From Space Triumphs to Medical Milestones: Biggest Science News (Aug 28-29, 2025)

Key Facts

• Cosmic Firsts: Astronomers have captured the first-ever direct image of a planet being born – spotting infant gas giant WISPIT 2b forming inside the dusty rings of a young star – while the James Webb telescope revealed the Butterfly Nebula glittering with unexpected “gemstone-like” cosmic crystals and complex carbon molecules ts2.tech ts2.tech. These discoveries offer unprecedented insight into how planets and life’s ingredients take shape in space.
• Rocket Comeback: SpaceX’s Starship finally broke its streak of explosions with a landmark test flight. On Aug 26, the 403-foot rocket lifted off successfully, deployed satellites via a novel “Pez dispenser” system, and survived its fiery reentry – a pivotal success hailed by NASA as paving the way for future Moon landings ts2.tech ts2.tech. Acting NASA chief Sean Duffy applauded that “Flight 10’s success paves the way for the Starship [lander] that will bring American astronauts back to the Moon on Artemis III” ts2.tech.
• New Human Ancestors: Fossils unearthed in East Africa revealed a previously unknown species of early human (Australopithecus), showing that multiple human-like species coexisted ~2.7 million years ago ts2.tech. Meanwhile in Georgia, archaeologists found a 1.8 million-year-old human jawbone – one of the oldest human fossils outside Africa – underscoring that our ancestors spread into Eurasia by that time ts2.tech ts2.tech. These finds rewrite the story of human evolution into a bushy family tree rather than a straight line.
• Medical Milestones: In a world-first surgery, surgeons in China transplanted a pig’s lung into a human (a brain-dead 39-year-old man); astonishingly, the organ worked for 9 days ts2.tech. Experts call the xenotransplant a promising step toward easing organ shortages – though caution we’re “not on the dawn” of routine pig-organ use yet ts2.tech. And in public health, U.S. researchers argue that routine adult tetanus/diphtheria booster shots may be unnecessary given strong childhood vaccination – noting an American is “10 to 1,000 times more likely to be struck by lightning” than to get those diseases ts2.tech ts2.tech.
• Climate & Environment: A blockbuster study warns tropical deforestation is causing ~28,000 extra heat-related deaths per year, over 20 years – totaling more than 500,000 deaths ts2.tech. Researchers bluntly conclude that “deforestation kills,” since clearing forests in the Amazon, Congo, and southeast Asia locally drives up temperatures by 2–3 °C ts2.tech. In better news, an analysis finds that 1990s climate models accurately predicted sea-level rise by 2025 (projecting ~8 cm vs ~9 cm observed) ts2.tech – boosting confidence that we “have understood for decades what is really happening” with climate change ts2.tech ts2.tech. And in a twist, biologists discovered “plastivore” waxworm caterpillars can devour a plastic shopping bag in ~24 hours and metabolize the plastic into body fat ts2.tech. However, on a plastic-only diet “they do not survive more than a few days,” so scientists are now feeding the waxworms sugar supplements to keep them alive while they munch waste ts2.tech ts2.tech.
• Physics Breakthroughs: A Caltech team achieved a 30× leap in quantum memory – converting qubit data into high-frequency sound waves to store quantum information far longer ts2.tech. Their hybrid superconducting system extended qubit lifetimes by a factor of 30, addressing a key hurdle for practical quantum computers ts2.tech. And in photonics, researchers crafted exotic “spacetime crystals” from knotted laser light (hopfions), arranging light’s polarization into repeating 3D patterns. This proof-of-concept “opens a path to… robust topological information processing” using light – potentially enabling ultra-secure communications and new optical computing methods ts2.tech ts2.tech.
• AI in Healthcare: The UK’s National Health Service has begun trials of an AI system (DERM) to detect skin cancer from smartphone photos as accurately as dermatologists ts2.tech. Early results show the algorithm can safely rule out cancer with 99.8% accuracy, potentially fast-tracking benign cases. However, experts urge caution: the tool was trained mostly on light-skinned patients, so there’s little data on performance in darker skin tones, and it currently lacks any doctor oversight ts2.tech. Regulators have only approved it for use with safeguards (for example, requiring a specialist review in certain higher-risk cases) nature.com nature.com. The hope is that such AI triage could catch cancers earlier and ease overloaded clinics – but real-world validation is ongoing to ensure it improves outcomes without missing deadly cases ts2.tech.

