What Has No Brain, 720 Sexes, And the Ability To Self-Heal?!

With its ability to self-heal and farm bacterial “crops,” slime mold is challenging everything we know about intelligent life.

A strange brand new organism is on display at the Parc Zoologique de Paris; a slimy, brainless organism nicknamed “Le Blob.”

Le blob is not an animal, but a slime mold—it has no eyes, no ears, no mouth, and no limbs. But Le Blog is mobile, the organism can communicate, heal itself, and it has nearly 720 biological sexes.

But what exactly is a slime mold?

Slime molds like Le Blob are protists, belonging to the phylum amoebozoa, and within the world of slime molds there are two very different kinds: cellular slime molds and acellular slime molds.

Cellular slime molds are tiny amoebas that require a microscope to see, but they can clump together into a slimy blob that acts as one whole superorganism. That’s why this kind of slime mold is sometimes called the social amoeba—they like to get together and hang out under the right conditions.

But Le Blob is the other kind of slime mold, the acellular kind. Le Blob’s official name is Physarum polycephalum and the organism still starts out as an amoeba but eventually, as it continues to grow, the nuclei divide but the cell does not essentially forming one giant cell made up of many, many nuclei called a plasmodium. And Le Blob likes to move, like a lot.

And the slime molds adventurous behavior is not the only thing that makes them special.

Find out more about this peculiar new organism and all there is to learn from slime molds like Le Blob on this Elements.

Slime Molds Remember — but Do They Learn?

“Most importantly, slime molds can be taught new tricks; depending on the species, they may not like caffeine, salt or strong light, but they can learn that no-go areas marked with these are not as bad as they seem, a process known as habituation.”

Slime Molds: No Brains, No Feet, No Problem

“When ripped in half, the halves continue to grow independently and the nuclei in each half continue to divide and develop in sync. This makes the organism uniquely appealing to cancer drug research, said Jonatha Gott at Case Western University, because it provides researchers with multiple identical samples dividing at the same time.”

Slime mould mashup models fiendish computing problem

“Enter the slime mould (Physarum polycephalum), already known to be able to solve simple mazes. The researchers, Jeff Jones and Andrew Adamatzky of the University of the West of England’s Centre for Unconventional Computing, decided to model the slime mould in a computer and see if its behaviour would provide a travelling salesman solution.”

From Earth to the Universe Documentary – When We Left Earth – Voyage Through Space and Time

Our Milky Way Galaxy is teeming with exoplanets—statistically speaking at least one for each of the hundreds of billions of stars in the galaxy. Thousands of planets have been discovered, with thousands of more planet candidates identified. Several different planet-finding techniques have matured and contribute to our present knowledge of exoplanets. Each technique has different sensitivities that favor a planet-star separation and planet mass or size range limits. Because of the selection effect, none of the current exoplanet-finding techniques can find solar system copies. Astronomers have nonetheless found a completely unexpected diversity of exoplanets, a veritable “zoo” containing many astonishing planet types.

What If We Move the Earth to a New Orbit

Did you know that the Earth’s orbit isn’t a circle, but an oval-shaped ellipse? And the length of the day is actually not 24 but 23.93 hours. We, humans, take these facts for granted. But what if one day, we had to move the entire planet to a completely new orbit and change the existing order?

Before we figure out if there’s any way to push our planet out of its orbit, let’s find out why we might need to do so! The thing is that our doomsday is approaching. Even if the planet doesn’t get overheated due to global warming, the sun will finish it off… But don’t be scared, it’s not happening tomorrow.

SUMMARY:
– The star is getting hotter and hotter as the centuries pass. And one day, about 5 billion years from now, the sun will inevitably turn into a swollen red giant. About 2 billion years later, the sun will swallow the Earth.
– Long before that, in about 1 billion years, the sun will have already grown more than 11% brighter. It’ll make the average temperature on Earth rise to at least 120 degrees F.
– Even this increase in temperature will lead to the World Ocean getting dramatically warmer. The water will start to evaporate like it does when you leave a pot of water in the sun.
– The hydrogen, which is a crucial building material for all kinds of living cells, will slowly but surely leak into space.
– If our descendants want to stay alive, they’ll have to migrate to another planet or maybe even galaxy!
– It’d still take thousands of years to deliver all the Earth’s inhabitants to their new home. Also, it’d take unimaginable amounts of fuel – even if people flew no further than to another planet in the Solar System.
– That’s why another option will likely come into play: people will have to change the orbit of the planet before the disaster strikes to avoid the tragic outcome!
– Scientists have even calculated that to keep leading a comfortable life (or at least survive), people would have to change the orbit of the planet so that it’s 9.5% further from the sun than it is now.
– At first, a mega-strong and long lasso may seem to be the simplest solution.
– But where can you find a material strong enough to carry the weight of the whole planet? Besides, how can you be sure that this asteroid will take you exactly where you need to get?
– Maybe an effective way out would be moving the planet out of its orbit with the help of a gigantic light sail?
– But once people calculate all the details, they’ll find out that the reflective disk of the light sail would have to be more than 19 times bigger than the diameter of the planet!
– An electric thruster could become a cool alternative, especially if we talk about ion drives! Come to think of it, this method could work out! And if people managed this unprecedented feat and DID change the orbit of the planet as planned, there’d be some noticeable changes.
– Our planet’s orbital speed would drop down from 18.6 to 17.7 miles per second.

Take A Journey Into The Center Of The Galaxy – How Do You Find Exoplanets?

We live in the Milky Way Galaxy, which is a collection of stars, gas, dust, and a supermassive black hole at it’s very center. Our Galaxy is a spiral galaxy, which are rotating structures that are flat (disk-like) like a DVD when looked upon edge-on. There is also a bulge in the middle that consists of mostly old stars. When you look at a spiral galaxy face-on, you can see beautiful spiral arms where stars are being born. Our solar system is in the Orion arm, and we are about 25,000 light years (2.5 X 10^17 miles) from the very center of the Galaxy.

How SpaceX’s Starship Will Become the Most Powerful Rocket in the World | Countdown to Launch

When SpaceX was founded, its goal was to establish a human colony on Mars. And Starship might be the way to get there.

In September 2019, Elon Musk unveiled the first iteration of his next-generation vehicle, Starship.

While SpaceX continues to push the limits, this next endeavor might be its most ambitious yet. SpaceX was founded with the intention of one day creating a human colony on Mars, and Elon Musk hopes that Starship and the Super Heavy rocket will be the way to get there.

Starship was built to carry 100 passengers and will serve as the spacecraft to shuttle both people and cargo to Earth’s orbit and beyond.

Starship has its six Raptors, but the real power behind this transportation system comes from the Super Heavy rocket, which has thirty-seven Raptor engines.

In its final form, the Starship and Super Heavy combination will result in the world’s most powerful launch vehicle ever developed. And SpaceX is working fast to bring this super project to life.

Find out more about SpaceX’s latest space transportation and exploration endeavor on this episode of Countdown to Launch.
