Bugs Reveal the Richness of Species On Earth An international team of researchers has carried out a survey of the biological diversity in a tropical rainforest. Their efforts have helped them find the key to one of the existential questions to which people have long sought an answer: how many species exist on Earth? "After nearly ten years of work, we have determined that Panama's San Lorenzo forest is home to 25,000 arthropods. This is the

Lower Nitrogen Losses With Perennial Biofuel Crops Perennial biofuel crops such as miscanthus, whose high yields have led them to be considered an eventual alternative to corn in producing ethanol, are now shown to have another beneficial characteristic -- the ability to reduce the escape of nitrogen in the environment. In a 4-year University of Illinois study that compared miscanthus, switchgrass, and mixed prairie species to typical corn-corn-so

Giant Tobacco Plants That Stay Young Forever Tobacco plants bloom when they are just a few months old -- and then they die. Now, researchers have located a genetic switch which can keep the plants young for years and which permits unbounded growth. In short, an ideal source of biomass. The life of tobacco plants is short. They grow for around three to four months, followed by flowering and then die. Their size is also limited, with plants on

Birdsong Study Pecks Theory That Music Is Uniquely Human A bird listening to birdsong may experience some of the same emotions as a human listening to music, suggests a new study on white-throated sparrows, published in Frontiers of Evolutionary Neuroscience. "We found that the same neural reward system is activated in female birds in the breeding state that are listening to male birdsong, and in people listening to music that they like," says Sarah Ear

Two New Species of Orchid Found in Cuba Researchers from the University of Vigo, in collaboration with the Environmental Services Unit at the Alejandro de Humboldt National Park (Cuba), have discovered two new species of Caribbean orchid. The Caribbean islands have been natural laboratories and a source of inspiration for biologists for over two centuries now. Suffice to say that the studies by Charles Darwin and Alfred Russel Wallace i

Fluctuating Environment May Have Driven Human Evolution A series of rapid environmental changes in East Africa roughly 2 million years ago may be responsible for driving human evolution, according to researchers at Penn State and Rutgers University. "The landscape early humans were inhabiting transitioned rapidly back and forth between a closed woodland and an open grassland about five to six times during a period of 200,000 years," said Clayton Magill

Discovery of Africa Moth Species Important for Agriculture, Controlling Invasive Plants In the rain forests of the Congo, where mammals and birds are hunted to near-extinction, an impenetrable sound of buzzing insects blankets the atmosphere. Because it is a fairly inaccessible region with political unrest, much of the Congo's insect biodiversity remains largely undiscovered. In a new monographic book published this week in Zootaxa, researchers at the University of Florida and the

Do Palm Trees Hold the Key to Immortality? For centuries, humans have been exploring, researching, and, in some cases, discovering how to stave off life-threatening diseases, increase life spans, and obtain immortality. Biologists, doctors, spiritual gurus, and even explorers have pursued these quests -- one of the most well-known examples being the legendary search by Ponce de León for the "Fountain of Youth." Yet the key to longevity may
