Researchers from the University of New South Wales (UNSW) in Australia have discovered an amazing material that does not expand or contract over an extremely wide temperature range, making it one of the most stable materials known. A team led by UNSW A/Prof Neeraj Sharma found that the zero thermal expansion material, made of scandium, aluminium, tungsten and oxygen, did not change in volume from 4 to 1400 Kelvin (-269 to 1126 °Celsius).

Unlike other pens, the Erasable Circuit Marker lets you draw with conductive ink that can light up special sheets of paper. This means that soldering and creating electronic circuits may become a breeze due to the electrical connections. That’s right, you’re able to draw electric circuits quickly and easily, thanks to the company’s patented AgIC nanoparticle silver ink. When two points connect on a sheet of paper, you’re able to create a working electric connection. Read more for two videos and additional information.

Nicknamed Cooper due to where it was found and scientifically classified as Australotitan cooperensis, this newly discovered dinosaur species is now among the 15 largest ever found worldwide. It measures approximately 16-21 feet tall and up to 98-feet long, which makes it as large as a basketball court. How did this dinosaur look? The team says it was most likely a giant sauropod, or a plant-eating subgroup characterized by their elongated necks, long tails and four trunk-like legs.

Samsung has been developing flexible displays for years, and their most recent innovation is stretchable PPG heart rate sensors combined with OLED display systems. This electronic skin is worn on the inner wrist near the radial artery, and during their tests, the OLED display continued to work stably even after being stretched 1,000 times. As for accuracy, the measurements recorded from a moving wrist by the sensor was found to pick up a heartbeat signal that 2.4-times stronger than would be picked up by a fixed silicon sensor.

Russia has declassified footage of the world’s largest nuclear explosion, or to be more specific, when the former Soviet Union detonated “Tsar Bomba” nearly 60 years ago. This hydrogen bomb carried the force of 50 million tons of conventional explosives and was detonated in a test on October 30, 1961 over the remote Novaya Zemlya archipelago above the Arctic Circle. The rarely seen footage depicts a massive fireball and a 60-km high mushroom cloud rising after the explosion, captured from several angles by cameras installed on the ground as well as on board two Soviet aircraft.

Ganymede is the largest known moon in our solar system and the only one with its own magnetic field, which causes auroras, or ribbons of glowing, electrified gas, in regions circling its poles. NASA’s Juno will come within 645 miles (1,038 kilometers) of the surface of Ganymede on Monday, June 7, at 1:35 p.m. EDT, and this flyby will be the closest a spacecraft has come to the solar system’s largest natural satellite since Galileo made a close approach back on May 20, 2000.

A team of researchers from the Massachusetts Institute of Technology (MIT) have developed a programmable fiber with digital capabilities that can sense, store, analyze, and gather activities after it’s woven into fabric. Yoel Fink, professor and principal investigator at the Research Laboratory of Electronics and a senior author on the study, says that these digital fibers not only enhance the possibilities of uncovering the context of hidden patterns in a human body, but cna also be used to monitor physical performance, medical inference, as well as help detect diseases at an early stage.

NASA has just selected two new missions to Venus: DAVINCI+ (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) and VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy). Each mission will be awarded $500-million for development and expected to launch between 2028 – 2030. DAVINCI+ is set to measure the composition of Venus’ atmosphere to understand how it formed and evolved, as well as determine whether the planet ever had an ocean.

Thanks to new ultra-thin metal electrodes, researchers have created semitransparent perovskite solar cells that are highly efficient and can be coupled with traditional silicon cells to greatly boost the performance of both devices. This represents a big step towards developing completely transparent solar cells. Typically, these cell are made from silicon, but these new ones offer a promising alternative.

Technological singularity basically refers to a point in time at which technological growth becomes uncontrollable, resulting in unforeseeable changes to human civilization, with the most popular version of this being an AI agent that eventually enters a “runaway reaction” of self-improvement cycles. This means that each new and more intelligent generation appears more rapidly, resulting in a powerful superintelligence that qualitatively far surpasses all human intelligence. Read more to see how AI is now quickly learning to create itself.
