Hidden “Bad Fat” Threat, Dwarf Planet Discovery, and Warp Drive Breakthrough – Science Roundup (Sept 6–7, 2025)

Key Facts

• New “Dwarf Planet” at Solar System’s Edge: Astronomers discovered a massive trans-Neptunian object (2017 OF201) with a 25,000-year orbit, potentially qualifying as a dwarf planet. This distant world was found well beyond Neptune – challenging the idea that the outer solar system is empty – and its odd trajectory even casts doubt on the proposed “Planet Nine” hypothesis ^[1].
• Hidden Fat Accelerates Heart Aging: A UK study using AI imaging tied visceral fat (invisible fat around organs) to faster aging and inflammation of the heart, even in fit people ^[2]. Researchers found that this “bad” belly fat stiffens the heart, while fat around hips and thighs may actually protect women sciencedaily.com sciencedaily.com. As lead scientist Prof. Declan O’Regan put it, “Our research shows that ‘bad’ fat, hidden deep around the organs, accelerates aging of the heart” ^[3].
• Breast Cancer Drug’s Rare Side Effect Explained: Scientists uncovered how tamoxifen – a life-saving breast cancer drug – can rarely spur uterine tumors. Tamoxifen directly activates a pro-tumor cell growth pathway (PI3K) in uterine tissue, essentially bypassing the genetic mutations usually needed for such cancers ^[4]. “Our results show for the first time that activation of a pro-tumor signaling pathway by a drug is possible,” said Prof. Kirsten Kübler, explaining how this great cancer therapy can paradoxically trigger tumors in another organ ^[5].
• Sleep Aid Shows Alzheimer’s Promise: New research in Nature Neuroscience found that the common insomnia drug lemborexant restored healthy sleep and blunted brain damage in Alzheimer’s-model mice ^[6]. By blocking orexin (a sleep-regulating signal), the drug reduced toxic tau protein buildup and inflammation. “Lemborexant improves sleep and reduces abnormal tau, which appears to be a main driver of the neurological damage,” noted neurologist Dr. David Holtzman, who hopes this approach could complement current Alzheimer’s treatments ^[7].
• Earth’s “Safe Zones” Crossing Dangerous Thresholds: A sweeping study led by the Potsdam Institute (published in One Earth) warns that 60% of global land is now outside safe biosphere limits, with 38% in a high-risk state ^[8]. Human demands on ecosystems – from agriculture to biomass energy – have destabilized natural cycles on every continent. “This first world map of overshoot … is a breakthrough,” said co-author Dr. Johan Rockström, calling for treating biosphere integrity and climate as “one overarching issue” in policy ^[9].
• Carbon Capture Constraints: A new Nature study slashed estimates of how much CO₂ we can stash underground. After ruling out leaky or unsafe storage sites, researchers found global carbon storage capacity is ~10× less than thought ^[10]. That means carbon capture and storage might only cut future warming by ~0.7°C instead of 5+°C. “Carbon storage is often portrayed as a way out of the climate crisis. Our findings make clear that it is a limited tool,” said lead author Dr. Matthew Gidden, underscoring the need to cut emissions faster ^[11].
• Insect Collapse Even in “Pristine” Areas: A 20-year study of a remote Colorado mountain meadow found a 72% drop in flying insect abundance, despite minimal human impact ^[12]. Insects declined ~6.6% per year as summers warmed, implicating climate change in losses even far from farms or cities. “Insects have a unique… position in the biodiversity crisis… they are necessary for ecosystems to function,” said biologist Keith Sockman, who warns that even biodiversity hotspots like mountains are at risk if these trends continue ^{[13] [14]}.
• Warp Drive Theory Edges Closer to Reality: In futuristic physics news, researchers developed a new model for a warp drive that runs on known physics – no “exotic” negative energy needed ^[15]. The team showed it’s mathematically possible to form a warp bubble (distorting spacetime) using conventional energy, albeit likely only for near-light speeds. “We’ve shown that warp drives might not be relegated to science fiction,” said Dr. Jared Fuchs, co-author of the study in Classical and Quantum Gravity ^[16]. While such a device won’t be built anytime soon, it’s a significant step in theoretical physics.
• 200-Year Ice Mystery Solved: German physicists overturned a centuries-old theory about why ice is slippery. It’s not primarily pressure or friction melting the ice, but rather molecular interactions creating a ultra-thin, disordered film on the surface ^[17]. “Neither pressure nor friction plays a significant part… Instead, the orientation of dipoles in the shoe sole interacting with those in the ice” produces a quasi-liquid layer even at –40 °C, explained Prof. Martin Müser ^[18]. This insight revises textbook physics and could improve winter sports science.
• AI-Designed Antibiotics Defeat Superbugs: In a breakthrough for biotechnology, engineers at University of Pennsylvania used generative AI to invent new antibiotic molecules. Their tool “AMP–Diffusion” generated tens of thousands of antimicrobial peptides, two of which successfully treated drug-resistant infections in mice as effectively as standard antibiotics ^{[19] [20]}. “Nature’s dataset is finite; with AI, we can design antibiotics evolution never tried,” said Dr. César de la Fuente, senior author ^[21]. The AI-designed drugs killed MRSA and other superbugs in lab tests without toxic side effects, opening a bold new front in the fight against antibiotic resistance.
• High-Tech Recycling and Clean Energy Innovations: European researchers debuted an AI-guided robotic system that can disassemble used EV batteries safely and efficiently – a key step toward scaling up battery recycling ^[22]. The robot uses machine vision to identify components (even without barcodes) and automates the tedious pack-to-cell breakdown, addressing a major bottleneck in e-waste processing. And in climate tech, chemists unveiled “BAETA,” a novel material upcycled from plastic waste that can soak up CO₂ from air with remarkable efficiency ^[23]. “The beauty of this method is that we solve a problem without creating a new one,” said lead author Margarita Poderyte – turning discarded PET bottles into a carbon-capture sponge ^[24]. Such innovations aim to both cut greenhouse emissions and advance a circular economy.

