Deep biosphere has endured mountain-building and erosion over hundreds of millions of years‎

A new study reveals that microbial life deep within Earth has persisted and repeatedly flourished through hundreds of millions of years of mountain-building and erosion. By analyzing minerals, fluids and gases from a 2.3-kilometer-deep (1.4-mile-deep) borehole in central Sweden, researchers have uncovered episodic bursts of methane-producing life linked to major geological events that shaped Scandinavia. The paper is published in the journal Communications Earth & Environment.

The listening gap is real—how AI might help teachers bridge it‎

A Grade 4 teacher showed her class a video of children who walk miles barefoot to school. A hand shot up: "Why are you showing us AI slop? No way this is real."

'The Jungle Book' offers an unconventional tool for undergraduate economics education‎

Research in the International Journal of Pluralism and Economics Education argues that "The Jungle Book" can serve as an unconventional teaching tool for undergraduate economics, using the original stories by Rudyard Kipling as well as Disney film adaptations to introduce concepts ranging from scarcity and sustainability to happiness and development.

Weak hydrogen bonds dethrone copper as the most stable metal binder, opening a new path for metal selection‎

Copper has been knocked off the top of a stability ranking it had dominated for decades. Without altering the atoms directly bonded to the metal, a KAIST research team reversed the longstanding trend in which copper generally forms the most stable complexes by tuning only the weak hydrogen bonds in its surrounding environment. The findings, which appear in the Journal of the American Chemical Society, could open new avenues for selective metal separation and recognition, as well as catalyst design.

Inexpensive blue pigment enables efficient one-step conversion of carbon dioxide to methane‎

A common blue pigment could help turn carbon dioxide (CO₂) from an industrial waste product into a useful fuel. A joint research team led by Tohoku University's Advanced Institute for Materials Research (WPI-AIMR), in collaboration with Hokkaido University and startup AZUL Energy, has developed a catalyst that converts CO₂ directly into methane (CH₄) with high efficiency using copper phthalocyanine, an inexpensive and readily available blue pigment.

Ships, ice cores and krill surveys underpin Australia's 10-year Antarctic monitoring strategy‎

The important role ships play in gathering scientific data in Antarctica and the Southern Ocean has been outlined at a leading Antarctic science conference in Hobart. The biennial Australian Antarctic Research Conference was held at the University of Tasmania and attracted 400 researchers from around the globe.

How climate change may amplify the impact of earthquakes in the Arctic‎

Permafrost refers to permanently frozen ground. The rock is held together by ice, much like cement binds concrete. However, when the ice thaws, the ground becomes weak and unstable. During an earthquake, this can trigger a series of natural hazards. An international research team investigated precisely such an event.
