Why 21 cm is the magic length for the Universe
Posted by Shubham Ghosh Roy in categories: quantum physics, space
Photons come in every wavelength you can imagine. But one particular quantum transition makes light at precisely 21 cm, and it’s magical.

“Dynamic Soaring” Could See Interstellar Probes Reach Super Speeds
Posted by Jose Ruben Rodriguez Fuentes in categories: chemistry, energy, space
Covering interstellar distances in a human lifetime is far from easy. Going at 1 percent of the speed of light, it would take over 400 years to reach the closest star, and we have not been able to propel any spacecraft even close to that speed. But a new method aims to get to those speeds and maybe more – and it takes inspiration from the mighty albatross.
Chemical propulsion can be very useful in achieving high speeds pretty quickly, but there’s the drawback in that you need to carry the fuel with you, which means you need to be able to generate more thrust to shift the extra fuel and so on. It’s a huge issue when it comes to rocket science. A realistic alternative is ion propulsion, used to slowly and successfully maneuver the Dawn spacecraft, but it would take an equally long time to reach enough speed with such a steady but small acceleration.
Solar sails hold a more intriguing possible approach. Proposals such as the Breakthrough Starshot see lasers used to massively accelerate a spacecraft the size of a credit card to one-fifth the speed of light. But, you need to build a very powerful laser. A similar method using sunlight might also work, although not up to such a high speed.

The CRISPR Apostle: Rodolphe Barrangou
Posted by Jose Ruben Rodriguez Fuentes in categories: bioengineering, biotech/medical, drones, food, genetics, health
For millennia, humans have been harnessing #microbes to produce everything from breads, to cheeses, to alcohol. Now these tiny organisms have produced another powerful revolution — the gene editing tool CRISPR. Rodolphe Barrangou, Ph.D., was working at the food company Danisco, where he was trying to produce yogurt lines resistant to contamination. In a series of groundbreaking experiments, he helped uncover what CRISPR was, how it worked, and why it could be so transformative.

Long considered loners, many marsupials may have complex social lives
Posted by Dan Breeden in category: evolution
Mammals run the gamut of social organization systems, ranging from loose, ephemeral interactions like aggregations of jaguars in the South American wetlands to the antlike subterranean societies of naked mole-rats (SN: 10/13/21; SN: 10/20/20).
But marsupials — a subgroup of mammals that give birth to relatively underdeveloped young reared in pouches — have traditionally been considered largely solitary. Some kangaroo species were known to form transient or permanent groups of dozens of individuals. But among marsupials, long-term bonds between males and females were thought rare and there were no known examples of group members cooperating to raise young. Previous work on patterns of mammalian social evolution regarded about 90 percent of examined marsupial species to be solitary.
“If you look at other [studies] about some specific species, you will see [the researchers] tend to assume that the marsupials are solitary,” says Jingyu Qiu, a behavioral ecologist at CNRS in Strasbourg, France.

Building A Virtual Machine inside ChatGPT
Posted by Dan Breeden in category: robotics/AI
Unless you have been living under a rock, you have heard of this new ChatGPT assistant made by OpenAI. You might be aware of its capabilities for solving IQ tests, tackling leetcode problems or to helping people write LateX. It is an amazing resource for people to retrieve all kinds of information and solve tedious tasks, like copy-writing!
Today, Frederic Besse told me that he managed to do something different. Did you know, that you can run a whole virtual machine inside of ChatGPT?
Great, so with this clever prompt, we find ourselves inside the root directory of a Linux machine. I wonder what kind of things we can find here. Let’s check the contents of our home directory.

Fossilized Teeth of Giant Hominid Led Scientists to Speculate That Humans May Have Had Giant Ancestors
Posted by Dan Breeden in category: futurism
Gigantopithecus was a massive gorilla-like creature that stood 10 feet tall and weighed upwards of 1,100 pounds making it the largest primate that ever lived. It thrived in the tropical forests of Southern China during the Pleistocene Epoch between 2.6 million to 11,700 years ago.
Fossilized teeth from Gigantopithecus were first discovered by a Dutch paleontologist named GHR Koenigswald. Referred to as “dragon’s teeth,” these specimens were sold in Chinese apothecaries for their purported medicinal benefits.
According to reports, the size of the teeth led some early scientists to suggest they belonged to human ancestors who may have been giants: “The teeth, though large, have a few similarities to human teeth, and this led some paleomorphologists to speculate that humans might have had “giant” ancestors. Later discoveries of complete mandibles demonstrated that they were from extinct apes.”
