Research by scientists from University College London (UCL) and Tel Aviv University shows that the tuberculosis infection is 3,000 years older than was previously imagined and that TB in people evolved before bovine TB. Professor Israel Hershkovitz of Tel Aviv University noticed lesions that are a sign of TB in the bones of skeletons discovered at Alit-Yam, a 9,000 year-old pre-pottery Neolithic village. Dr. Helen Donoghue and Dr. Mark Spigelman, of the UCL Centre for Infectious Diseases & International Health, led an international collaborative team through analysing the bones using scientific techniques to reveal DNA and cell wall lipids from mycobacterium tuberculosis, the principal agent of human TB. The DNA in the excavated bones was sufficiently well-preserved for molecular typing to be carried out and the analysis of the bacterial cell wall lipids by high performance liquid chromatography provided evidence of tuberculosis.

Inside the Laboratory: The Schug Group at the University of Texas at Arlington
March 22nd 2024In this edition of “Inside the Laboratory,” Kevin Schug, PhD, a full professor of chemistry at the University of Texas at Arlington, discusses his laboratory’s group work in environmental monitoring around water and soil quality near oil and gas extraction, using techniques such as liquid chromatography (LC), gas chromatography (GC), supercritical fluid chromatography (SFC), and coupling these techniques with mass spectrometry (MS).
