Image: Pinhole propulsion for satellites

A palm-sized propulsion option for future space missions: Each one of these seven emitter arrays etched onto this silicon wafer using micro- and nano-technology possesses more than 500 pinhole-sized emitters that spray out ...

Two teams use neutral atoms to create quantum circuits

Two teams of researchers working independently have shown the viability of using neutral atoms to create quantum circuits—both have published outlines of their work in the journal Nature. One of the groups, with members ...

In situ extraction and detection of DNA using nanopores

Being able to detect DNA from a single cell is important for the detection of diseases and genetic disorders. Measuring single DNA molecules has been possible for some time; however, directly detecting samples at the point ...

Bees use shark 'supersense' to help find food

Flying insects such as bees and moths have secret senses that allow them to 'feel' nearby flowers and navigate over long distances, according to new research.

New quantum switch turns metals into insulators

Most modern electronic devices rely on tiny, finely-tuned electrical currents to process and store information. These currents dictate how fast our computers run, how regularly our pacemakers tick and how securely our money ...

Flowers use physics to attract pollinators

A new review indicates that flowers may be able to manipulate the laws of physics, by playing with light, using mechanical tricks, and harnessing electrostatic forces to attract pollinators.

Diffraction-controlled laser-driven proton acceleration

A targeted way to manipulate beams of protons accelerated using ultrashort and ultraintense laser pulses has been demonstrated by a team of researchers led at the University of Strathclyde.
