Outer Space Just Got a Little Brighter. The universe is a shade too bright.
That might be the last news you expected to hear toward the darkening end of a dark year. But that is what a band of astronomers has discovered, using cameras on the New Horizons spacecraft that once visited Pluto to measure the darkness of interplanetary space. “There’s something out there unknown,” said Tod Lauer, of the National Optical-Infrared Astronomy Research Laboratory in Tucson, Ariz.
“The universe is not completely dark, and we don’t yet completely know what it comprises.” Four billion miles from the sun, far from bright planets and the light scattered by interplanetary dust, empty space was about twice as bright as would be expected Dr. A less exciting possibility, Dr. A more intriguing, if speculative, suggestion involves what might be called cold dim matter. Dr. For the record, the amount of extra light they found bouncing around the universe is about 10 nanowatts per square meter per steradian, a measure of solid angle on the sky.
Dr. A matter of evidence.
Icist discovers strange forces acting on nanoparticles. A new scientific paper published, in part, by a University of New Mexico physicist is shedding light on a strange force impacting particles at the smallest level of the material world.
The discovery, published in Physical Review Letters, was made by an international team of researchers lead by UNM Assistant Professor Alejandro Manjavacas in the Department of Physics & Astronomy. Collaborators on the project include Francisco Rodríguez-Fortuño (King's College London, U.K.), F. Javier García de Abajo (The Institute of Photonic Sciences, Spain) and Anatoly Zayats (King's College London, U.K.). The findings relate to an area of theoretical nanophotonics and quantum theory known as the Casimir Effect, a measurable force that exists between objects inside a vacuum caused by the fluctuations of electromagnetic waves.
When studied using classical physics, the vacuum would not produce any force on the objects. Saturn's mysterious hexagon has changed from blue to gold - and no one knows why. It’s like nothing we’ve seen on any other planet in the entire Universe, and now the mysterious structure on Saturn’s north pole just got even weirder.
In just four years, Saturn’s hexagon has changed its colour from blue to gold. So far, our best guess as to why this change occurred is that this is what it looks like when Saturn's north pole gears up for next year's summer solstice. Discovered almost 30 years ago, Saturn’s hexagon is a six-sided structure that spans roughly 32,000 km (20,000 miles) in diameter, and extends about 100 km (60 miles) down into the planet’s dense atmosphere.
Researcher finds evidence that the 'world's most mysterious book' is an elaborate hoax. For hundreds of years, the world’s best cryptographers have dedicated their lives to solving the mystery of the Voynich Manuscript - a 15th century book written in a mysterious coded language that no one has ever managed to crack.
With an unknown author - and rumours that a young Leonardo da Vinci or even aliens could be behind it - the Voynich Manuscript has become the stuff of legend. But now new research suggests that the whole thing could just be one elaborate hoax. Often referred to as the world’s most mysterious book, the Voynich Manuscript is filled with what appears to be an unfamiliar language or a coded text, and is illustrated with grotesque human figures and the tendrils of other-worldly plants blooming from the borders. Since then, the book has never been replicated, and has been locked away in the vault of Yale University’s Beinecke Rare Book & Manuscript Library. Because of its age and incredible rarity, very few researchers have actually seen it in person. Rugg et. al. This sonic tractor beam costs less than $10 to make. Researchers have managed to create a sonic tractor beam that can push and pull objects using nothing but sound waves - and they did it for less than $10.
Similar to the tractor beams that drag spacecrafts on Star Trek – but on a much smaller scale – the new device uses acoustic waves to move matter through air or water in precise patterns, without having to touch them. This isn't the first time researchers have used sound waves to manipulate matter, but it is the first time it's been done so simply – and for less than the price of a lunch. Developed by engineers at the Max Planck Institute for Intelligent Systems in Germany, the tractor beam is made from just three parts (although it does require a 3D printer, too).
All you need is a 3D-printed plastic disk, a thin brass plate, and the kind of speaker you'd find in a watch alarm. "We were genuinely surprised that nobody had ever thought of this before," one of the researchers, Kai Melde, told William Herkewitz from Popular Mechanics. Quantum teleportation was just achieved over more than 7 km of city fibre. Quantum teleportation just moved out of the lab and into the real world, with two independent teams of scientists successfully sending quantum information across several kilometres of optical fibre networks in Calgary, Canada, and Hefei, China.
Physicists have mixed matter and light at room temperature for the first time. In a lovely demonstration of light's quantum effects, physicists in the UK have just mixed a molecule with light at room temperature for the first time ever.
Light and matter are usually separate, with totally distinct properties, but now scientists have trapped a particle of light - called a photon - with a molecule in a tiny, golden cage of mirrors. That's a big deal, because it creates a whole new way to manipulate the physical and chemical properties of matter, and could change the way we process quantum information. A Universe in a Nutshell: The Physics of Everything, with Michio Kaku.
Transcript My name is Professor Michio Kaku.
