COMSOL Server was developed specifically for running applications built with the Application Builder, which allows COMSOL Multiphysics software users to build an intuitive interface around their model that can be run by anyone — even those without prior simulation experience. Applications can be distributed throughout an organization using a Windows-native client or Web browser.

For the first time, researchers have measured large distances in the Universe using data, rather than calculations related to general relativity. The team used data from astronomical surveys to measure a standard distance that is central to our understanding of the expansion of the universe. Previously the size of this standard ruler has only been predicted from theoretical models that rely on general relativity to explain gravity.
In the same way as we now connect computers in networks through optical signals, it could also be possible to connect future quantum computers in a quantum internet. The optical signals would then consist of individual light particles or photons. One prerequisite for a working quantum internet is control of the shape of these photons. Researchers have succeeded for the first time in getting this control within the required short time.
Could there finally be tangible evidence for the existence of dark matter in the Universe? After sifting through reams of X-ray data, scientists at EPFL and Leiden University believe they could have identified the signal of a particle of dark matter. This substance, which up to now has been purely hypothetical, is run by none of the standard models of physics other than through the gravitational force.
The mystery of where Earth's water came from got murkier on December 10, 2014, when some astronomers essentially eliminated one of the chief suspects: comets. Over the past few months, the European Space Agency's Rosetta space probe closely examined the type of comet that some scientists theorized could have brought water to our planet 4 billion years ago. It found water, but the wrong kind.
What does a black hole look like up close? As the sci-fi movie Interstellar wows audiences with its computer-generated views of one of most enigmatic and fascinating phenomena in the universe, University of Arizona (UA) astrophysicists Chi-kwan Chan, Dimitrios Psaltis and Feryal Ozel are likely nodding appreciatively and saying something like, "Meh, that looks nice, but check out what we've got."
An interstellar mystery of why stars form has been solved thanks to the most realistic supercomputer simulations of galaxies yet made. Theoretical astrophysicist Philip Hopkins led research that found that stellar activity — like supernova explosions or even just starlight — plays a big part in the formation of other stars and the growth of galaxies.
World's Oldest Computer, Ancient Greek Antikythera Mechanism, 100 Years Older than Previously BelievedDecember 9, 2014 2:10 pm | by University of Puget Sound | News | Comments
An ancient Greek astronomical puzzle has one more piece in place. The new evidence results from research by James Evans, professor of physics at University of Puget Sound, and Christián Carman, history of science professor at University of Quilmes, Argentina. The two researchers published a paper advancing our understanding of the Antikythera Mechanism, an ancient Greek mechanism that modeled the known universe of 2,000 years ago.
Engineers have designed and built a prism-like device that can split a beam of light into different colors and bend the light at right angles, a development that could eventually lead to computers that use optics, rather than electricity, to carry data. The optical link is a tiny slice of silicon etched with a pattern that resembles a bar code. When a beam of light is shined at the link, two different wavelengths of light split off
Titan, Saturn’s largest moon, is a peculiar place. Unlike any other moon, it has a dense atmosphere. It has rivers and lakes made up of components of natural gas, such as ethane and methane. It also has windswept dunes that are hundreds of yards high, more than a mile wide and hundreds of miles long — despite data suggesting the body to have only light breezes.
A team of scientists has discovered an unusual form of electronic order in a new family of unconventional superconductors. The finding establishes an unexpected connection between this new group of titanium-oxypnictide superconductors and the more familiar cuprates and iron-pnictides, providing scientists with a whole new family of materials from which they can gain deeper insights into the mysteries of high-temperature superconductivity.
This 20x image is a local equalization of silicon nanocrystals in silicon dioxide taken with widefield reflection. Jan Valenta and Benjamin Bruhn of Charles University, Faculty of Mathematics and Physics (MFF) in Prague 2, Czech Republic received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope for their photo.
NASA's new Orion spacecraft made a "bull's-eye" Pacific splashdown following a dramatic journey 3,604 miles beyond Earth. The achievement opens a new era of human exploration to put people on Mars.
An experiment at the Department of Energy’s SLAC National Accelerator Laboratory provided the first fleeting glimpse of the atomic structure of a material as it entered a state resembling room-temperature superconductivity – a long-sought phenomenon in which materials might conduct electricity with 100 percent efficiency under everyday conditions.
A study of "MY Camelopardalis" binary system shows that the most massive stars are made up by merging with other smaller stars, as predicted by theoretical models.
The results of four years of observations from the ESA's Planck satellite reveals relic radiation (the most ancient light in the Universe). This light has been measured precisely across the entire sky for the first time, in both intensity and polarization, thereby producing the oldest image of the Universe. This primordial light lets us "see" some of the most elusive particles in the Universe: dark matter and relic neutrinos.
Engineers have invented a revolutionary coating material that can help cool buildings, even on sunny days, by radiating heat away from the buildings and sending it directly into space. The heart of the invention is an ultrathin, multilayered material that deals with light, both invisible and visible, in a new way.
Geckos have fascinated people for hundreds of years. Scientists have been especially intrigued by these lizards, and have studied a variety of features such as the adhesive toe pads on the underside of gecko feet with which geckos attach to surfaces with remarkable strength. One question that has captivated researchers is: Is the strength of this adhesion determined by the gecko or is it somehow intrinsic to the adhesive system?

El Niño is not a contemporary phenomenon; it’s long been the Earth’s dominant source of year-to-year climate fluctuation. But as the climate warms and the feedbacks that drive the cycle change, researchers want to know how El Niño will respond.
Researchers have discovered an invisible shield some 7,200 miles above Earth that blocks so-called killer electrons, which whip around the planet at near-light speed and have been known to threaten astronauts, fry satellites and degrade space systems during intense solar storms. The barrier to the particle motion was discovered in the Van Allen radiation belts, two doughnut-shaped rings above Earth filled with high-energy electrons and...
Following years of tests in physics laboratories, the first quantum technologies are slowly emerging into wider applications. One example is quantum cryptography — an encryption method providing an almost full guarantee of secure data transmission, currently being introduced by military forces and banking institutions.
At a White House ceremony on November 20, 2014, President Obama presented the National Medal of Science and National Medal of Technology and Innovation to individuals who have made outstanding contributions to science and engineering. The awards are the nation's highest honors for achievement and leadership in advancing the fields of science and technology.
The everyday use of a GPS device might be to find your way around town or even navigate a hiking trail; but for two physicists, the Global Positioning System might be a tool in directly detecting and measuring dark matter, so far an elusive but ubiquitous form of matter responsible for the formation of galaxies.
This 100x image of Titanium Shavings received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope.
