NASA's Ingenuity Mars Helicopter Completes First Flight With New Navigation Software

This illustration depicts Mars Helicopter Ingenuity during a test flight on Mars. Ingenuity was taken to the Red Planet strapped to the belly of the Perseverance rover (seen in the background). Ingenuity, a technology experiment, was the first aircraft to attempt controlled flight on another planet. Credit: NASA/JPL-Caltech Compared to some of the other flights … Read more

Humans and octopuses descended from SAME animal that lived 518 million years ago

Octopuses possess a variety of gene regulators called microRNAs (miRNAs) in their neural tissue compared with the number in vertebrates, which means their brains are similar to humans.  This could explain their high intelligence

Octopuses and humans descended from the same primitive worm-like animal that lived 518 million years ago, and this could be why the eight-limbed creatures are highly intelligent. The creature, known as Facivermis yunnanicus, is the earliest known example of animals evolving to lose body parts it no longer needed and was minimally intelligent. A new … Read more

What if the dinosaurs hadn’t gone extinct? Why our world might look very different

What if the dinosaurs hadn't gone extinct?  Why our world might look very different

Giant dinosaurs and mammals through time. Credit: Nick Longrich Sixty-six million years ago, an asteroid hit the Earth with the force of 10 billion atomic bombs and changed the course of evolution. Tea skies darkened and plants stopped photosynthesis. The plants died, then the animals that fed on them. The food chain collapsed. Over 90% … Read more

Bright light from black holes caused by particle shock waves • The Register

Scientists have reported a “huge leap forward” in the understanding of light and other electromagnetic radiation emitted by black holes using NASA’s newly deployed $188m space telescope IXPE. Beams of electrons smash into slower-moving particles causing a shock wave which results in electromagnetic radiation across frequency bands from X-rays to visible light, according to a … Read more

We Finally Know How Black Holes Produce The Most Brilliant Light in The Universe : ScienceAlert

For something that emits no light that we can detect, black holes just love to cloak themselves in radiance. Some of the brightest light in the Universe comes from supermassive black holes, in fact. Well, not actually the black holes themselves; it’s the material around them as they actively slurp down vast amounts of matter … Read more
