New organic compounds found in Enceladus ice grains

New kinds of organic compounds, the ingredients of amino acids, have been detected in the plumes bursting from Saturn's moon Enceladus. The findings are the result of the ongoing deep dive into data from NASA's Cassini mission.

Miniaturized version of ribosome found in microsporidia

A research team lead by MIMS/SciLifeLab research group leader Jonas Barandun, Umeå University, Sweden, uses cryo-electron microscopy to provide near atomic details of the smallest known eukaryotic cytoplasmic protein synthesis ...

Crystal with a twist: scientists grow spiraling new material

With a simple twist of the fingers, one can create a beautiful spiral from a deck of cards. In the same way, scientists at the University of California, Berkeley, and Lawrence Berkeley National Laboratory (Berkeley Lab) have ...

Nanoscale sculpturing leads to unusual packing of nanocubes

From the ancient pyramids to modern buildings, various three-dimensional (3-D) structures have been formed by packing shaped objects together. At the macroscale, the shape of objects is fixed and thus dictates how they can ...

Light-based production of drug-discovery molecules

Photoelectrochemical (PEC) cells are widely studied for the conversion of solar energy into chemical fuels. They use photocathodes and photoanodes to "split" water into hydrogen and oxygen respectively. PEC cells can work ...

Tiny particles can switch back and forth between phases

Three years ago, when Richard Robinson, associate professor of materials science and engineering, was on sabbatical at Hebrew University in Israel, he asked a graduate student to send him some nanoparticles of a specific ...