Space & Astronomy

Distant Dwarf Planet Candidate Discovered: Astronomers announced the discovery of a “hidden world” beyond Neptune – a trans-Neptunian object called 2017 OF201. With an estimated 700 km diameter and an extreme 25,000-year orbit, this object could qualify as a dwarf planet ^{[25] [26]}. It ventures from ~44 AU at closest approach to an aphelion ~1,600 AU (over 0.25 light-years) – far beyond Pluto. Its existence suggests the outer Kuiper Belt isn’t as empty as once thought ^{[27] [28]}. Interestingly, 2017 OF201’s orbit doesn’t line up with the clustering of other distant bodies that hinted at “Planet Nine,” making it an outlier that challenges the Planet Nine hypothesis ^[29]. “The presence of this single object suggests there could be another hundred or so with similar orbits and size; they’re just too far to detect now,” said discoverer Sihao Cheng ^[30]. The find – made by analyzing years of telescope images with new algorithms – underscores how much of our own solar system remains unexplored ^{[31] [32]}.

Total Lunar Eclipse (“Blood Moon”): Skywatchers across Asia, Australia, Africa, and Europe were treated to a total lunar eclipse on September 7, as Earth’s shadow turned the full Harvest Moon a deep coppery red ^[33]. The eclipse (the “Full Corn Moon”) lasted about 84 minutes in totality and was safely visible to the naked eye. Such lunar eclipses occur when the Earth perfectly aligns between the Sun and Moon, and this one was widely observed given that over 80% of humanity was on the nighttime side of Earth during the event ^{[34] [35]}. While not a scientific discovery, the eclipse provided a vivid reminder of celestial mechanics in action – and stunning views for millions of people.

