The Atmosphere-Space Interactions Monitor, also known as the Space Storm Hunter, was installed today outside the European space laboratory Columbus. Operators in Canada commanded the International Space Station’s 16-m long robotic arm to move the 314-kg facility from a Dragon spacecraft’s cargo hold to its place of operation on Columbus. Pointing straight down at Earth, […]

Scientists have tracked down an elusive ‘tangled knot’ of DNA Summary: In a world first, researchers have identified a new DNA structure — called the i-motif — inside cells. A twisted ‘knot’ of DNA, the i-motif has never before been directly seen inside living cells. It’s DNA, but not as we know it. In a […]

Neuroscience research is surprisingly brutal – a lot of what we’ve learned about the brain has come from opening up the organ and just poking around.  Definitely not an activity for the squeamish. The best tool for the job? Often, it’s electrodes – a needle-like probe that can be inserted into the brain. Researchers use […]

Last year I described how overhearing one fifth-grade teacher’s laments about teaching her class genetics inspired me to initiate genetics conversations with my own kids—one of whom was a fifth grader at the time. This teacher was describing how her discussions of eye-color inheritance were leading to mass confusion in her classroom. Although it was clear […]

First stable nucleophilic aluminium(I) compound offers new way to make aluminium–carbon bonds The first stable anionic aluminium compound in the +1 oxidation state demonstrates that received wisdom isn’t always right: unlike all other electrophilic aluminium compounds, this unusual molecule is a nucleophile. Researchers from the UK and Finland made the nucleophile by reducing an aluminium(III) complex with […]

Direct sequencing of RNA molecules such as virus genomes could help to unpick role of mysterious chemical modifications in genetic material. The genome of the flu virus has been fully sequenced in its native RNA form for the first time. Previously, all influenza genomes — as well as those of other viruses that store their […]
