Breaking the temperature barrier in small-scale materials testing

Researchers have demonstrated a new method for testing microscopic aeronautical materials at ultra-high temperatures. By combining electron microscopy and laser heating, scientists can evaluate these materials much more quickly ...

An iron-clad asteroid

Itokawa would normally be a fairly average near-Earth asteroid—a rocky mass measuring only a few hundred metres in diameter, which orbits the sun amid countless other celestial bodies and repeatedly crosses the orbit of ...
