(Phys.org) —Scientists have developed an acoustic lens that produces pressure pulses that are so intense they're called "sound bullets." Although they are too high-pitched to be audible to the human ear, the sound bullets ...
(Phys.org) —Controlling the propagation of high-intensity light beams as they travel through air (or other transparent media) is a challenging task, but scientists have now shown that a relatively new type of light beam ...
(PhysOrg.com) -- On the nanoscale, things aren’t always what they seem. What first looked like a continuous plasma jet has turned out to be a train of tiny, high-velocity plasma bullets. Using a camera with an exposure ...
All cells have a lipid membrane that encircles their internal components—forming a protective barrier to control what gets in and what stays out. The proteins embedded in these membranes are essential for life; they help ...

(Phys.org)—A team of researchers working at Rice University in the U.S. has demonstrated that graphene is better able to withstand the impact of a bullet than either steel or Kevlar. In their paper published in the journal ...
(Phys.org)—Japan intends to outdo itself, rendering the sleek bullet train system that won it fame in the 1960s toward becoming so "yesterday." You can now look forward to the upcoming marvels of floating trains. The country ...
(PhysOrg.com) -- Acoustic devices are used in a range of applications such as ultrasound scanners, but their performance is limited for some uses by their inaccurate focusing and low focal power. Now a group of scientists ...
The 6 Feb. 2023 earthquakes of eastern Turkiye were the most devastating in the region for the past century. Researchers from China University of Geosciences, US Geological Survey, and Middle East Technical University were ...

A bullet is a projectile propelled by a firearm, sling, or air gun. Bullets do not normally contain explosives, but damage the intended target by impact and penetration. The word "bullet" is sometimes erroneously used to refer to ammunition generally, or to a cartridge, which is a combination of the bullet, case/shell, powder, and primer.
