AMS hints at cosmic-ray mystery
The experiment also found that changes in the strength of the Earth’s magnetic field with latitude do not alter the number of low-energy protons hitting the Earth’s atmosphere. However the...
Defects work for laser
The photonic crystal was made by using an ion beam to drill a 2D hexagonal array of holes in a layer of indium gallium arsenide phosphide (InGaAsP). The regular spacing of the holes means that only ce...
Has man caused climate change?
The Earth’s average global temperature has increased by 0.6 Kelvin in the past 100 years. There are believed to be four main processes that can effect the Earth’s climate. Two of these, sm...

Neutrino lab sees “first light”
The observatory is a joint project between Canada, the US and the UK, and was officially opened last year. It is the first detector that is capable of distinguishing between the three different types ...
Element 118 discovered at Berkeley
The new elements were made by bombarding a lead-208 target with an intense beam of high- energy krypton-86 ions over an 11-day period. The krypton ions were accelerated by the 88-inch cyclotron at the...
Fractals determine date of paintings
The physicists scanned a series of Pollock’s artworks into a computer and masked each painting with a series of grids. They then counted the number of squares that contained part of the painted ...

Hubble finds planetary transition point
The results help to confirm the view that other planetary systems form in ways similar to our solar system. The Kuiper belt is a disk of dust, gas and icy comets stretching from 40 to 10000 times the ...
Café society gets scientific
French cafés have long been a meeting point for intellectuals. In the 18th century Victor Hugo met fellow revolutionaries at the Procope in Paris, and in the 1950s groups of existentialists, incl...
First collisions at BaBar
The collisions are termed “asymmetric” because the electrons are accelerated to 9 GeV – three times the energy of the positrons. As the two beams collide, they generate B mesons that...

Game, set and slower match
To many sports fans, the month of June is synonymous with the Wimbledon tennis tournament. Thousands of people will flock to the All England Lawn Tennis Club to watch the players battle it out on the ...
