Filming life in the fast lane

The new microscope, called Multi-View SPIM, or MuVi-SPIM for short, enables scientists to image rapid biological processes in thick samples at unprecedented detail. It builds upon the Selective-Plane Illumination Microscopy (SPIM) technology developed at EMBL a few years ago. Like SPIM, the new microscope shines a thin sheet of light on the embryo, illuminating one layer of a sample like this embryo at a time, to obtain an image of the whole sample with minimal light-induced damage. But MuVi-SPIM takes four full images from different angles, eliminating the need to rotate the sample.

US and European energy supplies vulnerable to climate change - Nature Climate Change

Higher water temperatures and reduced river flows in Europe and the United States in recent years have resulted in reduced production, or temporary shutdown, of several thermoelectric power plants, resulting in increased electricity prices and raising concerns about future energy security in a changing climate.

Thermoelectric (nuclear or fossil-fuelled) power plants, supply 91% and 78% of total electricity in the US and Europe respectively, thus disruption to their operation is a significant concern for the energy sector.

Nuclear and coal-fired electrical plants vulnerable to climate change

Warmer water and reduced river flows in the United States and Europe in recent years have led to reduced production, or temporary shutdown, of several thermoelectric power plants. For instance, the Browns Ferry Nuclear Plant in Alabama had to shut down more than once last summer because the Tennessee River's water was too warm to use it for cooling.

Altitude training: Study puts some data behind conventional wisdom

SAN FRANCISCO -- Altitude training is a popular technique among athletes preparing for a competition, especially expert runners. Much research has been conducted on how to do it, at what altitude to train, how to modify workouts and how long to stay at altitude. However, a major unanswered question is when should an athlete return from altitude to compete?

Coaches of elite runners generally take one of two sides.

American teens are less likely than European teens to use cigarettes and alcohol

ANN ARBOR, Mich.—The U.S. had the second-lowest proportion of students who used tobacco and alcohol compared to their counterparts in 36 European countries, a new report indicates.

The results originate from coordinated school surveys about substance use from more than 100,000 students in some of the largest countries in Europe like Germany, France and Italy, as well as many smaller ones from both Eastern and Western Europe.

UH students develop prototype device that translates sign language

Too often, communication barriers exist between those who can hear and those who cannot. Sign language has helped bridge such gaps, but many people are still not fluent in its motions and hand shapes.

Sandia National Laboratories' unique approach to materials allows temperature-stable circuits

ALBUQUERQUE, N.M — Sandia National Laboratories researcher Steve Dai jokes that his approach to creating materials whose properties won't degenerate during temperature swings is a lot like cooking — mixing ingredients and fusing them together in an oven.

Quantum computers will be able to simulate particle collisions

Quantum computers are still years away, but a trio of theorists has already figured out at least one talent they may have. According to the theorists, including one from the National Institute of Standards and Technology (NIST), physicists might one day use quantum computers to study the inner workings of the universe in ways that are far beyond the reach of even the most powerful conventional supercomputers.

Integrated sensors handle extreme conditions

A team of Case Western Reserve University engineers has designed and fabricated integrated amplifier circuits that operate under extreme temperatures – up to 600 degrees Celsius - a feat that was previously impossible.

The silicon carbide amplifiers have applications in both aerospace and energy industries. The devices can take the heat of collecting data inside of nuclear reactors and rocket engines, for example.

New small solid oxide fuel cell reaches record efficiency

RICHLAND, Wash. -- Individual homes and entire neighborhoods could be powered with a new, small-scale solid oxide fuel cell system that achieves up to 57 percent efficiency, significantly higher than the 30 to 50 percent efficiencies previously reported for other solid oxide fuel cell systems of its size, according to a study published in this month's issue of Journal of Power Sources.

Meeting biofuel production targets could change agricultural landscape

WASHINGTON, May 31, 2012 — The latest episode in the American Chemical Society's (ACS') award-winning Global Challenges/Chemistry Solutions podcast series explains that meeting current biofuel production targets with existing technology would require devoting almost 80 percent of current farmland in the U.S.

Wildfire and an example of its important link to the ecosystem

Thursday, May 31, 2012 - Traveling the western U.S. state of Nevada in the 1860s, a young American writer named Mark Twain heard a "world of talk" about the beauty of Lake Tahoe and so set out one August day to see the lake perched high in the Sierra Nevada Mountains. Determined to make the 11-mile journey on foot, Twain and his companions became briefly discouraged after toiling up one mountain and then another to no avail. But they trudged on until "at last the Lake burst upon us," Twain wrote in his 1872 book, Roughing It.

Nanotechnology breakthrough could dramatically improve medical tests

A laboratory test used to detect disease and perform biological research could be made more than 3 million times more sensitive, according to researchers who combined standard biological tools with a breakthrough in nanotechnology.

The increased performance could greatly improve the early detection of cancer, Alzheimer's disease and other disorders by allowing doctors to detect far lower concentrations of telltale markers than was previously practical.

A new tool to attack the mysteries of high-temperature superconductivity

Superconductivity, in which electric current flows without resistance, promises huge energy savings – from low-voltage electric grids with no transmission losses, superefficient motors and generators, and myriad other schemes. But such everyday applications still lie in the future, because conventional superconductivity in metals can't do the job.

Novel X-ray technique opens door to new biological insights

Scientists have used a novel X-ray technique to peer into the internal structure of a common biomolecule. The study, published in the journal Science, demonstrates the immense potential of new tools called free-electron lasers to obtain high-resolution structural insight into macromolecules.
