Researchers Finally Decode Internal Structure of Kerogen

Kerogen is a waxy, insoluble organic substance dispersed in sedimentary rocks and is the precursor of oil and gas. In a new study, published in the Proceedings of the National Academy of Science, researchers from MIT and elsewhere have captured 3D images of kerogen’s internal structure, with a level of …

Physicists Solve Structure of Unusually Complex Form of Nitrogen

An international team of experimental physicists has for the first time determined the structure of ι-N2, a crystallized version of nitrogen. Turnbull et al synthesized a single crystal of ι–N2 in a diamond anvil cell from ε–N2 at 65 GPa and 477 degrees Celsius. Image credit: Turnbull et al, doi: 10.1038/s41467-018-07074-4. …

Scientists Are About to Redefine the Kilogram

The kilogram is one of the most important and widely used units of measure in the world — unless you live in the US. For everyone else, having an accurate reading on what a kilogram is can be vitally important in fields like manufacturing, engineering, and transportation. Of course, a …

Physicists Create Tractor Beam for Atoms

Rather than sucking space ships into a space-station, a tractor beam created by University of Adelaide researcher Ashby Hilton and his colleagues pulls atoms into a microscopic hole at the center of a special optical fiber. Atomic chamber in which tractor beams were created. Image credit: Institute for Photonics and …

Scientists Confirm Electrons Are Round Instead of Squished

When learning the basics of atomic structure in school, we all pictured electrons as perfectly round. That’s just easier than pondering the ramifications of dark matter on the Standard Model. Scientists have long wondered just how round electrons are, an answer that could affect how we understand subatomic particles. The …

Electrons Are Perfectly Spherical, New Measurements Confirm

Physicists from the Advanced Cold Molecule Electron Electric Dipole Moment (ACME) Collaboration have examined the shape of an electron’s charge with unprecedented precision to confirm that it is extremely round. The result, reported in the journal Nature, supports the strength of the Standard Model of particle physics and seems to …

Universe’s Beginning was Fluid, Physicists Say

Physicists from the ALICE (A Large Ion Collider Experiment) Collaboration at CERN have gained new insights into the properties of the quark-gluon plasma, a state of matter thought to have existed just after the Big Bang. The findings are published in the journal Physics Letters B. An event from the …
