There was a time when states of matter were simple: Solid, liquid, gas. Then came plasma, Bose -Einstein condensate, supercritical fluid and more. Now the list has grown by one more, with the unexpected discovery of a new state dubbed “dropletons” that bear some resemblance to liquids but occur under very different circumstances. The discovery occurred when a team at the University of Colorado Joint Institute for Lab Astrophysics were focusing laser light on gallium arsenide (GaAs) to create excitons. Excitons are formed when a photon strikes a material, particularly a semiconductor. New State of Matter Discovered
Guinness World Records has recognized Brookhaven National Laboratory 's Relativistic Heavy Ion Collider as the device which has set a new standard for achieving the "Highest Man-Made Temperature": a mind boggingly extreme 4 trillion degrees Celsius -– which is 250,000 times hotter than the center of the Sun. The heavy ion collider achieved this remarkable feat by smashing gold ions together at nearly the speed of light. The collider, which is 2.4 miles long, produced the collision — which resulted in impact energy so intense that the neutrons and protons inside the gold nuclei "melted," releasing fundamental quarks and gluons that then formed a nearly friction-free primordial plasma. A New Record for the Highest Temperature We've Ever Created: A Whopping 4 Trillion Degrees Celsius
Brookhaven National Laboratory — a passion for discovery
Physicists have created and photographed an isolated north pole — a monopole — in a simulated magnetic field, bringing to life a thought experiment that first predicted the existence of actual magnetic monopoles more than 80 years ago. In nature, north and south magnetic poles always go hand in hand. Cutting a bar magnet in half just creates two magnets, each of which still has two poles, rather than creating separate north and south poles on each half. Quantum Cloud Simulates Magnetic Monopole - Scientific American
A magnet always has a north and a south pole. Even if a magnet is cut in half down to the atomic level, magnetic fields are bipolar. However, in 1931 it was theorized that there are natural monopoles which help explain some of the peculiarities of magnetism. This has never before been tested because scientists have not been able to create monopole elementary particles in the lab that could be studied individually - until now. The research was led by David Hall of Amherst College and the results were published in Nature. Hall’s lab was able to create the monopole particles by chilling rubidium atoms to less than 100-billionths of a degree warmer than absolute zero. Synthetic magnetic monopoles have been created in the lab
I would say the future is now, but really it's almost here. ...get it? I crack myself up In all seriousness, this has SO MANY real world applications that we should get on this ASAP. Physicists say energy can be teleported 'without a limit of distance'
Yes, electrons are perfectly round -- and that's a problem I think it is possible that if we live in a world that is defined by the 11 dimensional m brane theory of string theory, dark matter and dark energy may be discovered to be properties of the brane itself (whether our universe is on the brane or is the brane has never been clear to me). That said, I'm one of the five people convinced that dark matter and dark energy are the Luminiferous aether of modern physics: constructs that are going to simply disappear when we either come up with a more advanced model or we come up with a working Unified Field theory. My other thought is that if we truly live in a multiverse, gravity may be the true 'universal' force that operates on everything in the bulk and quantum mechanics is a 'local' phenomenon. And if that's the case, it's possible they may never be reconciled. 12/21/13 12:09am

Sep. 27, 2013 — In an advance that could dramatically shrink particle accelerators for science and medicine, researchers used a laser to accelerate electrons at a rate 10 times higher than conventional technology in a nanostructured glass chip smaller than a grain of rice. The achievement was reported today in Nature by a team including scientists from the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University. "We still have a number of challenges before this technology becomes practical for real-world use, but eventually it would substantially reduce the size and cost of future high-energy particle colliders for exploring the world of fundamental particles and forces," said Joel England, the SLAC physicist who led the experiments. "It could also help enable compact accelerators and X-ray devices for security scanning, medical therapy and imaging, and research in biology and materials science."

If Time Were 2D… - From Quarks to Quasars Question: There are lots of articles written about trying to imagine a 4th dimension of space, but what would it be like to live in a universe with a 2nd dimension of time? The short answer: We simply don’t know. This question is a bit more complicated than talking about different spacial dimensions because we experience 3 dimensions of space, and so we can use what we know about life in one dimension (and how it changes when you have two dimensions) to make inferences about what 4 or more dimensions would be like. But it would be extremely difficult to imagine how things behave in 2 or 3 dimensions if we lived in a one dimensional universe (we would have nothing upon which to base our inferences).
Model describes universe with no big bang, no beginning, and no end (PhysOrg.com) -- By suggesting that mass, time, and length can be converted into one another as the universe evolves, Wun-Yi Shu has proposed a new class of cosmological models that may fit observations of the universe better than the current big bang model. What this means specifically is that the new models might explain the increasing acceleration of the universe without relying on a cosmological constant such as dark energy, as well as solve or eliminate other cosmological dilemmas such as the flatness problem and the horizon problem. Shu, an associate professor at National Tsing Hua University in Taiwan, explains in a study posted at arXiv.org that the new models emerge from a new perspective of some of the most basic entities: time, space, mass, and length.
From Quarks to Quasars
Remember that Higgs-like particle that scientists finally managed to pin down last year at the Large Hadron Collider? Well, it's proving to be a harbinger of bad news. According to Joseph Lykken, a theoretical physicist at the Fermi National Accelerator Laboratory, the mass of the Higgs boson indicates that "the universe we live in is inherently unstable, and at some point billions of years from now it's all going to get wiped out." Lykken made his statements at the recently concluded AAAS meeting in Boston, and has been subsequently reported by BBC, LiveScience, and others. The problem, says Lykken, is the potential for vacuum instability — a phenomenon that could spawn an all-consuming alternate universe within our own. An 'alternative universe' will eventually destroy ours, says Higgs researcher
Physicists have discovered a jewel-like geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality. “This is completely new and very much simpler than anything that has been done before,” said Andrew Hodges, a mathematical physicist at Oxford University who has been following the work. The revelation that particle interactions, the most basic events in nature, may be consequences of geometry significantly advances a decades-long effort to reformulate quantum field theory, the body of laws describing elementary particles and their interactions. Interactions that were previously calculated with mathematical formulas thousands of terms long can now be described by computing the volume of the corresponding jewel-like “amplituhedron,” which yields an equivalent one-term expression.
Light completely stopped for a record-breaking minute - physics-math - 25 July 2013 The fastest thing in the universe has come to a complete stop for a record-breaking minute. At full pelt, light would travel about 18 million kilometres in that time – that's more than 20 round trips to the moon. "One minute is extremely, extremely long," says Thomas Krauss at the University of St Andrews, UK. "This is indeed a major milestone." The feat could allow secure quantum communications to work over long distances.
SExpand In what could prove to be a major breakthrough in quantum memory storage and information processing, German researchers have frozen the fastest thing in the universe: light. And they did so for a record-breaking one minute. It sounds weird and it is. The reason for wanting to hold light in its place (aside from the sheer awesomeness of it) is to ensure that it retains its quantum coherence properties (i.e. its information state), thus making it possible to build light-based quantum memory. And the longer that light can be held, the better as far as computation is concerned.
The Search for Antimatter
Where does the Standard Model of physics come from? SExpand The Standard Model of particle physics is a triumph of science. It's a collection of 17 particles, and four forces. Physicists like to call it "elegant" but to the untrained eye, it looks anything but.
