A robotic arm that can bend, stretch and squeeze through cluttered environments has been created by a group of researchers from Italy. Inspired by the eight arms of an octopus, the device has been specifically designed for surgical operations to enable surgeons to easily access remote, confined regions of the body and, once there, manipulate soft organs without damaging them.
The latest version of a microfluidic device for capturing rare circulating tumor cells is the...
Modern medicine relies on optical fibers to cauterize unhealthy veins in a minimally invasive...
The world’s first reference material to help ensure laboratories accurately “map” DNA for genetic testing, medical diagnoses and future customized drug therapies is now available from NIST. The new reference material, NIST RM 8398, is a “measuring stick” for the human genome, the coded blueprints of a person’s genetic traits.
It looks like a Slinky suspended in motion. Yet this photonics advancement, called a metamaterial hyperlens, doesn’t climb down stairs. Instead, it improves our ability to see tiny objects. The hyperlens may someday help detect some of the most lethal forms of cancer.
Univ. of California, Berkeley researchers have developed algorithms that enable robots to learn motor tasks through trial and error using a process that more closely approximates the way humans learn, marking a major milestone in the field of artificial intelligence. They demonstrated their technique, a type of reinforcement learning, by having a robot complete various tasks without pre-programmed details about its surroundings.
Omega Engineering’s new series of CE-compliant ultrasonic leak detectors features an ultrasonic sound range of 20 to 100 kHz. The HHLT-1 series is suitable for pressure and vacuum system leak detection, exhaust system, tanks and pipe leak testing, as well as steam trap inspection and gas leaks in general.
Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner.
Data centers are one of the largest and fastest-growing consumers of electricity in the U.S. The industry has been shifting from open-air cooling of these facilities to increasingly complex systems that segregate hot air from cold air. When it comes to cost savings, there are definite advantages to the aisle containment systems, which have been estimated to save 30% of cooling energy.
The efficiency of synchrotron light sources is heavily dependent on the vacuum quality within the beam lines, small mass spectrometers (RGAs) are routinely utilized to provide real-time vacuum monitoring for confirmation of contaminant status, and the associated radiation level is a potential issue. Hiden Analytical manufactures quadrupole mass spectrometers with radiation hardened electronics having operation established at radiation levels in the regime of 1x10E7 Rads per annum.
A Univ. of Wyoming faculty member led a research team that discovered a certain type of soil bacteria can use their social behavior of outer membrane exchange (OME) to repair damaged cells and improve the fitness of the bacteria population as a whole.
Scientists, for the first time, have precisely measured a protein’s natural “knee-jerk” reaction to the breaking of a chemical bond—a quaking motion that propagated through the protein at the speed of sound. The result, from an x-ray laser experiment at the SLAC National Accelerator Laboratory, could provide clues to how more complex processes unfold as chemical bonds form and break.
NASA’s Mars Curiosity Rover’s ChemCam instrument just got a major capability fix, as Los Alamos National Laboratory scientists uploaded a software repair for the auto-focus system on the instrument. The team realized last November that a small laser used to focus the ChemCam telescope on its target fialed. And without this laser rangefinder, the instrument was blind.
When it comes to magnets, a doctor’s trash is a physicist’s treasure. Researchers at Argonne National Laboratory recently acquired two decommissioned magnets from magnetic resonance imaging (MRI) scanners from hospitals in Minnesota and California that will find a new home as proving grounds for instruments used in high-energy and nuclear physics experiments.
Purdue Univ. research shows that a small amount of nicotinoid pesticide substantially weakens termites' ability to fight off fungal diseases, a finding that could lead to more effective methods of pest control. The study also provides clues into termites' robust defense systems and how nicotinoids affect social insects.
Massachusetts Institute of Technology researchers have shown that they can use a microfluidic cell-squeezing device to introduce specific antigens inside the immune system’s B cells, providing a new approach to developing and implementing antigen-presenting cell vaccines.
An automated software system developed at Los Alamos National Laboratory played a key role in the discovery of supernova iPTF 14atg and could provide insight, a virtual Rosetta stone, into future supernovae and their underlying physics.
Chemists at The Scripps Research Institute have discovered a broad and strikingly inexpensive method for synthesizing “amines,” a class of organic compounds prominent in drugs and other modern products. The new reaction is particularly useful for synthesizing complex amines that would be highly valuable in pharmaceuticals, but are impractical—or impossible—to make with standard methods.
