In Star Trek, a transporter can teleport a person from one location to another without actually making the journey along the way. Such a transporter has fascinated many people. Quantum teleportation shares several features of the transporter and is one of the most important protocols in quantum information. Researchers proposed a scheme to create a Schrödinger's cat state in which a microorganism can be in two places at the same time.
Winter is bearing down anew, and Harvard University students have been engineering new ways to deal with it. Eighteen juniors representing several engineering disciplines in professor David Mooney's problem-solving and design class spent the fall semester inventing a robotic remote-control rooftop snowblower, a superheated icicle cutter and a freeze-resistant doormat.
NASA and NOAA satellites tracked a large winter storm that brought heavy snowfall to the U.S. Mid-Atlantic region on January 22 and 23. The low pressure area from the Eastern Pacific Ocean moved into the western U.S. and tracked across the four corners region into Texas where NASA-NOAA's Suomi NPP satellite observed the clouds associated with the storm.
Our five closest planetary neighbors are putting on a heavenly show. Starting this week, Mercury, Venus, Mars, Jupiter and Saturn are gathering together in the pre-dawn sky. It's the first time these five planets have converged like this in more than a decade. All five planets will appear together until February 20, 2016. Astronomers put optimal viewing at 45 minutes before sunrise.
A mini supercomputer that powers virtual dinosaur races has been developed to show how the world’s most powerful computers work. The compact machine — called Wee ARCHIE — takes its name from the £43m ARCHER supercomputer at the University of Edinburgh's Advanced Computing Facility. Wee ARCHIE replicates in miniature high performance computing techniques to simulate races between on-screen Argentinosaurus.
In late May 2015, the highest volcano in the Galapagos Islands erupted for the first time in 33 years. The explosive eruption at Wolf volcano on Isabela Island sent volcanic gases and ash roughly 50,000 feet into the sky, while lava flowed through a fissure, down eastern and southeastern slopes, and eventually reached the sea. In early June, the sulfur-rich lava flows on the slopes appeared to subside. This image was acquired on June 11.
Researchers have achieved critical insight into the size of neural connections, putting the memory capacity of the brain far higher than common estimates. The work also answers a longstanding question as to how the brain is so energy efficient and could help engineers build incredibly powerful, ultraprecise but energy-efficient computers, particularly ones that employ deep learning and artificial neural nets.
It is a quite extraordinary figure. Dr. Curtis Cooper from the University of Central Missouri has found the largest-known prime number — written (274207281)-1. It is around 22m digits long and, if printed in full, would take you days to read. Its discovery comes thanks to a collaborative project of volunteers who use freely available software called GIMPS (Great Internet Mersenne Prime Search) to search for primes.
This 100X photograph shows a lab-grown human mammary gland organoid. It was the 4th place winner in the 2015 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope and was taken using confocal microscopy.
A new DARPA program aims to develop an implantable neural interface able to provide unprecedented signal resolution and data-transfer bandwidth between the human brain and the digital world. The interface would serve as a translator, converting between the electrochemical language used by neurons in the brain and the ones and zeros that constitute the language of information technology.
TACC announced that the Lonestar 5 supercomputer is in full production and ready to contribute to advancing science across the state of Texas. The new Cray XC40, which contains more than 30,000 Intel Xeon processing cores from the E5-2600 v3 product family, provides a peak performance of 1.25 petaflops. With 24 processing cores per compute node, it follows the trend of more cores per node that the industry sees in every generation.
Using Mira, physicists from Princeton Plasma Physics Laboratory uncovered a new understanding about electron behavior in edge plasma. Based on this discovery, improvements were made to a well-known analytical formula that could enhance predictions of and, ultimately, increase fusion power efficiency. To develop the best predictive tools for ITER, researchers are using high-performance computing to resolve the behaviors of fusion plasma.
On January 7, the Great Internet Mersenne Prime Search (GIMPS) ― a collaborative project of volunteers who use freely available software to search for Mersenne prime numbers ― celebrated its 20th anniversary with the math discovery of the new largest known prime number. The new prime is almost 5 million digits larger than the previous record prime number, in a special class of extremely rare prime numbers known as Mersenne primes.
Interconnecting different quantum systems is important for future quantum computing architectures, but has proven difficult to achieve. Researchers have now realized a first step towards a universal quantum link based on quantum-mechanical vibrations of a nanomechanical device. It converts individual particles of light, known as photons, into quantum-mechanical vibrations, known as phonons, and then back again.
Researchers have taken a step toward achieving controlled nuclear fusion — a process that powers the Sun and other stars, and has the potential to supply the world with limitless, clean energy. The team developed a new technique to “see” where energy is delivered during a process called fast ignition. Visualizing the energy flow enabled them to test different ways to improve energy delivery to the fuel target in their experiments.
