A complex logic circuit made from bacterial genes

(Phys.org)—By force of habit we tend to assume computers are made of silicon, but there is actually no necessary connection between the machine and the material. All that an engineer needs to do to make a computer is to ...

Singing sexy back: How sparrows adapted to COVID-19 shutdown

As the streets of San Francisco emptied out in the first months of the pandemic, the city's male birds began singing more softly and improving their vocal range, making them "sexier" to females, according to a new study published ...

Quantum Hall-based superconducting interference device

In a recent report published on Science Advances, Andrew Seredinski and co-workers presented a graphene-based Josephson junction with dedicated side gates fabricated from the same sheet of graphene as the junction itself. ...

On-chip quantum buffer realized

Nippon Telegraph and Telephone Corp. has realized a quantum buffer integrated on an optical waveguide. The buffer is based on the "slow light effect", where the propagation speed of a pulsed light in a special optical waveguide ...

Scientists create working artificial nerve networks

Scientists have already hooked brains directly to computers by means of metal electrodes, in the hope of both measuring what goes on inside the brain and eventually healing conditions such as blindness or epilepsy. In the ...

'Chaogates' hold promise for the semiconductor industry

In a move that holds great significance for the semiconductor industry, a team of researchers has created an alternative to conventional logic gates, demonstrated them in silicon, and dubbed them "chaogates." The researchers ...
