What is the weight of a proton? Scientists from Germany and Japan have made an important step toward better understanding this fundamental constant. By means of precision measurements on a single proton, they were able … Read more
In 1928, physicist Paul Dirac made the stunning prediction that every fundamental particle in the universe has an antiparticle – its identical twin but with opposite charge. When particle and antiparticle met they would be … Read more
We may not be able to time a live Tyrannosaurus rex in the 100-yard dash, but scientists say they now have a good sense of the maximum speed for many of the world’s largest animals, … Read more
Nuclear astrophysicists successfully created the first low-energy particle accelerator beam deep underground in the United States, bringing them one step closer to understanding how the elements of our universe are built. Through the project, called … Read more
You won’t find ice cubes like this in your freezer. An international team of scientists has set a new record for creating ice crystals that have a near-perfect cubic arrangement of water molecules—a form of … Read more
Producing biofuels like ethanol from plant materials requires various enzymes to break down the cellulosic fibers. Neutrons have identified the specifics of an enzyme-catalyzed reaction that could significantly reduce the total amount of enzymes used, … Read more
A new algorithm developed by Stanford computer scientists can sift through hours of heart rhythm data generated by some wearable monitors to find sometimes life-threatening irregular heartbeats, called arrhythmias. The algorithm, detailed in an arXiv … Read more
In a recent publication, Aalto University researchers show that in a transparent medium each photon is accompanied by an atomic mass density wave. The optical force of the photon sets the medium atoms in motion … Read more
Researchers at the University of Melbourne have demonstrated a way to detect nuclear spins in molecules non-invasively, providing a new tool for biotechnology and materials science. Important research in medicine and biology relies on nuclear … Read more
Using a state-of-the-art device for measuring mass, researchers at the National Institute of Standards and Technology (NIST) have made their most precise determination yet of Planck’s constant, an important value in science that will help … Read more
