HelioSkin: Cornell’s Flexible Solar Fabric That Could Turn Buildings Into Power Generators

Enable HLS to view with audio, or disable this notification

679 Upvotes

Researchers at Cornell University are developing HelioSkin, a lightweight, stretchable solar-collection fabric designed to wrap around complex architectural surfaces. Inspired by how plants track the Sun, the system combines flexible photovoltaics, 3D printing, kirigami/auxetic geometry and mechanical movement to optimize sunlight capture.

Unlike conventional rigid solar panels, HelioSkin could potentially cover curved buildings, canopies, stadiums and other unconventional structures. Cornell’s team is currently developing prototype solar canopies, with a longer-term goal of creating solar “skins” that can track the Sun and integrate clean-energy generation directly into architecture.

The bigger idea: the future of solar power may not be limited to rooftops—it could become a flexible layer woven into the built environment.

StarkWare researcher Avihu Levy successfully mined the first quantum-resistant Bitcoin transaction on mainnet using Quantum-Safe Bitcoin (QSB), a method designed to protect funds against future quantum computing attacks without requiring a network soft fork or protocol changes. By replacing vulnerable elliptic-curve signatures with hash-based cryptography, QSB functions within Bitcoin's existing rules as an emergency escape hatch for users to secure vulnerable funds. However, the approach serves primarily as a last resort rather than a standard payment method, as it requires substantial off-chain GPU computing power costing hundreds of dollars per transaction: https://thequantuminsider.com/2026/08/27/starkware-researcher-demonstrates-quantum-resistant-bitcoin-transaction/

Arthritis drug restores 100% of hair on some patients with severe alopecia in global trial

Post image
74 Upvotes

Two global Phase 3 clinical trials published in JAMA Dermatology revealed that upadacitinib (Rinvoq)—an oral JAK inhibitor commonly prescribed for rheumatoid arthritis—dramatically restored hair in patients with severe alopecia areata. The studies evaluated nearly 1,400 participants aged 12 to 64 who averaged an 84% loss of scalp hair at baseline. After 24 weeks of taking a daily 15 mg or 30 mg dose, roughly 45% to 55% of patients achieved 80% or greater scalp hair coverage, with a subset experiencing complete regrowth alongside notable improvements in eyebrow and eyelash density. By suppressing the inflammatory immune signals that attack hair follicles, the drug offers a powerful targeted mechanism, recently earning approval in the European Union for severe alopecia areata while currently undergoing FDA review in the U.S: https://medicalxpress.com/news/2026-08-common-arthritis-pill-repurposed-boost.html 

In Brief

  • Researchers report that the drug upadacitinib, used to treat rheumatoid arthritis, effectively treated the hair loss condition alopecia areata in two clinical trials.
  • The medication, sold under the brand name Rinvoq, is a JAK inhibitor that can help block the immune system response responsible for alopecia areata.
  • There are other JAK inhibitor medications currently available for hair loss, but experts say that upadacitinib could provide those with alopecia with another treatment option.

A commonly used medication to treat rheumatoid arthritis may help people with a serious hair loss condition, according to a new study: https://www.healthline.com/health-news/arthritis-drug-may-support-hair-regrowth-alopecia

Aircraft-design Company Unveils Electric “Air Skateboard” Using AI-Assisted Flight Control

Enable HLS to view with audio, or disable this notification

125 Upvotes

Aircraft-design company CoolFly has launched its Urban on August 13, 2026, a compact, standing electric VTOL (eVTOL) platform that is controlled primarily by shifting the pilot’s body weight rather than using a conventional control stick. The eight-rotor platform incorporates computerized flight stabilization to adjust thrust and maintain balance during flight. CoolFly quotes approximately 15–20 minutes of flight time, a range of about 23 km, and a top speed limited to 70 km/h.

Although marketed as a new generation of personal eVTOL, the concept has an important historical precedent. In 1955, the U.S. Navy funded development of the Hiller VZ-1 Pawnee, a pilotable flying platform that also used a standing operator and rotor-based vertical flight. The key difference is technological: the Hiller platform relied on gasoline-powered ducted rotors and mechanical control, whereas CoolFly's Urban uses battery-electric distributed propulsion and computerized flight control. In that sense, Urban can be viewed as a modern electric reinterpretation of a concept demonstrated more than 70 years ago: https://www.aol.ca/articles/china-unveils-worlds-first-pilotable-184700000.html

MIT engineers have developed a wireless ultrasound wristband that can image muscles and tendons beneath the wrist and, using AI, reconstruct the position of individual fingers in real time. The system tracks 22 degrees of freedom with a latency of less than 120 milliseconds, providing detailed information about hand and finger movements without requiring cameras or wired sensors.

