A research team has found asteroid impacts on the Moon millions of years ago coincided precisely with some of the largest meteorite impacts on Earth, such as the one that wiped out the dinosaurs.

An international team of researchers has revealed new evidence for the possible existence of liquid water beneath the south polar ice cap of Mars.

Scientists have created the first pan-cancer mycobiome atlas -- a survey of 35 types of cancer and their associated fungi.

After 10 months flying in space, NASA's Double Asteroid Redirection Test (DART) -- the world's first planetary defense technology demonstration -- successfully impacted its asteroid target on Monday, the agency's first attempt to move an asteroid in space.

A recent study in Japan has found that reared ambrosia beetles, Euwallacea interjectus, can have symbiotic fungi different to those found in the wild. These findings suggest biocontrol implications for pest beetles that damage valuable crop trees such as fig trees.

Astronomers believe bright reflections beneath the surface of Mars' South Pole are not necessarily evidence of liquid water, but instead geological layers.

Researchers have demonstrated that chemical compounds containing special metals are highly effective in fighting dangerous fungal infections. These results could be used to develop innovative drugs which are effective against resistant bacteria and fungi.

In December 2020, a small landing capsule brought rock particles from the asteroid Ryugu to Earth -- material from the beginnings of our solar system. The Japanese space probe Hayabusa 2 had collected the samples. Geoscientists have now discovered areas with a massive accumulation of rare earths and unexpected structures.

Researchers investigated how the process of human body decomposition affected microbial life of the surrounding soil microbiome. One factor that may play an important role is body mass index (BMI), they report.

NASA's James Webb Space Telescope shows off its capabilities closer to home with its first image of Neptune. Not only has Webb captured the clearest view of this distant planet's rings in more than 30 years, but its cameras reveal the ice giant in a whole new light.

An international team of researchers with NASA's InSight mission located four new craters created by impacts on the surface of Mars. Using data from a seismometer and visuals acquired from the Mars Reconnaissance Orbiter, the team successfully calculated and confirmed the impact locations. Researchers have now captured the dynamics of an impact on Mars.

A new study links an amphibian die-off in Costa Rica and Panama with a spike in malaria cases. The study demonstrates the importance of biodiversity to human health.

Fungal pathogens have a major global impact upon human health -- they are often difficult to diagnose and treat, and there is an urgent need for better diagnostics and more effective antifungal treatments. Using newly developed imaging technologies, researchers have now revealed how Candida albicans, a common fungus, evades immune responses. According to the researchers this involves an 'alien-like' shape shifting that allows the fungus to break out of immune cells.

The search for extraterrestrial life just got more interesting as a team of scientists has discovered new evidence for a key building block for life in the subsurface ocean of Saturn's moon Enceladus. New modeling indicates that Enceladus's ocean should be relatively rich in dissolved phosphorus, an essential ingredient for life.

It's been known for decades that astronauts' immune systems become suppressed in space, leaving them vulnerable to disease, but the exact mechanisms of immune dysfunction have remained a mystery -- now a Cornell undergraduate has found a potential solution.

Though Mars is a frozen desert today, scientists have shown that Mars contains evidence of ancient lakes that existed billions of years ago, which could contain evidence for ancient life and climate conditions on the red planet. Through a meta-analysis of years of satellite data that shows evidence for lakes on Mars, a geologist has proposed that scientists might have dramatically underestimated the number of ancient Martian lakes that once existed.

NASA's Perseverance rover is well into its second science campaign, collecting rock-core samples from features within an area long considered by scientists to be a top prospect for finding signs of ancient microbial life on Mars.

Researchers have identified a new reason to protect mangrove forests: they've been quietly keeping carbon out of Earth's atmosphere for the past 5,000 years.

Scientists propose a lost moon of Saturn, which they call Chrysalis, pulled on the planet until it ripped apart, forming rings and contributing to Saturn's tilt.

Researchers present the most precise test yet of the weak equivalence principle, a key component of the theory of general relativity. The report describes the final results from the MICROSCOPE mission, which tested the principle by measuring accelerations of free-falling objects in a satellite orbiting Earth.
