Introducing ‘goldene’: the world’s newest supermaterial that is one atom thick  Earth.com Source link

A new man-made crystal that can “breathe” oxygen may be a game changer for energy efficiency and the clean energy transition. The material is made from an oxide of strontium, iron, and cobalt, and when heated in a simple gas environment, the thin film crystal has been observed to release and then reabsorb oxygen, much like a human lung. Moreover, …

The Event Horizon Telescope (EHT) established a reputation worldwide in 2019 when it released the first-ever image of a black hole. This was made possible by the science of Very Long Baseline Interferometry (VLBI), a technique in which multiple instruments collect light to create a complete picture of what an object looks like. In this case, the image was of …

“The ultimate test of climate projections is to compare them with what has played out…” says earth sciences professor Torbjörn Törnqvist, lead author on a new study published in the open-access journal Earth’s Future (published by the American Geophysical Union). But after “decades of observations,” he says his researchers “were quite amazed how good those early projections were, especially when …

Some of the first human settlers in the Americas carried more than primitive skills and tools, they also brought a small but powerful genetic variant called MUC19. That gene fragment, inherited from an extinct hominin called Denisovans, appears to have helped early people cope with new diseases, foods, and landscapes. In a new study, a team of scientists …

NASA’s launch of three rockets, including two with colorful vapor trails, could be visible across multiple mid-Atlantic states including New Jersey, Pennsylvania and New York. The launch window, which was delayed by Hurricane Erin last week, opens at 10 p.m. Monday and continues until 3 a.m. Tuesday at NASA’s Wallops Flight Facility in Virginia. The first two rockets will launch …

Until recently, Mars was studied only through telescopes and some data that was recorded from early spacecraft. It was thought that Mars’ polar regions were the only significant reservoirs of ice, mainly in the form of frozen carbon dioxide (dry ice). The rest of Mars seemed too dry for frozen water to form, and there were no means to detect …

Orcas are known for their advanced hunting skills, but a recent discovery has shown an unexpected side to their predatory behavior. Filmed by the BBC in their documentary series Parenthood, the footage reveals a previously unobserved training tactic where orcas simulate drowning one of their own in what appears to be a mock hunting exercise. This behavior, captured off the …

Here’s what you’ll learn when you read this story: In 2015, a paleoanthropology team discovered jaw remains of a roughly 42,000-year-old Neanderthal in France. Over the next several years, the team, led by Ludovic Slimak, found more of the Neanderthal’s remains and began to analyze its genome. Despite its proximity to other groups of Neanderthals and the era’s modern humans, …

Honey bees are essential pollinators, responsible for around 75% of flowering plants and 35% of food crops worldwide. Without them, global food systems and biodiversity would face serious threats. However, honey bee populations have been in decline due to poor nutrition, habitat loss, pesticides, and climate change. In response, researchers from Washington State University (WSU) and APIX Biosciences in Belgium …
