Okay look I'm still not drawing any conclusions here but I'm definitely seeing a trend emerge.

One of the most amazing things about nature is that kelp isn't a plant

[infiniteglitterfall]

About 30 years ago, an American botanist dug into the mud of a dried-up lake in China and found 1,000-year-old lotus seeds. She studied them carefully and put them in a pot on her lab's windowsill. They sprouted a few weeks later. "That took no effort. I thought that if she could do it, so can we," says Dr. Sarah Sallon, a pediatrician at Hadassah Medical Center, where she founded the Natural Medicine Research Center 25 years ago. The lotus that flowered on that windowsill in the United States sent Sallon on a years-long journey of raising date palms based on 2,000-year-old seeds. She even ate the fruit and then carried on with her botanical detective thriller.

At the end of her quest she proposed a solution to intriguing historical questions: What are the biblical plants tsori and afarsimon? What links them? And where did they disappear to?

....The fact that the Commiphora that sprouted [from their 1,000-year-old seed] resembled varieties found in Madagascar, not far from Sheba, adds to the hope that maybe the small plant is the legendary afarsimon that vanished from history in the eighth century. But alas, the plant at Kibbutz Ketura produced no aroma.

"We waited several years hoping that as it grew it might become fragrant. And we also sent specimens to chemists at the University of Western Australia and the University of Strasbourg in France," Sallon says. "What they found were almost no compounds associated with fragrance but many very medicinal ones including those with anti-inflammatory compounds."

Sallon, therefore, has a few key questions about the afarsimon. How is it that a plant that thrived for 1,000 years on large farms at the Dead Sea vanished without a trace? How is it that no archaeological excavation in the region, from Qumran in the north to Masada in the south, has found any afarsimon seeds?

....Cautiously, Sallon proposed a hypothesis for all the mysteries. She believes that the plant she found is a Commiphora that grew naturally at the Dead Sea, and that it may be the healing tsori mentioned in the Bible and known since the time of the Patriarchs.... [and that] ancient farmers used it as the stock for the aromatic Commiphora – the legendary afarsimon. This grafting gave Judean farmers the ability to grow large afarsimon fields and become a perfume powerhouse. This solution solves all the mysteries: Grafted plants often don't bear seeds, so no afarsimon seeds have been found at archaeological digs.

This is so cool. I can't believe people are sprouting seeds from archaeological digs and bringing extinct species back to life to learn about!

And it's so appropriate that it's two of the oldest cultures in the world that are doing this. I can't wait to see what else people will sprout!

Hyloscirtus tolkieni

Also known as Tolkien Frog

A new species of frog has been described from the tropical Andes of Ecuador and was named after the well known fantasy author J.R.R. Tolkien.

The scientists who published the first description of the species (Juan C. Sánchez-Nivicela, José M. Falcón-Reibán, and Diego F. Cisneros-Heredia) said that they named the frog after Tolkien because “the amazing colours of the new species evoke the magnificent creatures that seem to only exist in fantasy worlds."

They also paraphrase The Hobbit in the introduction of their paper (see photo 4)

The adult frogs appear to be nocturnal animals

I like the bug facts, learning stuff is cool

HELL YEAH. I love science :D

[housecow]

i cannot give details bc. doxxing. but y’all i just had a defining moment for my research!!! the moment im back in TX i will feast in honor of it :3

[ices-casket]

Hanging out with my friend and her brother was drawing with chalk, so I thought why not and joined him. (He looks a little wonky 😵‍💫)

And the angle that my friend saw

Extra drawing under the cut

The angle makes his face look extra weird so I just cropped it but there was text

"You have to wear sunscreen."

I know I yap a lot, but OML, I saw an aerial performance and thought 'top gun au. Now.' I need to touch grass. I enjoyed the cosi installment tho (science <33 (Nilered/Blue NEEDS to post another video) (the helicopter flying overhead kept distracting me))

I LOVE THE GLOBE OF DEATH⁉️ LIKE MAV AND GOOSE AS RIDERS WITH CAROLE STANDING IN THE MIDDLE??? My friend got to go in it was so cool.

I shouldn't be posting this much, but I draw quite a bit (I might just draw a few things and put it all in one post idk)

Because I’m a science bitch with a degree in science bitch shit (it was math-physics), I’d like to just explain my issue with there being a perfect eclipse in all the Dragon Age: the Veilguard promo material. Which is that it doesn’t work.

Like an eclipse isn’t just a moon blocking out the sun, it’s a moon with the same relative size as a sun, perfectly aligning with the sun. Any old planet can have an eclipse, it’s very hard to have a perfect eclipse. Often times the moon and the sun do not have the time relative size, thus leading to them lining up, but it being a partial eclipse with what’s called an annulus or ‘ring of fire’. The eclipse we had back in April was a perfect eclipse, meaning that it did not have a ring of fire, and that you could look at it! Don’t look at a partial eclipse with an annulus, it may look like a total eclipse, but it’s not. You will get hurt.

