Mapping the universe"s earliest structures with COSMOS-webb
When NASA's James Webb Space Telescope begins science operations in 2022, one of its first tasks will be an ambitious program to map the earliest structures in the universe. Called COSMOS-Webb, this wide and deep survey of half a million galaxies is.....»»
New JWST observations reveal black holes rapidly shut off star formation in massive galaxies
New research published in Nature showcases new observations from the James Webb Space Telescope (JWST) that suggest black holes rapidly shut off star-formation in massive galaxies by explosively removing large amounts of gas......»»
Advances in understanding the evolution of stomach loss in agastric fishes
Living beings can evolve to lose biological structures due to potential survival benefits from such losses. For example, certain groups of ray-finned fishes show such regressive evolution—medakas, minnows, puffera, and wrasses do not have a stomach.....»»
Astronomers offer new model for formation of recently discovered "free-floating" planets
The recent discovery of a potential new class of distant and mysterious "free-floating" planets has intrigued astronomers since stunning new images captured by the James Webb Space Telescope were shared late last year......»»
New models of Big Bang show that visible universe and invisible dark matter co-evolved
Physicists have long theorized that our universe may not be limited to what we can see. By observing gravitational forces on other galaxies, they've hypothesized the existence of "dark matter," which would be invisible to conventional forms of observ.....»»
War never changes: A Fallout fan’s spoiler-laden review of the new TV series
The show preserved the themes, archetypes, chronology, and more for the games. Enlarge / The nukes went off in 2077 in Fallout's universe. The show tells us more about this event than we've learned from the games before. (credit:.....»»
Mapping plant functional diversity from space: Ecosystem monitoring with novel field-satellite integration
An international team of researchers, led by Professor Jin Wu from the School of Biological Sciences at The University of Hong Kong (HKU), has made a promising advancement in mapping plant functional traits from space using time-series satellite data.....»»
First evidence of ancient human occupation found in giant lava tube cave in Saudi Arabia
If you look from above, you can see thousands of stone structures dotting the landscape of the Arabian peninsula. On the ground, you can find a bounty of stone tools and ancient fireplaces scattered along the edges of ancient lakes, as well as rock a.....»»
The "For All Mankind" universe is about to whole lot bigger
Apple TV+ hit "For All Mankind" has been renewed for a fifth season, and a spin-off is also going back to the beginning for a new look at the Soviet space race.The new "Star City" will go back to the beginning of "For All Mankind," and see life from.....»»
A powerful technique for tracking a protein"s fleeting shape changes
Researchers at Weill Cornell Medicine have developed a powerful, new technique to generate "movies" of changing protein structures and speeds of up to 50 frames per second......»»
Spintronics: A new path to room temperature swirling spin textures
In some materials, spins form complex magnetic structures within the nanometer and micrometer scale in which the magnetization direction twists and curls along specific directions. Examples of such structures are magnetic bubbles, skyrmions, and magn.....»»
James Webb Space Telescope data pinpoint possible aurorae on a cold brown dwarf
Using new observations from the James Webb Space Telescope (JWST), astronomers have discovered methane emission on a brown dwarf, an unexpected finding for such a cold and isolated world. Published in the journal Nature, the findings suggest that thi.....»»
Improved mid-infrared nanoscopy enables 30 times clearer view of the insides of bacteria
A team at the University of Tokyo have constructed an improved mid-infrared microscope, enabling them to see the structures inside living bacteria at the nanometer scale. Mid-infrared microscopy is typically limited by its low resolution, especially.....»»
Why figuring out how potassium is destroyed in stars is important to understanding the universe
If you want to know where elements come from, look to the stars. Almost every element heavier than helium is formed through nuclear reactions in stars. But which stellar processes are responsible for these elements? Can we find patterns in how much o.....»»
Study uses thermodynamics to describe expansion of the universe
The idea that the universe is expanding dates from almost a century ago. It was first put forward by Belgian cosmologist Georges Lemaître (1894–1966) in 1927 and confirmed observationally by American astronomer Edwin Hubble (1889-1953) two years l.....»»
Japan"s Sapporo sees earliest 25C day since records began
Temperatures in Japan's northern city of Sapporo—famous for skiing—on Monday passed 25 degrees Celsius at the earliest point of any year on record, a weather agency official said......»»
Saturday Citations: Listening to bird dreams, securing qubits, imagining impossible billiards
It's Saturday, which means that in a universe where the arrow of time moves backward, people have to go to work tomorrow. In such a hypothetical universe, Garfield hates Fridays—tough to imagine. This week, we looked at several hundred breaking sci.....»»
Chemists devise easier new method for making a common type of building block for drugs
Ring-shaped chemical structures called saturated heterocycles are found in most FDA-approved drugs but are often difficult to create. Scripps Research chemists have just developed a surprisingly easy method for making many of these sought-after compo.....»»
Physicists solve puzzle about ancient galaxy found by Webb telescope
Last September, the James Webb Space Telescope, or JWST, discovered JWST-ER1g, a massive ancient galaxy that formed when the universe was just a quarter of its current age. Surprisingly, an Einstein ring is associated with this galaxy. That's because.....»»
Fast radio bursts: Research introduces a novel approach to characterize their behavior
Fast radio bursts (FRBs) represent the most intense radio explosions in the universe. Since the first discovery in 2007, FRBs have garnered significant attention, culminating in the 2023 Shaw Prize in Astronomy. With yet unknown origin, these extreme.....»»
