Researchers at Case Western Reserve University have developed a new method of supershielding, allowing magnetic fields to be completely contained without using traditional shielding methods. This invention has the potential to protect modern technologies from interference and destruction.
The Hertz Foundation has awarded a $1 million endowment to establish an endowed professorship at UC Davis in recognition of Edward Teller's contributions to physics. Earnings from the endowment will support the chair's teaching, research, and administrative work.
Researchers have revived a theoretical concept for faster-than-light travel by using a 'bubble' of warped space, which can be created with modest amounts of energy. The idea, inspired by Dr Who's Tardis, involves shrinking the departure point and expanding the destination, effectively transporting objects at faster-than-light speeds.
The Far Ultraviolet Spectroscopic Explorer (FUSE) will test the Big Bang theory and collect comprehensive observations of the Milky Way's star-forming regions. Launched on June 23 from Cape Canaveral Air Station, the three-year mission marks a first for an academic department in managing a satellite.
Recent experiments by physicists at the University of Notre Dame and Tohoku University have found that current theories describing turbulence may need modifications, particularly in extreme situations. The findings suggest that ultra-hard turbulence, a predicted state of turbulent flow, may not exist as previously thought.
Rocky Kolb will discuss the first second in the life of the universe, describing a hot primordial soup of 'elementary' particles. He explores how this soup has cooled and condensed into the cosmic structure we see today. Kolb's work is praised for its clarity and insight.
Physicists at Fermilab's KTeV experiment report a large and unexpected direct CP violation, ruling out the Superweak Theory. The finding exceeds previous expectations, raising questions about its accommodation within the Standard Model.
Physicist Janet Conrad is building an underground vat to trap oscillating neutrinos and observe their transformation into another type. The experiment aims to prove that neutrinos have mass, a discovery that has already shaken the physics world.
Physicists suggest MACHOs may be made of a weird kind of mirror matter generated in the big bang, with potential for mirror planets and organisms. This theory could explain the presence of invisible stars on the outskirts of our Galaxy.
Anthony Leggett, a professor of physics at the University of Illinois, has been named an Honorary Fellow of the Institute of Physics. He was recognized for his fundamental contributions to theory of superfluidity in helium-3 and quantum mechanics of macroscopic systems.
Brown dwarf Cha Ha 1 is the youngest known member of the Chamaeleon dark cloud, with a mass of 4-5% of the Sun's mass and an age of one million years. Its X-ray emission was detected using the ROSAT satellite.
Researchers John Toner and Yuhai Tu develop a theory explaining how birds move as a single unit despite frequent misjudgments and limited visibility. By making analogies to physics phenomena like magnet alignment and fluid flow, they provide insights into other animal collectives and even auto traffic flow.
A team of physicists from the University of Washington has found evidence that subatomic particles known as neutrinos have mass. The discovery, made in a deep underground laboratory, suggests that muon-neutrinos are changing into other types, indicating they must have mass.
The National Academy of Sciences has elected 60 new members for their distinguished achievements in original research. The newly elected members include experts from top universities such as North Carolina State University, Columbia University, and Yale University.
Researchers at Ohio State University have developed a new model of atomic forces that may solve a long-standing problem in particle physics. The work aims to reconcile physicist Richard Feynman’s 1970s model of the proton with modern views of quark structure, simplifying equations and potentially aiding experimental calculations.
The American Institute of Physics hosts a major physics meeting in Columbus, featuring discussions and press conferences among attendees. Online abstracts and a virtual pressroom are also available on the APS website, providing access to meeting information, schedules, and related resources.
Gordon Kane highlights the importance of models in physics, citing Aristotle's flawed theory as an example. He emphasizes that scientists test multiple models against reality to determine which one is correct. The Standard Model of particle physics is a prime example, developed after decades of research and testing.
Researchers Mark Boslough and Randy Gladstone suggest that entry of ordinary meteoroids can form dark spots similar to those observed by satellites, contradicting a theory of frequent small comet bombardment. Their study provides evidence for the existence of high-altitude plumes generated by meteors.
Researchers at the University of Notre Dame have discovered a new subnuclear particle, an exotic meson, which is composed of quarks and antiquarks rather than just one type. The discovery was made possible by a high-energy particle experiment conducted at Brookhaven National Laboratory.
Physicists have demonstrated that single photons and other quantum particles can store a maximum amount of readable information in the presence of noise and real-world disturbances. This finding provides insights into how little energy is required to store complex messages, advancing the idea that information is physical in nature.
Astronomers have detected radio emission from a cosmic gamma-ray burst using the National Science Foundation's Very Large Array (VLA) radio telescope. The detection may help resolve one of the biggest mysteries in astrophysics, providing unprecedented knowledge about gamma-ray bursts and their parent objects.
Researchers found an unexpected orientation in space, measured through light polarization from distant galaxies. The 'corkscrew effect' indicates a universal axis that orients the universe.
Researchers at University at Buffalo demonstrate strongest evidence yet for reentrant superconductivity, a phenomenon where magnetic fields enhance superconductivity rather than destroy it. The findings have potential practical applications in energy storage and magnetic resonance imaging.
Researchers observed hundreds of thousands of high-energy collisions between protons and positrons, far exceeding expected statistical probabilities. The unexpected results may indicate new physics or a mistake in understanding what's inside the proton.
