Sand Dunes Interact And ‘Communicate’ With One Another, Physicists Say

Whether on land or underwater, sand dunes usually appear in large groups. But even when these natural formations are in close touch with their neighbours, they still need their personal space from time to time. When two identical dunes migrate over long distances, physicists have found these structures will unexpectedly change their pace so they end up evenly spread out, prompting speculation a

The World’s Only Venomous Primate Could Explain Why Humans Are Allergic to Cats

For those with a severe cat allergy, any location that harbours a pet feline can become a toxic no-go zone. Research on another tragically cute mammal now suggests this might be no accident of nature – cats really are trying to keep us away. A study on the world's only known example of a venomous primate has found a surprising similarity between a key protein in its armpit glands and the alle

Ancient Genes Reveal The Last Mammoths on Earth Were a Sickly Mess

Four thousand years ago, the last woolly mammoths quietly died on their final bastion - the isolated Wrangel Island, north of Russia in the frozen Arctic. Their demise was sudden, and strange; now, new evidence points to the mammoths themselves as partial agents of their own demise. Specifically, the mammoths (Mammuthus primigenius) were afflicted by genetic diseases, likely brought about by a

Dinosaur Eggshells Just Added Curious Evidence to a Debate About Their Blood

One of the great, longstanding mysteries in the study of dinosaurs is the question of whether the blood in those ancient, towering and sometimes terrifying frames ran hot or cold. Traditionally, it was thought that dinosaurs, like modern-day reptiles, were cold-blooded creatures. In more recent times however, growing awareness of the dinosaurian origin of birds has complicated this assumption,

The World’s Richest Man Just Pledged $10 Billion to Fight Climate Change

Jeff Bezos, founder and CEO of Amazon and the world's richest man, said Monday he was committing US$10 billion to a new fund to tackle climate change. In a post to his 1.4 million followers on Instagram, the e-commerce tycoon said the Bezos Earth Fund would "fund scientists, activists, NGOs - any effort that offers a real possibility to help preserve and protect the natural world." "Climate

NASA Has Detected Millions of Methane Hotspots Littering The Arctic

In the remote northern Arctic, greenhouse gas emissions are slipping through the icy cracks. Flying over some of the most inaccessible parts of Alaska and northwestern Canada, NASA researchers have located a shocking amount of thawing permafrost - the frozen layer of soil that blankets much of the region. If this tundra melts, it releases methane and other carbon emissions into the atmospher

Scientists Built a Genius Device That Generates Electricity ‘Out of Thin Air’

They found it buried in the muddy shores of the Potomac River more than three decades ago: a strange "sediment organism" that could do things nobody had ever seen before in bacteria. This unusual microbe, belonging to the Geobacter genus, was first noted for its ability to produce magnetite in the absence of oxygen, but with time scientists found it could make other things too, like bacterial n

I Photographed Penguins In Antarctica And They Are Cuteness Overload (10 Pics)

I spent some time in Antarctica a few weeks ago, and besides photographing landscapes, I couldn't help but document the cute penguins. I quickly got addicted to photographing them as they're just so nice to watch⁠—their amusing movements, cute interactions with little chicks, and even their funny way of walking. I could sit there and just watch them for hours. Being on the islands of Antarc

After 40 Years of Hunting, Scientists Identify a Key Flaw in Solar Panel Efficiency

Solar panels are fantastic pieces of technology, but we need to work out how to make them even more efficient – and last year, scientists solved a 40-year-old mystery around one of the key obstacles to increased efficiency. The 2019 study outlined a material defect in silicon used to produce solar cells that has previously gone undetected. It could be responsible for the 2 percent efficiency

96-årig bedstemor skal sælge sit hus –så kigger folk ind og opdager det har stået urørt i 72 år

1.  13 Nyheden om det uhørte hus spredte sig, da den 96-årige ejer til sit valgte at sælge stedet efter 72 år. En ejendomsmægler tog sagen, gik indenfor døren… og tabte kæben over det hun så.
