The iconic “retina scan” scene in Star Trek II: Wrath of Khan was not Shatner’s own eye.
It was an “eye double” software engineer.
(As the man himself says, your iPhone can take a more detailed picture these days, but it was high tech for 1982…)

“The laser, a 10-meter wide array on Earth, would heat hydrogen plasma in a chamber behind the spacecraft, producing thrust from hydrogen gas and sending it to Mars in only 45 days. There, it would aerobrake in Mars’ atmosphere, shuttling supplies to human colonists or, someday perhaps, even humans themselves.”

The only problem is that there’s no way to slow the thing down right now…”aerobraking” using current technology would cause gees of 8 or above for several minutes and temperatures hot enough to cook whatever’s in the ship to a nice toasty crisp.
But what if robots could design a receiving station with lasers to “catch” the ship and slow it down…?
Hmmm. Sounds like a science fiction work in progress…

Well, the writing was already on the virtual wall from the beginning. The anime had only one season.
White fanboys got butthurt by the use of diverse actors – anime is anime, but live action is real actors in the real world where “race” and ethnicity are still issues and women don’t actually look like hourglasses.
Ratings plummeted after the initial hype. Netflix always panders to the masses, so this is not surprising.
Adios, amigos. See you, space cowboy.

Technically, the two asteroids the DART is aiming at are a “binary” (they orbit each other).
The BBC’s explanation is pretty good.
They don’t even mention Bruce Willis until the final sentence.

Hang on, I think I’ve seen this before…
Oh.
Not such a great idea, then, to send them on an interstellar cruise…

The blood, sweat, and tears of pioneering astronauts could literally turn Mars regolith into building materials.
First, however, they’d need to get the 3D printers there…

It’s becoming increasingly common to see social media posts claiming that the mRNA COVID-19 vaccines, which include those made by Pfizer and Moderna, could alter a person’s DNA. Some posts even suggest that nano-machines are being injected into the body.

Yeah, I’ve seen some of these posts. Talked to a neighbor who was convinced Bill Gates was trying to inject us all with a chip to control our minds.
Is there any truth to these rumours? Could an mRNA vaccine be modifying your DNA?
No.
(Read the linked Cosmos article for more details!)
Actually, all you need to do is use logic and reasoning, apply some critical thinking, and demand lots of science-based evidence.
It’s called the Baloney Detection Kit and was introduced in a Cornell University undergraduate course about critical thinking and the scientific method by astrophysicist Carl Sagan.
In his book The Demon-haunted World, he lays out nine steps to bust BS and call out unscientific baloney. I use it with my second year undergrad students in a current news and global issues course.
The link above to the kit also outlines some of the most important logical fallacies to avoid, with number 8 and 9 being the most difficult to explain and convince people about (because they involve education about basic statistics).
So will this convince anti-vaxxers who make outlandish claims online?
Probably not. Unless it goes viral 😉.

The 128 baby bobtail squid will be used as part of research into the effects of spaceflight on beneficial interactions between microbes and animals.
https://www.bbc.com/news/science-environment-57339989
So why use squid instead of dogs, chimps, or other mammals?
The squid have an immune system which is similar to that of humans.
Ah.
And their distinct lack of a spine makes them similar to most politicians, too. Very helpful for finding out what might happen if we decide to…
Nah.

As the training progressed, the participants changed the way they used the device, which resulted in new finger coordination patterns. This was recorded in their hand movements as well as in their brains.

The only problem with the design is that you have to control it with your foot. Not ideal if you’re walking!
Not to worry. That’s the next step. Er, stage.

Using blobs of skin cells from frog embryos, scientists have grown creatures unlike anything else on Earth, a new study reports. These microscopic “living machines” can swim, sweep up debris and heal themselves after a gash.
