Up to 50,000 tons of food waste a year won’t be going into landfills in Norway. It’ll be going into buses. How’s that? Well, the grimy grub will become transportation fuel at a new Wärtsilä-built biogas liquefaction plant outside Oslo.
A team of researchers from the University of California, Riverside Bourns College of Engineering and Russian Academy of Science have demonstrated a new type of holographic memory device that could provide unprecedented data storage capacity and data processing capabilities in electronic devices.
The future of computing may lie not in electrons, but in photons – that is, in microprocessors that use light instead of electrical signals. But these so-called photonic devices are typically built using customized methods that make them difficult and expensive to manufacture.
A new bioprinting method developed at the Wyss Institute for Biologically Inspired Engineering at Harvard University and the Harvard School of Engineering and Applied Sciences (SEAS) creates intricately patterned 3D tissue constructs with multiple types of cells and tiny blood vessels. The work represents a major step toward a longstanding goal of tissue engineers: creating human tissue constructs realistic enough to test drug safety and effectiveness.
Terrain that NASA's Curiosity Mars rover is now crossing is as smooth as team members had anticipated based on earlier images from orbit. On Tuesday, Feb. 18, the rover covered 329 feet (100.3 meters), the mission's first long trek that used reverse driving and its farthest one-day advance of any kind in more than three months.
Picture a single cloud large enough to span the solar system from the sun to beyond Pluto's orbit. Now imagine many such clouds orbiting in a vast ring at the heart of a distant galaxy, occasionally dimming the X-ray light produced by the galaxy's monster black hole.
One of the biggest mysteries in astronomy, how stars blow up in supernova explosions, finally is being unraveled with the help of NASA's Nuclear Spectroscopic Telescope Array (NuSTAR).
Duckweed is a tiny floating plant that's been known to drive people daffy. It's one of the smallest and fastest-growing flowering plants that often becomes a hard-to-control weed in ponds and small lakes. But it's also been exploited to clean contaminated water and as a source to produce pharmaceuticals.
New technology to capture the kinetic energy of our everyday movements, such as walking, and to convert it into electrical energy has come a step closer thanks to research to be published in the International Journal Biomechatronics and Biomedical Robotics.
Spraying reflective particles into the atmosphere to reflect sunlight and then stopping it could exacerbate the problem of climate change, according to new research by atmospheric scientists at the University of Washington.
Enrico Ramirez-Ruiz uses computer simulations to explore the universe's most violent events, so when the first detailed observations of a star being ripped apart by a black hole were reported in 2012 (Gezari et al., Nature), he was eager to compare the data with his simulations. He was also highly skeptical of one of the published conclusions: that the disrupted star was a rare helium star.
Although low temperature fuel cells powered by methanol or hydrogen have been well studied, existing low temperature fuel cell technologies cannot directly use biomass as a fuel because of the lack of an effective catalyst system for polymeric materials.
Tasmanian researchers have revealed ancient conditions that almost ended life on Earth, using a new technique they developed to hunt for mineral deposits.
It was a phrase repeated a thousand times last week: The newly dedicated Ivanpah Solar Electric Generating System will generate enough electricity “to power 140,000 homes,” the stories went. But what exactly does that mean?
An electrode designed like a pomegranate – with silicon nanoparticles clustered like seeds in a tough carbon rind – overcomes several remaining obstacles to using silicon for a new generation of lithium-ion batteries, say its inventors at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory.
From warp drives to hyperspace, science fiction has continuously borrowed from, and sometimes anticipated, the state of the art in scientific progress. This has resulted in the perception that science and science fiction have a causal relationship, one finding direction from and fulfilling the science fantasy laid out before it.
One year ago, on Feb. 15, 2013, the world was witness to the dangers presented by near-Earth Objects (NEOs) when a relatively small asteroid entered Earth's atmosphere, exploding over Chelyabinsk, Russia, and releasing more energy than a large atomic bomb.
Sunspots come in many sizes and shapes and are locations of strong magnetic fields that extend from below the solar surface through the solar atmosphere into the interplanetary medium. They are also the locations of eruptive phenomena, such as flares, that release a tremendous amount of energy and can disrupt technology on Earth.
Growing industrialization threatens the deep ocean's ecosystems, considered key to the health of the planet.
Grasping the concept of climate change and its impact on the environment can be difficult. Establishing common ground and using models, however, can break down barriers and present the concept in an easily understood manner.
