Study lays groundwork for classifying lunar soil‎

As we move closer to supporting a sustainable human presence on the moon, researchers are investigating how its soils can provide valuable resources and even grow food. An article in the Soil Science Society of America Journal proposes a classification framework to help scientists better understand lunar soils. This emerging science of "planetary pedology," the study and classification of soils beyond Earth, could help future missions select the best sites for construction, resource extraction and potential cultivation, thereby supporting long-term, sustainable human settlement on the moon.

Pluto's hazy atmosphere may be collapsing as it moves farther from the sun‎

Pluto is on an icy march away from the sun. In 2114, it will turn back, but until then, its elliptical orbit will carry it to colder and darker parts of the outer solar system. This is Pluto's first time entering the outer solar system since its 1930 discovery, and along this journey, its atmosphere could slowly freeze out.

Scientists watch, molecule by molecule, as cell helpers rescue problem proteins‎

University of Wollongong (UOW) scientists have uncovered, for the first time, exactly how two of the cell's "helper" proteins operate as a rescue crew for misfolded proteins, a discovery that sheds new light on the molecular breakdown that underpins neurodegenerative diseases.

AI translators are getting more fluent—but communication is never just a matter of words‎

Speak into a phone and an app can render your words in another language in seconds. AI-powered speech translation can be fast, convenient and fluent. But fluency does not guarantee that people will understand one another.

How the brain helps protect fertility from heat-induced damage‎

As global temperatures continue to rise, scientists are racing to understand why heat so profoundly threatens fertility across the animal kingdom. A new study from the Hebrew University of Jerusalem and collaborators has uncovered a surprising answer: The brain itself may help decide whether reproductive cells can withstand environmental stress.

Key principle to boost efficiency of artificial photosynthesis and next-generation semiconductors‎

A research team led by Taeyeon Kim, a professor in the Department of Chemistry at Sungkyunkwan University, in collaboration with a team from Yonsei University, has identified a new principle that controls charge separation, a phenomenon that plays a central role in both plants' generation of electrical energy (photosynthesis) and next-generation molecular semiconductor devices.

Over 100 South American lakes could become climate-change early-warning observatories‎

More than 100 shallow lakes stretching over 1,000 kilometers (620 miles) along the Atlantic coast of southern Brazil and Uruguay could become one of the world's most important natural laboratories for understanding how climate change and human activities reshape freshwater ecosystems.

Watching comedy helps people detect faint smiles, a new study shows‎

In everyday life, the ability to read facial expressions plays a vital role in social communication, as it reveals a speaker's underlying emotions, intentions and psychological state. More importantly, accurately recognizing subtle signs of positive emotions can help build trust, enhance cooperation and strengthen relationships.

Rising seas are inundating US coastal wetlands, putting many on track to become open water‎

Along the three coasts of the contiguous United States, a silent race unfolds. Fueled by climate change, sea levels rise faster than at any time in recent geologic history. Meanwhile, coastal wetlands cling to a slim lead, lifted on newly accumulated sediments or moving inland as encroaching tides nip at their heels.