Mars Interior Turbulence Revealed: In planetary science news, NASA’s InSight mission results unveiled a chaotic ancient structure inside Mars. Seismic data show that Mars’ mantle has unexpected heterogeneity, likely remnants of massive impacts and magma upwellings during the planet’s early history ^{[36] [37]}. This challenges the view of Mars as geologically quiet after its formation. The study’s authors describe evidence of “turbulent early history” beneath the Red Planet’s surface, offering clues that Mars experienced vigorous internal convection or even early plate tectonics. Such findings not only rewrite Mars’ geologic history but also help explain puzzling observations – for example, oddities in Mars’ seismic wave readings and gravity field – since these deep mantle variations affect how quakes propagate. (These results were published on September 6, adding a chapter to our understanding of Martian evolution ^[38].)

Health & Medicine

Invisible Fat and Heart Aging: New research delivered a stark health warning: the hidden fat around our organs (visceral fat) can age the heart faster. Scientists analyzed MRI scans of 21,000+ UK adults and found that those with more visceral fat showed stiffer, more inflamed hearts – effectively “older” hearts – compared to their actual age ^{[39] [40]}. This visceral fat, wrapping organs deep in the abdomen, isn’t visible on the outside (even normal-weight people can carry it). “Bad fat, hidden deep around the organs, accelerates aging of the heart,” said Prof. Declan O’Regan, whose team published the findings in European Heart Journal ^[41]. Notably, where fat is stored matters: women with more hip and thigh fat (“pear-shaped” bodies) had slower heart aging, suggesting a protective effect ^[42]. By contrast, the classic “apple shape” belly fat was linked to earlier cardiac aging in men ^[43]. The researchers also found visceral fat raises systemic inflammation, a known driver of aging and cardiovascular disease ^[44]. These results underscore that measuring body mass index (BMI) isn’t enough – fat distribution is key for heart health ^[45]. Even active, fit individuals can harbor risky hidden fat ^[46]. The findings are spurring interest in therapies (like certain diabetes drugs) to specifically target visceral fat and thus potentially slow cardiac aging ^[47].

Tamoxifen’s Cancer Paradox: An international team led by the Berlin Institute of Health solved a decades-old medical mystery: why the breast cancer drug tamoxifen slightly increases risk of uterine cancer. Tamoxifen has saved millions of lives by blocking estrogen in breast tissue, but it was known to very rarely cause secondary endometrial tumors. Researchers discovered tamoxifen can directly activate the PI3K growth pathway in uterine cells, effectively mimicking a cancer-driving mutation ^[48]. Normally, spontaneous uterine tumors often have mutations in the gene PIK3CA (which hyper-activates the PI3K signaling pathway for cell growth). In tamoxifen-linked cases, those mutations were absent – instead, the drug itself turned on the PI3K pathway, “jump-starting” tumor formation without a DNA mutation ^{[49] [50]}. “Our results show for the first time that a drug’s action can substitute for genetic changes in driving a tumor,” explained Prof. Kirsten Kübler, co-author of the study in Nature Genetics ^[51]. Importantly, this side effect remains rare and tamoxifen’s benefits far outweigh the risks for breast cancer patients ^[52]. But understanding this mechanism opens the door to making the therapy even safer – for example, by co-prescribing PI3K inhibitors or closely monitoring at-risk patients. It’s also a wake-up call that other targeted drugs might have similar off-target effects, an area now ripe for further research ^[53].

