Artist’s impression of a time-resolved circular dichroism measurement of a photoexcited spin-crossover complex. Credit: Ella Maru Studio, Inc. Chiral molecules exist in two forms, called enantiomers, which are mirror images of each other and non-superimposable—much like a pair of hands. While they share most chemical and physical properties, enantiomers can have adverse effects in (bio)chemical …

An international team of astronomers says it has just solved a solar mystery that’s stood for well over a decade. There are two ways to work out what the Sun is made of. The first, called spectroscopy, looks at the Sun’s spectrum. Precise wavelengths of light are missing from this spectrum because they’ve been swallowed …

We’ve been following along with the progress of The Day We Fought Space! from developer Tursiops Truncatus ever since it was first announced in early 2019, with the original hope that it would launch by the end of that year. Well, it didn’t quite make it in 2019 and then 2020 rolled around and… yeah, …
Gamma-rays are the most energetic light wave produced in the universe. So energetic, in fact, that they are seen in certain radioactive decays, in many cosmic explosions, and also in lightning. Lightning in particular has been a bit of a head-scratcher, as no one knows how it produces gamma-rays. The terrestrial gamma-ray flashes (TGFs) are …

Researchers can process 100 images covering 1 centimeter x 1 centimeter-sized samples like this one in around nine minutes using a new system that greatly simplifies the often tedious search for monolayers in the lab. Credit: University of Rochester photo / J. Adam Fenster One of the most tedious, daunting tasks for undergraduate assistants in …

Somewhere out in the cosmos, there’s the physics equivalent of a unicorn. Catching even a glimpse of this oddity that looks like the isolated tip of a magnet would be like a beacon in the night, pointing the way to grand, unifying theories of absolutely everything. Yet aside from one tiny exception in the early …

Underneath our feet, thousands of kilometers deep, molten iron and nickel move about in the Earth’s outer core. This motion creates our planet’s magnetic field – a shield that has protected life against the worst of cosmic radiation for billions of years. Understanding the geomagnetic field is still a work in progress, and new research …

Four cubic colloids made from glass. Credit: TU Delft Researcher Laura Rossi and her group at TU Delft have found a new way to build synthetic materials out of tiny glass particles—so-called colloids. Together with their colleagues from Queen’s University and the University of Amsterdam, they showed that they can simply use the shape of …

A representation of the evolution of the universe over 13.77 billion years. The far left depicts the earliest moment we can now probe, when a period of “inflation” produced a burst of exponential growth in the universe. (Size is depicted by the vertical extent of the grid in this graphic.) For the next several billion …
