Ever since Einstein proposed his special theory of relativity, physics and cosmology have been based on the assumption that space looks the same in all directions — that it’s not squeezed in one direction relative to another. A new experiment used partially entangled atoms — identical to the qubits in a quantum computer — to demonstrate more precisely than ever before that this is true, to one part in a billion billion.

NASA and NOAA have provided nighttime and daytime views of the Blizzard of 2015. A combination of the day-night band and high-resolution infrared imagery showed the historic blizzard near peak intensity as it moves over the New York through Boston Metropolitan areas at 1:45 a.m. EST on January 27, 2015. Nighttime lights of the region were blurred by high cloud tops associated with the most intense parts of the storm.
This July 20, 1969, photograph of the interior view of the Apollo 11 Lunar Module shows astronaut Edwin E. “Buzz” Aldrin, Jr. during the lunar landing mission. The picture was taken by astronaut Neil A. Armstrong, commander, prior to the landing. Aldrin was the second American to set foot on the lunar surface.
Electronics and computer science researchers have helped to develop a new app to share world-class research and to receive the latest research news through a phone or tablet. The Software Sustainability Institute, a collaboration between the Universities of Southampton, Oxford, Edinburgh and Manchester, aims to spread the word about its work in promoting greater use of software in research.
This 10x photo shows a daisy petal with fungal infection and pollen grains, whole mount, unstained. It won 10th Place in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope and was taken using confocal autofluorescence.
Researchers have demonstrated that the 1935 Einstein-Podolsky-Rosen quantum mechanics paradox may be extended to more than two optical systems, paving the way for exploration of larger quantum networks. The experiment also identified properties that may be useful in establishing secure quantum communication networks where shared sequences of numbers created between two parties need to be kept secret from a third party.
Scientists using ice-penetrating radar data collected by NASA’s Operation IceBridge and earlier airborne campaigns have built the first comprehensive map of layers deep inside the Greenland Ice Sheet, opening a window on past climate conditions and the ice sheet’s potentially perilous future. This allows scientists to determine the age of large swaths of the second largest mass of ice on Earth.
After working for more than 10 years on unlocking an ancient piece of history, what lies inside damaged Herculaneum scrolls, UK Department of Computer Science Chair and Professor Brent Seales will accomplish the next step in allowing the world to read the scrolls, which cannot be physically opened. A major development in the venture, Seales is building software that will visualize the scrolls' writings as they would be if unrolled.
Researchers at Japan’s National Institute for Materials Science revealed that improvements should soon be expected in the manufacture of transistors that can be used to make flexible, paper-thin computer screens.The scientists reviewed the latest developments in research on photoactive organic field-effect transistors; devices that incorporate organic semi-conductors, amplify weak electronic signals, and either emit or receive light.
Suddenly, scientists are sexy. With Benedict Cumberbatch nominated for multiple trophies as Alan Turing and Eddie Redmayne turning heads as Stephen Hawking, young British actors playing scientists are all the rage this season. So, it's good timing for the Royal Shakespeare Company, whose new play, Oppenheimer, features John Heffernan as American scientist J. Robert Oppenheimer, leader of the team that developed the first nuclear weapon.
The speckled object depicted here is Callisto, Jupiter’s second largest moon. This image was taken in May 2001 by NASA’s Galileo spacecraft, which studied Jupiter and its moons from 1995 until 2003. Similar in appearance to a golf ball, Callisto is covered almost uniformly with pockmarks and craters across its surface, evidence of relentless collisions.
The Bulletin of the Atomic Scientists says Earth is now closer to human-caused doomsday than it has been in more than 30 years because of global warming and nuclear weaponry. But other experts say that's way too gloomy. The advocacy group, founded by the creators of the atomic bomb, moved their famed "Doomsday Clock" ahead two minutes on January 22, 2015. It said the world is now three minutes from a catastrophic midnight.
Just because concrete is the most widely used building material in human history doesn’t mean it can’t be improved. A recent study using DOE Office of Science supercomputers has led to a new way to predict concrete’s flow properties from simple measurements. The results should help accelerate the design of a new generation of high-performance and eco-friendly cement-based materials by reducing time and costs associated with R&D.
Optimization algorithms, which try to find the minimum values of mathematical functions, are everywhere in engineering. Among other things, they’re used to evaluate design tradeoffs, to assess control systems, and to find patterns in data. One way to solve a difficult optimization problem is to first reduce it to a related but much simpler problem, then gradually add complexity back in ...
NASA and Microsoft have teamed up to develop software called OnSight, a new technology that will enable scientists to work virtually on Mars using wearable technology called Microsoft HoloLens. Developed by NASA's Jet Propulsion Laboratory in Pasadena, CA, OnSight will give scientists a means to plan and, along with the Mars Curiosity rover, conduct science operations on the Red Planet.
Comet C/2014 Q2 (Lovejoy) is one of more than 32 comets imaged by NASA's NEOWISE mission from December 2013 to December 2014. This image combines a series of observations made in November 2013, when Lovejoy was 1.7 astronomical units from the sun. The image spans half of one degree. It shows the comet moving in a mostly west and slightly south direction.
Researchers who are building the highest-resolution map of the Greenland Ice Sheet to date have made a surprising discovery: two lakes of meltwater that pooled beneath the ice and rapidly drained away. One lake once held billions of gallons of water and emptied to form a mile-wide crater in just a few weeks. The other lake has filled and emptied twice in the last two years.
This 40x photo of micro algae won 17th Place in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. It was taken by Rogelio Moreno of Panama using polarized light and lambda plate.
Researchers have built a rice-grain-sized laser powered by single electrons tunneling through artificial atoms known as quantum dots. The tiny microwave laser, or "maser," is a demonstration of the fundamental interactions between light and moving electrons. The researchers built the device — which uses about one-billionth the electric current needed to power a hair dryer — while exploring how to use quantum dots.
In Silicon Valley, it's never too early to become an entrepreneur. Just ask 13-year-old Shubham Banerjee. The California eighth-grader has launched a company to develop low-cost machines to print Braille, the tactile writing system for the visually impaired. Tech giant Intel recently invested in his startup, Braigo Labs.
European Space Agency (ESA) astronaut Thomas Pesquet training for spacewalks at NASA's Johnson Space Center in Houston, USA, with ESA astronaut Luca Parmitano. Pesquet will fly to the International Space Station in 2016. Parmitano finished his six-month Volare mission in November 2013.
It turns out the Beagle has landed after all — but it never called home. The gone-but-not-forgotten spacecraft Beagle-2 went AWOL on Christmas Day, 2003, when it was supposed to land on Mars and start transmitting data back to Earth. Instead, the British-built craft went dark. After several months, it was declared lost — presumed to have been destroyed during its approach or while trying to land on the red planet.
This ghostly puff of smoke is actually a mass of swirling gas and cloud at Venus’ south pole, as seen by the Visible and Infrared Thermal Imaging Spectrometer aboard ESA’s Venus Express spacecraft. Venus has a very choppy and fast-moving atmosphere — although wind speeds are sluggish at the surface, they reach dizzying speeds of around 400 km/h at the altitude of the cloud tops, some 70 km above the surface.
This 2x photo of mouse brain vasculature won 14th Place in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. It was taken using light-sheet fluorescent microscopy.
