Combining diamond anvils and powerful lasers, laboratory researchers have developed a technique that should be able to squeeze materials to pressures 100 to 1,000 times greater than possible today, reproducing conditions expected in the cores of supergiant planets.
Until now, these pressures have only been available experimentally next to underground nuclear explosions.
Engineers at Washington University in St. Louis have developed a unique photocatlytic cell that splits water to produce hydrogen and oxygen in water using sunlight and the power of a nanostructured catalyst.
Researchers at Arizona State University's Polytechnic campus and the Military Amputee Research Program at Walter Reed Army Medical Center are teaming up to create the next generation of powered prosthetic devices based on lightweight energy storing springs.
The device, nicknamed SPARKy, short for Spring Ankle with Regenerative Kinetics, will be a first-of-its-kind smart, active and energy-storing transtibial (below-the-knee) prosthesis.
One of the most serious and least understood threats to the world's ecosystems is the problem of invasive species-exotic plants, animals and other organisms that are brought into habitats and subsequently spread at a rapid rate, often replacing native species and reducing biodiversity.
A team of biologists at Yale University and the University of Sheffield discovered anatomical details about the female reproductive tract in waterfowl that indicate that male and female anatomy have co-evolved in a "sexual arms race."
Researchers at The University of Warwick and Leicester University have used an artificial snot (nasal mucus) to significantly enhance the performance of electronic noses.
The researchers have coated the sensors used by odour sensing "electronic noses" with a mix of polymers that mimics the action of the mucus in the natural nose. This greatly improves the performance of the electronic devices allowing them to pick out a more diverse range of smells.
Life for an estimated 100,000 people in poverty-stricken rural India has been improved dramatically by several hours of reliable solar-powered lighting every night, made available by a UN-led pilot project to facilitate household financing for solar home systems.
The $1.5 million pilot, managed by the United Nations Environment Programme (UNEP), has improved so many lives in India that sister programmes to boost energy access are being initiated in other developing countries.
“The climate problem can by and large be solved if the eight to ten largest countries in the world can agree on effective climate measures,” says Professor Jon Hovi.
One of the themes at a recent climate conference arranged by the research program RENERGI was how we can achieve an effective international climate agreement. Professor in political science Jon Hovi at the University of Oslo and CICERO has studied this topic for years. He argues that although the international community faces many obstacles in mitigating the climate problem, solutions are possible.
Many studies in coaching literature have found that male athletes tend to prefer a male coach. Newly released research from the University of Alberta has indicated that male athletes actually prefer a female team physician to attend to their medical issues, including those related to sexual health.
Engineers at Washington University in St. Louis have developed a unique photocatlytic cell that splits water to produce hydrogen and oxygen in water using sunlight and the power of a nanostructured catalyst.
The discovery provides a new low cost and efficient option for hydrogen production and can be used for a variety of distributed energy applications.
Just because someone decides not to participate in a research project doesn't necessarily mean that they fundamentally object to taking part, a study published online in BMC Health Services Research suggests. Misunderstandings about the nature and process of a study often contribute to expressions of non-consent, a factor that should be incorporated in the design of future studies.
If you’ve ever wondered about the ultimate fate of the universe, Lawrence Krauss and Robert Scherrer have some good news - sort of. In a paper published online on April 25 in the journal Physical Review D, the two physicists show that matter as we know it will remain as the universe expands at an ever-increasing clip. That is, the current status quo between matter and its alter ego, radiation, will continue as the newly discovered force of dark energy pushes the universe apart.
Think you can come up with the best playlist for astronauts in the International Space Station? ESA wants to hear from you.
Everyone has a list of favorite tunes but what if you were suddenly transported 400 km above the Earth? What music would you take with you for entertainment as you floated around the world 16 times a day?
A wide variety of public policies affect alcohol purchases, consumption, and traffic fatalities, The two alcohol-control policies that have been most-clearly demonstrated to reduce youth consumption and traffic deaths are raising the minimum legal drinking age (MLDA) and raising beer taxes. Researchers have evaluated the independent effectiveness of these and many other policies. A new study finds that the effectiveness of any particular policy depends on what other policies are also in place.
The culture of a school can dampen – or exacerbate – the violent or disruptive tendencies of aggressive young teens, new research indicates. A large-scale study from the University of Illinois found that while personal traits and peer interactions have the most direct effect on the aggressive behavior of middle school students, the school environment also influences student aggression.
The study assessed individual, family and school predictors of aggression in 111,662 middle school students. The findings appear in the March 2007 issue of the journal, Youth & Society.