Now the issue is that the Thedas moon can’t do that.

See these moons?

See this sun?

The moons shown are bigger, in fact far too big to do a total perfect eclipse. It would just be a total eclipse with the sun being blocked out. So, the Moon cannot be the solar eclipse moon. This is where the problems start.

So what about the second moon of Satina that’s never been depicted?

Well, first off, for the big moon to be that big, it must either be very very large, or very close (remember, relative size, large items look bigger, but so do close up items). Now if it’s a large moon, then Satina could be a moonmoon, it could be hiding, we could be looking at a binary moon system, or Satina and the Moon could be far apart not affect each other. In that final case though, it does mean you should have more eclipses, so I suspect it’s not that.

So that leaves us with the others. Now, in order:

I’m just guessing it’s not a moonmoon. I would love it to be a moonmoon. But I don’t think it is. Mostly because no one cares about moonmoons except me and other people who find the name hilarious. Also that would make Satina not a moon of Thedas, but a moon of the Moon.

The moon isn’t hiding. I love the idea of a hiding moon, but it means that thw two moons have to have the same orbital speed. Or, the mass/orbital radius (distance from planet to moon) ratio has to be the same for both. But that’s not possible. Let’s say the Moon mass is 1 and it’s radius is 1. Then the mass/radius ratio is 1. Okay, so we take the second moon and make it small, let’s say half the size of the Moon, then the radius has to be 0.5. And sight lines are more or less a linear relationship, so that would mean the relative size of both moons would be the same. Now while he’s, this could be the case, BioWare’s also made it clear Satina is the smaller moon. So this doesn’t work.

Binary moon system. Honestly this would be two giant moons orbiting each other and is just a large moonmoon then. No I will not be explaining the physics of this. But it’s functionally that small things don’t actually orbit large things, small and large things orbit around the center of mass of their system, which just so happens to generally be in the center of the larger object.

The final one honestly could work! Honestly this is the most probable. That the Moon is big and close, and that Satina is much further away. Now, there does become an issue of Satina needing to be fairly large to do that, and at that point Satina and the Moon would gravitationally affect each other. But there’s probably a gravitational sweet spot where that’s not the case. However I’m not doing the math.

So what if the moon is just super close? Well… it would still be pretty big actually. Considering it takes up so much of the sight line, even if it’s super close, that’s large as shit. Furthermore, it’s a sphere, and thus it must be Of A Certain Size. The smallest spherical object in our solar system is still ~400km in diameter. However most spherical moons do tend to be bigger than this. Our moon is around 3400km in diameter, though it is unusually large.

As a final note, I do suspect that it’s just the 4th one of these, combined with Satina having phases, as the Moon is always a full moon, yet art in Thedas depicts phases. Likely referencing Satina.

So, ultimately I’m still wondering why there is a perfect total eclipse in the trailer and art, why Thedas has and knows about these things. Also why the fuck doesn’t Thedas have more imperfect eclipses with their giant moon! That should be blocking out the sun semi regularly! It’s not even that hard! It’s giant, and earth has yearly eclipses, Thedas should be having so fucking many okay?

my theory of science as a field is that. you know those light box things we would use to trace pictures as kids? my theory is that the true nature of reality is this wild complex crazy complicated picture, and it’s covered by about 100 layers of paper and that’s what we can perceive. and science is us putting that on a light box and trying to trace it. and every time someone makes a new discovery it’s like peeling away one tiny layer of paper to make it easier for the next person to trace.

Something that really stuck with me my first year of med school was learning that women are born with all of their eggs. They won't produce any more over the course of their life, and they grew with us whilst in the womb. That just tells me that everyone has kinda been with their mom since before their moms were even born. And I find that very sweet.

I finished my math college class last Saturday with a total grade of 90% and scored a 88.6% on my final!!📖🎉

I love my dad. The way we are able to bounce off each other is something special. Just us. No one else. A little bubble forms as we discuss spacetime, black holes, God, and social life. As heavy as these topics are, doing them together is light. We laugh. A lot.

We go deeper and deeper into our questions about the universe. Space feels so infinitely vast, but with my dad, it's not so scary anymore. It's fun.

I love my dad :)

Harpia harpyja

Harpy eagle are considered one of the most powerful and largest raptors globally.

The length of their rear talons is about 4-5 inches which is just the same size as the claws of a grizzly bear.

Axolotls = Coolest Animal Ever

Axolotls are my new favorite animal. The fact they can regenerate any part of their body is incredible. The science behind why they can is equally fascinating. For the longest time ever, I’ve known I wanted to major in biology in college. I think understanding why the axolotl can regenerate and the potential ways that lead to future scientific breakthroughs for humans is my new passion.
