Researchers at RHIC have made precision measurements of hypertriton and antihypertriton binding energy and mass, shedding light on symmetry violations in neutron stars. The results could have significant implications for understanding astrophysical phenomena involving strange quarks.
Science communicators will share unique approaches to engage the public through popular culture, including NASCAR and Star Wars. They aim to bridge the divide between science and the general public by making physics more relatable and accessible.
Scientists at ORNL solved a 50-year-old puzzle explaining why beta decays are slower than expected by including subtle effects in theoretical models. The team used ORNL's Titan supercomputer to simulate tin-100 decay into indium-100, demonstrating increased confidence in computing nuclear processes.
Marialis Rosario-Franco, a UTA doctoral student, has been awarded the Gröte Reber Doctoral Fellowship to study exomoons in four-body systems and their potential detection by modern radio telescopes. The fellowship allows her to conduct observational research at the NRAO's Very Large Array and Long Wavelength Array.
Narlikar shares personal reminiscences on the evolution of cosmology over six decades, highlighting the increase in confidence in the standard model. However, he also notes that this model lacks independent observational support and an established theoretical base.
Scientists measured a time delay of 100 milli-seconds between X-rays and optical flashes from the jet emitted by V404 Cygni's black hole. This delay indicates the inner acceleration zone in the jet is approximately 30,000 kilometers away from the event horizon.
Nuclear physicists at Brookhaven National Laboratory's STAR detector have revealed new details about the fundamental particles that make up our world. They found more heavy particles emerging from the fat part of a collision, indicating that heavy particles get caught up in the flow of quark-gluon plasma.
Aging stars stop slowing down as their magnetic field interacts with a wind of particles flowing away from its surface, according to research published in Nature. This discovery challenges previous theories on stellar rotation and has implications for understanding how the Sun influences its local environment, including planets.
Researchers use the Very Large Telescope Interferometer to study a young star with a large proto-planetary disk. They find a significant gap in the inner regions, suggesting a gravitational influence from forming planets.
A Queen's University PhD student is conducting the first systematic population study of magnetosphere-host stars, finding that plasma density within all such magnetospheres is far lower than predicted. This suggests that plasma might be escaping gradually, maintaining magnetospheres in an essentially steady state.
Researchers found that the magnetic field of a neutron star takes on a stable structure and evolution slows down, challenging previous theoretical models. The discovery could help scientists measure neutron star properties and gain insights into matter at extreme densities.
Renowned physicist Lawrence Krauss believes science fiction is not a match for reality. He argues that science fiction often fails to capture the complexity of scientific discoveries. Meanwhile, Krauss suggests exploring real-world applications of science fiction concepts, such as warp drive and teleportation, which may be possible in ...
A University of Alberta physicist collaborated with amateur astronomers to confirm the periodic bursts of light from a binary star, SS Cygni, 370 light years away. The team re-examined an established theory and confirmed its accuracy using data from ground-based radio telescopes and optical observations.
Using Star Trek's advanced technologies as a gateway to explore fundamental physics concepts, ASU Professor Lawrence Krauss engages lay audiences and sparks their interest in science. He examines the feasibility of phenomena like wormholes, warp drives, and time travel within our current understanding of physics.
A laboratory experiment has successfully modeled stellar jets, revealing that magnetic forces shape these objects in a non-linear way. The findings suggest that the jets are fired out like bullets or buckshot, rather than breaking into pieces as previously thought.
Rice University is leading an international team in building a cylindrical bank of over 23,000 particle detectors for the Solenoidal Tracker at RHIC. The collaboration, valued at $7 million, demonstrates robust scientific cooperation between US and Chinese institutions.
The US Physics Olympiad team consists of 24 high school students from 14 different states who were selected to compete in the International Physics Olympiad. The team will undergo a week-long physics 'boot camp' and attend lectures by prominent scientists before traveling to Taipei, Taiwan for the competition.
Lawrence Schulman proposes a new scientific spin on science fiction, suggesting the possibility of reverse arrow systems where broken eggs re-form and timeline runs backwards. He uses statistical computer modeling to show that such systems could exist in regions with dark matter.
Lawrence Krauss, a prominent astrophysicist, has won the AAAS Public Understanding of Science and Technology Award for his efforts to improve communication between scientists and the public. His work aims to promote scientific literacy and critical thinking, particularly in addressing creationism in public schools.
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.
A team of astronomers has developed a 3-D globe-like image of the Helix nebula, allowing them to inspect it from all sides. The image reveals evidence that the nebula behaves like a double-headed garden sprinkler, with each side ejecting gas at similar structures.
Scientists successfully converted energy in the form of light into matter, creating electrons and positrons. The experiment used high-energy electrons and photons to produce an incredible amount of power in a tiny area, marking a major breakthrough in understanding quantum electrodynamics.
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.
