Did you see this? It's an artist's conception of how gravity from the tiny moon Daphnis creates ripples in Saturn's rings - created by Kevin Gill of NASA.

This image was pretty popular here, and elsewhere on the web - but people often don't come out and say from the start that it's not a photo. The actual photos are less beautiful but... hey, they're real! And the ripples look different in the photos. Let's take a look.

Saturn's moon Daphnis in the Keeler gap in the A ring, as artistically depicted by Kevin Gill of NASA here: https://www.flickr.com/photos/kevinmgill/29111229131 The moon, sitting in the gap, creates lots of ripples in the inner part of the ring and a few in the outer part. Saturn can be seen below.

This 2005 photo, taken by the Cassini probe, was the first time anyone actually saw Saturn's moon Daphnis! It's only 8 kilometers across.

This gap in Saturn's A ring was first discovered by Voyager, and it was named the Keeler Gap. It's 35 kilometers wide. I guess this gap let people guess the existence of a moon, and later the ripples in the A ring let people guess where the moon must be! I don't really know the history here.

Daphnis is visible as a white speck between a more rippled ring to the left and a less rippled one to the right. From https://photojournal.jpl.nasa.gov/catalog/PIA06237 "Cassini's confirmation that a small moon orbits within the Keeler gap in Saturn's rings is made all the more exciting by this image, in which the disk of the 7 kilometer-wide body (4-miles) is resolved for the first time. The new body, provisionally named S/2005 S1, was first seen in a time-lapse sequence of images taken on May 1, 2005, as Cassini began its climb to higher elevations in orbit around Saturn (see PIA06238 for the movie). This view was acquired one day after the discovery sequence of images and has allowed scientists to measure the moon's size and brightness. This image was obtained with the Cassini spacecraft narrow-angle camera on May 2, 2005, at a distance of about 594,000 kilometers (369,000 miles) from Saturn. Cassini was about 525,000 kilometers (326,000 miles) above the ringplane when the image was taken. Resolution in the original image was 3 kilometers (2 miles) per pixel. The image has been magnified by a factor of two, and contrast has been enhanced, to aid visibility of the small moonlet."

In de zoektocht naar het terugdringen van de (winter)sterfte onder honingbijen waagt het Belgische biotechbedrijf Apix Biosciences zijn kans met een stuifmeelvervanger.

Maar deze nieuwe technofix doet niets aan de kern van het probleem: “Bijen hebben nood aan meer onbespoten bloemen”.

I have two burning questions about the VIewPoint AI screen reader: 1. Why for WIndows only, and 2. Where does the collected data go? I did not see any disclaimers on their website. What did I miss?
On the flip side, so cool to see AI being put to a good use. Developers, please do not relax though, you still have to take care of accessibility. :) dragonscave.space/@Woody/11447…

Random reminder that #BillGates is the reason why AstraZeneca #COVID vaccine is patent-encumbered:
wired.com/story/opinion-the-wo…

> Gates bragged about convincing Oxford University not to open-license its vaccine. Gates leveraged his $750 million donation to the university for vaccine research—even though its vaccine was developed in a publicly funded lab. Eventually, Oxford sold the sole right of production to AstraZeneca, with no guarantee of low prices and an extraordinary opportunity for profit.

For my disabled followers, what do you consider when thinking about inclusive swag? Swag in this case meaning t-shirts, coffee mugs, backpacks, stickers, etc. that you acquire through conferences, work, or other places.
I struggle to name what I look for in swag for it to be inclusive as a blind person; I think the most I'd look for is cool tactile design on t-shirts and perhaps embossed designs on stickers. But even that's a stretch; I've never felt strongly enough to remotely consider this, and that's why I'm here! I also consider things like Braille to be a novelty, and don't feel excluded when it doesn't exist. In a nutshell--I don't really care. But I'm sure someone out there does. Surely there's at least one of you.
Please boost for reach.

@Bruce I have read that some influential #Catholic individuals who supposedly belong to a group called Opus Dei were in and around the Vatican before the conclave began trying to somehow influence the deliberations. I don’t have any skin in the game, as I have said before elsewhere I’m not #Catholic even though I was blessed with Jesuit education through high school and college. I think there will be continuing pressure, probably on all sides, to politicize the papacy, and to the extent it can be resisted I hope it is.