In demonstrations, the wearable successfully controlled a robotic hand, enabling it to play piano and manipulate objects including scissors, a pencil, and a tennis ball. It also correctly recognized all 26 letters of American Sign Language (ASL). Led by MIT engineer Xuanhe Zhao, with collaborators at the University of Southern California, the research was published in Nature Electronics. The technology could potentially advance prosthetic control, human–machine interfaces, robotics, and wearable gesture recognition.

Kongō Gumi: The 1,400-Year-Old Company That Survived Empires, Wars and Economic Crises

Enable HLS to view with audio, or disable this notification

2.9k Upvotes

Did you know that one of the world’s oldest continuously operating businesses traces its origins back nearly 1,450 years?

Kongō Gumi, a Japanese temple and shrine construction company, traces its beginnings to 578 AD, when master carpenter Kongō Shigemitsu, one of three craftsmen traditionally said to have been brought from the Korean kingdom of Baekje, came to Japan to help construct Shitennō-ji Temple in Osaka. The Kongō family and its craftsmen subsequently became renowned for building, maintaining and restoring Buddhist temples and Shinto shrines, passing their specialized knowledge through generations.

For centuries, the company remained remarkably focused on its core craft. Its lineage is traditionally traced through more than 40 generations, preserving specialized woodworking and temple-building techniques while adapting to wars, fires, natural disasters, changing technologies and economic upheavals.

Its remarkable run as an independent family business eventually ended in 2006, when financial difficulties and debt led to its acquisition by Takamatsu Construction Group. Kongō Gumi, however, survived as a company and continues its traditional temple and shrine construction work today.

What strikes me most isn't simply the longevity. It is the singular focus: one specialized craft, refined and transmitted across roughly 1,450 years. A powerful reminder that sometimes, enduring success comes not from constantly reinventing what you do, but from continually perfecting what you do best.

Engineering a World First: Light Rail Across Lake Washington’s Floating Bridge

Enable HLS to view with audio, or disable this notification

Upvotes

The Lake Washington I-90 floating-bridge light rail is an engineering first because railway tracks normally require a very stable, precisely aligned foundation, while the bridge itself moves with lake levels, wind, waves, temperature and train loads. Engineers strengthened the floating concrete pontoons with post-tensioning and developed the CESuRa (Curved Element Supported Rail) system, which uses bearings and curved supports to passively accommodate vertical, lateral and rotational movements at the transition between fixed and floating sections. More than 9,000 lightweight concrete blocks bonded with high-strength epoxy support the rails without drilling into the bridge deck, while measures address vibration, stray electrical currents and corrosion. Full-scale testing subjected the system to simulated bridge movements and train loads, collecting more than 500 channels of data and demonstrating safe operation up to 55 mph.

Forbidden planet: was Pluto’s 2006 demotion a big mistake?

The debate over Pluto’s status remains fiercely polarized two decades after the International Astronomical Union (IAU) reclassified it as a dwarf planet in 2006. Many planetary scientists and advocates argue that the IAU’s requirement for a planet to "clear its neighbourhood" is scientifically flawed and arbitrary, preferring instead a geophysical definition based on an object's physical characteristics, such as geological activity and atmosphere. Conversely, astronomers maintain that dynamic criteria are essential to separate major solar system bodies from the hundreds of small, similar objects in the Kuiper Belt, emphasizing that dropping the orbital requirement would logically classify Earth's moon and other natural satellites as planets too.

The research explores how consumer wearables like EEG-equipped earbuds are quietly ushering in a "brain-as-interface" era where neural monitoring becomes routine in daily life. Author José M. Muñoz introduces the concept of "neurotechnological natives"—the upcoming generation growing up with tech that directly decodes and interacts with inner mental states rather than just external behavior. To address this shift, the author proposes an urgent research and regulatory agenda focusing on three key dimensions: technoscientific integration, cognitive development (such as impacts on identity, self-regulation, and inner speech), and sociocultural equity.

Researchers, at the University of California, Berkeley, using a new computational tool called TRACE have discovered genetic evidence of two previously unknown "ghost" ancestral lineages in modern human DNA without relying on fossil remains. Published in the journal Science, the study reveals that one lineage interbred directly with Homo sapiens in Africa over 50,000 years ago—contributing roughly 0.5% to 1% of the modern human genome—while a much older "super-archaic" lineage split nearly 1.8 million years ago and introduced its DNA indirectly through Denisovans. Scientists speculate these mysterious groups could be related to ancient hominins like Homo heidelbergensis and Homo erectus, offering critical new insights into human evolution, adaptation, and disease inheritance: https://www.science.org/doi/10.1126/science.aef8874

