Granular materials such as sand have long been a subject of interest for scientists due to their unique properties. While we can easily walk on solid sand at the beach, the same sand grains can flow like a liquid in an hourglass. This duality of behavior has intrigued researchers for years. In a recent study
In recent studies, researchers have made a groundbreaking discovery regarding the creation of spherical carbon ‘cages’ known as fullerenes. By combining laboratory experiments on the infra-red glow of carbon molecules with simulation software, the team has shed light on the process by which fullerenes are formed. This discovery has significant implications for our understanding of
In a surprising turn of events, Tesla reported a significant drop in first-quarter auto sales, with global deliveries totaling 386,810, down 8.5 percent from the previous period. This decline was attributed to various factors, including weak demand in China, increased competition from local electric vehicle (EV) makers, and production setbacks caused by external factors such
California, a state known for its aggressive greenhouse gas reduction policies, is ironically the nation’s greatest emitter of sulfuryl fluoride, a common pesticide used for treating termites and other wood-infesting insects. Despite being a national leader in reducing greenhouse gas emissions, California has been identified as the primary source of 60-85% of sulfuryl fluoride emissions
Recent reports on social media platforms like TikTok have brought attention to unexpected pregnancies in women using semaglutide-based drugs like Wegovy and Ozempic. While these anecdotal reports are concerning, it is important to differentiate between individual experiences and scientific evidence. Mechanism of Action of GLP-1 Agonist Drugs GLP-1 (Glucagon-like peptide-1) agonist drugs like Ozempic mimic
A recent study led by a team of scientists from Boston College has unveiled a groundbreaking discovery in the realm of quantum materials. Through their research, the team identified dual topological phases within an intrinsic monolayer crystal, shedding light on new and unconventional properties that defy existing rules in the field. This finding, published in
Platinum (Pt) electrodes are essential components of hydrogen fuel cells and electrolysis, playing a critical role in the efficiency and stability of clean power technologies. The oxidation of Pt surfaces during these processes has been identified as a major issue, leading to the degradation of catalyst performance over time. In a recent study published in
In a groundbreaking development, a team of engineers at The Barcelona Institute of Science and Technology’s ICFO–Institut de Ciències Fotòniques has unveiled a revolutionary nearly transparent camera designed for eye tracking. The traditional obstacle of obstructing the user’s view has been overcome with this innovative creation, paving the way for a myriad of potential applications
On August 30, 2022, a severe hail event occurred in Gerona, north-eastern Spain, causing significant damage to buildings, cars, and agricultural areas. Individual hailstones reached a massive 12cm, marking the largest ever documented in the country. This unusual phenomenon resulted in 67 injuries and one fatality, highlighting the catastrophic consequences of extreme hail events. Professor
The recent news of a person in Texas contracting bird flu after exposure to dairy cattle has sparked growing concern over the global strain of the virus as it continues to spread to new species. This marks only the second case of a human testing positive for bird flu in the United States, with the
Weather predictions play a crucial role in the daily lives of over a billion people in the Indian subcontinent, particularly during the South Asian monsoon season from June to September. The ability to forecast when heavy rains will occur is vital for agricultural and urban planning, as it allows farmers to schedule their harvests and
In the realm of science and technology, the utilization of coherent light sources in the deep ultraviolet (DUV) region has become increasingly vital across a wide range of applications. From lithography to defect inspection, metrology, and spectroscopy, the significance of DUV lasers cannot be overstated. Traditionally, high-power 193-nanometer (nm) lasers have played a crucial role
Ammonia, a commonly used nitrogen-based chemical in various industries, has long been known for its negative impact on the environment. The traditional methods of producing ammonia involve high temperatures, high pressure, and significant energy consumption, making it one of the major contributors to carbon emissions globally. However, a recent breakthrough by engineers at the University
El Niño, a climate pattern characterized by warmer waters in the eastern Pacific Ocean, has been responsible for bringing record heat and heavy precipitation across the world over the past year. Recent research suggests that melting Arctic sea ice may be contributing to the intensification of El Niño events. A study published in Science Advances
