Science by Guff  @Science: The universe as we know it. #science

As to clock nears 4:20 on 4/20(pst), we came across this @menshealthmag read reminding us all that there's science behind everything, even the munchies!! 🌯🍿🍟 Via @menshealthmag: •Studies conducted on mice have linked THC to a heightened sense of smell, which is closely related to taste. •Research has shown that sugary and fatty flavor profiles may be enhanced when THC is ingested. •We won't have a concrete understand of marijuana's affect on our appetite unless scientists are allowed to conduct meaningful research on the drug.

Have a safe 4/20 and read the full article here: https://www.menshealth.com/nutrition/amp19871266/why-does-marijuana-make-food-taste-so-good-science-has-the-answer/

Some people will go to their grave insisting that tomatoes are a fruit. For others it is, will, and always shall be, a vegetable. Everyone seems to have an opinion. How can a piece of produce be the official vegetable of New Jersey AND be the official fruit (and veg) of Arkansas? Who's right? 🤔
. ***IT'S A FRUIT***
.
Does it have seeds? 🤨 If the answer is yes, then technically - botanically - it's a fruit. This means that tomatoes are fam to apples, pears, peaches, apricots, melons and mangos. A vegetable, botanically, is any edible part of a plant that doesn’t happen to be a fruit, as in leaves (spinach), roots (turnips), stems (asparagus), tubers (potatoes), bulbs (onions), flowers (broccoli). Did you notice who's not in that family? TOMATOES. Even the canning industry identifies it as a fruit, as it's acidic enough to process in a water bath. (Yeah...THE canning industry.)
.
***IT'S A VEGETABLE***
.
In 1886, importer John Nix landed a load of West Indian tomatoes at the Port of New York where the customs official demanded payment of a ten percent tax in accordance with the Tariff Act of 1883, which levied an import duty on “foreign vegetables.” Nix, who knew his botany, objected, on the grounds that the tomato –a fruit — should be tax-exempt. The case eventually made its way to the Supreme Court where, in 1893, it was officially ruled as a vegetable. 🍅
.
From a cultural perspective, we talk about tomatoes more as a vegetable than as a fruit. At the supermarket the tomatoes are mostly in the vegetable department. Most chefs consider it a vegetable as it is more savory than sweet. Even many nutritionists label it a veg due to its low fructose amount. And horticulturalists classify the tomato as a vegetable due to the fact that it grows on a herbaceous plant. (And you don't wanna mess with the horticulturalists.)
.
So...where do you stand in the there-can-only-be-one debate about whether a tomato is a fruit or a vegetable? Are you #teamfruit or #teamvegetable? Voice your opinion using #tomatodebate and help @heinzketchup_us settle the debate at thetomatodebate.com. 🍅🍅 #ad

YES, A REAL HUMAN HEART!! ♥️♥️ (thx, @mdhealthtips!)
.
Specifically, the aortic and pulmonic valves of the heart! The heart is composed of 4 valves (the other two being the mitral and tricuspid valves) that function to regulate forward blood flow through the heart, and prevent backward flow of blood.
.
👨‍⚕️👩‍⚕️When your doctor listens to your heart through a stethoscope, what he or she is actually listening for are the normal sounds of these valves closing with each heartbeat (the aortic and pulmonic valves close together, and the tricuspid and mitral valves close together).
.
💕💗In between these normal sounds, your doctor will listen closely for abnormal heart sounds called murmurs, which are caused by turbulent (or abnormally moving) blood flow. This can be caused by a valve being too tight when its open, causing blood to squeeze through it (which we call stenosis) or by a valve that's open when it's actually supposed to be closed, allowing blood to flow backwards (called regurgitation).
.
🏥⚕️The physical exam is paramount to everyday clinical practice, and listening to the heart is just one of the many aspects of a physician's physical exam.

Have you gone for your physical this year???

