Colliding nuclei at high speeds melts their constituent quarks and gluons into a Quark-Gluon Plasma (QGP). Quarks and gluons from the colliding nuclei also sometimes ricochet off one another very early on in the collision and form sprays of energetic particles known as jets. These jets lose their energy as they exit the plasma, with wide jets losing more energy than narrow jets. Researchers have confirmed that the plasma treats each prong of a jet independently only when the prongs are separated by a sufficiently large angle.

Parag Chitnis of George Mason University led a team that developed a wearable ultrasound system that can produce clinically relevant information about muscle function during dynamic physical activity. The system uses a patented approach that uses long-duration chirps and ultrasound sensing, and it allowed the team to design a simpler, cheaper system that could be miniaturized and powered by batteries. The result is an ultrasound monitor with a small, portable form factor that can be attached to a patient.
Fast ions that heat plasma in a fusion device can resonate with waves in the plasma, potentially causing waves to grow and kick the fast ions out of the device. This research used mathematical calculations and computer simulations to examine these resonant interactions to reveal how different types of collisions compete to determine the way energy transfers between the resonant particles and the plasma waves. The results will aid in models of how to keep plasmas hot enough to sustain fusion reactions.

The results imply that these two types of quarks contribute differently to a proton’s properties.

One of the annoying side effects of being absorbed in a gripping novel is that the cup of tea on the table becomes cold! Unfortunately, the tea would not heat itself by absorbing the heat around it, just as pieces of a broken egg would not put themselves together or milk mixed in coffee would not separate by itself.
A team of astrophysicists led by Núria Miret-Roig from the University of Vienna found that two methods for determining the age of stars measure different things: Isochronous measurement thereby determines the birth date of stars, while dynamical tracking provides information on when stars "leave their nest", about 5.5 million years later in the star clusters studied.

In Physics of Fluids, scientists demonstrate how bloodstains can yield valuable details by examining the protrusions that deviate from the boundaries of otherwise elliptical bloodstains. The researchers studied how these “tails” are formed using a series of high-speed experiments with human blood droplets less than a millimeter wide impacting horizontal surfaces at various angles. They found that the tail length can reflect information about the size, impact speed, and impact angle of the blood drop that formed the stain.

This finding helps to confirm a feature of the theory of strong interactions, which explains how quarks and gluons form protons and neutrons.

In 2008 NASA’s Spitzer Space Telescope found a protoplanetary disk unlike any other. The dusty disk of gas surrounding the young Sun-like star SZ Chamaeleontis (SZ Cha) was being pummeled by extreme ultraviolet radiation – something previously seen only in computer models, never in the real universe. Planets in this system would have more time to form than in a disk being evaporated by X-rays, which is the norm. However, when the James Webb Space Telescope followed up on SZ Cha, it found nothing out of the ordinary – no abundance of ultraviolet radiation. In a short space of cosmic time, conditions in SZ Cha’s disk had changed, leaving astronomers to untangle meaning from the mismatched data and its implications for the formation of other solar systems.
