Graphene, a sheet of carbon atoms a few atoms thick, is seen as a miracle material: it’s 200 times tougher than steel per unit of weight, is an excellent electrical conductor, and weighs only a fifth as much as aluminum. 

Scientists have made an optical disc from a new material called "dye-doped photoresist with aggregation-induced emission luminogens" (AIE-DDPR) that can store a “petabit” of data, equivalent to the capacity of more than 5,000 DVDs.

Everything that lives is made of DNA. DNA is made up of the sugar deoxyribose that forms its helical backbone and just four nucleotides—adenine, cytosine, guanine, and thymine.

Hydrogen is making headlines as a potentially limitless clean fuel that holds more energy in a given space than lithium-ion batteries. (See “A Gold Rush for Gold Hydrogen” 5 Mar 2024.) However, as hydrogen’s benefits draw more interest, so does a key problem: the gas is hard to store.

For the first time, researchers have 3D-printed layered, living skin onto wounded areas of a living creature, preventing scarring, possible infection, and other dangers that can accompany skin grafts.

Electronic trash is laced with rare minerals and even gold—but recovering that gold from discarded computers’ circuitry has been too complex and expensive to make it worthwhile.

Azolla is a common plant that grows on water like a thick mat and can double its biomass in two days under the right conditions.

As much as 500 trillion tons of hydrogen lies beneath the Earth’s surface, a gas that could fuel everything from vehicles to electric generators.
