Fast light pulse triggers charge transfer into water
In certain molecules, the so-called photoacids, a proton can be released locally by excitation with light. There is a sudden change in the pH value in the solution - a kind of fast switch that is important for many chemical and biological processes.

DUNE collaboration tests new technology for second detector module
Scientists working on the international Deep Underground Neutrino Experiment are developing a vertical drift detector. The new technology may open doors to building large neutrino detectors at a lower cost and in a simpler manner.
DUNE collaboration ready to ramp up mass production for first detector module
The international DUNE collaboration is conducting final tests of the components for its first neutrino detector module, to be installed a mile underground in South Dakota. Preparations for ramping up the mass production of these components are underway.
First successful simulations of how various shapes of galaxies are formed
The Energy Circulation Theory (ECT) claims that there is a force working between momentums whereas the effects of gravitational force is based on magnitudes of energies.
Dissecting the Circadian Clock in Real Time
Scientists have made progress in understanding the circadian clock, the 24-hour cycle that synchronizes with light-dark exposure, and how it functions. They developed a new way to study how the circadian clock synchronizes in real time, revealing surprises about the clock's mechanisms.

Ultrasmall swirling magnetic vortices detected in iron-containing material
A multi-institutional team, including Argonne, has discovered surprising spin properties in thin films of an iron-containing magnetic material. These properties could be applicable as basic units in information storage applications.
Light-bending gravity reveals one of the biggest black holes ever found
A team of astronomers has discovered one of the biggest black holes ever found, taking advantage of a phenomenon called gravitational lensing.
Revealing the nature of fractures caused by hydrogen in high-strength steel
Scientists have observed that hydrogen embrittlement in HS steel often leads to intergranular (IG) fractures, which occur along the grain boundaries of the crystalline lattice. Unfortunately, the underlying mechanisms behind this particular type of fracture are difficult to study in isolation in HS steel because other types of fracture tend to occur alongside it.

Colision de 'Galaxias Taffy' produce un puente con material de formacion estelar
El telescopio de Gemini Norte, la mitad boreal del Observatorio Internacional Gemini, que opera NOIRLab y AURA, capturo esta increible imagen de dos galaxias llamadas UGC 12914 y UGC 12915, pero que tambien se les conoce como las Galaxias Taffy. Su forma retorcida es el resultado de una colision frontal ocurrida hace unos 25 millones de anos antes de que esta imagen fuera tomada. Una union o puente de gas altamente turbulento y desprovisto de formacion estelar significativa se extiende por la brecha que separa ambas galaxias.
'Taffy Galaxies' Collide, Leave Behind Bridge of Star-Forming Material
The Gemini North telescope, one half of the International Gemini Observatory, operated by NSF's NOIRLab, captured this dazzling image of UGC 12914 and UGC 12915, which are nicknamed the Taffy Galaxies. Their twisted shape is the result of a head-on collision that occurred about 25 million years prior to their appearance in this image. A bridge of highly turbulent gas devoid of significant star formation spans the gap between the two galaxies.

Particle Errors: Quantifying the Effects of Simulation Mixing State on Aerosol Optical Properties
Particles in the atmosphere such as black carbon affect global climate by absorbing and radiating light and heat. To calculate the effects of aerosols on climate, scientists rely on simulated aerosol fields, but these models represent mixtures of aerosol particles in simplified ways that can introduce errors. This study quantified the resulting errors in simulated aerosol optical properties, finding errors great enough to warrant more attention.
How cosmic winds transform galactic environments
Much like how wind plays a key role in life on Earth by sweeping seeds, pollen and more from one place to another, galactic winds - high-powered streams of charged particles and gases - can change the chemical make-up of the host galaxies they form in, simply by blowing in a specific direction.
