  • The Calabi-Yau shape shown here is a two-dimensional visualization of the six additional spatial dimensions that string theory requires. Those dimensions, according to string theory, can be folded up in plain sight without our noticing.
  • Vinland Map targeted again By Dave Schleck, Daily PressOctober 5, 2003 NEWPORT NEWS — On the surface, the Vinland Map might be one of the great manuscripts of Western civilization. Supporters of the map housed at Yale University say it's a 15th-century document showing the first outline of North America and includes a legend describing the Vikings' discovery of the continent decades before Christopher Columbus set foot in the New World in 1492.

  • Scientist: Atoms, humans have similar mating rituals By Dave Schleck, Daily PressSeptember 7, 2003 Some physicists get their kicks out of watching couples break up. Lawrence Weinstein is one of them. The Old Dominion University professor and his graduate student Rustam Niyazov recently finished work on an experiment studying pairs of subatomic particles at the Thomas Jefferson National Accelerator Facility in Newport News, also known as Jefferson Lab.
  • Four Experiments Give Evidence of an Exotic Baryon With Five Quarks By Bertram Schwarzschild, Physics TodaySeptember 2003 It's been a long-standing puzzle that the quantum numbers of all the known mesons and baryons could be attributed to bound states of two or three quarks. But now the first exception has apparently been found.

  • Navy Tries Again With Laser By Matthew Dolan, The Virginian-PilotAugust 18, 2003 Entering a seemingly futuristic world more familiar to fans of Star Wars, Battlestar Galactica and all things Trekkie, the Navy is going laser. Underneath a nondescript research building off Interstate 64, scientists with the Department of Energy's Thomas Jefferson National Accelerator Facility have built the most powerful, free-electron laser in history.
  • August 5, 2003, update on the furthering search for evidence of the pentaquark: The SAPHIR collaboration at the ELectron Stretcher Accelerator (ELSA) in Bonn, Germany, announced at the beginning of August evidence of the pentaquark from data they took in 1997/98. The SAPHIR collaboration announced evidence for Theta-plus with a mass of 1540 MeV and a width of less than 25 MeV, compatible with experimental results from SPring-8, ITEP and Jefferson Lab.

  • Catching T-waves Terahertz radiation is gentle but piercing By Kenneth Terrell, US NewsJuly 28, 2003 Call it Karnak for the age of anthrax. In one envelope is a letter from Grandma; in the other is a life-threatening dose of a biological weapon. How can the post office tell the difference before you open your mail? The answer could lie in a mostly untapped band of the electromagnetic spectrum, the terahertz range.

  • Lab finds evidence of tinier part of matter By Dave Schleck, Daily PressJuly 6, 2003 NEWPORT NEWS — Scientists at the Thomas Jefferson National Accelerator Facility have evidence of a new subatomic particle called a pentaquark. Before your eyes glaze over, know that pentaquarks could help physicists understand the basic building blocks of matter.
  • Wild Bunch: First five-quark particle turns up By Peter Weiss, Science NewsJuly 5, 2003 Physicists on three international teams have recently spotted what's most likely a long-sought subatomic particle known as a pentaquark. It contains five components—four quarks and one antiquark—which are among the most fundamental bits of matter yet known. No subatomic particle detected previously contains more than three of those building blocks.
  • Five-quark particle may exist Goleta Valley VoiceJuly 4, 2003 There's a new kid on the quantum physics block, some U.S. and Japanese scientists announced this week: a five-quark particle, or "pentaquark." In separate experiments, U.S. scientists and a group in Japan both announced discovery of a five-quark particle. This particle, if verified by more research, would constitute a previously unknown form of matter.

  • Pentaquark discovery confounds sceptics By Hazel Muir, New ScientistJuly 2, 2003 A brand new sub-atomic particle called the pentaquark has made its debut at labs in Japan and the US. Unlike ordinary protons and neutrons in atomic nuclei, which contain three quarks, the pentaquark has five. The result has delighted Russian physicists who predicted the mass of the particle in 1997, but met a lot of scepticism from their peers.

  • 'Pentaquark' hints at answers to matter Washington TimesJuly 1, 2003 OSAKA, Japan — Physicists have discovered a new class of subatomic particles, offering unexpected insights into the building blocks of matter. The discovery, published in Physical Review Letters, involves tiny particles called "quarks," the bricks and mortar of protons and neutrons in the atomic nucleus.
