Submission + - Is there life on Enceladus?

Submitted by thephydes
thephydes writes: Enceladus is one of 146 moons of Saturn — discovered in1789 by William Herschel. It does have the potential to host life as we know it, according to Prof Michelle Dougherty.

“Enceladus has three key ingredients that are considered to be essential for the appearance of life,” said astronomer Prof Michele Dougherty of Imperial College London. “It has got liquid water, organic material and a source of heat. That combination makes it my favourite moon in the whole solar system.”

To investigate this possibility, ESA is considering a mission to more closely study the moon.

Submission + - 3-D Printed Rocket Engine Blasts Off In India (ieee.org)

Submitted by cusco
cusco writes: Indian company Agnikul used a 3-D printer from German company EOS to print the engine in one solid piece over the course of 72 hours. While other companies are using 3-D printers extensively this is the first one-piece engine printed. The advantages of this approach, besides speed of construction, include elimination of the welds that so frequently cause engine failure. The single-engine technology demonstration rocket produced 6 kilonewtons of thrust, and was used in a configuration roughly equivalent to the company's future second stage. Their planned commercial product will have 7 of these engines in the first stage, launching the single-engine second stage. https://spectrum.ieee.org/3d-p...

Assembling the rest of the rocket and integrating the engine took roughly two weeks. The company says that opens the door to providing low-cost, “on-demand” launch services to operators of small satellites, which otherwise need to wait for a ride share on a bigger rocket.

The big challenge now will be going from a single engine to a cluster of seven on Agnibaan’s first stage, says cofounder and CEO Srinath Ravichandran. This raises all kinds of challenges, from balancing thrust across the engines at lift-off to managing engine plume interactions when the engines gimbal to alter the trajectory. “But these are problems that people have figured out,” he says. “We believe that we should just be able to fine-tune it for our mission and go.”

The company is currently building facilities to carry out ground tests of engine clusters, says Ravichandran, and is targeting its first orbital launch for this time next year.

Submission + - China State Hackers Infected 20,000 Fortinet VPNs, Dutch Spy Service Says (arstechnica.com)

Submitted by Anonymous Coward
An anonymous reader writes: Hackers working for the Chinese government gained access to more than 20,000 VPN appliances sold by Fortinet using a critical vulnerability that the company failed to disclose for two weeks after fixing it, Netherlands government officials said. The vulnerability, tracked as CVE-2022-42475, is a heap-based buffer overflow that allows hackers to remotely execute malicious code. It carries a severity rating of 9.8 out of 10. A maker of network security software, Fortinet silently fixed the vulnerability on November 28, 2022, but failed to mention the threat until December 12 of that year, when the company said it became aware of an “instance where this vulnerability was exploited in the wild.” On January 11, 2023—more than six weeks after the vulnerability was fixed—Fortinet warned a threat actor was exploiting it to infect government and government-related organizations with advanced custom-made malware.

Submission + - The Rise and Fall of BNN Breaking, an AI-Generated News Outlet (nytimes.com)

Submitted by Anonymous Coward
An anonymous reader writes: The news was featured on MSN.com: “Prominent Irish broadcaster faces trial over alleged sexual misconduct.” At the top of the story was a photo of Dave Fanning. But Mr. Fanning, an Irish D.J. and talk-show host famed for his discovery of the rock band U2, was not the broadcaster in question. “You wouldn’t believe the amount of people who got in touch,” said Mr. Fanning, who called the error “outrageous.” The falsehood, visible for hours on the default homepage for anyone in Ireland who used Microsoft Edge as a browser, was the result of an artificial intelligence snafu. A fly-by-night journalism outlet called BNN Breaking had used an A.I. chatbot to paraphrase an article from another news site, according to a BNN employee. BNN added Mr. Fanning to the mix by including a photo of a “prominent Irish broadcaster.” The story was then promoted by MSN, a web portal owned by Microsoft. The story was deleted from the internet a day later, but the damage to Mr. Fanning’s reputation was not so easily undone, he said in a defamation lawsuit filed in Ireland against Microsoft and BNN Breaking. His is just one of many complaints against BNN, a site based in Hong Kong that published numerous falsehoods during its short time online as a result of what appeared to be generative A.I. errors.

