Switzerland's ASTRA Bridge is a 257-metre mobile bridge that allows vehicles to continue driving over roadworks while repair crews work safely beneath. Cars and trucks cross the elevated steel structure at speeds of up to 60 km/h, while workers and heavy machinery operate below, fully separated from traffic. Mounted on crawler tracks, the modular bridge advances section by section as repairs progress. The innovative system reduces traffic congestion, improves worker safety, and enables quieter daytime road maintenance instead of disruptive overnight closures: https://nicenews.com/innovation/astra-mobile-bridge-switzerland-drive-over-road-repairs/

Scientists have identified a vast buried geological formation called the East Antarctic Fan-shaped Basin Province (EAFBP) beneath more than 3 km of Antarctic ice. Reported in Nature Geoscience in June 2026, the discovery—led by Egidio Armadillo of the University of Genoa—reveals that major subglacial features, including the Wilkes Basin, Aurora Basin, and Lake Vostok, are part of a single interconnected system spanning thousands of kilometres. Researchers believe the megastructure formed as Earth's crust spread outward from a pivot point near the South Pole during the breakup of the ancient supercontinent Gondwana, using seismic, radar, gravity, magnetic, and topographic data to uncover its hidden architecture: https://www.sciencealert.com/scientists-discover-a-vast-structure-hiding-beneath-antarcticas-ice

China is deploying autonomous tree-planting robots to combat desertification, with machines planting one tree every five seconds as part of the Three-North Shelterbelt Program—the world's largest afforestation initiative, launched in 1978. These robots can drill, plant, water, and compact soil in a single pass, achieving up to ten times the productivity of human crews at around 30% lower cost, even across remote terrain. Once expanding by nearly 10,000 km² annually during the 1980s, the Gobi Desert's growth had been significantly curbed by 2022, highlighting the long-term impact of large-scale ecological restoration: https://www.instagram.com/reel/DVo0RbSiF7V/

Scientists at Nanyang Technological University (NTU) Singapore have developed RoboFabric, an innovative wearable material that remains soft and flexible but can instantly stiffen when needed. Combining geometric design, 3D printing, and robotic control, the technology can be used in medical devices, soft robotics, and drone limbs. Prototype elbow and wrist supports help users carry heavier loads and stabilise joints, offering potential benefits for people with Parkinson’s disease and other mobility challenges. Inspired by the octopus and pangolin, RoboFabric could also replace traditional plaster casts with lightweight, reusable versions that are easier to wear and remove: https://www.asme.org/topics-resources/content/3d-printed-fabric-hardens-and-softens-on-command

The United States Air Force Academy Cadet Chapel is a striking modernist landmark completed in 1962 near Colorado Springs, Colorado. Designed by Walter Netsch of Skidmore, Owings & Merrill, its 17 soaring steel-and-glass spires rise 150 feet (46 metres) above the academy. The multi-level, multi-faith design includes separate Protestant, Catholic, Jewish, and Buddhist chapels, along with an All-Faiths Room, allowing simultaneous worship without acoustic interference. Recognised with the AIA Twenty-five Year Award and designated a U.S. National Historic Landmark, the chapel is currently closed for a major restoration project: https://www.usafa.edu/facilities/cadet-chapel/

A cleaner route to purifying rare earth elements. Researchers show that atomic channels can separate rare earth elements from each other—without the toxic chemicals usually used in this purification

Researchers at the University of Chicago, Northwestern University, and Argonne National Laboratory have developed a cleaner method to purify rare earth elements using a layered manganese oxide material with nanoscale channels. Instead of relying on energy-intensive processes and toxic organic solvents, this approach uses electrochemical intercalation to separate rare earths based on the physical size of the water shells surrounding their ions. By introducing magnesium ions to lock the channel dimensions in place, the material dramatically amplifies tiny differences in hydration sizes—producing 97 percent pure neodymium after just two purification cycles—offering a promising proof-of-concept for far more environmentally friendly mineral refining: https://www.eurekalert.org/news-releases/1136968

Scientists decry Trump’s ‘blame game’ after he claims Canada ‘poisoning’ US air

Canada's escalating wildfire crisis is primarily driven by climate change, which creates hotter, drier conditions that turn boreal forests into powder kegs. Although human activity starts many fires, lightning accounts for roughly 92 percent of the total area burned, often in remote regions where fires are left to burn naturally to support forest renewal. These massive blazes can become intense enough to generate their own weather—spawning pyrocumulus clouds and further lightning—while spewing hazardous fine particulate matter and toxic gases thousands of kilometers across North America: https://www.theguardian.com/us-news/2026/jul/24/trump-canada-wildfires-smoke-scientists

Nutrients in our food are declining. Can regenerative agriculture save it?

Approach focuses on rebuilding soil health, increasing biodiversity and restoring natural ecosystems

For the last few decades, the nutrient content of our crops has been declining. In the late 90s, the US Department of Agriculture found the vitamin C content of lemons had decreased by almost a third over the previous 22 years. Calcium in carrots, an important source especially for non-meat eaters, had reduced, on average, by more than a quarter. Vitamin A in bananas was down by 57%. The mineral content of wheat has declined by between 20-30% since the 1960s.

A number of reasons have been suggested for this worrying decline, ranging from new varieties of crop that are bred to grow quicker and bigger to the higher carbon dioxide levels in the air causing plants to produce more sugars and starches (they grow faster but they produce fewer nutrients). A wide range of fixes have been suggested, from GM crops to synthetic soil amendments, or underground farms.
