University of Chicago scientists have solved a 20-year-old puzzle in particle physics using data from an experiment conducted for an entirely different purpose.
Physicists had long known that something was amiss regarding their understanding of how some quarks interact in the beta decay of particles, a common form of radioactivity. Either dozens of experiments conducted over a period of more than three decades were wrong, or the scientists theories were. Now, in a set of four papers, University of Chicago scientists have demonstrated that the theories are correct.
"Our result is quite consistent with theoretical predictions," said Edward Blucher, Associate Professor in Physics at the University of Chicago. Blucher and Richard Kessler, also of the University of Chicago, and Sasha Glazov, who recently moved from Chicago to DESY, the German particle physics laboratory, authored the three papers, which were signed by their 55 fellow members of the Kaons at the Tevatron collaboration at Fermi National Accelerator Laboratory. The papers have been accepted for publication in Physical Review D and Physical Review Letters.

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.
When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...
Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
