An experimental limit on the charge of antihydrogen

Last April Nature Communications published a paper [1] outlining a new technique in measuring the effect of gravity on neutral antimatter specifically regarding the trapping of antihydrogen. This recent experimental achievement has lead to a range of new possibilities in exploring fundamental physical phenomena, including most recently a paper published today in Nature Communications [2], signifying the charge neutrality of antihydrogen. Antimatter is predicted to have the same properties as matter aside from having an opposite charge. The universe is composed with a larger proportion of matter. One of the biggest questions in physics is to understand why there...

Solar Electricity – A multi-scale challenge

Last night began the start of this years Institute of Physics Merseyside Branch Events 2013-2014. This years programme  kicked off with a talk from Professor Ken Durose in the Surface Science Research Centre. There was a great turn out for this event, more than anticipated, including A-Level students, undergraduate students, lecturers and various others. Ken Durose  joined Liverpool University in 2011 and is a research leader for photovoltaic materials in the new Stephenson Institute for Renewable Energy. He delivered a very interesting talk on the history behind solar electricity, the achievements and the problems faced by photovoltaic materials. The...

EuroSpine – The Spine Society of Europe

During the 2nd to the 4th of October, The Arena and Convention centre in Liverpool has played host to the annual International Medical Congress of EuroSpine – the spine society of Europe. This meeting is EuroSpine’s biggest event and it was the first time that the meeting was held in the UK so it was an honour that they chose to host the event in Liverpool. Spinal injuries can affect anyone at any time. In the UK and Ireland around 1000 people develop a spinal cord injury yearly and every 8 hours someone is paralysed in the UK. There...

The impact of UNESCO on the scientific world and society at large

As part of the Science in Society series a talk was hosted by Professor Maciej Nalecz, the Director of the Division of Basic and Engineering Sciences at UNESCO (United Nations Educational, Scientific and Cultural Organisation). I had heard of UNESCO before attending this talk but my knowledge as to what they do was very basic. After this talk however I was well informed of the aims of UNESCO and what they actually do in terms of science all across the world. To start with UNESCO is an organisation that was founded in 1945 consisting of 195 member states. The...

Joseph Mckenna and an insight into the world of antihydrogen

Joseph McKenna is a current 3rd year Physics PhD student at the University of Liverpool. Joseph began life at Liverpool as an undergraduate living in Rankin Halls. He has fond memories of these halls but feels glad that students don’t have to live there anymore. Joseph has come a long way from his first year spent in Carnatic; having since worked in various places including Cheddar Caves and Gorge, GSI, as well as at the ALPHA experiment in CERN. Joseph is now currently part of the ALPHA collaboration.  Today a paper was released by The ALPHA Collaboration regarding ‘a...
