A new Penn State study suggests that just four minutes of daily strength training can significantly improve mobility and physical function in older adults. After 12 weeks, participants showed meaningful gains in balance, leg strength, and their ability to stand up from a chair, all important factors for maintaining independence and reducing fall risk.
NASA’s Perseverance rover has shattered a historic space exploration record, traveling farther across another world than any vehicle before it. Its advanced self-driving system helped it surpass Opportunity’s 28.06-mile record in just five and a half years, a feat that previously took nearly 15. Now, Perseverance is exploring some of the oldest rocks in the solar system, searching for clues about ancient Martian environments that may once have supported life.
A decades-long mystery beneath the North Sea has finally been solved. Scientists have confirmed that the Silverpit Crater, buried 700 meters below the seabed, was created when a 160-meter-wide asteroid struck Earth roughly 43 to 46 million years ago. The violent collision blasted a towering curtain of rock and water 1.5 kilometers into the air and triggered a tsunami more than 100 meters high.
Deep inside a high-altitude Chinese cave, scientists discovered a ghostly, eyeless freshwater snail that has evolved to live entirely in darkness, marking the first recorded discovery of its kind in China. Named after a faceless mythical creature, the rare species may already be in danger, with researchers finding only three living adults.
All neutron stars have intense magnetic fields. The typical magnetic field of a neutron star is about 100,000 times stronger than the strongest magnetic fields we can create on Earth. But about 1% of neutron stars have even stronger magnetic fields. Known as magnetars, their magnetic fields can be 1,000 times stronger than a regular magnetic field. They are a likely cause of powerful transient events such as soft gamma-ray repeaters and fast radio bursts. A new study looks at how magnetars might form. The findings are published on the arXiv preprint server.
Public and private investments must address the financial barriers preventing women from benefiting fully from digital technologies and artificial intelligence as multiple global crises and aid cuts bite.
A study by DZNE finds that healthy eating is associated with slower biological aging—and that there is more than one way to eat healthily. The researchers examined ten dietary patterns considered healthy, including the Mediterranean, Nordic, and a plant-based diet, as well as the DASH diet, which is designed to help lower blood pressure. The findings are published in the journal Nature Communications.
Molecules can spontaneously organize into complex, ordered structures through a process known as self-assembly. Among these structures, soft quasicrystals display unusual patterns that do not repeat regularly like conventional crystals. However, producing such structures with a uniform orientation over large areas remains a major challenge.
Volunteer researcher Chris Hopper, JCU's adjunct professor Eric Wolanski and independent researcher Natalie K. Dowling examined the impact of saltwater and erosion on Horseshoe Bay Lagoon, a freshwater lagoon and one of the few swamps with bulkuru sedge—also known as water chestnut—on the island. The study is published in the journal Applied Sciences.
The most comprehensive data set ever collected from Earth's atmosphere during a solar radiation event has highlighted the importance of better-coordinated radiation monitoring for aviation safety, according to new research led by the University of Surrey.
