Orbitronics devices use an electron’s orbital angular momentum to store and process more information, much more efficiently. Typically, generating orbital currents requires magnetic metals that are heavy and expensive. For the first time ever, researchers prove that atomic vibrations can transfer orbital angular momentum directly to electrons in a non-magnetic material, quartz. The method will work on other chiral materials, such as tellurium, selenium and hybrid organic/inorganic perovskites, and is the most streamlined system yet for orbitronics research.

When a plant's immune system is triggered, its growth is stunted. Colorado State University researchers have discovered how to turn on a hormone that allows plants to keep growing as they defend against disease and pests – a breakthrough that could increase crop production.

Antarctica’s pale expanses of ice keep water locked up and reflect heat from the planet — but the climate crisis is putting these safeguards at increasing risk. Antarctica is warming much faster than the global average, which could destroy its ecosystems and put other parts of the planet at risk by driving sea level rise and damaging food chains. Scientists modelling possible climate crisis outcomes for the Antarctica Peninsula show just how high the stakes are if we don’t act now.

Each molecule has its own unmistakable tone, but the voices of individual molecules are so faint that traditional infrared spectroscopy can only detect the collective chorus of millions or billions of molecules at once. Now researchers at UC San Diego, led by Shaowei Li, have found a way to hear a single molecule sing, using an approach they call infrared-integrated STM, or IRiSTM.
