The U.S. Space Force has certified United Launch Alliance's Vulcan Centaur rocket for national security missions after successful test flights and resolution of a booster nozzle issue. This certification allows ULA to join SpaceX in conducting launches under the National Security Space Launch program, with Vulcan missions expected to begin this summer. SpaceNews reports: "Thank you to all our customer partners who have worked hand-in-hand with us throughout this comprehensive certification process. We are grateful for the collaboration and excited to reach this critical milestone in Vulcan development," said Tory Bruno, president and chief executive of United Launch Alliance in a ULA statement about the vehicle's certification.
Bruno said at the roundtable that the next launch by ULA will be of its Atlas 5, carrying a set of Project Kuiper broadband satellites for Amazon. That launch is expected as soon as next month. He said then that would be followed by the first two Vulcan national security launches, missions designated USSF-106 and USSF-87. ULA did not give a schedule for those upcoming Vulcan launches but Space Systems Command, in a summary accompanying its press release, said the first NSSL mission on Vulcan is planned for the summer. Bruno said at the roundtable that the payloads for those missions have "complex processing" requirements beyond a typical mission, and did not state how long it would take them to be ready for a launch.
Bruno said ULA is projecting a dozen launches this year, split roughly evenly between Atlas and Vulcan and between national security and commercial missions. ULA has been stockpiling components, such as BE-4 engines and solid rocket boosters, needed for those missions. "We're all staged up and ready, and as spacecraft show up, we'll be able to fly them," he said. He noted the company wants to get to a "baseline tempo" of two launches a month by the end of this year and perform 20 launches next year.

Scientists in China successfully transplanted a genetically modified pig liver into a brain-dead patient, where it functioned for 10 days. The liver, modified to reduce immune rejection, produced key proteins and bile, showing compatibility and offering hope for future short-term xenotransplants. The Guardian reports: The surgery, at a Chinese hospital last year, is thought to mark the first time a pig liver has been transplanted into a human. It raises the prospect of pig livers serving as a "bridging organ" for patients on the waiting list for a transplant or to support liver function while their own organ regenerates. [...] The latest procedure was carried out in a 50-year-old man diagnosed with brain death after a severe head injury. The patient's own liver was intact and, in a surgery that took more than 10 hours, the organ taken from a genetically modified Bama miniature pig was plumbed into his blood supply as an additional liver.
The pig had six genetic modifications aimed at preventing immune rejection. These included deactivating genes that contribute to the production of sugars on the surface of pig cells, which the human immune system attacks, and introducing genes that express human proteins to "humanize" the liver. After the transplant, the pig liver showed signs of functioning, including producing bile, which helps break down fats in the digestive system, and porcine albumin, a blood protein. The team behind the advance, described in the journal Nature, said it was not clear whether the liver would have been able to fully support the patient, given that he had an existing liver and because the liver was removed after 10 days at the request of his family.

