RMIT researchers mixed cigarette-butt waste into fired-clay bricks and found that a 1% mixture retained useful strength, cut firing energy by about 10% and reduced thermal conductivity by 17%, while firing immobilised much of the waste’s heavy metals. At 5% butt content, estimated energy savings reached 58%, although the bricks became considerably weaker—and about 4.5 trillion cigarette butts are improperly discarded worldwide each year.
18+ hour, 59+ min ago (1259+ words) At one percent cigarette-butt waste, RMIT's lab bricks kept substantial compressive strength while using about a tenth less firing energy. Higher loadings brought much larger trade-offs. By Lab Report · Edited by Lachlan Brown Published September 13, 2026 · How we edit A discarded…...
Sweden imported nearly three million tonnes of other countries’ garbage in a single year and was paid roughly 373 kronor for every tonne it accepted — because its waste-to-energy plants burn what others throw away to help heat more than a million homes

An ROV survey in October 2024 under a tuna ranch off north-east Malta counted an estimated 100 to 150 common eagle rays — the largest known aggregation of Myliobatis aquila, apparently feeding on leftover baitfish
5+ day, 2+ hour ago (174+ words) Industrial aquaculture creates unexpected wildlife magnets, drawing massive gatherings of rays to feed on the scraps of farmed fish operations.

Don't pretend to be someone you're not: the measurable cost of a false front, and where the line falls
6+ day, 9+ hour ago (60+ words) Authenticity isn't just nice to have—sustained pretending depletes your mental resources in measurable ways, but knowing when to hold back matters just as much.

Don't waste a crisis: the psychology of why disruption is a real, and short, window for change
6+ day, 11+ hour ago (65+ words) Never let a good crisis go to waste is usually said with a cynical wink, the slogan of politicians and executives who see an emergency as cover for whatever they wanted to do anyway. By Science Blog Editorial Team Published…...
Four hippos brought to Colombia in 1981 have multiplied into nearly 200 animals roaming the Magdalena River basin — the world’s largest invasive animal, spreading through warm rivers with abundant food and few natural checks
1+ week, 8+ hour ago (252+ words) Published September 7, 2026 · How we edit A sign beside a cattle pond in central Colombia warns visitors that the water belongs to the most dangerous animal on earth and that they should stay out of it. The sign is accurate. It…...
Namibia's capital has been drinking its own sewage since 1968, when eight years of pilot work produced a system whose current plant pushes 21,000 cubic meters a day through a ten-step treatment process before the water reaches a kitchen tap again.
1+ week, 1+ day ago (542+ words) When a desert city runs dry, recycling sewage into tap water stops being taboo and becomes survival—a technology now copied worldwide but perfected first in Windhoek over fifty years ago. By The Long View · Edited by Mal James Published…...
Farmers in Thailand were losing crops to hungry elephants, so they began replacing sugar cane and bananas with coffee — a crop the herds largely leave alone, allowing farmers to protect their income without fencing the animals out

The Netherlands dredged 30 million cubic metres of sand, clay and silt from the bottom of a shallow lake and shaped it into 5 low islands; by 2020, a gull-billed tern chick had hatched there, after only one Dutch breeding case had been recorded since 1958
1+ week, 4+ day ago (557+ words) Engineers in the Netherlands took fine mud choking a lifeless lake and used it to build five low islands and within a few years, rare birds started showing up. Published September 3, 2026 · How we edit We are not ornithologists or ecologists,…...
Australia’s highest mountain rises just 2,228 metres—less than half the height of Mont Blanc—yet cold fronts sweeping north from the Southern Ocean can still build snowpacks approaching two metres in the Australian Alps during strong seasons.
1+ week, 5+ day ago (1608+ words) Spencers Creek’s long record shows how repeated cold, moist systems can build a metre-scale natural snowpack below Kosciuszko’s summit, even as Australian alpine snow declines over the long term.
