Scientists have developed a model to better understand the physics of the powerful superflares emitted by stars far beyond our solar system.
Solar flares, which are rapid and strong bursts of energy and radiation that originate from the Sun’s surface, are known to be emitted into space by our Sun.
NASA’s Kepler and TESS missions, however, have discovered several stars may produce superflares that are 100–10,000 times brighter than those emitted by our Sun.

No specifications have been revealed, but officials have claimed that it surpasses the capabilities of the famous Tianhe-2 supercomputer.
The National Supercomputing Center (NSC) in Guangzhou, China, has unveiled the Tianhe Xingyi, a homegrown supercomputer, at an industrial event in Guangdong Province, which several media reports have confirmed. The NSC is the parent organization under whose guidance the Tianhe-2 supercomputer was also developed.
Supercomputers are a crucial component of a nation’s progress as they aid in solving the most complex and technical problems. The US has conventionally led the world in hosting the fastest supercomputers, as captured by the TOP500 listings, while also leading in the absolute number of supercomputers available to its researchers.
The high computing prowess of supercomputers can be used to carry out simulations for understanding climate change, carrying out material research, space exploration, and finding cures for various diseases. Of late, supercomputers have assumed importance for developing AI models, and access to advanced supercomputers could be critical in determining who leads the next frontier of information technology.
The tool uses first-principle calculations to arrive at material behavior in a few thousand steps rather than a million possibilities.
How well did the system perform?
The researchers have not yet put the system under extensive analysis but have seen some encouraging results in the limited cases so far.
For instance, when the framework was applied to a strontium titanium oxide or SrTiO3, perovskite material that has been studied using conventional methods for over three decades, the researchers found two new atomic configurations that have not been described before. Interestingly, one of the configurations identified earlier was deemed to be unstable by the framework.
Sam Altman says he got so many messages after being fired from OpenAI that his phone was unusable. The CEO was abruptly ousted by board members last month before being reinstated. Altman said the situation had been chaotic and confusing.

SpaceX is making significant progress in the development of the Starship V2, including new features and upcoming missions, while also facing competition and challenges in the space market.
Questions to inspire discussion.

Much like DALL-E 3, visitors to imagine.meta.com can provide a prompt, and Meta’s AI will offer several options. The image up top is a selection Meta AI created. If you’re wondering how Meta trained its AI to generate images, the company says it used 1.1 billion publicly visible Facebook and Instagram images.
That raises some questions about consent: after all, many of these images may have been uploaded before AI in its current form existed, and just because someone wanted to share their artwork with the world doesn’t mean they intended for it to train programs to create similar art. Permission to use art and written works for training AI is an ongoing question with evolving AI and has led to several lawsuits that are still working their way through the courts.
For now, the generated art Meta AI creates isn’t watermarked in a way that can’t be hidden. But Meta says it will roll out invisible watermarks soon that shouldn’t be so easy to cover up.
A beating heart makes for a formidable surgical arena, but a new robotic catheter could someday equip surgeons to operate in the cardiac environment with greater ease.
The device, designed by a team of physicians and engineers at Boston University, possesses shape-shifting capabilities that allow it to be maneuvered through complex anatomy while maintaining enough stability to accomplish surgical objectives within the heart.
In a study published in Science Advances, the authors demonstrated the robot’s ability to assist with two mock cardiac procedures using animal tissue. The study authors suggest that, with further development, the robotic catheter could make many common heart surgeries far safer and less taxing on the body.
The Hubble Space Telescope recently suffered a glitch that made it go into safe mode, so it has not been collecting new science data since November 23. But on Friday, December 8, NASA will attempt to get the telescope up and running again by tweaking the operation of one of its three gyros.
The gyros are responsible for keeping the telescope pointed in the right direction, and an error in one of them put the telescope into safe mode to prevent any damage occurring to its hardware. Although it is theoretically possible for the telescope to operate with just one gyro, this would be less efficient and observing time would be lost as it would take longer for the telescope to switch between targets. So ideally, all three gyros can be operational.
The problem with the telescope was first shared on November 29, when NASA announced it was performing tests to understand the issue. Now, the tests are complete and NASA plans to resume operations. “After analyzing the data, the team has determined science operations can resume under three-gyro control,” NASA wrote in a new update. “Based on the performance observed during the tests, the team has decided to operate the gyros in a higher-precision mode during science observations. Hubble’s instruments and the observatory itself remain stable and in good health.”