Space and Astronomy

A Planet Is Born: In a feat long thought nearly impossible, astronomers have directly imaged a planet in the act of forming. Using the ESO’s Very Large Telescope in Chile, a team snapped a clear picture of WISPIT 2b, a gas giant about five times Jupiter’s mass, carving out a gap in the multi-ringed disk of a young Sun-like star ts2.tech ts2.tech. The baby planet glows red-hot as it accumulates gas. “Discovering this planet… was an amazing experience — we were incredibly lucky,” said Dr. Richelle van Capelleveen of Leiden Observatory, a co-leader of the discovery ts2.tech. WISPIT 2b’s host star is only ~5 million years old and part of an unexpected stellar group, making its spectacular concentric disk a surprise find ts2.tech. Once the team spotted the disk’s rings, they quickly followed up and found the planet nestled in one of the gaps, confirming the planet’s orbit around the star ts2.tech. This marks the first unambiguous image of a protoplanet in a multi-ring disk – offering a unique “lab” for studying how newborn planets interact with their birth disks. As one co-author put it, “WISPIT 2b… is a remarkable discovery” that will serve as a benchmark for planet-formation theories ts2.tech. It’s only the second time any forming exoplanet has been imaged at such an early stage, and scientists predict this system will be a touchstone for years to come in unraveling how diverse planetary systems arise.

Webb’s Cosmic Chemistry Surprise: Not to be outdone, the James Webb Space Telescope (JWST) delivered a jaw-dropping view of the Butterfly Nebula (NGC 6302) – a brilliant twin-lobed cloud formed by a dying Sun-like star. Webb’s infrared eyes pierced the nebula’s core and found a treasure trove of unexpected chemistry ts2.tech. Amid the nebula’s fiery orange “wings,” researchers detected sparkling crystalline grains and complex carbon molecules, described as “gemstone-like” dust that wasn’t supposed to be there ts2.tech. These tiny crystals (silicates similar to quartz) and polycyclic aromatic hydrocarbons (carbon ring molecules) suggest that even a chaotic stellar wreckage can forge the ingredients of planets and life sciencedaily.com sciencedaily.com. “For years, scientists have debated how cosmic dust forms in space. But now, with the help of [JWST], we may finally have a clearer picture,” said Dr. Mikako Matsuura of Cardiff University sciencedaily.com. Webb saw that some dust in the Butterfly Nebula has ordered, crystalline structure – essentially cosmic gemstones – rather than amorphous soot sciencedaily.com. “We were able to see both cool gemstones formed in calm, long-lasting zones and fiery grime created in violent, fast-moving parts of space, all within a single object,” Matsuura noted sciencedaily.com. The discovery is forcing astronomers to rethink nebula chemistry, since carbon-rich organic compounds weren’t expected in this oxygen-rich nebula ts2.tech. Researchers suspect these space crystals condensed in cooler pockets around the central star, which is one of the hottest known (at 220,000 K) sciencedaily.com. Ultimately, such findings hint at how the raw materials of rocky planets – silicates and carbon compounds – are forged and dispersed by dying stars. As the team wrote, “The birth of spacetime hopfion crystals… opens a path to robust topological information processing” across many light-based technologies sciencedaily.com (demonstrating that even nature’s cosmic artwork can seed practical insights). (Note: The preceding quote refers to the hopfion study in photonics; see Physics section.)

Starship Sticks the Landing: In spaceflight news, SpaceX’s Starship – the world’s most powerful rocket – finally achieved a fully successful test mission after a series of dramatic failures. On August 26, Starship’s 10th test flight launched from Texas and reached orbit, marking huge milestones for Elon Musk’s company ts2.tech. For the first time, the Starship’s upper stage deployed payloads in space: it released eight dummy Starlink satellites using an innovative carousel-like “Pez dispenser” mechanism ts2.tech. About an hour later, the Starship vehicle survived a blazing reentry through Earth’s atmosphere, demonstrating that its heat shield upgrades could protect it during the fiery plunge ts2.tech. The mission ended with Starship performing a controlled engine-guided belly flop into the ocean near Australia (the booster was ditched into the Gulf of Mexico earlier) reuters.com reuters.com. This outcome marked a turning point after several high-profile explosions earlier in the program. Acting NASA Administrator Sean Duffy cheered the progress on X (Twitter), saying “Flight 10’s success paves the way for the Starship Human Landing System that will bring American astronauts back to the Moon on Artemis III.” ts2.tech. NASA is counting on Starship to land the next astronauts on the Moon in 2027, and SpaceX ultimately envisions using it for Mars trips as well ts2.tech. Significant work remains – the giant rocket still needs to master in-orbit refueling and nail precise landings back on Earth and the Moon – but this test gave a major confidence boost that Starship’s “build-test-fly” approach is paying off reuters.com reuters.com. Space industry analysts noted that this mission validated key systems (like the heat shield and payload deployment); it “turned the page on a streak of failures” and will likely accelerate Starship’s development reuters.com reuters.com. For SpaceX, which hopes to use Starship for deploying the bulk of its next-gen Starlink satellites, the success also has big business implications reuters.com reuters.com.

