Urdu“Mirror life”—a synthetic organism, mirror-reversed on the molecular level from natural life—could be possible within decades. It could prove a boon to drug development, but mirror bacteria could also pose unprecedented hazards to ecosystems and human health.

New Technique Lets Scientists Create Resistance-Free Electron Channels
Researchers have taken the first atomic-resolution images and demonstrated electrical control of a chiral interface state – an exotic quantum phenomenon that could help researchers advance quantum computing and energy-efficient electronics.
A new way to identify chiral molecules with light could vastly improve detection efficiency
Chiral molecules are those that have two versions that are mirror images, like our right and left hands.
How Earth’s molecules got their “handedness”
Scientists from The Ohio State University have a new theory about how the building blocks of life – the many proteins, carbohydrates, lipids and nucleic acids that compose every organism on Earth – may have evolved to favor a certain kind of molecular structure.
Mirror Image: FSU study lays out chirality flipping theory
Chemists can make a career out of controlling whether certain molecules are generated as a lefty or a righty. Molecules don’t literally have hands, but scientists often refer to them in this way when looking at molecules that are mirror images of each other and therefore are not superimposable.
New optical computing approach offers ultrafast processing
Logic gates are the fundamental components of computer processors. Conventional logic gates are electronic – they work by shuffling around electrons – but scientists have been developing light-based optical logic gates to meet the data processing and transfer demands of…
Researchers build long-sought nanoparticle structure, opening door to special properties
Researchers have built a unique, long-sought structure from gold nanoparticles. Alex Travesset of Iowa State and the Ames National Laboratory has the equations and illustrations to explain how it all happened. This new nanomaterial could have useful optical, mechanical and electronic characteristics.
Growing pure nanotubes is a stretch, but possible
Like a giraffe stretching for leaves on a tall tree, making carbon nanotubes reach for food as they grow may lead to a long-sought breakthrough.
Truly chiral phonons observed in three-dimensional materials for the first time
Chirality is the breaking of reflection and inversion symmetries.
Scientists Take Control of Magnetism at the Microscopic Level
Atoms in magnetic materials are organized into regions called magnetic domains. Within each domain, the electrons have spins that point in the same direction. Researchers have developed a magnetic material whose thickness determines whether the walls between domains have the same or alternating spin chirality, or handedness. This study demonstrates a way to change the rotational direction and occurrence of domain wall pairs, a finding that could lead to technologies based on spintronics.
