In a video statement, NASA Administrator Jim Bridenstine announced that the agency has again delayed its complex James Webb telescope mission, this time to March 2021. The decision was reached after an assessment from an independent review board. The group also increased the estimated cost of the mission to $9.66 billion, a figure that exceeds the current cap of $8.7 billion set by Congress.

Work Begins to Boost LHC Luminosity
The Large Hadron Collider (LHC) at CERN officially entered a new stage with a groundbreaking ceremony to mark the start of the civil-engineering work for its High-Luminosity LHC (HL-LHC) upgrade. By 2026, this major project will considerably improve the performance of the LHC, increasing the number of collisions in the large experiments and boosting the probability for discovering new physics phenomena.
NOvA Reports Strong Evidence for Antineutrino Oscillation
For more than three years, scientists on the NOvA collaboration have observed neutrino particles as they oscillate from one type to another over a distance of 500 miles. Now, in a new result unveiled at the Neutrino 2018 conference in Heidelberg, Germany, the collaboration announced its first results using antineutrinos, presenting strong evidence of muon antineutrinos oscillating into electron antineutrinos over long distances, a phenomenon that has never been unambiguously observed.
NASA Developing Foam and Cork Insulation to Protect Deep Space Rocket
NASA is advancing state-of-the-art technology for thermal protection with more environmentally friendly materials and 3D printed molds for smaller parts. The agency says that extreme temperatures—ranging from -423°F to more than 200°F—call for novel thermal protection systems on the Space Launch System (SLS), its new heavy-lift rocket.
Spectroscopy Lab Finds New Property in Quantum Matter
A Johns Hopkins research team has proved that a particular quantum material can demonstrate electrical dipole fluctuations at conditions near -450°F, a theorized but never-before detected property involving irregular oscillations of tiny charged poles on the material.
Applied Superconductivity Center Names New Director
The reins of the Applied Superconductivity Center (ASC), hosted at the National High Magnetic Field Laboratory (CSA CSM), have been handed over to scientist and professor Lance Cooley, a CSA board director. Cooley takes over for his longtime mentor David Larbalestier, who will remain the chief scientist for materials at the MagLab and a professor at the FAMU-FSU College of Engineering.
X-ray Tech Reveals Lost 19th Century Images
A team of scientists led by Western University in London, Ontario, Canada, has revealed how art curators can use light to recover images preserved on otherwise damaged daguerreotype silver plates.
Cold Testing Underway on ITER’s Toroidal Field Coils
Engineers from SIMIC S.p.a., a contractor based in Italy, have wrapped up the first round of cold testing the toroidal field coils manufactured for ITER, a process that involved submitting the coil winding pack to a thermal cycle between room temperature and 80 K.
New Superconducting Cable Surfaces from Research Supporting US Navy
A research team from Florida State University’s Center for Advanced Power Systems and the Colorado-based Advanced Conductor Technologies LLC has demonstrated the first high-temperature superconducting direct current power transmission cable using ACT’s Conductor on Round Core (CORC) cable technology. The cables enable transmission of vast amounts of power at high currents that could be used to fuel power grids or help operate an all-electric ship for the US Navy, according to the team.
A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle is a rudimentary form of … Continue reading Dewar
Stirling Power Generator Recovers Both Cold Energy and Waste Heat
Plans for recovering LNG cold energy have become an important focus in the LNG industry and show great potential for increasing energy efficiency and reducing carbon emission.
Companies Adapt Cryocooler Technology for New Applications
Cryocoolers are making inroads into commercial applications and are getting closer to our everyday lives. It is well known in the cryogenics community that cryocoolers have been in increasing demand for wider applications.
Researchers Hunting Exoplanets with Superconducting Arrays
The key to revealing the exoplanets tucked away around the universe may just be locked up in the advancement of Microwave Kinetic Inductance Detectors (MKIDs), an array of superconducting detectors made from platinum sillicide and housed in a cryostat at 100 mK.
Cryocoolers, a Brief Overview
Cryocoolers are a type of refrigerator designed to reach cryogenic temperatures. Engineers use the term most often for smaller systems, typically no larger than table-top size, with input powers less than about 20 kW.
2nd International Conference on Cryogenics and Refrigeration Technologies
The city of Bucharest hosted the 2nd International Congress on Cryogenics and Refrigeration Technologies May 7-10, welcoming attendees with delicious food, pleasant parks, numerous museums and plenty of research and conversation.
