Researchers have gained new insights into dark energy and the theory of gravitation by analyzing data from the “Planck” satellite mission of the European Space Agency. Their results demonstrate that the standard model of cosmology remains an excellent description of the universe. Yet when the Planck data is combined with other astronomical observations, several deviations emerge.
An international team of researchers have developed a new way to measure the forces inside...
Researchers have assembled the largest and most accurate tree of life calibrated to time....
Over the past several decades, astronomers have come to realize that the sky is filled with magnifying glasses that allow the study of very distant and faint objects barely visible with even the largest telescopes. An astronomer has now found that one of these lenses – called an “Einstein cross”– has created four separate images of a distant supernova.
Researchers have used an advanced model to simulate in unprecedented detail the workings of "resistance-switching cells" that might replace conventional memory for electronics applications, with the potential to bring faster and higher capacity computer memory while consuming less energy.
When it comes to boiling water—or the phenomenon of applying heat to a liquid until it transitions to a gas—is there anything left for today’s scientists to study? The surprising answer is, yes, quite a bit.
ESA’s Proba-V minisatellite captures the rare sight of standing water in the arid south Australian outback. Lake Frome, one of the whitest salt lakes in the southern hemisphere is visible to the right. Unusually, this 12 February image shows it filled with brackish water that has flowed down the creeks in the area, which are typically dry.
The organizers of the inaugural ISC Cloud & Big Data conference are offering engineers and scientists in academia, industry and the government the opportunity to be a part of their new forum. Researchers in cloud computing and big data are encouraged to submit research papers, which will be presented to attendees during the conference proceedings.
A National Institutes of Health-led public-private partnership to transform and accelerate drug development achieved a significant milestone recently with the launch of a new Alzheimer’s Big Data portal — including delivery of the first wave of data — for use by the research community.
Research has for the first time analyzed over 130,000 online news articles to find out how the 2012 US presidential election played out in the media.
In 1976 several elongated comet-like objects were discovered on pictures taken with the UK Schmidt Telescope in Australia. Because of their appearance, they became known as cometary globules even though they have nothing in common with comets. The object shown in this new picture, CG4, which is also sometimes referred to as God’s Hand, is one of these cometary globules.
A relentless global effort to shrink transistors has made computers continually faster, cheaper and smaller over the last 40 years. This effort has enabled chipmakers to double the number of transistors on a chip roughly every 18 months — a trend referred to as Moore's Law. In the process, the U.S. semiconductor industry has become one of the nation's largest export industries, valued at more than $65 billion a year.
For the first time, researchers have produced a 3-D image revealing part of the inner structure of an intact, infectious virus, using a unique X-ray laser. The virus, called Mimivirus, is in a curious class of “giant viruses” discovered just over a decade ago. The experiment establishes a new technique for reconstructing the 3-D structure of many types of biological samples from a series of X-ray laser snapshots.
In the future, magnetic vortex structures — so-called skyrmions — have the potential to store and process information very efficiently. They could also be the basis for high-frequency components. For the first time, physicists have succeeded in characterizing the electromagnetic properties of insulating, semiconducting and conducting skyrmion-materials and have developed a unified theoretical description of their behavior.
Micro-drones are being put to use in a large number of areas, where these small aircraft face extensive requirements while performing aerial observation tasks or when deployed in the field of disaster management. A newly developed concept summarizes some of these challenges.
Meteorologists sometimes struggle to accurately predict the weather here on Earth, but now we can find out how cloudy it is on planets outside our solar system. MIT Researchers describe a technique that analyzes data from NASA’s Kepler space observatory to determine the types of clouds on planets that orbit other stars. Their models indicate that the clouds on Kepler-7b are most likely made from liquid rock.
This 20x photo of an ant eye received an honorable mention in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. It was taken by Noah Fram-Schwartz of Greenwich, CT, using reflected light.
This color image shows the southernmost portion of Phlegra Montes on Mars, a complex system of isolated hills, ridges and small basins that spans over 1400 kilometers from the Elysium volcanic region at about 30ºN and deep into the northern lowlands at about 50°N.
