Scientists report a species of Arctic shark reaching about 400 years old. Analysis suggests DNA repair pathways keep its eyes functional for centuries, offering potential insights into longevity and ocular preservation.

Understanding how rising temperatures affect the immune resilience of endangered Arctic charr informs conservation and fishery management in a warming Arctic ecosystem. In Finland, these fish are farmed mainly to stock wild populations.

A photographer aboard a ship in Scoresby Sund captured a rare total solar eclipse over the high‑arctic fjords, showcasing dramatic lighting shifts against the stunning Arctic landscape.

New research from Simon Fraser University indicates Arctic landscapes are eroding faster than previously estimated, largely due to climate change.

A scientific study sampled snow microinvertebrates across lowland, high‑mountain, and Arctic sites—including Spitsbergen (Svalbard) and the Tatra Mountains—to assess ecological differences among these environments.

Scientists examined a jar of ash collected from the 1992 Mount Spurr eruption, revealing that the particles are fragments of plagioclase glass coated with fine tephra and formed by explosive fragmentation of near‑solid magma driven by gas pressure.

Canada’s new Ice Dart drone is designed to overcome harsh Arctic conditions such as ice, wind, and steep terrain, enabling more reliable landing and data collection in the region.

The new tool converts satellite‑derived ice measurements into realistic underwater acoustic models, improving accuracy of jamming simulations to aid Arctic operational planning and secure communications.

Scientists have introduced a new adaptive multimodal fusion network that enables fine‑grained analysis of Arctic sea ice. By integrating diverse data sources, the tool improves tracking of how sea ice regulates global heat, carbon, and freshwater.

Canada’s new defense spending plans would deploy technology to detect whales and submarines in Arctic waters, offering northern communities enhanced surveillance and environmental monitoring as part of a broader focus on Arctic sovereignty.

The research demonstrates that externally forced Arctic warming is amplified about three times, yet internal climatic variability obscures this signal, creating uncertainty in future temperature projections and complicating climate model predictions.

Florida researchers are investigating whether a notorious Arctic plant is truly harmful, aiming to revise its reputation and inform conservation decisions for the region's fragile ecosystems.

The reply emphasizes that contemporary climate models attribute Arctic amplification primarily to temperature feedbacks.

Smoke from large wildfires in North America, Eurasia, and Indonesia has spread across the Northern Hemisphere, reaching the Arctic and influencing its environmental conditions.

India is set to boost its Arctic research budget and turn its seasonal winter expedition into an annual program, underscoring a heightened focus on polar science.

A NASA study has uncovered a previously unrecognized phase of Arctic freeze in which the zero‑curtain effect prolongs moisture availability for soil microbes, potentially increasing carbon release from tundra ecosystems.

NOAA is withdrawing from producing the Arctic Report Card, a key environmental monitoring tool for Alaska and national stakeholders, prompting scientists to keep the information flow going.

Archaeological work at the Zhokhov site in East Siberia uncovered the earliest concrete evidence of sled dogs and long‑range land transport, dating to roughly 9,000 years ago. These findings illuminate how ancient peoples moved across the high Arctic landscape.

Scientists used 3D X‑ray imaging to examine the spiral tusks of narwhals that can reach about 5 m in length. The study focuses on individuals living primarily off Canada, Greenland and Norway’s Arctic waters.

The expedition team reports few active melt ponds on the sea ice while heading northward in the 2026 Arctic Ocean journey, contrary to expectations of widespread melting.

A new analysis compares GNSS-derived sea ice drift patterns in the Arctic's Beaufort Gyre and Transpolar Drift with eight Antarctic data sources, covering 2017–2024.
