More frequent and more economically costly storms, floods, droughts and other extreme weather. Wetter conditions in northern Europe but drier weather in the south that could threaten agriculture in some areas. More frequent and more intense heatwaves, posing a lethal threat to the elderly and frail. Melting glaciers, with three-quarters of those in the Swiss Alps likely to disappear by 2050. Rising sea levels for centuries to come.
These are among the impacts of global climate
The University Twente (The Netherlands), representing a network of 12 partners, has received a considerable grant from the European Commission to implement the nanotechnology program ‘Frontiers’.
Frontiers is a European network which aims at establishing leadership in research and innovation on behalf of life sciences related nanotechnology by integrating the strengths and facilities of the network partners. This integrated approach will strengthen Europe’s position in nanosciences
NASA, Naval Research Laboratory (NRL) and Scripps Institution of Oceanography scientists have assembled in the Arabian Desert to study tiny airborne particles called aerosols and their effect on weather and climate. The scientists are collaborating with researchers from the United Arab Emirates Department of Water Resources Studies and 20 other U.S., European and South African research laboratories to decipher the complex processes controlling the area’s climate.

For most people, the need to wear eyeglasses to read is an inevitable part of aging. The eye’s natural lens hardens and loses its ability to change shape, making it more difficult to focus, especially when reading up close.
With age also comes the development of cataracts or clouding of the eye’s natural lens. Intraocular lenses (IOLs) traditionally have been used to replace the eye’s natural lens after its removal during cataract surgery. However, with the tradition
The wind transports pollen far less effectively than scientists assumed, according to a new study of invasive Atlantic cordgrass by researchers at UC Davis. This discovery will help control a cordgrass, Spartina alterniflora, that is invading wetlands on the Pacific coast.
Plants including grasses, oaks and pine trees need the wind to carry pollen between plants, fertilizing nascent seeds. Scientists guessed that wind pollination was efficient, but the theory hadn’t been tested.
Sophisticated tools used to survey and monitor passenger flows through busy metro stations may result in unmanageable data loads. ADVISOR’s decision support tools reduce the workload of operators and increase the utility of the data output.
ADVISOR, which stands for Annotated Digital Video for Intelligent Surveillance and Optimised Retrieval, “is a significant aid to the operators in charge of metro security,” says project coordinator Michael Naylor. “The principal of the [ADVISO
As her PhD defended at the Public University of Navarre, telecommunications engineer Ixone Arroabarren has analysed the vibrato, one of the most important tools of classical singers.
The study applies both to the teaching of singing in music as well as to the medical treatment of voice pathologies. It has put forward a mathematical model for the production of the voice that can be used both in the medical study/detection of pathologies of the vocal chords and speech as well as the

A new study from the Johns Hopkins Children’s Center and 12 other medical centers shows the most effective treatment for adolescents with major depressive disorder is a combination of antidepressants and psychotherapy. Researchers say the study’s findings indicate this combination treatment may be best for both improving depression and reducing the level of suicidal thinking in adolescents.

In 1991, an exotic bivalve called the zebra mussel moved into the Hudson River. Over the past two decades, the prolific species has colonized habitats with hard sediments, becoming the most abundant animal in the river’s freshwater reaches. As competitors in the aquatic food chain, scientists have long speculated that zebra mussels may impact fish. A recent Canadian Journal of Fisheries and Aquatic Sciences article, written by Dr. David L. Strayer of the Institute of Ecosystem Studies (IES) and
Since rain and freshwater flooding are the number one causes of death from hurricanes in the United States over the last 30 years, better understanding of these storms is vital for insuring public safety. A recent study funded by NASA and the National Science Foundation offers insight into patterns of rainfall from tropical storms and hurricanes around the world.

Teenagers suffering from depression improved more with a combination of an antidepressant and cognitive-behavior therapy than they did when treated with either separately, a multicenter study published today in the Journal of the American Medical Association shows.
Results of a national, yearlong government-funded study in which UT Southwestern Medical Center at Dallas researchers participated also showed that depressed teens treated only with cognitive-behavior therapy did little bet
New Model Can Aid In Understanding Immune System Diseases Researchers trying to understand diseases and develop new treatments can’t always depend on existing tools or organisms to make discoveries; sometimes they first must create models of the problems they want to study.
Such is the case with Epstein-Barr, a common virus that is often harmless but likely contributes to malignancies and autoimmnune disease in people with compromised immunity. A University of Iowa team has enginee
In this retrospective study, eighty-eight patients with advanced hepatocellular carcinoma (HCC) were treated with long-term chemotherapy infusion into the hepatic artery, the main artery that supplies the liver. Known as hepatic arterial chemotherapy, this treatment requires a reservoir/pump system to supply the drug directly to the liver and the liver cancer. The reservoir port systems currently available have to be surgically implanted, making this treatment unavailable to many patients who were u
Two new moons orbiting between Mimas and Enceladus, discovered by the NASA/ESA/ASI Cassini-Huygens spacecraft, may be the smallest bodies so far seen around the ringed planet.
The moons are approximately three kilometres and four kilometres across. Located 194 000 kilometres and 211 000 kilometres from the planet’s centre, the moons are between the orbits of two other Saturnian moons, Mimas and Enceladus. They are provisionally named S/2004 S1 and S/2004 S2, bringing the current
Penn State engineer has developed a new technology that uses light-activated glue to hold workpieces in position for machining, grinding and other manufacturing processes.
Dr. Edward De Meter, professor of industrial and manufacturing engineering, who developed the concept, says, “This new technology offers an alternative to mechanical clamping, the approach industries most often use. Capital investment for automated clamping is typically high and mechanical clamps can deform the w
