Liquid crystals are all around us, from cell phone screens and video game consoles to car dashboards and medical devices. Run an electric current through liquid crystal displays (LCDs) and they generate colours, thanks to the unique properties of these fluids: rearrange their shape, and they reflect different wavelengths of light. As the lab of […]
A strange seismological signal that persisted for nine days in 2023 explained Melting glacial ice set off a cascade of events in Greenland in September, ending in tsunami waves bouncing back and forth in a fjord for nine days, with waves reaching heights of 110 meters. The research describes the ice melt triggering a landslide […]
Chromatin is a complex of DNA and histone, a protein, in the nucleus of a cell. One of the main functions of chromatin is to help DNA packing. Cellular phenotypic heterogeneity is a key determinant of many biological functions; yet, it is still not clear whether it stems from the modifications of the chromatin structure […]
What would happen if humans dried out the Mediterranean sea, turning it into a giant salt lake? Would its wildlife survive, and if so, how long would it take to recover? These may seem like wildly theoretical questions, but not for Herman Sörgel, a Bavarian architect who dedicated much of his life to this exact […]
Author: Leah Burrows, Harvard John A. Paulson School of Engineering and Applied Sciences The earliest blacksmiths in the Bronze and Iron Ages figured out that when they deformed metal through bending or hammering, it became stronger. This process, known as work or strain hardening, is still used widely in metallurgy and manufacturing today to increase […]

New dinosaur species’ traits hint at ceratopsian migration Scientists have identified a previously unknown dinosaur species, Sasayamagnomus saegusai, that weighed about 10 kilograms and reached about 0.8 meters in length, based on fossil remains from southwestern Japan. The primitive member of the herbivorous ceratopsian group lacks the frills and horns of triceratops and other later […]

Molecular spintronics is an emerging field that combines ferromagnetic materials with organic or metal–organic semiconductors. It benefits from the unique and exceptional properties of organic molecules, which go beyond inorganic ones. The strong response of many organic molecules to electrical, optical, ferromagnetic or antiferromagnetic stimuli bring new potential functionalities to the spintronic device. An effective […]
The list of things in which humans are unique is fascinating: art, shyness, spirituality, passion for technology, accumulation of objects. There are other activities that we share with other species, but in which we excel because of our ability, complexity and speed: communication and sociability are two good examples. Humans have the most sophisticated language […]
