Read More‘Fruitcake’ structure observed in organic polymers
Researchers have analyzed the properties of an organic polymer with potential applications in flexible electronics and uncovered variations in hardness at the nanoscale, the first time such a fine structure has been observed in this type of material.
Read MoreBreakthrough artificial photosynthesis comes closer
Imagine we could do what green plants can do: photosynthesis. Then we could satisfy our enormous energy needs with deep-green hydrogen and climate-neutral biodiesel. Scientists have been working on this for decades. Chemist Chengyu Liu will receive his doctorate on 8 June for yet another step that brings artificial photosynthesis closer. He expects it to […]

A new technology is using particles of gold to make colors. With further work, the method developed at Aalto University could herald a new display technology.
Read MoreSuperionic compound with the highest hydrogen content successfully predicted and explored
In collaboration with scientists from Jilin University in China, a group of Skoltech researchers led by Professor Artem R. Oganov discovered a unique compound—strontium hydride SrH22. It has the highest hydrogen content known so far and is stable at pressures of 80–140 gigapascals (about a million atmospheres). The compound obtained has mobile hydrogens, capable of […]

Subtle Aptamer Binding
Aptamers are interesting beasts. In general, they’re nothing more than oligonucleotides (DNA or RNA) that have been screened/selected to recognize some particular target. Because the machinery of molecular biology lets you generate truly insane numbers of different oligos, you can screen vast landscapes for binding partners and amplify them once one turns up, even if […]
Read MoreThe world’s fastest supercomputer just broke the exascale barrier
The first exascale computer has officially arrived. The world’s fastest supercomputer performed more than a quintillion calculations per second, entering the realm of exascale computing. That’s according to a ranking of the world’s speediest supercomputers called the TOP500, announced on May 30. The computer, known as Frontier, is the first exascale computer to be included […]
Read MoreTrained dogs sniff out COVID-19 as well as lab tests do
Dogs are as reliable as laboratory tests for detecting COVID-19 cases, and may be even better than PCR tests for identifying infected people who don’t have symptoms. A bonus: The canines are cuter and less invasive than a swab up the nose. In a study involving sweat samples from 335 people, trained dogs sniffed out […]
