Young physicist ‘squares the numbers’ on time travel Paradox-free time travel is theoretically possible, according to the mathematical modeling of a prodigious University of Queensland undergraduate student. Fourth-year Bachelor of Advanced Science (Honours) student Germain […]
Why there is no speed limit in the superfluid universe Physicists from Lancaster University have established why objects moving through superfluid helium-3 lack a speed limit in a continuation of earlier Lancaster research. Helium-3 is […]
Researchers develop the world’s smallest ultrasound detector Researchers at Helmholtz Zentrum München and the Technical University of Munich (TUM) have developed the world’s smallest ultrasound detector. It is based on miniaturized photonic circuits on top […]
Engineers produce a fisheye lens that’s completely flat To capture panoramic views in a single shot, photographers typically use fisheye lenses—ultra-wide-angle lenses made from multiple pieces of curved glass, which distort incoming light to produce […]
New calculation refines comparison of matter with antimatter An international collaboration of theoretical physicists—including scientists from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory (BNL) and the RIKEN-BNL Research Center (RBRC)—has published a new […]
Human white blood cells use molecular paddles to swim Human white blood cells, known as leukocytes, swim using a newly described mechanism called molecular paddling, researchers report in the September 15th issue of Biophysical Journal. This […]
