Study finds basalt could cut cement CO2 emissions by over 80 percent using existing production tech

Study finds basalt could cut cement CO2 emissions by over 80 percent using existing production tech

A new study argues the cement industry could dramatically cut emissions by switching raw materials. Instead of limestone, scientists propose using carbon-free, calcium-rich silicate rocks like basalt. Because limestone must be heated above 1,500°C—releasing large amounts of CO2—basalt-based production could cut emissions by more than 80% in theory, and by over 25% even with today’s fossil-fuel-heavy energy. The research also suggests existing technologies could enable the change, producing standard Portland cement.

Pink rocks in Antarctica uncover a hidden granite giant beneath Pine Island Glacier

Pink rocks in Antarctica uncover a hidden granite giant beneath Pine Island Glacier

Bright pink granite boulders on Antarctica’s Hudson Mountains were the clue to something far larger beneath the ice. Using aerial gravity mapping and geology analysis, researchers found a massive granite formation about 100 kilometers wide and 7 kilometers deep under the Pine Island Glacier. The result could refine understanding of Antarctic geology and how this glacier influences sea level projections.

Scientists map a giant freshwater lake under Utah’s Great Salt Lake and upend expectations for the basin

Scientists map a giant freshwater lake under Utah’s Great Salt Lake and upend expectations for the basin

A new study using airborne electromagnetics and satellite imagery reveals a vast underground freshwater system extending kilometers beneath Utah’s Great Salt Lake. The discovery challenges the belief that the basin’s extreme salinity dominates underground conditions. Researchers say the hidden water could reshape approaches to managing exposed sediment and related air pollution, but experts warn against careless pumping that could trigger unintended environmental effects.

Texas Heat Makes Snakes Change Their Timing Every Day

Texas Heat Makes Snakes Change Their Timing Every Day

Snakes don’t keep a fixed timetable—temperature does. In Texas-like heat, they’re more active in the evening, while cooler conditions push daytime movement. Researchers say their behavior follows environmental cues rather than an internal clock, which is why sightings can feel random. Knowing this shift can better explain when encounters are most likely.

WMO says ozone layer is healing fast and could hit 1980s levels by mid century

A new WMO report says the Earth’s ozone layer is on a clear recovery path, projected to return to 1980s levels by mid-century. The shift is attributed to the Montreal Protocol, which curbed ozone-depleting substances. Early signs show up in a smaller 2024 Antarctic ozone hole, but scientists warn that long-term monitoring is still essential for full healing.
