An international team of astronomers has unveiled the latest map of the distribution of dark matter in the universe. The invisible matter has been mapped by measuring the very weak effect on the images of distant, background galaxies, being distorted as their light rays pass intervening gravitating matter on their way to our telescopes - an effect known as gravitational lensing. The results appear consistent with the current "cold dark matter" model of the universe.

The star that exploded to create the nearest supernova of its type to be discovered since 1986 has been revealed by an international team including Oxford University scientists. New observations reported in two papers in this week's Nature show that a very dense, very small white dwarf star made of carbon and oxygen, orbiting another star, triggered the explosion. The observations also rule out previously popular models of what the second 'companion' star might look like.

The ATLAS(*) and the CMS experiments today presented updates on their searches for Standard Model Higgs bosons. The results, though impressive, do not yet contain enough data to make any definitive statement about the existence or otherwise of the elusive Higgs.

Both experiments have managed to constrain the possible masses of the Higgs down to a narrow range. For ATLAS that range is 116-130 GeV and for CMS it is 115-127 GeV (where a GeV is approximately the mass energy of a proton).

A new approach to measure the mechanical properties of living cells has been developed by researchers at Oxford Physics and Purdue University’s Birck Nanotechnology Center.This new technology could be used to diagnose human disease and better understand biological processes.

The LHCb experiment this week announced at the HCP Symposium in Paris a result which, if confirmed, would most likely be the first measurement performed at the LHC at CERN that cannot be understood within the long-established Standard Model of particle physics. This will require a deeper theory of 'new physics' to explain. Oxford is a founding member of the LHCb collaboration and Oxford physicists Mat Charles and Guy Wilkinson were lead analysts in the study presented in Paris.

Condensed Matter Physics is pleased to announce that Johannes Moeller, first year research student, has been awarded the Arthur H Cooke Memorial Prize 2011 for distinguished work by a first year research student.
Well done, Johannes!

Research by Oxford atmospheric physicist Karen Aplin with Paul Williams from Reading University's meteorology department was featured on Radio 4's PM programme on 19th October. Karen and Paul are publishing a paper in the Royal Meteorological Society's journal Weather about the representation of weather in classical orchestral music.

Amalia Coldea from the Quantum Materials group has been awarded the EuroMagnet prize 2011 for her outstanding contribution to the understanding of the electronic structure of iron-based superconductors by using high magnetic fields.

Ever wondered what collisions at the Large Hadron Collider look like?

Scientists at the world's biggest scientific experiment - the Large Hadron Collider (LHC) at CERN, Geneva - are trying to answer fundamental questions about the nature of the Universe, the origin of mass, the structure of space and time, and the conditions of the early universe. For those of us not lucky enough to have the world's highest energy particle smasher in our own back gardens, we can still get close to the action using an exciting new smartphone App.

New STFC funding will pave the way for the UK to maintain and strengthen its leadership role in the design and development of ELT instrumentation. The majority of the £2.1M grant to Oxford will fund work on HARMONI, with the remainder supporting continued development of the science drivers that underpin the E-ELT project.
