For the program, the 9- to 12-year-old students designed an experiment in which epinephrine samples were placed into tiny cubes and sent to the edge of space via either a high-altitude balloon or a rocket. Once back on Earth, researchers from the John L. Holmes Mass Spectrometry Facility at the University of Ottawa tested the samples and found that only 87% contained pure epinephrine, while the other 13% had been “transformed into extremely poisonous benzoic acid derivatives,” according to a University of Ottawa statement(opens in new tab).
So…uh…why would an astronaut have this thing in space to begin with? NASA should know the full medical history of all its astronauts before even considering sending them into space.
“I’m less frightened by a Sydney that’s playing into my desire to cosplay a sci-fi story than a Bing that has access to reams of my personal data and is coolly trying to manipulate me on behalf of whichever advertiser has paid the parent company the most money.
“Nor is it just advertising worth worrying about. What about when these systems are deployed on behalf of the scams that have always populated the internet? How about on behalf of political campaigns? Foreign governments? “I think we wind up very fast in a world where we just don’t know what to trust anymore,” Gary Marcus, the A.I. researcher and critic, told me. “I think that’s already been a problem for society over the last, let’s say, decade. And I think it’s just going to get worse and worse.”
It is this subsurface ocean, or rather its interaction with the ice shell that covers it, that a team of researchers led by the Catholic University of Louvain (UCLouvain) in Belgium hope to better understand. More specifically, they wish to understand how the ocean’s depth and the pressure exerted by the icy shell on the underground water body influence the formation of tidal motions and currents inside of it.
When I first heard of “Attack on Titan,” I was disappointed to learn that it didn’t take place actually on Titan. (The title in English is a mistranslation. It should be “Attack of the Titans” or “The Titans Attack” or even “Attacking Titans,” depending.) In any case, it’s a disgusting manga/anime with nothing to do with the icy moon of Saturn. Except for the name. And even that’s a misuse (they should have used “giant” as the storyline is very loosely based on Ymir and the frost giants of Scandinavian myth).
An asteroid is on its way to Earth, but don’t worry – the end is here Not here. The asteroid, named 2023 BU, is about the size of a van and is expected to miss our planet during Thursday’s flyby. However, according to a NASA scientist, it will be “one of the closest approaches of a known near-Earth object ever recorded.”
Since the Hayabusa2 returned with the sample from the Ryugu asteroid in December 2020, several important discoveries have been made – most notably analyzes confirming the presence of substances thought to be the building blocks of life on the asteroid, such as liquid water and organics fabrics.
Hayabusa-2 took several years to land on Ryugu (literally “Dragon Palace”), pound out just over 5 grams of asteroid material, and bring it back to Earth (landing in Australia in late 2020).
NASA scientists have confirmed not just frozen water but liquid — inside crystals called pyrrhotites. JAXA scientists (pictured above with Prof Tsuchiyama of Ritsumeikan University, my main employer!) continue to check the density of the samples.
The water is similar to the carbon dioxide-laden water of hot springs. The research teams have already discovered over 20 amino acids, the basic protein building blocks of carbon-based life.
Another theory called “panspermia” proposes that a key mineral (boron) missing on early Earth came in an asteroid from Mars. ☄️ Hmm. Did Mars produce asteroids? Or more like asteroids hit Mars and broke off lots of tiny fragments? That somehow survived the journey to Earth?
Seems a little unlikely. But there is now evidence that at least some proteins came from space rocks.
So, sorry, Ridley. This isn’t how it happened. Cool movie, though.
A new study that analyzes data from more than 50,000 amateur stargazers finds that artificial lighting is making the night sky about 10% brighter each year.
Each spring in my Current Events and Global Issues class, I have students read about environmental issues.
Pollution is obviously related. But they almost never guess the “seven types of pollution” (yes, I know some people country eight, or ten, or even twelve…it all depends on how you categorize them).
Maybe it’s because most of my students (to the order of 90%) come from medium and large cities. To me, having grown up in a mostly rural area (in elementary school, my town had about 400 residents and in junior and senior high I lived in a “queen village” that had — gasp — an incredible 4,000 residents) — well, being surrounded by darkness was no big deal.
We could see stars from our backyard. Lots of stars. We learned all the major constellations (of the Northern Hemisphere, anyway, since that’s what we could see).
And more importantly we could see lightning bugs (or “fireflies” or “glowworms” or “candle bugs” etc). Decreasing water quality is thought to contribute to their declining numbers, but it’s far more likely that our insistence on lighting up the skies all the time are preventing them from finding a mate (hence the reason they “flicker” at night).
I’ve been testing ChatGPT over the last couple of days. (If you don’t know what this chatbot is, here’s a good NYT article about ChatGPT and others currently in development.)
The avowed purpose of ChatGPT is to create an AI that can create believable dialogues. It does this by scouring the web for data it uses to respond to simple prompts.
By “simple,” I mean sometimes “horribly complicated,” of course. And sometimes a little ridiculous.
Somehow, I doubt that people in the US said “livin’ the dream” in the ’50s…
As has been pointed out, chatbots only generate texts based on what they have been fed, i.e., “garbage in / garbage out.” So if you push the programs hard enough, they will generate racist, sexist, homophobic etc awful stuff — because unfortunately that kind of sick and twisted garbage is still out there, somewhere online in a troll’s paradise.
So far, I have asked the program to:
Write a haiku about winter without using the word “winter”
Write a limerick about an Irish baseball player
Write a dialogue between God and Nietzsche (I just had to…)
Imagine what Jean-Paul Sartre and Immanuel Kant would say to each other (see above) but using US ’50 slang
Have Thomas Aquinas and John Locke argue about the existence of God (that one was fun)
Write a 300 word cause-effect essay about climate change
Write a 300 word compare and contrast essay about the US and Japan
Write a 1000 word short science fiction story based on Mars
Write a 1500 word short science fiction about robots in the style of Philip K Dick
I love the “illustrative diagram” note for people who might complain this is not scientifically accurate due to scale.
…if you are lucky enough to live Western Europe, parts of northwestern Africa, and some of the Americans…
As for why the Moon appears red…
“You’ll actually be seeing every sunrise and every sunset occurring around the Earth at once. All of that light will be projected on to the Moon.” (Dr Gregory Brown, Royal Observatory
And if you happened to be standing on the Moon at the time, you’d see a blood ring encircling the Earth in front of you (ah, assuming you were not on the other side of the Moon).
Come on. Somebody has got to figure out how to get a picture of that.
I’ve never really experienced the so-called “writer’s block.” Not that I’m bragging…but I often just don’t find I have enough time to write.
By which I mean, writing seriously. It’s easy, however, to find time here and there just to jot down some random thoughts.
(Aside note: if you type really quickly on the WordPress smartphone app, it autocorrect “random” to “radon,” which would put you in an entirely different frame of mind.)
I started writing stories when I was in 5th grade. Our teacher gave us a list of vocabulary each week — about 10 to 12 words, I think — and said we had two choices: 1) write down all their definitions along with a sample sentence, or 2) work them into a short story to show that we understood the meaning of the words.
I chose the 2nd option. In fact, I was the only one who did out of a class of about 25.
The thing is, the teacher wanted us to read them at the front of the room.
Man, that was not something I was looking forward to. But somehow I managed.
I wrote nothing but detective stories, all in the first person. At some point, I borrowed my mother’s old manual typewriter (originally my grandfather’s, from the 1950s) and typed them all out. I still have most of them.
But my peak as an elementary school age creative writer came part-way 6th grade, when I attempted to write my first horror story.
