Scientists have used a high-speed “electron camera” and quantum simulations to capture the photochemical “transition state” of a molecule’s atoms during a ring-opening reaction in α-terpinene. This marks the first time scientists have precisely tracked molecular structure through a photochemical ring-opening reaction, which occurs when light energy is absorbed by a substance’s molecules. The findings,
While going for a run can trigger a runner’s high for some people, others may experience a headache instead. Exercise-induced headaches or exertion headaches were first described in 1968. These headaches occur during or after an intense period of physical activity, such as running, sneezing, heavy lifting, or sex. The symptoms of exertion headaches can
NASA has launched the final two satellites in a quartet designed to track tropical cyclones every hour. The TROPICS constellation of satellites, which are the size of shoeboxes, were sent into orbit on a rocket built by US company Rocket Lab and launched from New Zealand’s Mahia Peninsula. This project has the potential to significantly
Elon Musk’s start-up Neuralink has been granted approval from the US Food and Drug Administration (FDA) to test its brain implants in humans. This is a significant milestone for the company, which aims to develop technology that will allow brains to interface directly with computers. Musk has previously stated that the ultimate goal of the
Tiny particles, which are harmful anthropogenic pollutants, come from factory stacks, car exhaust pipes, and cruise liner engines. These particles settle in the small vessels of our lungs when we breathe in air and make us sick. Air pollution has been known for many years to be harmful to human health. For instance, American researchers
Danish artists in the 19th century might have used leftover brewing byproducts to prepare their canvases, according to a new study. Researchers who examined paintings from the Danish Golden Age discovered traces of yeast and grains. The study, which was published in the journal Science Advances, suggests that artists used byproducts from local breweries to
Researchers from the University of Groningen, along with colleagues from the universities of Nijmegen and Twente in the Netherlands and the Harbin Institute of Technology in China, have discovered a new superconductive state that could have significant applications in the field of superconducting electronics. The team has presented evidence for a variant of the FFLO
A study led by researchers from the Swiss Federal Institute of Technology Lausanne (EPFL) has shown promise for a pair of implants that could transform the lives of individuals with paralysis. The study involved a 40-year-old man named Gert-Jan, who had been paralyzed by a biking accident over a decade ago. Gert-Jan had regained some
Millimeter wave (mmWave) radio frequencies are widely used in modern cars and autonomous vehicles to enable advanced features such as self-driving and assisted driving. However, the use of these frequencies also exposes these vehicles to potential cyberattacks, which can compromise the safety of passengers and pedestrians. To address this issue, researchers from the lab of
In the world of quantum computing, it is important to have scalable photonic quantum computing architectures that rely on low-loss, high-speed, reconfigurable circuits and near-deterministic resource state generators. Recently, in a report published in Science Advances, Patrik Sund and his team at the center of hybrid quantum networks at the University of Copenhagen and the
A new study conducted by Neil J. Lant and his team at Procter & Gamble’s Newcastle Innovation Center suggests that condenser dryers, while reducing airborne microfibers compared to vented dryers, are significant contributors to waterborne microfiber pollution. The study found that both dryer types produce microfiber pollution, including water pollution from rinsing lint traps in
Efficient energy conversion devices for powering electronic devices and heating homes necessitate a detailed understanding of how molecules move and vibrate when undergoing light-induced chemical reactions. Researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have successfully visualized the distortions of chemical bonds in a methane molecule after it absorbs light, loses
EPFL scientists have developed a new technique for creating “density waves” in an atomic gas that could revolutionize our understanding of quantum matter. The research was published in the journal Nature on May 24. According to Professor Jean-Philippe Brantut at EPFL, “Cold atomic gases were well known in the past for the ability to ‘program’
Researchers at Oregon State University and Baylor University have discovered a groundbreaking technique to lower the energy consumption of photonic chips utilized in data centers and supercomputers. The study has been published in the Scientific Reports journal. Data centers can consume up to 50 times more energy per square foot of floor space than a
Surgical incisions are an essential aspect of wound healing, but not all incisions are the same. While a straight cut may be preferred by some, a zig-zagging path can reduce scar tissue, making it a preferred method for some cosmetic procedures. A recent study by researchers at Nanyang Technological University, Singapore (NTU Singapore) has found
