Despite recent test failures, NASA has added SpaceX's Starship to its Launch Services Program contract, allowing it to compete for future science missions once it achieves a successful orbital flight. Florida Today reports: NASA announced the addition Friday to its current launch provider contract with SpaceX, which covers the Falcon 9 and Falcon Heavy. This opens the possibility of Starship flying future NASA science missions -- that is once Starship reaches a successful orbital flight.

"NASA has awarded SpaceX of Starbase, Texas, a modification under the NASA Launch Services (NLS) II contract to add Starship to their existing Falcon 9 and Falcon Heavy launch service offerings," NASA's statement reads. Th announcement is simply an onboarding of Starship as an option, as the contract runs through 2032. However, SpaceX is under pressure to get Starship operational by next year as the company plans not only to send an uncrewed Starship to Mars by late 2026, but the NASA Artemis III moon landing is fast approaching. Should it remain the plan with the current administration, Starship will act as a human lander for NASA's Artemis III crew.

"The NLS II contracts are multiple award, indefinite-delivery/indefinite-quantity, with an ordering period through June 2030 and an overall period of performance through December 2032. The contracts include an on-ramp provision that provides an opportunity annually for new launch service providers to add their launch service on an NLS II contract and compete for future missions and allows existing contractors to introduce launch services not currently on their NLS II contracts," NASA's statement reads.

A new study warns that toxic Martian dust contains fine particles and harmful substances like silica and metals that pose serious health risks to astronauts, making missions to Mars more dangerous than previously thought. The Guardian reports: During Apollo missions to the moon, astronauts suffered from exposure to lunar dust. It clung to spacesuits and seeped into the lunar landers, causing coughing, runny eyes and irritated throats. Studies showed that chronic health effects would result from prolonged exposure. Martian dust isn't as sharp and abrasive as lunar dust, but it does have the same tendency to stick to everything, and the fine particles (about 4% the width of a human hair) can penetrate deep into lungs and enter the bloodstream. Toxic substances in the dust include silica, gypsum and various metals.

"A mission to Mars does not have the luxury of rapid return to Earth for treatment," the researchers write in the journal GeoHealth. And the 40-minute communication delay will limit the usefulness of remote medical support from Earth. Instead, the researchers stress that limiting exposure to dust is essential, requiring air filters, self-cleaning space suits and electrostatic repulsion devices, for example.

New research suggests that Prototaxites, once believed to be a giant fungus, may actually represent an entirely extinct and previously unknown branch of complex life, distinct from fungi, plants, animals, and protists. Live Science reports: The researchers studied the fossilized remains of one Prototaxites species named Prototaxites taiti, found preserved in the Rhynie chert, a sedimentary deposit of exceptionally well-preserved fossils of early land plants and animals in Scotland. This species was much smaller than many other species of Prototaxites, only growing up to a few inches tall, but it is still the largest Prototaxites specimen found in this region. Upon examining the internal structure of the fossilized Prototaxites, the researchers found that its interior was made up of a series of tubes, similar to those within a fungus. But these tubes branched off and reconnected in ways very unlike those seen in modern fungi. "We report that Prototaxites taiti was the largest organism in the Rhynie ecosystem and its anatomy was fundamentally distinct from all known extant or extinct fungi," the researchers wrote in the paper. "We therefore conclude that Prototaxites was not a fungus, and instead propose it is best assigned to a now entirely extinct terrestrial lineage."

True fungi from the same period have also been preserved in the Rhynie chert, enabling the researchers to chemically compare them to Prototaxites. In addition to their unique structural characteristics, the team found that the Prototaxites fossils left completely different chemical signatures to the fungi fossils, indicating that the Prototaxites did not contain chitin, a major building block of fungal cell walls and a hallmark of the fungal kingdom. The Prototaxites fossils instead appeared to contain chemicals similar to lignin, which is found in the wood and bark of plants. "We conclude that the morphology and molecular fingerprint of P. taiti is clearly distinct from that of the fungi and other organism preserved alongside it in the Rhynie chert, and we suggest that it is best considered a member of a previously undescribed, entirely extinct group of eukaryotes," the researchers wrote. The research has been published on the preprint server bioRxiv.