Sleep Medication as Alzheimer’s Therapy? A promising new avenue emerged for combating Alzheimer’s disease: improving patients’ sleep quality. Researchers at Washington University in St. Louis showed that lemborexant – an FDA-approved insomnia drug – not only helps mice sleep better but also protects their brains against Alzheimer-like damage ^{[54] [55]}. Lemborexant belongs to a class called orexin receptor antagonists (marketed for insomnia as “Dayvigo”). In Alzheimer’s-model mice, the drug restored normal sleep cycles and dramatically reduced the buildup of abnormal tau protein tangles in the brain ^{[56] [57]}. Excess tau is a major driver of neurodegeneration in Alzheimer’s and related dementias. Treated mice had less brain inflammation and neuron loss; notably, their memory center (hippocampus) was about 30–40% larger in volume than in untreated diseased mice ^{[58] [59]}. “We have known that sleep loss is a risk factor for Alzheimer’s,” said senior author Dr. David Holtzman. “In this study, we showed lemborexant improves sleep and reduces abnormal tau, which appears to be a main driver of damage… We’re hopeful this will lead to new therapeutics” ^[60]. Interestingly, a conventional sleep drug (zolpidem/Ambien) did not produce the neuroprotective effect despite promoting sleep ^[61] – indicating that how you induce sleep matters. Lemborexant targets brain regions vulnerable to tau and doesn’t impair motor function, making it an attractive candidate for human trials in Alzheimer’s patients ^{[62] [63]}. While clinical use is still down the road, this study spotlights the intimate link between sleep and brain health, suggesting that tweaking sleep chemistry could slow or prevent neurodegeneration.

Environment & Climate

Planetary Boundaries: 60% of Earth’s Land in the Danger Zone – A comprehensive analysis by an EU-Austrian team (PIK and BOKU University) painted a worrying picture of Earth’s biosphere. They assessed “functional biosphere integrity” – essentially nature’s capacity to sustain life-supporting processes – and found humans have pushed well over half of all land outside the safe zone ^[64]. Even more alarming, 38% of land is now in a “high-risk” state where ecosystems are severely destabilized ^[65]. This study, spanning data from year 1600 to present, shows how centuries of farming, deforestation, and biomass harvest have eroded the planet’s resilience ^{[66] [67]}. Europe, Asia, and North America have the worst disruptions, reflecting long histories of intensive land use ^{[68] [69]}. The research updates the Planetary Boundaries framework – confirming that we are well beyond safe limits for biosphere alteration. Co-author Dr. Johan Rockström called the world map of biosphere overshoot a “scientific breakthrough” and a wake-up call for policymakers ^[70]. “Governments must treat [biosphere integrity and climate] as a single overarching issue: comprehensive biosphere protection together with strong climate action,” Rockström urged ^[71]. In practical terms, that means reining in land clearing and biomass extraction, and investing in restoration, so that natural systems (forests, wetlands, etc.) can continue regulating carbon, water, and nutrient cycles. The study offers an impetus ahead of upcoming global climate and biodiversity summits: we need to address ecosystem health and climate change in tandem, or risk undermining both. It’s a sobering reminder that the “safe operating space” for humanity is shrinking – and fast.

Underground CO₂ Storage Overestimated: As nations bet on carbon capture to meet climate goals, a new Nature study delivered a reality check: the world has far less capacity to store CO₂ underground than assumed ^[72]. Researchers re-evaluated all potential geologic storage sites (deep saline aquifers, depleted oil fields, etc.), excluding those with leakage risks, earthquake faults, or other constraints. The result: 90% less secure storage than prior estimates ^[73]. In numbers, that translates to only about 70 gigatons of CO₂ prudent to store – not the hundreds of gigatons once hoped. Lead author Dr. Matthew Gidden said this slashes carbon capture’s potential contribution: instead of shaving 5–6 °C off future warming (in fanciful scenarios), carbon storage might only avert around 0.7 °C of warming ^{[74] [75]}. “Carbon storage is often portrayed as a way out of the climate crisis. Our findings make clear it is a limited tool and reaffirms the extreme importance of reducing emissions as fast as possible,” Gidden emphasized ^[76]. This doesn’t mean carbon capture is useless – but it should be prioritized for sectors that can’t easily decarbonize (cement, aviation, etc.) and not used as a crutch to prolong fossil fuel power ^[77]. The study also noted that new techniques (like mineralizing CO₂ in basalt) could expand capacity, but aren’t proven at scale yet ^[78]. Commentary from independent experts (e.g. Stanford’s Rob Jackson) echoed the caution: relying on future carbon removal is risky if we’re unwilling to cut emissions now ^[79]. In short, carbon capture is not a silver bullet – deep emissions cuts remain non-negotiable to meet climate targets.

