A Chinese engineer has built a quadcopter controlled by gestures โ€” the user wears a sensor controller on their wrist and can remotely control the drone like a sword.

Walmart in the U.S. is officially rolling out drone delivery โ€” couriers are gradually becoming unnecessary. Even now, drones are already delivering groceries straight to peopleโ€™s homes, like salt-and-pepper pistachios, changing the delivery market and speeding up the process of receiving orders.

A guy took a 1966 Mustang, ripped out all the internals, and swapped in the guts of a Tesla Model 3 โ€” leaving only the body and part of the retro interior.

Now, under the classic hood, thereโ€™s an electric motor and the full Tesla functionality: autopilot, summon-from-parking via the app, modern driver assists, and the complete set of Model 3 features.

The Dzhanibekov Effect, clearly demonstrated

The Dzhanibekov Effect is a strange and fascinating phenomenon that occurs when an object rotates around one of its axes in microgravity.

If you spin a nut in space, it can suddenly flip over and start rotating in a different direction. This happens because the objectโ€™s moments of inertia differ along its three axes, creating instability in its motion.

The effect was first demonstrated in orbit by cosmonaut Vladimir Dzhanibekov in 1985.

๐Ÿ’ฅSodium metal and water

Metallic sodium is one of the most active elements in the periodic table, and during contact with water it releases a large amount of energy in a short period of time, which causes it to ignite and, most often, explode.

๐ŸŒฌ The air yoke

Small magnets keep the top attached to the base, so that air flow will cause the air to spin as the air passes through the engineered turbine blades of the elegant spiral design.

๐Ÿ•ฏThe Curie point heat engine

The Curie point, or Curie temperature, is the temperature of the phase transition of kind II, associated with a jump change in the symmetry properties of matter (for example, magnetic - in ferromagnets, electrical - in ferroelectrics, crystallochemical - in ordered alloys).

๐Ÿ•ฏDiffraction spectrum candle

A thin plastic diffraction grating surrounds the flame in this rainbow design. The rainbow spectrum isn't created by refraction, as with a prism, but by diffraction, where light waves deconstructively and structurally interfere.

This CEO laid off nearly 80% of his staff because they refused to adopt AI fast enough. 2 years later, he says heโ€™d do it again

All those who do not immediately learn to integrate AI into their work processes will lose their jobs.

18 months after becoming the first human implanted with Elon Muskโ€™s brain chip, Neuralink โ€˜Participant 1โ€™ Noland Arbaugh says his whole life has changed.

"I see how the advancements in tech at this point are going to solve so many things. They are, I think, the future of medicine. I think a lot of disabilities, cures, and answers that weโ€™ve been searching for a long time will come through techโ€”and that kind of surprised me."


Itโ€™s nuts that the device holds so well for such a long time.

Aging will be defeated within 20 years. Immunologist Derya Unutmaz stated that the rejuvenation method is already ready, and it remains to wait for suitable technologies, which will appear in the next 5โ€“10 years. He added that AI will play the main role in this. As a result, aging can be reversed and 80-year-old people can be returned to the state of 20-year-olds.

"Please, do not die in the next 10 years. Try to survive this period. Because if you make it through 10 years, you will be granted another 5, and if you live 15 years, you will receive an additional 50 as a gift, because by that time we will have solved the problem of aging. Now, for the first time in human history, we have the opportunity to reverse the aging process. And we will do it. We will be able to bring 80- and even 100-year-old elders back to the biological age of 20. This is a turning point in history and possibly the most significant scientific discovery since the dawn of human civilization. Yes, of that magnitude..."

๐Ÿš€ SpaceX successfully conducted the first fully successful launch of Starship โ€” the largest rocket in history: 33 engines operated without failures, the booster separated and fell into the Gulf of Mexico, and the ship reached almost 200 km and completed all tasks, including the booster landing test and the deployment of satellite mockups.

Now Starship is ready for real work, and plans for flights to the Moon and Mars are becoming closer โ€” NASA is going to use it for the Artemis mission in 2027.