Mr. Fanning’s complaint against BNN is one of many. The site based published numerous falsehoods during its short time online.Credit...Paulo Nunes dos Santos for The New York Times BNN went dormant in April, while The New York Times was reporting this article. The company and its founder did not respond to multiple requests for comment. Microsoft had no comment on MSN’s featuring the misleading story with Mr. Fanning’s photo or his defamation case, but the company said it had terminated its licensing agreement with BNN. During the two years that BNN was active, it had the veneer of a legitimate news service, claiming a worldwide roster of “seasoned” journalists and 10 million monthly visitors, surpassing the The Chicago Tribune’s self-reported audience. Prominent news organizations like The Washington Post, Politico and The Guardian linked to BNN’s stories. Google News often surfaced them, too. A closer look, however, would have revealed that individual journalists at BNN published lengthy stories as often as multiple times a minute, writing in generic prose familiar to anyone who has tinkered with the A.I. chatbot ChatGPT. BNN’s “About Us” page featured an image of four children looking at a computer, some bearing the gnarled fingers that are a telltale sign of an A.I.-generated image.

Comment Re:Is this something for non-embedded usage? (Score 1) 8

In order to make proper use of this, I guess you would want to set CPU-affinity per process (or for a specific interrupt), balance it, and increase (or decrease) the core frequency. I wonder if there is any desktop case for such precision control.

In that case I would wonder on the power requirement.

Submission + - IBM Open-Sources Its Granite AI Models (zdnet.com)

Submitted by Anonymous Coward
An anonymous reader writes: IBM managed the open sourcing of Granite code by using pretraining data from publicly available datasets, such as GitHub Code Clean, Starcoder data, public code repositories, and GitHub issues. In short, IBM has gone to great lengths to avoid copyright or legal issues. The Granite Code Base models are trained on 3- to 4-terabyte tokens of code data and natural language code-related datasets. All these models are licensed under the Apache 2.0 license for research and commercial use. It's that last word — commercial — that stopped the other major LLMs from being open-sourced. No one else wanted to share their LLM goodies.

But, as IBM Research chief scientist Ruchir Puri said, "We are transforming the generative AI landscape for software by releasing the highest performing, cost-efficient code LLMs, empowering the open community to innovate without restrictions." Without restrictions, perhaps, but not without specific applications in mind. The Granite models, as IBM ecosystem general manager Kate Woolley said last year, are not "about trying to be everything to everybody. This is not about writing poems about your dog. This is about curated models that can be tuned and are very targeted for the business use cases we want the enterprise to use. Specifically, they're for programming."

These decoder-only models, trained on code from 116 programming languages, range from 3 to 34 billion parameters. They support many developer uses, from complex application modernization to on-device memory-constrained tasks. IBM has already used these LLMs internally in IBM Watsonx Code Assistant (WCA) products, such as WCA for Ansible Lightspeed for IT Automation and WCA for IBM Z for modernizing COBOL applications. Not everyone can afford Watsonx, but now, anyone can work with the Granite LLMs using IBM and Red Hat's InstructLab.

Submission + - First Person To Receive a Genetically Modified Pig Kidney Transplant Dies (npr.org)

Submitted by Anonymous Coward
An anonymous reader writes: Richard "Rick" Slayman, the first human to receive a genetically modified pig kidney transplant, has died almost two months after the procedure. Slayman, who had end-stage kidney disease, underwent the transplant in March at Massachusetts General Hospital in Boston at age 62. The hospital said in a statement on Saturday that there was "no indication" that his death was the result of the transplant. The transplant surgeon had said he hoped the transplant would function for at least two years.