“Insect Apocalypse” Spreads to Wilderness: A troubling ecological study from the University of North Carolina showed that even untouched ecosystems are losing insects at alarming rates ^[80]. Over 15 summers, biologist Keith Sockman measured insect populations in a pristine subalpine meadow in Colorado – far from agriculture or urbanization. He documented a 6.6% annual decline in flying insects, totaling a ~72% collapse in abundance over two decades ^[81]. This site has minimal direct human impact, implicating climate change (rising summer temperatures) as a key driver of the decline ^{[82] [83]}. It fills an important gap: most insect decline reports have been in disturbed habitats (farmland, suburbs), leaving doubt whether “background” natural areas were spared. The answer, sadly, is no – even mountaintop meadows are not immune. “Insects have a unique, if inauspicious, position in the biodiversity crisis due to the ecological services they provide… and their vulnerability to environmental change,” Sockman noted, stressing that insects are essential for nutrient cycling, pollination, and ecosystems at large ^[84]. The fact that a remote, protected area can suffer such dramatic losses suggests a pervasive, climate-linked phenomenon. Mountains, often biodiversity hotspots of endemic species, may be especially at risk as temperatures rise ^[85]. The study, published in Ecology, calls for expanded long-term monitoring of insects in more wild landscapes ^[86]. It adds urgency to climate action and conservation – not just to save charismatic big animals, but the tiny critters underpinning entire food webs.

Plastic Waste Turned CO₂ Sponge: In a bit of encouraging news, chemists at University of Copenhagen unveiled BAETA, a new material that can both reduce plastic waste and fight climate change ^[87]. BAETA is made by upcycling common PET plastic (think water bottles) into a porous material that absorbs carbon dioxide from air or industrial emissions. The material acts like a “plastic-eating” CO₂ sponge, with high uptake capacity and stability over many cycles ^{[88] [89]}. “The beauty of this method is that we solve a problem without creating a new one,” said lead author Margarita Poderyte ^[90]. Essentially, they’re tackling plastic pollution and carbon capture in one stroke: waste PET is converted into BAETA, which can then strip CO₂ out of flue gases or the atmosphere. Lab tests show it works across a range of temperatures and remains effective over time ^[91]. The team is now scaling up production in hopes that BAETA could be deployed in factory smokestacks or even woven into building materials to passively soak up CO₂. This kind of circular economy innovation – turning trash into a climate solution – garnered excitement as a “win–win” technology ^[92]. While carbon capture alone won’t solve global warming, materials like BAETA could play a supporting role in reducing emissions (especially for hard-to-decarbonize sectors) while also reducing plastic litter. It’s a reminder that creative chemistry can sometimes kill two birds with one stone.

