The Dangerous Insufficiency of ‘No Means No’
There is an approach to the giving of constructive criticism that is sometimes referred to, in the corporate world and beyond, as a compliment sandwich .

Sunscreen for dancing molecules
Since life is mostly based on water, our molecules are moving, vibrating and somersaulting in a liquid environment. But electron microscopy—a technique to study a static version of this nanoworld—has been almost impossible to use to see moving molecules, because the incident electron beam damages the samples. Scientists at the Center for Soft and Living Matter, within the Institute for Basic Scien

The growing gap between physical and social technologies
The word "technology," from the Greek techne, usually evokes physical technologies like artificial intelligence, swarm robots, and the like. But there's an older meaning. By Jacob Bigelow's 1829 definition, technology can describe a process that benefits society. In that sense, social institutions, like governments and healthcare systems, can be seen, and studied, as technologies.

Questioning conventional understanding of antifreeze proteins
Scientists have discovered that an ice-binding protein (fcIBP) from the sea ice microalga does not fit in the conventional classification of ice-binding proteins, suggesting unknown mechanisms behind its antifreeze property. This finding could lead to a broader application of the antifreeze protein in food and medical industries.
