The development of artificial intelligence (AI) programs has made it easier for people to access them, leading to the creation of deep fakes. A recent example of this is an AI-generated image of an explosion near the Pentagon that made headlines online and even slightly impacted the stock market until it was quickly deemed a
Researchers in Nuclear, Plasma, and Radiological Engineering, Bioengineering, and Chemistry at the University of Illinois have developed a sustainable way of forming carbon-carbon bonds, which is the foundation of all organic compounds. The researchers have demonstrated a novel metal-catalyst-free approach that could revolutionize organic chemistry. The process could lead to a new era in organic
In the digital age, companies are constantly releasing improved versions of their products to capture value from their digital innovations. This process of generational product innovation (GPI) brings several benefits, such as faster and less costly iteration compared to upgrading hardware. However, a 2021 study from Singapore Management University warns that this strategy can have
Scientists have discovered a new type of brain cell that increases appetite in mice even when their bodies are satiated, according to a recent study. The research, conducted by an international team of scientists, found an abundance of neuropeptide Y neurons in a part of the brain’s hypothalamus called the arcuate nucleus. These neurons produce
Advances in technology have led to the integration of artificial intelligence (AI) algorithms in various sectors, including security applications. Image classification and identification are essential features of AI algorithms used in facial recognition, biometrics, drones, and autonomous vehicles deployed in combat surveillance and military targeting applications. However, these algorithms are vulnerable to cyberattacks. The data
Researchers at the Shanghai Institute of Organic Chemistry of the Chinese Academy of Sciences have developed a new strategy for visible-light-induced selective carbon dioxide (CO2) conversion. The researchers have used an artificial photosynthetic chromatophore nanomicelle system based on the structure of natural photosynthetic purple bacteria to create this system. The study is published in the
Flash droughts have devastating effects on agriculture and are becoming increasingly common as the planet warms. These droughts develop quickly and can cause irreparable damage to a region’s agriculture. In a new study published in Communications Earth & Environment on May 25, 2023, it has been found that the risk of flash droughts is expected
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
