Researchers have developed a volcanic rock formula that cuts carbon emissions by 67%, potentially offering an affordable alternative to increasingly scarce cement additives.
Tech Xplore / New AI video tool removes objects without breaking the laws of physics
When movie and TV directors want to tinker with their footage in post-production, they have an array of tools at their disposal to perfect a scene if it wasn't shot exactly how they liked. That includes removing objects like ...
Phys.org / AMOC collapse could turn Southern Ocean into carbon source, adding 0.2°C to global warming
A shutdown of the Atlantic Meridional Overturning Circulation (AMOC) could trigger a substantial release of stored ocean carbon into the atmosphere over hundreds of years, according to a new study that simulated such a collapse ...
Phys.org / DNA evidence reveals a Stone Age population collapse in France
By analyzing DNA of ancient skeletons at a Neolithic burial site near Paris, an international team of researchers has uncovered evidence of a dramatic population replacement 5,000 years ago. The findings indicate that the ...
