‘Naked’ black holes seen
Black holes are usually detected by the effects of their vast gravitational field on the orbits of nearby astronomical objects such as stars. Naked black holes have no such material near them making i...
Asteroid threat over estimated
A collision with a Near-Earth asteroid is believed to have wiped out the dinosaurs 65 million years ago. Near-Earth asteroids are usually piles of rock from the Mars-Jupiter asteroid belt whose orbit ...
Solitons formed in Bose–Einstein condensate
Bose–Einstein condensates are trapped atoms that are cooled to low temperatures and occupy the same quantum state. They are ideal for studying and manipulating quantum effects such as solitons a...
NAUTILUS detects cosmic rays
NAUTILUS was designed to observe the gravitational waves produced by collisions between objects such as black holes or neutron stars. According to the Frascati’s group calculations, signals from...
Adaptive-optics to cover the sky
Adaptive-optic telescopes differ from normal telescopes by using a thin flexible primary mirror that can easily be deformed. A bright guide star near the observing area acts as a “beacon” ...
Nuclear physics with lasers
About 20 years ago Toshi Tajima and John Dawson, then at the University of California at Los Angeles, suggested that laser-produced plasmas could be used to accelerate particles to high energies. The ...

CERN-Gran Sasso neutrino experiment is approved
Italy is paying over half of the cost of the SwFr 71million experiment, with voluntary contributions from Belgium, France, Germany and Spain covering the rest. The experiment will start taking data in...
Time unaffected by eclipse
The experiments were carried out by Thomas Udem from the Max-Planck Institute for Quantum Optics in Garching and colleagues. Udem and colleagues placed four atomic clocks – one rubidium clock, t...
Astronomy and physics dominate Science top ten
Confirmation that the universe is flat – expanding at just the right rate not to collapse – came from measurements of ripples in the cosmic background radiation left over from the big bang...
The decay route to teleportation
In quantum teleportation the quantum state of an object held by “Alice” is instantaneously sent to “Bob”. The new technique works by having two optical cavities that both conta...
