Starship, which stands 394 feet (120 meters) tall, produces 16.7 million pounds (74.3 Meganewtons) of thrust, more than double that of the Saturn V rockets used to send Apollo astronauts to the Moon. The US Federal Aviation Administration (FAA) on Wednesday authorized SpaceX to carry out its second launch of Starship, the most powerful rocket ever built, after a first attempt in April ended in a spectacular explosion. In a statement, the FAA said Elon Musk’s company had now “met all safety, environmental, policy and financial responsibility requirements” following the mishap that marred the first orbital test flight of its…

Our DNA is not indestructible. Throughout the course of our lives, DNA can break in response to natural and environmental factors. Thankfully, our bodies have dedicated enzymes and pathways which can glue our broken DNA back together through several different mechanisms, known as DNA repair pathways. Some cancers, however, can hijack these pathways for their own benefit. Susanna Stroik, PhD, and Dale Ramsden, PhD, both researchers in the Department of Biochemistry and Biophysics in the UNC School of Medicine and the UNC Lineberger Comprehensive Cancer Center, have pieced together the lesser-known DNA repair pathway, called polymerase theta-mediated end joining (TMEJ).…

NASA Administrator Bill Nelson announced Wednesday Jim Free’s promotion to associate administrator for the agency at NASA Headquarters in Washington, effective when his predecessor Bob Cabana retires on Sunday, Dec. 31. Since September 2021, Free has served as the associate administrator for NASA’s Exploration Systems Development Mission Directorate (ESDMD).   Nelson also announced Free’s deputy, Catherine Koerner, will succeed him as the next head of the mission directorate.  “So many of us in the NASA family have worked with Jim and have been inspired by his character and intellect. Pam, Bob, and I strongly believe that his wealth of experience and…

A quick scan of the headlines makes it seem like generative artificial intelligence is everywhere these days. In fact, some of those headlines may actually have been written by generative AI, like OpenAI’s ChatGPT, a chatbot that has demonstrated an uncanny ability to produce text that seems to have been written by a human. But what do people really mean when they say “generative AI?” Before the generative AI boom of the past few years, when people talked about AI, typically they were talking about machine-learning models that can learn to make a prediction based on data. For instance, such…

On the other hand, coding today is a highly skilled, well-paid job, and there’s some concern that AI could effectively automate it. Nadella argues that skilled programmers will remain in demand, but that their jobs will change and even more jobs will become available. Nadella has said he envisions 1 billion developers creating on its platforms, many of them with little to no previous experience with coding.    Anytime you have something as disruptive as this, you have to think about the displacement and causes. And that means it’s all about upskilling and reskilling, and in an interesting way, it’s more…

Everything’s coming up Copilot — including Bing. Today at Microsoft Ignite 2023, the company renamed Bing Chat, the AI-powered chatbot it launched on Bing earlier this year, to Copilot in Bing. Meanwhile, the premium, corporate-focused version of Bing Chat, which was previously called Bing Chat Enterprise, has also been rebranded to Copilot. Why the name changes? Not to cause confusion, Microsoft swears — despite the fact that the company now has roughly a dozen products that share the Copilot brand. “Renaming ‘Bing Chat Enterprise’ to ‘Copilot’ reflects our vision to create a unified Copilot experience for consumer and commercial customers,”…

With 3D inkjet printing systems, engineers can fabricate hybrid structures that have soft and rigid components, like robotic grippers that are strong enough to grasp heavy objects but soft enough to interact safely with humans. These multimaterial 3D printing systems utilize thousands of nozzles to deposit tiny droplets of resin, which are smoothed with a scraper or roller and cured with UV light. But the smoothing process could squish or smear resins that cure slowly, limiting the types of materials that can be used.  Researchers from MIT, the MIT spinout Inkbit, and ETH Zurich have developed a new 3D inkjet…

We are introducing OpenAI Data Partnerships, where we’ll work together with organizations to produce public and private datasets for training AI models.Modern AI technology learns skills and aspects of our world — of people, our motivations, interactions, and the way we communicate — by making sense of the data on which it’s trained. To ultimately make AGI that is safe and beneficial to all of humanity, we’d like AI models to deeply understand all subject matters, industries, cultures, and languages, which requires as broad a training dataset as possible. Including your content can make AI models more helpful to you by…

The Hollywood heartthrob revealed his new ink during his concert in Edmonton, Canada on November 14, as reported by Just Jared. A couple of the new designs featured the dates of birth for both of his daughters Willa, 3, and Delphine, 1, respectively. @briannabaustad i actually dont know how im still alive after this #jonasbrothers #jonasbrothersconcert #jonasbrotherstour #joejonas #joejonasfans #jonas #jobros #edmonton #rogersplace ♬ original sound – bri In a fan-made video shared via…

One of the more unexpected products to launch out of the Microsoft Ignite 2023 event is a tool that can create a photorealistic avatar of a person and animate that avatar saying things that the person didn’t necessarily say. Called Azure AI Speech text to speech avatar, the new feature, available in public preview as of today, lets users generate videos of an avatar speaking by uploading images of a person they wish the avatar to resemble and writing a script. Microsoft’s tool trains a model to drive the animation, while a separate text-to-speech model — either prebuilt or trained on…
