Physicists 'Shine' Light on Inner Details and Breakup of Simple Nucleus
Scientists have found a new way to 'see' inside the simplest atomic nuclei to better understand the 'glue' that holds the building blocks of matter together. The results come from collisions of photons (particles of light) with deuterons, the simplest atomic nuclei (made of just one proton bound to one neutron).
Artificial neurons go quantum with photonic circuits
In recent years, artificial intelligence has become ubiquitous, with applications such as speech interpretation, image recognition, medical diagnosis, and many more. At the same time, quantum technology has been proven capable of computational power well beyond the reach of even the world's largest supercomputer. Physicists at the University of Vienna have now demonstrated a new device, called quantum memristor, which may allow to combine these two worlds, thus unlocking unprecedented capabilities. The experiment, carried out in collaboration with the National Research Council (CNR) and the Politecnico di Milano in Italy, has been realized on an integrated quantum processor operating on single photons. The work is published in the current issue of the journal "Nature Photonics".
Scientists Uncover Surprising New Clues to Exotic Superconductors' Superpowers

Searching for Mach Waves Inside a Perfect Liquid
Scientists have created a new way to examine Mach waves in quark-gluon plasma. This plasma has almost no resistance to flow, making it the world's most perfect fluid. The shape of a Mach wave can offer important information about quark-gluon plasma. Because quark-gluon plasma existed in the early universe a fraction of a second after the Big Bang, understanding its properties helps scientists understand how the universe formed.
Using Marinated Eggs to Demonstrate Diffusion
In American Journal of Physics, researchers were inspired by marinated eggs to demonstrate how diffusion works in an easy and quantifiable way. The basis of the recipe is marinating hard boiled eggs in vinegar or brine, which cures the eggs by sufficiently saturating the egg whites via diffusion. In their experiment, the researchers compared penetration levels of red food dye in the whites of peeled hard-boiled eggs at three different temperatures: refrigerator temperature, room temperature, and in a cool convection oven.

Seen and 'herd': Collective motion in crowds is largely determined by participants' field of vision
Like flocks of birds or schools of fish, crowds of humans also tend to move en masse -- almost as if they're thinking as one. Scientists have proposed different theories to explain this type of collective pedestrian behavior.
Bionic Wing Flaps Improve Wind Energy Efficiency
In the Journal of Renewable and Sustainable Energy, scientists from China show a bionic approach combining features of a seagull's wing with an engineered flow control accessory, known as a Gurney flap, can greatly improve wind turbine performance. To achieve the best aerodynamic performance, the scientists simulated the use of the combined flow control accessory in a variety of situations, including high and low angle of attack and pre- and post-stall scenarios. They compared their computational simulations to experimental results for an aircraft wing undergoing a dynamic stall.
Blowing Bubbles in Dough to Bake Perfect Yeast-Free Pizza
In Physics of Fluids, researchers in Italy developed a method to leaven pizza dough without yeast. The team, which included its very own professional pizza-maker/graduate student, prepared the dough by mixing water, flour, and salt and placing it in a hot autoclave, an industrial device designed to raise temperature and pressure. From there, the process is like the one used to produce carbonation in soda. Gas is dissolved into the dough at high pressure, and bubbles form in the dough as pressure is released during baking.

Collisions of "Isobars" Produce Surprising Result
Scientists compared collisions of ruthenium-96 ions with collisions of zirconium-96 ions, which have four fewer protons, expecting to see a greater separation of charged particles emerging from ruthenium collisions because its greater proton number generates a stronger magnetic field. The results instead showed slightly more charge separation in zirconium collisions. This suggests there may be more differences between these two "isobar" nuclei than just their proton numbers.
