A recent randomized controlled trial has provided further evidence supporting the argument that circumcision can potentially reduce the risk of HIV infection among men who have sex with men. While previous observational studies have hinted at the protective effects of circumcision in preventing the transmission of STIs, including HIV, among this population, there have been

In a groundbreaking development, a team of researchers led by Professor Han Gi Chae and Professor Jong-Beom Baek at UNIST has developed a new technology to address the limitations of current catalyst electrodes. This advancement, reported in the Journal of the American Chemical Society, enables the production of green hydrogen on a large scale at
Renewable hydrogen is anticipated to play a crucial role in mitigating carbon emissions in Europe. Previous research from the Joint Research Centre (JRC) suggests that sourcing hydrogen from regions with cheaper renewable energy may be more cost-effective than local production. However, concerns have emerged regarding the environmental impact of transporting large quantities of hydrogen over
The traditional industrial process for converting methane into methanol is known to be energy and resource-intensive. Most of the catalyst systems used are based on rare and expensive transition or noble metals, making the process economically unviable for widespread use. This has been a significant barrier in the waste-to-wealth movement, which aims to convert greenhouse
Recent research led by Curtin University has provided new evidence suggesting that the emergence of fresh water on Earth occurred approximately 4 billion years ago, much earlier than the previously believed timeframe. Through the analysis of ancient crystals from the Jack Hills in Western Australia’s Mid West region, researchers have been able to push back
Methane, a potent greenhouse gas, is stored in the form of methane hydrate under the seafloor. With at least 1,800 gigatons of carbon stored in this solid form, the potential release of methane due to climate change poses a significant threat. As temperatures rise, methane hydrate can break down into methane gas and water, leading
The aviation industry is undergoing a significant transformation with the adoption of artificial intelligence (AI). While the idea of replacing pilots with AI may still be a distant future, experts believe that AI is already revolutionizing the way airlines do business. According to Julie Pozzi, the head of data science and AI at Air France-KLM,
The sunspot region AR 3664, known for its powerful X-class flares, re-emerged on May 27th as AR 3697. This region continued to show its activity by emitting multiple X-class flares, with a total of five at the time of writing. Despite the impressive display, there have been no reports of coronal mass ejections accompanying these
From non-stick frying pans to stain-resistant sofas, per- and polyfluoroalkyl substances (PFAS) have become ubiquitous in our daily lives. These “forever chemicals” have been used in a wide range of consumer and commercial products since the 1950s, thanks to their ability to repel water and oil, resist high temperatures, and act as surfactants. With around
China’s Chang’e-6 lunar probe made a historic landing on the far side of the Moon, marking a significant milestone for the country’s space program. The probe touched down in the South Pole-Aitken Basin, one of the largest impact craters in the solar system. This successful landing is the first time samples will be collected from
Being a father is often associated with joy, responsibility, and love. However, recent findings from a longitudinal, multi-ethnic US study have revealed a concerning trend – fathers tend to have poorer heart health compared to non-fathers. This study sheds light on the potential impact of fatherhood on cardiovascular health and suggests that there may be
Nvidia recently made headlines with its announcement of new products and plans to advance the field of artificial intelligence. The company’s CEO, Jensen Huang, delivered a compelling speech at the Computex tech expo in Taipei, emphasizing that “the next industrial revolution has begun”. Along with other industry giants like AMD, Intel, and Qualcomm, Nvidia is
In recent years, Japan has seen a surge in the number of tourists visiting the country, with many being drawn to the unique experience offered by high-tech toilets. These bidet toilets, known for their warm seats and precision spray technology, have become a staple in luxury bathrooms worldwide. In fact, more than 80 percent of
Metal halide perovskites have gained significant attention due to their exceptional optoelectronic properties. These materials, especially tin halide perovskites, have shown great potential in developing high-performance p-type transistors. However, the development of n-type transistors based on tin perovskites has been challenging, limiting the creation of complementary logic circuits. To address this issue, researchers have been
A recent study conducted by researchers at Johns Hopkins University suggests that one of the most significant bursts of biodiversity in Earth’s history, known as the Great Ordovician Biodiversification Event, may have been facilitated by the actions of prehistoric worms. These small creatures, which existed roughly 480 million years ago, played a vital role in
