Magnetic fields exist everywhere in the universe, from planets and stars to entire galaxies. These invisible forces influence major cosmic events and processes, such as solar storms, the movement of high-energy particles, and even the formation of galaxies. Small magnetic fields are often chaotic and turbulent, but much larger magnetic structures appear surprisingly organized. For decades, scientists have struggled to explain how the disorder in the universe creates such large-scale order. Now, researchers led by scientists at the University of Wisconsin-Madison think they may have found the missing piece of the puzzle. In a new study published in naturethe team…

NASA’s Psyche spacecraft successfully flew close to Mars by using the planet’s gravity to gain speed and change course towards the asteroid Psyche. On May 15, the spacecraft passed within 2,864 miles (4,609 kilometers) of the surface of Mars, receiving significant gravity assistance without using additional onboard fuel. This maneuver sends Psyche on a direct route to a target in the asteroid belt between Mars and Jupiter. After the flyby, engineers confirmed that the spacecraft was exactly where it needed to be by analyzing radio communications between Psyche and NASA’s Deep Space Network (DSN), the agency’s worldwide communications system for…

When news of the Ebola outbreak in the Democratic Republic of the Congo broke more than a week ago, Jason Kindrachuk was feeling optimistic, knowing the capabilities of the local responders and medical workers he’s worked with on the ground.But Canadian microbiologists say their optimism about containing the outbreak has waned in recent days. There are now more than 1,000 suspected cases and hundreds of deaths, mainly across northeastern Congo, with seven deaths in neighboring Uganda. Scientists suspect the true number of cases may be much higher, as the infection likely spread for weeks or more before global health authorities…

Eating more legume and soy foods may lower your risk of developing high blood pressure, according to a large new analysis published in an open access journal. BMJ Nutrition Prevention and Health. Researchers have found that people who regularly consume foods such as beans, lentils, chickpeas, tofu, edamame, and soy milk are less likely to develop high blood pressure. The most effective results were found when consuming about 170 grams of legumes per day and 60 to 80 grams of soybean foods per day. Legumes include foods such as peas, lentils, chickpeas, and beans. Soy foods include tofu, soy milk,…

As tropical cities warm, this review reveals why parks, shade, heat advisories and smarter public messaging need to work in tandem to protect the benefits of outdoor recreation without exposing vulnerable communities to dangerously humid heat. Review: The future of nature-based recreation in warming tropical cities. Image credit: taka1022 / Shutterstock Recent review articles published in magazines npj urban sustainability We reviewed the evidence on outdoor recreation and humid heat stress in tropical cities. Cities around the world are turning to urban greening to harness the benefits of nature. Nature-based recreation in cities can promote physical and mental health, increase…

Researchers at the University of Southern California have identified an experimental compound that may help reduce brain inflammation associated with Alzheimer’s disease. The research results were published in the journal Nature npj drug discoveryfocuses on an enzyme called calcium-dependent phospholipase A2 (cPLA2), which appears to play an important role in inflammation in the brain. The USC team linked elevated cPLA2 activity to Alzheimer’s risk while studying people with the APOE4 gene, the strongest known genetic risk factor for Alzheimer’s disease. Researchers found that while many APOE4 carriers do not develop Alzheimer’s disease, those with high cPLA2 activity are more likely…

Snakes are endangered in many places around the world. Diseases are often caused by parasites and fungi and are thought to be one of the key factors, along with habitat destruction. Prominent among the fungal diseases is ophidimycosis (also known as snake mycosis), which is caused by fungi. Ophidiomyces Ofhidicola (oh). In the 20 years since its discovery, it has been found in many snake species. To obtain an evidence-based overview of snake health, researchers in the southeastern United States investigated seven pathogens in wild native snakes and compared their prevalence across time, space, and among snake species. The result…

The cortex, the outer region of the brain, contains a specific layer of different cells, neurons, that are ordered similarly in all mammals, from the tiny mouse brain to the giant elephant brain. However, the proportions of different cell layers vary widely between species, and little is known about how and why this change occurs. Now, after intense research into the development of brain cells, researchers at Osaka University suggest that these differences are related to the timing of specific signals in the brain during early development. These findings show that EMBO Journal.The researchers began their investigation by focusing specifically…

Scientists at Singapore’s Nanyang Technological University (NTU Singapore) have developed a small, seed-sized robot that can move over soft, uneven surfaces and perform five surgical functions wirelessly. This has paved the way for the development of robots to make surgeries and treatments more precise. The small robot, just 4.4 mm long, is controlled by a weak magnetic field and can move, cut biological tissue, release drugs, grab and store tissue samples, or remotely generate heat at any time. Toggling between these features takes less than a second.The research, led by Associate Professor Lum Guo Zhan from NTU’s School of Mechanical…

Analysis of global race records reveals how gender, age, nationality and distance combine to shape endurance running, from 5km speed to marathon dominance. Study: Associations between nationality, gender, age and running performance in endurance runners: An empirical analysis of global long-distance race data from 1999 to 2024. Image credit: kovop / Shutterstock In a recent study published in the journal Scientific Reports, a group of researchers investigated how nationality, gender, and age were associated with running performance in 5km, 10km, half-marathon, and marathon events around the world from 1999 to 2024. background Why do runners from Kenya and Ethiopia dominate…
