Venter's Move — “Game of God" In 2010, Venter's team obtained a synthetic copy of the M. mycoides genome. Scientists transferred it to a cell from which their own DNA had been removed beforehand; the resulting mycoplasma divided and functioned properly. It was this work that the staff of the American magazine Newsweek dubbed "The Game of God." However, if it was a game, in 2016 Venter "outplayed" the Creator by reducing the original mycoplasma genome by about half and getting perfectly viable cells again. Craig Venter: "Thanks to genetic engineering, and now the field of synthetic biology, we can manipulate DNA to an unprecedented extent, just as we can edit software in a computer."

Brain Capabilities in the Future A promising and somewhat frightening method of improving brain abilities is the brain-computer interface. 🧠💡Such a system allows the brain to receive information directly from the computer. For humans, interfaces also have considerable potential, still they can also cause harm. Plus, it raises a number of ethical questions. Science fiction? A recurring problem with brain-computer interfaces is the possible emergence of "superhuman" abilities in humans. So this idea is often greeted negatively both among laymen and in scientific circles. Some fear that cyborgs will catch up with them, others afraid of interface to control the mind. And a third group sees it as a tremendous benefit to humanity, elevating human beings and society. All of these perceptions are only hypothetical. In fact, real experience with the interface is still too little. As a result, our views are based primarily on emotion: "wise disgust" or blind faith that technology can fix and improve everything.

The Rupert's drop and a hammer ⚡️ The Rupert's drop or Batavian tears are frozen droplets of tempered glass with extremely high internal mechanical stress. The main part of the droplet (head) is capable of withstanding a huge strain, but if its "tail" will be even slightly damaged, it will scatter to smithereens in a matter of seconds.

​​Acetylene Balloon Explosion 🌀Acetylene is a colorless, flammable poisonous gas with a foul odor consisting of carbon and hydrogen. Such an experiment is better not to be repeated for sure, as it would leave behind a poisonous gas. Therefore, this experience should only be carried out in the open air.

Humanoid Robots Specialized robots handle assembling cars, carrying goods, and other programs much better than humans, though they fail anything else but their narrow range of tasks. If we want the most versatile robot possible, it has to be comfortable in human environments and infrastructure, which means to be human-like — after all, a robot-cleaner cannot get a cup off a shelf, and a robot-welder will not tell you how to get to the library.

Bicycle and Electric Car Hybrid Car-eBike — the name given to the creation of the company CityQ. Such a vehicle weighs only 70 kg (with a payload of 300 kg), is able to accelerate on electric power up to 25 km/h and conquer a distance of 100 km. Moreover, it can take on board two people plus a small cargo. Economical, environmentally friendly, beneficial for health, convenient👌

Why is It Better to Do Things You Love? ☝🏻It is known that when we try and do something willingly, the prefrontal cortex works much better. The prefrontal cortex is the area of the brain responsible for motivation. Motivation increases when we engage in something we enjoy. The structure responsible for regulating emotions is deep in the brain and is called the limbic system. From it, the signals come to the prefrontal cortex, "I like doing this! I enjoy this!" Yet when the signals from the limbic system are "I don't like it!", the prefrontal cortex pretty much stops working. So motivation falls and productivity goes down.

Just an illusion👆🏻 Penrose triangle can only exist in a drawing in perspective. Still as a solid object it does not.

The Virtual Baby X Baby X is a project of the New Zealand Animation Technology Laboratory. And it is extremely different from similar developments. Scientists based on AI, neural networks and psychobiological algorithms have created a virtual girl who reacts to the world as a real child. Moreover, she observes the world around her through a camera and hears it via microphones. She is able to stare at objects and distract herself when she wants to. She even shows emotion.

Fresnel Lens That’s an optical part with a complex stepped surface. It can replace both spherical and cylindrical lenses, as well as other optical parts, such as prisms, and its steps can be delimited by concentric, spiral or linear grooves

Magnetic Levitation That kind of levitation involves a control system with adjustable electromagnet coils in a feedback loop with Hall effect sensors.

Scientists Proved that Time Can Move Backwards in Quantum Devices An international team of physicists has found that time in quantum systems can flow both forward and backward. The results of the study are described in the journal Communications Physics. According to scientific theory, with the state of superposition in quantum systems, time can move simultaneously in opposite directions, including the reversal. Scientists from Bristol (UK), Vienna (Austria) and the Balearic Islands partially proved it during a recent experiment. ☝🏻 The discovery is likely to force a revision of current concepts of time and could provide the impetus for the development of quantum mechanics and new home appliances. To measure time, the team traced entropy, the tendency of closed systems from orderliness to a state of great disorder. If a process causes a large amount of entropy, a return to the previous state becomes nearly impossible, but if it is small enough, the system can roll back in time naturally.

DNA Dating George Church, a world-renowned Harvard geneticist, told the American television channel CBS a couple of years ago that he was involved in the development of an extraordinary online dating app. 📱 It will compare a user's DNA with that of their potential partner to prevent unwanted congenital diseases in their possible children. The development was immediately called eugenics, that is, work on human selection. However, Church, in his defense, says users is to be compatible with 95% of people. In addition, the app will not give open access to any information about the genetic diseases of users. Also, the app is to only analyze information about mutations that lead to highly serious diseases like Tay-Sachs disease, which affects the central nervous system and leads to paralysis and death of a child under the age of 4.

Ubiquitous Energy – Solar Windows American company Ubiquitous Energy has developed technology that enables you to turn any glass surface into a solar panel. According to the new technology, a special organic coating of 0.001 mm is applied to the glass. It captures ultraviolet and infrared radiation, converting it into electricity, while the visible part of the spectrum passes quietly through. The developers emphasize the possibility of creating a hybrid of a simple window and a solar panel, providing homes with electricity.

​​⚡️Festo has developed the BionicKangaroo, a kangaroo-cyborg that partially recovers energy when jumping, stores it and uses for the very next jump. It's essentially a dynamo capable of recharging itself. The robot is also equipped with rubber elastic spring elements, akin to Achilles tendon — mounted on the back of the foot and on the knee joint. This artificial tendon cushions the jump, absorbs kinetic energy and releases it to jump again.

Salt and Overeating The modern food industry is based on food addiction. Such strategy relies on neurophysiology, and the baser instincts of the human body, which prevail over reason and will. The formula for success is expressed in just three words. These are "salt, sugar and fat". It is evidenced by the results of a study conducted at the Scripps Institute, when scientists fed rats either a diet of low-calorie food or gave them unlimited amounts of junk food. Soon, the latter began exhibiting compulsive eating habits and became obese after 40 days. What’s interesting, junk food effectively reorganized the pleasure centers in their brains. Just a few days of gluttony on junkfood had worn down their reward system to the core and greatly reduced their brain's natural ability to experience pleasure. Thus, they needed to consume more and more to get the same pleasure. And this is one of the signs of addiction!