I’m a professor of theoretical physics at the City University of New York and I specialize in something called string theory. I’m a physicist. Some people ask me the question, “What has physics done for me lately? Human Fish' Breaks Lifespan Record. - A small cave salamander, "the human fish," has broken the world's record for longest-lived amphibian. - The salamander, which can live to over 100, is endangered, but reaches such advanced ages in zoos and protected environments. - Future studies on this amphibian might shed light on what promotes longevity in the animal kingdom.
A small cave salamander, nicknamed "the human fish" because of its human-like skin tone, has just broken the world's record for longest-lived amphibian, according to a new study. The salamander, also called olm and Proteus, has a maximum lifespan of over 100 years, concludes the new study, published in the latest Royal Society Biology Letters. Amazing chart shows the planet's longest-living animals. For humans, reaching the age of 100 is a rare milestone.
For some animals, however, it’s hardly uncommon. Not all plants and animals age the way we do, and some are built for much longer lifespans than ours. Of the 10 animals that live the longest, all of them live well past 100, according to a recent post in Disco. Dying stars could transform frozen planets into habitable worlds, astronomers find. The possibility of finding some semblance of life - whether intelligent or microbial - has been a rollercoaster of emotions of late. That 'alien megastructure' star has been one big tease (we still don’t actually know wtf is up with it though), and one team of astronomers even tried to convince us that we’ll never ever find aliens because they’re already dead - if they existed at all.
And let’s not even go into the whole Fermi Paradox that’s been looming over our heads this whole time. But astronomers from Cornell University in New York have finally given us some hope, with simulations suggesting that when giant stars like our Sun start to die out, swelling to hundreds of times their original size, they could warm up frozen planets and turn them into habitable havens for life.
"When a star ages and brightens, the habitable zone moves outward and you’re basically giving a second wind to a planetary system," said one of the team, Ramses M. Wormholes could be the key to beating the Heisenberg’s uncertainty principle, say physicists. Time travel seems much more common in science fiction than it is in reality. We’ve never met anyone from the future, after all.
But all of the physics we know indicates that wormholes - another science fiction favourite - could really be used to travel backwards in time. And according to a paper by Chinese physicists, using wormholes for time travel might actually allow us to beat Heisenberg’s uncertainty principle - described as one of the most famous (and probably misunderstood) ideas in physics - and even to solve some of the most difficult problems in computer science.
Wormholes are like portals between two places in the Universe. If you fell in one side, you’d pop out the other immediately, regardless of how far apart the two sides were. Here are the limits of humanity's space exploration. When it comes to space exploration, how far can we actually go? Is there a true limit, even with the sci-fi tech of the future, to humanity’s reach beyond Earth? As the Kurzgesagt - In a Nutshell video above explains, humanity lives in a small area of the Milky Way - an average spiral galaxy that’s about 100,000 light-years across. Like many other spiral galaxies, it's full of stars, planets, gases, and dark energy, with a supermassive black hole in the centre. Though we might think of our galaxy as crowded, most of it is actually empty space. Scaling up from there, the Milky Way and Andromeda galaxies, along with about 50 dwarf galaxies, belong to our 'local group', which spans roughly 10 million light-years.
Scientists are preparing for a solar storm so powerful, they're calling it "the big one" If a powerful enough geomagnetic solar storm erupted from the surface of the Sun, it would be capable of knocking out communications across Earth for days, months, or even years. We likely wouldn't be harmed physically by such a calamity, but there's no telling how great the impact would be on the technology we use every day, scientists warned world leaders at a recent symposium on 'space weather' in Washington, DC last week. There's no guarantee that such an event will happen while humans still walk the planet, but similarly powerful solar storms have occurred in the past – even relatively recently.
The Solar Storm of 1859 – aka the Carrington Event – was caused by an intense solar flare hitting Earth's protective magnetosphere, causing telegraph systems across the US and Europe to break down (and even giving telegraph operators electric shocks). 6 science podcasts you need to be listening to right now.

Eukaryote. Eukaryotes can reproduce both asexually through mitosis and sexually through meiosis and gamete fusion. In mitosis, one cell divides to produce two genetically identical cells. In meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells each with half the number of chromosomes as the original parent cell (haploid cells).
These act as sex cells (gametes – each gamete has just one complement of chromosomes, each a unique mix of the corresponding pair of parental chromosomes) resulting from genetic recombination during meiosis. Cell features Scientists have discovered the largest known solar system. Astronomers have found the largest known solar system, linking together a star and what was thought to be a free-floating 'lonely planet' in orbit some 1 trillion (1 million million) kilometres away from its sun. The planet, known as 2MASS J2126–8140, and its star, called TYC 9486–927–1, were both identified within the past decade, but the massive distance between them meant no one had ever considered that the pair might be related. 2MASS J2126–8140 is a gas giant about 12 to 15 times the mass of Jupiter, located about 100 light-years away from Earth. Physicists are about to test a hypothesis that could rewrite the textbooks. An international team of physicists is about to test a "sacrilegious" hypothesis about protons - one of the basic building blocks of the Universe - and the results could force a literal rewrite of nuclear physics textbooks.
