A new method has been developed to map the optical absorption of molecules in the electric field of an ultrashort terahertz pulse, which helps determine the strength and dynamics of electric interactions. Molecules in water and other polar media are subject to strong electric forces that originate from their liquid environment. At ambient temperature, this
In the movie “Top Gun: Maverick,” Maverick, played by Tom Cruise, trains young pilots to fly their jets deep into a rocky canyon and avoid detection by radar. However, autonomous aircraft would struggle to complete this task because their “straightforward” path to the target would conflict with the need to avoid the canyon walls. To
A group of scientists and engineers, including researchers from The University of Texas at Austin, have developed a new class of materials that can absorb low energy light and turn it into higher energy light. The group achieved this through combining ultra-small silicon nanoparticles and organic molecules, closely related to those used in OLED TVs.
Artificial Intelligence (AI) is a powerful tool that can be misused for criminal purposes. The biggest risk experts see in AI is its ability to blur the lines between what is real and what is not. Cybercriminals, in particular, can use AI to spread disinformation. A new breed of scams has emerged in the US,
Claims that the US government has secretly retrieved crashed alien spacecraft and their non-human occupants have been around for a long time. These claims are deeply entrenched in post-war American UFO lore and conspiracy theory, inspiring the most well-known narrative in ufology: the “Roswell incident.” However, journalists Leslie Kean and Ralph Blumenthal have injected fresh
The use of automated systems and artificial intelligence has become pervasive in modern-day society. These systems are embedded into our daily routines and show no signs of slowing down. However, this increased use of AI presents technologists and developers with two ethical dilemmas. Firstly, how do we ensure that robots behave in line with our
The COVID-19 pandemic has brought a significant change in the working environment globally. The workforce has shifted from office-based work to remote work. While some employees have been excited about the shift, others find it challenging to adapt to the new employment environment. This article explores the challenges of bringing employees back to the office,
Stars are celestial bodies that have fascinated humans for centuries. They appear as cut jewels, glittering coldly against the velvet darkness of the night sky. However, as stars cool, some of them gradually harden and crystallize. In recent years, astronomers have discovered a white dwarf composed primarily of carbon and metallic oxygen just 104 light-years
Scientists have discovered that a shortage of the amino acid taurine causes animals to age more quickly. However, researchers have also found that oral taurine supplements can delay the aging process and increase the healthy lifespan of animals. This discovery is significant because scientists have been searching for ways to increase health span, the length
Sleeping sickness, also known as Human African trypanosomiasis (HAT), is a neglected tropical disease that plagues sub-Saharan Africa. It is caused by Trypanosoma, a microscopic parasite that enters the bloodstream through the bite of a tsetse fly. For months or even years, the parasite produces few to no symptoms, allowing it to prepare for its
Irritable Bowel Syndrome (IBS) is a common disorder that affects millions of people worldwide. Despite extensive research, the cause and mechanism of IBS are still not fully understood. However, gastroenterologist Brennan Spiegel of the Cedars-Sinai Medical Center in Los Angeles has put forth a new hypothesis in his paper published in The American Journal of
Getting into a regular exercise routine has numerous benefits for both mental and physical health. A recent study has found that regular physical activity can increase an individual’s threshold for pain tolerance. The research was carried out by institutions in Norway and involved 10,732 adults, with two sets of data collected seven to eight years
Researchers from the Ben-Gurion University of the Negev in Israel conducted a clinical trial to investigate the impact of a Mediterranean diet on brain aging. Their findings, published in the journal Clinical Interventions in Aging, revealed that consuming a diet rich in fresh vegetables, seafood, and whole grains, and low in processed foods, can slow
Scientists and engineers in the telecommunications industry are already working on the technologies that will be used for the sixth generation (6G) networks. Ideally, 6G should deliver data rates of over 100 gigabits per second (Gb/s) and support extremely low latencies for applications such as autonomous cars and virtual reality. The new transceiver design capable
In a recent study published in the Advanced Functional Materials journal, a joint team of researchers from the Department of Chemical Engineering at POSTECH and the Department of Nano Engineering at Sungkyunkwan University (SKKU) have developed a technology for high-performance organic polymer semiconductors that exhibit both stretchability and electrical functionality. The team was led by
