Could Martian atmospheric samples teach us more about the red planet than surface samples?
NASA is actively working to return surface samples from Mars in the next few years, which they hope will help us better understand whether ancient life once existed on the red planet's surface billions of years ago. But what about atmospheric samples.....»»
Human "molecular map" contributes to the understanding of disease mechanisms
Scientists at Weill Cornell Medicine in Qatar (WCM-Q) have created an intricate molecular map of the human body and its complex physiological processes based on the analysis of thousands of molecules in blood, urine and saliva samples from 391 volunt.....»»
9 phenomena NASA astronauts will encounter at Moon"s south pole

Astronomers track bubbles on star"s surface
For the first time, astronomers have captured images of a star other than the sun in enough detail to track the motion of bubbling gas on its surface. The images of the star, R Doradus, were obtained with the Atacama Large Millimeter/submillimeter Ar.....»»
How the oceans" most abundant bacteria impact global nutrient flows
If you were to collect all the organisms from the ocean surface down to 200 meters, you'd find that SAR11 bacteria, though invisible to the naked eye, would make up a fifth of the total biomass. These bacteria, also known as Pelagibacterales, have ev.....»»

Cloud atlas of Mars showcases array of atmospheric phenomena
Cloud enthusiasts have a new tool to investigate striking formations in the skies above the red planet. A browsable database of 20-years-worth of images of clouds and storms, created by the German Aerospace Centre (DLR) in Berlin, is helping scientis.....»»
Bringing electricity to the smallest villages is not likely to reduce poverty
Nearly 800 million people in the world lack access to commercial electricity. It is easy to assume that connecting them to the grid will reduce poverty and improve lives. In fact, expanding energy infrastructure to everyone on the planet by 2030 is o.....»»
Shallow waters make the best carbon sinks, researchers find
Marine phytoplankton take up atmospheric carbon and carry it to the seafloor when they die and sink (a process known as organic carbon sedimentation). This biological carbon pump is a powerful part of Earth's carbon cycle, yet scientists don't have a.....»»
Researchers find live fungi, bacteria and viruses high in the Earth"s atmosphere
A team of climate, health and atmospheric specialists in Spain and Japan has found abundant live fungi, bacteria and viruses high in the Earth's atmosphere. In their study published in the Proceedings of the National Academy of Sciences, the group co.....»»
With AI, extreme microbe reveals how life"s building blocks adapt to high pressure
An assist from a Google Artificial Intelligence tool has helped scientists discover how the proteins of a heat-loving microbe respond to the crushing conditions of the planet's deepest ocean trenches, offering new insights into how these building blo.....»»
Formation of super-Earths proven limited near metal-poor stars
In a new study, astronomers report novel evidence regarding the limits of planet formation, finding that after a certain point, planets larger than Earth have difficulty forming near low-metallicity stars......»»
Could comets have delivered the building blocks of life to ocean worlds like Europa, Enceladus and Titan?
Throughout Earth's history, the planet's surface has been regularly impacted by comets, meteors, and the occasional large asteroid. While these events were often destructive, sometimes to the point of triggering a mass extinction, they may have also.....»»
Did dwarf planet Ceres originate in the asteroid belt?
The dwarf planet Ceres has a diameter of almost 1,000 kilometers and is located in the asteroid belt. In the television series "The Expanse," Ceres gained new fame as the main base of the so-called 'belters': in this series, which is based on real ph.....»»
Greenpeace sounds alarm on microplastics ingested by Hong Kong wildlife
Microplastic particles turned up in the vast majority of waste samples taken from Hong Kong wildlife in a Greenpeace study, the group said Monday, suggesting that animals still ingest plastics even if they are not feeding in urban areas......»»
The moon had surprisingly recent volcanic activity, samples from Chinese space mission confirm
Volcanoes were erupting on the moon as recently as 120 million years ago, evidence collected by a Chinese spacecraft suggests. Until the last few years, scientists had thought volcanic activity ended on the moon around 2 billion years ago......»»
Uncovering microplastic dynamics and patterns in coastal habitats
Microplastics have raised concerns among scientists and the public in recent years due to their widespread presence and associated health risks. They have been found in every corner of the planet, from mountain peaks to the deep sea, and in the diets.....»»
With NASA’s plan faltering, China knows it can be first with Mars sample return
