A team of researchers with Tel Aviv University has found that at least one kind of bat (the Bodenheimer's pipistrelle) is able to zoom in on information it receives from its biosonar, by adjusting the degree to which it stretches ...
When a crystal lattice is excited by a laser pulse, waves of jostling atoms can travel through the material at close to one sixth the speed of light, or approximately 28,000 miles/second. Scientists now have a new tool to ...
