Asteroid Detection: New Method Uses James Webb Space Telescope and NVIDIA Accelerated Computing

Asteroids were responsible for extinction events hundreds of millions of years ago on Earth, providing no shortage of doomsday film plots for Hollywood. But researchers focused on asteroid tracking are on a mission to locate them for today’s real-world concerns: planetary defense.

The new and unexpected discovery tool applied in this research is NASA’s James Webb Space Telescope (JWST), which was tapped for views of these asteroids from previous research and enabled by NVIDIA accelerated computing.

Capturing Asteroid Images With Infrared JWST Driven by NVIDIA GPUs

Observatories typically look at the reflected light off asteroids to determine their size, which can be inaccurate. Using a telescope with infrared, like the JWST, can help track the thermal signals of asteroids for a more precise way at gauging their size.

Harnessing GPUs to Save the Planet From Asteroids

The 2024YR4 near-Earth asteroid — estimated as wide as 300 feet and capable of destroying a city the size of New York — has a 2.3% chance of striking Earth.

New Method for Detecting Small Asteroids

A new method for detecting small asteroids, developed by an international team of researchers, uses previous studies, asteroid synthetic movement tracking, and infrared observations. This method was applied to images of TRAPPIST-1, a star studied to search for signs of atmospheres around its seven terrestrial planets.

Conclusion

The new study used the JWST, the best-ever telescope in the infrared, on images of TRAPPIST-1, a star studied to search for signs of atmospheres around its seven terrestrial planets. The data include more than 10,000 images of the star. The researchers applied synthetic tracking methods, which doesn’t require previous information on an asteroid’s motion. Instead, it does "fully blind" search by testing possible shifts, like velocity vectors.

Elon Musk’s xAI: The Missing Piece in Open-Source AI Development

Grok 3: A New Era in AI Reasoning

Elon Musk’s xAI, the startup that owns the X social media platform and builds AI models, has unveiled its latest innovation, Grok 3. This AI model challenges the best from OpenAI in reasoning and other tasks. The unveiling follows Musk’s hostile bid for OpenAI, Inc., the non-profit that controls OpenAI, last week.

A Shift in Focus

Musk’s statement about the bid reads, "It’s time for OpenAI to return to the open-source, safety-focused force for good it once was." However, the question remains: If Elon Musk is concerned about keeping AI development transparent and safe, why hasn’t he committed xAI to open-source Grok for all of its models starting right now, in perpetuity?

The Open-Source Debate

The term "open-source AI models" is often misused, with the historical meaning of "open source" indicating the release of a program’s source code. In the case of open-source models, including Grok 1 and Meta’s Llama AI models, no source code is released. Instead, firms release only the model "parameters," or "weights," for a model. Because a lot can be re-constructed from having access to the weights, the AI field has been willing to bend the definition of open-source. Just know that this usage is not without controversy.

The Lack of Commitment

At press time, I had not received a reply to my request for comment from xAI or to my tweet on X directed at Musk, asking why he wouldn’t commit to open-sourcing all xAI models. The first model, Grok 1, was released in November of 2023 and made open-source the following March, a four-month lag. The company quickly followed with Grok 1.5 the same month, then Grok 2 this past August, and now Grok 3. That suggests there has been ample time to make Grok 1.5 and Grok 2 open-source if the company were to follow the same cadence.

Conclusion

Musk’s lack of a firm commitment or even a vague statement of principle is odd, given his professed concern for transparency in AI for humanity’s sake. By making a hostile bid for OpenAI, Musk seems to have shifted the burden of protecting humanity outside of his own corporate interests. Perhaps not surprising, since xAI has its own for-profit investors to please.

FAQs

Q: What is the difference between open-source and open-source AI models?
A: Open-source refers to the release of a program’s source code, while open-source AI models release only the model "parameters," or "weights," for a model.

Q: Why is Elon Musk’s lack of commitment to open-sourcing xAI models surprising?
A: It is surprising given his professed concern for transparency in AI development for the benefit of humanity.

Q: Can a company maintain a balance between making available open-source models and keeping other models closed?
A: Yes, companies can maintain a balance between making available open-source models and keeping other models closed, but it is unclear why xAI is not doing so.

Q: What is the significance of the xAI’s Grok 3 model?
A: Grok 3 is a new era in AI reasoning, challenging the best from OpenAI in reasoning and other tasks.

XCSSET Malware: A New Threat to Developers and Users

Microsoft has recently discovered a new variant of malware, known as XCSSET, which is targeting developers and users alike. This enhanced malware family has added new features to its arsenal, making it a more sophisticated and dangerous threat.

New Features and Capabilities

These enhanced features add to this malware family’s previously known capabilities, like targeting digital wallets, collecting data from the Notes app, and exfiltrating system information and files. XCSSET contains multiple modules for collecting and exfiltrating sensitive data from infected devices.

Detection and Mitigation

Microsoft Defender for Endpoint on Mac now detects the new XCSSET variant, and it’s likely other malware detection engines will soon, if not already. Unfortunately, Microsoft didn’t release file hashes or other indicators of compromise that people can use to determine if they have been targeted. A Microsoft spokesperson said these indicators will be released in a future blog post.

Prevention and Best Practices

To avoid falling prey to new variants, Microsoft said developers should inspect all Xcode projects downloaded or cloned from repositories. The sharing of these projects is routine among developers. XCSSET exploits the trust developers have by spreading through malicious projects created by the attackers.

Conclusion

XCSSET is a formidable threat that requires immediate attention from developers and users alike. By being aware of its capabilities and taking necessary precautions, we can minimize the risk of infection and prevent data breaches. It is essential to stay vigilant and keep our systems and software up to date to ensure we can detect and mitigate this malware effectively.
