A team of astronomers has made a groundbreaking discovery by observing the radiation belt around a dwarf star outside our solar system. This is the first time such an event has been observed outside our own planetary system. The radiation belt was detected around a very cool dwarf star about 18 light-years from Earth. This discovery is particularly interesting because the radiation belt around this dwarf star is similar in structure to the radiation belt around Jupiter. But it seemed about 10 million times brighter. The radiation belt consists of high-energy particles trapped by the magnetic field of the dwarf…

Comb jelly is known as a small and harmless marine animal at the same time. This species of animal has existed in the world for a long time. Scientists believe that they have existed since before the time of dinosaurs. On the other hand, sea sponges are also part of the oldest animals on Earth. A recent study suggests that comb jelly carries genetic material from non-animal ancestors. A remarkable feature of the body of comb jelly is that cilia hairs are located here. They accomplish hunting by releasing sticky substances. Researchers at the University of California Berkeley and the…

For most people, urine is a liquid substance that can be eliminated as quickly as possible. But for most of human history, urine was a powerful tool and an important resource. Its high ammonia content makes it an effective cleaning and bleaching agent if you let the substance go through the fermentation and evaporation process. It can also be used to make potassium nitrate known as saltpeter. It is a component of gunpowder. Fermented urine is known as “lant”. It plays an important role for military leaders. There were also instances when the government demanded that people use their liquid…

For more than ten years, Adam Hardin has been searching for precious diamonds in Arkansas’ Crater of Diamonds State Park. Although he found and sold some diamonds. He never discovered a diamond of significant value until April 10. He found the 2.38-carat brown diamond. It was the largest diamond found in Murfreesboro Park that year. Hardin named the gemstone “Frankenstone” because of its unique design. The diamond looks round. When Hardin made the remarkable discovery, he was using a technique called wet-shifting in the east drain section of the park’s 37.5-acre ‘research area’. Wet-sieving involves the use of different screens…

British startup Bellwether Industries recently released footage of the first test flight of its futuristic flying car prototype, signaling a major step forward in the automotive field where flying cars can soar through city skies. This is much needed as experts are looking at the global changes in urban lifestyles. An estimated 70% of people will live in cities by 2050 compared to today. This increased population raises concerns about increasing congestion on city roads. As a result, incidents like long journeys, traffic accidents will increase. Bellwether and other companies are banking on flying cars, and especially electric vertical takeoff…

Chinese car companies have become adept at producing high-quality, affordable electric vehicles (EVs).

The study, published April 12 in the Royal Society Open Science journal, describes the 19.6-inch-long skull and highlights its significance for understanding the dinosaur’s feeding habits, physical characteristics and relationships with other sauropods. The dinosaur skull was discovered in 2018 at the Age of Dinosaurs Museum near Winston in central Queensland. Diamantinasaurus lived in Australia…

But in reality, if someone wants to be invisible it is a big challenge. But with recent advances in technology, it seems to be easier to implement. When light strikes an object it may be absorbed or reflected. The object will appear opaque when absorbed. The light must pass through the material to achieve true transparency. Scientists are working on developing a special material called metamaterial. This will help guide the electromagnetic radiation around the object. Then makes it invisible.…
