Nobel laureate John Fenn passes away

15 Dec 2010

Professor John B. Fenn, 1917-2010

Professor John B. Fenn, who received the the Nobel Prize in Chemistry in 2002 for his work in electrospray ionization, passed away on Friday December 10 at the age of 93.

His work was instrumental in enabling the rapid analysis of the structure of proteins and other biomolecules via mass spectrometry, and Prof. Fenn remained a mainstay at scientific conferences and an active researcher well into his 90s.

You can see Prof. Fenn’s Nobel Lecure, “Electrospray Wings for Molecular Elephants” on the official website of the Nobel Prize.

A remarkable scientist and an inspiration to many, there is no doubt that John Fenn will be greatly missed.

Glowing glucose tracker

20 Oct 2010

H Shibata et al, Proc. Natl. Acad. Sci. USA, 2010, DOI: 10.1073/pnas.1006911107

Japanese researchers have developed microscale beads that visibly glow under the skin in response to blood glucose levels, signalling a potential end to repeated fingertip prick blood tests for diabetics needing to monitor their glucose levels.

Looking cancer in the eye

12 Oct 2010

Scientists from the UK and Japan have discovered a way to identify pre-cancerous stem cells in the eye using absorbance spectra data.

Characterising cells in the cornea could prevent recurring cancer

Cancerous tumours in the cornea can cause loss of vision and, if left untreated, can become aggressive. Treatment is to cut out the cancerous cells but there is often a high chance of the disease recurring. Identifying normal tissue that has the potential to become cancerous prior to treatment could ensure complete removal and lower the risk of cancer reoccurring after treatment.

Despite decades of intense research, there are currently very few proficient stem cell biomarkers for the cornea. Now a team lead by Frank Martin at the University of Lancaster, UK, have used the sensitive and high-throughput approach of synchrotron-based Fourier-transform infrared microspectroscopy to create an image map of cornea samples to recognise differences between cell types and highlight prospective biomarkers.
