About the speaker

Reuben E Brigety II was confirmed as the 29th United States Ambassador to the Republic of South Africa on 21 July 2022.

Previously, he served as the 17th Vice-Chancellor of the University of the South and Mayor of Sewanee from June 2020 until December 2021, and as the Dean of the Elliott School of International Affairs of the George Washington University from 2015 to 2020. Ambassador Brigety’s most recent diplomatic assignment was serving as the US Representative to the African Union and US Permanent Representative to the UN Economic Commission for Africa from September 2013 to September 2015. Previously, Ambassador Brigety served as the Deputy Assistant Secretary of State in the Bureau of African Affairs and as Deputy Assistant Secretary of State in the Bureau of Population, Refugees, and Migration.

A native of Jacksonville, Florida, Ambassador Brigety also held appointments as Assistant Professor of Government and Politics at George Mason University and at the School of International Service at the American University between August 2003 and April 2009. In addition, Ambassador Brigety was a researcher with the Arms Division of Human Rights Watch (HRW) from August 2001 to May 2003, where he conducted research missions in Afghanistan and Iraq. Before joining HRW, Ambassador Brigety was an active-duty US naval officer and held several staff positions in the Pentagon and in fleet support units.

Ambassador Brigety is a 1995 Distinguished Midshipman Graduate of the US Naval Academy, where he earned a BSc in Political Science (with merit), served as the Brigade Commander, and received the Thomas G Pownall Scholarship. He also holds an MPhil and a PhD in International Relations from the University of Cambridge, England, as well as a Doctor of Humane Letters (honoris causa) from Old Dominion University. Ambassador Brigety is a life member of the Council on Foreign Relations, a recipient of the council’s International Affairs Fellowship, and a fellow of the American Academy of Diplomacy.He is married to Dr Leelie Selassie, and together they have two sons.

Champagne and cancer have more in common than you might think

No, a glass of champagne will not cure cancer....

…But they have more in common than you might think.

Researchers from the Departments of Microbial Biochemical and Food Biotechnology, Physics and the Centre for Microscopy at the University of the Free State in South Africa were recently exploring the properties of yeast cells in wine and food to find out more of how yeast was able to manufacture the gas that caused bread to rise, champagne to fizz and traditional beer to foam. And the discovery they made is a breakthrough that may have enormous implications for the treatment of diseases in humans.

The team discovered that they could slice open cells with argon gas particles, and look inside. They were surprised to find a maze of tiny passages like gas chambers that allowed each cell to ‘breathe.’ It is this tiny set of ‘lungs’ that puts the bubbles in your bubbly and the bounce in your bread.

But it was the technique that the researchers used to open up the cells that caught the attention of the scientists at the Mayo Clinic (Tumor Angiogenesis and Vascular Biology Research Centre) in the US.

Using this technology, they ultimately aim to peer inside cells taken from a cancer patient to see how treatment was progressing. In this way they would be able to assist the Mayo team to target treatments more effectively, reduce dosages in order to make treatment gentler on the patient, and have an accurate view of how the cancer was being eliminated.

“Yes, we are working with the Mayo Clinic,” said Profes Lodewyk Kock from the Microbial, Biochemical and Food Biotechnology Department at the UFS.

“This technique we developed has enormous potential for cell research, whether it is for cancer treatment or any other investigation into the working of cells. Through nanotechnology, and our own invention called Auger-architectomics, we are able to see where no-one has been able to see before.”

The team of Prof Kock including Dr Chantel Swart, Kumisho Dithebe, Prof Hendrik Swart (Physics, UFS) and Prof Pieter van Wyk (Centre for Microscopy, UFS) unlocked the ‘missing link’ that explains the existence of bubbles inside yeasts, and incidentally have created a possible technique for tracking drug and chemotherapy treatment in human cells.

Their work has been published recently in FEMS Yeast Research, the leading international journal on yeast research. In addition, their discovery has been selected for display on the cover page of all 2013 issues of this journal.

One can most certainly raise a glass of champagne to celebrate that!
