Ancient Crater Lakes Rewrite Saharan Climate History, And Possibly Civilization’s Origins
The findings suggest the Sahara had an extra source of rain that kept part of it habitable until surprisingly recently.
Carbon nanotube ‘smart windows’ offer energy savings by modulating near-infrared light transmission
Half of the sun’s radiant energy falls outside of the visible spectrum. On a cold day, this extra infrared light provides additional warmth to residential and commercial buildings. On a warm day, it leads to unwanted heating that must be dealt with through energy-intensive climate control methods such as air-conditioning.
Why the US power grid upgrade could top $1 trillion
Aging infrastructure, soaring electricity demand, renewable integration, and climate risks are driving the largest US grid modernization effort in history.
Scientists explore real-time tsunami warning system on world’s fastest supercomputer
Scientists at Lawrence Livermore National Laboratory (LLNL) have helped develop an advanced, real-time tsunami forecasting system—powered by El Capitan, the world’s fastest supercomputer—that could dramatically improve early warning capabilities for coastal communities near earthquake zones.
The exascale El Capitan, which has a theoretical peak performance of 2.79 quintillion calculations per second, was developed at the National Nuclear Security Administration (NNSA). As described in a preprint paper selected as a finalist for the 2025 ACM Gordon Bell Prize, researchers at LLNL harnessed the machine’s full computing power in a one-time, offline precomputation step, prior to the system’s transition to classified national-security work. The goal: to generate an immense library of physics-based simulations, linking earthquake-induced seafloor motion to resulting tsunami waves.
The paper is published on the arXiv preprint server.
SpaceX’s Mars Breakthrough — What No One’s Talking About!
