Engineers investigating NASA’s Voyager 1 telemetry data
While the Voyager 1 spacecraft continues to return science data and otherwise operate as normal, the mission team is searching for the source of a system data issue. The engineering team with NASA’s Voyager 1 spacecraft is trying to solve a mystery: The interstellar explorer is operating normally, receiving and executing commands from Earth, along […]
First direct observation of the dead-cone effect in particle physics
The ALICE collaboration at the Large Hadron Collider (LHC) has made the first direct observation of the dead-cone effect—a fundamental feature of the theory of the strong force that binds quarks and gluons together into protons, neutrons and, ultimately, all atomic nuclei. In addition to confirming this effect, the observation, reported in a paper published […]
Engineers show how tungsten oxide can be used as a catalyst in sustainable chemical conversions
Engineers rely on catalysts for a vast array of applications from food manufacturing to chemical production, so finding efficient, environmentally friendly catalysts is an important avenue of research. New research led by the University of Pittsburgh Swanson School of Engineering could lead to the creation of new, sustainable catalysts based on tungsten oxide and similar […]
Researchers magnify hidden biological structures by combining SRS and expansion microscopy
A research team from Carnegie Mellon University and Columbia have combined two emerging imaging technologies to better view a wide range of biomolecules, including proteins, lipids and DNA, at the nanoscale. Their technique, which brings together expansion microscopy and stimulated Raman scattering microscopy, is detailed in Advanced Science. Biomolecules are traditionally imaged using fluorescent microscopy, […]
Satellite monitoring of biodiversity moves within reach
Global biodiversity assessments require the collection of data on changes in plant biodiversity on an ongoing basis. Researchers from the universities of Zurich and Montréal have now shown that plant communities can be reliably monitored using imaging spectroscopy, which in the future will be possible via satellite. This paves the way for near real-time global […]
Puzzling features deep in Earth interior illuminated by high resolution imaging
New research led by the University of Cambridge is the first to take a detailed image of an unusual pocket of rock at the boundary layer with Earth’s core, some three thousand kilometers beneath the surface. The enigmatic area of rock, which is located almost directly beneath the Hawaiian Islands, is one of several ultra-low […]
