This incredibly detailed image of an ant obtained at the ESRF’s ID19 beamline is based on a technique called X-ray grating interferometry, which provides high-sensitivity differential phase and dark-field (small angle X-ray scattering) signals. It therefore bears tremendous potential for imaging tiny density differences and structures at the nanoscale that produce low absorption contrast.
20 years of battery life! The NanoTritium betavoltaic power source from City Labs is a thumb-sized battery that draws on the energy released from its radioactive element to provide continuous nanoWatt power for over 20 years.
I told you, be careful not mix Gravity Waves (a fluid dynamics effect) with Gravitational Waves (a prediction from Einstein’s General Relativity). The editor of the article has fallen squarely on this error.

This graphic shows the secondary process by which XFEL light can drive the energy release from a sample containing a nuclear isomer. In the first step (top), photons knock electrons out of inner atomic shells. leading to a plasma of free electrons and ionized atoms. This interaction does not directly affect the nucleus, as it remains in the metastable isomeric state (top right). However, when electrons from the plasma are later captured in the inner-shell vacancies, their excess energy can excite the nucleus to a higher, but less stable, energy state (middle). In the last step, the nucleus relaxes to its ground state, releasing photons in a cascade (bottom).
More than a thousand end caps that make up this Rice University logo represent a fraction of those surveyed by Rice researchers who determined that the energies employed in cap formation do not contribute to the chirality of carbon nanotubes. Chirality refers to the angle of hexagons in nanotubes and dictates their electronic and other desirable properties.

Cryo-SEM image of rapid frozen Barley leaf (Hordeum vulgare) - with Trichomes (hair like structure) and stomata pores on the epidermal surface. Very fine wax crystallites are also visible on the surface of the leaf and in red fungal mildew spores with sprouting fresh infectious tube. A short fungal tube is spreading along a groove formed by adjacent plant cells and not towards the stomata structure.
