General principles to explain DNA brick self-assembly
Channeling valleytronics in graphene: Researchers discover 1-D conducting channels in bilayer graphene
To the list of potential applications of graphene – a two-dimensional semiconductor of pure carbon that is stronger and much faster than silicon – we can now add valleytronics, the coding of data in the ...
Study shows even newly hatched chicks have a left to right number space map (w/ Video)
Calculating encryption schemes' theoretical security guarantees eases comparison, improvement
Most modern cryptographic schemes rely on computational complexity for their security. In principle, they can be cracked, but that would take a prohibitively long time, even with enormous computational resources.
The ABC's of animal speech: Not so random after all
The calls of many animals, from whales to wolves, might contain more language-like structure than previously thought, according to study that raises new questions about the evolutionary origins of human language.
Phone snooping via gyroscope to be detailed at Usenix
Autonomous robots: A self-organizing thousand-robot swarm (w/ Video)
The first thousand-robot flash mob has assembled at Harvard University.
Experiments show disproportionately large number of big boulders on asteroids likely due to Brazil-nut effect
When it comes to numbers, culture counts
American children learn the meanings of number words gradually: First they understand "one," then they add "two, "three," and "four," in sequence. At that point, however, a dramatic shift in understanding ...
Opening a wide window on the nano-world of surface catalysis
(Phys.org) —Surface catalysts are notoriously difficult to study mechanistically, but scientists at the University of South Carolina and Rice University have shown how to get real-time reaction information ...
Researchers crack unassailable encryption algorithm in two hours
(Phys.org) —A protocol based on "discrete logarithms", deemed as one of the candidates for the Internet's future security systems, was decrypted by EPFL researchers. Allegedly tamper-proof, it could only ...
Mathematicians trace source of Rogers-Ramanujan identities, find algebraic gold
Mathematicians have found a framework for the celebrated Rogers-Ramanujan identities and their arithmetic properties, solving another long-standing mystery stemming from the work of Indian math genius Srinivasa Ramanujan.
