A man was buried in northwest China with armour consisting of more than 5,000 leather scales, a finely crafted military outfit that resembles the interlacing scales of fish; new research has shown. The armour, which resembles an apron-like waistcoat, could be donned quickly without the help of another person. Professor Patrick Wertmann of the University of Zurich's Institute of Asian and Oriental Studies described it as "lightweight, highly efficient, one size fits all defensive clothing for soldiers of a mass army." Wertmann is the study's primary researcher. Using nature as a source of inspiration for human technology was referred to as bionics by the researchers. According to study co-researcher Mayke Wagner, the scientific director of the Eurasia Department of the German Archaeological Institute and head of its Beijing office, the fish-like overlapping leather scales "strengthen the

Uranus and Neptune may experience 'diamond rain,' according to some reports

pixabay.com It's a beautiful day out there. Compared to their larger siblings, Jupiter and Saturn, Uranus and Neptune don't get nearly the attention they deserve. Uranus and Neptune appear to be dull spheres of molecules at first view. The diamond rain may be hidden beneath the world's surface, but that's just the tip of the iceberg. The farthest planets of the solar system, Uranus and Neptune, are known as "ice giants," which may conjure up images of a Tolkien-esque creature. It isn't apparent because the name has nothing to do with ice that most people associate it with, such as ice cubes in a drink. The differences in composition are what set these worlds apart. A majority of the gas giants in our solar system are composed of hydrogen and helium. These massive planets grew to their current size by rapidly accumulating these components. On the other hand, Uranus and Neptune are primarily composed of water, ammonia, and methane, respectively. These molecu

What is the process through which energy-saving light bulbs function?

pixabay.com Why have energy-saving light bulbs grown so popular, and how do they light our homes, schools and workplaces? Traditional light bulbs require 90 per cent more electricity to produce the same amount of light than energy-saving light bulbs, which were developed as a more environmentally friendly option. What's the secret? The modest light bulb has profoundly impacted human society, and it's impossible to overestimate its significance. According to the Franklin Institute, when Thomas Edison had his 'light bulb moment' and copyrighted his invention in 1879, humans lived in the dark ages. For lighting, people relied on oil or gas lamps and candles, which made the world appear considerably darker at night than it does today. As a result, we have cheap, reliable and robust lighting that can be turned on or off with a simple switch flip. They changed how we work and play after dark, influencing the design of our streets and the construction of our modern structures

England unearths 180 million-year-old sea dragon fossils

pixabay.com It's the largest and most complete specimen of its kind ever found in the United Kingdom. When this ichthyosaur lived about 180 million years ago, it would have been roughly 33 feet (10 meters) long.  An English nature reserve had discovered the remnants of a gigantic "sea dragon" that swam in the oceans 180 million years ago when dinosaurs were still living. An enormous and complete fossil of a behemoth has been unearthed in the United Kingdom. University of Manchester palaeontologist and excavation head Dean Lomax remarked in a statement that this find is "really unprecedented" and among the most significant in British palaeontological history. Although other ichthyosaurs of this type have been discovered in the United Kingdom, none has been as enormous as the one discovered recently. In the Triassic period, some 250 million years ago, ichthyosaurs were a vast group of marine reptiles that became extinct 90 million years ago, in the late Cretaceous

How radar works: The weapon that made it famous during the Second World War.

pixabay.com Even when our eyes can't see, we can see what's around us thanks to radar. The development of radar during World War II was a game-changer. Battle of Britain, the 1940 air war over British skies, was won by Britain and its allies because of technology, according to the Imperial War Museums (IWM). Radio waves are used in radar, which stands for Radio Detection and Ranging, to locate targets. According to the Earth Observing Laboratory, it is still frequently utilized today; however with the advancement of technology, they now commonly harness microwaves. More accurate readings can be obtained using radios that operate at a higher frequency. Radar was invented in the 1920s Even though this physical test by fire made radar a household name, the science that underlies it dates back much more and is based on the study of electromagnetic (EM) waves. Energy in the form of electromagnetic radiation (EM radiation) can be found in many forms, including radio waves, microwaves

The Aegean shore has uncovered the remains of a man and his dog trying to flee an ancient tsunami

pixabay.com About 3,600 years ago, a massive eruption in the Pacific Ocean called the Thera triggered massive tsunamis. Approximately 3,600 years ago, the Thera volcano in the Aegean Sea erupted, causing tremendous tsunamis that swept throughout the region. In western Turkey, archaeologists have uncovered the remains of a young man and a dog killed by a tsunami that struck the area. The northernmost evidence of the tsunamis that followed the ancient eruption and the first time fatalities have been uncovered in their archaeological environment. In the hamlet of eşme, about 40 miles west of the city of Izmer, construction workers building an apartment complex discovered Bronze Age ruins more than a decade ago. According to Vasf aholu, an archaeologist at the University of Ankara who directed the excavations from 2009 to 2019 and is the primary author of a new report on the discovery, researchers have only lately realized that tsunamis caused the destruction they saw from the Thera erupti

How much is water vapor present in the Earth's atmosphere at any time?

pixabay.com A lot of water is present in the atmosphere of our planet. Due to its abundance of water, Earth has been dubbed the "blue planet." As opposed to other planets in our solar system and possibly beyond, Earth has abundant liquid water, allowing millions upon millions of species to grow and evolve. According to the US Geological Survey, 71% of the Earth's surface is covered by water, while 96.55% of the planet's water supply is in the oceans (USGS). During the water cycle, also known as the hydrologic cycle, water does not just stay in the ground; it flows to the atmosphere. At any given time, how much water is in the atmosphere? Do we have enough in the way of what might happen if it all fell at once? Simple math tells us that there are currently several quadrillion cubic feet of water vapor in the atmosphere. If this water were to rain down in its entirety, it would wreak havoc on millions of people. The United States Geological Survey (USGS) estimates that

Can we influence the weather through geoengineering?

pixabay.com Explore how current and future geoengineering technology can control the climate. Geoengineering, according to the Oxford Geoengineering Programme, is the word used to describe the modification of weather to prevent global warming's effects on human society. Both carbon dioxide removal and solar geoengineering fall into this category. Global warming and ocean acidification can be prevented by reducing greenhouse gas emissions in Earth's stratosphere. Solar geoengineering, on the other hand, aims to return sunlight to the sun's source in space. Here are some of the geoengineering processes that have been suggested or are already in use. It is possible to regulate the weather, but should we? Despite being a topic of casual conversation, the weather and its shifting conditions significantly impact the lives of individuals, specific regions, and the entire planet. Some countries are plagued by long-term droughts, while others are always at risk of being flooded by t
