A team of chemists from the Russian Academy of Sciences has found that metal atoms, not nanoparticles, play a crucial role in catalysts used in fine organic synthesis. The study, published in the Journal of the American Chemical Society, utilized various types of electron microscopy to track a catalyst’s region during a reaction to understand

Researchers at the University of Maryland (UMD) have come up with a new way of optical guiding using auxiliary ultrashort laser pulses to form a ring of high-intensity light structures called “filaments.” These filaments heat the air molecules to create an extended ring of low-density heated air that surrounds a central undisturbed region, which is
When light interacts with matter, it can produce unique quasi-particles known as polaritons. These particles are half light and half matter. Polaritons have been studied by physicists for a few decades now, with researchers exploring their potential for developing highly performing lasers or other technologies. Development of a High-Performing Device Researchers at the University of
The continents on Earth play an essential role in making the planet habitable for life as we know it. However, very little is known about how these huge pieces of the planet’s crust emerged or what gives them their unique properties. A new study published in Science by Elizabeth Cottrell, a research geologist at the
Space is dominated by supermassive black holes that sit at the centers of galaxies. These behemoths start at around 100,000 times the mass of the Sun and can reach tens of billions of solar masses at maximum. Although we have some ideas about how they got that way, the biggest mystery of the universe is
Three environmental scientists and city planners from the University of California, Berkeley, the University of North Carolina, Chapel Hill, and the University of Miami conducted a study on the impact of electric-powered vehicles (EVs) on air quality. The researchers found that the introduction of EVs had a varying impact on air quality in different neighborhoods,
After conducting an extensive investigation, scientists have confirmed that the Moon is not made of green cheese, as the myth goes. Seismic data has revealed that the inner core of the Moon is actually a solid ball with a density comparable to that of iron. This finding has settled the debate around whether the Moon’s
A new study by researchers at UC Berkeley, UCLA, and Climate Central has found that as sea levels rise, hundreds of toxic sites along the California coast are at risk of flooding, with the most significant potential impact on the state’s most marginalized communities. The Risks The study identified 736 facilities at risk of coastal
Throughout history, humans have never been contacted by extraterrestrial life. However, statistically, it is believed that Earth is not alone in the universe. With so much space to scan, there is a possibility that Earth simply lies in a bubble without any radio waves emitted by extraterrestrial life. This theory has been proposed by Claudio
A recent study published in the journal Ocean-Land-Atmosphere Research has sought to answer why Arctic sea ice is melting at a faster and more obvious rate than Antarctic sea ice. The research has found that the differences in how both regions respond to climate change can be explained through their geographical, climatic, and meteorological differences.
Scientists have discovered rare earth metal terbium in the atmosphere of KELT-9b, an exoplanet located approximately 670 light-years away. This is the first time that the extremely rare element has been found on a distant planet. KELT-9b is known as a hot Jupiter, a gas giant that orbits a blue supergiant star on an extremely
Dementia is a brain disease that affects approximately 55 million people worldwide, leading to the loss of cognitive functions. While early signs of dementia may be subtle, researchers have identified other noticeable changes to the body that can indicate dementia risk. A recent study suggests that hearing difficulties may be a warning sign of dementia
Scientists from SLAC National Accelerator Laboratory have used two ultrafast X-ray spectroscopy techniques to capture the movement of a molecule called ferricyanide. This is the first time that the movement has been recorded in this way, and the team thinks that their approach could help map more complex chemical reactions, such as oxygen transportation in
Chemists at the University of California, Los Angeles have discovered that 1,2,3-cyclohexatriene, a benzene isomer, has the potential to be a useful reagent in organic synthesis. Although it has been considered too unstable to be of use for many years, it is substantially higher in energy than benzene, making it a promising candidate for synthesizing
Astronomers have observed a flare of light as a dying star engulfs and destroys one of its orbiting planets, providing valuable insight into what happens to a planetary system as a star enters its death throes. This is the first time such an event has been observed, despite being theorized for some time. Process of