Nigeria’s Egusi Soup… in Space?: In an inspiring cross-cultural twist, a staple of West African cuisine hitched a ride to orbit this month. Nigeria sent egusi melon seeds to the International Space Station (ISS) as part of an experiment in microgravity agriculture ts2.tech. Egusi melon seeds – famous for thickening delicious Nigerian soups – spent seven days aboard the ISS in a NASA capsule before returning to Earth for study ts2.tech. “Everybody in Nigeria eats egusi, and even other people in West Africa and the diaspora, so this mission is something they could identify with,” said Temidayo Oniosun, the Nigerian researcher who championed the project ts2.tech. Beyond the cultural symbolism, scientists will analyze whether exposure to space altered the seeds’ genetics, growth, or nutritional value ts2.tech. The goal is to see if future astronauts could grow familiar indigenous crops – not just lettuce and potatoes – on lunar or Martian bases. Oniosun explained that in coming decades, when humans live on the Moon or Mars, “foods that are native to Africa would be part of that” vision reuters.com. For Nigerians, seeing a beloved local seed venture to space has been a source of pride. The egusi experiment, alongside other seeds from around the world, exemplifies how space science can celebrate global heritage while exploring new frontiers ts2.tech. If successful, it could pave the way for more diverse crops in space farms – ensuring that even off-world settlers might one day enjoy a taste of home.

Health and Medicine

Pig-to-Human Lung Transplant: A historic xenotransplantation breakthrough made headlines this week, blurring the line between species in organ donation. Researchers in China announced they had transplanted a pig’s lung into a human for the first time – specifically into a 39-year-old man who was brain-dead but kept alive on support – and remarkably, the pig lung functioned for 216 hours (9 days) inside the man’s body ts2.tech ts2.tech. The pig donor had been genetically modified with six key gene edits to reduce rejection ts2.tech. In the transplant, the usual immediate immune onslaught (hyperacute rejection) that destroys pig organs within minutes was successfully averted ts2.tech. However, despite heavy immunosuppressant drugs, the patient’s immune system gradually began attacking the pig lung over the course of days, causing increasing damage by day 9 ts2.tech. The experiment (published in Nature Medicine) was a carefully supervised proof-of-concept, since the recipient was already brain-dead. Experts not involved in the study are excited but urge caution. Dr. Justin Chan, a NYU transplant surgeon, called the pig-lung trial “exciting and promising” yet a “qualified success,” noting it’s just one case and that the pig lung alone could not have kept the patient alive (the man’s own lung remained in place to sustain him) ts2.tech. Other specialists agreed it’s a meaningful step forward, but not a revolution just yet. “We are not on the dawn of an era of lung xenotransplantation… much more work is required,” stressed Prof. Andrew Fisher of Newcastle University ts2.tech. Still, the fact that a pig lung survived over a week in a human chest – without immediate rejection – is being hailed as a remarkable milestone ts2.tech. It demonstrates real progress toward one day using animal organs to ease human organ shortages (only ~10% of needed transplants are met today) theguardian.com theguardian.com. Researchers will now study the recovered pig lung tissue to understand the immune damage and refine techniques. With pig kidney and heart transplants also advancing, this lung experiment adds to the cautious optimism that genetically engineered pig organs might eventually become a lifesaving bridge for patients on waitlists – though clinical use in living patients is still likely years away, pending further trials.

