QR codes have been used to convey information about everything from cereals to cars and new homes. But researchers think the codes have a greater potential: protecting national security. Using advanced 3-D optical imaging and extremely low light photon counting encryption, researchers have taken the ordinary QR code and transformed it into a high-end cybersecurity application to protect the integrity of computer microchips.
We all like to know our watches keep the time well, but researchers are taking precision to an entirely new dimension. The group demonstrated two cryogenically cooled optical lattice clocks that can be synchronized to a tremendous one part in 2.0 x 10-18 — meaning that they would only go out of synch by a second in 16 billion years. This is nearly 1,000 times more precise than the current international standard cesium atomic clock.
Astronomical images often look like works of art. This picture of one of our nearest neighboring galaxies, the Small Magellanic Cloud (SMC), is certainly no exception! The scene is actually a collaboration between two cosmic artists — ESA’s Herschel space observatory and NASA’s Spitzer space telescope.
Leonard Nimoy, the actor known and loved by generations of Star Trek fans as the pointy-eared, purely logical science officer Mr. Spock, has died. Nimoy died Friday of end-stage chronic obstructive pulmonary disease at his Los Angeles home, with family at his side, said his son, Adam Nimoy. He was 83.
Scientists have discovered the brightest quasar in the early universe, powered by the most massive black hole yet known at that time. The discovery of this quasar, named SDSS J0100+2802, marks an important step in understanding how quasars, the most powerful objects in the universe, have evolved from the earliest epoch, only 900 million years after the Big Bang, which is thought to have happened 13.7 billion years ago.
From the ground in this extreme northern part of Antarctica, spectacularly white and blinding ice seems to extend forever. What can't be seen is the battle raging underfoot to re-shape Earth. Water is eating away at the Antarctic ice, melting it where it hits the oceans. As the ice sheets slowly thaw, water pours into the sea — 130 billion tons per year for the past decade. That's the weight of more than 356,000 Empire State Buildings.
Pull on a piece of plastic at separate ends; it becomes thinner. So does a rubber band. One might assume tha,t when a force is applied along an axis, materials will always stretch and become thinner. Wrong. Thanks to their peculiar internal geometry, auxetic materials grow wider. After confounding scientists for decades, researchers are now developing mathematical models to explain the unusual behavior of these logic-defying materials
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.
Researchers have developed a novel three-dimensional, multiscale and multicomponent model of the endothelial cell monolayer, the inner lining of the artery, to identify the cellular mechanisms involved in cardiovascular diseases. New research based on the model is able to identify the main cellular pathways involved in the initiation and progression of the disease.
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.
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.
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 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.
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.
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.
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.
