South Asia Disaster Shows Tsunamis Are An Ongoing Threat To Humans
The tsunami that devastated south Asia coastlines and killed more than 200,000 people last December is a powerful reminder of just how dangerous those waves can be to humans, and scientists should use the event to help people prepare for the next one, a University of Washington scientist says. Cheap And Easy Technique To Produce Hydrogen From Visible Light Is Alm
There is a revolution in solar hydrogen on the horizon. The prospect for the wide spread use of hydrogen as a portable energy carrier is dependent on finding a clean, renewable method of production. A research group headed by a professor of electrical engineering is "only a couple of problems away"from developing an inexpensive and easily scalable technique for water photoelectrolysis - the splitting of water into hydrogen and oxygen using light energy -- that could help power the proposed hydrogen economy. New Options In 'Personalized'Cancer Treatment And Prevention
Molecular diagnostics promises to provide new strategies for tailoring therapies to fit the needs of each cancer patient's unique biology. Researchers can now fine-tuned the treatment of a number of different cancer types, including lung and ovarian, based on the genetic profile of the patient's tumors. UCLA-VA Study Names India Dietary Staple As Potential Alzheimer's Weap
A dietary staple of India, where Alzheimer's disease rates are reportedly among the world's lowest, holds potential as a weapon in the fight against the disease. The new UCLA-Veterans Affairs study involving genetically altered mice suggests that curcumin, the yellow pigment in curry spice, inhibits the accumulation of destructive beta amyloids in the brains of Alzheimer's patients and also breaks up existing plaques. Volcanic Structures Monitored In The Andes Via Satellite Show Unexpect
The high elevation of the Andes Cordillera make surveillance of these volcanic structures complicated and restricting. Researchers recently investigated a volcanic complex located on the Argentina-Chile border using images captured by a European Space Agency satellite. The data acquired showed that over the study area two types of deformation appear to affect the terrestrial crust. Hepatitis C Helicase Unwinds DNA In A Spring-loaded, Three-step Proces
The process by which genes are duplicated is mysterious and complex, involving a cast of characters with diverse talents and the ability to play well with others in extremely close quarters. A key player on this stage is an enzyme called a helicase. Its job is to unwind DNA or RNA so that another enzyme, a polymerase, can faithfully copy each nucleotide in the genetic code. A study to appear in Science sheds new light on how the hepatitis C helicase plays this role. Parasites A Key To The Decline Of Red Colobus Monkeys In Forest Fragme
Forest fragmentation threatens biodiversity, often causing declines or local extinctions in a majority of species while enhancing the prospects of a few. A new study shows that parasites can play a pivotal role in the decline of species in fragmented forests. This is the first study to look at how forest fragmentation increases the burden of infectious parasites on animals already stressed by disturbances to their habitat. Species Detectives Track Unseen Evolution
New species are evading detection using a foolproof disguise -- their own unchanged appearance. Research suggests that the phenomenon of different animal species not being visually distinct despite other significant genetic differences is widespread in the animal kingdom. DNA profiles and distinct mating groups are the only way to spot an evolutionary splinter group from their look-alike cousins, introducing uncertainty to biodiversity estimates globally. Scientists Learning To Create Nanomaterials Based On Micro-algae Patte
Researchers at the Georgia Institute of Technology have developed a technique to study how unicellular micro-algae, known as diatoms, create their complex cell walls. Researchers hope to learn how diatoms assemble these nanometer-patterned, intricate micro-architectures to find better methods for creating nanomaterials in the laboratory. In Search of Myths &Heroes
Companion website to a Public Broadcasting Service (PBS) program that "goes in search of four of the world's most famous myths": the Queen of Sheba, Shangri-La, King Arthur, and Jason and the Argonauts. Features general information about myths, essays on the specific myths discussed in the program, information about the archetypes ("universal symbolic patterns") found in the stories, video clips, and lesson plans.
