Giant bacteria found in Guadeloupe mangroves challenge traditional concepts
Peer-Reviewed Publication
Researchers at the DOE Joint Genome Institute, Lawrence Berkeley National Laboratory (Berkeley Lab), the Laboratory for Research in Complex Systems (LRC) and at the Université des Antilles describe the morphological and genomic features of a “’macro’ microbe” – a giant filamentous bacterium composed of a single cell discovered in the mangroves of Guadeloupe. Using various microscopy techniques, the team also observed novel, membrane-bound compartments that contain DNA clusters dubbed “pepins.”
Scientists at Berkeley Lab and UC Berkeley have developed a thin film from a century-old material for next-gen memory and logic devices. The breakthrough advances the pursuit of low-voltage electronics that require less energy to operate than today’s silicon-based electronics.
Today, U.S. Secretary of Energy Jennifer Granholm announced ten U.S. scientists and engineers as recipients of the prestigious Ernest Orlando Lawrence Award for their exceptional contributions in research and development supporting the Energy Department’s missions in science, energy, and national security. Established in 1959, the Lawrence Award recognizes mid-career U.S. scientists and engineers who have advanced new research and scientific discovery in nine categories representing the broad science and engineering missions of DOE and its programs. The awards are among the longest running and most prestigious science and technology awards bestowed by the U.S. Government.
American farms produce food, animal feed and biofuel for the world. Scientists from Argonne National Laboratory are providing valuable tools to help big agriculture make decisions that maximize potential but cancel out greenhouse gas emissions.
New scientific results confirm an anomaly seen in previous experiments, which may point to an as-yet-unconfirmed new elementary particle, the sterile neutrino, or indicate the need for a new interpretation of an aspect of standard model physics, such as the neutrino cross section, first measured 60 years ago. Los Alamos National Laboratory is the lead American institution collaborating on the Baksan Experiment on Sterile Transitions (BEST) experiment, results of which were recently published in the journals Physical Review Letters and Physical Review C.
After a long day of work, you might feel tired or exhilarated. Either way, you are affected by what happened to you in the past. Accelerator magnets are no different. What they went through – or what went through them, like an electric current – affects how they will perform in the future. Without understanding a magnet’s past, researchers might need to fully reset them before starting a new experiment, a process that can take 10 or 15 minutes. Some accelerators have hundreds of magnets, and the process can quickly become time-consuming and costly.
For would-be quantum programmers scratching their heads over how to jump into the game as quantum computers proliferate and become publicly accessible, a new beginner’s guide provides a thorough introduction to quantum algorithms and their implementation on existing hardware.
Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed an upcycling approach that adds value to discarded plastics for reuse in additive manufacturing, or 3D printing. The readily adoptable, scalable method introduces a closed-loop strategy that could globally reduce plastic waste and cut carbon emissions tied to plastic production.