Biology & Ecology

Breakthrough in Antibiotic Discovery: In microbiology news, scientists achieved something of a holy grail – using AI to invent brand-new antibiotics. A team at University of Pennsylvania developed a generative AI model (called AMP-Diffusion) that designed thousands of novel antimicrobial peptides from scratch ^[93]. Unlike earlier approaches that mined existing molecules, this AI “imagined” completely new sequences of amino acids with bacteria-killing properties. The researchers then tested dozens of the AI’s top candidates in the lab: remarkably, two of the AI-designed antibiotics worked in animals, curing mice infected with drug-resistant superbugs as effectively as standard meds ^{[94] [95]}. The compounds also showed low toxicity to human cells. “Nature’s dataset is finite; with AI, we can design antibiotics evolution never tried,” said Dr. César de la Fuente ^[96]. Traditional antibiotic discovery has stagnated (no truly new class in decades) while bacteria evolve resistance, so this proof-of-concept is a big deal. The AI essentially functions like DALL·E or GPT, but for protein molecules – it “diffuses” random amino acid chains into optimized designs, guided by a large protein language model ^{[97] [98]}. The Penn team combined this with an AI filter trained on known antibiotic traits to winnow the candidates ^[99]. The end result, published in Cell Reports Physical Science, is not just theoretical: it yielded two experimental drugs that target MRSA and Acinetobacter (lethal hospital pathogens) by poking holes in their membranes. These AI-created antibiotics (which the team cheekily named after medieval swordsmen) illustrate how machine learning can turbocharge drug discovery. Next steps include optimizing the molecules further and testing against more pathogens. Experts heralded the study as a “milestone in antibiotic development,” showing that de novo AI design can deliver real drugs, not just paper ideas ^[100].

Rare “Virgin Birth” in Endangered Crocodile: (While not from a peer-reviewed study these two days, a fascinating biology story made headlines recently.) In a Costa Rican zoo, a female American crocodile was found to have laid a clutch of eggs that developed without any male fertilization, a phenomenon known as parthenogenesis. One egg contained a fully formed female fetus 99.9% genetically identical to the mother (essentially a clone) ^{[101] [102]}. Although that fetus was stillborn, the discovery (published in Biology Letters) is the first documented virgin birth in a crocodilian. Parthenogenesis is known in some birds, sharks, and reptiles like Komodo dragons, but never in crocs. It suggests the trait may date back to their distant ancestors – even dinosaurs might have had this ability in a pinch. The finding is raising intriguing questions: do other endangered crocodiles or alligators resort to virgin births when mates are scarce? From an evolutionary standpoint, parthenogenesis might be a last-ditch strategy for isolated females to produce offspring (albeit with no genetic diversity). While not part of the Sept 6–7 news per se, this story was widely shared in science media in early September and underscores nature’s astonishing reproductive plasticity.

Otter Comeback in India: (Another biodiversity note around this time was a heartening wildlife sighting.) Wildlife researchers conducting a tiger survey in India’s Satpura Tiger Reserve stumbled upon a surprise: the first-ever photos of smooth-coated otters in that region ^[103]. This otter species hadn’t been confirmed in those central Indian highlands before. Camera traps snapped images of an otter pair by a forest stream – a sign that conservation efforts are benefiting more than just tigers. The smooth-coated otter is threatened in parts of its range, so finding a new population expands its known distribution. Ecologists say this highlights the interconnectedness of preserving large landscapes: protect tiger habitat, and other shy creatures rebound or reveal themselves. Such encouraging discoveries provide a counterpoint to the grim news about biodiversity loss, showing that wildlife can recover if given space and protection.

(The above two items were notable biology news in early September, illustrating both nature’s wonders and conservation successes. While not major global “breakthroughs,” they add context to the period’s science happenings.)

Physics

Warp Drive Research – No “Exotic” Physics Required: It sounds like science fiction, but physicists are making headway on the concept of warp drives – and a new study claims they’ve resolved one of the biggest theoretical hurdles. Ever since Miguel Alcubierre’s 1994 paper, the idea of a warp drive (compressing spacetime in front of a ship and expanding it behind) was tantalizing but required “negative energy” – a substance that probably doesn’t exist. Now, Applied Physics researchers led by Dr. Jared Fuchs and Dr. Chris Helmerich propose a fully physical warp drive model that avoids exotic matter ^{[104] [105]}. Published in Classical and Quantum Gravity, their model describes a warp bubble using only normal positive energy (albeit a lot of it) by combining a shell of dense matter with a clever space-time geometry (a “shift vector distribution”) ^{[106] [107]}. The catch: their design likely yields subluminal warp – i.e. it can approach light speed, but not exceed it. Still, it would drastically surpass current propulsion limits without breaking relativity. In plain terms, they showed it’s theoretically possible to create the spacetime-distortion of a warp bubble under Einstein’s equations within the bounds of known physics. “Although such a design would still require a considerable amount of energy, it demonstrates that warp effects can be achieved without exotic forms of matter,” said co-author Dr. Helmerich, adding that this paves the way to eventually reducing the huge energy requirements ^[108]. Of course, building a warp drive remains far beyond our technology – but this work moves it from “impossible” to “perhaps one day, if we figure out the engineering.” The paper has generated buzz for providing a concrete mathematical blueprint that other physicists can now scrutinize or refine. It’s a reminder of how cutting-edge theoretical physics can inch ideas from sci-fi into the realm of serious discussion.

