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.

Sam Altman told Trevor Noah during a podcast appearance that he was inundated with messages in the chaotic aftermath of his firing.

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 .

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 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.”

SpaceX has shared spectacular new footage of last month’s launch of the most powerful rocket ever to fly.

The cinematic content (see video below) shows the first-stage Super Heavy booster and the Starship spacecraft (collectively known as the Starship) blasting skyward in the second integrated test flight of the vehicle, which could one day carry astronauts to the moon, Mars, and beyond.

Scientists have pinpointed the location of the place where an asteroid hit Earth approximately 750,000 years ago.

In a study published in Proceedings of the National Academy of Sciences, the planetary scientists released evidence showing that the location of impact crater they have been seeking for decades is on the Bolaven Plateau in southern Laos.
