Mesmerizing TIG Welding TIG stands for Tungsten Inert Gas. The name of the technology indicates that it uses a tungsten electrode and an inert gas. The tungsten electrode has unique properties: it melts at a temperature of around 3500 degrees Celsius and can be used with all types of aluminum and steel. #technologies @scientific

Egypt to Build the World's First Hydrogen-Powered Skyscraper The skyscraper, named the Forbes International Tower, will be the first of its kind. The main feature of this 50-story office skyscraper is its energy supply, fully powered by clean hydrogen. The building will be equipped with solar panels, providing 25% of the required electricity, while the remaining 75% will come from hydrogen fuel cells. It will be the first zero-carbon-emission skyscraper in the Middle East and North Africa. #technologies @scientific

The Planet's Big Ear If optical telescopes are called the planet's eyes, then a giant radio telescope is its enormous ear, enabling astronomers to receive radio signals from various celestial bodies. RATAN-600 is not a single structure but an entire complex of instruments spread across 282,000 square meters. It consists of 895 reflective elements, each 11.4 meters tall and 2 meters wide. These metal fragments capture signals from space. The panels are tilted at different angles to observe different parts of the sky. Additionally, the complex features five mobile observation cabins—huge movable antennas mounted on rails. #technologies @scientific

Scientists Identify the Age When Human Aging Accelerates Aging is a complex process associated with an increased risk of various diseases. In this study, researchers tracked different types of biomolecules, including RNA, proteins, lipids, and taxa of the gut, skin, nasal, and oral microbiomes. Each participant provided an average of 47 samples over 626 days, with the most committed participant contributing 367 samples. Researchers observed sharp changes in the levels of key molecules in the human body at two specific ages. At 44–45 years, the most significant changes were linked to molecules associated with fat metabolism, caffeine and alcohol processing, cardiovascular diseases, and skin and muscle dysfunction. At 60–62 years, changes were more pronounced in carbohydrate and caffeine metabolism, cardiovascular conditions, skin and muscle health, immune regulation, and kidney function. #discoveries @scientific

Vought V-173 The Vought V-173 was an experimental vertical takeoff and landing aircraft featuring a unique "circular wing" design. Powered by two Continental A-80 engines, each producing 80 horsepower, it drove large propellers that avoided ground contact during takeoff due to extended landing gear struts. The aircraft made its maiden flight in 1942. #technologies @scientific

Unusual Atmospheric Changes Observed During May Geomagnetic Storm On May 11-12, Earth witnessed spectacular auroras at unusually southern latitudes, while GPS-reliant technologies frequently malfunctioned. This event marked the strongest geomagnetic storm in 20 years. During the record-breaking magnetic storm, scientists observed: - Unpredictable movement of low-energy charged particles from equatorial regions towards auroral zones. - Charged particles divided into two groups: low-energy and high-energy particles, with the latter posing risks to astronauts and potentially damaging electronics. - Temperature and pressure fluctuations that likely led to the formation of atmospheric vortices and spirals. - Changes in distribution and positioning of low-energy particles, negatively impacting GPS, satellites, and even power grids. "As auroras intensified, more light was visible, but this also meant increased energy entering the atmosphere, making it much hotter near the poles. This heated air begins moving toward the equator," explains study author Scott England. The findings raise critical questions: "Was this geomagnetic storm truly unique, or do we now have better tools to observe such changes?" With the ongoing solar cycle, scientists anticipate similar conditions over the next two years. #discoveries @scientific

How to Express Discontent and Become More Likable This strategy works particularly well when discussing mutual friends and acquaintances. While most research on relationships focuses on romantic connections, friendships play an equally significant role. Understanding how people "compete" to win favor among friends is crucial for deeper insights into these relationships. Psychologists have found that expressing complaints can make the speaker more likable—but only if listeners don’t perceive the speaker as having hostile intentions toward the subject of criticism. Complaints can serve as a subtle tool in social competition because they aren’t immediately recognized as a competitive strategy. Researchers emphasize that competition for friends doesn't always need to be conscious. Some studies suggest that this tactic might work even better when individuals convince themselves that they aren’t competing at all. Strategically framed grievances, paired with positive intent, can not only strengthen relationships but also subtly elevate one's standing among peers. #discoveries @scientific

Laser Material Cleaning The principle of laser cleaning installations is based on the fact that the target material absorbs energy from the laser radiation, rapidly heating up, which leads to its evaporation or cracking. Meanwhile, the surface beneath it remains unaffected. #technologies @scientific

Tonight’s Sky: Supermoon and Blue Moon A supermoon occurs when the full moon or new moon coincides with the perigee—the closest approach of the Moon to Earth. This year’s first supermoon also marks the third full moon of the summer, qualifying it as a "blue supermoon." There are two types of blue moons: a calendar blue moon (the second full moon in a single month) and a seasonal blue moon (the third of four full moons in an astronomical season). Blue moons of any type occur about once every two to three years. Feel free to share your photos of the Moon in the comments! #discoveries @scientific

Ames Room Illusion The Ames room is constructed to appear, from the front, like a typical rectangular room with a flat rear wall and two parallel side walls perpendicular to the floor and ceiling. However, its actual shape is trapezoidal: the walls are slanted, and the floor and ceiling are angled. One corner of the room is significantly closer to the observer standing at the entrance than the other corner, creating a striking optical illusion. When viewed from a specific vantage point, the distorted geometry tricks the brain into perceiving the room as cubic, making objects or people in the room appear unnaturally large or small, depending on their position. #technologies @scientific
