stats exam in 2 days means lots of studying today. it feels like some of this stuff we learned forever ago, but I remember the concepts way more than I thought, so this is a good sign. Means that study sessions tomorrow and Thursday will be way less heavy lifting and more so a review.
i got back from Atlanta on Saturday and am slowly getting back into the swing of things! i have some writing i'd like to get done, but other things (mostly coursework and future presentation related) are more of a priority right now. it'll all work out in the end :)
btw march flew by like 2 girlies in a nissan altima, i'm not sure how to feel

What is the difference between a cathedral and a physics lab? Are they not both saying: Hello?
Paolo Giordano, “The Solitude of Prime Numbers” / Antonio Tonelli / Laura Giplin, “A Toast to the Alchemists” / Dennis Overbye, “Music of the Heavens Turns Out to Sound a Lot Like a B Flat” / Carina Nebula / Marie Howe, “Singularity” / Alan Bean, “Is Anyone Out There?” / Bill Bryson, “A Short History of Nearly Everything” / Garrett Lee, “Canyon” / Whit Bronaugh, “The Trees That Miss The Mammoths”

to all my researchers, students and people in general who love learning: if you don't know this already, i'm about to give you a game changer
connectedpapers
the basic rundown is: you use the search bar to enter a topic, scientific paper name or DOI. the website then offers you a list of papers on the topic, and you choose the one you're looking for/most relevant one. from here, it makes a tree diagram of related papers that are clustered based on topic relatability and colour-coded by time they were produced!
for example: here i search "human B12"
Tumblr media
i go ahead and choose the first paper, meaning my graph will be based around it and start from the topics of "b12 levels" and "fraility syndrome"
Tumblr media
here is the graph output! you can scroll through all the papers included on the left, and clicking on each one shows you it's position on the chart + will pull up details on the paper on the right hand column (title, authors, citations, abstract/summary and links where the paper can be found)
you get a few free graphs a month before you have to sign up, and i think the free version gives you up to 5 a month. there are paid versions but it really depends how often you need to use this kinda thing.

THIS OCTOPUS IS HAVING A NIGHTMARE, SCIENTISTS BELIEVE.
Sleep is a fundamental biological function present in all vertebrates and most invertebrates. Octopuses are really complex animals, displaying active and inactive sleep states similar to those of vertebrates. In particular, octopuses have active sleep states during which they display sequences of camouflage patterns, while remaining relatively quiet and unresponsive to external stimuli. Some scientists have speculated that these states could be analogous to dreaming in mammals.
Now, researchers have recorder what is believing an octopuses having nightmare. During a month, researchers recorded a male Brazilian reef octopus (Octopus insularis), and they detected four brief episodes were identified during which the octopus abruptly emerged from sleep, detached itself from its sleep position, and engaged in antipredator behaviors, despite no predator was present. The longest of these episodes resembled the species-typical response to a predatory attack, suggesting that the animal may have been responding to a negative episodic memory while sleeping.
However, these are just conjectures, as it is hard to be sure, according to scientists, who claim that more studies are needed to ensure that they really are nightmares.

Thwaitesia argentiopunctata known as the sequined spider, mirror spider, or twin-peaked Thwaitesia, is a species of spider found in almost all states of Australia. It is known to have a reflective abdomen that plays a crucial role in their camouflage to protect them from predators in the forest canopy. The scales look like solid pieces of mirror glued to the spider's back, but they can actually change size depending on how threatened the spider feels. The reflective scales are composed of reflective guanine, which these and other spiders use to give themselves color. [A-Z Animals: Sequined Spider]

Supernova 1987A
The remnant of Supernova 1987A, located in a neighboring galaxy called the Large Magellanic Cloud, appears at the center of this image. The red, gaseous clouds that surround it fuel a firestorm of new star formation.

Here are some sciencey pick up lines you can use:
1. Will you be the hydrogen to my carbon.
2. You are set A and I am set B so shall we find out our common interests thru a union?
3. Shall we find out our HCF?
4. When I kiss you I expect Newton's Third Law to be in action.
5. Let's be a dipole and have dipole moments.
6. Let's be coherent, make a wavefront and make wavelets together to see our future.
7. Wanna form a mycorrhiza?
8. Your eyes shine brighter than magnesium flame (lmao what in the Apollo-)
9. Are you Ester? Cuz you lookin' fruity!
10. You are the C (cytosine) to my G (guanine).
11. If you are a proton, then I'm a neutron so let's cuddle.
12. You are the electric field to my magnetic field.
13. I can be the photon to your electron if photoelectric effect turns you on.
14. If you are alternating current, I will become the transformer, coz I will reduce your pains and increase your happiness. (My friend's)
15. You're my principal interest and you make my heart race at the rate of 100% and I'm ready to serve you every day per annum.
16. Be the glucose to my insulin receptors. (My friend's)
17. Let's spread the sheets cuz we wanna excel in what we're doing tonight. (Lmao-)
18. Let's not rush and start with induction, shall we?
19. You are my biggest flux.
20. y = mx + b my partner?
21. Be the capsaicin to my water cuz together we can be spicier. (This one is so.... 💀)

What I want to see is some sort of mathematics4science website where scientists can post mathematical problems whose solution would be helpful for said scientist's research. For instance, I would love to contribute my research efforts to solving general classes of problems which arise from biology, but not having any background in biology I don't know where to start. If someone could just tell me about some weirdly structured graphs or something, then I would be happy to take that on board and start studying it.

sturddlefish weren't supposed to exist. they were supposed to be infertile eggs but instead they hatched?? the last common ancestor between surgeon and paddlefish was 180 million years ago- that's like trying to cross a modern human with a platypus (common ancestor ~170 million years ago). it shouldn't have worked
and because the sturddlefish weren't really genetically all there (many of the eggs didn't make it very far into the development) the ones that hatched looked very different from one another

source: wikimedia
specifically, it was a cross between the Russian Sturgeon and the American Paddlefish. if you're thinking "they're both fish though" I need you to remember that "fish" is a SHAPE. just like "tree" and "crab" and "ferret" are shapes. except things have been living in the water much, much longer than they've been living on land, so "fish" have had even longer to evolve away from each other. the last time their common ancestor existed, humans and platypi hadn't even branched off from each other

Welp I've learned a hard lesson in the dangers of joining hype trains. Replication and peer review came to the conclusion that LK-99's claims of being a superconductor are false. In fact, it seems to be a worse conductor than just copper at room temperature. Summary Article
So it goes. Not the first false superconductor claim, won't be the last.

GULLS WILL DECIDE WHAT TO EAT BY WATCHING PEOPLE 
Herring gulls (Larus argentatus) can perfectly thrive in coastal  and urban landscapes, however, these birds will steal your food as soon as you are distracted. Urban gulls pay attention to human behaviour in food-related contexts, and will mimic what humans almost all the time, a new study shown.
In a simple test, researchers studied how herring gulls behave in front person eating snacks on Brighton beachfront, UK. They gave the gulls the choice between two differently coloured potato chips,  and when the human were eating potatos chips from one color, seagulls approached the food, and chose the same colour that the experimenter was eating, the 95 per cent of the time.
Seagulls were able to use human cues for stimulus enhancement and foraging decisions. Given the relatively recent history of urbanization in herring gulls, this cross-species social information transfer could be a by-product of the cognitive flexibility inherent in species who steal food, called kleptoparasitic species. This success in urban environments is suggested to result from behavioural flexibility, which is likely to require specific cognitive adaptations. In food-stealing birds, success is said to reflect an ability to integrate and use information about both the environment and other individuals, and kleptoparasites generally have usually larger relative brain sizes than their hosts.
