Scientists at the University of California, Berkeley, and Lawrence Berkeley National Laboratory in the US, have performed sophisticated laser measurements to detect the subtle effects of one of nature's most elusive forces - the "weak interaction". Their work, which reveals the largest effect of the weak interaction ever observed in an atom, is reported in Physical Review Letters and highlighted in the August 10th issue of APS's on-line journal Physics (physics.aps.org).Along with gravity,...

At a recent physics seminar at the Department of Energy's Fermi National Accelerator Laboratory, Fermilab physicist Pat Lukens of the CDF experiment announced the observation of a new particle, the Omega-sub-b (ÃŽ©b). The particle contains three quarks, two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the much more common proton and has about six times the proton's mass.The observation of this "doubly strange" particle, predicted by the Standard...

Scientists of the CDF experiment at the Department of Energy's Fermi National Accelerator Laboratory announced March 17 that they have found evidence of an unexpected particle whose curious characteristics may reveal new ways that quarks can combine to form matter. The CDF physicists have called the particle Y(4140), reflecting its measured mass of 4140 Mega-electron volts. Physicists did not predict its existence because Y(4140) appears to flout nature's known rules for fitting quarks and...

A group of 28 scientists at the U.S. Department of Energy's Fermi National Accelerator Laboratory (Fermilab) have observed particle collisions that produce single top quarks. The observation resulted from proton-antiproton collisions measured by the DZero detector in Fermilab's Tevatron, currently the world's most powerful operating particle accelerator. The discovery of the single top quark confirms critical parameters of particle physics, including the total number of quarks, and is...

The world's newest "super microscope" at Isis in Oxfordshire will allow scientists to see things 10,000 times thinner than a human hair. The machine is known as a pulsed neutron source. And now that the second target station "Isis 2" is open, up to 40 different experiments can run side by side. Physicists from around the world are flying in to seek an audience with the oracle, which resides at the Rutherford Appleton Laboratory, at Harwell Science and Innovation Campus. "Essentially, it's a...

New analytical tools coming on line at the Spallation Neutron Source, the Department of Energy's state-of-the-art neutron science facility at Oak Ridge National Laboratory, include a beam line dedicated to nuclear physics studies. The Fundamental Neutron Physics Beam Line (FNPB) has opened its shutter to receive neutrons for the first time. Among the nuclear physics studies planned for the new, intense beam line are experiments that probe the neutron-related mysteries associated with the "Big...

University of Michigan physicists played a leading role in the discovery of a new particle, the Omega b baryon, which is an exotic relative of the proton. It was detected for the first time in a particle accelerator at Fermi National Accelerator Laboratory (Fermilab) in Illinois, Fermilab has announced. The heavy particle is scarce today, but scientists believe it was abundant soon after the Big Bang. "This discovery helps us understand how matter was formed in the universe. It shows the...

Physicists of the DZero experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory have discovered a new particle made of three quarks, the Omega-sub-b (ÃŽ©b). The particle contains two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the much more common proton and weighs about six times the proton mass. The discovery of the doubly strange particle brings scientists a step closer to understanding exactly how quarks form matter...

3-D images are not only useful in medicine; the observation of internal structures is also invaluable in many other fields of scientific investigation. Recently, researchers from the Hahn-Meitner-Institute (HMI) in Berlin in cooperation with University of Applied Sciences in Berlin have succeeded, for the first time, in a direct, three-dimensional visualization of magnetic fields inside solid, non-transparent materials. This is announced by Nikolay Kardjilov and colleagues in the current...

Researchers at the National Institute of Standards and Technology (NIST) and the University of Maryland have developed a new optical method that can detect individual neutrons and record them over a range of intensities at least a hundred times greater than existing detectors. The new detector, described at the March Meeting of the American Physical Society* by Charles Clark, a Fellow of the Joint Quantum Institute of NIST and the University of Maryland, promises to improve existing neutron...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
