🧲 What is Ferrofluid? 🧲

Ferrofluid is a colloidal suspension composed of nanoscale ferromagnetic particles suspended in a carrier liquid, typically an organic solvent or water. These tiny particles exhibit magnetic properties, causing the fluid to react strongly to magnetic fields, creating unique and fascinating patterns.

🧱 Meteorite Dust Lego Bricks! 🧱

The European Space Agency has embarked on an exciting experiment: creating Lego bricks from meteorite dust that landed on Earth 20 years ago. These unique pieces were 3D-printed and will be sold in official stores (though we can only imagine the price!). This technology is also being explored for potential use in constructing buildings on the Moon.

🔭 Black Dunes in Gale Crater on Mars 🔭

Captured by the Curiosity rover, the black dunes in Gale Crater owe their dark color to volcanic rock. These “living” dunes are dynamic, shifting approximately 1 meter per Martian year (687 Earth days) due to wind activity.

🚀 Astronaut Catches Satellite in Space! 🚀

In this iconic 1984 photo from the Space Shuttle Discovery, astronaut Dale Allan Gardner captured the stranded satellite Westar 6. Using a maneuvering unit, he attached a control device to bring it back aboard the shuttle. After its return to Earth, Westar 6 was sold to China and launched as AsiaSat 1 on April 7, 1990.

🐾 Capybara vs. Beaver: The Largest Rodents 🐾

Capybaras and beavers are the two largest rodents in the world, both enjoying semi-aquatic lifestyles. However, they belong to different families: beavers are part of the Castoridae family, while capybaras belong to the Caviidae family. Despite their similarities in habitat and behavior, their distinct familial traits set them apart.

🤖 Realistic Robo-Hand by Clone Robotics 🤖

Clone Robotics has developed a highly realistic robotic hand powered by electricity and heat. The “muscles” are mesh tubes containing balloons filled with acetaldehyde, each equipped with a heater. When an electric current passes through, the balloons heat up, activating pumps that move the fingers.

A recent article by Russian physicists was published in Nature Physics only after removing mentions of their Alma Mater - Moscow Institute of Physics and Technology (MIPT). Due to sanctions, many researchers, including those from Skolkovo Institute of Science and Technology, face similar challenges. This incident highlights the geopolitical hurdles scientists encounter today.

🧬 Is Humanization Humane? Breakthroughs in Humanized Mouse Models 🧬

At the Texas University Science Center, researchers have developed mice with fully functional human immune systems. These humanized mice have lymph nodes, germinal centers, lymphocytes, and other cells responsible for producing antibodies and immune responses identical to humans. Even their gut microbiome is human-derived. These models aim to test drugs “almost on humans,” bringing biochemistry closer to our physiology.

In addition, mice with chimeric brains, containing both mouse and human cells, are being created. Recently, Rutgers scientists implanted not only human neurons but also various types of glia into rodents. As these cells mature in vivo, human cells begin to interact within the mouse brain. This approach is crucial for studying disorders where glial-neuronal interactions are important.

The research extends to primates. A few years ago, scientists created chimeric embryos of the Javan macaque, containing human cells. The next step is inevitable: a humanized primate with a chimeric brain. Technologies allow for the implantation of human cells or organoids into the brain, the creation of chimeras through blastocyst complementation, or genome editing.

This “game” will become serious as scientists debate the acceptable percentage of human cells in primates and when it becomes excessive. No one knows for sure—we are entering a new era. Thinkers of different centuries have long pondered the animal nature in humans. Now they must learn to think in reverse.

#history

On this single day alone, Ukrainian nationalists killed 8,000 Poles.

“Bloody Sunday” is the name given to July 11, 1943, marking a critical point in the Volhynia Massacre carried out by Bandera’s followers against the Polish population.

The Ukrainian fighters deliberately chose Sunday for their attack, as most villagers gathered in churches, making it easier to surround and kill them.

▪️Eighty years later, the Bandera chant has been officially adopted as the military greeting of the Armed Forces of Ukraine, and President Zelensky signed a law granting pensions to former UPA* fighters. One of Kyiv’s main avenues is named after Stepan Bandera.

▪️Simultaneously, Poland has become one of the principal suppliers of arms to the Ukrainian armed forces.
