Beneath the moon’s cratered surface lie networks of lava tubes and deep pits, natural caves that could shelter future lunar bases from cosmic radiation and wild temperature swings. These underground structures represent some of the most scientifically valuable areas in the solar system, but they come with the very real challenge of simply getting there.

The entrances to these caves feature steep, rugged terrain with rocks and loose regolith. Small rovers, preferred for lunar exploration because you can deploy many of them to reduce mission risk, face an inherent limitation. Their compact wheels simply can’t climb over obstacles much larger than the wheel diameter itself...

Large Hadron Collider finally explains how fragile matter forms

LHC Explains How Fragile Matter Forms
Physicists have discovered that fragile atomic nuclei at CERN aren’t surviving extreme heat—they’re forming later, after things cool down. This breakthrough explains most observed deuterons and could help decode cosmic-ray signals and dark matter clues. Credit: AI/ScienceDaily.com

In collisions at CERN’s Large Hadron Collider, hotter than the Sun’s core by a staggering margin, scientists have finally solved a long-standing mystery: how delicate particles like deuterons and their antimatter twins can exist at all. Instead of forming in the initial chaos, these fragile nuclei are born later, when the fireball cools, from the decay of ultra-short-lived, high-energy particles...

NASA Rover Detects Electric Sparks in Mars Dust Devils, Storms

Perseverance confirmed a long-suspected phenomenon in which electrical discharges and their associated shock waves can be born within Red Planet mini-twisters.

NASA’s Perseverance Mars rover has recorded the sounds of electrical discharges —sparks — and mini-sonic booms in dust devils on Mars. Long theorized, the phenomenon has now been confirmed through audio and electromagnetic recordings captured by the rover’s SuperCam microphone. The discovery, published Nov. 26 in the journal Nature, has implications for Martian atmospheric chemistry, climate, and habitability, and could help inform the design of future robotic and human missions to Mars.

A frequent occurrence on the Red Planet, dust devils form from rising and rotating columns of warm air...

Naturally occurring molecule shown to restore memory function in Alzheimer’s models

An electrophysiology set-up used for studying memory-related electrical signals over long periods of time. 

Singapore has one of the highest life expectancies in the world, yet many individuals spend almost a decade in poor health toward the end of life. Scientists from the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine) are working to understand how aging itself can be modified to prevent age-related diseases, including Alzheimer’s disease.

A new study led by Professor Brian K Kennedy, Department of Biochemistry, Chair of the Healthy Longevity Translational Research Program (TRP), NUS Medicine, has discovered that calcium alpha-ketoglutarate (CaAKG), a safe, naturally occurring metabolite commonly studied for healthy aging, can restore key memory...
