Based on its market share, the world’s most notorious cryptocurrency Bitcoin results in more climate damage than the production of beef and nearly as much damage as crude oil, researchers in the United States have calculated. The findings of the new three-pronged analysis suggest Bitcoin is potentially unsustainable and could have disastrous social and environmental

Planet-heating methane spewing into the atmosphere from the damaged Nord Stream pipelines only has a modest impact on climate change, say scientists, but sharply highlights the risks of fossil-fuel-driven greenhouse gas emissions. The European Union has said it believes the leaks to the strategically important pipelines, Nord Stream 1 and 2, were caused by a

Deep below the surface of our world, far beyond our feeble reach, enigmatic processes grind and roil. Every now and then, the Earth disgorges clues to their nature: tiny chthonic diamonds encasing skerricks of rare mineral. From these tiny fragments we can glean tidbits of information about our planet’s interior. A diamond recently unearthed in

More than eight months after the underwater volcano near Tonga erupted on Jan. 14, scientists are still analyzing the impacts of the violent blast, and they’re discovering that it could warm the planet. Recently, researchers calculated that the eruption of Hunga Tonga-Hunga Ha’apa spewed a staggering 50 million tons (45 million metric tons) of water

Few animals show as much affection and loyalty as dogs. But a new study offers evidence that the same human-to-animal attachment can develop in wolves, too. While earlier studies have suggested something similar, there isn’t much previous research on the attachment between wolves and humans, and the results have varied. Here, the study team wanted

Lakes appearing in Alaska because of melting permafrost are “belching” methane into the atmosphere, a scientist working with NASA said. These lakes, called thermokarsts, are so full of the climate-damaging gas that it can be seen bubbling to the surface. More and more of these lakes are appearing as Alaska’s permafrost thaws with rising temperatures

In the wacky gravitational environment in the heart of our galaxy, astronomers have found a gas blob orbiting our supermassive black hole at superspeed. Its characteristics are helping astronomers probe the space immediately surrounding Sagittarius A* in the search for answers about why the galactic center flickers and flares across the entire electromagnetic spectrum. Their

Human history has unfolded largely in bucolic settings, with sprawling savannas and forested river valleys hosting our ancestors for millions of years. By comparison, cities represent a radical new kind of habitat, one that despite its many perks often strains our mental health. Research has linked urban environments with increased risk for anxiety, depression, and

Archaeologists digging near Prague have discovered the remains of a Stone Age structure that’s older than Stonehenge and even the Egyptian pyramids: an enigmatic complex known as a roundel. Nearly 7,000 years ago during the late Neolithic, or New Stone Age, a local farming community may have gathered in this circular building, although its true

Unidentified deep-sea “blue goo” creatures recently left scientists scratching their heads after they spotted the mysterious blobs hanging out on the seafloor in the Caribbean. During a live stream of the expedition, team members discussed what the gloopy globules could be, but none of the researchers could come up with a definitive answer. Multiple blue

In 1916, Karl Schwarzchild theorized the existence of black holes as a resolution to Einstein’s field equations for his Theory of General Relativity. By the mid-20th century, astronomers began detecting black holes for the first time using indirect methods, which consisted of observing their effects on surrounding objects and space. Since the 1980s, scientists have

Have you ever wondered exactly how many ants live on Earth? Possibly not, but it’s certainly a question we’ve asked ourselves. Our research published today provides an approximate answer. We conservatively estimate our planet harbors about 20 quadrillion ants. That’s 20 thousand million millions, or in numerical form, 20,000,000,000,000,000 (20 with 15 zeroes). We further

An instrument designed to detect seismic activity on Mars has just revealed an incredibly cool new ability, detecting faint tremors from meteorites impacting the red planet. By combining data collected from the NASA’s Mars InSight lander with information from the Mars Reconnaissance Orbiter researchers have successfully linked those ground-shaking booms with freshly formed craters. Not

Burning the world’s remaining fossil fuel reserves would unleash 3.5 trillion tonnes of greenhouse gas emissions – 7 times the remaining carbon budget to cap global heating at 1.5 degrees Celsius – according to the first public inventory of hydrocarbons released Monday. ​Human activity since the Industrial Revolution, largely powered by coal, oil, and gas,

Researchers at the University of Bristol in the UK have taken a major step forward in synthetic biology by designing a system that performs several key functions of a living cell, including generating energy and expressing genes. Their artificially constructed cell even transformed from a sphere shape to a more natural amoeba-like shape over the

The idea of artificial intelligence overthrowing humankind has been talked about for decades, and in 2021, scientists delivered their verdict on whether we’d be able to control a high-level computer super-intelligence. The answer? Almost definitely not. The catch is that controlling a super-intelligence far beyond human comprehension would require a simulation of that super-intelligence which

In a recent study submitted to High Energy Astrophysical Phenomena, a team of researchers from Japan discuss strategies to observe, and possibly predict precursor signatures for an explosion from Local Type II and Galactic supernovae (SNe). This study has the potential to help us better understand both how and when supernovae could occur throughout the