Rethinking Adult Booster Shots: On the public health front, scientists are challenging a long-held vaccine habit: the routine tetanus and diphtheria (Td) booster shots that adults in many countries receive every 10 years. A new review by Oregon Health & Science University researchers suggests the U.S. could safely drop most Td boosters for adults, because childhood vaccinations already provide extremely long-lasting protection ts2.tech ts2.tech. Many countries (like the UK, WHO members, etc.) do not recommend regular adult tetanus/diphtheria boosters – and they see no more cases of those diseases than countries that do ts2.tech ts2.tech. Prior studies show immunity from the initial childhood shots lasts at least 30 years, likely far longer ts2.tech. Lead author Dr. Mark Slifka argues that as long as childhood vaccination rates remain high, routine adult boosters add little benefit and may be unnecessary (saving an estimated $1 billion in healthcare costs each year in the U.S.) ts2.tech ts2.tech. “By maintaining high childhood vaccination coverage, we not only protect kids, but we may actually be able to reduce adult booster vaccinations,” Dr. Slifka noted ts2.tech. Thanks to widespread kids’ immunizations, tetanus and diphtheria have become vanishingly rare: in the U.S., “you’re 10 to 1,000 times more likely to be struck by lightning” than to contract those diseases, Slifka pointed out ts2.tech. The review stopped short of saying adult boosters are harmful – and it still recommends getting a tetanus shot if you have a dirty wound and haven’t had one in many years ts2.tech. But it strongly questions the “every 10 years” booster tradition, suggesting it’s driven more by habit than by evidence ts2.tech. If U.S. health authorities eventually adopt this guidance, adults might skip many needle jabs over their lifetime. The key caveat is that childhood DTaP vaccination must remain near-universal – that foundational immunity is what makes skipping boosters safe ts2.tech. The analysis adds to a growing conversation about tailoring vaccine schedules to current science. It’s a reminder that some medical practices persist simply because “we’ve always done it” – until data like this prompt a rethink.

Climate and Environment

“Deforestation Kills”: Two sobering climate studies put hard numbers on the human toll of environmental change. In one, published in Nature Climate Change, researchers quantified how many people local deforestation-driven warming has killed. The answer is staggering: over 500,000 additional heat-related deaths in the past 20 years due to tropical deforestation theguardian.com theguardian.com. Clearing forests in the Amazon, Central Africa, and Southeast Asia removes shade, reduces rainfall, and increases fires – driving up local temperatures by 2–3 °C on top of global warming theguardian.com theguardian.com. The team found that from 2001 to 2020, this extra heat led to about 28,300 excess deaths per year across deforested tropical regions theguardian.com. Over half of those deaths were in South and Southeast Asia (where large populations overlap heavily deforested areas), a third were in Africa, and the rest in Latin America theguardian.com. One co-author, Prof. Dominick Spracklen of Leeds, didn’t mince words about the takeaway: “deforestation kills” theguardian.com. “Many people will be shocked,” Spracklen said, because when we talk about cutting down rainforests, we usually focus on biodiversity loss or carbon emissions – not immediate human lives lost theguardian.com. But the study reveals a dire public health impact: by literally making local climates deadly, deforestation is directly killing people in those regions. The authors urge that protecting and replanting tropical forests isn’t just about saving distant species or slowing global CO₂ rise – it’s about saving human lives here and now ts2.tech theguardian.com. The findings add new urgency to forest conservation as a life-saving climate adaptation. If tropical countries restore forests, they could reduce heat extremes and prevent tens of thousands of deaths annually in their most vulnerable communities.

Old Models Get it Right: In more encouraging news, climate scientists got a validation of their predictive abilities. A Tulane University-led analysis compared the 1990s projections of sea-level rise against what actually happened 30 years later – and found the old predictions were spot on. Back in 1996, the IPCC’s mid-range models forecast roughly 8 cm of global sea-level rise by 2025; satellites have now measured about 9 cm – an almost exact match scitechdaily.com scitechdaily.com. “We were quite amazed how good those early projections were, especially given how crude the models were back then,” said lead author Prof. Torbjörn Törnqvist scitechdaily.com. The 1990s models did underestimate one thing: the amount of sea-level rise coming from polar ice melt. They projected less than 3 cm from melting ice sheets, but in reality about ~5 cm came from ice melt as Greenland and Antarctica’s contribution ramped up scitechdaily.com. Still, other factors (like thermal expansion of warming oceans) were forecasted well enough that the total sea-level rise landed within a centimeter of reality scitechdaily.com. Törnqvist pointed to this as powerful evidence against climate skeptics: “For anyone who questions the role of humans in changing our climate, here is some of the best proof… we have understood for decades what is really happening.” scitechdaily.com In other words, scientists in the ’90s, using far simpler models, correctly anticipated the trajectory of planetary change. That success boosts confidence that today’s far more sophisticated models are also largely on the right track about future warming and sea-level trends scitechdaily.com scitechdaily.com. The study’s authors note that it’s now crucial to fine-tune regional forecasts of sea-level rise (since local effects vary) and to continue long-term satellite monitoring scitechdaily.com scitechdaily.com. But the bottom line is heartening: despite uncertainties, climate science has reliably predicted major changes – meaning we should heed current projections of accelerating sea rise in coming decades, and prepare accordingly.

