More than 3 billion years ago, Mars intermittently had liquid water on its surface. After the planet lost much of its atmosphere, however, surface water could no longer persist. The fate of Mars's water—whether it was buried as ice, confined in deep aquifers, incorporated into minerals or dissipated into space—remains an area of ongoing research, one of particular interest to LASP Senior Research Scientist Bruce Jakosky, former principal investigator of the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission.

Taking children to the supermarket isn't always top of the list for parents, but the family grocery shop can have a positive influence on children's future buying habits.

CubeSats have a lot of advantages. They are small, inexpensive, and easily reproducible. But those advantages also come with significant disadvantages—they have trouble linking into broader constellations that allow them to be more effective at their observational or communication tasks. A team from the University of Albany thinks they might have solved that problem by using a customized calibration algorithm to ensure the right CubeSats link up together.

A Jilin University team has reported a novel strategy using pressure engineering to identify the organic–inorganic interaction sites in non-hydrogen-bonded hybrid metal perovskites. This approach offers valuable guidance for designing materials with targeted optical properties and provides new insights into the photophysical mechanisms in hybrid perovskites.

In the study of why and how animals look the way they do, color is king—at least, the range of color humans can see. A University of Michigan study has examined a color range that humans can't see and often ignore: color in the ultraviolet range. Examining snakes, the researchers categorized how the animals used patterns of UV color and tested for factors that promote the evolution of UV color in snakes.

Geological resources such as critical metals and minerals, essential for the diffusion of technologies such as renewable energy and energy storage towards a decarbonized society, are indispensable for supporting modern life in the form of various products and services. Their demand is expected to increase in the coming years, owing to the global population as well as economic growth.

A study conducted by researchers at ESPOL has developed genetically improved bean varieties that are capable of withstanding water scarcity conditions. This discovery is crucial for developing more efficient agricultural strategies. Growing drought-resistant bean varieties will not only ensure stable production but also reduce dependence on excessive irrigation. This promotes more sustainable agriculture.

Researchers have been reporting a disturbing rise in sexist, misogynist behavior from students in school classrooms.

When we observe distant celestial objects, there is a possible catch: Is that star I am observing really as reddish as it appears? Or does the star merely look reddish, since its light has had to travel through a cloud of cosmic dust to reach our telescope?

Scientists warned on Thursday that the long-term health of Inuit hunters in eastern Greenland was under threat, due to so-called "forever chemicals" in the atmosphere and their diet of polar bear and seal meat.
