Slime Molds and Intelligence
Okay, despite going into a biology related field, I only just learned about slime molds, and hang on, because it gets WILD.
This guy in the picture is called Physarum polycephalum, one of the more commonly studied types of slime mold. It was originally thought to be a fungus, though we now know it to actually be a type of protist (a sort of catch-all group for any eukaryotic organism that isn't a plant, animal, or a fungus). As protists go, it's pretty smart. It is very good at finding the most efficient way to get to a food source, or multiple food sources. In fact, placing a slime mold on a map with food sources at all of the major cities can give a pretty good idea of an efficient transportation system. Here is a slime mold growing over a map of Tokyo compared to the actual Tokyo railway system:
Pretty good, right? Though they don't have eyes, ears, or noses, the slime molds are able to sense objects at a distance kind of like a spider using tiny differences in tension and vibrations to sense a fly caught in its web. Instead of a spiderweb, though, this organism relies on proteins called TRP channels. The slime mold can then make decisions about where it wants to grow. In one experiment, a slime mold was put in a petri dish with one glass disk on one side and 3 glass disks on the other side. Even though the disks weren't a food source, the slime mold chose to grow towards and investigate the side with 3 disks over 70% of the time.
Even more impressive is that these organisms have some sense of time. If you blow cold air on them every hour on the hour, they'll start to shrink away in anticipation when before the air hits after only 3 hours.
Now, I hear you say, this is cool and all, but like, I can do all those things too. The slime mold isn't special...
To which I would like to point out that you have a significant advantage over the slime mold, seeing as you have a brain.
Yeah, these protists can accomplish all of the things I just talked about, and they just... don't have any sort of neural architecture whatsoever? They don't even have brain cells, let alone the structures that should allow them to process sensory information and make decisions because of it. Nothing that should give them a sense of time. Scientists literally have no idea how this thing is able to "think'. But however it does, it is sure to be a form of cognition that is completely and utterly different from anything that we're familiar with.
School’s about to start in two days, does anyone have any tips for taking notes?
“Behind every exquisite thing that existed, there was something tragic.”
- Oscar Wilde, The Picture of Dorian Gray
I feel like a lot of people don't realize that studying science is connected to a lot of vocabulary.
Scientific language has its own words, rules and meanings and you have to first understand those rules and the vocabulary before you can actually understand WHAT you're studying.
You can look at a page for 5 hours- if you don't understand the name of the Protein or Molecule or Variable and the reason they are named the way they are, you won't understand the science!
So to anyone who's thinking about studying science or wants to simply understand it better, view it as a foreign language! Learn the rules and Vocabulary!
Who Was Mary W. Jackson?
On June 24, 2020, NASA announced the agency’s headquarters building in Washington, D.C., was to be named after Mary W. Jackson, the first African American female engineer at NASA.
Jackson’s story — along with those of her colleagues Katherine Johnson, Dorothy Vaughan, and Christine Darden — was popularized with the release of the “Hidden Figures” movie, based on Margot Lee Shetterly’s book by the same name.
Today, as the accomplishments of these women are brought to light, we celebrate them as Modern Figures — hidden no longer. Despite their recent recognition, we cannot forget the challenges that women and BIPOC faced and continue to face in the STEM fields.
Background
Jackson showed talent for math and science at an early age. She was born in 1921 in Hampton, Virginia, and attended the all-Black George P. Phenix Training School where she graduated with honors. She graduated from Hampton Institute (now Hampton University) in 1942 with a bachelor of science degree in both mathematics and physical sciences.
Jackson worked several jobs before arriving at the National Advisory Committee on Aeronautics (NACA), the precursor organization to NASA. She was a teacher, a receptionist, and a bookkeeper — in addition to becoming a mother — before accepting a position with the NACA Langley Aeronautical Laboratory’s segregated West Area Computers in 1951, where her supervisor was Dorothy Vaughan.
Accomplishments
After two years in West Computing, Jackson was offered a computing position to work in the 4-foot by 4-foot Supersonic Pressure Tunnel. She was also encouraged to enter a training program that would put her on track to become an engineer — however, she needed special permission from the City of Hampton to take classes in math and physics at then-segregated Hampton High School.
She completed the courses, earned the promotion, and in 1958 became NASA’s first African-American female engineer. That same year, she co-authored her first report, “Effects of Nose Angle and Mach Number on Transition on Cones at Supersonic Speeds.” By 1975, she had authored or co-authored 12 NACA and NASA technical publications — most focused on the behavior of the boundary layer of air around an airplane.
Legacy
Jackson eventually became frustrated with the lack of management opportunities for women in her field. In 1979, she left engineering to become NASA Langley’s Federal Women’s Program Manager to increase the hiring and promotion of NASA’s female mathematicians, engineers, and scientists.
Not only was she devoted to her career, Jackson was also committed to the advancement of her community. In the 1970s, she helped the students in the Hampton King Street Community Center build their own wind tunnel and run experiments. She and her husband Levi took in young professionals in need of guidance. She was also a Girl Scout troop leader for more than three decades.
Jackson retired from Langley in 1985. Never accepting the status quo, she dedicated her life to breaking barriers for minorities in her field. Her legacy reminds us that inclusion and diversity are needed to live up to NASA’s core values of teamwork and excellence.

