NASA said it hoped to create a “robust, American-led commercial economy in low-Earth orbit”.
NASA says the ISS will operate until 2030 before the agency hands over to commercial companies.
The strongest magnetic field ever measured anywhere in the universe has failed to produce detectable magnetic monopoles. These hypothetical particles are predicted by many calculations of possible phenomena beyond the standard model of particle physics, but more than a century of searching still hasn’t turned up any signs of them.
All magnets that we know of have at least two poles – typically a north and south pole – with opposite magnetic charges. However, some models of the universe predict that there should be particles with only a north or a south pole called magnetic monopoles. For example, the existence of magnetic monopoles would explain why electric charge is quantised, meaning it comes in packets with a minimum size.
Over the past century or so, researchers have searched for magnetic monopoles both in space and in the smash-ups of particles at colliders, but they haven’t been found yet. Igor Ostrovskiy at the University of Alabama and his colleagues looked for monopoles being produced by a proposed phenomenon called the Schwinger effect, wherein extremely powerful magnetic fields could spontaneously produce magnetic particles and their antiparticles.
You can’t really enter into “another dimension” as science fiction would have you believe. Instead, dimensions are how we experience the world. But some aspects actually suggest to one expert, not one but two dimensions of time. If it were true, the theory could actually heal the most glaring rift in physics —between quantum mechanics and general relativity.
Weighing in at seven times the mass of our sun, the dark object is by far the best-yet candidate for a free-floating stellar-mass black hole.
Hold on to your hats. SpaceX Starlink Premium offers much faster internet to those that need it most, like businesses and other organizations. It’s the latest in Elon Musk’s plans for the service.
Antiretroviral therapy, the standard treatment for HIV, can remove any trace of the virus from the blood, but a hidden reservoir of HIV persists in patients who are in treatment. That means patients are never truly cured and need to be on HIV drugs for the rest of their lives.
Researchers have yet to discover a way to eliminate the virus in its latent stage, but new, early-stage research suggests a landmark cancer drug — pembrolizumab, also known as Keytruda — may be able to help. In a study published Wednesday in Science Translational Medicine, researchers looked at 32 patients that had both cancer and HIV and found that pembrolizumab, which revives the immune system and encourages it to attack tumors, also has the ability to flush HIV out of its hiding spot in immune cells.

If the Ingenuity helicopter would fly at night on Mars, its very possible the whirring rotors would create enough static electricity in the extremely dry Martian atmosphere to cause the air around the craft to glow.
“The faint glow would be most visible during evening hours when the background sky is darker,” said William Farrell, from Goddard Space Flight Center and lead author of a paper on this topic. “NASA’s experimental Ingenuity helicopter does not fly during this time, but future drones could be cleared for evening flight and look for this glow.”
If you’ve ever shuffled your feet across a wool carpet on a dry winter day, and then reached out to touch a metal doorknob, you’re familiar with the static discharge that creates a little zap — a spark — that leaps between your fingers and the metal knob.
Summary: A breakdown in regulatory mechanisms causes iron to build up in the brain during aging, increasing oxidative stress and increasing the risk of age-related cognitive decline, a new study reports.

Breakdowns in regulatory mechanisms cause iron to build up in the brain as organisms grow older, increasing oxidative stress and causing cellular damage, according to a Northwestern Medicine study published in the journal eLife.
The carmaker’s confidence this early in the year surprised analysts skeptical it can boost global annual production volumes by 25% at least.
Sorry to our fellow hopeful space nerds, but we have to burst everyone’s warp bubble. Despite recent reports that scientists have “accidentally created a warp bubble,” it looks like warp speed is still a few baby steps away. But all hope is not lost: a group of scientists led by Dr. Harold G. “Sunny” White has proposed a structure that could actually be built in the real world and used to study the Casimir effect. It might be a baby step, but it’s a real one.
Breaking the ‘cosmic speed limit’ with the Casimir effect
To make a warp drive, first you need to master the Casimir effect. The Casimir effect, for the uninitiated, is a very small attractive force that exists between two uncharged but conductive parallel plates that are held very, very close together. It used to be a purely hypothetical offshoot of relativity. However, now that we’ve seen it happen in real life, it’s high on the list of real-world phenomena scientists are investigating to figure out how we might finally crack the problem of interstellar space exploration.
