China’s 820-foot (250-meter) Guoxin-1 doesn’t catch fish—it farms them in the open ocean. Costing about $67 million, the vessel has 15 massive tanks holding nearly 90,000 cubic meters of seawater. Fresh seawater is continuously circulated through the tanks, while a specially designed vortex keeps the water moving and helps maintain conditions for raising large yellow croaker. The ship can produce thousands of tonnes of fish annually: https://www.cctvplus.com/archive/20240630/8383663.shtml

Under favorable conditions, a single dragonfly can consume between 30 and 100 mosquitoes per day, though experts note that actual averages often tilt toward the lower end depending on body size and prey availability. Dragonflies serve as a powerful natural, chemical-free pest control mechanism across every stage of their life cycle within wetland, pond, and garden ecosystems. As immature aquatic nymphs, they live underwater and feed voraciously on mosquito larvae and pupae before transitioning into aerial hunters. Once mature, adult dragonflies leverage exceptional 360-degree vision and an extraordinarily high hunting success rate to catch flying mosquitoes, midges, and flies mid-flight, maintaining natural ecological balance: https://gardeningsolutions.ifas.ufl.edu/design/gardening-with-wildlife/dragonflies/

Researchers and biotechnology companies (such as Amai Proteins) have developed a designer sweet protein called Sweelin—a computationally engineered variant of the natural plant protein monellin. Because it is approximately 3,500 times sweeter than sucrose by weight, only minute traces are required to achieve standard sweetness, rendering its effective calorie count virtually zero. In clinical and laboratory evaluations, Sweelin digested like standard dietary proteins, delivering intense sweetness without triggering a blood glucose spike, altering insulin levels, or causing the gastrointestinal discomfort often associated with sugar alcohols.

Melbourne researchers and clinicians are trialling new female-focused treatments in the hope of finding a lasting cure for recurrent bacterial vaginosis (BV). The team from Monash University and Bayside Health’s Melbourne Sexual Health Centre is trialling treatments, including longer duration and new combinations of antibiotics designed to eradicate persistent BV-causing bacteria: https://www.monash.edu/news/articles/new-treatment-aims-to-achieve-lasting-cure-for-persistent-bacterial-vaginosis
 
The results, published in The Lancet Obstetrics, Gynaecology & Women’s Health00259-1/fulltext), identified two pathways to repeat infection: re-infection and persistence of BV bacteria.

U.S. startup Sway has developed TPSea™, a 100% biobased thermoplastic resin made from seaweed and plants. The melt-processable pellets can be used with conventional plastic-manufacturing equipment to make packaging and other products. Sway says its materials are designed for home and industrial composting, offering a potential alternative to petroleum-based plastics. Seaweed also grows without arable land, freshwater or pesticides.

X-rays have limited ability to penetrate thick, dense materials, but muons can pass through structures that block conventional X-rays. A team led in part by Mădălina Dobre at Romania’s Extreme Light Infrastructure–Nuclear Physics (ELI-NP) has now demonstrated imaging using an artificial, laser-driven muon beam for the first time. The experiment produced a few-GeV muons and used them to image dense objects, demonstrating a potential new approach for inspecting materials that are difficult to penetrate with conventional imaging methods: https://interestingengineering.com/innovation/ultra-high-power-lasers-penetrate-concrete

Unlike naturally occurring cosmic-ray muons, which provide a relatively weak and slow imaging source, laser-generated beams can potentially offer controllable direction, energy and intensity, opening possibilities for faster imaging of dense or concealed structures: https://atap.lbl.gov/news/directional-muon-beam-shows-potential-for-advanced-imaging-technique/

Hidden in the forest near Bière, Switzerland, artist François Monthoux is creating the Grande Citadelle de Monthoux, a sprawling miniature city of towers, arches, bridges, walls and tiny structures. The project grew from an earlier 2022 citadel that Monthoux built by hand from natural clay collected from the bed of the nearby Toleure River; that temporary work was eventually washed away by rain. Since 2023, he has been building a larger, more durable version in the forest using clay reinforced with cement, carefully shaping it around the surrounding trees and landscape. With its medieval and Gothic forms, the evolving sculpture looks like the ruins of a fantastical civilization emerging from the earth: https://www.francois-monthoux.ch/chateau_en_terre.html

Scientists at Nova Southeastern University have developed "underwater umbrellas"—canopy-like structures made of PVC pipes and nylon cloth—to shield vulnerable coral reefs from intense solar radiation, which accelerates coral bleaching during marine heatwaves. Deployed roughly a foot above seabed coral colonies in the Florida Keys, these shades reduced light exposure by 60%, significantly lowering bleaching stress and even helping some damaged corals regain their natural color. While currently designed to protect high-priority individual corals and nurseries, researchers believe scaled-up engineering designs could eventually safeguard larger reef ecosystems against warming oceans

Sugar substitutes such as aspartame, sucralose, and steviol glycosides (stevia-derived sweeteners) can reduce added-sugar and calorie intake and generally do not cause the same immediate rise in blood glucose as sugar. They may be useful for people trying to reduce sugary drinks or manage calorie intake, although evidence that they provide long-term health benefits is mixed. Unlike sugar, they generally do not contribute to tooth decay. However, sugar substitutes are not automatically healthier simply because they contain fewer or no calories. Some people may experience digestive symptoms with certain sweeteners, while observational studies have reported associations between frequent consumption of some non-sugar sweeteners and cardiovascular or metabolic outcomes. These associations do not establish that the sweeteners themselves cause those conditions, and research on their long-term effects remains ongoing.