Waxworms vs. Plastic: Amid dire climate news, scientists also unveiled a potential crawling solution to our plastic pollution crisis. New research presented at a biology conference showed that the larvae of wax moths – commonly known as waxworms – can devour and metabolize plastic at astonishing rates ts2.tech. About 2,000 of these caterpillars can chew through a standard polyethylene shopping bag in roughly 24 hours, digesting the plastic and converting it into ethylene glycol (antifreeze) and other compounds that end up stored as fat in the worm’s body ts2.tech ts2.tech. In effect, the worms treat plastic as food and integrate it into their biomass ts2.tech. This is remarkable because polyethylene is one of the most stubborn, non-biodegradable plastics (it’s the kind of plastic in single-use bags and packaging). The waxworms’ ability to break the polymer’s chemical bonds in days instead of decades hints at a natural toolkit for degrading waste ts2.tech ts2.tech. However, there’s a big catch: a 100% plastic diet is fatal to the caterpillars. “They do not survive more than a few days on a plastic-only diet and they lose considerable mass,” said Dr. Bryan Cassone of Brandon University, who led the study ts2.tech. Essentially, the worms starve or get poisoned if they don’t get other nutrients. To solve this, Cassone’s team is experimenting with feeding the waxworms a supplemental diet (like adding sugar or bran) alongside plastic, and early results show the worms stay healthier and can eat more plastic over time ts2.tech sciencedaily.com. The researchers are optimistic that they can either bioengineer the worms’ gut microbes or isolate the key enzymes to create an efficient plastic digestion system without needing millions of live caterpillars ts2.tech. One vision is to mass-rear waxworms fed with a mix of plastic and regular food, so the worms act as tiny recycling plants – with an added bonus that the worm biomass (now full of upcycled fat) could be used as a high-protein feed for fish farms ts2.tech sciencedaily.com. Another approach is to take the enzymes or genes that make this digestion possible and deploy them in industrial reactors or genetically modified bacteria ts2.tech. While it’s early days, this work provides a rare ray of hope in tackling plastic waste. It suggests that evolution, which produced waxworms likely capable of eating beeswax in hives (a chemically somewhat similar substance), might be repurposed to help us break down polyethylene. The idea of “plastivore” insects chomping our trash may sound like science fiction, but it could become one piece of a larger solution to rid the planet of plastic buildup – ideally before more of it ends up in oceans and our own food chain ts2.tech.

Biology and Paleontology

A Tangled Human Family Tree: This week brought stunning discoveries about our ancient human relatives. In Ethiopia’s Ledi-Geraru region – badlands already famous for early human fossils – scientists uncovered remains of a previously unknown hominin species that lived around 2.7 million years ago ts2.tech ts2.tech. The team found 13 fossil teeth that don’t match any known species, but they were buried in the same deposits (dated ~2.6–2.8 Ma) as the earliest fossils of our own genus Homo (including a 2.8 Ma jaw found earlier) ts2.tech ts2.tech. This implies that around the dawn of Homo, there was another kind of Australopithecus (the group of “ape-men” that preceded Homo) living in East Africa at the same time. “We used to think of human evolution as fairly linear, with a steady march from an ape-like ancestor to modern Homo sapiens. Instead, humans have branched out multiple times into different niches,” said Dr. Brian Villmoare of UNLV, lead author on the study ts2.tech. The coexistence of two very different hominins ~2.7 million years ago means the old straight-line “missing link” view is oversimplified ts2.tech. Nature experimented with multiple versions of early humans in parallel – a pattern of a bushy family tree with dead-ends and side branches, which is common in evolution, now clearly applies to our own origins as well ts2.tech. The newly found Australopithecus hasn’t been formally named yet, pending more fossils, but its teeth show it was distinct from Lucy’s species (Australopithecus afarensis) and likely had a different diet or lifestyle ts2.tech ts2.tech. Meanwhile, early Homo was also present in the same area. This means when the first primitive humans were emerging, at least one Australopith lineage was still around – they may have even interacted or competed for resources. The discovery cements that the transition from Australopithecus to Homo was messy and multi-branched, not a single anagenetic progression ts2.tech ts2.tech. As Villmoare put it, “the earliest Homo were not alone.” ts2.tech Each new fossil from this pivotal time is like a puzzle piece showing that our ancestors’ story featured diversity and evolutionary trial-and-error, rather than one preordained path to us.

