Search for heavy bosons sets new limits
Since discovering the Higgs boson in 2012, the ATLAS Collaboration at CERN has been working to understand its properties. One question in particular stands out: why does the Higgs boson have the mass that it does? Experiments have measured its mass to be around 125 GeV—yet the Standard Model implies it has much larger mass and requires a very large correction to the mathematics in order to align theory with observation, leading to the "naturalness problem."

2021-06-22 05:15:56 At the edge of the solar system is a violent frontier where two cosmic powers clash. On one side is the solar wind, the constant flood of hot, charged particles flowing out of the sun at hundreds of miles per second. On the other side are the winds of space, blowing with the radiation of billions upon billions of nearby stars. Open / Comment

2021-06-20 18:43:59 In 1937, Dirac formulated the hypothesis that the strength of gravity is inversely proportional to the age of the universe (G ∝ 1/t) and that the mass of the universe is proportional to the square of the universe's age (M ∝ t²) to explain the following coincidences Open / Comment

New super-resolution microscopy method approaches the atomic scale
Scientists at Weill Cornell Medicine have developed a computational technique that greatly increases the resolution of atomic force microscopy, a specialized type of microscope that "feels" the atoms at a surface. The method reveals atomic-level details on proteins and other biological structures under normal physiological conditions, opening a new window on cell biology, virology and other microscopic processes.

Mystery object caused by spontaneous symmetry breaking revealed
Hiromitsu Takeuchi, a lecturer at the Graduate School of Science, Osaka City University, and a researcher at the Nambu Yoichiro Institute of Theoretical and Experimental Physics (NITEP), has theoretically identified the nature of a mysterious topological defect produced by the recently discovered non-equilibrium time evolution of spontaneous symmetry breaking (SSB). Since the SSB realized in this system is like the SSB that has been known to occur in isotropic superconductors and superfluid 4He, it was expected to produce topological defects with vortex-like properties in the fluid, called quantum vortices. However, the topological defect observed in this experiment has a structure that bore little resemblance to the previously mentioned SSB, and its physical properties have been shrouded in mystery. In this research, the idea of applying the Joukowski transform, which is used to calculate the lift of airplane wings, to quantum vortices was introduced for the first time, and the analysis revealed that the most stable state of this mysterious topological defect is a new topological defect called a quantum elliptic vortex. The results of this research were published online in Physical Review Letters, considered to be one of the most prestigious journals in the field of physics.

Researchers discover that a mechanical cue is at the origin of cell death decision
In many species including humans, the cells responsible for reproduction, the germ cells, are often highly interconnected and share their cytoplasm. In the hermaphrodite nematode Caenorhabditis elegans, up to 500 germ cells are connected to each other in the gonad, the tissue that produces eggs and sperm. These cells are arranged around a central cytoplasmic "corridor" and exchange cytoplasmic material fostering cell growth, and ultimately produce oocytes ready to be fertilized.

Solar storms are back, threatening life as we know it on Earth
A few days ago, millions of tons of super-heated gas shot off from the surface of the sun and hurtled 90 million miles toward Earth.

The black hole at the center of the M87 galaxy is about the size of our solar system, yet it produces a 5,000-light-year-long jet of white-hot plasma, shown here in a computer simulation. At scale, that’s like the Statue of Liberty popping out of a marble. Recent data from the Event Horizon Telescope provides the first empirical evidence for one of the most popular explanations of where black hole jets like this one come from.
