New calculations predicting the spatial distributions of the charges, momentum, and other properties of the quarks within protons found that the up quarks are more symmetrically distributed and spread over a smaller distance within the proton than the down quark. 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.
Astrophysicists say they have found an answer to why spiral galaxies like our own Milky Way are largely missing from a part of our Local Universe called the Supergalactic Plane.
Particle collisions produce quarks and gluons that interact in structured ways. Scientists have for the first time directly observed a predicted “dead cone" in this structure. This finding helps to confirm a feature of the theory of strong interactions, which explains how quarks and gluons form protons and neutrons.

The world’s total population is expected to reach 9.9 billion by 2050. This rapid increase in population is boosting the demand for agriculture to cater for the increased demand. Below are some of the latest research and features on agriculture and farming in the Agriculture channel on Newswise.
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.

Nonlinear exciton polaritons in TMDs microcavities provide a versatile platform for exploring interacting many-body phenomena. To achieve an appropriate combination of strong nonlinearity with the thermal stability of the polaritons, scientists from Tsinghua University, Wuhan University and Beijing Academy of Quantum Information Sciences jointly developed the artificial mesa cavities to manipulate the nonlinear interaction and the macroscopic coherence of polaritons at ambient conditions. This work will stimulate more developments in realistic polaritonic applications based on the TMDs microcavities.