Pioneers Out of Africa: Heading north, another team unearthed a treasure from one of the first human forays into Eurasia. In Orozmani, a site in the Caucasus hills of Georgia, archaeologists discovered an ancient lower jawbone about 1.8 million years old ts2.tech. The single jaw (with teeth intact) likely belonged to a species of early human such as Homo erectus (or a closely related population) – the very kind that first expanded out of Africa. Orozmani is just 20 km from Dmanisi, the famous Georgian site where several skulls of Homo erectus (sometimes called Homo georgicus for these specimens) were found, also ~1.8 Ma in age ts2.tech. This establishes the area as one of the earliest known habitations of humans outside Africa. The new jaw was found alongside stone tools and animal bones, painting a vivid picture: these hominins were butchering animals and thriving in what was once a savanna-like environment teeming with prehistoric fauna ts2.tech ts2.tech. Fossils of saber-toothed cats, mastodons, deer, wolves, and even giraffes turned up in the same dig ts2.tech. Prof. Giorgi Bidzinashvili of Ilia State University, who leads the Georgian team, said studying the remains “will allow us to determine the lifestyle of the first colonisers of Eurasia,” adding “We think Orozmani can give us big information about humankind.” ts2.tech. The fact that humans were in the Caucasus by 1.8 Ma suggests that Homo erectus (or a similar species) migrated from Africa almost as soon as they evolved, taking advantage of favorable climates and rich ecosystems. It also means Europe and Asia have hosted humans (broadly defined) for nearly two million years. Each new find at places like Orozmani helps us understand how these early adventurers survived – what they ate, how they hunted or scavenged (cut marks on animal bones are being analyzed), and how they adapted to non-African environments. As one archaeologist quipped, at Orozmani you only have to dig a few centimeters before “there’s a good chance you’re going to find something” exciting ts2.tech. Ongoing excavations will likely reveal more fossils and artifacts, further illuminating the story of the first Europeans (or Asians, depending on perspective). The enduring significance is that Georgia’s fossil sites show a successful early human settlement far from our African cradle, highlighting the incredible adaptability and wanderlust of our genus.

