A record-setting x-ray microscopy experiment may have ushered in a new era for nanoscale imaging. Working at Lawrence Berkeley National Laboratory (Berkeley Lab), a collaboration of researchers used low energy or “soft” x-rays to image structures only 5 nm in size. This resolution, obtained at Berkeley Lab’s Advanced Light Source, is the highest ever achieved with x-ray microscopy.
When a segment of a major fault line goes quiet, it can mean one of two things: The “seismic gap” may simply be inactive, or the segment may be a source of potential earthquakes, quietly building tension over decades until an inevitable seismic release. Researchers from Massachusetts Institute of Technology and Turkey have found evidence for both types of behavior on different segments of the North Anatolian Fault.
During the six-day IMTS manufacturing technology show in Chicago this week, the “Strati” will be the first vehicle printed in one piece using direct digital manufacturing. The process will take more than 44 hours of print time. A team including Local Motors, Cincinnati Inc. and Oak Ridge National Laboratory will then rapidly assemble it for a historic first set for Saturday.
Biologists claim that humans can perceive and distinguish a trillion different odors, but little is known about the underlying chemical processes involved. Biochemists at The City College of New York have found an unexpected chemical strategy employed by the mammalian nose to detect chemicals known as aldehydes.
Optical circuits use light instead of electricity, making them faster and more energy-efficient than electrical systems. Scientists in Switzerland have now developed a silicon-based photonic crystal nanocavity to be used as a first building-block for photonic “transistors”. The new device requires record low energy to operate.
Researchers have been trying to increase the efficiency of solid oxide fuel cells by lowering the temperatures at which they run. In a serendipitous finding at Pacific Northwest National Laboratory, researchers have created a new form of strontium-chromium oxide that performs as a semiconductor and also allows oxygen to diffuse easily, a requirement for a solid oxide fuel cell.
A team of researchers has discovered a way to cool electrons to -228 C without external means and at room temperature, an advancement that could enable electronic devices to function with very little energy. The process involves passing electrons through a quantum well to cool them and keep them from heating.
For detecting cancer, manual breast exams seem low-tech compared to other methods such as MRI. But scientists are now developing an “electronic skin” that “feels” and images small lumps that fingers can miss. Knowing the size and shape of a lump could allow for earlier identification of breast cancer, which could save lives.
Despite being outlawed in 2012 in the U.S., the synthetic drugs known as “bath salts”—which really aren’t meant for your daily bath—are still readily available in some retail shops, on the Internet and on the streets. To help law enforcement, scientists are developing a novel method that could be the basis for the first portable, on-site testing device for identifying the drugs.
Some people avoid risks at all costs, while others will put their wealth, health and safety at risk without a thought. Researchers at Yale School of Medicine have found that the volume of the parietal cortex in the brain could predict where people fall on the risk-taking spectrum.
Objects in space tend to spin—and spin in a way that’s totally different from the way they spin on earth. Understanding how objects are spinning, where their centers of mass are, and how their mass is distributed is crucial to any number of actual or potential space missions, from cleaning up debris in the geosynchronous orbit favored by communications satellites to landing a demolition crew on a comet.
A high-tech survey reveals that there is more to Stonehenge than meets the eye, finding previously unknown monuments. Researchers have produced digital maps of what's beneath the World Heritage Site, using ground-penetrating radar, high-resolution magnetometers and other techniques to peer deep into the soil. And they have found some surprises.
The Hiden HPR-60 research mass spectrometer is conceived specifically for direct measurement of plasma. The plasma is sampled from atmospheric pressure through orifices separating three sequential stages of high pumping-speed pressure reduction, forming the extracted sample into a molecular beam for undisturbed high-integrity transfer of the reactive gas-phase species through to the integrated mass spectrometer.
Leica Microsystems and Med X Change announced that select Leica surgical microscopes are now available with integrated 1080p video recording and still image capture. The compact Med X Change EvolutionHD 2-D medical video recorder, EVO for short, integrates with the microscope stands, providing high-definition video recording without interrupting surgical workflow.
Apple is betting that people want to pay with a tap of the phone rather than a swipe of the card. The technology company on Tuesday introduced a new digital wallet service called Apple Pay that is integrated with its Passbook credential-storage app and its fingerprint ID security system. The announcement came as Apple introduced several new products including a new, larger iPhone 6 and a watch.
