Electrons may undergo fission in liquid helium at temperatures near absolute zero, violating the long-held notion that elementary particles cannot be broken into two pieces. Experimental evidence supports this theory, which suggests that light can cause an electron's bubble to divide into smaller bubbles.
Physicists at the University of Illinois have made new measurements that provide information about how different flavors of quarks in a proton generate its magnetic moment. The results suggest that the contribution from the strange quark is significantly positive, contrary to most theoretical models.
A Duke study reveals that the pressures under poured sandpiles are highest at their peripheries due to unbalanced distributions of stresses. In contrast, showered sand piles concentrate stresses at their centers like medieval cathedrals' flying buttresses. This research has practical importance for structures prone to self-destruction.
The Williams College research team observed a two-and-a-half-minute period of totality in a clear sky, collecting fabulous scientific data that will keep researchers busy for years. The experiments focused on understanding the corona's temperature and magnetic field, which can reach temperatures of up to four million degrees Celsius.
A team of Williams College astronomers will conduct scientific experiments during the August 11 solar eclipse to study the coronal heating of the sun. The research, supported by grants from NASA and National Geographic, aims to observe rapid oscillations in the corona using advanced telescopes and optics.
A team of scientists from Montana State University designed an experiment to study the role of gravity on infection-fighting white blood cells. The goal is to understand why astronauts are more vulnerable to infections in space and develop pharmaceuticals to boost immune responses.
Researchers at Lawrence Berkeley National Laboratory have discovered two new superheavy elements, 116 and 118, using an intense beam of high-energy krypton ions. The discovery was made possible by the newly constructed Berkeley Gas-filled Separator, which allows for unprecedented efficiency and background suppression.
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.
Researchers created a wax experiment that replicates ocean floor spreading, allowing them to study millions of years of geological time. The experiments revealed the formation of microplates, tiny chunks of solid wax that roll up and rotate in a spiral shape, mirroring the Earth's natural phenomenon.
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.
NASA is investing half a million dollars in an experiment to create a device that shields a rocket from the Earth's gravity. The project, led by physicist Ronald Koczor, aims to replicate elements of Russian scientist E. E. Podkletnov's controversial experiments on antigravity.
Researchers found that below a certain electron density, electrons behaved like insulators, but above this density, a conducting state was observed. The team proposes that a novel kind of superconductor is responsible for this phenomenon.
Researchers have found that a cluster of 60 helium atoms is sufficient to create a superfluid, defying gravity and exhibiting macroscopic properties. This discovery was made possible by the development of new methods to explore superfluidity on a microscopic scale.
Researchers at Duke University discovered that granular particles can form dramatic chains to relieve stress, leading to potential explanations for self-destruction in passive containers. The study may also shed light on natural phenomena like earthquakes and the behavior of materials under low gravity.
Researchers aim to understand how the sun's corona reaches temperatures of two million degrees Celsius despite the surface being only 6,000 degrees. The team will use various techniques, including comparing electronic images and searching for rapid oscillations, to gather data during the February 26 eclipse.
The Physics 2000 Project offers a fun and interactive approach to learning physics, featuring over 30 virtual experiments and explanations by cartoon characters. Users can explore topics such as X-rays, wave interference patterns, and electromagnetic radiation in an engaging and accessible way.
Physicist John Lipa's Shuttle Experiment could revolutionize electronics miniaturization. The experiment aims to measure the confinement effect on materials in ultra-low temperatures.
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 at University at Buffalo successfully demonstrate collective flow of nucleons resulting from stopping high-energy lead beam, a critical prerequisite for producing quark/gluon plasma. The achievement confirms theoretical predictions and brings optimism to the field of quark/gluon plasma detection.
