By Ken Strandberg The European X-ray Free-electron Laser (European XFEL), recently completed its first experiments that captured images of an antibiotic-disabling enzyme. Scientists use X-rays to bombard molecules and project molecular smatterings on a sensor that reconstructs what the target looks like.  With these high-energy X-rays we now have 3D visualizations of actual molecules, like…

Thermo Fisher Scientific announces the launch of a next-generation, compressor-free plate sealer, designed to alleviate the maintenance burden on operators, while offering unparalleled process customization capabilities, intuitive operation and significant work efficiencies. Biotechnology, pharmaceutical, and academic research laboratories can now benefit from a system capable of simplifying the plate sealing process and enabling improved reliability…

In 2016, the Containerized Bio-Containment System (CBCS), developed by Kansas City-based MRIGlobal — with support from HHI Corp., GPA Services L.L.C., the U.S. State Department, and The Paul G. Allen Ebola Program — was named one of the R&D 100 winners. The system is a first-of-its-kind, flyable medical transport unit and features full biocontainment. It…

  Computer chips use billions of tiny switches, called transistors, to process information. The more transistors on a chip, the faster the computer. A material shaped like a one-dimensional DNA helix might further push the limits on a transistor’s size. The material comes from a rare earth element called tellurium. Researchers found that the material,…

The U.S. Department of Energy’s Oak Ridge National Laboratory and the Tennessee Valley Authority have signed a memorandum of understanding to evaluate a new generation of flexible, cost-effective advanced nuclear reactors. Under the agreement, ORNL and TVA will collaborate on ways to improve the economic feasibility of potentially licensing, building, operating and maintaining one or…

Photothermal therapy (PTT)–a proposed treatment for diseases such as antibacterial-resistant infections and cancer–makes use of a chemical agent that absorbs the light of an infrared laser and dissipates that energy as local heat capable of killing cells, including cancer cells. But most of the chemical agents used for PTT are toxic to human cells and…

You don’t need a big laser to make laser-induced graphene (LIG). Scientists at Rice University, the University of Tennessee, Knoxville (UT Knoxville) and Oak Ridge National Laboratory (ORNL) are using a very small visible beam to burn the foamy form of carbon into microscopic patterns. The labs of Rice chemist James Tour, which discovered the…

When there are several processes going on at once, establishing cause-and-effect relationships is difficult. This scenario holds true for a class of high-temperature superconductors known as the cuprates. Discovered nearly 35 years ago,  these copper-oxygen compounds can conduct electricity without resistance under certain conditions. They must be chemically modified (“doped”) with additional atoms that introduce…

The National Aeronautic Association announced today that work being done by the Texas A&M University-Corpus Christi Lone Star UAS Center of Excellence & Innovation and NASA is among nine aviation and space achievements that will compete for the 2019 Robert J. Collier Trophy for excellence in aeronautics and astronautics in America. “We were flattered when…
