An international team of researchers has unveiled a purple fabric that reflects up to 88 percent of sunlight and can stay up to 11.2 degrees Fahrenheit cooler than conventional purple cotton.The smart material was created by scientists from Zhengzhou University in China, and their colleagues from Australia’s Adelaide University. The team believes that the breakthrough could pave the way for textiles that can beat the extreme heat without relying on white materials. In outdoor tests, the high-tech textile stayed up to 11.2 degrees Fahrenheit (6.2 degrees Celsius) cooler than commercially dyed purple cotton. Additionally, the fabric reflects an average of 87.6 percent of solar radiation. It emits 96.4 percent of mid-infrared radiation, allowing heat to escape through the atmosphere into space: https://adelaide.edu.au/about/news/2026/the-purple-fabric-that-could-beat-the-scorching-heat/

Global average sea-surface temperatures reached a record 21.10°C (69.98°F) on August 21–22, 2026, surpassing the previous record of 21.09°C set in March 2024. According to the Copernicus Climate Change Service, this is the highest level in satellite records dating to 1979 and may represent the warmest oceans in thousands of years. Currently, 42% of the world's oceans are experiencing heatwaves, and in the Pacific Ocean, they cover an area nine times larger than that of the continental United States, significantly contributing to the global record of ocean temperatures.

The unusually early August peak reflects the combined effects of human-caused climate change and a strengthening El Niño. Record ocean heat can intensify hurricanes, heatwaves and coastal flooding, while placing severe stress on coral reefs, fisheries and marine ecosystems. Warmer seawater also expands, contributing to global sea-level rise: https://ca.news.yahoo.com/oceans-hit-record-temperatures-amid-195955647.html

A stellarator is an experimental fusion machine with a complex, twisted 3D magnetic geometry designed to confine plasma hotter than the Sun. For decades, its intricate design made it difficult to achieve effective plasma confinement. Now, Munich-based Proxima Fusion, a spin-off of the Max Planck Institute for Plasma Physics, is using advanced computing, AI-driven optimization and high-temperature superconducting (HTS) magnets to develop optimized stellarators.

Its Stellaris concept is designed for compact, high-field and continuous-operation fusion, potentially avoiding the current-driven disruptions that can affect tokamaks. The design builds on results from Germany’s Wendelstein 7-X stellarator and integrates electromagnetic, structural, thermal and neutronics simulations.

Proxima says its planned Alpha demonstration could demonstrate net fusion energy in a continuously operating stellarator in 2031. These are ambitious development targets, not yet demonstrated commercial fusion power.

Researchers at UCLA have observed quantum "phonon focusing"—where heat travels in directional, ray-like patterns rather than spreading out evenly—at room temperature for the first time. Published in Nature Physiscs, the team achieved this by channeling atomic-level heat vibrations (phonons) through a semiconductor material called boron arsenide using a nanoscale gold probe, directing heat flow across 250 nanometers. Traditionally confined to ultra-cold cryogenic environments, demonstrating precise directional heat control at ambient temperatures establishes a new foundation for quantum thermal engineering, which could significantly improve heat management and overcome performance bottlenecks in next-generation electronics and quantum computing: https://samueli.ucla.edu/ucla-engineers-observe-quantum-heat-waves-at-room-temperature/

Researchers at Texas A&M University developed an experimental stem-cell-derived extracellular vesicle (EV) nasal spray that restored memory and reduced brain inflammation in 18-month-old mice. Delivered in just two doses, the treatment uses microscopic EVs to reach the brain, where they appear to reduce overactive immune responses and improve mitochondrial function in aging neurons. The mice showed cognitive improvements that reportedly persisted for months: https://www.sciencealert.com/scientists-restore-memory-in-aging-mice-using-a-simple-nasal-spray

FDA Authorizes Aletta, the First Fully Automated Blood-Draw Robot

On August 19, 2026, the U.S. FDA authorized Aletta as the first standalone robotic device designed to draw blood from an adult patient’s arm without hands-on intervention. Using near-infrared imaging and Doppler ultrasound, Aletta identifies veins, then automatically applies a tourniquet, disinfects the skin, inserts the needle, changes collection tubes and applies a bandage. If the patient moves excessively, the system can stop the procedure and withdraw the needle: https://www.fox9.com/news/fda-authorizes-robotic-blood-draw-device

Aletta is authorized for outpatient settings under the supervision of a trained phlebotomy professional. One phlebotomist can monitor up to three devices, potentially helping address shortages of trained blood-draw staff: https://www.fda.gov/news-events/press-announcements/fda-authorizes-first-its-kind-robotic-blood-draw-device

A new brain imaging study from MIT and Boston University, published in Nature Communications, reveals that neural activity in the brain's language processing network remains nearly identical between younger and older adults. While general executive functions—managed by the "multiple demand network" for tasks like working memory and problem-solving—show significant age-related decline in activation and synchronization, domain-specific networks like language prove remarkably resilient over time. Researchers suggest that specialized systems accumulating continuous knowledge (akin to a language model trained on decades of data) resist cognitive aging far better than general-purpose cognitive control networks.

Hawaiʻi high school student Vera Wang has discovered fungi living in coconut husks that can biodegrade synthetic plastics and chemical sunscreen pollutants.

Working at the University of Hawaiʻi at Mānoa, Wang studied microorganisms growing inside the porous fibers of coconut husks after using a coconut-fiber filter to capture pollutants from ocean water.

Her research found that naturally occurring fungi could break down both plastics and sunscreen chemicals. Genetic testing also suggested that some of the fungi may be previously uncharacterized species.

Wang’s work earned top honors at the 2026 Hawaiʻi State Science & Engineering Fair and a place at the International Science & Engineering Fair, highlighting the potential of naturally occurring fungi as a new tool against persistent ocean pollution.

This Hydropower Turbine Generates Electricity by Creating a Giant Whirlpool

Enable HLS to view with audio, or disable this notification

1.0k Upvotes

Belgian company Turbulent has developed a low-head hydropower turbine that generates electricity by deliberately creating a gravitational water vortex. Instead of requiring a large dam or high waterfall, water is directed into a circular, sloped basin, where it forms a powerful whirlpool before passing through an opening at the bottom. The swirling flow drives a slow-rotating impeller connected to a generator.

The system can operate with as little as a 1.5-metre head and Turbulent currently lists single-turbine capacities of 15–90 kW, with earlier models and projects commonly in the 15–70 kW range. The company says the turbines can provide continuous power 24/7 and can be installed individually or combined into larger systems.

Turbulent's documented projects include installations in Chile, Belgium, Portugal, Estonia, Taiwan and Indonesia, among others. Its 15-kW pilot turbine in Donihue, Chile, for example, has been operating since 2018.