Why Ice Is Slippery – Mystery Cracked: For over 150 years, scientists believed ice’s slipperiness came from pressure or friction melting a thin water layer under your skates or shoes. However, new experiments by a German team led by Prof. Martin Müser have overturned this textbook explanation ^[109]. Using sensitive instruments and simulations, they found that neither the pressure of an object on ice nor frictional heating is the primary factor (in fact, ice can be slippery even at very low pressure and extremely cold temperatures). Instead, it’s about molecular forces: the electric dipoles in water molecules of the ice surface reorient when another material (like a shoe sole) contacts them, disrupting the crystal structure and creating an almost-liquid layer ^[110]. Essentially, the interaction between the two materials’ molecules produces a slippery film even without melting. This film can form even at –40 °C or colder, conditions under which the traditional pressure-melting theory can’t apply ^[111]. Müser explained, “The orientation of dipoles in the shoe sole interacting with those in the ice [creates] a disordered, almost liquid layer” – making ice slick regardless of temperature ^[112]. This discovery, reported in early September, is more than a fun fact about winter sports; it refines our understanding of solid-liquid interfaces and could improve designs for tires, footwear, or winter road treatments. By knowing the true cause of slipperiness, engineers might tailor materials that grip ice better (counteracting the dipole effect) or that exploit it when desired (like better ice skates). It’s a striking example of how something seemingly mundane – why we slip on ice – can lead to deep physics insights.

Graphene’s “Perfect Fluid” Defies a Law: A long-standing quantum puzzle was solved by researchers in India and Japan: electrons in graphene can flow like a near-perfect liquid, violating a classic law of physics. Normally, metals obey the Wiedemann–Franz law, which links electrical conductivity to thermal conductivity. But the team observed that in ultra-pure graphene at low temperature, as electric conductance went up, heat conductance went down – a 200× deviation from Wiedemann–Franz ^[113]. This happens at graphene’s “Dirac point,” where electrons act collectively like a fluid with almost no viscosity (analogous to the quark–gluon plasma in particle physics) ^[114]. The existence of this Dirac fluid was theorized but never clearly seen until now. “It is amazing that there is so much to do on just a single layer of graphene even after 20 years of discovery,” said Prof. Arindam Ghosh of IISc, a corresponding author ^[115]. The findings, published Sept 6 in Nature Physics, show that charge and heat transport can decouple via quantum effects – essentially rewriting the rules for 2D materials. Graphene’s electrons behaving as a “quantum perfect fluid” opens new avenues: such behavior could be harnessed in future quantum electronics or sensors that need ultra-sensitive thermal responses ^[116]. It also lets researchers tabletop-test theories from high-energy physics (like aspects of black hole thermodynamics) in a sheet of carbon atoms ^[117]. In short, graphene continues to surprise, bridging condensed matter and quantum physics in ways that challenge our fundamental assumptions.

