Imagine printing out molecules that can respond to their surroundings. Chemists teamed up with engineers who are using 3-D printers to create 3-D printed objects with new capabilities. Scientists created a bone-shaped plastic tab that turns purple under stretching, offering an easy way to record the force on an object.

Biomass conversion to electricity combined with technologies for capturing and storing carbon, which should become viable within 35 years, could result in a carbon-negative power grid in the western US by 2050. That prediction comes from an analysis of various fuel scenarios. Bioenergy with carbon capture and sequestration may be a better use of plant feedstocks than making biofuels.

Researchers have demonstrated a new way to activate genes with light, allowing precisely controlled and targeted genetic studies and applications. The method might be used to activate genes in a specific location or pattern, allowing more precise study of gene function, or to create complex systems for growing tissue or new therapies.

Researchers have created a broad color palette of electrochromic polymers, materials that can be used for sunglasses, window tinting and other applications that rely on electrical current to produce color changes. The materials could allow sunglasses that change from clear to colored in seconds, at the push of a button.

Researchers have developed a novel 3-D vaccine that could provide a more effective way to harness the immune system to fight cancer as well as infectious diseases. The vaccine spontaneously assembles into a scaffold once injected under the skin and is capable of recruiting, housing, and manipulating immune cells to generate a powerful immune response. The vaccine was recently found to be effective in delaying tumor growth in mice.

Connecting different kinds of devices, not just computers and communications devices, to the Internet could lead to new ways of working with a wide range of machinery, sensors, domestic and other appliances. Researchers suggest that we are on the verge of a another technological revolution but practicalities and legal obstacles may stymie the development of the so-called Internet of Things if they are not addressed quickly.

In the quantum world, the future predicts the past. Playing a guessing game with a superconducting circuit called a qubit, a physicist has discovered a way to narrow the odds of correctly guessing the state of a two-state system. By combining information about the qubit's evolution after a target time with information about its evolution up to that time, the lab was able to narrow the odds from 50-50 to 90-10.

Researchers have designed and developed hybrid gold-silica nanoparticles, which are turning out to be genuine therapeutic “Swiss Army knives”. Tested in mice and on cultured human cells, they make it possible to combine two forms of tumor treatment and three imaging techniques. They notably have a greater drug loading and delivery capacity than carriers currently on the market, which opens interesting perspectives for cancer research.
