Study: Fruits, vegetables protect against inflammatory bowel diseases
July 9 (UPI) -- A healthy plant-based diet might protect people from inflammatory bowel diseases, a new study says.
People noshing healthy plant-based foods had a 14% lower risk of Crohn's disease and an 8% lower risk of ulcerative colitis, researchers found.
On the other hand, an unhealthy diet containing more animal fats and vegetable oils was associated with a 15% increased risk of Crohn's disease, results show.
"Our research indicates that a healthy plant-based diet may protect against inflammatory bowel disease, with its anti-inflammatory properties playing a key role," senior researcher Dr. Zhe Shen of the Zhejiang University School of Medicine in China said in a news release.
For the study, researchers tracked more than 143,000 people participating in the UK Biobank, a large-scale health research project among residents of the United Kingdom. As part of the project, patients filled out diet questionnaires.
During an average 14.5 years of follow-up, more than 1,000 people developed inflammatory bowel disease, researchers found.
Researchers graded participants' diet based on their intake of healthy plant foods, unhealthy plant foods, and animal products.
Analysis showed that higher intake of fruits and vegetables accounted for part of the lower risk for Crohn's disease, researchers said.
Blood tests from participants indicate that the anti-inflammatory properties of plant-based foods might explain this protection, researchers said.
"These findings underscore the beneficial association between healthy plant-based diets and reduced risk of ulcerative colitis and Crohn's disease," researchers concluded. "They provide important insights for the development of dietary guidelines aimed at preventing IBD."
The new study appears in the journal Molecular Nutrition & Food Research.

NASA's X-59 moves under its own power
NASA determined that its experimental X-59 aircraft can move under its own power following a test on July 10, 2025. The success of the test could lead to quieter supersonic aircrafts. Photo by Carla Thomas/NASA July 22 (UPI) -- NASA's quest for a quieter supersonic jet passed an early test after its X-59 aircraft was able to taxi at low speed at a manufacturing plant in California. The space agency on Tuesday announced the latest milestone for NASA's X-59 that is part of its Quesst mission to test the possibility of a supersonic aircraft with more muted sonic booms that will allow less noisy flights over populated areas. The X-59 was able to move under its own power during the test that took place last week, taxiing across the runway at the U.S. Air Force Plant 42 in Palmdale, Calif. As the aircraft taxied, engineers and flight crews observed the X-59 to evaluate its steering, braking and other important functions. The test was one of the final hurdles for the X-59 before its first flight, according to the agency. NASA engineers began test-firing the single-engine experimental aircraft at a Lockheed Martin facility last fall to see if its systems are functional. NASA plans to fly the X-59 between residential areas in 2026 and ask residents about the noise it produces while exceeding the speed of sound. If the X-59 works as intended it will produce a soft thud instead of the loud booms associated with sonic aircrafts. The aircraft has no windshield because its pilot can't see over it, as well as delta-shaped wings with a span of 29.5 feet and has a maximum takeoff weight of 32,300 pounds -- lighter than many commercial planes. Following the successful test, NASA engineers will gradually increase the X-59's taxing speed stopping short of where it would take off, according to the agency. Data from the X-59 will be shared with U.S. and international regulators to develop new regulations on noise threshold for commercial supersonic land flights.

Earth will spin faster marking 2nd shortest day in history
July 22 (UPI) -- Scientists predicted that Tuesday will be a fraction of a second shorter than the average day as the Earth's rotation is moving faster. The international Earth Rotation and Reference System Service expects that Tuesday will be just 1.34 milliseconds shorter than the standard 24 hours. "We've known about the rotation of the Earth being variable for about a hundred years," said the former Director of Time at the United States Naval Observatory Dennis McCarthy. "This is just one of those little variations that comes along." The speed of the Earth's rotation isn't fixed. A 2023 study showed a day was approximately 19 hours in Earth's early history. July 5, 2024, was the shortest day ever, 1.65 milliseconds shorter than the usual 86,400 seconds, said MIT geophysicist Thomas Herring. Scientists predicted that Aug. 5 could be the next day we will see a quicker rotation, 1.25 milliseconds shorter than usual. "The cause of this acceleration is not explained," a leading authority on Earth's rotation at Moscow State University, Leonid Zotov, said. "Most scientists believe that it is something inside the Earth. Ocean and atmospheric models don't explain this huge acceleration." Solve the daily Crossword

