Knowing where harmful airborne pollutants are and in what concentrations would be an invaluable capability, and one that a team of Rice University scientists is making great headway on with their autonomous gas-sensing drones.

Scientists from Rice University, Texas, have identified a parasitic plant that preys on both trees and the wasps that use them as a nursery for their young. The team hope that their discovery could one day aid scientists in controlling agricultural pests, and maybe even help target cancer cells.

To make concrete more environmentally friendly, the industry has been adding by-products from coal-fired power plants, but doing so had its own problems. Now, Rice researchers have developed a new composite binder that requires no cement, and reduce waste from power plants at the same time.

British electronic music icon Massive Attack is marking the 20th anniversary of the release of its most successful album – Mezzanine – by having it stored in DNA molecules. Digital audio will be translated into genetic code and stored in DNA strands housed in tiny glass beads.

Researchers have developed a new “mat” that can adsorb and destroy pollutants from water. It's made up of titanium dioxide nanoparticles embedded into polymer fibers, which destroys contaminants through UV light. The team says the design is faster, safer and more energy efficient than other systems.

Graphene hogs all the headlines about two-dimensional materials, but it might just be the beginning. Researchers have now isolated a 2D form of the soft metal gallium, dubbed "gallenene," which could make for efficient, thin metal contacts in electronic devices.

The cure for cancer might have been inside us all along – our immune system. The trick of immunotherapy is to boost it to find and destroy those rogue cells. A new hydrogel has been developed that can be injected directly to the site of a tumor, slowly releasing immunotherapy drugs for longer.

As tiny as they are, there's a relatively large amount of empty space inside an atom. Now, scientists from Austria and the US have filled in some of those gaps, creating a new state of matter in the form of "giant atoms" filled with other atoms.

Now you can have your wonder material and eat it, too. The lab of James Tour at Rice University has demonstrated a way to etch graphene onto food like bread and potatoes, as well as materials like cardboard and cloth, where it could then act as an RFID tag.

Aluminum is nice and light, but that comes at the cost of strength. By introducing faults into the metal’s crystalline structure, researchers at Purdue University have now developed new aluminum alloys that are about as strong as stainless steel, and they could make for corrosion-resistant coatings.
