A novel Henry Ford Hospital study of mice aboard a Russian spaceflight may raise an intriguing question for the astronauts of tomorrow: Could traveling in space be bad for your joints? Researchers found early signs of cartilage breakdown in the mice, suggesting that the reduced biomechanical forces of spaceflight are at play on the musculoskeletal system.
In 2020, NASA and European-Russian missions will look for evidence of past life on Mars. But while volcanic, igneous rock predominates on the Red Planet, virtually the entire Earth fossil record comes from sedimentary rocks. Addressing the problem in Frontiers in Earth Science, Swedish scientists have begun compiling evidence of fossilized microbes in underexplored igneous rock environments on Earth, to help guide where to search for a Martian fossil record - and what to look for.
In only 25 years, ocean melting has caused ice thinning to spread across West Antarctica so rapidly that a quarter of its glacier ice is now affected, according to a new study.
The irregular galaxy NGC 4485 shows all the signs of having been involved in a hit-and-run accident with a bypassing galaxy. Rather than destroying the galaxy, the chance encounter is spawning a new generation of stars, and presumably planets.
A lunar lander named for the Chinese goddess of the moon may have lessened the mystery of the far side of the moon. The fourth probe of Chang'E (CE-4) was the first mission to land on the far side of the moon, and it has collected new evidence from the largest crater in the solar system, clarifying how the moon may have evolved.
The study of a new water-cycle in the Martian summertime offers clues as to why Mars is a dusty barren land.
Topping the list of Australia's major crops, wheat is grown on more than half the country's cropland and is a key export commodity. With so much riding on wheat, accurate yield forecasting is necessary to predict regional and global food security and commodity markets. A new study published in Agricultural and Forest Meteorology shows machine-learning methods can accurately predict wheat yield for the country two months before the crop matures.
A group of researchers from the University of Helsinki has found a ground breaking new method to facilitate the observation of photosynthetic dynamics in vegetation. This finding brings us one step closer to remote sensing of terrestrial carbon sinks and vegetation health.
A new analysis suggests that the moon is actively shrinking and producing moonquakes along thousands of cliffs called thrust faults spread over the moon's surface. The faults are likely the result of the moon's interior cooling and shrinking, causing the surface crust to shrivel and crack like a raisin's skin. The research, published in Nature Geoscience, combines data from NASA's Apollo and Lunar Reconnaissance Orbiter missions.
To address messy measurements of the cosmic web that connects matter in the universe, researchers at Berkeley Lab developed a way to improve the accuracy and clarity of these measurements based on the stretching of the universe's oldest light.
