Cygnus space freighter arrives at space station with 8,200 pounds of cargo aboard

Posted by in category: space

The Cygnus NG-19 cargo freighter arrived at the International Space Station on Friday, Aug. 4, after a two-day space ride with 8,200 pounds (3,700 kilograms) of supply, experiments and new technology aboard.

The craft, built by U.S. aerospace giant Northrop Grumman and named after astronaut Laurel Clark who perished during the Columbia space shuttle disaster in 2003, was the last to launch on a version of the company’s Antares rocket using a first stage built in Ukraine.

Chinese tech giant Alibaba challenges Meta with open-sourced A.I. model launch

Posted by in category: robotics/AI

In April, Alibaba launched its large language model (LLM) called Tongyi Qianwen. A LLM is an artificial intelligence model trained on huge amounts of data. It is also the basis for generative AI applications, such as ChatGPT — which generate human-like responses to user prompts.

Tongyi Qianwen allows AI content generation in English and Chinese and has different model sizes, including seven billion parameters and above. A model’s parameters refer to its power.

Alibaba will be open-sourcing the seven-billion-parameter model called Qwen-7B, along with a version designed for conversational apps, called Qwen-7B-Chat. This means that researchers, academics and companies globally can use the model to create their own generative AI apps without needing to train their own systems, saving time and expense. Companies with more than 100 million monthly active users will require a royalty-free license from Alibaba to do so.

Dr. Joshua Tewksbury, Ph.D. — Director, Smithsonian Tropical Research Institute (STRI)

Posted by in categories: biological, climatology, education, sustainability

Is the Ira Rubinoff Director of the Smithsonian Tropical Research Institute (STRI https://www.si.edu/about/bios/joshua-tewksbury), part of the Smithsonian Institution, the world’s largest museum, education, and research complex. He oversees more than 400 employees, with an annual budget of $35 million. Headquartered in Panama City, Panama, with field sites around the world, STRI furthers the understanding and public awareness of tropical biodiversity and its importance to human welfare. In addition to its resident scientists and support staff, STRI’s facilities are used annually by some 1,400 visiting scientists, pre-and postdoctoral fellows and interns from around the world.

Dr. Tewksbury is an ecologist with more than two decades of research in conservation and biodiversity, as well as nearly a decade of executive leadership experience at international research institutes.

Worldcoin and Kenyan Argue About Who’s Breaking Up With Whom

Posted by in categories: cryptocurrencies, privacy

Kenya claims it’s shutting down Sam Altman’s eyeball-scanning Worldcoin cryptocurrency within its borders — but Worldcoin says it’s suspending its own services in the country, thank you very much.

In a joint statement, a group of agencies in the East African nation said that Worldcoin “must cease its data collection activities in Kenya until further notice” as it investigates regulatory concerns about the way the project collects biometric data.

Worldcoin, meanwhile, seems to have a different version of events.

This Bangladesh Hacktivist Group Targets Critical Infrastructure — and It Isn’t Trying to Hide

A hacktivist group called “Mysterious Team Bangladesh” attacked over 750 times this year using the DDoS (Distributed Denial of Service) method and defaced over 70 websites. According to research performed by cyber security firm Group-IB, they seem to be driven by political and religious reasons.

“Mysterious Team Bangladesh” was founded in 2020 by a threat actor nicknamed “D4RK TSN” and is it unclear whether it originates from Bangladesh. Their activity peaked in May of 2023 after announcing a large-scale campaign against India.

Waves of charge signal rare physics at work inside a superconductor

Posted by in categories: materials, particle physics

“A place for everything and everything in its place”—making sense of order, or disorder, helps us understand nature. Animals tend to fit nicely into categories: Mammals, birds, reptiles, whatever an axolotl is, and more. Sorting also applies to materials: Insulator, semiconductor, conductor, and even superconductor. Where exactly a material lands in the hierarchy depends on a seemingly invisible interplay of electrons, atoms, and their surroundings.

Unlike animals, the boundaries are less sharp, and tweaking a material’s environment can force it to bounce between categories. For example, dialing down the temperature will turn some into superconductors. Snapping on a might reverse this effect. Within a single category, different types of order, or phases, can emerge from the sea of particles.

Unfortunately, we can’t see this nanoscopic universe with our eyes, but scientists can use advanced imaging tools to visualize what’s going on. Every once in a while, they uncover unexpected and surprising behaviors.

Webb Space Telescope captures stunning shots of Ring Nebula

Posted by in categories: materials, space travel

The main ring is surrounded by a faint halo and with many delicate structures. The interior of the ring is filled with hot gas. The star which ejected all this material is visible at the very center. It is extremely hot, with a temperature in excess (NASA, ESA, CSA, JWST Ring Nebula Team photo; image processing by Roger Wesson)

The images were released Thursday by an international team of astronomers, including three from the Canadian Western University’s Institute for Earth and Space Exploration.

Amazon Just Signaled It’s Serious About Dominating This $600 Billion Industry

Posted by in categories: business, materials

For a company the size of Amazon, it takes a lot to move the needle. It’s hard to enter new businesses that have enough upside to make a material difference. Advertising is one of them. With its recent change to break out results for its advertising business, Amazon is signaling it’s all in on staking its claim to as much of the market as it can.

That market is growing, but Amazon’s business is growing much faster. That means it’s taking share away from its competitors. Amazon is already the third-largest advertising platform. I wouldn’t bet against it someday soon becoming the biggest.
