Controlling bubble formation on electrodes
Using electricity to split water into hydrogen and oxygen can be an effective way to produce clean-burning hydrogen fuel, with further benefits if that electricity is generated from renewable energy sources. But as water-splitting technologies improv.....»»
Novel in-situ pH measurement method for high-temperature hydrothermal systems
Alkaline hydrothermal systems are considered ideal environments for the origin of life because they can provide ideal ion gradient conditions for the formation of early life on Earth......»»
Astronomers discover a key planetary system for understanding formation mechanism of mysterious "super-Earths"
A study led by researchers of the University of Liège and the CSIC—using observations from NASA's TESS telescope—presents the detection of a system of two planets slightly larger than Earth orbiting a cold star in a synchronized dance. Named TOI.....»»
Are search engines bursting the filter bubble? Study finds political ideology plays bigger role than algorithms
Political ideology and user choice—not algorithmic curation—are the biggest drivers of engagement with partisan and unreliable news provided by Google Search, according to a study coauthored by Rutgers faculty published in the journal Nature......»»
How plants use sugar to produce roots
Along with sugar reallocation, a basic molecular mechanism within plants controls the formation of new lateral roots. An international team of plant biologists has demonstrated that it is based on the activity of a certain factor, the target of rapam.....»»
New 3D printing technique for manufacturing ultrasmall metallic objects
A research team led by chemist Dmitry Momotenko has developed a new 3D printing technique for manufacturing ultrasmall metallic objects. Using this technique, the researchers aim to substantially increase the surface area of battery electrodes to dra.....»»
Eruption of Tonga underwater volcano found to disrupt satellite signals halfway around the world
An international team has used satellite- and ground-based ionospheric observations to demonstrate that an air pressure wave triggered by volcanic eruptions could produce an equatorial plasma bubble (EPB) in the ionosphere, severely disrupting satell.....»»
Demystifying vortex rings in nuclear fusion and supernovae
Better understanding the formation of swirling, ring-shaped disturbances—known as vortex rings—could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to becoming a viable energy source......»»
Image of darkness and light shows new stars being born in Lupus 3 nebula
A gorgeous new image of a nebular 500 light-years away gives a peek into the process of star formation......»»
A strange quark matter core likely exists in neutron stars
At the end of a star's life, nuclear fusion ceases, and the resulting pressure is no longer sufficient to counteract the gravitational force. This collapse can lead to the formation of neutron stars, which are composed of the densest matter in the un.....»»
Exploring the centromere and its role in the formation of new species
Centromeres, the DNA sections often found at the center of the chromosomes, display enormous interspecies diversity, despite having the same vital role during cell division across almost the entire tree of life. An international team of researchers h.....»»
James Webb"s "too massive" galaxies may be even more massive
The first results from the James Webb Space Telescope have hinted at galaxies so early and so massive that they are in tension with our understanding of the formation of structure in the universe. Various explanations have been proposed that may alle.....»»
French painters inspire new insights into the physics of soap bubbles
It's one step closer to better control of bubble size, shape for practical applications. Enlarge / Still life of a boy blowing a bubble (circa 1734) by 18th century French painter Jean Siméon Chardin. (credit: Public domain).....»»
Basic "toolkit" for organ development is illuminated by sea star
One of the most basic and crucial embryonic processes to unfold in virtually every living organism is the formation of hollow, tubular structures of various kinds. These tubes may form blood vessels or a digestive tract, and through branching and dif.....»»
A ‘Monumental’ Math Proof Solves the Triple Bubble Problem
A decades-old conjecture about the best way to minimize the surface area of a three-bubble cluster seemed unprovable—until a breakthrough result......»»
Researchers generate cattle blastoids in lab to aid farm animal reproduction
UT Southwestern Medical Center stem cell and developmental biologists and colleagues have developed a method to produce bovine blastoids, a crucial step in replicating embryo formation in the lab that could lead to the development of new reproductive.....»»
Why champagne has stable “bubble chains” and other carbonated drinks do not

AI plus MRI yields the ability to recognize what the mind is hearing
System can also reconstruct speech a person imagines. Enlarge (credit: Getty Images) We have various ways of seeing what the brain is up to, from low-resolution electrodes that track waves of activity that ripple across.....»»
Behind the formation and protection of microtubules
Cellular life hinges on a network of hollow cables called microtubules dynamically lengthening and shortening according to the needs of the moment. During cell division, for instance, these cables latch onto chromosomes and retract—yanking chromoso.....»»
Study suggests catalyst for human brain evolution
More than a million years ago, large chunks of the human genome were rearranged—a chance event during egg or sperm formation that led to the deletion, duplication, or reversal of sections of DNA. Those structural variants, researchers have now disc.....»»
