When Israeli scientist Daniel Shechtman first saw a quasicrystal through his microscope in 1982, he reportedly thought to himself, "Eyn chaya kazo"—Hebrew for, "There can be no such creature."
Researchers have developed a new terahertz imaging approach that, for the first time, can acquire micron-scale resolution images while retaining computational approaches designed to speed up image acquisition. This combination could allow terahertz imaging to be useful for detecting early-stage skin cancer without requiring a tissue biopsy from the patient.
Vacuum-based transport systems could clear the way for faster, cheaper travel – or so proponents claim. Jon Cartwright takes a closer look

X-rays make the invisible visible: they permit the way materials are structured to be determined all the way down to the level of individual atoms. In the 1950s it was x-rays which revealed the double-helix structure of DNA. With new x-ray sources, such as the XFEL free-electron laser in Hamburg, it is even possible to "film" chemical reactions.

High school students nationwide will study the effects of the solar eclipse on cosmic rays. While most people are marveling at Monday’s eclipse, a group of researchers will be measuring its effects on cosmic rays—particles from space that reach collide with the earth’s atmosphere to produce muons, heavy cousins of the electron.

An analysis of electron-positron collision data has determined the spin and parity of a particle thought to consist of four quarks. [Physics] Published Wed Aug 16, 2017
A potential new state of matter is being reported in the journal Nature, with research showing that among superconducting materials in high magnetic fields, the phenomenon of electronic symmetry breaking is common. The ability to find...Show More Summary
(Phys.org)—In quantum mechanics, it's impossible to precisely and simultaneously measure the complementary properties (such as the position and momentum) of a quantum state. Now in a new study, physicists have cloned quantum states and...Show More Summary
An advanced particle accelerator designed at the U.S. Department of Energy's Brookhaven National Laboratory could reduce the cost and increase the versatility of facilities for physics research and cancer treatment. It uses lightweight,...Show More Summary
Researchers are on the lookout for rapid, reliable and affordable switches for the opto-electronics of the future. An Empa team now presents a potential solution: dye droplets measuring just a few sub-micrometers in diameter.
