Science · 2026-08-29 · 1 min read Earth Microbes Survive Moon Shadows NASA-led modeling in Science Advances finds human-associated bacteria and fungi could survive days in shaded niches near the lunar south pole, including Artemis III candidate sites. Using Lunar Reconnaissance Orbiter maps of Nobile Rim, Connecting Ridge, and De Gerlache Rim, researchers tested organisms common on skin and spacecraft such as Aspergillus niger, Bacillus subtilis, and Deinococcus radiodurans. Survivable pockets ranged from crater floors to boot- print scale; hardy Aspergillus resisted UV enough to persist even with some sunlight, up to about a week in places. Survival here means dormancy, not growth: no liquid water or atmosphere for replication. Scientists warn hitchhiking microbes could confuse searches for pristine lunar chemistry and complicate Mars life detection, urging baseline contamination controls before crewed south-pole landings turn the Moon into an accidental biology experiment.

Science · 2026-08-29 · 1 min Cancer CAR-T Puts Arthritis In Remission Charité researchers in Berlin tested CD19 CAR T-cell therapy in six people with severe, treatment-refractory rheumatoid arthritis, the world's first such trial, ScienceDaily reported from a Nature Medicine paper dated Aug. 29. Three women and three men, ages 31 to 69, had failed as many as eight targeted or biologic therapies over a decade. Doctors collected each patient's T cells, engineered them to hunt the CD19 marker on disease-driving B cells, gave brief preparatory chemotherapy, then a single infusion. Disease activity fell in all six. Over follow-up of up to one year, three stayed in medication-free remission. The modified cells reached B cells in bone marrow, lymph nodes, and joint tissue. Autoantibodies dropped; vaccine antibodies to chickenpox and tetanus remained. One patient's disease returned after an initial medication-free stretch. Safety: only temporary mild-to-moderate cytokine release syndrome, no severe neurological events. Phase two will add ten patients and compare CAR T with an approved B-cell drug. Kyverna supported the study but did not design or analyze it. Science · 2026-08-29 · 1 min Roman Telescope Launches Sunday Morning NASA’s $4.3 billion Nancy Grace Roman Space Telescope is targeted for 7:26 a.m. EDT Sunday, Aug. 30, on a SpaceX Falcon Heavy from Kennedy Space Center pad 39A. Space Force weather officers put favorable conditions at 60 percent. The 42-foot, 18,000-pound observatory carries a 7.9-foot Hubble-class mirror the National Reconnaissance Office donated after a spy-satellite program was canceled. Bound for Sun-Earth L2, about a million miles from Earth, Roman is designed to scan the sky 1,000 times faster than Hubble. Its 300-megapixel wide- field camera will downlink about 2,500 terabytes over a five-year primary mission, versus Hubble’s 172 terabytes in 30 years. NASA Administrator Jared Isaacman said it will “give the Earth a new atlas of the universe.” Science chief Niki Fox called it “a sheer powerhouse.” The flagship is launching nine months early and will hunt dark energy, dark matter, and more than 100,000 exoplanets. Science · 2026-08-29 · 1 min Frozen Frogs Restart After Hearts Stop A North American wood frog can spend winter looking dead and still hop away in spring. Up to 65 to 70 percent of its body water freezes around the brain, lungs, heart, and eyes, while ice is kept mostly outside cells so membranes survive. Heartbeat, breathing, and obvious brain activity stop. Before the last beat, the heart briefly races to pump glucose from the liver; that sugar, plus urea, limits ice, holds cell volume, and protects proteins. Alaskan frogs have survived minus 16 Celsius, and field sites stayed below the freezing point for an average of 193 days under snow and leaf litter. Thawing is a sequence, not a reset: the heart restarts first, then breathing and reflexes. Endurance can stay reduced for days. Cryobiologists study the trick for organ preservation, but the frog is not a recipe for freezing humans. It evolved a whole-body system that a lone mammalian organ does not have. Science · 2026-08-29 · 1 min Shark Graveyard Found in Egyptian Desert Paleontologists led by Cairo University's Tarek Yassin pulled 14 fossil shark teeth from phosphate beds on Egypt's Abu-Tartur Plateau, a stretch of Western Desert that was a shallow inland sea about 80 million years ago. The teeth, some needle-like, others broad and serrated, belong to at least five extinct lamniform species new to the site, bringing the local total to seven. Two species had never been reported in Egypt; an ancient goblin-shark relative, Scapanorhynchus raphiodon, may be the first known from Africa and possibly the youngest specimen of its kind. Shark skeletons are cartilage, so teeth are the record. Crow sharks hint at nearshore waters; goblin-shark kin hint at deeper shelf and slope, so the 'graveyard' is a mixed, nutrient-rich Tethys margin, not one pile of animals that died together. The sea later retreated as levels fell and tectonics shut Egypt's link to the Tethys, leaving seafloor as desert. The paper is in Cretaceous Research. Science · 2026-08-29 · 1 min AI Maps Six Hidden Earth Structures About 1,800 miles beneath your feet, Earth's mantle meets the liquid outer core. Chinese Academy of Sciences researchers trained a deep-learning system on more than two million earthquake recordings from 1990 to 2024, then hand-corrected the model's mistakes. It pulled out 174,929 faint PKP precursor signals—more than ten times all earlier catalogs—waves that scatter off lumps near the core-mantle boundary and arrive just before stronger waves. The new map shows patches once thought isolated actually join into larger belts. Six poorly sampled zones, labeled B1 to B6, including high-latitude Eurasia, Central Asia, and the South Atlantic, now look like major hidden heterogeneities. The team thinks they may be thermochemical piles: leftover subducted slabs, partial melt, mineral transitions, or leftovers from the object that made the Moon, interacting with giant low-shear-velocity blobs. Those deep structures can steer mantle flow, magma, volcanoes, and even the magnetic field. The study is in the Journal of Geophysical Research: Solid Earth.
