The first study to actually ask the women themselves — as well as the largest, most sc…
Listening to music is biological
Music is listened in all known cultures. Similarities between human and animal song have been detected: both contain a message, an intention that reflects innate emotional state that is interpreted correctly even among different species. In fact, se…
Researchers claim advance in quantum cryptography
Researchers have demonstrated a new high-speed quantum cryptography method that uses the properties of light to encrypt information into a form of code that can only be cracked by violating the physical laws of nature. The method promises security even against information security’s greatest foe: the not-yet-invented but still-feared powerful quantum computer, which could break almost any conventional code. The researchers transmitted encrypted data at the rate of 250 megabits per second. Because it uses standard lasers, detectors and other existing optical technology to transmit large bundles of photons, the protocol is more than 1,000 times faster than its main competitor, a technique based on single photons that is difficult and expensive to implement, the researchers say.
