String theory is the leading candidate for a “theory of everything” — and Subir Sachdev is taking the “everything” part literally. In a conversation with Quanta Magazine, Sachdev explains how he’s taking inspiration from the mathematics of string theory to learn more about the behavior of high-temperature superconductors.
A new type of glass to reducing electric bills.
A revolutionary new type of smart window developed by the University College London (UCL) and the Engineering and Physical Sciences Research Council (EPSRC) could cut window-cleaning costs in tall buildings while reducing heating bills and boosting worker productivity. Partially inspired by the reflective properties of moth eyes, this smart window is said to be self-cleaning, energy saving, and anti-glare.
When rain hits the outside of the smart window it forms spherical droplets that roll over the surface and pick up dirt, dust and other contaminants, then carries them away. This can either eliminate or reduce the need for manual cleaning.

China’s improved glass for space.
Chinese scientists developed a method to create a transparent, glass-based material with the power and lifespan to absorb ultraviolet rays. The metal oxide-based special glass is expected to not break down under prolonged UV radiation exposure. (Photo : John T. Clarke (University of Michigan), ESA, NASA | Wikimedia Commons)

More VR Theme Parks and attractions opening this year. We have the Void opening this summer in Pleasant Grove, UT; a new VR roller coaster in UK’s Alton Towers that opens in April; there is real opportunity for entrepreneurs in the VR space to launch their own portable VR amusement/ entertainment centers for corporate events, parties, etc.
Virtual reality and theme parks may not seem like an obvious match, but these planned attractions may change your mind. Starting this spring we’ll start to see rides that take advantage of VR to offer new and exciting experiences.

Change NextGen Product Landscape
The electromagnetic properties of graphene and boron nitride hybrids has been defined by new research. The results provide a roadmap for new nano-engineered applications.” id=” metasummary.
Retaining information even when loss of power.
Small voltage can flip thin film between two crystal states — one metallic, one semiconducting — new research indicates. The research involves a thin-film material called a strontium cobaltite, or SrCoOx.”
Graphene’s properties make it a tantalizing target for semiconductor research. Now a team from Princeton has showed that flakes of graphene can work as fast, accurate optical capacitors for laser transistors in neuromorphic circuits.
This new material is remarkably soft, and it could revolutionize robotics and prosthetics.
Researchers from the Monash University have discovered a new sponge-like material called graphene elastomer. This revolutionary material is expected to be used for robots designed to help take care of elderly people.
The graphene-based elastomer is exteremely sensitive to pressure and vibrations. Also called G-elastomer, the material has the ability to bounce back despite the pressure given to it. It is described to be very soft and elastic compared to other substances such as rubber or foam.
As much as some people fear getting dental fillings or root canals, what many of them are really afraid of is the needle that delivers the anesthetic into the mouth tissue. Even though the skin in the “jabbing area” is usually pretreated with a topical anesthetic, it can still hurt. Before long, however, a shot of electricity could make that topical treatment deep-acting enough that the needle isn’t even needed.
In a recent study, scientists from the University of Sao Paulo in Brazil combined two commonly-used anesthetic drugs – prilocaine hydrochloride and lidocaine hydrochloride – with a polymer to form a hydrogel. The polymer was included to make it sticky, so that it could be applied to the lining of a pig’s mouth.
Using a process known as iontophoresis, a mild and painless electrical current was then passed through the hydrogel. As a result, there was a 12-fold increase in how well the prilocaine hydrochloride permeated through the tissue. The anesthetic effect was claimed to be not only fast-acting, but also long-lasting.
