(Phys.org) —A combination of nanotechnology and a unique twisting property of light could lead to new methods for ensuring the purity and safety of pharmaceuticals.
How to test the twin paradox without using a spaceship
Forget about anti-ageing creams and hair treatments. If you want to stay young, get a fast spaceship. That is what Einstein's Theory of Relativity predicted a century ago, and it is commonly known as "twin ...
New measurement of electron–quark scattering
From matching wings on butterflies to the repeating six-point pattern of snowflakes, symmetries echo through nature, even down to the smallest building blocks of matter. Since the discovery of quarks, the ...
Researchers demonstrate proof of creation of a mirror by optical matter
Snapshots differentiate molecules from their mirror image
(Phys.org) —Small difference, large effect: Most biological molecules occur in two variants, an original and its mirror image. As a result, they are related to one another like the left hand to the right. ...
Mathematician designs event cloaking device without using metamaterials
Team develops new water splitting technique that could produce hydrogen fuel
A University of Colorado Boulder team has developed a radically new technique that uses the power of sunlight to efficiently split water into its components of hydrogen and oxygen, paving the way for the ...
New method of producing stereoisomers developed
Genomes of limpet, leech and worm put spotlight on lophotrochozoans
A new report in the journal Nature unveils three of the first genomes from a vast, understudied swath of the animal kingdom that includes as many as one-quarter of Earth's marine species. By publishing the ge ...
Researchers develop optically switchable chiral terahertz metamolecules
A multi-institutional team of researchers that included scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) has created the first artificial molecules whose chirality can be rapidly switched ...