The Amtrak Guest Rewards Preferred Mastercard, issued by First National Bank of Omaha (FNBO), offers a variety of perks for Amtrak riders. It also currently has a 40,000 points limited-time offer that is worth up to roughly $1,000 value in Amtrak train fare or $400 in Amazon gift cards. This boosted offer came around the same time last year. Here are the highlights:
- 40,000 bonus points after spending $2,000 in the first 3 billing cycles of account opening.
- Roundtrip companion coupon upon account opening and card anniversary.
- One-class upgrade upon account opening and card anniversary.
- Station Lounge pass upon account opening and card anniversary.
- 3X points per $1 spent on Amtrak travel, including onboard purchases.
- 2X points per $1 spent on dining, travel, transit and rideshare.
- 1X point per $1 spent on all other purchases.
- 5% Amtrak Guest Rewards point rebate when you book your Amtrak redemption travel.
- 20% rebate on food and beverage purchases on board, via statement credit on this card.
- 1,000 Tier Qualifying Points (TQPs) every time you make at least $5,000 in purchases in a calendar year, up to 4,000 TQPs
- Amtrak points will not expire as long as your card account is open.
- No foreign transaction fees.
- $99 annual fee.
This offer is not going to be attractive for everyone, but it can be very valuable if you either enjoy recreational train travel or if you can use it for your commuting needs.
Amtrak points are currently worth roughly 2.5 cents per points towards Amtrak train fare. That means 40,000 points is worth approximately $1,000 in Amtrak train fare. Amtrak redemptions are variable and directly-linked to the cash cost, so you can use points on basically any ticket. There is also the potential value of the companion coupon, lounge pass, and one-class upgrade.
The best value is for train fare, but Amtrak points do transfer to certain other hotel programs, although some require elite status in those programs.
Gift cards. You can also redeem for various gift cards at a rate of 5,000 points = $50 gift card. So 40,000 points would get you $400 in gift cards to Amazon, Apple, Best Buy, Target, Walmart, etc.
You could take the train across the entire country! There is an 18-hour Capitol Limited overnight train from Washington D.C. to Chicago in a “Superliner Bedroom” with a private bathroom.
You could then take the 3-day, 2-night trip on the California Zephyr from Chicago to San Francisco. Enjoy the views as you cut through both the Rockies and Sierra Nevada mountain ranges.
Bottom line. The Amtrak Guest Rewards Preferred Mastercard currently has a limited-time offer that can get you roughly $1,000 value in Amtrak train fare, with an $99 annual fee. The potential value is high, but I don’t know if it is too niche to include in my list of Top 10 Best Credit Card Bonus Offers. For you folks that prefer cash or near-cash, you could also get $400 in Amazon or Walmart gift cards with 40,000 points, minus the $99 annual fee.
An anonymous reader quotes a report from TechCrunch: It's only been a day since ChatGPT's new AI image generator went live, and social media feeds are already flooded with AI-generated memes in the style of Studio Ghibli, the cult-favorite Japanese animation studio behind blockbuster films such as "My Neighbor Totoro" and "Spirited Away." In the last 24 hours, we've seen AI-generated images representing Studio Ghibli versions of Elon Musk, "The Lord of the Rings", and President Donald Trump. OpenAI CEO Sam Altman even seems to have made his new profile picture a Studio Ghibli-style image, presumably made with GPT-4o's native image generator. Users seem to be uploading existing images and pictures into ChatGPT and asking the chatbot to re-create it in new styles.
OpenAI's latest update comes on the heels of Google's release of a similar AI image feature in its Gemini Flash model, which also sparked a viral moment earlier in March when people used it to remove watermarks from images. OpenAI's and Google's latest tools make it easier than ever to re-create the styles of copyrighted works -- simply by typing a text prompt. Together, these new AI image features seem to reignite concerns at the core of several lawsuits against generative AI model developers. If these companies are training on copyrighted works, are they violating copyright law?
According to Evan Brown, an intellectual property lawyer at the law firm Neal & McDevitt, products like GPT-4o's native image generator operate in a legal gray area today. Style is not explicitly protected by copyright, according to Brown, meaning OpenAI does not appear to be breaking the law simply by generating images that look like Studio Ghibli movies. However, Brown says it's plausible that OpenAI achieved this likeness by training its model on millions of frames from Ghibli's films. Even if that was the case, several courts are still deciding whether training AI models on copyrighted works falls under fair use protections. "I think this raises the same question that we've been asking ourselves for a couple years now," said Brown in an interview. "What are the copyright infringement implications of going out, crawling the web, and copying into these databases?"

sciencehabit quotes a report from Science.org: Whales sing, orcas squeal, and sea turtles croak. But sharks are more the strong, silent type. Now, researchers report the first evidence that sharks make sounds, too, described today in Royal Society Open Science. The animals may be making the sounds -- a series of clicking noises -- by snapping their flat rows of teeth, which are blunt for crushing prey. The sharks can hear mostly low-frequency noise, and the clicks they emit are higher pitched, which suggests they are not for communicating with other rigs. It's possible they are a defensive tactic. Marine mammals that eat rigs, such as leopard seals, can hear in the frequency range of the rig clicks, but the researchers question whether a few clicks would deter an attack. The sounds might be part of their response to being startled, the team says.

