Ancient hominins used fire to make stone tools

Human ancestors not only knew how to use fire, they also developed sophisticated technologies for making tools. Researchers at the Weizmann Institute of Science recently employed cutting-edge technologies of their own to ...

Visualizing cement hydration on a molecular level

The concrete world that surrounds us owes its shape and durability to chemical reactions that start when ordinary Portland cement is mixed with water. Now, MIT scientists have demonstrated a way to watch these reactions under ...

Mechanically controllable nonlinear dielectrics

Strain-sensitive barium strontium titanate (Bax-Sr1-x-TiO3) perovskite systems are widely used for their superior nonlinear dielectric behaviors. In a new report on Science Advances, D.L. Ko and a research team in materials ...

Gold 'nanoprobes' hold the key to treating killer diseases

Researchers at the University of Southampton, in collaboration with colleagues at the University of Cambridge, have developed a technique to help treat fatal diseases more effectively. Dr Sumeet Mahajan and his group at the ...

Fiber-optic probe can see molecular bonds

In "Avengers: Endgame," Tony Stark warned Scott Lang that sending him into the quantum realm and bringing him back would be a "billion-to-one cosmic fluke."
