In 2026, researchers turned water-treatment waste into a filter for microplastics; real-water tests removed 86.9% to 97.1% of the particles

Santanu3 days ago05 mins

Representative Image (AI-generated) Microplastics are now found across aquatic environments, creating a difficult challenge for water-treatment systems that must remove tiny plastic particles without generating more waste. A new approach investigated in 2026 takes an unusual route: instead of treating water-treatment waste as something that simply needs to be discarded, researchers turned it into a…

Archaeologists were excavating a Roman cemetery in Poland when they found a much older man buried with two decapitated human heads, 42 animal teeth and a battle axe

Ancient Polish burial reveals man with 2 skulls, 42-tooth necklace and battle axe (Image Credit: X/ @sputnik_brasil) Archaeologists investigating a Roman-period cemetery in Poland made an unexpected discovery when they came across a burial that was thousands of years older than the surrounding graves. Instead of a Roman-era burial, they found the nearly complete skeleton…

Australia brought digging mammals back to an 8,000-hectare sanctuary; 8 years later, scientists found they had reshaped underground insect communities |

Image Credit: Brad Leue/AWC Australia’s effort to bring digging mammals back to an 8,000-hectare wildlife sanctuary has produced changes below the surface. Researchers studying Scotia Sanctuary in south-eastern Australia found that 8 years after reintroduced mammals were given access to areas, the communities of insects emerging from the soil had changed. The mammals, including greater…

Not just Nepal: How climate change puts European Alps under threat of glacial retreat and rock fall

Tourists look at the Mont-Blanc massif mountains and the ‘Mer de Glace’ glacier at the Montenvers station in Chamonix, France (Photo: AP). Climate change is increasingly becoming a threat to the snow-clad European Alps, amid initial investigations associating the August 26 Nepal tragedy with rising temperatures.Average temperatures in July, on the Aiguille du Midi peak,…

Nepal’s farmers built terraces into steep Himalayan slopes; now growing macaque populations are making it harder to keep their harvests |

Santanu3 days ago06 mins

Nepal’s mid-hills are places where farming has long meant working with the landscape rather than against it. Terraces cut into steep slopes turn difficult ground into fields for maize, millet, rice and other crops, with generations of farmers maintaining the walls and soil that make cultivation possible. But the balance between people, farmland and wildlife…

Scientists found an unexpected second product while making cleaner hydrogen; the leftover material was high-quality graphite |

Liquid hydrogen Tank at NASA Kennedy Space Center. Image Credit: US Department of Energy Scientists working on a cleaner way to produce hydrogen have discovered an unexpected second product which is high-quality graphite. The finding emerged from research into methane pyrolysis, a process that splits methane into hydrogen and solid carbon instead of producing CO2…

In 2014, Mexico began a massive 1 million-hectare restoration drive; 4 years later plant survival had risen from just 33% to 64% |

Santanu3 days ago05 mins

Restoring damaged land can look straightforward on paper: plant trees, repair soils and wait for vegetation to return. On the ground, the work is less predictable. Young plants have to survive drought, poor soils, fire, grazing and the other pressures that caused landscapes to deteriorate in the first place.Mexico’s National Forestry Commission, known as CONAFOR,…

In 2024, four Klamath River dams came down, reopening habitat blocked for over a century; in two salmon runs, 21,052 Chinook moved upstream and reclaimed 88% of their historic range

Santanu3 days ago07 mins

Four concrete barriers blocked the way for salmon that once swam freely between the Pacific Ocean and the high desert reaches of Oregon and California for more than a hundred years. The dams were removed in 2024 as part of one of the largest dam removal projects in U.S. history, letting the river flow freely…

After losing about 140.5 billion tons of ice a year for two decades, Antarctica temporarily reversed course, gaining a record 695 billion tons in 2021-23 as tropical warmth drove heavy snowfall

Santanu3 days ago03 mins

Representative Image (AI-generated) Antarctica has been losing mass for years as glaciers shed ice into the ocean, contributing to rising sea levels. But between 2021 and 2023, the continent experienced an unusual and temporary reversal. Instead of continuing to lose mass at its recent rate, Antarctica gained about 695 billion tonnes over 22 months, marking…

Princeton put AI in charge of a fusion-plasma control loop running every 20 milliseconds; in one test it predicted a damaging instability 200 ms early and stopped it before it began
