Swedish Researchers Unveil Game-Changing Optical Communication Tech for Space

Posted by in categories: innovation, space

Swedish scientists report a new breakthrough in technology that could transform optical communication in deep space, according to recently published research.

In a study led by a team at Chalmers University of Technology in Sweden, researchers have developed a silent amplifier and ultra-sensitive receiver that can facilitate high-fidelity transmissions over vast distances, showing promise for long-distance space communication.

True humility is rare today. It takes courage and a strong stance. It’s the story of Grigori Perelman, who proved the Poincaré conjecture — the only one of the seven Millennium Prize Problems solved by humanity. 1️⃣ In 1990s, Perelman worked at UC Berkeley. Top universities tried to hire him. A hiring committee at Stanford asked him for a C.V. to include with requests for letters of recommendation. But Perelman said: “If they know my work, they don’t need my C.V. If they need my C.V., they don’t know my work.” he received several job offers. But he declined them all. 2️⃣ In 2002–2003, he posted three manuscripts on arXiv where he solved the Poincare problem. On a PREPRINT server. Not in a journal! He did not care about publishing them in Nature. He did not care about getting them peer reviewed. He just wanted to make his work publicly available. Several leading math groups immediately started checking his proof. 3️⃣ In 2006, he was awarded a Fields Medal for his work on the Ricci flow and Poincare conjecture. But Perelman declined it: “[The prize] was completely irrelevant for me. Everybody understood that if the proof is correct, then no other recognition is needed.” He did not attend the ceremony. He was the only person to have ever declined the prize. 4️⃣ In 2010, Perelman was awarded a Millennium Prize ($1,000,000). He did not attend a ceremony in Paris as well. He considered the decision of the Clay Institute unfair because he wanted to share the prize with Richard Hamilton (who had a big influence on Perelman in 1990s). “The main reason is my disagreement with the organized mathematical community. I don’t like their decisions, I consider them UNJUST.” ❗️Why I am writing all this? Because: There’s no fairness in academia. It’s unjust and often illogical. It’s full of competition and unkindness. Perelman was very sensitive to it. So, he left mathematics… IF we don’t want to lose brilliant minds like this… IF we want our kids to love science as they grow up… Then we should focus on making it a better place. Less pressure on tenure track professors. No pursuit of metrics. No emphasis on awards. More mentorship and quality research. We need it. #science #research #engineering #mathematics #scienceandtechnology

RNA-targeting CRISPR reveals that hundreds of noncoding RNAs are essential—not ‘junk’

Can someone smarter than I tell me if this has any implications regarding the Covid vaccine?


Genes contain instructions for making proteins, and a central dogma of biology is that this information flows from DNA to RNA to proteins. But only two percent of the human genome actually encodes proteins; the function of the remaining 98% remains largely unknown.

Holographic-inspired lenses could unlock ‘3rd dimension of imaging’ in future VR headsets and smart glasses

Posted by in category: futurism

Future VR headsets could use a new type of lens inspired by holographic devices. The bilayer bifocal lens relies on external voltage to change the intensities in the foci.

The Milky Way Has Already Started The Process Of Colliding With The Andromeda Galaxy, An Event Previously Predicted To Be Four Billion Years Away

Posted by in category: space

“The circumgalactic medium plays a huge role in that cycling of that gas. So, being able to understand what the CGM looks like around galaxies of different types — ones that are star-forming, those that are no longer star-forming, and those that are transitioning between the two — we can observe [how] changes in this reservoir may actually be driving the changes in the galaxy itself.”

As technology evolves astronomers will likely be able to look at the CGM of other more distant galaxies and learn more about them as well.

The colliding of galaxies sounds terrifying.

SpaceX Dragon’s Latest Delivery Ignites Cutting-Edge Research on the ISS

Posted by in category: space travel

New science experiments and research samples, delivered on Tuesday by the SpaceX Dragon cargo spacecraft, were installed on Wednesday on the International Space Station (ISS). Meanwhile, science activities and lab maintenance continue to support the smooth operation of the orbital outpost.

Crew Begins Unloading and Installation

The four NASA astronauts representing the Expedition 72 crew, including Flight Engineers Don Pettit, Nick Hague, and Butch Wilmore, as well as Commander Suni Williams, spent the day unloading Dragon’s research-packed cargo. Arriving on November 5, Dragon brought advanced research equipment and temperature-sensitive specimens, which the crew quickly transferred to the ISS, placing them in dedicated research racks and cold storage for upcoming experiments.
