Giant rogue waves: Southern Ocean expedition reveals wind as key cause
A University of Melbourne expedition to the southernmost waters encircling Antarctica has discovered that wind drives the formation of colossal rogue waves, and that these unpredictable waves occur more frequently than scientists had previously thoug.....»»
Researchers find baby stars discharge plume-like "sneezes" of magnetic flux during formation
Kyushu University researchers have shed new light into a critical question on how baby stars develop. Using the ALMA radio telescope in Chile, the team found that in its infancy, the protostellar disk that surrounds a baby star discharges plumes of d.....»»
Novel UV broadband spectrometer improves air pollutant analysis
Sunlight has a major influence on chemical processes. Its high-energy UV radiation in particular is strongly absorbed by all materials and triggers photochemical reactions of the substances present in the air. A well-known example is the formation of.....»»
LSD1 promotes FSH responsive follicle formation by regulating autophagy and repressing Wt1 in granulosa cells: Study
A study published in Science Bulletin has been led by Prof. Chao Wang (China Agricultural University), Prof. Guoliang Xia (China Agricultural University) and Prof. Fengchao Wang (National Institute of Biological Sciences)......»»
Unveiling the hidden threat: Drought-induced inelastic subsidence in expansive soils
A journal article published by University of Houston Department of Earth and Atmospheric Sciences researchers highlights a significant, yet often overlooked, environmental concern—permanent losses in land surface elevation due to inelastic compacti.....»»
The sun was born when a dense gas cloud collapsed 4.6 billion years ago
While the upcoming total solar eclipse is a special moment to reflect on our place in the universe, scientists have been studying the birth of the sun and the formation of our solar system for a long time......»»
Hubble peers at pair of closely interacting galaxies
This image from the NASA/ESA Hubble Space Telescope features Arp 72, a very selective galaxy group that only includes two galaxies interacting due to gravity: NGC 5996 (the large spiral galaxy) and NGC 5994 (its smaller companion, in the lower left o.....»»
Study reports that age is the driving force in changing how stars move within galaxies
Galaxies start life with their stars rotating in an orderly pattern but in some the motion of stars is more random. Until now, scientists have been uncertain about what causes this—possibly the surrounding environment or the mass of the galaxy itse.....»»
Unveiling the sun: NASA"s open data approach to solar eclipse research
As the world eagerly anticipates the upcoming total solar eclipse on April 8, 2024, NASA is preparing for an extraordinary opportunity for scientific discovery, open collaboration, and public engagement. At the heart of the agency's approach to this.....»»
Image: Hubble finds a field of stars
This image from the NASA/ESA Hubble Space Telescope shows a globular cluster called NGC 1651. Like another recent globular cluster image, NGC 1651 is about 162,000 light-years away in the largest and brightest of the Milky Way's satellite galaxies, t.....»»
In a distant stellar system, the JWST sees the end of planet formation
Every time a star forms, it represents an explosion of possibilities. Not for the star itself; its fate is governed by its mass. The possibilities it signifies are in the planets that form around it. Will some be rocky? Will they be in the habitable.....»»
Sleeping supermassive black holes awakened briefly by shredded stars
A new investigation into an obscure class of galaxies known as Compact Symmetric Objects, or CSOs, has revealed that these objects are not entirely what they seem. CSOs are active galaxies that host supermassive black holes at their cores. Out of the.....»»
Astronomers discover 49 new galaxies in under three hours
An international team of astronomers has discovered 49 new gas-rich galaxies using the MeerKAT radio telescope in South Africa. Their research is published in Monthly Notices of the Royal Astronomical Society......»»
How many zebrafish constitute a school? "Three," say physicists
Physicists are also interested in fish—above all when they are researching the formation of structures. A research team from Heinrich Heine University Düsseldorf (HHU) and the University of Bristol (United Kingdom) has examined the schooling behav.....»»
"Dark stars": Dark matter may form exploding stars, and observing the damage could help reveal what it"s made of
Dark matter is a ghostly substance that astronomers have failed to detect for decades, yet which we know has an enormous influence on normal matter in the universe, such as stars and galaxies. Through the massive gravitational pull it exerts on galax.....»»
Breakthrough in light manipulation: Unveiling novel finite barrier bound states
Exploring wave propagation and localization in various media has been a core focus in optics and acoustics. Specifically, in photonics and phononics, scientists have been dedicated to understanding and controlling the behavior of light and sound wave.....»»
Unveiling the formation of the first galaxies
Utilizing high-resolution three-dimensional radiation hydrodynamics simulations and a detailed supernova physics model run on supercomputers, a research team led by Dr. Ke-Jung Chen from the Institute of Astronomy and Astrophysics, Academia Sinica (A.....»»
Fairy circles: Plant water stress causes Namibia"s gaps in grass
Namibia's legendary fairy circles are mysterious, circular, bald patches in the dry grasslands on the edge of the Namib Desert. Their formation has been researched for decades and has recently been the subject of much debate. With extensive fieldwork.....»»
Astrophysicist"s research could provide a hint in the search for dark matter
Dark matter is one of science's greatest mysteries. It doesn't absorb, reflect or emit light, so we can't see it. But its presence is implied by the gravitational effects it appears to have on galaxies......»»