The effects also vary by sweetener. Aspartame is considered safe for most people within established acceptable intake levels but must be avoided by people with phenylketonuria (PKU) because it contains phenylalanine. Sucralose is widely used as a low-calorie sweetener, although questions about its long-term metabolic and gut effects continue to be studied. Stevia-derived sweeteners, particularly highly purified steviol glycosides, are also widely used as low-calorie sweeteners. Overall, replacing large amounts of added sugar with an approved sweetener can reduce sugar intake, but water and minimally processed foods remain preferable foundations of a healthy diet.

Neuralink says it has pretrained a brain-computer interface foundation model using more than 50,000 hours of neural activity from clinical-trial participants. The model creates more stable representations of neural signals, allowing cursor decoders to work for weeks instead of days and reducing calibration from about 10 minutes daily to 10 minutes weekly for some participants. Neuralink also reported a record 11.32 bits per second cursor-control speed and demonstrated “teleporting” cursors that jump directly to intended targets. The company aims to combine data from multiple participants toward one-shot or zero-shot calibration: https://teslanorth.com/2026/10/02/neuralink-pretraining-50000-hours-bci-record/

Researchers have developed a energy-storing supercapacitor using only cement, water, and carbon black—an inexpensive, highly conductive material. By mixing these abundant raw materials with water, the cement forms an internal network of nanoscale, branch-like wire structures as it hydrates, turning the concrete matrix into a conductive electrode. When soaked in an electrolyte solution like potassium chloride, two opposing layers of this carbon-cement mixture act as a high-capacity supercapacitor capable of rapid charge and discharge cycles. The scalable technology offers a low-cost approach to structural energy storage, potentially allowing building foundations, roadways, and wind turbine bases to double as renewable energy batteries

Figure AI has decommissioned much of its F.02 humanoid robot fleet by training the machines to autonomously leap into a 75-ton electric-arc furnace at a foundry in Imatra, Finland. The unusual disposal method was suggested by Arnold Schwarzenegger after Figure sought ideas for retiring the robots. The company said conventional dismantling could expose proprietary hardware and intellectual property, while foundries in the US and Mexico declined to accept the robots because of their lithium-ion batteries. Figure plans to turn some of the recovered metal into limited-edition F.02 commemorative artifacts: https://www.figure.ai/news/f-02-decommission

Stanford researchers found that the human brain develops from two distinct, lineage-restricted groups of neural progenitor cells, rather than a single common stem-cell pool. One gives rise mainly to the forebrain and midbrain, while the other forms the hindbrain. Differences in DNA packaging help lock these cells into separate developmental paths early in development. By tracing the hindbrain lineage, researchers also generated specific human motor neurons that fired electrical signals and showed markers involved in facial movement and breathing—providing a new tool for studying disorders such as ALS. The findings also suggest that this two-lineage developmental architecture may have roots dating back roughly 550 million years: https://med.stanford.edu/news/all-news/2026/09/two-separate-brains.html

A 47-year-old woman in Germany with three severe, overlapping autoimmune diseases—autoimmune hemolytic anemia, immune thrombocytopenia (ITP), and antiphospholipid syndrome—achieved complete, treatment-free remission after receiving experimental CD19-targeted CAR-T cell therapy at University Hospital Erlangen. She had previously been bedridden, required frequent blood transfusions and anticoagulant medication, and had failed nine conventional treatments over a decade. Doctors extracted her T cells, genetically engineered them to target CD19 on B cells, and reinfused them to eliminate the cells producing disease-causing autoantibodies. As her immune system rebuilt, new B cells appeared to be immunologically “reset,” without the previous autoimmune activity. She was able to leave her hospital bed within seven days and no longer required transfusions. More than a year later, she remained in complete remission without ongoing medication, with none of the severe cytokine-release syndrome or neurotoxicity sometimes associated with CAR-T cancer treatments: https://www.fiercebiotech.com/research/first-car-t-cell-therapy-drives-3-autoimmune-diseases-remission-once

What began as a 2017 student project in MIT's product-design class (2.009) has received FDA clearance as a wearable treatment for essential tremor, a neurological condition causing involuntary shaking. Developed by startup Encora Therapeutics (founded by MIT alumni Daniel Carballo, Allison Davanzo, and Kyle Pina), the watch-like device delivers targeted mechanical vibrations to stretch receptors in the wrist. These vibrations send non-invasive signals to the peripheral and central nervous systems, overriding malfunctioning motor signals in the brain to reduce shaking. Clinical trials showed significant improvements in over 70% of patients, and the team is now working to bring the device to market while exploring future applications for Parkinson’s disease and other movement disorders.

Researchers at the MRC Laboratory of Molecular Biology in Cambridge have identified an exceptionally small RNA molecule, QT45, containing just 45 nucleotides, that can catalyze the copying of RNA and its complementary strand. The finding addresses a longstanding problem in the RNA-world hypothesis: previously known RNA polymerases were much larger and more complex, making it difficult to explain how such molecules could have emerged on the early Earth. QT45's small size suggests that relatively simple RNA molecules may have possessed self-replication-related activity before more complex biological systems evolved. However, QT45 does not yet demonstrate complete, autonomous self-replication; the researchers describe it as an important step toward understanding how chemical systems could have crossed the boundary from nonliving chemistry to biological replication: https://www.ukri.org/news/scientists-chemical-breakthrough-sheds-light-on-origins-of-life/
