Earth's nearest neighboring body in the solar system is its moon, yet to date, humans have physically explored just 5% of its surface. It wasn't until 2023—building on Apollo-era data and more ...
Dehydration leads to the blood becoming more concentrated and this can be measured using serum osmolality. Research in humans has shown that saliva conductivity is correlated with serum osmolality.
Scientists have now created a material that overcomes this barrier. Their work, published in Advanced Materials ("Monolayer Magnetic Metal with Scalable Conductivity"), describes a compound called ...
