New chip paves the way for optical quantum technology in laptops and smartphones

In quantum physics, entangled photons are the cornerstone of much cutting-edge technology research, including quantum communications, computing, and encryption. Now an international team of researchers claims to have incorporated a range of quantum technologies on a single integrated chip that is compatible with existing fiber and semiconductor applications, and may soon provide the means to build quantum circuits directly into laptops and cell phones.Read More

Shrimp communications shed light on new optical material

The study of an unusual communication method used by mantis shrimp has provided an unexpected insight that could lead to a new take on optical devices used in many consumer products, from sunglasses to cameras. The study, which was led by researchers at the University of Bristol in the United Kingdom, successfully revealed the mechanism by which the little crustaceans are able to manipulate the polarization of light.Read More

Hyperlens significantly boosts image resolution of microscopic objects

Using visible light magnified through a compound series of lenses to image small objects, standard optical microscopes have been with us for many centuries. Whilst continually being improved, the result of these many advances of optics and image-capturing techniques means that many high-end optical microscopes have now reached the limit of magnification possible as they push the resolution properties of light itself. In an attempt to resolve this issue, scientists at the University of Buffalo (UB) have created a prototype visible light "hyperlens" that may help image objects once only clearly viewable through electron microscopes.Read More

New invention expands Wi-Fi bandwidth tenfold

The vast range of Wi-Fi-enabled devices available today means that anyone could have several personal electronic devices all trying to connect to a network simultaneously. Multiply this by many hundreds of people in a busy public place with Wi-Fi connectivity and this often means that available bandwidth is greatly reduced. To help address this problem, researchers at Oregon State University claim to have invented a new system called WiFO that incorporates infrared LEDs to boost the available Wi-Fi bandwidth by as much as ten times.Read More

25 years in orbit: A celebration of the Hubble Space Telescope

April 24 will mark a significant milestone in the life of one of mankind's greatest scientific instruments – the 25-year anniversary of the launch of the Hubble Space Telescope. This bus-sized piece of scientific equipment has become a household name, thanks to the incredible scientific insights and iconic images it has returned over the course of a quarter-century in low-Earth orbit. Join us as we celebrate the history and achievements of NASA's flagship space telescope. Read More

Artificial "skin" changes color in response to minute force

A thin and flexible chameleon-like material developed by engineers at the University of California, Berkeley changes color when stretched or bent even tiny amounts. With potential applications in camouflage, structural fatigue sensors, display technologies, and more, the material's color changes reliably as it gets flexed thanks to rows of ridges that are precisely etched onto a silicon film one thousand times thinner than a human hair.Read More
