Alaska Science Forum time capsule: Stalwart perennials make a bet on the future each year - Anchorage Daily News

Note: At the start of every walk, my dogs try to sneak away to “fox town,” a fox den on the other side of the pond near my cabin, and we often see the adult foxes trotting through the neighborhood. Hearing one of them bark the other evening, I was reminded of this March 26, 2020, story by Ned Rozell. He recently reported that foxes still use the den, but did not occupy it in summer 2026. — Sara Wilbur One year ago, in a world with the same mountains and valleys but feeling very different, we made a discovery.

The Moon no longer generates a global magnetic field, but traces of its ancient magnetism remain locked inside lunar rocks and soil. By studying the magnetic minerals preserved in these materials, scientists can reconstruct how the Moon's magnetic environment changed over time. Researchers analyzing metallic iron inside impact glass from Chang'e-6 lunar soil have now identified face-centered cubic γ-Fe for the first time in natural lunar samples.

Mud from a fjord shows an Atlantic air pattern brought wetter, colder spells to southern Greenland, a clue to how its ice may fare. Greenland’s ice is shrinking as the planet warms. But in the island’s southwest, rainfall and snowfall have been influenced by the same North Atlantic air-pressure pattern for at least 5,000 years. When that pattern tipped one way, the region turned wetter and colder. The record comes from mud on the floor of a Greenland fjord, and it suggests snowfall, not only temperature, shaped how the area’s ice grew and shrank. It doesn’t yet show how glaciers there will respond to the warming ahead. Johan Faust, a researcher at MARUM, the Center for Marine Environmental Sciences at the University of Bremen in Germany, led the work with colleagues in Germany, Norway, Denmark and Canada. A seesaw in the airThe pattern is called the North Atlantic Oscillation. It’s the difference in air pressure between a low that sits near Iceland and a high near the Azores, and it’s strongest in winter. When that difference is large, the pattern is in its positive phase. Northwestern Europe and southwestern Greenland both get more rain and snow.

The Futura Team represents the pulse of Futura’s editorial department, bringing together a collective expertise dedicated to the dissemination of scientific knowledge. Rather than the work of a single author, every article published under this signature is the result of a rigorous collaborative process involving journalists, editors, and fact-checkers. Specializing in news analysis via desk research and international wire services, the team focuses on transforming raw information into accessible, verified content. This curation and synthesis process ensures constant monitoring of technological innovations and major scientific breakthroughs. By cross-referencing sources and conducting multiple rounds of peer review, the Futura Team guarantees scientific accuracy and pedagogical clarity. This collective signature serves as a hallmark of trust, providing reactive, cross-disciplinary information at the forefront of current events Normally, when an asteroid swings by Earth, the burning question is simple: “Are we at risk?” Should we prepare for a massive space rock to pancake our planet? Not this time.
