Believe it or not, NASA is actually using lasers to conduct 3D wind measurements. More specifically, the advanced 3D Doppler wind LiDAR instrument called the Aerosol Wind Profiler (AWP) to measure wind speed and direction.
Yes, it’s true that Tesla is building a special factory for its Tesla Semi, an all-electric Class 8 truck. The factory is going up near Giga Nevada in Sparks, Nevada, right next to Tesla’s current Gigafactory. This strategic spot uses the setup and resources Tesla already has for making batteries and vehicles.

The Hubble Space Telescope, run by NASA and ESA, took a striking picture of the odd-looking spiral galaxy NGC 1961, also called Arp 184, sitting 191 million light-years away in the Camelopardalis constellation. Why’s it so strange? It’s a mix between barred and unbarred spiral galaxies, with a faint or missing central bar of stars.
Mercedes-Benz is currently developing a photovoltaic coating, described as a “solar paint,” that can be applied to a vehicle’s exterior like a thin layer of paste. This isn’t your typical paint—it’s packed with solar modules that capture sunlight and convert it into electricity to power an EV.
There are metal 3D printers, and then eufyMake’s UV Printer E1, the world’s first 3D-texture UV printer. What does this mean? It uses UV-curable ink that hardens instantly under ultraviolet light, allowing it to print vibrant, full-color designs with tactile 3D textures up to 5mm high on a wide variety of surfaces.
A massive power outage struck Spain and Portugal today, April 28, 2025, affecting millions across the Iberian Peninsula, including major cities like Madrid, Barcelona, Lisbon, and Seville. The blackout began around 12:30 p.m. local time, plunging much of the region into darkness and disrupting critical infrastructure, such as transport, both train and aircraft.
It’s true, the SonarPen for USB Type-C can turn your MacBook’s trackpad into a drawing pad, which can save you a bundle compared to dedicated devices. How does it work? You download the free SonarPen Driver for macOS, plug in the SonarPen, and calibrate it. The trackpad becomes a pressure-sensitive drawing surface.
KUXIU S2 is a 5000mAh MagSafe-compatible power bank that’s been marketed as the “world’s first” to use a semi-solid-state battery. What sets it apart from standard power banks? They reduce fire risk compared to lithium-ion batteries with flammable liquid electrolytes. Kuxiu says the S2 still works even after durability tests like being punctured, dropped, or exposed to fire.
