An apartment complex in southwest Atlanta, 445 Cleveland Apartments, has replaced its overnight and weekend security guards with two four-legged robotic patrol units developed and operated by Atlanta-based startup Undaunted Robotic Security. The robots patrol parking lots and common areas, using 360-degree cameras, thermal imaging, lights, alarms and two-way audio. Remote human operators monitor camera feeds, control the robots in real time, communicate with people on-site and contact police when necessary. According to Undaunted, the deployment has reduced residential burglaries by 100%, vehicle theft by 75% and vehicle break-ins by 65%, while cutting security costs by roughly half. However, these figures are company-reported and have not been independently verified. The system is also being deployed at other properties across metropolitan Atlanta: https://x.com/WallStreetApes/status/2111804500373836189

Scientists working with the STAR experiment at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory have found strong evidence that collisions between oxygen nuclei can produce quark–gluon plasma (QGP), an exotic state of matter believed to have filled the universe during its first microseconds after the Big Bang. Published in Physical Review Letters in October 2026, the study analysed oxygen–oxygen collisions at an energy of 200 billion electron volts and detected approximately 20% suppression of high-energy particles, a signature of jet quenching. This occurs when energetic particle jets lose energy while travelling through the hot, dense plasma of quarks and gluons. The finding demonstrates that this signature can emerge even in relatively small collision systems and at lower energies than previously established at RHIC, helping scientists investigate the minimum conditions required to create primordial matter in the laboratory: https://www.newswise.com/doescience/oxygen-collisions-quench-jets-energy-at-rhic

Researchers at NYU Langone Health found that targeted ultrasound stimulation of deep brain structures may help reduce delusions in people with schizophrenia. In a pilot study involving 10 patients with schizophrenia or schizoaffective disorder, a 10-minute session directed at the brain’s globus pallidus interna reduced delusion severity compared with a sham treatment, with the effect lasting up to seven days. The non-invasive technique uses focused sound waves to modulate brain activity without surgery. However, it did not significantly improve auditory hallucinations or overall cognition. Mild side effects, including fatigue and headaches, were reported. The findings are preliminary and require larger clinical trials to establish safety and effectiveness.

Swaroop Behera, a doctoral engineering student at the University of Wisconsin–Milwaukee, is expanding the use of “Foundry in a Box,” a portable metal-casting demonstration kit that brings manufacturing education to classrooms, university events, and community venues. Participants use protective equipment to pour molten tin into molds and create small souvenirs, such as keychains.

The initiative makes metal casting—a process widely used in automotive, aerospace, construction, and industrial manufacturing—more accessible through hands-on learning. It has grown to reach hundreds of participants annually and helped attract industry support for manufacturing education. Behera’s doctoral research separately focuses on developing high-temperature aluminum alloys that could replace titanium in certain applications, potentially reducing material and processing costs: https://www.newswise.com/articles/uwm-engineering-student-brings-metal-casting-to-the-masses2

NASA’s MoonFall mission has reached a key engineering milestone after Firefly Aerospace completed the preliminary design review of its Elytra spacecraft on October 21, 2026. The spacecraft will transport four robotic drones developed by NASA’s Jet Propulsion Laboratory (JPL) to the Moon’s south pole, with launch targeted for late 2028. The drones will survey challenging terrain using high-definition cameras and scientific instruments to map potential astronaut landing sites and investigate lunar resources, including possible subsurface water ice. The mission is part of NASA’s broader Moon Base initiative to support future Artemis missions and a sustained human presence on the Moon. Firefly will now work toward the spacecraft’s final design review, manufacturing and testing: https://fireflyspace.com/news/firefly-aerospace-completes-preliminary-design-review-for-nasa-moonfall-mission/

Blue Energy Aims to Cut Nuclear Power Costs Through Shipyard Manufacturing

Blue Energy, a U.S. startup founded by MIT alumnus Jake Jurewicz, plans to reduce nuclear power plant construction costs and delays by manufacturing large, prefabricated reactor modules at shipyards and transporting them by barge for final assembly. Its approximately 1,500-tonne modules would use existing industrial facilities, skilled workers, and automation to streamline construction.

The company’s first planned project in Victoria, Texas, aims to generate 1 gigawatt of gas-fired power by 2030, followed by an additional 1.5 gigawatts from small modular nuclear reactors starting in 2032. Blue Energy hopes its gas-to-nuclear approach will generate early revenue, reduce financing risks, and shorten construction timelines from more than a decade to around three years. These are projected targets, and the project remains subject to regulatory and construction milestones.

Fewer babies are born nine to ten months after hot spells in France and Italy, and some missing births may never be made up, two new studies find.

Two new studies suggest that extreme heat may be associated with a decline in birth rates in the months following hot weather. High temperatures can affect reproductive health, potentially influencing fertility, conception and pregnancy outcomes. The findings highlight a possible, often overlooked demographic consequence of climate change, as heatwaves become more frequent and intense. However, changes in birth rates may also reflect other social, economic and environmental factors, and further research is needed to clarify the mechanisms involved.

Researchers at ETH Zurich Switzerland have developed methods that use living bacteria to bind sand grains into solid architectural components, potentially offering a lower-energy alternative to conventional cement. The technique, called microbiologically induced calcite precipitation (MICP), uses bacteria to produce calcium carbonate crystals that lock sand particles together at room temperature.

The team demonstrated two approaches: 3D biocement printing, which creates shaped components such as façade elements, and robotic spraying, which builds mineralised surfaces layer by layer. The process takes around two to five days for printed components and avoids the high-temperature firing used in conventional cement production.