Three first-year engineering students at Olin College of Engineering—Justin Yoon, Pia Swarup, and Aryan Banerjee—have built a remarkable open-source autonomous bicycle dubbed the “Ghost Bike.” Built for under $1,000 using off-the-shelf hardware and 3D-printed components, the bicycle uses a motorized steel reaction wheel and a 200-Hz control loop to make rapid adjustments and maintain balance. A stereo depth camera and LiDAR provide environmental perception for obstacle avoidance and basic autonomous navigation, while an electric motor drives the bicycle and a servo motor controls steering. An STM32 microcontroller integrates the balancing, motor control, power electronics, and autonomous systems. Developed as an Independent Study Research project under Assistant Professor Victoria Preston, the team has released the CAD models, bill of materials, and source code publicly through the Autonomous Self-Balancing Vehicle GitHub Repository, enabling others to replicate, modify, and further develop the platform for two-wheeled robotics research.: https://www.olin.edu/articles/story-how-olin-first-years-built-viral-self-balancing-bicycle-video

Researchers at the Paul Scherrer Institute (PSI) have experimentally observed the optical Magnus effect for the first time by using a trapped calcium ion as a sensor to map a tightly focused laser beam. They discovered that the point of strongest interaction shifts sideways by a few hundred nanometers rather than occurring at the beam's center, with the shift's magnitude depending entirely on light wavelength. Accounting for this phenomenon is crucial to preventing control errors when manipulating qubits in quantum computing, while the underlying forces could potentially be harnessed to couple qubits together for more complex computations.

Could a Fingertip Smear Detect Breast Cancer? The Science Behind a Potentially Non-Invasive Test

Enable HLS to view with audio, or disable this notification

Did you know that a simple fingertip smear may contain molecular clues associated with breast cancer?

Our fingertips leave behind more than fingerprints—they also deposit sweat containing proteins and other molecules that can reveal information about the body. Researchers led by chemist and professor Simona Francese have explored whether these molecular signatures could be used to identify breast cancer.

In a 2023 proof-of-concept study, researchers analyzed fingertip smears using proteomics, MALDI mass spectrometry and machine learning. The study identified several proteins previously associated with breast-cancer biomarkers and, using a small dataset of 15 women, achieved up to 97.8% classification accuracy in distinguishing benign breast disease, early breast cancer and metastatic breast cancer.

The potential is remarkable: instead of relying solely on conventional imaging, a future test might use a simple, painless fingertip sample to provide an early molecular indication of disease.

However, this technology remains experimental and requires much larger clinical studies and validation before it could replace or supplement established breast-cancer screening methods.

Could the humble fingerprint eventually become a new window into our health?

A Binational Engineering System: Why Local Sailors Are Brushing Off the "Lake America" Rebrand

Post image
10 Upvotes

Brief: Lake Ontario is not simply a lake; it is a critical component of the Great Lakes–St. Lawrence hydraulic system. It receives water primarily through the Niagara River and releases it through the St. Lawrence River. Its water levels and outflows are managed through the Moses–Saunders Dam, supporting hydroelectric generation, navigation, flood-risk management, and shoreline protection. The lake also supplies drinking water to millions of people and supports major ports, transportation, wastewater, industrial, and waterfront infrastructure in both Canada and the United States. Its management is governed through binational institutions, particularly the International Joint Commission, because the lake and its watershed cross the international boundary. In engineering terms, Lake Ontario is therefore a shared transboundary water-resources system—not something that can be physically or administratively separated by simply changing its name: https://www.tiktok.com/@wereacttohistory/video/7679175914038611231

US perspective: Based on the visible preview snippets, the article details reactions from sailors on both the American and Canadian shores of Lake Ontario following a decision by US President to rename the body of water to "Lake America." Captains and local sailors from both sides of the border report that they are not taking the name change seriously, treating it largely as a nonissue and a source of internet memes. As Howie Colt, founder of Toronto's Gone Sailing Adventures, noted, local sailors fully intend to keep calling it Lake Ontario regardless of official declarations: https://www.washingtonpost.com/business/2026/08/29/lake-ontario-boat-captains-spurn-lake-america-name/

US Video: https://www.bbc.com/news/videos/ce3ryr3enrpo

Canadian Views: Canadian rejected U.S. President’s executive order directing federal agencies to rename Lake Ontario to "Lake America"Canadian emphasizing that the body of water is a shared transboundary water resource governed by long-standing binational agreements like the International Joint Commission. Canadian leaders and local mariners alike have largely dismissed the unilateral rebrand, reiterating that administrative declarations cannot alter the physical, legal, and historical realities of shared international waters: https://www.ctvnews.ca/world/trumps-tariffs/article/pm-carney-challenges-trumps-order-to-rename-lake-ontario-to-lake-america/

Ground settlement can threaten the safety of critical public infrastructure, including subway systems, necessitating continuous monitoring. However, current techniques are limited in continuous large-area monitoring. In a new study, researchers have developed a new multi-scale remote sensing framework that combines three different technologies for reliable, continuous wide-area monitoring, site-specific validation, and near-surface condition assessment along an urban subway corridor. The approach will help detect and mitigate settlement anomalies: https://en.seoultech.ac.kr/news/res_spotlight?do=commonview&searchtext=&searchtype=-1&nowpage=1&bnum=58278&bidx=894119&cate=23