JPMorgan Chase used a quantum computer from Honeywell's Quantinuum to generate and mathematically certify truly random numbers -- an advancement that could significantly enhance encryption, security, and financial applications. The breakthrough was validated with help from U.S. national laboratories and has been published in the journal Nature. From a report: Between May 2023 and May 2024, cryptographers at JPMorgan wrote an algorithm for a quantum computer to generate random numbers, which they ran on Quantinuum's machine. The US Department of Energy's supercomputers were then used to test whether the output was truly random. "It's a breakthrough result," project lead and Head of Global Technology Applied Research at JPMorgan, Marco Pistoia told Bloomberg in an interview. "The next step will be to understand where we can apply it."
Applications could ultimately include more energy-efficient cryptocurrency, online gambling, and any other activity hinging on complete randomness, such as deciding which precincts to audit in elections.

According to the Financial Times, Fidelity Investments is in advanced stages of developing its own stablecoin. Binance reports: The Boston-based financial services giant plans for the token to serve as a form of digital cash, according to the report, which cites two people close to the matter. The token would form part of company's strategy to enter the tokenized government bonds market. Stablecoins are a cryptocurrency whose value is pegged to a real-world asset such as the U.S. dollar or gold. They provide a convenient way for crypto traders to preserve their fiat value without having to cash out of the market.
The news emerges just days after Fidelity filed paperwork to register a blockchain-based version of its U.S. dollar money market fund. The company seeks to register an "OnChain" share class of its Treasury Digital Fund (FYHXX), which holds cash and U.S. Treasury securities and is available only to Fidelity's hedge fund and institutional clients. A Fidelity stablecoin could fill the role of cash in this fund. The report comes a day after World Liberty Financial, a crypto venture backed by Donald Trump and his family, launched a U.S. dollar-pegged stablecoin called USD1.

An anonymous reader quotes a report from ZDNet, written by Steven Vaughan-Nichols: Despite the minor delay, Linux 6.14 arrives packed with cutting-edge features and improvements to power upcoming Linux distributions, such as the forthcoming Ubuntu 25.04 and Fedora 42. The big news for desktop users is the improved NTSYNC driver, especially those who like to play Windows games or run Windows programs on Linux. This driver is designed to emulate Windows NT synchronization primitives. What that feature means for you and me is that it will significantly improve the performance of Windows programs running on Wine and Steam Play. [...] Gamers always want the best possible graphics performance, so they'll also be happy to see that Linux now supports recently launched AMD RDNA 4 graphics cards. This approach includes support for the AMD Radeon RX 9070 XT and RX 9070 graphics cards. Combine this support with the recently improved open-source RADV driver and AMD gamers should see the best speed yet on their gaming rigs.
Of course, the release is not just for gamers. Linux 6.14 also includes several AMD and Intel processor enhancements. These boosts focus on power management, thermal control, and compute performance optimizations. These updates are expected to improve overall system efficiency and performance. This release also comes with the AMDXDNA driver, which provides official support for AMD's neural processing units based on the XDNA architecture. This integration enables efficient execution of AI workloads, such as convolutional neural networks and large language models, directly on supported AMD hardware. While Rust has faced some difficulties in recent months in Linux, more Rust programming language abstractions have been integrated into the kernel, laying the groundwork for future drivers written in Rust. [...] Besides drivers, Miguel Ojeda, Rust for Linux's lead developer, said recently that the introduction of the macro for smart pointers with Rust 1.84: derive(CoercePointee) is an "important milestone on the way to building a kernel that only uses stable Rust functions." This approach will also make integrating C and Rust code easier. We're getting much closer to Rust being grafted into Linux's tree.
In addition, Linux 6.14 supports Qualcomm's latest Snapdragon 8 Elite mobile processor, enhancing performance and stability for devices powered by this chipset. That support means you can expect to see much faster Android-based smartphones later this year. This release includes a patch for the so-called GhostWrite vulnerability, which can be used to root some RISC-V processors. This fix will block such attacks. Additionally, Linux 6.14 includes improvements for the copy-on-write Btrfs file system/logical volume manager. These primarily read-balancing methods offer flexibility for different RAID hardware configurations and workloads. Additionally, support for uncached buffered I/O optimizes memory usage on systems with fast storage devices. Linux 6.14 is available for download here.
