The latest Starlink satellites launched on Jan. 24 are equipped with laser links, and all Starlink satellites launched next year will be equipped with laser inter-satellite links, Elon Musk, SpaceX chief engineer confirmed on Twitter.

“All sats launched next year will have laser links. Only our polar sats have lasers this year and are v [version] 0.9,” Musk tweeted on Monday.

A Twitter user noticed a difference in a photo of the stack of 10 Starlink satellites deployed on Sunday’s Transporter-1 rideshare mission, and asked Musk if an object that looked like a black pipe was lasers, which he confirmed.

Laser beams can be used to change the properties of materials in an extremely precise way. This principle is already widely used in technologies such as rewritable DVDs. However, the underlying processes generally take place at such unimaginably fast speeds and at such a small scale that they have so far eluded direct observation. Researchers at the University of Göttingen and the Max Planck Institute (MPI) for Biophysical Chemistry in Göttingen have now managed to film, for the first time, the laser transformation of a crystal structure with nanometre resolution and in slow motion in an electron microscope. The results have been published in the journal Science.

The team, which includes Thomas Danz and Professor Claus Ropers, took advantage of an unusual property of a material made up of atomically thin layers of sulfur and tantalum atoms. At room temperature, its crystal structure is distorted into tiny wavelike structures—a “charge-density wave” is formed. At higher temperatures, a phase transition occurs in which the original microscopic waves suddenly disappear. The electrical conductivity also changes drastically, an interesting effect for nano-electronics.

In their experiments, the researchers induced this phase transition with short laser pulses and recorded a film of the charge-density wave reaction. “What we observe is the rapid formation and growth of tiny regions where the material was switched to the next phase,” explains first author Thomas Danz from Göttingen University. “The ultrafast transmission electron microscope developed in Göttingen offers the highest time resolution for such imaging in the world today.” The special feature of the experiment lies in a newly developed imaging technique, which is particularly sensitive to the specific changes observed in this phase transition. The Göttingen physicists use it to take images that are composed exclusively of electrons that have been scattered by the crystal’s waviness.

Puts into perspective the cycles and forces that have driven the successes and failures of all the world’s major countries throughout history. Dalio reveals the timeless and universal dynamics that were behind these shifts, while also offering practical principles for policymakers, business leaders, investors, and others operating in this environment.

From the #1 New York Times bestselling author of Principles and legendary investor Ray Dalio, who has spent half a century studying global markets, The Changing World Order examines history’s most turbulent economic and political periods to reveal why the times ahead will likely be radically different from those we’ve experienced in our lifetimes.

If our universe is a bubble that inflated inside a larger multiverse, it might bear scars from collisions with nearby bubbles.

What lies beyond all we can see? The question may seem unanswerable. Nevertheless, some cosmologists have a response: Our universe is a swelling bubble. Outside it, more bubble universes exist, all immersed in an eternally expanding and energized sea — the multiverse.

The idea is polarizing. Some physicists embrace the multiverse to explain why our bubble looks so special (only certain bubbles can host life), while others reject the theory for making no testable predictions (since it predicts all conceivable universes). But some researchers expect that they just haven’t been clever enough to work out the precise consequences of the theory yet.

Forever we have held a view that AGING, DISEASE & DEATH is an un-alterable eventuality, those who dared question were ostracised for playing God.

If you choose to look deeper you will surely be amazed. Bowhead whales live for over 200 yrs “Turriptosis Dohnri” is a Jellyfish that lives forever. Can these #genetics traits be replicated in humans? Could the removal of #senescence #cells that accelerates aging be the answer Is it even possible to control or reverse aging? Can we grow old healthily? 150000 die every day & over 100000 of them are caused by aging.

This tech could be more practical than tokamaks.

Two competing nuclear fusion companies, each with venture capital superstars as major investors, say we’re approaching the “Kitty Hawk moment” for their technology as early as 2025.

JetPlay has launched Ludo, a game creation platform that uses artificial intelligence to accelerate the creative process.

The Seattle-based JetPlay has launched the open beta of Ludo, following a successful closed beta with participation from independent studios around the world. It will be a big test about whether automation can be useful in the domain of creativity, where humans have dominated so far.

Ludo is a game ideation platform that helps teams come up with ideas for games as well as images that can help them generate concept art. To me, this could go either way depending on the quality of the results. If it doesn’t work well, it could be a terrible idea, spitting out clones of popular games or otherwise leading creators astray. If it works well, however, it could accelerate creative moments and put your imagination on turbocharge, giving you a place to start your creative work.
