AMD Helios is a rack-scale system solution for high-performance computing deployments that combines 72 Instinct MI455X accelerators with 31 TB of HBM4 memory in total. The system is designed to deliver up to 2.9 exaFLOPS of FP4 compute performance for AI inference and 1.4 exaFLOPS for AI training. Helios represents AMD's direct competition with NVIDIA's Vera Rubin platform in the enterprise AI infrastructure market, where data centers require massive computational power for training and deploying large language models and other AI applications.

The MI455X features 432GB of HBM4 memory per accelerator, which exceeds NVIDIA Rubin's 288GB capacity. This 2.25x increase in memory headroom provides AMD's clearest competitive advantage, enabling inference on larger AI models without requiring tensor parallelism—a technique that splits models across multiple GPUs. This reduces system complexity and interconnect demands, making it easier to deploy very large language models on AMD's infrastructure.

No. A Cochrane review analyzing 22 randomized controlled trials found that intermittent fasting produces little to no difference in weight loss compared to standard dietary advice. When intermittent fasting is compared to regular diets with calorie restriction, both approaches typically result in similar weight loss of around 7% over 6-12 months. The review concluded that intermittent fasting did not have a clinically meaningful effect on weight loss compared to traditional dietary advice or doing nothing.

Intermittent fasting has surged in popularity fueled by social media, lifestyle influencers, and claims of rapid weight loss and metabolic benefits. However, the evidence does not support these claims of superiority. While intermittent fasting can help people lose weight in the short term, this occurs primarily because people eat fewer calories overall—the same mechanism behind any successful diet. The hype around intermittent fasting has outpaced the actual scientific evidence supporting its effectiveness compared to other dietary approaches.

Neural watermarking is a technology that embeds digital markers into copyrighted music, allowing detection systems to identify when original songs have been used as training data or incorporated into AI-generated compositions. Unlike surface-level audio comparison that matches frequencies or waveforms, neural watermarking works by analyzing the deeper musical structure—including melodic patterns, chord progressions, and harmonic elements—to identify similarities even when songs are altered through changes in tempo, key, arrangement, or remixing. This enables platforms to trace the origin of musical elements and determine whether a song contains portions derived from copyrighted works, helping artists recognize their influence on AI tracks and establish grounds for potential compensation.

Identifying original songs within AI-generated music is crucial because AI music generation systems have been trained on vast collections of copyrighted music without permission, raising significant copyright infringement concerns. When AI systems generate new compositions, they may incorporate melodic fragments, chord sequences, or harmonic elements from their training data, creating derivative works that infringe on artists' intellectual property rights. By detecting these original songs embedded in AI-generated music, copyright holders can establish evidence of infringement, pursue legal action for compensation, and ensure that artists are properly credited and compensated for their work. This technology also helps distinguish between coincidental musical similarity and actual copying, providing nuance in determining whether infringement has occurred.

No, the Formula 1 channel is included in the base Apple TV subscription at no additional cost ($12.99 per month or $99 per year). However, streaming all 24 races in the 2026 season requires an active Apple TV subscription. The good news is that all practice sessions throughout the season are available to watch for free, and select race weekends will also be available free to non-subscribers.

Starting with the 2026 season, Apple TV became the exclusive broadcast partner for Formula 1 in the United States, meaning ESPN will no longer show any races. This five-year partnership runs through 2030 and replaces the previous broadcasting arrangement. While the standalone F1 TV Pro service is no longer the primary way to watch in the US, F1 TV Premium content is now available through Apple TV subscriptions at no extra charge.

Spaying female pets eliminates the risk of pyometra, a potentially deadly infection of the uterus, and dramatically reduces the incidence of breast cancer. Neutering and spaying also help prevent unwanted behaviors and reduce the likelihood of pets escaping to roam, which can lead to injury or disease.

Spaying and neutering can be expensive at traditional veterinary clinics, which prevents many pet owners from accessing these services. Operation Pawpulation addresses this by offering low-cost procedures, including programs where feral cats can be spayed, neutered, and vaccinated for just $20. The organization also partners with foundations like the Jason Heigl Foundation to offer free procedures periodically, removing financial obstacles to responsible pet ownership.

Blue Origin has shut down its suborbital space tourism business (New Shepard) to redirect resources toward its Blue Moon lunar lander program. The company is also focusing heavily on developing its New Glenn rocket. Additionally, Blue Origin's lunar lander was shipped to NASA's Johnson Space Center in Texas for thermal and vacuum testing as part of its development pathway toward an uncrewed mission to the lunar surface planned for 2026.

Blue Origin is developing crewed lunar systems that may not require orbital refueling, whereas SpaceX's Starship lunar lander relies on a novel in-orbit refueling process that still requires demonstration and refinement. This difference in approach means Blue Origin could potentially land humans on the moon before SpaceX, as the company's method may involve fewer complex technical steps. Additionally, Blue Origin is exploring a hybrid Mk1–Mk2 lander approach that could offer NASA a faster, lower-risk option for the Artemis III mission.

Previously purchased movies and TV shows remain fully accessible through the Apple TV app, where all iTunes content has been consolidated.

The iTunes Wish List feature is discontinued and removed from tvOS 26.4 on Apple TV; Apple recommends migrating items to the TV app's Watchlist, with email notifications providing migration links.

Google I/O is an annual developer conference held by Google since 2007 that showcases the company's newest products, technologies, and innovations in AI, Android, and other areas. At the event, in-person and virtual attendees learn about upcoming innovations and feature announcements that shape the future of Google's ecosystem.

Yes, Google I/O offers both in-person and virtual attendance options. Virtual attendance is typically free and allows attendees outside the US to participate in keynotes and sessions online, though in-person attendance may require lottery registration with limited tickets available.

A recovery seed phrase is a sequence of 12 to 24 words that serves as the master key to your cryptocurrency wallet[2][4]. If you lose access to your wallet due to a lost, stolen, or damaged device, this phrase allows you to recreate your wallet and regain access to all your funds[1]. The recovery phrase is so critical because anyone who obtains it gains full access to all your cryptocurrency assets[2][3]. Unlike a password that can be reset, losing your recovery phrase means losing access to your crypto permanently[2].

Recovery seed phrases should never be stored digitally because digital storage methods—including email, cloud services, password managers, screenshots, and plain text files—are vulnerable to hacking, malware, and data breaches[1][2][3][5]. Similarly, sharing your recovery phrase online or with anyone (except someone you would trust with your entire cryptocurrency portfolio) creates an immediate risk of theft[2][3]. Legitimate wallet providers and crypto institutions will never ask you for your recovery phrase, so any online request for it is almost certainly a phishing scam[3]. The safest approach is to write your recovery phrase on paper and store it offline in a secure physical location[1][2].
