Salt causes chalk cliffs to collapse

Salt plays a greater role in undermining chalk cliffs than previously thought, say scientists. Until recently, if a chalk cliff collapsed it was blamed on waves eroding its base, or the chalk weakening as it became saturated ...

Nanosuits help small creatures survive a vacuum

(Phys.org) —Scientists use scanning electron microscopes (SEMs) to study tiny structures in small organisms. SEMs can only work in a high vacuum, and exposure to such a vacuum normally causes living things to die very ...

Snap-proof space tether

(Phys.org) —Space tethers hold intriguing potential for satellite manoeuvring, attitude control and even power generation. But about half of all orbital tether tests have either failed to deploy or snapped, probably due ...
