Laser loop couples quantum systems over a distance

For the first time, researchers have succeeded in creating strong coupling between quantum systems over a great distance. They accomplished this with a novel method in which a laser loop connects the systems, enabling nearly ...

All-optical diffractive neural networks process broadband light

Diffractive deep neural network is an optical machine learning framework that blends deep learning with optical diffraction and light-matter interaction to engineer diffractive surfaces that collectively perform optical computation ...

How our tissues manage mechanical stress

When running, breathing and moving, the body is continuously deforming. How do the tissues in the body deal with all these mechanical stresses? Publishing today in Nature Physics, researchers from Wageningen University & ...

Are boys more cliquey than girls?

Children's friendship groups in secondary school remain consistent over time and are often structured around gender, with boys forming the most tight-knit bands, according to new research published in PLOS ONE. The findings ...

After the death of a friend, healing in a human social network

Wounds heal - the cells in a body knit over a cut. When a neuron dies, the brain can rewire itself to make up for the loss. And now, new research suggests, something similar seems to happen within a human social network after ...

Key friendships vital for effective human social networks

Close friendships facilitate the exchange of information and culture, making social networks more effective for cultural transmission, according to new UCL research that used wireless tracking technology to map social interactions ...

Females react differently than males to social isolation

While male and female mice have similar responses to physical stress, research from the Hotchkiss Brain Institute at the University of Calgary, Canada, suggests females, not males, feel stressed when alone.
