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.

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.

Carbon dioxide study adds to picture of global carbon cycle
(Phys.org) —One of the most widely known compounds on Earth is carbon dioxide, or CO2. We learn as children that CO2 is a key component of photosynthesis, the process by which plants, algae, and bacteria c ...
