For more than 250 years, mathematicians have wondered if the Euler equations might sometimes fail to describe a fluid’s flow. A new computer-assisted proof marks a major breakthrough in that quest.
The renowned physicist and science communicator, Brian Cox delves into the topic of alien life and in particular, the question about intelligent alien civilization.
With his trademark enthusiasm and engaging style, Brian Cox explores the possibility of extraterrestrial life and why we haven’t found any.
The video starts with a brief overview of what Brian Cox & astronomers call: “The Great Silence”. Cox then goes on to explain the Fermi Paradox and the Dark Forest Hypothesis, which suggest that intelligent life may be intentionally avoiding contact with other civilizations to avoid being destroyed.
Cox uses his expertise in physics and astronomy to explain how alien life may be closer than we think. Like on the surface of the red planet, Mars. He discusses the potential for life to exist in other planets because there are at least 20 billion other earth like planets in our galaxy alone.
Throughout the video, Cox provides easy-to-understand explanations, making complex scientific concepts accessible to a broad audience.
Despite AI’s impressive track record, its computational power pales in comparison with that of the human brain. Scientists today unveil a revolutionary path to drive computing forward: organoid intelligence (OI), where lab-grown brain organoids serve as biological hardware. “This new field of biocomputing promises unprecedented advances in computing speed, processing power, data efficiency, and storage capabilities – all with lower energy needs,” say the authors in an article published in Frontiers in Science.
Artificial intelligence (AI) has long been inspired by the human brain. This approach proved highly successful: AI boasts impressive achievements – from diagnosing medical conditions to composing poetry. Still, the original model continues to outperform machines in many ways. This is why, for example, we can ‘prove our humanity’ with trivial image tests online. What if instead of trying to make AI more brain-like, we went straight to the source?
Scientists across multiple disciplines are working to create revolutionary biocomputers where three-dimensional cultures of brain cells, called brain organoids, serve as biological hardware. They describe their roadmap for realizing this vision in the journal Frontiers in Science.
MANUFACTURA’s eggshell project transforms organic waste into a sustainable building material made from 3D printed eggshells.
An RNA-Peptide World
“I don’t want to replace the RNA world theory,” Carell said. But “I think we need an extension” to make it more plausible. He thinks that rather than evolving their complexity separately, RNA and peptides did it together as a single molecule, complementing each other’s functions.
Located in Austrailia, the CSIRO Parkes Radio Telescope picked up the strange signal stemming from Proxima Centauri.

On 29 April 2019, the Parkes Radio Telescope in New South Wales, Australia, picked up an unusual signal while searching for signs of intelligent life elsewhere in the universe. The telescope was observing Proxima Centauri, the nearest star to the sun and host to a number of exoplanets that are potentially habitable.
Scientists from Denmark and China have estimated germline mutation rates across vertebrates by sequencing and comparing genetic samples from 151 mother, father, and offspring trios from 68 species of mammals, fishes, birds and reptiles. A bioinformatics pipeline was designed to read, analyze and compare the genome mutations that occur yearly and between generations in each species.
The research was published March 1, 2023, in the journal Nature.
Knowing the germline mutation rate could allow a greater understanding of evolutionary drivers and be used to estimate when a species first arose. Despite the variety of evolutionary paths seen in 68 different species, researchers found the germline mutation rate to be relatively conserved.
For years, scientists have known there was something hidden above the entrance to the Great Pyramid. Now, they’ve finally revealed it.