Early smartphone access harms developing minds, study warns
Early exposure to toxic social media explains much of the link between young smartphone access and poorer mental health, researchers said. Other contributing factors may include cyberbullying, disrupted sleep and poor family relationships. Photo by Andrea Piacquadio/ Pexels July 22 (UPI) -- Care about your kid's well being? Then best not give them a smartphone until they're a full-fledged teenager, a major new study says. Kids given a smartphone when they were younger than 13 tend to have poorer mental health and well-being, researchers report in the Journal of Human Development and Capabilities. Specifically, people between 18 and 24 who got their first smartphone at 12 or younger had higher odds of suicidal thoughts, aggression, detachment from reality, poorer emotional regulation and low self-worth, researchers report. Early exposure to toxic social media explains much of the link between young smartphone access and poorer mental health, researchers said. Other contributing factors may include cyberbullying, disrupted sleep and poor family relationships. "Our data indicate that early smartphone ownership- and the social media access it often brings - is linked with a profound shift in mind health and wellbeing in early adulthood," says lead researcher Tara Thiagarajan, chief scientist of Sapien Labs, said in a news release. "I was initially surprised by how strong the results are," she said. "However, when you give it due consideration, it does begin to make sense that the younger developing mind is more compromised by the online environment given their vulnerability and lack of worldly experience." For the study, researchers analyzed data from more than 100,000 young adults around the world as part of the Global Mind Project, an ongoing research effort aimed at assessing the effects of modern society on mental health. Each of the participants filled out a questionnaire to help determine their Mind Health Quotient (MHQ) - a measurement of their social, emotional, cognitive and physical well-being. The team focused on members of Generation Z born between 1997 and 2012 who were the first to grow up with smartphones and social media from early childhood. Results show that young adults who got their first smartphone before becoming teens had lower MHQ scores than those who got a phone later. In addition, the younger a person got their first smartphone, the worse their mental health and overall well-being, researchers said. For example, about half (48%) of girls who got a smartphone at age 5 or 6 report suicidal thoughts, compared with 28% who got a smartphone at 13, the study says. Girls who got smartphones at a young age were more likely to have diminished self-image, self-worth and confidence, as well as less emotional resilience, researchers found. Meanwhile, boys were more likely to have lower stability, self-worth and empathy. Looking into potential causes, researchers found that early access to social media explains about 40% of the link between earlier smartphone ownership and poorer mental health in young adulthood. The results bolster growing concerns regarding how AI-driven social media algorithms amplify harmful content and encourage children to compare their lives to those of apparently happier and better-off influencers, researchers argue. Poor family relationships (13%), disrupted sleep (12%) and cyberbullying (10%) also contributed to the link, the study says. "Based on these findings, and with the age of first smartphones now well under age 13 across the world, we urge policymakers to adopt a precautionary approach, similar to regulations on alcohol and tobacco, by restricting smartphone access for under 13s, mandating digital literacy education and enforcing corporate accountability," Thiagarajan said. Several countries have already banned or restricted cell phone use in schools, including France, the Netherlands, Italy and New Zealand, researchers noted. In the U.S., Alabama, Arkansas, Nebraska, New York, North Carolina, North Dakota, Oklahoma and West Virginia have passed legislation requiring schools to limit or ban smartphones, researchers added. "Our evidence suggests childhood smartphone ownership, an early gateway into AI-powered digital environments, is profoundly diminishing mind health and well-being in adulthood with deep consequences for individual agency and societal flourishing," Thiagarajan said. "That said, I think it is also important to point out that smartphones and social media are not the only assault to mental health and crisis facing younger adults," she said. "It explains some of the overall decline but not all of it." The study can't draw a direct cause-and-effect link between early smartphone access and poorer mental health as a young adult, researchers noted. More research is needed to confirm this link and explore its causes. "Now, while more research is needed to unravel the causal mechanisms, waiting for irrefutable proof in the face of these population-level findings unfortunately risks missing the window for timely, preventative action," Thiagarajan said.
