The extended summer season driven by climate change has made the white Alba truffle, priced higher than gold, increasingly difficult to grow and even scarcer.The Alba truffle, or white truffle, primarily found in the town of Alba in Piedmont, Italy, is renowned for its strong aroma and unique, slightly sweet taste, with hints of garlic. Known as the "king of mushrooms" due to its high nutritional value and unmistakable fragrance, just a thin slice can elevate the flavor of any dish. This scarcity and its distinct flavor make it even pricier than lobster or gold.

During World War II, the Chrysler air raid siren was used to clear fog for aircraft operations by causing mist to coalesce into rain.The Chrysler air raid siren was massive—roughly the size of a car, measuring 3.7 meters long, 1.8 meters high, and weighing around 2.7 tons. This enormous siren was powered by a 180-horsepower, 8-cylinder gasoline engine, which drove a two-stage air compressor and a rotary chopper. The compressor pushed 73.9 cubic meters of air per minute at nearly 0.5 kg/cm² through the rotary chopper to create sound. The compressed air escaped through six giant horns at a speed of 644 km/h, generating an incredibly loud noise measured at 138 dB from 30 meters away. No other warning device could match the siren's volume.

The area surrounding the former Chernobyl nuclear power plant is now teeming with wildlife, offering a unique site for scientists to study.Almost 40 years ago, on April 26, 1986, an explosion at the Chernobyl Nuclear Power Plant in Ukraine marked a tragic event in human history. Toxic clouds spread, exposing approximately 8.4 million people to nuclear radiation, resulting in over 250,000 cancer cases and around 100,000 deaths.The Soviet Union established the 2,700-square-kilometer "Chernobyl Exclusion Zone" around the plant, erecting a fence with a 30-kilometer radius and barring public access due to contamination. Besides the ongoing human toll, the Chernobyl disaster devastated the landscape, severely impacting local wildlife and infrastructure.

Nearly 40 years after the Chernobyl nuclear disaster, entering the room that holds the "Elephant’s Foot" is still lethal, with its threat potentially persisting for centuries.Spending just 300 seconds in the same room with the "Elephant’s Foot" would mean a person has only two days left to live. This deadly object is a hardened, two-meter-wide lava-like mass formed from the melted core of Chernobyl's nuclear reactor. Due to extreme radiation levels, only a few photos of the Elephant’s Foot exist, according to the Mail.

In 1986, the Chernobyl nuclear disaster released the largest amount of radioactive material into the environment in human history. This event devastated all forms of life in the area, yet researchers are still uncovering the long-term effects of this exposure on wildlife in Ukraine today. A recent study published in Biology Letters indicates that for eastern tree frogs (Hyla orientalis), prolonged radiation exposure appears to have no significant impact on their lifespan, according to IFL Science.

Archaeologists have reconstructed the face of a young woman, buried 400 years ago, who was suspected of being a vampire.A team from Nicolaus Copernicus University in Poland discovered the remains of the woman, nicknamed "Zosia," in an unmarked cemetery. Her remains were notable for the iron sickle placed across her neck. Zosia’s left big toe was bound with a large padlock, a practice rooted in the belief that dangerous individuals possessed both good and evil sides. This measure was intended to prevent an evil spirit from escaping and turning the deceased into a vampire. Zosia, who died at around 18 to 20 years of age, likely suffered from a condition that caused fainting spells and other health issues. She is one of dozens believed by nearby villagers to be a vampire

The state of Nevada in the United States has the ideal combination of topography, climate, and geological activity to become a significant global lithium production hub.In Clayton Valley, a vast basin in Nevada’s Esmeralda County, turquoise-colored pools sit amid brown mountain ranges. Such basins and mountains stretch across the state, from west to east. However, the still waters in Clayton are man-made and rich in lithium.Silver Peak, a small former silver mining town in this remote valley, became Nevada’s first lithium production site in 1966, decades before lithium gained importance as a key metal for renewable energy and national security. The facility, run by Albemarle Corporation, produces 5,000 tons of lithium carbonate annually, according to Live Science.

American scientists have discovered that atmospheric rivers have been gradually shifting toward the poles over the past 40 years, triggering significant changes in global weather systems.Atmospheric rivers, responsible for transporting moisture across Earth’s upper atmosphere, have moved their positions in recent decades—a fundamental shift that could reshape weather patterns and precipitation levels worldwide.Research from the University of California, Santa Barbara (UCSB) reveals that atmospheric rivers in both hemispheres have shifted approximately 6° to 10° toward the poles over the past four decades. This shift means that regions affected by these atmospheric rivers now lie further north in the Northern Hemisphere and further south in the Southern Hemisphere than they previously did. The study was published in Science Advances.

Bronze Age armor was sturdy enough to protect Mycenaean warriors in battle 3,500 years ago, according to a study published on May 22 in the journal PLOS One.Researchers used a replica of the armor discovered in 1960 in Dendra, a village near the ancient Greek city of Mycenae, and enlisted 13 navy soldiers from the Greek military to test its durability.For decades, archaeologists wondered if this armor, which includes a boar-tusk helmet and a torso plate of interlocking bronze pieces, was robust enough for combat. "Since its discovery, the question has remained whether the armor was only used for ceremonial purposes or if it was meant for actual battle," said Andreas Flouris, a physiology professor at the University of Thessaly, Greece, and lead researcher. "The Dendra armor is considered one of the oldest complete sets of Bronze Age armor in Europe."

The treasure includes a gold necklace, gold crown, gold rings, and even a knife adorned with gold and semi-precious stones, all buried beside the remains of a Roman-era warrior dating back to the early 1st century, Ancient Origins reported on August 24. -
To this day, researchers have yet to uncover the location of Genghis Khan’s tomb or determine the cause of his death.The death of Genghis Khan is shrouded in mystery. He passed away in the summer of 1227 during a campaign against the Western Xia along the upper reaches of the Yellow River in Yinchuan. However, scholars still do not know how he died. One theory, recorded by Marco Polo, suggests Genghis Khan died from battle wounds inflicted by his enemies; another theory from The Secret History of the Mongols (a work written later about the Mongol royal family) claims he fell from his horse while hunting.

The tomb of Cyrus the Great, built over 2,500 years ago, is considered the oldest structure with an effective earthquake-resistant design.In ancient Greece and Persia, a construction technique was developed in which materials like clay and ceramics were placed between the ground and the foundation. This design allowed the layers to slide over one another during ground tremors, reducing earthquake damage, according to Amusing Planet. Known as base isolation, this technique remains one of the most effective methods for protecting buildings from earthquakes today. The earliest known example of base isolation is the tomb of Cyrus at Pasargadae, the capital of the Achaemenid Empire during the reign of Cyrus the Great (559-530 BC) in Iran.
