Native American tribe gets its land back after being displaced nearly 400 years ago

Posted by in category: futurism

Will they able to make good use of this land?đŸ€”đŸ€”.


The Rappahannock Tribe, a Native Tribe in Virginia, has reacquired 465 acres of sacred land at Fones Cliff.

Secretary of the Interior Deb Haaland and US Fish and Wildlife Service Director Martha Williams celebrated the tribe’s reacquisiton of the land Friday, according to a press release from the Department of the Interior.

In the new field of quantum computing, magnetic interactions could play a role in relaying quantum information.

In new research, Argonne scientists achieved efficient quantum coupling between two distant magnetic devices, which which may be useful for creating new quantum information technology devices — https://bit.ly/3uk88Q3

These stingless bees make medicinal honey. Some call it a ‘miracle liquid.’

Posted by in categories: biotech/medical, education

They come in many colors: golden, solid onyx, or striped dandelion and cinnamon. Their eyes can be beady black, slate gray, or even bluish-green. Their bodies may be as small as lentils or big as wine grapes. But the most amazing thing about stingless bees are the honeys they produce, which are increasingly being sought after for food and medicine.

In the Peruvian Amazon, people are just beginning to raise a few of the area’s 175 different species of stingless bees, which promise to help beekeepers and their communities. Historically, such honey has typically been harvested from the wild, which destroys the hives.

But in the last few years, scientists including Cesar Delgado, with the Instituto de Investigaciones de la AmazonĂ­a Peruana (IIAP), are teaching people to raise and keep the insects in sustainable ways.

Hubble smashes record for most distant star ever seen

Posted by in category: cosmology

The Hubble Space Telescope has smashed a record, identifying its most distant star ever. The star is so far away that its light has taken nearly 13 billion years to reach us, meaning it is from the first one billion years after the Big Bang.

Hubble’s previous record for farthest star observed, set in 2018, was for a star from 4 billion years after the Big Bang. So this new finding is a considerable step older and was only observable thanks to a fortuitous cosmic alignment. “We almost didn’t believe it at first, it was so much farther than the previous most distant, highest redshift star,” said astronomer Brian Welch of the Johns Hopkins University in Baltimore, lead author of the paper, in a statement.

The star in question, named Earendel, which means “morning star” in Old English, is massive, coming in at at least 50 times the mass of our sun. It is also millions of times brighter. However, even allowing for its mass and brightness, it is so far away that it was only possible to observe it thanks to a huge galaxy cluster that passed between it and us. The cluster’s gravity is so large that it warps the light coming from the star and acts as a magnifying class.

When the Magellanic Cloud galaxies get close, star formation peaks

Posted by in category: space

Like two great songwriters working side by side and inspiring each other to create their best work, the Magellanic Clouds spawn new stars every time the two galaxies meet.

Visible to the naked eye but best seen from the Southern Hemisphere, the Large and Small Magellanic Clouds are by far the most luminous of the many galaxies orbiting the Milky Way. New observations reveal that on multiple occasions the two bright galaxies have minted a rash of stars simultaneously, researchers report March 25 in Monthly Notices of the Royal Astronomical Society: Letters.

Astronomer Pol Massana at the University of Surrey in England and his colleagues examined the Small Magellanic Cloud. Five peaks in the galaxy’s star formation rate — at 3 billion, 2 billion, 1.1 billion and 450 million years ago and at present — match similarly timed peaks in the Large Magellanic Cloud. That’s a sign that one galaxy triggers star formation in the other whenever the two dance close together.

Retrotechtacular: The Transatlantic Radiotelephone System Of The 1930s

Posted by in categories: business, energy, internet

With the web of undersea cables lacing the continents together now, it’s hard to imagine that it wasn’t until 1956 that the first transatlantic telephone cable was laid. Sure, there were telegraph cables under the Atlantic starting as early as the late 1800s, but getting your voice across the ocean on copper was a long time coming. So what was the discerning 1930s gentleman of business to do when only a voice call would do? He’d have used a radiotelephone, probably at an outrageous expense, which as this video on the receiving end of the New York to London radio connection shows, was probably entirely justified.

The video details the shortwave radiotelephone system that linked New York and London in the 1930s. It starts with a brief but thorough explanation of ionospheric refraction, and how that atmospheric phenomenon makes it possible to communicate over vast distances. It also offers a great explanation on the problems inherent with radio connections, like multipath interference and the dependency on the solar cycle for usable skip. To overcome these issues, the Cooling Radio Station was built, and its construction is the main thrust of the video.

Using steampunk to explain quantum physics

Posted by in categories: computing, environmental, quantum physics

What do quantum computers have to do with smog-filled London streets, flying submarines, waistcoats, petticoats, Sherlock Holmesian mysteries, and brass goggles?

A whole lot, according to Nicole Yunger Halpern. Last week, the joined Jacob Barandes, co-director of graduate studies for physics, to discuss her new book, “Quantum Steampunk: The Physics of Yesterday’s Tomorrow.” In it, Yunger Halpern dissects a new branch of science—quantum thermodynamics, or quantum steampunk as she calls it—by fusing steampunk fiction with nonfiction and Victorian-era thermodynamics (the heat and energy that gets pumping) with . Yunger Halpern presents a whimsical lens through which readers can watch a “scientific revolution that’s happening in real time,” Barandes said, exploring mysteries even Holmes couldn’t hope to solve, such as why time flows in only one direction.

“This fusion of old and new creates a wonderful sense of nostalgia and adventure, romance and exploration,” Yunger Halpern said during a virtual Harvard Science Book Talk presented by the University’s Division of Science, Cabot Science Library, and Harvard Book Store. In steampunk, she continued, “fans dress up in costumes full of top hats and goggles and gears and gather at conventions. What they dream, I have the immense privilege of having the opportunity to live.”

Chemical-to-mechanical molecular computation using DNA-based motors with onboard logic

Posted by in categories: biotech/medical, chemistry

Current DNA computation techniques are slow in generating chemical outputs in response to chemical inputs and rely heavily on fluorescence readouts. Here, the authors introduce a new paradigm for DNA computation where the chemical input is processed and transduced into a mechanical output in the form of macroscopic locomotion using dynamic DNA-based motors.

Relativity’s time dilation may limit the quantum world

Posted by in category: quantum physics

A new theoretical paper has tackled the phenomenon of quantum decoherence.


A new theoretical paper has tackled the phenomenon of quantum decoherence, the process by which objects slip out of the quantum world and start behaving classically. The paper approaches this in a new way by applying an effect of general relativity to decoherence. The paper claims that gravity is the key to the disparity between the weird quantum world and the everyday, familiar world of human-sized objects in which we live.

Schrödinger’s cat is an example of a quantum system which might decohere due to time dilation — and myriad other interactions.
