New Toolkits for Positron Emission Tomography

Written by

PET scanners make use of radioactive tracers.

Positron emission tomography (PET) is a powerful imaging technique that uses radiotracers injected into the body to look at biology in tissues and cells, making it an important tool in biomedical research and drug development. Dr Victor Pike, Chief of the PET Radiopharmaceutical Sciences Section of the Molecular Imaging Branch at the National Institute of Mental Health in the U.S., […]

The biology of ageing

Written by

Biology of ageing Dr Nan-ping Weng Research Outreach

What causes ageing? Is it inevitable? Could it be slowed or even reversed? Humans have wanted to know the answer to these questions ever since we became aware of our own mortality. Despite the tremendous advances that have been made in our scientific understanding over the past century, ageing remains one of the greatest mysteries in biological science. But scientists, […]

Open-source bioinformatic solutions for ‘Big Data’ analysis

Written by

In this research article: Drs Griffin and Jagtap’s research focuses on the Galaxy-P project – developing, testing, optimising and applying multi-omics software tools to a variety of biological questions, including cancer and big data research.

Drs Tim Griffin and Pratik Jagtap along with the Galaxy-P team from the University of Minnesota are working to develop workflows on an open source platform for the analysis of multi-omic data. They are currently focusing on using a Galaxy-based framework to investigate the integration of genomic datasets with mass spectrometry-based ‘omics’ data. But in the long term, they aim […]
