Trace Dominguez | How Do Cells Know to Stop Growing at a Specific Size? @TraceDominguez | Uploaded 5 years ago | Updated 4 hours ago
Every cell in your body is a specific size. Red blood #cells, neurons, skin cells and muscle cells are all individuals, but each family of cells grows to a specific size and stops! How does our #biology tell our cells what size they want to be? This riddle has been puzzling #scientists forever, and now a new study claims to have found the answer (and it's dead simple!).
Quick note: My goal in every video is to make you *feel* something, *think* something, or *talk to a friend* about what you learned. If any of those apply to you, please consider subscribing to the channel, or sharing the video with your friends on social media! A few seconds of effort on your end really goes a long way, and thanks for even reading this paragraph, it means a lot.

P.S - I'm in Hawaii this week for vacation and scouting some future Hello Science episodes (), but I was on the SnAQ podcast last week (link below) and learned of this new research about cells.

📶 EPISODE
⏡⏡⏡⏡⏡⏡⏡⏡⏡⏡⏡⏡
Mars and the Moon are out there waiting for us to come and visit, and it’s only a matter of time. Once we go there, what happens? We can’t bring chickens to Mars, so what do we eat? Do we bring food for the entire 3-5 year mission? Do we grow food there? What happens when a short mission extends to long-term habitation? How exactly are we going to feed an off-world population?

What about to eat a vegetarian diet? Will we have cows on Mars? Whats the 2020 version of replicators from Star Trek? I have so many questions, so lets kick into it. This week I explore the evolution, economics, classism of eating meat, and where the human diet might go in #thefuture.

ISS20: Food on Space Station
https://roundupreads.jsc.nasa.gov/mobi.aspx?pageid=1483
On April 12, 1961, Soviet cosmonaut Yuri A. Gagarin made history as the first human in space aboard his Vostok capsule. During his single orbit around Earth, he also became the first person to eat in space, squeezing beef-and-liver paste from an aluminum tube into his mouth.
A Brief History of Food in Space
https://airandspace.si.edu/exhibitions/apollo-to-the-moon/online/astronaut-life/food-in-space.cfm
Explorers and travelers throughout history have had to develop methods for preserving food and carrying enough food for their journeys. This problem was especially difficult during the time when people made long sea voyages on sailing ships. Great explorers like Columbus, Magellan and Cook carried dried foods and foods preserved in salt and brine.

“If you store packaged food for a long duration the quality, flavour and nutritional quality decrease, the vitamins degrade,” she said. “We can’t guarantee that they’re going to get enough nutrition right now.”
Feeding One Million People on Mars
https://www.liebertpub.com/doi/10.1089/space.2019.0018
Food production on Mars is usually thought of in terms of growing plants to partially support small exploration crews for short- to medium-term stays. Here, we consider the more radical goal of producing enough food on Mars to sustain a permanent settlement of private citizens that increases to 1 million people within 100 Earth years.

Growing Plants in Space

NASA is looking at ways to provide astronauts with nutrients in a long-lasting, easily absorbed form—freshly grown fresh fruits and vegetables. The challenge is how to do that in a closed environment without sunlight or Earth’s gravity.

Love you, #nerdfam! Stay #curious, thank you for supporting my scicomm. Heres a challenge for your Easter egg: Try to not eat any red meat for three days. Just 72 hours without mammal meat. Try it! Let me know how it goes ✨")