Spiky “Dragon” of the Jurassic: In paleontology news, an eye-popping new dinosaur from North Africa has rewritten the record books for armored dinosaurs. Meet Spicomellus afer, an armor-plated herbivore from the Middle Jurassic (~165–168 million years ago) of Morocco, now formally described as the world’s oldest ankylosaur ts2.tech ts2.tech. Ankylosaurs – the tank-like, club-tailed dinosaurs – were previously known mostly from the Cretaceous period and especially from the northern hemisphere. Spicomellus changes that: it shows ankylosaurs existed much earlier and in Africa (part of ancient Gondwana) ts2.tech. What really floored scientists was Spicomellus’s bizarre armor. It was “lavishly adorned with spikes” – including some spikes over a meter long – arranged in a pattern unlike any other known dinosaur ts2.tech ts2.tech. Initially, when isolated bones were found, they were so weird that researchers thought they might be fakes or belong to two different species. But as more of the skeleton was uncovered, it became clear this was a single animal with truly unique anatomy ts2.tech. Spicomellus had spikes and bony plates fused to its ribs (something never seen before) and large fused spines forming a “collar” around its neck sci.news sci.news. One spine was 87 cm long as a fossil – meaning it was likely even longer covered in keratin sheath in life sci.news. In short, this dinosaur was a porcupine-tank hybrid by appearance. University of Birmingham paleontologist Prof. Richard Butler said that seeing the fossils for the first time was “spine-tingling,” and that “we just couldn’t believe how weird it was… unlike any other animal we know of, alive or extinct.” sci.news. Fellow researcher Prof. Susannah Maidment added, “To find such elaborate armor in an early ankylosaur changes our understanding of how these dinosaurs evolved” – it suggests armor started out as display structures (for mating or intimidation) rather than purely for defense sci.news sci.news. Indeed, later ankylosaurs in the Cretaceous had more utilitarian armor (heavy plating and tail clubs to fend off big predators) sci.news sci.news. Spicomellus, living in a time and place with fewer giant predators, appears to have gone armor-crazy for style points – perhaps using its array of spines to attract mates or compete with rivals, as the researchers propose sci.news. Besides being the first ankylosaur found in Africa, Spicomellus pushes the origin of the ankylosaur lineage back about 20 million years earlier than thought ts2.tech ts2.tech. It underscores that the lineage of armored dinosaurs had already split off and spread across Pangaea by the mid-Jurassic, evolving funky traits in isolation. Paleontologists are thrilled by the find – it’s been nicknamed the “weirdest armored dinosaur” yet ts2.tech – and it hints that Africa has many more dinosaur surprises in store. As Moroccan paleontologist Driss Ouarhache noted, “We’ve never seen dinosaurs like this before, and there’s still a lot more this region has to offer.” sci.news The discovery, beyond its scientific import, also helps spark public imagination, proving that even in 2025 we’re still uncovering fantastical new monsters from deep time.

Technology and AI

AI Dermatologist in the Clinic: In technology news, artificial intelligence is making strides in healthcare – with a high-profile pilot in the UK aiming to speed up cancer diagnoses. The NHS has begun testing an AI dermatology system called DERM that can analyze photos of skin lesions and help flag potential skin cancers ts2.tech ts2.tech. At several hospitals in England, general practitioners are using a smartphone with a special dermatoscope attachment to photograph patients’ suspicious moles or skin growths ts2.tech. The images upload to DERM’s cloud, where a machine-learning algorithm (developed by London-based firm Skin Analytics) evaluates each lesion for signs of malignancy ts2.tech. Essentially, the AI acts as a triage tool – it decides which cases look benign (safe to monitor or reassure the patient) and which look concerning enough to need urgent review by a dermatologist ts2.tech. The goal is twofold: catch skin cancers like melanoma earlier, and reduce unnecessary referrals of harmless lesions to overloaded specialists ts2.tech. In early trials, DERM’s performance has been impressive on paper. In fact, the AI recently became the first-ever autonomous AI medical device officially recommended by UK regulators for use in healthcare pharmatimes.com pharmatimes.com. It has scanned over 165,000 patient images with a reported ability to detect 97% of skin cancers, and a negative predictive value of 99.8% for melanoma (meaning if DERM says “no cancer,” there’s a 99.8% chance it’s correct) pharmatimes.com. That’s on par with, or even slightly better than, the accuracy of human dermatologists in catching dangerous lesions pharmatimes.com. By autonomously clearing about 30–40% of low-risk cases, such a system could free up doctors’ time to focus on patients who truly need specialist care pharmatimes.com pharmatimes.com. However, experts caution that real-world use requires care. One concern is bias in the training data: the AI learned from a dataset largely consisting of lighter-skinned individuals, so there’s scant data on how well it identifies cancers on darker skin nature.com nature.com. Melanomas in Black and brown patients can look different and often appear on different parts of the body (like under nails or on soles) that algorithms might not generalize to if not trained properly. There’s a risk the AI could miss malignancies in these groups – a serious equity issue. Another concern is the lack of a human in the loop for “low risk” assessments ts2.tech. If the AI were to wrongly label a melanoma as benign and no doctor double-checks, that patient might be falsely reassured and delay treatment. Recognizing this, the UK’s health watchdog (NICE) approved DERM for a limited 3-year trial with conditions – for instance, patients with the darkest skin types should still be referred to a dermatologist after AI assessment, and the AI’s decisions will be monitored skin-analytics.com skin-analytics.com. Dermatologists like Dr. Julia Schofield support cautious integration, noting “The NHS is in crisis. This tool…has the potential to reassure patients and avoid unnecessary hospital visits” pharmatimes.com. The hope is that, after gathering more evidence, AI triage systems could become routine assistants – not replacing doctors but augmenting them, catching more cancers early and streamlining care. It’s a compelling example of AI’s promise in medicine, but one that must be backed by robust validation to ensure safety across all patient groups. As Skin Analytics’ CEO Neil Daly said, this marks “the beginning of what AI can do to support patients and overstretched clinicians.” pharmatimes.com If successful, it could open the door for other AI diagnostic tools in healthcare – from scanning X-rays to reading pathology slides – fundamentally transforming how frontline medicine is practiced.