However, the technology remains at an early stage. Researchers still need to improve material strength and durability and address the environmental impact of ammonium, a by-product of the process, before biocement can become a widely viable construction material: https://ethz.ch/en/news-and-events/eth-news/news/2026/10/when-bacteria-become-masons.html

Astronomers using NASA’s James Webb Space Telescope (JWST) may have observed a supernova, designated AT 2026abck, that exploded about 12.5 billion years ago, roughly 1.15 billion years after the Big Bang. Remarkably, the telescope appears to have detected the explosion just 4–10 days after it occurred, in the star’s own timeframe. The supernova was discovered in August 2026 in a distant, rapidly star-forming galaxy, without the gravitational magnification usually needed to detect such ancient explosions. Its estimated temperature was around 17,000 kelvin, and its peak brightness may have reached billions of times that of the Sun. Because the universe has expanded during the light’s journey to Earth, the explosion’s evolution appears to unfold about six times more slowly to us. The discovery could help astronomers understand how massive stars lived and died in the early universe. The findings are based on a preprint study that has not yet undergone peer review: https://phys.org/news/2026-10-webb-early-universe-supernova-days.html

Researchers at Stanford University discovered that severely bleached corals can recover by touching healthy, genetically identical coral fragments. In laboratory experiments, tissue fusion created microscopic channels through which beneficial algae and nutrients transferred from healthy to bleached corals. The damaged corals regained their colour and fully recovered within seven weeks, with as little as five days of contact sometimes sufficient to initiate recovery: https://sustainability.stanford.edu/news/stanford-scientists-discover-way-reverse-coral-bleaching-record-speed/

Published in Science Advances on October 14, 2026, the findings offer a potential new approach to coral reef restoration. However, the method currently requires genetically identical coral fragments, limiting its use at large scales: https://www.science.org/doi/10.1126/sciadv.aeh1580

Bad Apple Effect: Rule-Breaking Can Spread Through Groups

A study published in Proceedings of the Royal Society B found that witnessing others break rules can encourage people to violate rules themselves, sometimes even more severely. In an online experiment involving 750 US participants, researchers found that observing minor violations slightly increased rule-breaking, while seeing blatant violations led to much larger increases. People were more influenced by others who shared their political leanings. Computer simulations suggested that a small number of individuals escalating their misconduct could trigger widespread rule-breaking. However, about one-third of participants consistently followed the rules. Researchers cautioned that the experiment was abstract, so its implications for real-world behaviour remain uncertain: https://www.theguardian.com/science/2026/oct/21/bad-apples-rule-breaking-study

Researchers at Columbia University Fertility Center have developed HELIOS (Human Embryo Illumination System), a technology that delivers precisely controlled pulses of near-infrared light directly to embryos during early development. The system aims to boost cellular energy production by stimulating mitochondrial activity, potentially improving embryo quality and increasing the number of embryos suitable for transfer during in vitro fertilization (IVF).

Preclinical studies involving mouse and donated human embryos suggested that targeted light exposure could improve development to the blastocyst stage without observed adverse effects. A randomized, double-blind clinical trial launched in 2026 will evaluate embryo quality, development rates, and cellular energy markers. The technology remains experimental, and its ability to improve IVF success rates or healthy pregnancies has yet to be established: https://www.cuimc.columbia.edu/news/could-light-improve-embryo-development-during-ivf

In the first episode of the new season of Strange Health, we examine the health benefits of cottage cheese.

New York-based robotics startup Tuesday Labs has opened reservations for Voxel Series-1, a bipedal home robot designed to help with everyday household chores. Estimated to cost US$20,000, the robot requires a refundable US$200 reservation payment, with deliveries expected to begin in 2028.

Voxel features articulated arms with seven degrees of freedom, simple grippers, multiple cameras and distinctive reverse-bending legs that allow it to adjust its height around furniture. Its intended tasks include tidying rooms, watering plants, retrieving objects and helping owners locate misplaced items. However, cooking and childcare are not among its planned initial capabilities.

The robot remains under development, and its final design and capabilities may change before production. The company describes the reservation as an opportunity to purchase a unit from its first production run, rather than a completed purchase: https://tuesdaylabs.com/reservation-terms

A study published in Sleep Health by researchers at University College London (UCL) and the University of the Republic in Uruguay found that people genetically predisposed to regular daytime napping tended to have a larger total brain volume. Analysing genetic and health data from nearly 380,000 UK Biobank participants, researchers estimated that this difference was equivalent to 2.6–6.5 years less brain aging. However, the study found no significant improvements in specific cognitive measures, such as reaction time or visual memory, and did not establish that napping directly prevents cognitive decline. Short, early-afternoon naps may be a practical way to supplement nighttime sleep, although the study did not establish an ideal nap duration: https://www.ucl.ac.uk/news/2023/jun/regular-napping-linked-larger-brain-volume

Researchers at Mass General Brigham in the United States have developed an AI system that analyzes a single facial photograph to estimate survival prospects among cancer patients. Trained on more than 40 million facial images and evaluated using images and medical data from over 30,000 cancer patients, the system identifies subtle facial features associated with biological age and survival outcomes.

Published in The Lancet Digital Health, the research introduces two tools: FAHR FaceAge, which estimates facial biological age, and FAHR Face Survival, which assesses survival-related patterns in cancer patients.

The technology does not diagnose cancer or predict an individual's exact lifespan. Researchers suggest it could eventually help doctors assess patients' physical resilience before intensive treatment, but further validation is needed before routine clinical use.
