After 20 Years of Trying, Scientists Succeed in Doping a 1D Atomic Chain of Cuprates
An illustration depicts an unexpectedly strong attraction between electrons in neighboring lattice sites within a 1D chain of copper oxide, or cuprate – a material that conducts electrical current with no loss at relatively high temperatures. A study led by Stanford, SLAC and Clemson discovered this unusually strong “nearest-neighbor” attraction in a 1D cuprate chain that had been “doped” to increase the density of its free electrons. They said the unexpected strength of the attractions may result from interactions with natural vibrations in the material’s atomic lattice, which may play a role in cuprate superconductivity.

Dramatic Video of Mars Helicopter’s Challenging Flight Captured by NASA’s Perseverance Rover
Lead Image: NASA Mars Helicopter Ingenuity illustration. Credit: NASA/JPL Recently downlinked imagery of a September flight has allowed the rover imaging team to put together a video of rotorcraft performing to near-perfection. Video footage from NASA’s Perseverance Mars rover of the Ingenuity Mars Helicopter’s 13th flight on September 4 provides the most detailed look yet of the rotorcraft in action. Ingenuity is currently prepping for its 16th flight, scheduled to take place no earlier than Saturday, November 20, but the 160.5-second Flight 13 stands out as one of Ingenuity’s most complicated. It involved flying into varied terrain within the “Séítah”…

NASA’s Webb Space Telescope Primed To Reveal Secrets of Galaxy’s Most Mysterious Planets
Illustration showing what exoplanet GJ 1214 b could look like based on current information. GJ 1214 b, a warm sub-Neptune-sized exoplanet roughly 48 light-years from Earth, is one of the most studied exoplanets in the galaxy. Previous spectroscopic observations indicate that the planet is shrouded in aerosols (clouds or haze), which have thus far made it impossible to determine the composition of gases that make up its thick atmosphere.

Player (STScI) NASA’s James Webb Space Telescope Primed to Lift the Haze Surrounding Sub-Neptunes Detailed atmospheric studies will provide key insights into some of the…

Scientists Go “Inside” the COVID-19 Viral Protein To Attack a Weak Point
Lead Image: Virtual reality technology enabled scientists to look “inside” the Covid-19 virus and develop a novel molecule that can inhibit its main protease enzyme. Credit: Jill Hemman/ORNL Virtual reality (VR) technology enables scientists to create 3-D models of an object and then virtually go “inside” to look around to better understand its structure and function. This is what researchers at the Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) did to study the SARS-CoV-2 virus that caused the COVID-19 pandemic. The team used neutrons and x-rays to map part of the internal structure of the coronavirus to create…

Market Forces Cut Methane Emissions From Uinta Basin Oil and Gas Wells in Half – But That’s Not the Whole Story
Lead Image: Map of the Uinta Basin in eastern Utah, methanols observational sites, and oil/gas wells. Observational sites include Horsepool (HPL), Castlepeak (CSP), and Fruitland (FRU). The grayscale is the atmospheric footprint of the HPL site as simulated by the HRRR-STILT transport model. Satellite imagery from Google Earth. Credit: University of Utah Longest continuously-monitored methane emissions record shows how market forces and oilfield practices can impact greenhouse gas emissions. As important as emissions of the greenhouse gas methane are in the climate conversation, recently factoring prominently in the recent COP26 conference in Glasgow, researchers have painfully little long-term data on…
