The best hydrogen for heavy-duty transport is locally produced and green, say researchers

If trucks ran on hydrogen instead of fossil fuels, carbon dioxide emissions from heavy-duty road transport could be significantly reduced. At the same time, a new study from Chalmers University of Technology in Sweden shows that differences in how the gas is produced, distributed and used greatly affect its climate benefits.

Locally produced green hydrogen is the best option for the climate—with the additional benefit of enabling all countries to become self-sufficient in energy and fuel, even in times of crisis and war.

Heavy-duty road transport currently accounts for one fifth of global oil consumption and, in the EU, heavy-duty diesel trucks are the largest source of emissions of the transport-related greenhouse gas carbon dioxide. In the future, the need for road transport is expected to increase, and consequently also the sector’s demand for fossil fuels from oil.

These Alien-Looking Fossils May Explain the Origins of Complex Life

In the fossil record, creatures without hard shells or skeletons, such as jellyfish, are rarely preserved for long periods of time. Preservation is even less likely in sandstone, a rock made of coarse grains that is full of pores and typically forms in environments shaped by strong waves and frequent storms. Despite these challenges, fossils dating to about 570 million years ago tell a very different story. During the Ediacaran period, unusual soft-bodied organisms died on the seafloor, were quickly buried by sand, and were preserved with striking detail.

These remarkable fossils have since been discovered in rock formations across the globe. Researchers are working to understand how the Ediacara Biota could be preserved so clearly, especially as impressions in sandstone, a process rarely seen elsewhere in the fossil record. Solving this puzzle could help clarify a major missing chapter in the history of large, visible life on Earth.

“The Ediacara Biota look totally bizarre in their appearance. Some of them have triradial symmetry, some have spiraling arms, some have fractal patterning,” says Dr. Lidya Tarhan, a paleontologist at Yale University. “It’s really hard when you first look at them to figure out where to place them in the tree of life.”

This Script Lets You Remove Built-In Windows 11’s AI Features

Windows 11 has been pushing AI features harder than ever over the past year, and there’s no sign of that slowing down anytime soon. From Copilot sitting in your taskbar to Recall capturing your screen, Microsoft’s AI is becoming impossible to ignore, and often impossible to remove.

If you value your privacy or just prefer a cleaner OS, a PowerShell script called Remove Windows AI is now available on GitHub. It was released by developer Zoicware and does exactly what it promises: it targets Copilot, Recall, Windows Studio Effects, and other related background services that run by default.

The script is actively maintained to ensure it can remove newly added AI components as they appear. If you find an AI feature or registry key that the script doesn’t remove, report it with details so the developer can add it in a future update.
