Security researchers have detailed the inner workings of the commercial Android spyware called Predator, which is marketed by the Israeli company Intellexa (previously Cytrox).

Predator was first documented by Google’s Threat Analysis Group (TAG) in May 2022 as part of attacks leveraging five different zero-day flaws in the Chrome web browser and Android.

The spyware, which is delivered by means of another loader component known as Alien, is equipped to record audio from phone calls and VoIP-based apps as well as gather contacts and messages, including from Signal, WhatsApp, and Telegram.

JIUQUAN — China sent three astronauts to its Tiangong space station on Tuesday, putting a civilian into orbit for the first time as it pursues plans to send a crewed mission to the Moon by the end of the decade.

The world’s second-largest economy has invested billions of dollars in its military-run space program in a push to catch up with the United States and Russia.

The Shenzhou-16 crew took off atop a Long March 2F rocket from the Jiuquan Satellite Launch Centre in northwest China at 9:31 am (0131 GMT), AFP journalists saw.

The 1st atomic bomb was nicknamed “gadget.”

Does this say something about who we are? Or does it say something about the nature of technology and the power to do good or evil?

Today we live in a universe of ever-more-powerful gadgets and humanity has never wielded more technological power because we live in the most scientifically advanced century in the history of our civilization. The paradox, however, is that ours is also the most dangerous century not only for countless other species going extinct but also for our own existence.

The AI “arms race” commences. Silicon Valley is looking to capitalize on AI’s big moment, and every tech Goliath worth its salt is feverishly looking to churn out a new product to keep pace with ChatGPT’s 100 million users. Microsoft kicked things off nicely earlier this month with its integration of ChatGPT into Bing, with Microsoft CEO Satya Nadella proclaiming, “The race starts today.” The OG tech giant says it wants to use the chatbot to “empower people to unlock the joy of discovery,” whatever that means. Not to be outdone, Google announced that it would be launching its own AI search integration, dubbed “Bard” (Google’s tool already made a mistake upon launch, costing the company a stock slump). In China, meanwhile, the tech giants Alibaba (basically the Chinese version of Amazon) and Baidu (Chinese Google) recently announced that they would also be pursuing their own respective AI tools.

Do the people actually want an AI “revolution”? It’s not totally clear but whether they want it or not, it’s pretty clear that the tech industry is going to give it to them. The robots are coming. Prep accordingly!

This device is a pulse magneto-fusion power system whose successors could produce electricity from the first commercial fusion reactor as early as 2028.

Creating a continuously controlled fusion reaction and not a thermonuclear bomb requires a confined environment where high densities and high temperatures can turn hydrogen gas into plasma. The luxury the Sun enjoys as a big ball of hydrogen comes from its enormous size and immense gravitational forces which serve to confine the ongoing nuclear fusion within it. But here on Earth, we need powerful magnets to replace the gravity confinement that the Sun provides. And it was thought until recently that our confinement efforts to create dense plasma faced a speed limit barrier that caused the field to break. We now know that what was called the Greenwald Limit no longer exists after experiments done at École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. So now the conditions to generate positive energy yields from controlled fusion means we are getting close to the first fusion reactors.

Enter Helion Energy and Pulse Fusion

Helion Energy is joining the lineup of companies and organizations bellying up to the fusion bar, backed by Open AI’s founder, Sam Altman and Microsoft. The latter has contracted Helion to provide power to the technology giant by 2028.

Creating the nuke bomb scene in Christopher Nolan’s Oppenheimer. In this video essay, I discuss how Christopher Nolan will film the atomic bomb scene in Oppenheimer, a biopic film on the real-life story of J. Robert Oppenheimer. Christopher Nolan’s Oppenheimer movie will change the movie landscape through its source material and also its filmmaking potential.

Oppenheimer is an upcoming American biographical film written and directed by Christopher Nolan. It is based on American Prometheus, a biography of J. Robert Oppenheimer written by Kai Bird and Martin J. Sherwin. The film is a co-production between Syncopy Inc. and Atlas Entertainment; Nolan produced the film alongside Emma Thomas and Charles Roven. Cillian Murphy leads an ensemble cast as Oppenheimer, the theoretical physicist who is among those credited with being the “father of the atomic bomb” for his role in the Manhattan Project—the World War II undertaking that developed the first nuclear weapons. The film stars Cillian Murphy, Emily Blunt, Florence Pugh, Robert Downey Jr., Matt Damon, Rami Malek, Benny Safdie, Josh Hartnett, Dane DeHaan, Jack Quaid, Matthew Modine, Dylan Arnold, David Krumholtz, Alden Ehrenreich, David Dastmalchian, Olli Haaskivi, Jason Clarke, James D’Arcy, Michael Angarano, Guy Burnet, Danny Deferrari, Matthias Schweighöfer, Gary Oldman, Harrison Gilbertson, Emma Dumont, Devon Bostick, Trond Fausa, Christopher Denham, Josh Zuckerman, Josh Peck and Olivia Thirlby.

Polynesians exposed to fallout from France’s nuclear tests in the South Pacific have a slightly increased risk of developing thyroid cancer, a study suggested on Monday that used declassified military data for the first time.

France carried out 41 atmospheric nuclear weapon tests in French Polynesia between 1966 and 1975, exposing residents to fallout which has been a source of lasting friction between Paris and residents of the Pacific archipelago.

The study, published in the journal JAMA Network Open, used risk modeling to estimate that the were associated with between 0.6 percent and 7.7 percent of in French Polynesia.

An aqueous lithium-ion battery would be safer than the ones being used in EVs today. So why aren’t car companies switching to it?

In the meantime, aqueous Li-ion technology is finding niche uses where limited resilience and longevity are less of an issue such as for the military.

Aqueous Li-ion Recyclability

If the fire and explosion issues aren’t enough to give battery developers reasons to look at other improvements, recyclability to reduce pollution should be high on the list. An aqueous Li-ion battery eliminates the use of toxic materials that require invasive and destructive methods to mine and transform for manufacturing. The processes are currently so complex and expensive that recycling Li-ion batteries is largely not done by companies that use them in EVs and other devices. Only recently have specialized Li-ion recyclers emerged like Li-Cycle, a Canadian-based company that announced the building of a new European recycling hub a few days ago. Changing the technology to aqueous Li-ion would make the job of recycling companies and the reuse of the recovered materials far more attractive.
