st century indicate a robust increase in wind shear in the tropical Atlantic due to global warming, which may inhibit hurricane development and intensification. view more (2007-04-18)
Insect warning colors aid cancer and tropical disease drug discovery
Brightly colored beetles or butterfly larvae nibbling on a plant may signal the presence of chemical compounds active against cancer cell lines and tropical parasitic diseases, according to researchers at Smithsonian's Tropical Research Institute in Panama. view more (2008-07-09)
Nitrogen pollution boosts plant growth in tropics by 20 percent
A study by UC Irvine ecologists finds that excess nitrogen in tropical forests boosts plant growth by an average of 20 percent, countering the belief that such forests would not respond to nitrogen pollution. view more (2008-02-07)
Scientists use lasers to measure changes to tropical forests
New technology deployed on airplanes is helping scientists quantify landscape-scale changes occurring to Big Island tropical forests from non-native plants and other environmental factors that affect carbon sequestration. view more (2009-01-26)
Survey shows disgust emotion evolved to safeguard humans from disease and secure adaptive advantage
The emotion of disgust evolved to protect humans from the risk of infectious disease and ensure our adaptive advantage, according to a survey of over 40,000 people published today in the Royal Society's 'Biology Letters'. Our reactions to things which make us go 'yuck', such as bodily fluids, lesions and faeces has long been the source of... view more... (2004-01-14)
Scientists may have solved an ecological riddle
A team of scientists may have solved the riddle of why plants that work with bacteria to convert atmospheric nitrogen gas into an essential biological nutrient (ammonia) tend to prevail in the world's tropical regions rather than higher latitudes. view more (2008-06-19)