Technology & AI

Generative AI Finds New Antibiotics: One of the most significant tech breakthroughs of the weekend came at the intersection of AI and medicine: researchers created an AI system that designs novel antibiotics – and it already yielded two promising drug candidates ^{[118] [119]}. The system, developed by a University of Pennsylvania team, uses a diffusion model (inspired by image generators like DALL·E) to “imagine” new antimicrobial peptides. After generating ~50,000 candidate molecules, the AI’s suggestions were filtered for potency and safety using additional algorithms ^[120]. From this, scientists synthesized a shortlist and found two peptides that can kill multi-drug-resistant bacteria in mice as effectively as existing antibiotics ^[121]. These AI-invented antibiotics, which did not resemble any known natural molecules, mark a new paradigm: de novo drug design by AI. The work was published in Cell Reports Physical Science and hailed by experts as a glimpse of the future of pharmaceutical innovation ^[122]. It addresses a critical need, as bacterial resistance has outpaced traditional antibiotic discovery. The fact that an AI conceived molecules that nature hadn’t evolved – yet that work in practice – is a powerful demonstration of AI’s creative potential in science. Moving forward, the approach could be expanded to design drugs for other hard-to-treat diseases, potentially cutting down discovery times from years to months. As Dr. de la Fuente enthused, this method “lets us design antibiotics evolution never tried”, effectively expanding the biochemical search space beyond what exists in nature ^[123].

Robots Dismantling EV Batteries: In green technology, an EU-funded project called Recirculate announced a successful prototype of an AI- and robotics-driven EV battery recycling system ^[124]. Recycling electric vehicle batteries is notoriously difficult – they’re heavy, dangerous, and assembled with dozens of screws and cells. Recirculate’s solution: a robotic cell with machine learning models that identify and disassemble battery packs automatically. The robot (a modified KUKA industrial arm on rails) uses cameras and trained AI to locate every screw and component, then unscrew and remove them in sequence ^{[125] [126]}. It even has a computer vision model to identify battery types (e.g. Tesla vs. Nissan packs) on the fly, so it can adjust the disassembly plan accordingly ^[127]. In tests, the system can tear down packs more safely and quickly than manual methods, which addresses a key bottleneck in scaling EV recycling. “This is one of the first real-world examples of battery disassembly using machine learning and robotics,” said Tomi Pitkäaho of Finland’s Centria University, a project lead ^[128]. By automating pack-to-cell disassembly, valuable materials like cobalt, nickel, and lithium can be recovered more economically – reducing the need for mining. The announcement (with first-phase results published Sept 5) shows how AI and robotics are accelerating clean-tech and circular economy solutions. As EV adoption surges, such innovations will be crucial to prevent used batteries from piling up and to make electric mobility truly sustainable.

Anthropic’s Big AI Funding & OpenAI Updates: In AI industry news, startup Anthropic (maker of the Claude chatbot) raised a staggering $1.3 billion in new funding at a valuation of $18.3 billion ^[129]. This underscores the ongoing AI investment frenzy as companies race to build ever-more capable AI models (Anthropic is working on a next-gen “Claude 2” to rival OpenAI’s GPT-4). Meanwhile, OpenAI rolled out major updates to ChatGPT: users can now create branching conversations (forking chat threads to try different prompts without losing context) and organize their chats into projects with shared files ^{[130] [131]}. They also integrated their coding assistant “Codex” more deeply – it’s now available across platforms (terminal, VSCode, etc.) under one account with memory of past interactions ^[132]. These upgrades aim to make AI assistants more practical for day-to-day workflows. For example, branching chat lets you experiment with multiple solutions from the same starting point – described by OpenAI as the difference between “a tidy lab notebook and scribbles on a napkin” in terms of keeping your work organized ^[133]. The rapid iteration of such features highlights how competitive the AI assistant space has become, with companies adding capabilities to attract users (and enterprise clients). On the policy side, there were also discussions around AI in schools – even the U.S. First Lady weighed in, encouraging the integration of AI tools in classrooms amid some public backlash ^[134]. All told, the first week of September saw AI making strides both in cutting-edge applications (like drug discovery) and in the maturation of AI products we use every day.
