In the same way as we now connect computers in networks through optical signals, it could also be possible to connect future quantum computers in a quantum Internet. The optical signals would then consist of individual light particles or photons. One prerequisite for a working quantum Internet is control of the shape of these photons.
A species of small fish uses a homemade coral-scented cologne to hide from predators, a new study has shown, providing the first evidence of chemical camouflage from diet in fish. Filefish evade predators by feeding on their home corals and emitting an odor that makes them invisible to the noses of predators, the study found.
A project by students from The Univ. of Western Australia and Mars One astronaut candidate Josh Richards has reached the finals of an international competition to land vital experiments on the Red Planet. The Helena Payload project, which aims to generate the first breathable air on Mars, is one of 10 finalists in the Mars One University Competition and is the only successful entry from the southern hemisphere.
Where did the songbird get its song? What branch of the bird family tree is closer to the flamingo: the heron or the sparrow? These questions seem simple, but are actually difficult for geneticists to answer. A new, sophisticated statistical technique developed by researchers can help researchers construct more accurate species trees detailing the lineage of genes and the relationships between species.
An ancient meteorite and high-energy x-rays have helped scientists conclude a half century of effort to find, identify and characterize a mineral that makes up 38% of the Earth. And in doing so, a team of scientists clarified the definition of the Earth's most abundant mineral, a high-density form of magnesium iron silicate, now called Bridgmanite, and defined estimated constraint ranges for its formation.
For decades, the mantra of electronics has been smaller, faster, cheaper. Today, Stanford Univ. engineers add a fourth word: taller. A Stanford team revealed how to build high-rise chips that could leapfrog the performance of the single-story logic and memory chips on today's circuit cards.
A way to use weak molecular bonding interactions to create well-ordered and stable metal–organic monolayers with optoelectronic properties has been found by researchers from the RIKEN Surface and Interface Science Laboratory.
ESA is developing technologies for advanced human–machine interaction to transfer the human sense of touch to space.
Earlier this month, the NTSB released its Aircraft Incident Report on a fire aboard a Japan Airlines Boeing 787, concluding that the fire was probably caused by an internal short circuit within a cell of the lithium-ion battery.
Stanford University's Precourt Institute for Energy, Precourt Energy Efficiency Center and TomKat Center for Sustainable Energy have awarded eight seed grants totaling about $1.5 million for promising new research in clean technology and energy efficiency.
A rare weather phenomenon at the Grand Canyon had visitors looking out on a sea of thick clouds just below the rim. The total cloud inversion is expected to hang inside the canyon throughout Thursday.
Researchers have begun to describe theoretical limits on the degree of imprecision that communicating computers can tolerate, with very real implications for the design of communication protocols.
The first ever landing of a man-made probe onto a comet has been named Physics World Breakthrough of the Year for 2014. From a shortlist of 10 highly commended breakthroughs, the historic achievement by scientists working on the Rosetta mission was singled out by the Physics World editorial team for its significance and fundamental importance to space science.
RoboSimian was created for the DARPA Robotics Challenge, a competition consisting of several disaster-related tasks for robots to perform. Using extra limbs from RoboSimian, researchers constructed Surrogate. Over the past six months, they have been testing both robots to see which one should compete in the finals.
Growing resistance to malaria drugs in Southeast Asia is caused by a single mutated gene inside the disease-causing Plasmodium falciparum parasite. This finding provides public health officials around the world with a way to look for pockets of emerging resistance and potentially eliminate them before they spread.
