High-fidelity recording of molecular geometry with DNA 'nanoscopy'

Researchers at Harvard's Wyss Institute create a DNA nanotechnology-based method, called Auto-cycling Proximity Recording (APR), that allows for repeated, non-destructive recording of molecular pairings. This enables the creation of detailed views of molecular structures and observation of different structural states.

Organic consumers mean business

Research from Aarhus University found that once consumers start buying organic products, they are likely to continue and increase the number of organic products on their shopping list. This is due to a phenomenon known as a behavioural spillover effect, where purchasing organic products strengthens consumers' moral identity.

People are reluctant to use public defibrillators to treat cardiac arrests

A study by the University of Warwick found that public access defibrillators are often not used because people don't know how to use them or where to find them. The study suggests that investment in more AEDs is crucial, but it's equally important to maximize existing defibrillator use.

Role of microorganisms in the formation of unique iron ore caves

Researchers at University of Akron investigate high microbial communities in BIF caves, theorizing microbes use iron to respire and cause rust-like oxides to become soluble. This process could be responsible for voids forming within the cave walls, eventually leading to new cave formation.
