Different interannual co-evolutionary models reveal how East Asia's jet stream and summer monsoon evolve together

Phys.org: Earth science - Fri, 04/17/2026 - 01:20

The East Asian Subtropical Westerly Jet (EASWJ) and the East Asian Summer Monsoon (EASM) are two pivotal components of the East Asian monsoon system, shaping the precipitation distribution and climate over East Asia. Whether the co-evolutionary EASWJ–EASM relationship remains consistent under different climatic backgrounds has been a key question in both modern and paleoclimate research.

Relocating Venice among the options explored to protect the city against sea-level rise

Phys.org: Earth science - Thu, 04/16/2026 - 23:00

Relocating the city of Venice is among four potential options—including movable barriers, ring dikes and closing the Venetian Lagoon—that could help it adapt to future sea-level rise over the next 200 years, according to a new study.

Novel technique drills more detail into ice core records

Phys.org: Earth science - Thu, 04/16/2026 - 22:30

Glaciers can reveal vast archives of information about Earth's environmental past, but deciphering the origins of the matter within them can be a challenge. Now, using a novel technique that enables researchers to directly analyze millions of individual particles at once, a new study has revealed that specks of dust trapped in Antarctic ice likely originated from a common source during the last Ice Age, between about 120,000 and 11,500 years ago.

Extensive faults beneath Nevada nuclear lab raise unanswered earthquake risks

Phys.org: Earth science - Thu, 04/16/2026 - 21:20

The underground laboratory in Nevada where the U.S. conducts nuclear subcritical experiments is riddled with faults. Researchers have not confirmed whether any of these faults are active and could rupture during an earthquake, according to a presentation by members of the Defense Nuclear Facilities Safety Board delivered at the 2026 SSA Annual Meeting.

LiDAR maps medieval castle terrain and flags landslide-prone slopes in Japan

Phys.org: Earth science - Thu, 04/16/2026 - 21:00

Researchers at University of Tsukuba have developed a method to differentiate the topography of medieval mountain castles from that of natural ridges using airborne light detection and ranging (LiDAR) data. This method is expected to be useful for detecting historically modified terrain, such as archaeological sites in mountainous regions, as well as for assessing the extent of topographic modifications and estimating the potential risk of landslides on modified slopes.

Navigating the past with ancient stone compass needles

Phys.org: Earth science - Thu, 04/16/2026 - 19:20

Magnetic rocks with iron oxide concentrations act as natural chroniclers of Earth's past continental movements. Using small samples of rocks, scientists can isolate magnetic grains that were frozen in orientation as the rock solidified. The magnetization of these grains acts as a miniature compass needle, pointing toward ancient magnetic poles. This same principle applies to extraterrestrial samples, such as meteorites and lunar rocks, which preserve evidence of the early solar nebula's evolution.
