Scientists using a variant of atomic force microscopy called Kelvin probe force microscopy, at low temperatures and in ultrahigh vacuum, have recently obtained the first image of the charge distribution within a single molecule. The molecule is the same as the type used in IBM’s single-molecule logic switch.
Researchers at Massachusetts Institute of Technology have developed a new approach to MEMS design that enables engineers to design 3D configurations, using existing fabrication processes; with this approach, the researchers built a MEMS device that enables 3D sensing on a single chip. The tiny device contain microscopic elements that can be engineered to reach heights of hundreds of microns above the chip's surface.
Scientists in Switzerland and Germany have recently accomplished with quantum sources a task similar in spirit to those pioneered in the 19th century by Heinrich Hertz and Guglielmo Marconi: They have achieved the excitation of a single molecule with a single photon. Researchers accomplished this elusive task by inventing a single-photon source that is able to match frequencies with the molecules in question.
Intended to help cut red tape for business and startups wanting to do business with the U.S. Dept. of Energy’s research laboratories, the new Agreements for Commercializing Technology (ACT) program was recently launched as a third alternative to the two preceding options: signing a Cooperative Research and Development Agreement (CRADA) or a Work For Others (WFO) Agreement.
Flu bugs are common in humans, birds and pigs and have even been seen in dogs, horses, seals and whales, among others. But for the first time, scientists have found evidence of flu in bats, reporting a never-before-seen virus whose risk to humans is unclear.
Researchers at Oak Ridge National Laboratory are sharing computational resources and expertise to improve the detail and performance of the Community Earth System Model, a scientific application code that is the product of one of the world's largest collaborations of climate researchers.
Earlier this month, the president's budget canceled joint U.S.-European robotic missions to Mars in 2016 and 2018. Now top science officials say they are scrambling to come up with a plan by the end of the summer for a cut-rate journey to the red planet in 2018. That's when Mars passes closest to Earth, something that only happens once every 15 years.
A long-standing controversy regarding the semiconductor gallium manganese arsenide, one of the most promising materials for spintronic technology, looks to have been resolved. Researchers with Lawrence Berkeley National Laboratory and Notre Dame University found the that the spintronic properties do not arise from a valence energy band, as many scientists have argued.
For the past decade, scientists have been developing cancer treatments based on RNA interference, which shuts off malfunctioning genes with short snippets of DNA. Delivering the RNA, however, has been a problem. The solution at Paula Hammond’s Massachusetts Institute of Technology laboratory is to pack the RNA into microspheres so dense they reach their destination intact.
A new collaboration between Brookhaven National Laboratory and Best Medical International (BMI) aims to design one of the most dynamic and effective cancer therapy devices in the world. The ion Rapidly Cycling Medical Synchrotron (iRCMS) draws on the particle acceleration expertise of Brookhaven Laboratory physicists and the medical experience of BMI to advance cancer therapy, particularly the evolving use of carbon and other light ions.
Researchers have developed a wireless link that bridges two fiber-optic points at an unprecedented 20 billion bits of data per second. The phenomenal speed, which is to be presented at the Optical Fiber Communication Conference and Exposition in Los Angeles next week, was achieved using much higher frequencies than have been typically used in mobile communications.
Ten milliliters of blood may not seem like a lot, and coming from healthy individuals it isn't. But for critically ill patients with diminished resources, 10 mL could be crucial. Nonetheless, that's what's currently required to test for circulating tumor cells in late-stage cancer. However, a Northeastern team of engineers has developed an alternative testing method.
The size of Sifrhippus , the earliest known horse, correlates surprisingly well with average global temperatures, according to a recent study. The discoveries about its changes in stature, fluctuating from 12 to 8.5 to 15 lbs, offer new evidence of the cause and effect relationship between temperature and body size. The findings also offer clues to what might happen to animals in the near future.
A multinational team of scientists has developed a process for creating glass-based, inorganic light-emitting diodes (LEDs) that produce light in the ultraviolet range. If successfully integrated into biomedical devices, these would be the first robust, cheap to produce, and chemically stable LEDs to operate in the medically-useful UV spectrum.
Physicists at the Georgia Institute of Technology have added another measurement to the list of those that can be squeezed. In a recent paper, they report squeezing a property called the nematic tensor, which is used to describe the rubidium atoms in Bose-Einstein condensates, a unique form of matter in which all atoms have the same quantum state.
