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.
An intense X2.3-class flare was released by the sun yesterday, followed by several M-class flares, which caused a series of radio blackouts around the world.
A wildfire destroyed 90% of a town in California. Now, it’s using building ordinances to entice insurance companies back. Could Washington soon follow the strategy?
The data from the reboost, scheduled for Nov. 8, will help inform design for a larger Dragon to deorbit the ISS.
The Milky Way Has Already Started The Process Of Colliding With The Andromeda Galaxy, An Event Previously Predicted To Be Four Billion Years Away

“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.
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.
NASA’s Juno spacecraft has just completed its 66th flyby of Jupiter, and the latest batch of images it has sent back to Earth are truly spectacular.
The spacecraft was launched back in 2011, reaching Jupiter five years later in 2016 after journeying for 1.7 billion miles. Ever since then, the probe has been zipping past Jupiter and its moons, capturing images and sending back data bursting with exquisite details.
“Jupiter is the Rosetta Stone of our solar system. Juno is going there as our emissary—to interpret what Jupiter has to say,” Scott Bolton, Juno’s principal investigator, said in a statement on NASA’s website.
In an incredible feat that redefines biological boundaries, scientists have successfully engineered animal cells capable of photosynthesis.
This breakthrough, led by Professor Sachihiro Matsunaga at the University of Tokyo, could transform medical research and aid in advancing lab-grown meat production.
Photosynthesis, traditionally exclusive to plants, algae, and certain bacteria, is a process that uses sunlight, water, and carbon dioxide to produce oxygen and sugars – essentially “feeding” the organism.
There have been some laboratory experiments and theoretical work done to validate aspects of the plasma magnet propulsion concept. The Plasma Magnet is a wind drag device invented almost twenty years ago by Dr. John Slough from the University of Washington. A rocket that uses a propellant to create momentum. A plasma magnet (newer / Wind Rider design) uses the pressure of the solar wind to gather momentum. This type of propulsion actually exists in nature. A dandelion coasts upon the wind to its ultimate destination.
The plasma magnet drive with dynamic soaring is a system that could be plausibly scaled for human crewed missions up to 2–3% of light speed without needing gigawatt power systems. It seems one of the systems with the fewest technological challenges. There are many other proposals to get to this speed.
Between 1.8 billion and 800 million years ago, earthly life was in the doldrums. During this period, called the “boring billion,” the complexity of life remained minimal, dominated by single-celled organisms with only sporadic ventures into multicellular forms. This era set the stage for the later emergence of complex multicellular life, marking a key chapter in evolutionary history.
