Topological insulators, or TIs, have two faces: Electrons flow freely along their surface edges, like cars on a superhighway, but can't flow through the interior of the material at all. It takes a special set of conditions to create this…

Newly discovered magnetic interactions in the Kagome layered topological magnet TbMn6Sn6 could be the key to customizing how electrons flow through these materials. Scientists from the U.S. Department of Energy's Ames National Laboratory…

In 2013, a team of microbiologists led by Professor Volker Müller from Goethe University Frankfurt discovered an unusual enzyme in a heat-loving (thermophilic) bacterium: the hydrogen-dependent CO2 reductase HDCR. It produces formic acid…

As our devices become smaller, faster, more energy efficient, and capable of holding larger amounts of data, spintronics may continue that trajectory. Whereas electronics is based on the flow of electrons, spintronics is based on the spin…

Though they are discrete particles, water molecules flow collectively as liquids, producing streams, waves, whirlpools, and other classic fluid phenomena. Not so with electricity. While an electric current is also a construct of distinct…

Although most fundamental mathematical equations that describe electronic structures are long known, they are too complex to be solved in practice. This has hampered progress in physics, chemistry and the material sciences. Thanks to modern…

Astronomers have made an exciting new discovery, identifying a newborn pulsar that may possibly be only 14 years old. Scientists were finally able to observe the pulsar after the dense debris and bright energy emissions from the supernova…

Most people carry the fungus Candida albicans on their bodies, without this causing many problems. However, a systemic infection with this fungus is dangerous and difficult to treat. Few antimicrobials are effective and drug resistance is…

Holding the right material at the right angle, Cornell researchers have discovered a strategy to switch the magnetization in thin layers of a ferromagnet -- a technique that could eventually lead to the development of more energy-efficient…

Electron microscopy enables researchers to visualize tiny objects such as viruses, the fine structures of semiconductor devices, and even atoms arranged on a material surface. Focusing down the electron beam to the size of an atom is vital…