"The Mass General transplant team is deeply saddened at the sudden passing of Mr. Rick Slayman," read the hospital statement. "Mr. Slayman will forever be seen as a beacon of hope to countless transplant patients worldwide and we are deeply grateful for his trust and willingness to advance the field of xenotransplantation." The surgery was a milestone for the field of xenotransplantation — the transplant of organs from one species to another — as a way to alleviate the organ shortage for people who need transplants. The effort to genetically modify animal organs is in hopes that the human body will not reject the foreign tissue.

Submission + - Minor car crashes mean high tech repairs (cnn.com)

Submitted by smooth wombat
smooth wombat writes: With all the improvements in car safety over the decades, the recent addition of a plethora of high tech sensors and warnings comes with increased costs. And not just to have to have them on your car. Any time you get into an accident, even a minor one, it will most likely require a detailed examination of any sensors which may have been affected and their subsequent realignment, replacement, and calibration.

Some vehicles require “dynamic calibration,” which means, once the sensors and cameras are back in place, a driver needs to take the vehicle out on real roads for testing. With proper equipment attached the car can, essentially, recalibrate itself as it watches lane lines and other markers. It requires the car to be driven for a set distance at a certain speed but weather and traffic can create problems.

“If you’re in Chicago or L.A., good luck getting to that speed,” said Ebrahimi ”or if you’re in Seattle or Chicago or New York, with snow, good luck picking up all the road markings.”

More commonly, vehicles need “static calibration,” which can be done using machinery inside a closed workshop with a flat, level floor. Special targets are set up around the vehicle at set distances according to instructions from the vehicle manufacturer.

“The car [views] those targets at those specific distances to recalibrate the world into the car’s computer,” Ebrahimi said.

These kinds of repairs also demand buildings with open space that meet requirements including specific colors and lighting. And it requires special training for employees to perform these sorts of recalibrations, he said.

Submission + - Apple's iPhone Spyware Problem Is Getting Worse (wired.com)

Submitted by Anonymous Coward
An anonymous reader writes: In April, Apple sent notifications to iPhone users in 92 countries,warningthem they’d been targeted with spyware. “Apple detected that you are being targeted by a mercenary spyware attack that is trying to remotely compromise the iPhone associated with your Apple ID,” the notification reads. Users quickly took to social media sites including X, trying to work out what the notification meant. Many of thosetargetedwere based inIndia, but others in Europe alsoreportedreceiving Apple’s warning. Weeks later, little is still known about the latest iPhone attacks. Former smartphone giant Blackberry, now a security firm, has released research indicating they are linked to a Chinese spyware campaign dubbed “LightSpy,” but Apple spokesperson Shane Bauer says this is inaccurate.

While Apple says the latest spyware notifications aren't linked to LightSpy, the spyware remains a growing threat, particularly to people who may be targeted in Southern Asia, according to Blackberry's researchers. Described as a “sophisticatediOS implant,” LightSpy first emerged targeting Hong Kong protesters in 2020. However, the latest iteration is much more capable than the first. “It is a fully-featured modular surveillance toolset that primarily focuses on exfiltrating victims’ private information, including hyper-specific location data and sound recording during voice over IP calls,” the researchers wrote. April's warnings were not the first time Apple has issued notifications of this kind. The iPhone maker has sent out alerts to people in over 150 countries since 2021 as spyware continues to target high-profile figures across the globe.

Spyware can be weaponized by nation-state adversaries—but this is relatively rare and expensive. Its deployment is typically highly targeted against a very specific group of people, including journalists, political dissidents, government workers, and businesses in certain sectors. “Such attacks are vastly more complex than regular cybercriminal activity and consumer malware, as mercenary spyware attackers apply exceptional resources to target a very small number of specific individuals and their devices,” Applewrotein an advisory in April. "Mercenary spyware attacks cost millions of dollars and often have a short shelf life, making them much harder to detect and prevent. The vast majority of users will never be targeted by such attacks.” Plus, Apple says itsLockdown Modefeature can successfully protect against attacks. “As we have said before, we are not aware of anyone using Lockdown Mode being successfully attacked with mercenary spyware,” Bauer says. Still, for those who are targeted and caught unaware, spyware is extremely dangerous.
