Good health depends on a healthy diet and sufficient exercise and sleep. There are clear associations among these components; for example, good nutrition provides energy for exercise, and many people report that getting enough exercise is important to their ability to get enough sleep. So how might nutrition affect sleep?

A new study looks at the connection between fruit and vegetable intake and sleep duration. The research, by a team from Finland’s University of Helsinki, National Institute for Health and Welfare, and Turku University of Applied Sciences, is published in Frontiers in Nutrition.

Why sleep is important and how it works Sleep gives our bodies the chance to rest and recover from wakeful activity. Our hearts, blood vessels, muscles, cells, immune systems, cognitive abilities, and memory-making abilities depend on regular, healthy sleep for optimal functioning, and a 2019 study suggests that sleep is important for repairing DNA damage that occurs during wakefulness.

(NewsNation) — Researchers have found a significant source of geothermal energy underneath the U.S.-Mexico border along the Rio Grande, which could lead to promising clean energy development in the rural region.

The findings came after a monthslong study conducted by the Bureau of Economic Geology at the University of Texas at Austin, which discovered that the region of Presidio County in Texas, which shares a border with Mexico, has the conditions necessary for geothermal development.

“There’s a thin, 10-to 15-mile-wide region that runs parallel or along the Rio Grande that has very high heat by at least by most standards, and even in the interior part of the county, which is probably two-thirds of the county,” Ken Wisian, head of the research team, told NewsNation.

A 3,300-year-old ship has been discovered at the bottom of the Mediterranean Sea, making it one of the oldest shipwrecks ever discovered and rewriting our understanding of sailing in the ancient world, according to the Israel Antiquities Authority.

The vessel is estimated to be from the 13th or 14th century BCE, the authority said in a statement. It was discovered 90 kilometers (around 56 miles) from the shore, in waters 1.8 kilometers (1.1 miles) deep, with hundreds of intact jars still on board, the statement added.

The ship’s remains were found during an environmental survey of the seabed by London-based natural gas production company Energean, according to Karnit Bahartan, the head of the company’s environment team.

A new study by Brown University researchers may help redefine how scientists map the surface of the Moon, making the process more streamlined and precise than ever before.

Published in the Planetary Science Journal, the research by Brown scholars Benjamin Boatwright and James Head describes enhancements to a mapping technique called shape-from-shading. The technique is used to create detailed models of lunar terrain, outlining craters, ridges, slopes and other surface hazards. By analyzing the way light hits different surfaces of the Moon, it allows researchers to estimate the three-dimensional shape of an object or surface from composites of two-dimensional images.

Accurate maps can help lunar mission planners to identify safe landing spots and areas of scientific interest, making mission operations smoother and more successful.

Join my mailing list https://briankeating.com/list to win a real 4 billion year old meteorite! All.edu emails in the USA 🇺🇸 will WIN!Is the universe twice as old as we thought?Current estimates suggest that the Big Bang occurred 13.8 billion years ago. But today, we’re joined by Rajendra Gupta, a luminary in the field of cosmology who claims that the universe is actually 26.7 billion years old. I’ve invited him on the show so he can make a case for his claims!Professor Gupta is a theoretical physicist currently teaching astrophysics to senior undergraduate and graduate students at the University of Ottawa. His research focuses on astrophysics, cosmology, general relativity, the dynamics of the universe under evolutionary physical constants beyond the standard model, CMB, JWST, BAO, Big Bang nucleosynthesis, the large-scale structure and formation of galaxies, dark matter, and dark energy. To say I am thrilled to have him on the show for the second time would be an understatement. So, without further ado, let’s jump right in! Key Takeaways:

While seeking research internships last year, University of Washington graduate student Kate Glazko noticed recruiters posting online that they’d used OpenAI’s ChatGPT and other artificial intelligence tools to summarize resumes and rank candidates. Automated screening has been commonplace in hiring for decades. Yet Glazko, a doctoral student in the UW’s Paul G. Allen School of Computer Science & Engineering, studies how generative AI can replicate and amplify real-world biases—such as those against disabled people. How might such a system, she wondered, rank resumes that implied someone had a disability?