An anonymous reader quotes a report from Ars Technica: Imagine working with special cameras that capture light your eyes can't even see -- ultraviolet rays that cause sunburn, infrared heat signatures that reveal hidden writing, or specific wavelengths that plants use for photosynthesis. Or perhaps using a special camera designed to distinguish the subtle visible differences that make paint colors appear just right under specific lighting. Scientists and engineers do this every day, and they're drowning in the resulting data. A new compression format called Spectral JPEG XL might finally solve this growing problem in scientific visualization and computer graphics. Researchers Alban Fichet and Christoph Peters of Intel Corporation detailed the format in a recent paper published in the Journal of Computer Graphics Techniques (JCGT). It tackles a serious bottleneck for industries working with these specialized images. These spectral files can contain 30, 100, or more data points per pixel, causing file sizes to balloon into multi-gigabyte territory -- making them unwieldy to store and analyze.

[...] The current standard format for storing this kind of data, OpenEXR, wasn't designed with these massive spectral requirements in mind. Even with built-in lossless compression methods like ZIP, the files remain unwieldy for practical work as these methods struggle with the large number of spectral channels. Spectral JPEG XL utilizes a technique used with human-visible images, a math trick called a discrete cosine transform (DCT), to make these massive files smaller. Instead of storing the exact light intensity at every single wavelength (which creates huge files), it transforms this information into a different form. [...]

According to the researchers, the massive file sizes of spectral images have reportedly been a real barrier to adoption in industries that would benefit from their accuracy. Smaller files mean faster transfer times, reduced storage costs, and the ability to work with these images more interactively without specialized hardware. The results reported by the researchers seem impressive -- with their technique, spectral image files shrink by 10 to 60 times compared to standard OpenEXR lossless compression, bringing them down to sizes comparable to regular high-quality photos. They also preserve key OpenEXR features like metadata and high dynamic range support. The report notes that broader adoption "hinges on the continued development and refinement of the software tools that handle JPEG XL encoding and decoding."

Some scientific applications may also see JPEG XL's lossy approach as a drawback. "Some researchers working with spectral data might readily accept the trade-off for the practical benefits of smaller files and faster processing," reports Ars. "Others handling particularly sensitive measurements might need to seek alternative methods of storage."

A breach of legacy Cerner servers at Oracle Health exposed patient data from multiple U.S. hospitals and healthcare organizations, with threat actors using compromised customer credentials to steal the data before it had been migrated to Oracle Cloud. Despite confirming the breach privately, Oracle Health has yet to publicly acknowledge the incident. BleepingComputer reports: Oracle Health, formerly known as Cerner, is a healthcare software-as-a-service (SaaS) company offering Electronic Health Records (EHR) and business operations systems to hospitals and healthcare organizations. After being acquired by Oracle in 2022, Cerner was merged into Oracle Health, with its systems migrated to Oracle Cloud. In a notice sent to impacted customers and seen by BleepingComputer, Oracle Health said it became aware of a breach of legacy Cerner data migration servers on February 20, 2025.

"We are writing to inform you that, on or around February 20, 2025, we became aware of a cybersecurity event involving unauthorized access to some amount of your Cerner data that was on an old legacy server not yet migrated to the Oracle Cloud," reads a notification sent to impacted Oracle Health customers. Oracle says that the threat actor used compromised customer credentials to breach the servers sometime after January 22, 2025, and copied data to a remote server. This stolen data "may" have included patient information from electronic health records. However, multiple sources told BleepingComputer that it was confirmed that patient data was stolen during the attack.

Oracle Health is also telling hospitals that they will not notify patients directly and that it is their responsibility to determine if the stolen data violates HIPAA laws and whether they are required to send notifications. However, the company says they will help identify impacted individuals and provide templates to help with notifications.

An anonymous reader shares a report: New data recently released by the Environmental Protection Agency indicate that more than 158 million people across the U.S. have drinking water contaminated by toxic "forever chemicals," scientifically known as perfluoroalkyl and polyfluoroalkyl substances (PFAS).

"Drinking water is a major source of PFAS exposure. The sheer number of contaminated sites shows that these chemicals are likely present in most of the U.S. water supply," said David Andrews, deputy director of investigations and a senior scientist at the Environmental Working Group (EWG), a nonprofit advocacy organization, in a recent press release.

Stanford University researchers have proposed creating "bodyoids" -- ethically sourced human bodies grown from stem cells without neural components for consciousness or pain sensation -- to revolutionize medical research and address organ shortages. In a new opinion piece published in MIT Technology Review, scientists Carsten T. Charlesworth, Henry T. Greely, and Hiromitsu Nakauchi argue that recent advances in biotechnology make this concept increasingly plausible. The approach would combine pluripotent stem cells, artificial uterus technology, and genetic techniques to inhibit brain development.

