The search for life beyond Earth is one of the grandest endeavors in the history of humankind, a quest that could transform our understanding of our universe both scientifically and spiritually. With news coming this week that NASA has confirmed the presence of flowing saltwater on the surface of Mars, the hunt for life on the Red Planet has new momentum.
Researchers from North Carolina State Univ., NIST and UNSW Australia have measured the behavior of specific atoms in dielectric materials when exposed to an electric field. The work advances our understanding of dielectric materials, which are used in a wide variety of applications.
You may want to opt for a different coffee-carrying receptacle. According to the Environmental Protection Agency, Americans discard 25 billion Styrofoam coffee cups per year. What’s more, the coffee cup used today will still be present in a landfill 500 years from now. However, the solution to ridding the environment of these persisting materials may lie in a creepy-crawly.
Ironwood Electronics has introduced a new LCC socket design using high-performance elastomer capable of 75 GHz, very low inductance and wide temperature applications. The GT-QFN-3010 socket is designed for 14.3x14.3 mm package size and operates at bandwidths up to 75 GHz with less than 1dB of insertion loss.
Earth’s magnetic field is vital for life. It deflects solar wind and protects the planet’s atmosphere, according to European Space Agency. The field is generated in Earth’s core and emanates outwards. Using computer simulations to replicate planets in the habitable zones of low-mass stars, Univ. of Washington researchers found tidally locked Earth-like planets may possess protective magnetic fields.
Scientists have recorded measurements of x-rays of energies up to 10 MeV caused by electrons accelerated in the intense electric fields inside a thundercloud. The researchers were able to mount equipment on an Airbus during test flights that took place in April 2014.
In an effort to help develop a sustainable domestic supply of rare earth elements and lessen the U.S.'s dependence on China for materials that are vital to the production of electronics, wind turbines and many other technologies, two researchers at Worcester Polytechnic Institute have developed a method of extracting rare earths from the drive units and motors of discarded electric and hybrid cars.
Caused by the bacterium Yersinia pestis, the plague caused some major pandemics in human history. The Justinian Plague, which started in 541 and persisted for 200 years, wiped out over 25 million people. It was followed by the “Black Death,” which originated in China in 1334 and spread via trade routes to Constantinople and Europe.
Scientists have been exploring new ways to “smell” signs of cancer by analyzing what’s in patients’ breath. In Nano Letters, one team now reports new progress toward this goal. The researchers have developed a small array of flexible sensors, which accurately detect compounds in breath samples that are specific to ovarian cancer.
In the television drama “Mission Impossible,” instructions for the mission were delivered on an audio tape that destroyed itself immediately after being played. Should that series ever be revived, its producers might want to talk with Georgia Institute of Technology professor Andrei Fedorov about using his “disappearing circuits” to deliver the instructions.
HEMCO Corp.'s Universal is perfect for laboratories where space is limited or when multiple hoods are needed. Universal fume hoods are offered in 24-, 30-, 35- and 47-in widths. Hoods are designed for light to medium duty fume removal, and features sturdy dual wall construction and a fully vertical sliding sash. Dual walls reduce sound and vibration.
When European Space Agency astronaut Samantha Cristoforetti, NASA’s Terry Virts and Roscosmos commander Anton Shkaplerov returned to Earth following an extended period in space, helping hands greeted them upon exiting the landing module. Members of the ground crew carried the space travelers to a sitting area nearby the landing site.
Purdue Univ. has created a new lyophilization consortium, LyoHUB, to improve freeze-drying technology to make food, pharmaceuticals and biotech products safer and more affordable. The center is funded by NIST through a $453,623 planning grant from its Advanced Manufacturing Technology Consortia, or AMTech, program.
The Prior Scientific HLD117 series of linear stages for inverted research microscopes set new standards for convenience and top performance. The HLD117 linear stages operate on a different principle from conventional stepper motor, ball screw based motorized stages.
Researchers at Rice Univ. and Baylor College of Medicine have unlocked the structural details of a protein seen as key to treating a neuromuscular disease. Their success at obtaining a structural map of a protein known as leiomodin 2 (Lmod2) attached to two actin subunits offers a path forward for the study of nemaline myopathy, a hereditary disorder that weakens the muscles and can sometimes be fatal.
