First successful simulations of how various shapes of galaxies are formed

First successful simulations of how various shapes of galaxies are formed
2023-03-30
(Press-News.org) The standard cosmology can answer almost nothing about how the structure of a galaxy is formed. It expects a supermassive black hole at the center and dark matter in the halo to explain the circulation of stars and its velocity. However, why the visible matters are distributed in such a thin plane by the interaction with the black hole while dark matter results in a spherical distribution is a critical open question for a disc galaxy. The formation process of elliptical, ring, and long–barred galaxies also remains unknown.

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. The new force is named as the fundamental force, presentations of which are electric, magnetic, strong, and weak forces. Energy movements form energy circulations according to the fundamental force. As the space expands, an early energy circulation decomposes to local circulations simultaneously on the whole circumference, called the cyclic decomposition. After plural rounds of cyclic decomposition, the resulting energy circulations, which are named as the galactic seed, start to release daughter circulations, known as stellar seeds.

A high energy galactic seed separates into two galactic seeds as the space expands. There are three types of galaxies as the origin of stellar seed release; isolated single galactic seed, binary rotating seeds, and two attached seeds. There are two types of stellar seed releases; the linear release and the ring release, where stellar seeds are released simultaneously on the entire circumference. Depending on the type of galactic seeds and the linear or ring releases of stellar seeds, various shapes of stellar distribution are obtained.

Intermittent ring releases of a single galactic seed gave a disc galaxy. Two attached galactic seeds showed typical patterns of spiral disc galaxies after intermittent ring releases (double disc galaxy). If the two seeds are rotating, spiral arms came out. (See the attached figure.)

Galaxies by intermittent ring releases of stellar seeds from two attached galactic seeds (double disc galaxy, Type 3–1). (a) no rotation of the two galactic seeds Ω1.1 = 0, (b) —(e) rotation by Ω1.1 = π/12, π/8, π/6, π/4.

These should be worthwhile to be checked and validated by physicists because there is no other model that has theoretically and systemically demonstrated the observed features of the universe.

Can a solid be a superfluid? Engineering a novel supersolid state from layered 2D materials
2023-03-30
A collaboration of Australian and European physicists predict that layered electronic 2D semiconductors can host a curious quantum phase of matter called the supersolid. The supersolid is a very counterintuitive phase indeed. It is made up of particles that simultaneously form a rigid crystal and yet at the same time flow without friction since all the particles belong to the same single quantum state. A solid becomes ‘super’ when its quantum properties match the well-known quantum properties of superconductors. A supersolid simultaneously has two orders, solid and super: solid because of the spatially repeating pattern ...

New RNA-based toolkit to regulate gene activity could advance regenerative medicine, gene therapy and biotechnology

New RNA-based toolkit to regulate gene activity could advance regenerative medicine, gene therapy and biotechnology
2023-03-30
The Okinawa Institute of Science and Technology (OIST), in collaboration with Astellas Pharma Inc., has developed a new toolkit that uses small molecules to control the activity of a piece of synthetic RNA, and ultimately regulate gene expression. The technology, which was described in the Journal of the American Chemical Society on March 30, 2023, worked in mammalian cell cultures and in mice. The ability to precisely control whether a gene is turned on or off is expected to lead to more efficient production of compounds that are made using animal cells, and make gene therapy, cell therapy, and regenerative medicine safer. For genes to be expressed, cells make many RNA copies of a section ...

Babies’ gut microbiome not influenced by mothers’ vaginal microbiome composition

2023-03-30
It has been a longstanding assumption that birth mode and associated exposure of newborns to their mothers’ vaginal microbiome during delivery greatly affects the development of babies’ gut microbiome. To test the scientific validity of this assumption, a team of Canadian researchers has now published a study in Frontiers in Cellular and Infection Microbiology in which they examined the effect of maternal vaginal microbiome composition on the development of infants’ stool microbiome at 10 days and three months after birth. “We show that ...

Researchers use tiny diamonds to create intracellular sensors Optically trapped nanodiamonds could be used to measure temperature, magnetic fields and other properties inside living cells VANCOUVER -- Researchers have developed a new way to study the intricate dynamics within living cells by using optically trapped nanodiamond particles as intracellular sensors. Using custom built optical tweezers, the research team trapped the particles within the cell at low power while the cell was alive. The work represents an important advancement in quantum sensing, which takes advantage of quantum mechanics to analyze changes at the atomic level.  The researchers used optical tweezers ...

New study identifies key risk factors for surgical site infection following commonly performed surgery

2023-03-30
Arlington, Va., March 30, 2023 – Findings from an analysis of more than 66,000 abdominal hysterectomies performed in New York hospitals reveal key risk factors for surgical site infections (SSIs) following these procedures, including open surgery, obesity, diabetes, gynecological cancer, and age under 45. Published today in the American Journal of Infection Control (AJIC), the data can help inform surgical and clinical decisions to reduce post-operative infections. “Improved understanding of patient-related, clinical, and surgical factors ...

Limit screen use in children under six, says psychologist

2023-03-30
“Children who are in regular contact with mobile phone screens, tablets or computers are more irritable and have worse attention, memory and concentration than those who do not use them.”  Parents should strictly ration or not allow screen time for children aged under six, according to a leading neuropsychologist in a new book.   Dr Álvaro Bilbao, Ph.D., uses current and established research to highlight how the risk of psychological and behavioral issues increases the ...

Most of world’s salt marshes likely to be underwater by 2100, study concludes
2023-03-29
By Emily Greenhalgh WOODS HOLE, MASS. -- Cape Cod’s salt marshes are as iconic as they are important. These beautiful, low-lying wetlands are some of the most biologically productive ecosystems on Earth. They play an outsized role in nitrogen cycling, act as carbon sinks, protect coastal development from storm surge, and provide critical habitats and nurseries for many fish, shellfish, and coastal birds. And, according to new research from the Marine Biological Laboratory (MBL), more than 90 percent of ...
