Researchers uncover role of plasma waves in mysterious heating of sun"s corona
There is a profound mystery in our sun. While the sun's surface temperature measures around 10,000 degrees Fahrenheit, its outer atmosphere, known as the solar corona, measures more like 2 million degrees Fahrenheit, about 200 times hotter......»»
Engineering perovskite materials at the atomic level paves way for new lasers, LEDs
Researchers have developed and demonstrated a technique that allows them to engineer a class of materials called layered hybrid perovskites (LHPs) down to the atomic level, which dictates precisely how the materials convert electrical charge into lig.....»»
Chemists develop chiral DNA catalysts for asymmetric catalysis
Chemists from the National University of Singapore (NUS) have developed a way to make diverse chiral deoxyribonucleic acid (DNA) catalysts by merging DNA repair with biorthogonal chemistry, paving the way for more efficient and versatile approaches t.....»»
Hidden in the teeth: DNA study finds these 19th century lions preyed on humans and giraffes
In 1898, two male lions terrorized an encampment of bridge builders on the Tsavo River in Kenya. The lions, which were massive and maneless, crept into the camp at night, raided the tents and dragged off their victims. The infamous Tsavo "man-eaters".....»»
Expansion technique to image nanoscale structures inside cells makes high-resolution imaging more accessible
A classical way to image nanoscale structures in cells is with high-powered, expensive super-resolution microscopes. As an alternative, MIT researchers have developed a way to expand tissue before imaging it—a technique that allows them to achieve.....»»
Researchers develop technique that enables breeding of genetically identical hybrid plants
When different varieties of one plant species are crossed with each other, their hybrid offspring are often more robust and grow more quickly than their parents. However, in the next generation, this effect disappears again......»»
Advanced model predicts gene architecture via nucleosome position
DNA—the molecule that carries the genetic information of all living organisms—is packaged within cells in a complex manner that allows it to function efficiently. Nucleosomes facilitate DNA compaction and also play a crucial role in regulating ge.....»»
Measures to restore biodiversity in peatlands fall short, study finds
Research by ecologist Tom Heuts of Radboud University shows that several experimental measures taken at Frisian farms to restore biodiversity in former peatlands were unsuccessful. Three methods in which the water levels were raised did not have the.....»»
Spectroscopy study determines how catalysts remove dangerous nitrogen oxides
Catalysts belonging to the zeolite family help to remove toxic nitrogen oxides from industrial emissions. Researchers at the Paul Scherrer Institute PSI have now discovered that their complex nano porous structure is crucial. Specifically, individual.....»»
Assessment of damaged archaeological sites suggests they require individual protection concepts
An analysis of the damage to archaeological sites documented after a heavy rainfall event in July 2021 in parts of Germany shows that several factors increase the risk of damage to archaeological sites due to heavy rainfall and flooding events. For e.....»»
Theoretical study demonstrates existence of giant photocaloric effects in ferroelectric perovskites
Solid-state cooling is a promising alternative cooling technique that does not rely on the use of gases or liquids, like conventional refrigeration systems, but instead utilizes the properties of solid materials to refrigerate. This alternative cooli.....»»

Using a unique combination of DNA techniques to authenticate ginseng supplements and combat adulteration
Rosalee Hellberg, an associate professor in Chapman University's Food Science Program, and her research team have made a significant breakthrough in the fight against adulteration in dietary supplements. Effective methods for identifying adulteration.....»»
Low-temperature synthesis technique uses upcycled textile waste to create green, safe waterproof coating
A new technique could create waterproof coatings for clothes from discarded textiles—far safer for humans and the environment than current coatings, which are typically made with harsh chemicals and carcinogens......»»
Unveiling a new technique for preparing ionic liquid-based membranes for mixture separation
Separating mixtures into their constituent substances is essential in many fields. For example, mixture separation plays a key role in the petrochemical industry, as well as in chemical purification and synthesis plants. Moreover, separating mixtures.....»»
Astronomers race to capture image of exoplanet near star
Planet AF Lep b is a world of firsts. In 2023, it was the lowest-mass planet outside our solar system to be directly observed and have its mass measured using astrometry. This is a technique that charts the subtle movements of a host star over many y.....»»
