UK plans £65m facility

UK plans £65m facility

The UK at present has no nuclear physics facilities of its own, and very little investment in facilities overseas. “SIRIUS would open up many opportunities in a number of areas, most notably in materials science and nuclear astrophysics, ” says Bill Gelletly, the Surrey University physicist who is SIRIUS project scientist. SIRIUS may also have […]

US tops research league table

US tops research league table

Germany has a much less even pattern of citation than the US or England, with strengths in certain core fields, including physical sciences, maths and engineering, and weaknesses in economics and social science. France also performs well in engineering – despite a relatively modest output of papers – and is strong in applied maths and […]

Physics fails to keep pace in the UK

Physics fails to keep pace in the UK

Most of the extra money – £300m over three years – will go on a £600m Joint Infrastructure Fund that the government is setting up with the Wellcome Trust, the world’s largest biomedical research charity. The Wellcome Trust has also promised £110m towards the cost of a synchrotron radiation source called DIAMOND, and the government […]

Quantum teleportation goes beyond two states

Quantum teleportation goes beyond two states

In quantum teleportation the quantum state of an object held by “Alice” is instantaneously sent to “Bob”. The technique works by sending one half of an “entangled” light beam to Alice and the other to Bob. Alice measures the interaction of this beam with the beam she wants to teleport. She sends that information to […]

Microsoft’s war cry for science investment

Microsoft’s war cry for science investment

Myhrvold confirms the link between basic research and profit by pointing out that technology companies founded in the last 30 years that rely on basic research carried out since the second World War now have a market value of over a trillion dollars. He also criticizes certain “misconceptions” that exist about long-term research in industry. […]

Why some papers last longer that others

Why some papers last longer that others

The survey was carried out by using the Science Citation Index to count the number of citations received by papers published in 1954 volume of the Astrophysical Journal in each of the 40 following years. The same was done for papers published in the January 1959 issue of Physics Review over a 30-year period. Abt […]

Gamma-ray bursts spring more surprises

Gamma-ray bursts spring more surprises

There are a number of reasons why GRB980425 is associated with SN1998bw. Both occurred at the same time, at the same location and in the same direction as each other. SN1998bw is also a rare Type Ib/c supernova instead of the more common Type I or Type II explosions. Furthermore, material from the supernova was […]

Physics solves blood vessel mystery

Physics solves blood vessel mystery

Experiments on the effect have been performed by introducing a compound called angiotensin II into the blood stream of a rat. This compound narrows the diameter of the blood vessels, which increases the blood pressure and leads to the formation of the “sausage-string” pattern in the blood vessels. If the angiotensin II is removed, the […]

Quantum physics breakthrough wins Nobel Prize

Quantum physics breakthrough wins Nobel Prize

Two of the physicists, Horst L. Störmer from Columbia University, New York, and Daniel C. Tsui, Princeton University, Princeton, New Jersey, discovered the effect – called the fractional quantum Hall effect – in 1982. Robert B. Laughlin at Stanford University, California, explained their results one year later. The Hall effect was discovered in 1879. This […]