NASA Spotlight: Astronaut Soichi Noguchi
Soichi Noguchi was selected as an astronaut with the Japan Aerospace Exploration Agency in 1996. A native of Yokohama, Kanagawa, he is currently a mission specialist for NASA’s SpaceX Crew-1 launch taking flight to the International Space Station on Nov. 14. Soichi will be the first international crewmember on Crew Dragon and the first international partner astronaut to fly aboard three types of orbital spacecraft – the U.S. space shuttle, the Russian Soyuz, and now the SpaceX Crew Dragon! Talk about impressive. He received a B.S. in Aeronautical Engineering in 1989, master’s degree in Aeronautical Engineering in 1991, Doctor of Philosophy in Advanced Interdisciplinary Studies in 2020, all from the University of Tokyo.
Soichi took time from preparing for his historic mission to answer questions about his life and career:
You recently earned a doctorate in philosophy. What made you do it?
After my second flight, I started this research about your sensory system in zero gravity. I used a my own personal video, which I took during my last two flights at the International Space Station. I had a lot of interesting discussions amongst young professionals and students at the University of Tokyo about the research. It was a fun experience – but I would not do it again!
Space is a risky business. Why do it?
Space IS definitely a risky business. But the reward is higher than the risk so that’s why we take it.
Do you have a message for boys and girls in Japan who are interested in science and engineering?
Three words: Space. Is. Waiting.
Aside from mission objectives and tasks, what’s a personal goal for this mission?
We have a lot of interesting missions to do, but my personal goal is to return home with lots of fun stories.
What was it like to get the phone call to become an astronaut?
It was 25 years ago, but I still remember the voice vividly. I got a call from Dr. Mamoru Mohri, the very first JAXA astronaut, and he said “Welcome to the Astronaut Corps.” When I got the call to be part of the Crew-1 mission, I was a lot less nervous than when I was assigned to my first mission, but the excitement remains the same.
Can you describe your crew mate Mike Hopkins in one sentence?
He is a natural leader that takes care of the team really well, and he’s fun to play around with.
Star Trek or Star Wars?
Star Wars… just because!
Can you share your favorite photo or video that you took in space?
My favorite photo is Mount Fuji because I see the mountain almost every day when I was a child. It’s definitely breathtaking to see Mount Fuji from space.
What personal items did you decide to pack for launch and why?
I have lots of family photos, and I would put it inside my sleep station. Definitely one of the most challenging things about spaceflight is not experiencing zero gravity, not the rocket, but time away from family.
How would you describe spacewalking outside the space station?
It’s an excursion. The view of the Earth is just breathtaking because you are just one glass away from the vacuum of space. There’s nothing between you and Earth.
What are you most excited about for the future of human space exploration?
I would say I’m most excited for interplanetary travel to become more common so that the school kids can go to Mars on their field trip.
What would you say to someone looking to follow in your footsteps?
Don’t worry, be happy!
How has spaceflight evolved since your first launch and stay aboard the International Space Station in 2005?
This is definitely an exciting moment. We’re starting to see more players in the game. SpaceX is the frontrunner, but soon we’ll see Boeing, Sierra Nevada and Axiom. So the International Space Station will soon have more players involved, and it will be a lot more fun!
Thank you for your time, Soichi, and good luck on your historic mission! Get to know a bit more about Soichi and his NASA astronaut crew mates Victor Glover, Michael Hopkins, and Shannon Walker in the video above.
Watch LIVE launch coverage beginning at 3:30 p.m. EST on Nov. 14 HERE.

Thanks to Mrs. Frost for having me for a 2nd year! #explorepage #STEM #STEAM #Artemis #SLS #Orion #space #spaceflight #WeAreGoing #Moon #graysongeorgia #cityofgrayson #gwinnettcounty (at Grayson, Georgia) https://www.instagram.com/p/CqCIae4OqMT/?igshid=NGJjMDIxMWI=
NASA's Neutral Buoyancy Lab: The Ultimate Underwater Simulator for Astronauts
NASA’s Neutral Buoyancy Lab (NBL) is a state-of-the-art underwater facility located in Houston, Texas. It serves as an underwater simulation environment for astronauts to train for spacewalks and other extravehicular activities (EVAs). The NBL is one of the most advanced training facilities in the world and plays a critical role in preparing astronauts for the challenges they will face in space.
The NBL is a massive indoor pool that is over 200 feet long, 100 feet wide, and 40 feet deep. It contains a full-scale mock-up of the International Space Station (ISS) and other space structures, allowing astronauts to practice and perfect their spacewalking techniques in a controlled and safe environment. The pool is filled with over 6 million gallons of water, which provides a simulated weightless experience similar to that of space.
Astronauts are equipped with a full spacewalk suit, which provides them with life support and protection from the harsh conditions of space. The suit is buoyant, which makes it difficult for astronauts to move around in water. To overcome this challenge, the suit is weighted with lead weights to balance out the buoyancy, making it possible for astronauts to move around freely in the water. This process of weight balancing is called "neutral buoyancy," which gives the NBL its name.
The NBL is not only a training facility for spacewalking, but it is also used to test new spacewalk equipment and procedures. It allows engineers and scientists to observe how equipment and procedures perform in a simulated microgravity environment. This information is then used to make improvements and ensure the safety of astronauts in space.
One of the unique features of the NBL is its ability to simulate various lighting conditions, including daylight, nighttime, and the red lighting that is used during spacewalks. This capability allows astronauts to train for all types of spacewalking scenarios and ensures that they are well-prepared for any situation they may encounter in space.
In conclusion, NASA's Neutral Buoyancy Lab is a crucial component of astronaut training and space exploration. It provides a safe and controlled environment for astronauts to train for spacewalks and other EVAs, while also allowing engineers and scientists to test new equipment and procedures. The NBL plays a vital role in ensuring the success and safety of NASA's space missions.
