A team led by Sean Ling observes melting in a superconductor using a single crystal of niobium and neutron imaging. The result shows that vortices can melt into a liquid at a specific temperature, paving the way for further studies on the mechanism of melting.
A physicist claims that scientists have underestimated the devastating potential costs of creating killer strangelets at a new US particle accelerator. The probability of such an event is tiny, but Kent argues that the scale of the destruction should be considered in risk assessments.
Researchers Jens Gundlach and Stephen Merkowitz present the most precise measurement of Isaac Newton's gravitational constant, reducing uncertainty by nearly a factor of 100. Their calculations yield an Earth mass of approximately 5.972 sextillion metric tons.
The National Science Foundation awards Cornell University $88 million to operate the Cornell Electron Storage Ring (CESR) accelerator for 54 months. The funding enables continued improvement of the facility for high-energy physics and X-ray research in various fields.
The American Physical Society is celebrating its 100th anniversary at a giant meeting in Atlanta, Georgia, from March 20-26, 1999. Over 7,000 physicists and experts will attend the event, which includes keynotes from national political figures and Nobel laureates.
The new wall chart graphically illustrates the basic structure of the nucleus, recent discoveries, and future directions in nuclear science. It includes sections on the expansion of the universe, nuclear matter phases, radio-active decay, controlled nuclear energy, and applications of nuclear science.
The Columbia supercomputer, QCDSP, can perform 400 billion calculations per second to simulate the three-trillion-degree conditions at the Big Bang. This will help physicists understand particle properties and calculate accurate masses and decay rates.
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.
Researchers at Purdue University have discovered that the electron's electromagnetic force may not be constant but rather increases towards the central core. The discovery reveals a cloud of virtual particles surrounding the core, which affects how we perceive the electromagnetic force from the electron.
