1000 år gammel legetøjsbåd i Norge

The toy boat that sailed the seas of time
A thousand years ago, for reasons we will never know, the residents of a tiny farmstead on the coast of central Norway filled an old well with dirt. Maybe the water dried up, or maybe it became foul. But when archaeologists found the old well and dug it up in the summer of 2016, they discovered an unexpected surprise: a carefully carved toy, a wooden boat with a raised prow like a proud Viking shi

Interactive health apps may inspire healthy behaviors, but watch the tone
Just like real doctors and nurses, online health tools with good — but controlled — communication skills can promote healthier lifestyles, according to researchers. However, if their tone is conversational, these tools may lull users into a false sense of comfort, they add. In a study, people who experienced a back-and-forth interaction with an online health risk assessment website were more lik

Diamond’s 2-billion-year growth charts tectonic shift in early Earth’s carbon cycle
A study of tiny mineral 'inclusions' within diamonds from Botswana has shown that diamond crystals can take billions of years to grow.

Analysis of the inclusions also suggests

DNA er elektrisk – det letter reparationer

Electrons use DNA like a wire for signaling DNA replication
In the early 1990s, Jacqueline Barton, the John G. Kirkwood and Arthur A. Noyes Professor of Chemistry at Caltech, discovered an unexpected property of DNA—that it can act like an electrical wire to transfer electrons quickly across long distances. Later, she and her colleagues showed that cells take advantage of this trait to help locate and repair potentially harmful mutations to DNA.

Many laboratories, consortia and projects are devoted to get a global view of the functional regions of the genome and to know in which cell types genes are active.

Saturn's rings viewed in the mid-infrared show bright cassini division
A team of researchers has succeeded in measuring the brightnesses and temperatures of Saturn's rings using the mid-infrared images taken by the Subaru Telescope in 2008. The images are the highest resolution ground-based views ever made. They reveal that, at that time, the Cassini Division and the C ring were brighter than the other rings in the mid-infrared light and that the brightness contrast

Controlling the stiffness of a material at the nanoscale
Using a needle far thinner than a human hair, scientists revealed how to control mechanical stiffness in a promising material. The team applied an electric field with a nano-sized needle to cause a reversible change in the arrangement of the atoms in the material. This change is a phase transition. The team reconfigured the atomic force microscope they used to measure the resulting change in the m