The researchers point to persistent shortages of human biological materials as a major bottleneck in medical progress. More than 100,000 patients currently await solid organ transplants in the US alone, while less than 15% of drugs entering clinical trials receive regulatory approval. These lab-grown bodies could potentially generate patient-specific organs that are perfect immunological matches, eliminate the need for lifelong immunosuppression, and provide personalized drug screening models.

A Nature survey has found that three-quarters of responding U.S. scientists are considering leaving the nation following disruptions to science under the Trump administration.

Out of 1,608 respondents, 75.3% said they were contemplating leaving the country. Scientists cited concerns over research funding and the general treatment of science as contributing factors for their reasoning. Europe and Canada were mentioned as potential destinations for those looking for opportunities abroad.

As NASA faces potential budget cuts, China is unveiling an ambitious series of deep space missions -- including Mars sample returns, outer planet exploration, and a future Mars base. While some of China's plans are aspirational, their track record of successful missions lends credibility to their expanding role in space. Ars Technica reports: China created a new entity called the "Deep Space Exploration Laboratory" three years ago to strengthen the country's approach to exploring the Solar System. Located in eastern China, not far from Shanghai, the new laboratory represented a partnership between China's national space agency and a local public college, the University of Science and Technology of China.

Not much is known outside of China about the laboratory, but it has recently revealed some very ambitious plans to explore the Solar System, including the outer planets. This week, as part of a presentation, Chinese officials shared some public dates about future missions. Space journalist Andrew Jones, who tracks China's space program, shared some images with a few details. Among the planned missions are:

- 2028: Tianwen-3 mission to collect samples of Martian soil and rocks and return them to Earth
- 2029: Tianwen-4 mission to explore Jupiter and its moon Callisto
- 2030: Development of a large, ground-based habitat to simulate long-duration human spaceflight
- 2033: Mission to Venus that will return samples of its atmosphere to Earth
- 2038: Establishment of an autonomous Mars research station to study in-situ resource utilization
- 2039: Mission to Triton, Neptune's largest moon, with a subsurface explorer for its ocean

Paul Ginsparg, a physics professor at Cornell University, created arXiv nearly 35 years ago as a digital repository where researchers could share their findings before peer review. Today, the platform hosts more than 2.6 million papers, receives 20,000 new submissions monthly, and serves 5 million active users, Wired writes in a profile of the platform.

"Just when I thought I was out, they pull me back in!" Ginsparg quotes from The Godfather, reflecting his inability to fully hand over the platform despite numerous attempts. If arXiv stopped functioning, scientists worldwide would face immediate disruption. "Everybody in math and physics uses it," says Scott Aaronson, a computer scientist at the University of Texas at Austin. "I scan it every night."

ArXiv revolutionized academic publishing, previously dominated by for-profit giants like Elsevier and Springer, by allowing instant and free access to research. Many significant discoveries, including the "transformers" paper that launched the modern AI boom, first appeared on the platform. Initially a collection of shell scripts on Ginsparg's NeXT machine in 1991, arXiv followed him from Los Alamos National Laboratory to Cornell, where it found an institutional home despite administrative challenges. Recent funding from the Simons Foundation has enabled a hiring spree and long-needed technical updates.

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.

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.

An anonymous reader quotes a report from Gizmodo: Scientists scrutinizing the seafloor beneath a calving iceberg found a remarkable array of living creatures, switching up notions of how the giant chunks of ice affect their immediate environs. The scientists investigated a region of seafloor recently exposed by the calving of a gigantic iceberg -- A-84 -- which is as large as Chicago. The team found a surprisingly vibrant community of critters on the seafloor below where A-84 was once attached to an ice shelf attached to Antarctica.

Without the 197-square-mile (510-square-kilometer) iceberg in the way, the team was able to scrutinize the seafloor at depths of 4,265 feet (1,300 meters) using the remotely operated vehicle (ROV) SuBastian. The team found large corals and sponges supporting other lifeforms, including icefish, giant sea spiders, and octopus. [...] With the icebergs covering the seafloor, organisms below the shelf cannot get nutrients for survival from the surface. The team hypothesized that ocean currents are a critical driver for life beneath the ice sheets. The team also collected data on the larger ice sheet, whose shrinking size spells concern for the animals that live beneath it.
