Looking skyward fills us with wonder. Off-world, the Sun, planets, stars, and galaxies all await. Our Solar System encompasses our own cosmic backyard. Farther away, stars and star clusters abound within the Milky Way. Hundreds of billions of stars exist just within our home galaxy. Inside our Local Group, only Andromeda surpasses us in mass, size, and stars. More than 5 million light-years away, galaxies abound in groups and clusters.
A team based at the University of Vienna put individual clusters of around 7,000 atoms of sodium metal some 8 nanometres wide into a superposition of different locations, each spaced 133 nanometres apart. Rather than shoot through the experimental set up like a billiard ball, each chunky cluster behaved like a wave, spreading out into a superposition of spatially distinct paths and then interfering to form a pattern researchers could detect.
It's a plant! It's a fungus! It's... an entirely new type of lifeform hitherto unknown to science? That appears to be the case for a puzzling, spire-shaped organism that lived over 400 million years ago, according to a new study published in the journal Science Advances. After analyzing its internal structures, the authors argue that the mystifying ancient beings known as prototaxites don't belong to any of the existing biological kingdoms.
The reason we can gracefully glide on an ice-skating rink or clumsily slip on an icy sidewalk is that the surface of ice is coated by a thin watery layer. Scientists generally agree that this lubricating, liquidlike layer is what makes ice slippery. They disagree, though, about why the layer forms. Three main theories about the phenomenon have been debated over the past two centuries.
Chris Buck isn't your typical home brewer - he's a virologist at the National Cancer Institute, known for discovering several human polyomaviruses, a family of viruses linked to cancers and serious infections in people with weakened immune systems. Buck's day job involves developing vaccines against these viruses, but he took things in an unexpected direction: using yeast engineered to produce viral proteins, he brewed a beer that delivered those proteins orally.
Graphene is the thinnest material yet known, composed of a single layer of carbon atoms arranged in a hexagonal lattice. That structure gives it many unusual properties that hold great promise for real-world applications: batteries, super capacitors, antennas, water filters, transistors, solar cells, and touchscreens, just to name a few. The physicists who first synthesized graphene in the lab won the 2010 Nobel Prize in Physics.
On October 1, 2022, something strange happened in the Philippines: 433 people won the jackpot in the local lottery. For this particular lotto, six numbers ranging in value from 1 to 55 were randomly selected, and the 433 winners all matched. Even more bizarre, when arranged in ascending order, the winning numbers were: 9, 18, 27, 36, 45 and 54. In other words, the winning numbers were multiples of 9 (9 1, 9 2, 9 3, etcetera).
Specifically, NASA has spent years since its successful uncrewed Artemis 1 mission studying how the extreme temperatures during reentry into the Earth's atmosphere affect Orion's heat shield. The Orion capsule sustained major damage after making its return in 2022. It cracked and chipped as a result of the extreme conditions during reentry. Over two years after the mission concluded, NASA said it had identified the root cause,
If you've ever glanced at your phone's weather app to check the day's forecast or to help plan for an upcoming storm, you've probably run across a scenario where you see an outrageous forecast. It happened to me earlier this week when I noticed my app was predicting more than 13 inches of snow for the Charlotte, NC area. Not only would that be a historic storm, but it would also be fairly apocalyptic for an area where even an inch of snow is a rarity.
Completed packs will then go into test vehicles. Solid-state batteries, which are widely considered to be the holy grail in the energy storage game, are nearing reality with every passing day. Now, Geely, Volvo's parent company, is accelerating the development of its solid-state cells, with the first completed packs expected to be fitted into working vehicles this year, as reported by China's 21 Finance.
The 91-kilometre Future Circular Collider (FCC), which would span the French-Swiss border and pass beneath Lake Geneva, is forecast to cost around 15 billion Swiss francs (US$19 billion) to make - if it gets built. The machine has the backing of the European Strategy Group, a group appointed by CERN's council to gather input from its member states and the physics community.
Now, in a recent study published in Geology, retired University of New Mexico geologist Karl Karlstrom and his colleagues conclude that the asteroid's impact shook Marble Canyon hard enough to dislodge great chunks of stone and send a landslide tumbling into the river. The debris formed a natural dam that backed up the Colorado for over 50 miles to near present-day Lees Ferry.
About ten years ago researchers across a wide range of disciplines, from forensic science and genetics to art history, got together with the goal of finding the Renaissance artist's DNA. Da Vinci had no children, and his remains were disturbed during the French Revolution. The hope is that uncovering his DNA could open the door to a number of discoveries, including new tools for authenticating artwork and potential clues about da Vinci's uncanny way of seeing the world.
Ötzi, the 5,000-something-year-old man found frozen in the Alps, did not have an easy go of it. He was probably murdered, shot from behind with an arrow that missed his vital organs and led to heavy bleeding and a prolonged and painful death. Days before his death, he fought another person in hand-to-hand combat and gashed his right hand. The more scientists have been able to study his body, the more ailments they have unveiled.
Microplastics are pervasive, found everywhere on Earth, from the Sahara Desert to patches of Arctic sea ice. Yet despite these plastic particles' ubiquity, scientists have struggled to determine exactly how many of them are in our atmosphere. Now a new estimate published in Nature suggests that land sources release about 600 quadrillion (600,000,000,000,000,000) microplastic particles into the atmosphere every year, about 20 times more than the number of particles contributed by oceans (about 26 quadrillion).
Aerospace and satellite systems manufacturer Swissto12 has secured €73m in financial support from European Space Agency (ESA) member states to accelerate Swissto12's development and industrialisation of the HummingSat space programme. Explaining its core mission, Swissto12 says it is enabling a transformational shift in the global satellite communications industry, away from legacy large, purpose-built, expensive and slow-to-deploy services towards smaller, faster, cheaper assets that leverage software-defined, reconfigurable payload architectures and agile, multi-orbit capabilities.
When we figure out what causes aging, I think we'll find it's incredibly obvious. It's not a subtle thing. The reason I say it's not a subtle thing is because all the cells in your body, you know, pretty much age at the same rate. I've never seen someone with an old left arm and a young right arm ever in my life, so why is that? There must be a clock that is synchronizing across 35 trillion cells in your body,
Three scientists have coined a rather scatological, yet revealing, term: PISS, short for Published In Support of Self. The acronym defines a disconcerting phenomenon. Specialized scientific journals that were once published every two weeks or weekly now churn out special issues every few hours. Previously, these monographs were selective and entrusted to a leading figure in a scientific discipline. Now, even the most mediocre researchers receive a flood of invitations to edit one of these countless special issues, which have become a multi-million dollar business.
The sun's rhythmic rise and fall in the sky can make it easy to forget that our star is unpredictablea roiling, burbling mass of magnetically knotted plasma that governs the entire solar system. But a new video from the European Space Agency's (ESA's) Proba-3 mission that shows a string of fountainlike explosions on the sun offers a powerful reminder of our home star's active nature.
How we handled everything all the way through ... nominal operations to this unforeseen operation really bodes well for future exploration, Fincke said. So when we're getting ready for Artemis, I am very optimistic.
Jeff Bezos's space company Blue Origin on Wednesday announced a plan to deploy 5,408 satellites in space for a communications network that will serve data centers, governments and businesses, jumping into a satellite constellation market dominated by Elon Musk's SpaceX. Deployment of satellites is planned to begin in the last quarter of 2027, Blue Origin said, adding the network will be designed to have data speeds of up to 6 Tbps anywhere on Earth.
