Researchers have succeeded in creating a tiny screw-shaped propeller that can move in a gel-like fluid, mimicking the environment inside a living organism. The filament that makes up the propeller, made of silica and nickel, is only 70 nanometers in diameter; the entire propeller is 400 nanometers long.
Researchers have offered a tantalizing new possibility as to what the mysterious molecules in...
Researchers are using medical technology to breathe new life into some antique musical...
A small but growing number of science and math teachers aren't spending the summer at the beach or catching up on books, they're toiling at companies, practicing the principles they teach. As American education focuses on closing the gap between the classroom and employers' needs, programs in North Carolina, California and elsewhere are putting teachers temporarily in the workplace.
A new method of building materials using light could one day enable technologies that are often considered the realm of science fiction, such as invisibility cloaks and cloaking devices.
Scientists say that the newly discovered “28copper15hydride” puts us on a path to better understanding hydrogen, and potentially even how to get it in and out of a fuel system, and is stored in a manner that is stable and safe – overcoming Hindenburg-type risks.
Small-scale advances in fluid physics, materials engineering and nanoscience have brought scientists one step closer to mimicing the way a desert beetle collects and drinks water. Understanding how liquids interact with different materials can lead to more efficient, inexpensive processes and products, and might even lead to airplane wings impervious to ice and self-cleaning windows.
For the first time ever, researchers have created a biodegradable biomaterial that is inherently antioxidant. The material can be used to create elastomers, liquids that turn into gels, or solids for building devices that are more compatible with cells and tissues.
Scientists are looking for ways to turn bamboo into a construction material more akin to wood composites, like plywood. The idea is that a stalk, or culm, can be sliced into smaller pieces, which can then be bonded together to form sturdy blocks—much like conventional wood composites.
A new device, based on a fly's freakishly acute hearing, may find applications in futuristic hearing aids and military technology.
A new material structure generates steam by soaking up the sun. The structure — a layer of graphite flakes and an underlying carbon foam — is a porous, insulating material structure that floats on water.When sunlight hits the structure’s surface, it creates a hotspot in the graphite, drawing water up through the material’s pores, where it evaporates as steam.
Twisting a screwdriver, removing a bottle cap and peeling a banana are just a few simple tasks that are tricky to pull off single-handedly. Now, a new wrist-mounted robot can provide a helping hand — or rather, fingers.
The 1,500 mile Appalachian mountain chain runs along a nearly straight line from Alabama to Newfoundland— except for a curious bend. Now, researchers have found that a dense block of volcanic rock forces the mountains to bend to the east through Pennsylvania, New Jersey and New York.
Ultrafast X-ray laser research has provided scientists with a snapshot of a fundamental molecular phenomenon. The finding sheds new light on microscopic electron motion in molecules.
In an experiment, a new network-management system reduced the average queue length of routers in a Facebook data center by 99.6 percent— virtually doing away with queues.
Physicists are working to bring the theory that parallel universes exist— called the multiverse hypothesis— firmly into the realm of testable science.
In the presence of charged substances, H2O molecules favor associating with elements with a negative electrical charge rather than a positive electric charge. Researchers have published a study on the subject that could provide new insights on the processes of cell formation.
If you’ve ever tried to watch a video on a tablet on a sunny day, you know you have to tilt it at just the right angle to get rid of glare or invest in a special filter. But, scientists are reporting that they’ve developed a novel glass surface that reduces both glare and reflection, which continue to plague even the best mobile displays today.
Scientists have reported the first evidence of a process that can be used to test the mechanism by which the recently discovered Higgs particle imparts mass to other fundamental particles. Rarer than the production of the Higgs itself, this process also provides a new stringent test of the Standard Model of particle physics.
A three-dimensional porous nanostructure would have a balance of strength, toughness and the ability to transfer heat, which could benefit nanoelectronics, gas storage and composite materials that perform multiple functions.
The manipulation of atoms has reached a new level. Physicists have places 20 single atoms on a fully insulated surface at room temperature to form the smallest Swiss cross. This is a big step towards next generation atomic-scale storage devices.
Every machine and device in your life wastes a lot of energy through the loss of heat. But thermoelectric devices can harness that wasted heat, and possibly provide the green tech energy efficiency that's needed for a sustainable future. Now, a new study shows how porous substances can act as thermoelectric materials.
With some no bigger than a hummingbird, drones are the hottest things at this week's Farnborough International Airshow. The drone industry, military and non-military, is growing and could, according to some, see investments of nearly $90 billion over the next 10 years.
Last year, researchers discovered that when water droplets spontaneously jump away from superhydrophobic surfaces during condensation, they can gain electric charge in the process. Now, the same team has demonstrated that this process can generate small amounts of electricity that might be used to power electronic devices.
In the movie “Terminator 2: Judgment Day,” the shape-shifting T-1000 robot morphs into a liquid state to squeeze through tight spaces or to repair itself when harmed. Now, a phase-changing material built from wax and foam, and capable of switching between hard and soft states, could allow even low-cost robots to perform the same feat.
An interdisciplinary research team has developed a novel, tunable nanoantenna that paves the way for new kinds of plasmonic-based optomechanical systems whereby plasmonic field enhancement can actuate mechanical motion.
A grad student has developed a system for locating a person via his or her mobile phone with a drone. This device could be used to find victims in natural disasters.
Scientists have demonstrated for the first time a photonic router– a quantum device based on a single atom that enables routing of single photons by single photons. This achievement is another step toward overcoming the difficulties in building quantum computers.
