Polarization, the orientation of oscillations in a light wave, is a critical factor in various optical applications. It plays a role in everything from sunglasses to advanced optical communication systems. Manipulating the spatial distribution of polarization presents challenges, especially when dealing with non-uniform polarization states. Current polarization modulation devices have limitations, as they only work
Alzheimer’s disease is a devastating condition that affects a growing number of adults over the age of 65 in the US. With no known cure currently available, researchers are constantly searching for new ways to tackle the disorder. A recent study conducted by scientists from the University of California, San Diego (UC San Diego) and
In the realm of biomedical research, the need for bioactive molecular agents that not only offer real-time monitoring but also simultaneous inhibition of oxidative stress and inflammation is of utmost importance. Traditional imaging methods, such as computed tomography and magnetic resonance imaging, have limitations when it comes to precise diagnostics and real-time analysis. To bridge
The skin is an incredible organ that serves as the body’s first line of defense against external pathogens and environmental insults. Not only does it protect us from harm, but it also plays a crucial role in temperature regulation and moisture retention. However, there is a common misconception that lipids, which include fats, oils, and
In a shocking new study, it has been revealed that 52 doctors in the United States have shared misinformation about COVID-19 on various online platforms, including social media. These doctors, who are trained medical professionals, have spread false information about COVID-19 vaccines, treatments, and masks, leading to potentially harmful consequences for public health. This study,
Seismology has long been an integral part of understanding Earth’s geology and climate. Recently, missions like InSight have provided valuable seismic data from the inside of Mars. However, when it comes to Venus, our closest sister planet, its inner workings have remained a mystery. With its sulfuric acid cloud and scorching surface temperatures, exploring Venus
Neutrinos, the tiny and neutrally charged particles accounted for by the Standard Model of particle physics, have long posed a significant challenge for physicists. Despite being some of the most abundant particles in the universe, their elusive nature makes them difficult to detect due to their low interaction probability with other matter. However, recent breakthroughs
Propylene oxide (PO) is a valuable chemical intermediate, and the direct epoxidation of propylene with H2 and O2 has gained interest as a green and efficient method of production. However, the current catalyst used in this process, Au, is expensive and in limited supply. As a result, there is a need for highly-active non-noble catalysts
The melting of ice shelves in Antarctica is a well-known consequence of rising atmospheric temperatures. However, a recent study suggests that there may be another factor contributing to this phenomenon – tidal currents. Researchers from China have found that tidal currents in Prydz Bay, the third largest bay in Antarctica, may be responsible for up
The behavior of electrons’ mass within a solid has a significant impact on the flow of electronic and heat energy. Weyl semimetals have emerged as a fascinating class of materials with unique properties. Physical and chemical properties of Weyl semimetals are governed by Weyl fermions, which behave in interesting and unusual ways. Unlike conventional fermions
Threads, a platform developed by Meta to challenge Twitter’s dominance, entered the social media scene with high expectations. However, its launch was underwhelming, failing to meet the initial excitement. Released solely as a mobile app for iOS and Android devices, Threads struggled to gain traction among users, and its popularity declined rapidly. Despite attracting early
In recent breakthroughs, scientists have made significant progress in restoring the ability to speak for individuals who have lost this vital function due to strokes or neurological disorders such as amyotrophic lateral sclerosis (ALS). By leveraging brain implants and machine learning, these ground-breaking studies offer new hope for people living with paralysis, transforming their ability
