Modern hand dryers are much worse than paper towels when it comes to spreading germs, according to new research. A study found that airborne germ counts were 27 times higher around jet air dryers in comparison with the air around paper towel dispensers.

Air tour operators at the Grand Canyon would be able to take more visitors over the most popular flight routes under a proposed incentive to make aircraft quieter. The incentive would apply to the Dragon and Zuni Point corridors, which provide views of the widest and deepest parts of the canyon to the eastern edge.
Physicists have engineered a spiral laser beam and used it to create a whirlpool of hybrid light-matter particles called polaritons. The ability to control polariton flows in this way could aid the development of completely novel technology to link conventional electronics with new laser- and fiber-based technologies.
Researchers from the Univ. of Cambridge have developed artificial muscles that can learn and recall specific movements, the first time that motion control and memory have been combined in a synthetic material. The "muscles," made from smooth plastic, could eventually be used in a wide range of applications where mimicking the movement of natural muscle would be an advantage.
Since the 1850s scientists have known that crystalline materials are organized into fourteen different basic lattice structures. However, a team of researchers is reporting that it has discovered an entirely new form of crystalline order that simultaneously exhibits both crystal and polycrystalline properties, which they describe as "interlaced crystals."
The most accurate laboratory measurements yet made of magnetic fields trapped in grains within a primitive meteorite are providing important clues to how the early solar system evolved. The measurements point to shock waves traveling through the cloud of dusty gas around the newborn Sun as a major factor in solar system formation.
A new study suggests how scientists might deliberately engineer superconductors that work at higher temperatures. These findings open a new chapter in the 30-year quest to develop superconductors that operate at room temperature, which could revolutionize society by making virtually everything that runs on electricity much more efficient.
The international standard for time is set by atomic clocks— room-sized apparatuses that keep time by measuring the natural vibration of atoms in a vacuum. Now, researchers have come up with a new approach to atomic timekeeping that may enable more stable and accurate portable atomic clocks, potentially the size of a Rubik’s cube.
Researchers have chemically engineered a new, electrically conductive nanomaterial that is flexible enough to fold, but strong enough to support many times its own weight. They believe it can be used to improve electrical energy storage, water filtration and radiofrequency shielding in technology from portable electronics to coaxial cables.
A group of researchers from Austria have sent twisted beams of light across the rooftops of Vienna. It is the first time that twisted light has been transmitted over a large distance outdoors, and could enable researchers to take advantage of the significant data-carrying capacity of light in both classical and quantum communications.
Tiny, thin microtubes could provide a scaffold for neuron cultures to grow so that researchers can study neural networks, their growth and repair, yielding insights into treatment for degenerative neurological conditions or restoring nerve connections after injury.
Researcher teams have independently developed methods of making super-slippery surfaces by creating stable mixtures of liquids and solids. The developments promise consumer applications such as toothpaste tubes that release the last portions of their contents without the need to roll them up and bottles that deliver ketchup as soon as they are tilted, eliminating the need to squeeze or shake them.
Researchers have invented a single tiny structure that includes all the components of a battery that they say could bring about the ultimate miniaturization of energy storage components. The structure is called a nanopore: a tiny hole in a ceramic sheet that holds electrolyte to carry the electrical charge between nanotube electrodes at either end.
Last year, CERN announced the finding of a new elementary particle, the Higgs particle. But maybe it wasn't the Higgs particle, maybe it just looks like it. And maybe it is not alone.
A new study, which teamed cutting-edge engineering techniques with paleontology, has found that take-off capacity may have determined body size limits in extinct flying reptiles. Findings suggest that a pterodactyl with a wingspan of 12 meter or more would simply not be able to get off the ground.
Scientists have shown that a promising technique for accelerating electrons on waves of plasma is efficient enough to power a new generation of shorter, more economical accelerators. This could greatly expand their use in areas such as medicine, national security, industry and high-energy physics research.
Since 1999, the conjecture by Asher Peres— who invented quantum teleportation— has piqued the interest of many scientists in the field. According to his hypothesis, the weakest form of quantum entanglement can never result in the strongest manifestation of the phenomenon. Now, a team of researchers has proven this conjecture to be false.
A synthetic fish is helping existing hydroelectric dams and new, smaller hydro facilities become more fish-friendly. The latest version of the Sensor Fish— a small tubular device filled with sensors that analyze the physical stresses fish experience— measures more forces, costs about 80 percent less and can be used in more hydro structures than its predecessor.
The physics community has spent three decades searching for and finding no evidence that dark matter is made of tiny exotic particles. Now, theoretical physicists suggest researchers consider looking for candidates more in the ordinary realm and more massive.
As the U.S. nuclear deterrent ages, one essential factor in making sure that the weapons will continue to perform as designed is understanding the fundamental properties of the high explosives that are part of a nuclear weapons system. A new video shows how researchers use scientific guns to induce shock waves into explosive materials to study their performance and properties.
The renowned lab that confirmed the existence of the elusive "God particle" has selected an Italian physicist who played a key role in that research to be its new director general. CERN has announced that Fabiola Gianotti will become the first female director general when she takes over in 2016.
Every year, nearly 4,000 children go to emergency rooms after swallowing button batteries. Ingesting these batteries has severe consequences, including burns that permanently damage the esophagus, tears in the digestive tract and, in some cases, even death. To help prevent such injuries, researchers have devised a new way to coat batteries with a special material that prevents them from conducting electricity after being swallowed.
The field of quantum communication, the science of transmitting quantum states from one place to another, grabbed global attention in recent years after the discovery of quantum cryptography, which is described as a way of creating "unbreakable" messages. Now, China’s leading Chinese quantum physicist says the country will build a global quantum communication network by 2030.
Two photons in free space do not interact. Light waves can pass through one other without having any influence on each other. For many applications in quantum technology, however, interaction between photons is crucial. Now, scientists have succeeded in establishing a strong interaction between two single photons. This opens up new possibilities for quantum optics.
A disappearing act was the last thing a physicist expected to see in his ultracold atomic experiments, but that is what he and his students produced by colliding pairs of Bose Einstein condensates that were prepared in special states called solitons.
Researchers have found an unusual mass of rock deep in the active fault line beneath Chile that influenced the rupture size of a massive earthquake that struck the region in 2010. The geological structure is unusually dense and large for this depth in the Earth's crust. The body was revealed using 3-D seismic images of Earth's interior based on the monitoring of vibrations on the Pacific seafloor.
