This work expands the repertoire of DNA-based recording techniques by developing a novel DNA synthesis-based system that can record temporal environmental signals into DNA with minutes resolution. Employing DNA as a high-density data storage medium has paved the way for next-generation digital storage and biosensing technologies. However, the multipart architecture of current DNA-based recording techniques renders them inherently slow and incapable of recording fluctuating signals with sub-hour frequencies. To address this limitation, we developed a simplified system employing a single enzyme, terminal deoxynucleotidyl transferase (TdT), to transduce environmental signals into DNA. TdT adds nucleotides to the 3’ ends of single-stranded DNA (ssDNA) in a template-independent manner, selecting bases according to inherent preferences and environmental conditions.

Taiwan Semiconductor Manufacturing Company makes 24% of all the world’s chips, and 92% of the most advanced ones found in today’s iPhones, fighter jets and supercomputers. Now TSMC is building America’s first 5-nanometer fabrication plant, hoping to reverse a decades-long trend of the U.S. losing chip manufacturing to Asia. CNBC got an exclusive tour of the $12 billion fab that will start production in 2024.

The tech giant wants to be known for more than social media’s ills.

Facebook is planning to change its company name next week to reflect its focus on building the metaverse, according to a source with direct knowledge of the matter.

The coming name change, which CEO Mark Zuckerberg plans to talk about at the company’s annual Connect conference on October 28th, but could unveil sooner, is meant to signal the tech giant’s ambition to be known for more than social media and all the ills that entail. The rebrand would likely position the blue Facebook app as one of many products under a parent company overseeing groups like Instagram, WhatsApp, Oculus, and more. A spokesperson for Facebook declined to comment for this story.

Facebook already has more than 10,000 employees building consumer hardware like AR glasses that Zuckerberg believes will eventually be as ubiquitous as smartphones. In July, he told The Verge that, over the next several years, “we will effectively transition from people seeing us as primarily being a social media company to being a metaverse company.”

The authors present a high-resolution palaeomagnetic record for a Late Cretaceous limestone in Italy. They claim that their record robustly shows a ~12° true polar wander oscillation between 86 and 78 Ma, with the greatest excursion at 84–82 Ma.

The authors propose a new framework, deep evolutionary reinforcement learning, evolves agents with diverse morphologies to learn hard locomotion and manipulation tasks in complex environments, and reveals insights into relations between environmental physics, embodied intelligence, and the evolution of rapid learning.

SpaceX is hoping to launch its first orbital Starship test flight in the next few months from its Starbase facility in Texas and a new video captures the company’s work so far on the massive rocket.

The 90-second montage, which SpaceX showed off on Twitter, offers views of the company’s massive Starship spacecraft being wheeled to the launch pad, taking off, performing complex flips and then landing safely on the ground. You also catch a glimpse of Earth from up high.

A NASA telescope might have found the first ever planet outside of our own Milky Way galaxy.

If confirmed, the world would be thousands of times further away than the many exoplanets we have found in our own galaxy so far.

Scientists were able to do so using NASA’s Chandra X-ray Observatory, using techniques that could allow for the search for other worlds to dramatically the amount of space it is able to scan.