During Sudan's funeral, an official said poachers should be 'jailed for life.' 📲DOUBLE-TAP IF YOU AGREE!🦏

Sudan is survived by the last two remaining of his species... his daughter Najin and granddaughter Fatu. In-vitro fertilization via preserved sperm now remains the species' only hope from complete extinction. 😢 (original post via @facts)

THE ANDROMEDA GALAXY🌌

The Andromeda Galaxy, aka Messier 31, M31, or NGC 224, is just a short 2.5 million light-years away from Earth.
We know what you're thinking, "You call that short?!?" Well, considering it's the nearest major Galaxy to the Milky Way, yes. Perspective is everything!!🎆 The Spitzer Space Telescope🔭 observed that the Andromeda Galaxy contains approximately one trillion stars✨💫 (that's more than 2x as many as our Galaxy), and we're a mere ~4.5 billion years away from an expected collision between the Milky Way and Andromeda galaxies!!! What's your favorite Galaxy???🌌 📸cred: NASA👨‍🚀

Should these boaters be scared for their lives, or is this just one mesmerizing optical illusion?? Rest easy, friends. These boaters are in no danger, as this is what's known as "forced perspective" in photography, so perfectly captured by @tomcannon.photography!! Cannon recently snapped this epicness about 3.7 miles off the coast of Western Australia in Ningaloo Reef. He and his company, Ocean Collective Media, help promote wildlife and oceanic preservation.

The largest known species of fish, Whale Sharks can grow up to 40 feet long or more, and their mouths alone can span five feet wide. But these slow-moving filter feeders, often referred to as "gentle giants," are much less intimidating than they seem.

Optical illusion or not, Whale Sharks are -- in fact -- the largest known species of fish...and if there's a larger species, they sure are good at hiding!! But just because Whale Sharks are enormous doesn't mean they're free from threats caused by humans.

It’s only Day 2 and the community response to the passing of our beloved professor is absolutely inspiring. @willandart thank you for letting us share this with our community. 🔈ON

Simply at a loss for words 😢... Perhaps our friend @neildegrassetyson said it best, "His passing has left an intellectual vacuum in his wake. But it's not empty. Think of it as a kind of vacuum energy permeating the fabric of spacetime that defies measure. Stephen Hawking, RIP Professor 1942-2018." #stephenhawking #rip

Always wanted to mix your love of sushi + science? @the_sushi_scientist has you @science fans covered!
*
To demonstrate how a signal travels from your limbs/organs to your brain, this little sushi man is going to have to go through some pain. Read below to learn more about how we feel acute pain! (Please note that “transverse” in the picture should read “thoracic”.)
*
Here the tuna nigiri 🍣 represents the skin region, or dermatome, covering the sushi man's bicep. .
*
When he gets cut with the 🔪 (sorry, it's for the science!), his peripheral nervous system becomes activated💥 in a process called "nociception." Nociception itself is not pain, just the nervous system's response to something that is potentially harmful.
*
This signal travels through sensory neurons in the periphery to pain-specific spinal cord tract(s). In this example, the signal enters through a thoracic spinal cord vertebra, the level of spinal cord associated with the bicep dermatome, passing the lumbar ones beneath.
*
Once in the spinal cord tract, the nociceptive signal travels up through the cord to the 🧠stem and the cerebrum (here, the salmon cerebrum roll).
*
A variety of 🧠 regions involved in sensation, emotion, memory/learning, and cognition work together to decide how painful the nociceptive signal is, where it's coming from in the body, and what kind of emotional response or action should happen as a result of the pain (e.g., pulling your hand away from a hot stove).
*
Basically, the experience of pain gets made in the 🧠 , and nociception happens in the neurons below.
*
If you've ever had a medical procedure under general anesthesia, you (hopefully) experienced nociception without the conscious experience of pain..

Today is International Day of Women and Girls in Science. 👩‍🔬 In the spirit of today, @Science wanted to honor Vera Rubin, an amazing American astronomer! How’s that for alliteration? She was born in Philadelphia and grew up with an interest in astronomy. Rubin eventually earned her BA in astronomy from Vassar College and tried to enroll in the graduate astronomy program at Princeton, but they refused to send her a catalogue because women weren’t allowed in the graduate astronomy program...until 1975. Let’s let that sink in for a second. She ended up studying at Cornell University, learning quantum physics from Richard Feynman and quantum mechanics under Hans Bethe. While studying the Andromeda Galaxy with fellow astronomer Kent Ford, Rubin noticed that objects on the outer parts of the galaxy were spinning at the same speed as those on the inside, which was antithetical to the belief objects at the center of a galaxy move faster than those on the outskirts. It turns out that she discovered the existence of the unseeable stuff that affects the movement of galaxies!
