Copper selenide (Cu₂Se) attracts scientific interest for its thermoelectric ability to convert heat into electricity, but a lack of atomic-level understanding has limited its practical applications for decades.

The man, who was spotted carrying multiple pairs of jeans, injured himself while resisting; when he was taken to a hospital, he tried to flee again before being taken into custody
A research team led by geophysicists at UC San Diego’s Scripps Institution of Oceanography provides an explanation for features that characterize the surface of the solar system’s hottest planet.

The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed an unexpected difference between the powerful winds launching from a disk around a neutron star and those from material circling supermassive black holes.
Blue Origin is committed to making a permanent human presence in space a reality. To this end, they have developed the New Shepard and New Glenn rockets to send payloads to orbit, and aim to create super-heavy launch vehicles to reach the moon (New Armstrong and Blue Origin) and beyond. Another focus has been on developing systems that will enable In-Situ Resource Utilization (ISRU) in extraterrestrial environments, which is essential for making space sustainable. This includes their Blue Alchemist ISRU system, which recently completed its Critical Design Review (CDR).
A newly launched supply ship has run into engine trouble that is preventing it from reaching the International Space Station.
A rare glimpse into the wintry conditions of the Mars north polar vortex has shown that temperatures inside the vortex are far colder than outside, and that the permanent darkness that winter brings to the Martian north pole facilitates a surge in ozone in the atmosphere.
In a scientific breakthrough with cosmic implications, researchers have, for the first time, precisely dated the emergence of microbial life within a meteorite impact crater—revealing that life not only survives catastrophe, but thrives in its aftermath.
An international research collaboration has used advanced computer simulations to investigate how faint radio signals from the early universe, soon to be observed from missions on the far side of the moon, could shed light on the fundamental properties of dark matter.
Researchers have developed a new type of microscope that can acquire extremely large, high-resolution pictures of non-flat objects in a single snapshot. This innovation could speed up research and medical diagnostics or be useful in quality inspection applications.
Researchers from Japan have discovered a unique Hall effect resulting from deflection of electrons due to “in-plane magnetization” of ferromagnetic oxide films (SrRuO3). Arising from the spontaneous coupling of spin-orbit magnetization within SrRuO3 films, the effect overturns the century-old assumption that only out-of-plane magnetization can trigger the Hall effect.
A massive, mysterious Hole has just opened up on the surface of Antarctica leaving experts confused as they are unable to explain what caused its formation. The hole—as large as lake superior or the state of Maine, with an approximate area of 30,000 square mile—has created confusion among experts, who are unable to explain as to why exactly its there. Some blame it on climate change, but the truth is scientists have no idea. According to atmospheric physicist Kent Moore, a professor at the University of Toronto’s Mississauga campus in an interview with Motherboard: the gigantic, mysterious hole “is quite remarkable, it looks like you just punched a hole in the ice.” This is not the first time massive holes have appeared on Antarctica.  The mysterious apeparence—referrede to as a polynya—is off for a number of reasons but mostly because of its behavior. It was spotted for the first time in the 1970’s but disappeared for several decades before showing up again, causing confusion among scientists. “At that time, the scientific community had just launched the first satellites that provided images of the sea-ice cover from space,” Dr. Torge Martin of the GEOMAR Research Division explains of its initial discovery many decades ago. “On-site measurements in the Southern Ocean still require enormous efforts, so they are quite limited.” The massive hole was recently found by a group of researchers from the University of Toronto and the Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) project, as they were monitoring the area with satellite technology after a similar hole appeared on Antarctica last years.  The 2017 hole is the largest one ever detected, having a diameter of around 30,000 square miles. “In the depths of winter, for more than a month, we’ve had this area of open water,” says Kent Moore, professor of physics at the University of Toronto. “It’s just remarkable that this polynya went away for 40 years and then came back.” There are many who are blaming the appearance of the massive holes on climate change, which is one of the main culprits for many abrupt changes seen on the Antarctica continent in the last couple of years. However, scientists are yet to find a connection between climate change and the appearance of massive holes. Researchers from the SOCOM project are conducting a study of the massive hole which will hopefully provide more answers than questions. (H/T Motherboard) Using the MeerKAT radio telescope, an international team of astronomers has performed observations of a galaxy cluster designated SPT-CLJ2337−5942. The observational campaign revealed the presence of an ultra-steep spectrum radio halo in this cluster. The finding is presented in a paper published Sept. 9 on the arXiv preprint server.
