Fear not the deadlines

New research suggests the stress levels of knowledge workers, such as researchers or journalists, stays the same with or without deadlines.

It’s not as difficult as you think to shout upwind

Why does it feel so difficult to shout upwind? The sensation is common enough to have found its way into an idiom about not being understood. Researchers wanted a scientific explanation for the phenomenon — and there wasn’t been one. They have now sho…

A more precise model of the Earth’s ionosphere

The ionosphere — the region of geospace spanning from 60 to 1000 kilometers above the Earth — impairs the propagation of radio signals from global navigation satellite systems (GNSS) with its electrically charged particles. This is a problem for the …

Better superconductors with palladium

A new age of superconductors may be about to beginn: In the 1980s, many superconducting materials (called cuprates) were based on copper. Then, nickelates were discovered — a new kind of superconducting materials based on nickel. But now, scientists f…

Significant variation in anatomy of human guts

New research finds there is significant variation in the anatomy of the human digestive system, with pronounced differences possible between healthy individuals. The finding has implications for understanding the role that the digestive tract’s anatomy…