Quantum and Photonic Tech Frontiers: Outside the clinic, the tech world saw advances at the cutting edge of computing and materials. At Caltech, researchers delivered a breakthrough in quantum computing hardware by solving a major problem: how to store fragile quantum information longer. They built a novel device that converts qubit states into high-frequency sound waves (phonons) on a chip, creating a sort of quantum “memory” that preserves the data ~30 times longer than conventional superconducting qubits do sciencedaily.com sciencedaily.com. Prof. Mohammad Mirhosseini, who led the work, explained that in current quantum processors, qubits are great at rapid calculations but can’t hold on to quantum states for long – akin to having super fast RAM but no long-term storage sciencedaily.com sciencedaily.com. The Caltech team’s fix was to interface a qubit with a tiny nanoscale mechanical oscillator – effectively a microscopic tuning fork that vibrates when excited by the qubit’s signal sciencedaily.com sciencedaily.com. When the qubit’s state is transferred into the oscillator (stored as a quantum vibration), it decays far more slowly because acoustic vibrations lose energy much more slowly than electromagnetic signals in a circuit sciencedaily.com sciencedaily.com. “It turns out that these oscillators have a lifetime about 30 times longer than the best superconducting qubits out there,” Mirhosseini said sciencedaily.com. This hybrid approach allowed the team to “put quantum data on pause” and retrieve it later intact – a crucial step toward quantum computers that can handle complex, long computations without data loss sciencedaily.com sciencedaily.com. The memory isn’t perfect yet; the next goal is to speed up the transfer in and out of the acoustic memory (currently a bottleneck) by another factor of 3–10 to make it practical for real circuits ts2.tech sciencedaily.com. But the concept is proven. As one scientist not involved commented, this could be the foundation for scalable quantum RAM. Meanwhile, another international team (from Singapore and Japan) took a leap in photonics by creating what are essentially crystals of light. They devised a way to arrange laser beams into repeating structures called “spacetime hopfion crystals” – basically light waves knotted into loops (hopfions) that repeat periodically in space and time ts2.tech ts2.tech. Hopfions – imagine smoke rings made of light – had been generated before as single shots, but assembling them into a persistent lattice is new. The researchers used two lasers of different colors with carefully tuned polarization and frequency. By making one beam’s frequency a simple ratio of the other, they caused the light field to beat at a fixed interval, stacking a chain of hopfion loops that recur each cycle ts2.tech. Then, they outlined how to extend this into 2D and 3D grids – envision a crystal where each “atom” is a knotted pulse of light, and the pattern repeats in both space and time ts2.tech. These knotted-light crystals are more than a curiosity: the authors say such stable, structured light fields could encode information in entirely new ways. Topologically knotted configurations are very robust to perturbations (you can poke a smoke ring and it stays intact), which is attractive for error-resistant data storage or transmission ts2.tech. By “weaving light into stable knots,” one could pack lots of information (potentially each hopfion’s twist could carry a quantum bit) and send it through optical fiber or free space with minimal losses ts2.tech. The team wrote that “The birth of spacetime hopfion crystals” opens a path to robust topological information processing across optical, terahertz, and microwave domains. ts2.tech In plain terms, this could lead to ultra-secure communication channels or advanced photonic chips where data is encoded in the very shape of light’s polarization loops. While still theoretical and in the lab phase, they even proposed practical ways to generate these crystals, like using tiny antenna arrays or patterned metasurfaces to emit the required light fields ts2.tech. It’s a mind-bending fusion of abstract math (knot theory) and engineering, showing how even light – normally ephemeral – can be harnessed in new states of matter (or “matter-less” matter) to potentially drive the next computing revolution. From quantum acoustics to knotted light, this week’s tech breakthroughs underline the creative ingenuity at the frontiers of science, where solutions to big problems sometimes involve literally changing the wavelength of approach.
