Measurement Across Scales

Our multidisciplinary community uses quantitative, experimental and theoretical approaches from the physical sciences to create an integrated understanding of biological systems across length scales. This approach offers new insights into fundamental biological systems and gives fresh perspectives to life sciences challenges.

Research Highlights

  • A cross-disciplinary team have developed a new technique for detecting reactive oxygen species in situ in the cell. The team comprises professors from Physics, Chemistry and Biosciences and uses an innovative fluorescence microscopy technique combined with specially designed molecules developed by the SME LightOx. This Durham University spin-out company was founded in 2017 to further develop innovate research from the groups of Professors Ambler and Whiting. Find out more here.
  • Interdisciplinary approaches are bringing new insights to the understanding of stress granules. These are biomolecular condensates that are formed in response to cellular stresses and have important intracellular roles. The team, including Professors Halim Kusumaatmaja (Durham Physics) and Sushma Grellscheid (University of Bergen) is using a novel approach to study the rheological behaviour of these condensates. Find out more here.
  • The use of bacteria to give synthetic vesicles mobility has been discovered by a multidisciplinary team from Durham and Edinburgh Universities. Dr Margarita Staykova (Durham Physics) and her colleagues have shown that when E coli are enclosed in a synthetic vesicle (a spherical membrane bag), the bacteria push out into the membrane to form tubes enclosed in membrane. This is similar to their behaviour during a bacterial infection, with the result that the membrane tubes formed propel the vesicle into motion. Find out more here.

  • Bullseye Analysis

    Professors John Girkin (Durham Physics), Carrie Ambler (Durham Biosciences) and Andrew Whiting (Durham Chemistry) have developed a new FRAP microscopy technique to detect reactive oxygen species in situ in the cell, using novel technology from the spin out company LightOx.

SOFI CDT

The EPSRC Centre for Doctoral Training in Soft Matter and Functional Interfaces (SOFI CDT) was launched in 2014 and led by Professor Tom McLeish FRS. Now in its second iteration SOFI2, it is led by Professor Colin Bain (Durham Chemistry) and brings together expertise from the universities of Durham, Edinburgh and Leeds and from a wide range of industrial partners.

 

Physics of Emergent Behaviour (PoEB) IV conference

The 4th edition of the IOP PoEB conference was held in Harrogate (UK) after the 2023 Physics of Life conference. The organising committee included the BSI’s Dr Margarita Staykova (Durham Physics) and the theme of the meeting was the diverse types of phase transitions found in biology.

 

  • SOFI CDT

    SOFI2 CDT brings together expertise from the Universities of Durham, Edinburgh and Leeds as well as from the industry leaders in soft matter and functional materials applictions.

  • Physics of Emergent Behaviour (PoEB) IV conference

    The 2023 IOP PoEB conference was co-organised by Dr Margarita Staykova (Durham Physics). It focussed on phase transitions in biological systems including tissues and organs, membranes, cytoplasm and the cytoskeleton.
