It’s beginning to look like SpaceX will attempt to make the 15 km (9.3 mi) hop test before Christmas! After two successful 150 m (~500 ft) hops with the SN5 and SN6 prototypes, engineers at SpaceX’s Boca Chica launch facility in South Texas rolled out the SN8 – the first Starship prototype to have three Raptor engines. […]

Super Heavyweight and Flyweight in a Cosmic Dance Volunteer distributed computing project Einstein@Home discovers neutron star in unusual binary system. After more than two decades, an international research team led by the Max Planck Institute for Gravitational Physics (Albert Einstein Institute; AEI) in Hannover has identified a Galactic “mystery source” of gamma rays: a […]

Measurements from the Copernicus Sentinel-5P satellite show that this year’s ozone hole over the Antarctic is one of the largest in recent years. A detailed analyses from the German Aerospace Center indicates that the hole has now reached its maximum size. Credit: ESA Measurements from the Copernicus Sentinel-5P satellite show […]

TU Graz researcher Stefan Spirk has found a way to replace liquid electrolytes in redox flow batteries with vanillin. Credit: © Lunghammer – TU Graz Researchers at TU Graz have found a way to convert the aromatic substance vanillin into a redox-active electrolyte material for liquid batteries. The technology is […]

The Milky Way Galaxy is seen in this illustration. Credit: NASA/JPL-Caltech/R. Hurt (SSC/Caltech) A halo is a large region filled with hot gas that surrounds a galaxy, also known as a “circumgalactic medium.” The heated gaseous halo around the Milky Way was the incubator for the Milky Way’s formation some 13 billion […]

Progeny of novel combination is more vigorous and productive than parental plants. Novel grafted plants — consisting of rootstock epigenetically modified to “believe” it has been under stress — joined to an unmodified scion, or above-ground shoot, give rise to progeny that are more vigorous, productive, and resilient than the […]

Composite image showing Jupiter’s moon Io in radio (ALMA), and optical light (Voyager 1 and Galileo). The ALMA images of Io show for the first time plumes of sulfur dioxide (in yellow) rise up from its volcanoes. Jupiter is visible in the background (Hubble).

Complex interlocking components mean no tools are needed. Credit: © Larsson et al. An interactive system to design and fabricate structurally sound wood joints. Wood is considered an attractive construction material for both aesthetic and environmental purposes. Construction of useful wood objects requires complicated structures and ways to connect components […]
