Fun Science

Scientists sent a robot dog to the primates to see how they would react to it. The robot came with goodies, so everything is fine👌🏻

A Text-based Neuroprosthesis has been Developed in the USA Patients were hooked up to an electrode matrix that decodes the signals controlling the vocal tract to isolate vowel and consonant sounds and then analyze patterns (templates) to predict spoken words. Researchers developed a set of 50 words necessary for everyday communication, for example, "water," "good" and "family," and then implanted a special electrode in the speech motor cortex of his brain. For testing the effectiveness of the experiment, scientists composed sentences based on the aforementioned vocabulary and displayed the results on the screen. The system had an efficiency of 18 words per minute with a recognition accuracy of 75%.

U.S. Scientists 3D-Printed Record-Sized Pieces of Human Liver The samples have been living in the laboratory for a month and perform all the functions of a normal liver. Now, they are to be sent to the ISS as NASA plans to use the new technology for future space explorers.

In the United States, a Genetically Modified Pig Kidney was Transplanted to a Human Surgeons in New York City have performed the first successful transplantation of a kidney from a genetically modified pig to a human. They stated that the organ functioned normally. The patient remained on a respirator and his brain had already died. As surgeon Robert Montgomery stated, the kidney began producing urine, waste products and creatinine almost immediately.

Animation with Underwater Internet Cable Visualization Things began with the laying of telegraph lines: the first underwater cable was laid in Munich along the Isar River, but it quickly failed due to the lack of proper waterproofing. Siemens invented adequate waterproofing in 1847, thus making it possible to lay "more serious" cables.

Water or other liquids poured into a glass will NOT reflect the image The liquid will change the refraction of the light, which can distort the image, but not horizontally.

Electromagnetic Levitation Module This simple engineering control system operates an adjustable electromagnet (copper coil) and a Hall magnetic field sensor (built into the center of the coil) to levitate the neodymium magnet and prevent it from falling.

Micra by Medtronic This is the world's smallest pacemaker to be implanted without surgery. The device is inserted into the heart by means of a catheter ("cintura") and is fixed in the right ventricle via a special mechanism. Such a device does not require open heart surgery. All manipulations are performed inside the body, without cutting into the chest. In addition to less traumatism, it also markedly reduces the risk of complications.

​​Quantum physics visually With the help of multicolored balls of quartz. They are distributed independently, each color has its own resonance.

Coldplay is Gonna Extract Electricity from Bouncing Fans What do you think of this way of generating energy? The stage is to be set up with a kinetic covering that will convert contact with the tiles into energy. The stage itself is to be built from low-carbon and recycled materials. There will also be toilets installed at concerts with flush controls. The CO2 footprint of Coldplay performances is expected to be reduced by 50 percent compared to concerts in 2016-2017, according to the band's official website.

That's How the Bendable Screens Look at the Assembly Stage No one knows yet how long it will last and how reliable it is, but it looks spectacular.

Fire ➕ Hydrogen - 👆🏻 Hydrogen gas is lighter than air and can be ignited by a flame or spark, resulting in a spectacular explosion. By the way, that’s the reason why helium, not hydrogen, is more often used to fill balloons.

Elephant Toothpaste An experiment demonstrating a multiple increase in the volume of a substance as a result of a chemical reaction. It is often performed by schools (of course, not on the same scale as the video). Such an experiment requires very few readily available reagents!

Robo-Dogs If you think robo-dogs are clumsy and slow, here's a study where scientists have trained an algorithm for certain actions, using a neural network and without any human control. Such a system allows the robo-dog to autonomously adjust different movement skills in a variety of conditions (soft surface, slippery, etc.). Also, the robot itself can get up after falling on its back.

Startling Mechanism It was invented by Brooks Walker, an engineer from San Francisco. It never made it to the masses; he only sold a few dozen of his systems.

Combinations of Magnetic Levitation and Electromagnetic Induction 👆🏻 💡 Magnetic levitation is a technology, a method of lifting an object using a magnetic field alone. Magnetic pressure is used to compensate for the acceleration of free fall or any other accelerations. 💡 Electromagnetic induction is the phenomenon of electric current, electric field or electric polarization when the magnetic field changes over time or when a material medium moves in a magnetic field.

Video Drone for Finding Fish Scientific progress has made its way to fishing. The Chinese company Chasing Innovation, a manufacturer of underwater drones, presented its next novelty - the Fish Finder Chasing F1 drone for fishermen. It is a tiny buoy-shaped vessel controlled via Wi-Fi at a distance of up to 30 meters using a mobile app.

Compact MRI Remember how cumbersome these machines used to look? Well, that will slowly become a thing of the past! We successfully completed the second phase of the POC MRI testing, the world's first mobile MRI! The device was used in the ICU in the "dirty zone" with COVID-19 patients who were diagnosed with acute neurological disorders. Best of all, the MRI machine was simply brought there as an ordinary wheelchair, so compact and handy.

Leadwood A cleaned plate of galvanized tin is immersed in a solution consisting of lead acetate and water. The surface is covered with small, dark gray crystals of lead with a metallic luster, fused together.
