With two-thirds of children in the U.S. failing to meet national physical activity guidelines, kinesiologistshave been looking at the impact of the family dog on the exercise habits of kids. Could having a canine best friend get kids on their feet and help bring them more in line with the minimum recommendation of 60 minutes of moderate to vigorous physical activity every day?

A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organized magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*). Seen in polarized light for the first time, this new view of the monster lurking at the heart of the Milky Way Galaxy has revealed a magnetic field structure strikingly similar to that of the black hole at the center...

Floods affect more people worldwide than any other natural hazard, causing enormous damage that is expected to increase in a warming world. However, people and decision-makers in vulnerable regions are often unwilling to prepare for exceptionally severe events because they are difficult to imagine and beyond their experience. Read more ›

What makes us human? According to neurobiologists it is our neocortex. This outer layer of the brain is rich in neurons and lets us do abstract thinking, create art, and speak complex languages. An international team has identified a new factor that might have contributed to neocortex expansion in humans. Read more ›

Quantum simulators are quantum systems that can be controlled exceptionally well. They can be used to indirectly learn something about other quantum systems, which cannot be experimented on so easily. Therefore, quantum simulators play an important role in unraveling the big questions of quantum physics. However, they are limited by temperature: They only work well, when they are extremely cold. Scientists have now developed a method to cool quantum simulators... Read more ›

Conditions that usually accompany the kind of intense hot and cold weather that strains power grids may also provide greater opportunities to capture solar and wind energy. A study found that widespread, extreme temperature events are often accompanied by greater solar radiation and higher wind speeds that could be captured by solar panels and wind turbines. The research, which looked at extensive heat and cold waves across the six interconnected... Read more ›

Engineers have uncovered an unexpected pattern in how neural networks -- the systems leading today's AI revolution -- learn, suggesting an answer to one of the most important unanswered questions in AI: why these methods work so well. The result not only illuminates the inner workings of neural networks, but gestures toward the possibility of developing hyper-efficient algorithms that could classify images in a fraction of the time, at a...

In a remarkable discovery, whole milk powder manufactured in New Zealand in 1907 and transported to Antarctica with explorers seeking the South Pole was unveiled after more than a century. The find has allowed dairy researchers to answer the question: Is the milk we enjoy today different from the milk consumed in previous generations? Now, a new comparative study has peered back in time to demonstrate that -- despite advancements... Read more ›

Engineers have developed a novel method for manufacturing CAR T cells, one that takes just 24 hours and requires only one step, thanks to the use of lipid nanoparticles (LNPs), the potent delivery vehicles that played a critical role in the Moderna and Pfizer-BioNTech COVID-19 vaccines. Read more ›

The Antarctic Circumpolar Current plays an important part in global overturning circulation, the exchange of heat and CO2 between the ocean and atmosphere, and the stability of Antarctica's ice sheets. An international research team has now used sediments taken from the South Pacific to reconstruct the flow speed in the last 5.3 million years. Their data show that during glacial periods, the current slowed; during interglacials, it accelerated. Consequently, if... Read more ›
