ESA is developing a mini-satellite to test out radically new control systems and techniques and to demonstrate drastically improved mission control capabilities that will arise when satellites can fly more powerful on-board computers. Known as Ops-Sat, it is made up of three CubeSat units with deployable solar panels. Although only 30 cm high, it contains an experimental computer 10 times more powerful than any current spacecraft.

Three Austrians have replaced injured hands with bionic ones that they can control using nerves and muscles transplanted into their arms from their legs. The men are the first to undergo what doctors refer to as "bionic reconstruction," which includes a voluntary amputation, the transplantation of nerves and muscles and learning to use faint signals from them to command the hand.
From the International Space Station, astronaut Samantha Cristoforetti took this photograph of Chicago and posted it to social media. Crewmembers on the space station photograph the Earth from their unique point of view located 200 miles above the surface as part of the Crew Earth Observations program. Photographs record how the planet is changing over time.
Plumes seen reaching high above the surface of Mars have caused a stir among scientists studying the atmosphere on the Red Planet. On two separate occasions in March and April 2012, amateur astronomers reported definite plume-like features developing on the planet. The plumes were seen rising to altitudes of over 250 kilometers on both occasions. By comparison, similar features seen in the past have not exceeded 100 kilometers.
Researchers are creating ground-breaking computer software, which has the potential to develop some of the world’s fastest supercomputers by increasing their ability to process masses of data at higher speeds than ever before. The new software has the potential to combat major global issues, including climate change and life-threatening diseases, by simulating detailed models of natural events.
Researchers gave a computer program the outline of how a magic jigsaw puzzle and a mind-reading card trick work, as well the results of experiments into how humans understand magic tricks. With this information, the system created completely new variants on those tricks which can be delivered by a magician.
This 40x photo shows a sagittal brain slice with cell nuclei and Purkinije cells expressing EGFP. It received an honorable mention in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken using confocal microscopy.
Klocwork 10.2 static code analysis software is designed to help developers write higher-quality, more secure code, faster. It integrates into desktop IDEs and into a team's natural workflow. Mirroring how code is developed, the software runs as code is being written, checking line-by-line.
We computational chemists are an impatient lot. Despite the fact that we routinely deal with highly complicated chemical processes running on our laboratory’s equally complex HPC clusters, we want answers in minutes or hours, not days, months or even years. In many instances, that’s just not feasible; in fact, there are times when the magnitude of the problem simply exceeds the capabilities of the HPC resources available to us.
In March, when researchers flip the switch to the world’s largest, most powerful particle accelerator, scientists from all over the world will be watching. Physicists expect the refurbished, higher-energy Large Hadron Collider (LHC) will build on the 2012 discovery of the Higgs particle and crack open even more mysteries of the universe
Two groups of astronomers have independently discovered a rare planet. The celestial body, called Kepler-432b, is one of the most dense and massive planets known so far. The teams report that the planet has six times the mass of Jupiter, but about the same size.
Researchers have developed a statistical technique that sorts out when changes to words’ pronunciations most likely occurred in the evolutionary history of related languages. Their model gives researchers a renewed opportunity to trace words and languages back to their earliest common ancestor or ancestors — potentially thousands of years further into prehistory than previous techniques.
Engineers at Oregon State University have completed one of the most precise evaluations yet done about the impact of a major tsunami event on the Columbia River, what forces are most important in controlling water flow and what areas might be inundated.
NASA astronaut Barry Wilmore works outside the International Space Station on the first of three spacewalks preparing the station for future arrivals by U.S. commercial crew spacecraft, on February 21, 2015. Fellow spacewalker Terry Virts, seen reflected in the visor, shared this photograph on social media.
Of course, I’m talking about the Rube Goldberg Machine Contest! This annual international competition challenges teams of students from middle school to college-age to build the most elaborate and hilarious contraption that successfully achieves the task at hand. This year’s contest is already off and running. The 2015 Task: Erase a Chalkboard.
Hypertext Transfer Protocol, HTTP, is a key component of the World Wide Web. It is the communications layer through which Web browsers request Web pages from Web servers and with which Web servers respond with the contents of the page. Like much of the internet it’s been around for decades, but a recent announcement reveals that HTTP/2, the first major update in 15 years, is about to arrive.
