Venezuela loses all glaciers in modern times

Venezuela has become the first country in modern times to lose all its glaciers, with the last remaining glacier, the Humboldt glacier, now reclassified as an ice field. The country's glaciers have rapidly declined, with research showing a 98 percent decrease in glacial coverage between 1953 and 2019. Despite efforts by the government to cover the glacier with a blanket to protect it, the plan failed, drawing criticism from conservationists concerned about the potential contamination from the breakdown of the fabric into microplastics. This marks a tragic end for a country that once hosted cross-country skiing events in the 1950s, highlighting the devastating impact of climate change on Venezuela's natural landscape. sources

Vlogger dies live on air after eating live animals

A Chinese vlogger, known as Sun, has tragically died after live-streaming himself eating centipedes and geckos to his 15,000 followers on the DouYu platform. Sun's shocking stunt involved spinning a wheel with various bugs, foods, and drinks, and consuming whatever it landed on live on camera. The 35-year-old was found unconscious by police, with his computer still streaming, after reportedly eating venomous centipedes in a previous broadcast. While most centipedes are not deadly, some species can cause severe harm, as seen in cases of severe swelling and even death from centipede bites. Authorities are investigating Sun's death, ruling out foul play, but considering other potential causes. This incident serves as a grim reminder of the dangers of consuming live creatures for entertainment, as seen in a recent case of a man from Australia who died after eating a gecko on a dare. sources

Atmosphere detected around rocky exoplanet outside solar system

In a potential breakthrough in the search for Earth-like planets, astronomers using the James Webb Space Telescope (JWST) have detected hints of an atmosphere around the rocky exoplanet 55 Cancri e. This super-Earth, with a mass 8.8 times that of our planet, orbits its star so closely that its surface is a molten ocean of magma. If confirmed, this would be the first known rocky planet beyond our solar system to have a dense atmosphere, possibly made up of carbon dioxide or carbon monoxide. The presence of an atmosphere could explain the unexpected cooling observed on the planet's day side, indicating energy distribution from the scorching star to the dark night side. While the findings are promising, further observations are needed to fully understand the nature of 55 Cancri e. This discovery marks a significant step forward in the hunt for potentially habitable exoplanets and showcases the JWST's ability to detect atmospheres on rocky worlds. sources

Longest walkable route on Earth

The world's longest walkable route, spanning from L'Agulhas in South Africa to Magadan in Russia, covers a distance of 22,387 kilometers and crosses 16 countries, mountains, and deserts. The journey would take approximately six months of continuous walking, but realistically, completing it would be nearly impossible due to visa restrictions, war-torn regions, and natural obstacles like extreme climates. Adventurers like Karl Bushby and Paul Salopek have embarked on similar long-distance walks, facing challenges such as visa issues and slow progress. While the idea of attempting the longest walkable route may be enticing, the practicality of actually completing it remains a distant dream for most. So, if you're up for the challenge, be prepared to dedicate a significant portion of your life to the endeavor. sources

Ancient Sahara Rock Art Reveals Dramatic Environmental Changes

A recent discovery of rock art in Sudan's Atbai Desert suggests that the Sahara was a lush, green land filled with water, pastures, and animal life around 4,000 years ago. The artwork, depicting humans, antelopes, elephants, giraffes, and cattle, challenges the current hyper-arid climate of the region. Archaeologists from Macquarie University found 16 rock art sites in the area, shedding light on the drastic environmental changes that occurred in the Sahara over the past few millennia. The presence of cattle in the ancient rock art indicates a once 'green Sahara,' which was transformed by increased summer monsoon rainfall between 15,000 and 5,000 years ago. The findings, published in The Journal of Egyptian Archaeology, highlight the impact of climate change on human life and livelihood in the region. sources

Physicists speculate we live inside a black hole

Black holes, mysterious entities in space, have long puzzled scientists with their unique properties. Physicists have proposed a theory suggesting that our universe may be a holographic projection encoded at its boundary, challenging traditional views of physics. This idea stems from the black hole information paradox, where information appears to be lost when a black hole evaporates. By considering the thermodynamics of black holes in string theory, researchers have found potential solutions to this paradox, suggesting that the universe's processes could be happening at its boundary. While this theory is not widely accepted, the close relationship between the universe's observable radius and a black hole's size adds an intriguing element to the discussion. Despite the wild implications of this theory, further evidence and predictions are needed to fully support it. sources

Rare purple lump found in Roman drain, once gold-worthy

A rare and valuable lump of Tyrian purple, a dye once worth more than gold, was recently discovered in a Roman drain at a site in the UK. The discovery was made by archaeologists excavating a third-century bathhouse under the reign of Emperor Septimius Severus. Tyrian purple was a highly prized dye made from sea snails and associated with royalty and riches in ancient times. The find in Carlisle, near Hadrian's Wall, suggests a connection to the Emperor's historic visit to the area. This solid sample of Tyrian purple is a unique find in Northern Europe and provides insight into the luxurious and prestigious world of Roman imperial courts. sources

Why are Ancient Greek statues' penises small?

Ancient Greek statues are known for their small penises, but it's not just a matter of historical accuracy. While some may assume that male genitalia were smaller back then, the truth is more complex. The preference for smaller genitals in ancient Greek culture was a reflection of values surrounding male self-control and desirability. In fact, larger penises were associated with negative traits like foolishness and lust. This cultural preference for smaller genitals is evident in the removal of phalluses from classical sculptures by 19th-century curators to make them suitable for public display. Today, attitudes have shifted, and larger penises are no longer seen as unattractive. The evolution of societal values is reflected in the changing portrayal of male genitalia in art, with fig leaves and censorship giving way to more open displays of nudity. sources

Explore NASA's new black hole visualization

NASA has released a stunning new 360° visualization allowing viewers to experience what it would be like to fly around a black hole before plunging into its event horizon. Created by astrophysicist Jeremy Schnittman at NASA’s Goddard Space Flight Center, the simulation shows two scenarios - one where a camera narrowly avoids the event horizon and slingshots back out, and another where it crosses the boundary. The black hole in question is similar to Sagittarius A*, the supermassive black hole at the center of the Milky Way, with an event horizon of 25 million kilometers across. Schnittman explains that falling into a supermassive black hole is preferable to a stellar-mass one, as the former has a larger event horizon and weaker tidal forces. The visualization also demonstrates how time would be affected by the black hole's gravity, with a traveler returning younger from an orbiting trip. This captivating visualization helps to illustrate the complexities and peculiarities of black holes. sources

Human penises growing rapidly may have negative consequences

A recent study analyzing penis sizes from 1942 to 2021 has revealed a significant increase in average erect penis length over the past 30 years, while flaccid lengths remained unchanged. The meta-analysis, which included data from 55,761 males worldwide, found a 24% increase in erect length, from 12.3 centimeters to 15.2 centimeters. Lead researcher Michael Eisenberg suggests that this growth could be linked to environmental factors like chemical exposure affecting hormonal systems. While the study acknowledges potential influencing factors like measurement techniques and participant arousal state, further research is needed to understand the implications for male reproductive health. Eisenberg emphasizes the need to confirm these findings and determine the underlying causes of this rapid change in penis size. sources
