Running ARM Chips On Algae Power

Running ARM Chips On Algae Power

How big is an AA battery and can run an ARM Cortex M0+ for six months? Well…probably an AA battery, but obviously that wouldn’t be worth mentioning. But Cambridge researchers have built a blue-green algae cell that can do the job. As you might expect, algae need light because they generate energy through photosynthesis. However, … Read more

Invisible Walls In Space May Explain a Problem That Has Been Perplexing Scientists

Invisible Walls In Space May Explain a Problem That Has Been Perplexing Scientists

One of the biggest challenges to our traditional understanding of the cosmos is the so-called “satellite disk problem.” Essentially, scientists are confused because smaller galaxies orbit larger galaxies in thin, flat planes rather than the more disordered orbits one would expect with the Lambda model of cold dark matter (ΛCDM) – the “incredibly successful paradigm” … Read more

Total lunar eclipse: the moon will appear to turn red for many lucky earthlings

Total lunar eclipse: the moon will appear to turn red for many lucky earthlings

Many earthlings will be able to see the Moon briefly turn red on Sunday. The event will mark the first total lunar eclipse this year. The rare visual is caused by the Moon passing through Earth’s shadow, blocking much of the Sun’s light from reaching our nearest neighbor. “The wonderful thing is that when the … Read more

Massive Hunga Volcano Eruption Created an Atmospheric Pulse That Caused an Unusual Tsunami-Like Disturbance

Hunga Tonga Erupts

This looping video shows a series of GOES-17 satellite images that captured an umbrella cloud generated by the submarine eruption of the Hunga Tonga-Hunga Ha’apai volcano on January 15, 2022. Arcing shock waves shaped of crescent and many flashes are also visible. Credit: NASA Earth Observatory image by Joshua Stevens using GOES imagery courtesy of … Read more
