The Ancient Apple Tree Hiding in a Maine Backyard Had A Secret Nobody Expected
The apple tree looked like it was barely hanging on. Its trunk was hollow, half of it had already rotted away, and what remained leaned sideways on three twisted limbs covered in moss and blue lichen. Bigger apple trees stood nearby, making the battered specimen easy to overlook. There was nothing about it that suggested…
Earth Has Nine Critical Limits And Scientists Say Seven Are Already Crossed
Earth has nine major environmental boundaries that scientists use to track how much pressure the planet can take. A new assessment says humanity has now pushed seven of those systems beyond the limits considered safe. The latest findings include worsening climate pressure, accelerating biodiversity loss and a newly breached ocean acidification boundary. Yet there is…
Mercury Could Be Smaller Than Its Ancient Size By Miles
Mercury has been shrinking for billions of years, but scientists may have seriously underestimated how much the planet has contracted. A new analysis suggests its roughest terrain has been hiding evidence of that dramatic change. The revised estimate puts Mercury’s radial contraction between 6.9 and 11.6 kilometers. At the upper end, that could mean the…
A 1,500-Foot Tsunami Hit Alaska. Scientists Warn It Could Happen Again
The mountain gave way at 5:26 on a Sunday morning, sending more than 63 million cubic metres of rock crashing into Alaska’s Tracy Arm fjord. The impact forced the water upward with such force that it climbed 481 metres up the opposite mountainside, creating a wave roughly 1,578 feet high. Nobody died, but researchers say…
The Atlantic’s ‘Monster Web’ of Currents Could Be Heading Toward a Dangerous Collapse
Far beneath the surface of the Atlantic, a gigantic network of ocean currents is constantly moving heat, salt, carbon and oxygen around the planet. Now scientists are racing into some of the most hostile waters on Earth to determine whether this enormous system is becoming dangerously unstable, with consequences that could eventually reach the United…
Homeowner Finds Massive Viking Silver Hoard Beneath New Patio
A homeowner in Denmark thought they were about to spend a few ordinary hours preparing the ground for a new patio. Instead, a strange sound beneath the soil led to a discovery containing roughly 18.5 kilograms of Viking Age silver, making it the largest known hoard of its kind ever found in Denmark. The anonymous…
Earth Has Lost 12 Trillion Tons Of Ice In 47 Years, And Scientists Say The Melt Is Speeding Up
A staggering amount of ice has vanished from Earth’s polar regions, and the numbers are far larger than most people can imagine. Scientists have calculated that Greenland and Antarctica have lost around 12.5 trillion tons of ice since 1979, creating enough melted water to cover the entire continental United States with a layer of ice…
The Elk Who Spent 15 Minutes Trying To Save A Trapped Marmot
Nobody at the Pocatello Zoo could work out why Shooter had suddenly become obsessed with his water tank. The four-year-old bull elk kept circling it, sniffing around the edges and dipping his hooves into the water, leaving staff wondering what had caught his attention. They watched for around 15 minutes before the mystery finally became…
More Than 20 Percent Of Americas Butterflies Have Vanished In Two Decades
For every five butterflies that could have been seen across the United States in 2000, researchers estimate that only four remain today. A massive national analysis has found that butterfly abundance dropped 22% between 2000 and 2020, with some species suffering losses of more than 90%. The study brings together decades of observations from scientists…
Congress Takes On The Companies Controlling Americas Seeds
For generations, farmers could save seeds from one harvest and use them to plant the next. Now, a new congressional proposal is taking aim at the legal protections that have helped major agricultural companies control how some commercially important seeds are used. Representatives Jim McGovern and Greg Casar have introduced the Fair Seeds for Farmers…
