Non-Gaussian curves are necessary for studying quantum systems, but they can also be composed of mixtures of regular Gaussian curves, producing difficulties for physicists studying quantum entanglement. In new research published in EPJ D, researchers at Huaihua University suggest an updated set of equations which allows physicists to easily check whether or not a non-Gaussian state is genuinely quantum.
In some specialised oscillators, two driving forces with significantly different frequencies can work together to make the whole system resonate.
Babies born into bilingual homes change the focus of their attention more quickly and more frequently than babies in homes where only one language is spoken, according to new research published in the journal Royal Society Open Science.
Mantis shrimps are able to fire off high power punches in water at the speed of a bullet, but it now turns out that they are nowhere near as fast in air, only striking with blows that are a tenth of the power at just 18km/h. The crustaceans probably pull their air punches to protect themselves from damage in the thinner medium, which does not dissipate energy was well as water.
Cameras shooting up to 25,000 frames a second have been used to capture the moment two droplets of liquid come together and mix -- and it is opening up research into new applications for 3D printing.
Some species of deaf moths can absorb as much as 85 per cent of the incoming sound energy from predatory bats -- who use echolocation to detect them. The findings, published in Royal Society Interface today, reveal the moths, who are unable to hear the ultrasonic calls of bats, have evolved this clever defensive strategy to help it survive.
A new infection test, made up of sheets of paper patterned by lasers, has been developed by University of Southampton researchers to allow diagnosis at the point of care -- helping doctors give patients the right treatment, faster.
Young burglars are driven by a desire for excitement when they initially commit crime, new research from the University of Portsmouth has found.
Oldest reconstructed bacterial genomes link agriculture and herding with emergence of new disease.
Professors Eyal Ert and Aliza Fleischer analyzed 320 Airbnb listings in Stockholm, Sweden and gleaned two main criteria that determine 'visual trustworthiness': One, is the host's characteristics (e.g., gender, facial expression) and the second is the quality of the image itself (e.g., blurry or clear).
