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.
A team of researchers is exploring new materials that could yield higher computational speeds and lower power consumption, even in harsh environments. Most modern electronic circuitry relies on controlling electronic charge within a circuit, but this control can easily be disrupted in the presence of radiation. Electronics that use spintronics may offer an alternative that is robust even in radiation-filled environments.
NASA’S Mars Atmosphere and Volatile Evolution has completed the first of five deep-dip maneuvers designed to gather measurements closer to the lower end of the Martian upper atmosphere. The 16-mile altitude difference may not seem like much, but it allows scientists to make measurements down to the top of the lower atmosphere. At these lower altitudes, the atmospheric densities are more than 10 times what they are at 93 miles.
The Nobel Prize-winning discovery of the Higgs boson — the “God particle” believed responsible for all the mass in the universe — took place in 2012 at CERN’s Large Hadron Collider. But, more than 50 years ago, the first hint of Higgs was inspired by the study of superconductors. Now, a research team has closed a circle, by reporting the first-ever observations of the Higgs mode in superconducting materials.
This 5x photo of an ant carrying its larva 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 reflected light and focus stacking.
GPU-accelerated applications have become ubiquitous in scientific supercomputing. Now, we are seeing increased adoption of GPU technology in other computationally demanding disciplines, including deep learning, one of the fastest growing areas in the machine learning and data science fields
Astronomers using the NSF's Very Large Array found surprisingly energetic activity in what they otherwise considered a "boring" galaxy, and their discovery provides important insight on how supermassive black holes can have a catastrophic effect on the galaxies in which they reside
Researchers have developed a new algorithm which increases the small time step required by ultrafast phenomena from about one attosecond to about half a femtosecond. This allows them to simulate ultrafast phenomena for systems of around 100 atoms.
This 6x photo of a pseudomorph of conichalcite after azurite 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 transmitted light.
The OpenPOWER Foundation has announced a solid lineup of speakers headlining its inaugural OpenPOWER Summit at NVIDIA’s GPU Technology Conference at the San Jose Convention Center, March 17-19, 2015. Drawing from the open development organization’s more than 100 members worldwide, the Summit’s organizers have lined up over 35 member presentations tied to the event’s “Rethink the Data Center” theme.
