Dr Francois Jacobs
Dr Francois Jacobs received his Doctor of Philosophy degree in Chemistry on Monday, 9 December.

Dr Francois Jacobs, a 30-year-old PhD graduate, has recently returned from an intensive training workshop in Harwell, Oxford, courtesy of the David Blow Bursary. This prestigious award recognises outstanding African researchers making significant contributions to macromolecular crystallography.

Dr Jacobs earned his Doctor of Philosophy degree in Chemistry on Monday, 9 December. While earning a PhD by the age of 30 was not part of his initial plan, he always aspired to pursue higher education. “From a young age, I had a strong desire to study at university. Once I got there, my ambition shifted towards obtaining a PhD,” he says, reflecting on the journey that led to this remarkable achievement.

Groundbreaking research on cancer and antibiotics

Dr Jacobs’ research addresses some of the most pressing health challenges of our time: cancer and antibiotic resistance. Using crystallography, he investigates the interactions between newly developed anticancer and antibacterial compounds and biological structures such as proteins at the atomic level. This work is vital in combating the growing threat of antibiotic-resistant bacterial infections and advancing cancer treatments.

"For me, it's about seeing humans thrive and reducing the suffering caused by illness," he explains. "I lost my grandmother to cancer, and I hope my work can spare someone else’s loved one from a similar loss."

Prestigious workshop with global experts

The "DLS-CCP4 Data Collection and Structure Solution Workshop," hosted by Diamond Light Source, offered Dr Jacobs an unparalleled opportunity to learn from leading experts in macromolecular crystallography. The workshop covered critical skills such as growing protein and DNA crystals, preventing degradation during data collection, and processing complex data. Participants also gained insights directly from the engineers and scientists behind the facility’s cutting-edge software and synchrotron technology.

“It was an incredible opportunity to learn from some of the brightest minds in the field,” says Dr Jacobs. “Not only did I acquire new skills, but I also forged new collaborations with potential research partners who can help take my work to the next level.”

The David Blow Bursary, which enabled Dr Jacobs to attend this workshop, is awarded to  African researchers conducting impactful macromolecular crystallography studies.

"This training has been transformative," he adds. "It is a fantastic experience for any aspiring researcher, and I’m grateful to have had the chance to learn from these experts. Many researchers who attend workshops like this go on to work at the Diamond Light Source itself. I am eager to see where this training will take me."

A vision for the future

As Dr Jacobs continues his research, he remains driven by the hope that his work will lead to life-saving advancements in healthcare. “I want my research to provide hope and solutions for individuals battling cancer and bacterial infections,” he says.

His achievements exemplify the transformative power of education, research, and collaboration, and his story serves as an inspiration to aspiring researchers across Africa.

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.
 
Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.
 
Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.
 
Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.
 
Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?
 
“Only exploration will give us these answers,” Dr Vermeulen said.
