Young researcher to jet out to UK

When Mamosa Ngcala jets out to the United Kingdom (UK) on 31 July 2018, she will not only be doing research and improving herself academically at the Durham University, but she will also put yet another feather in the growing research profile cap of the Qwaqwa Campus.

“I am looking forward to my study visit under the mentorship of Dr Steve Chivasa, my supervisor’s co-researcher in the Department of Biosciences at the renowned Durham University. This will enable me to grow academically as much as it will get me closer to concluding my research on climate change and food security,” said Mamosa, a master’s student in Science (Botany). Her supervisor is Dr Rudo Ngara.

“Going there will fast-track my research that looks at how food security can be enhanced in as far as growing sorghum is concerned. This study in Plant Biotechnology aims to identify heat responsive genes in sorghum, which is the fifth most important cereal crop in the world. The information obtained in this study will serve as fundamental knowledge regarding molecular responses of plants to heat stress and will be used in breeding programmes to develop crops that can tolerate high temperature stress conditions caused by climate change, thus resulting in high crop yield in agriculture as well as food security,” she said. She will be in the UK until 12 September 2018.

Mamosa has recently won the 3-Minute thesis competition for graduates that was part of the ‘Sorghum in the 21st Century’ international conference held in Cape Town.

Talking about this achievement, she said: “Going head-to-head with PhD students from all over the world gave me extra motivation and drive to do well, and I did. This goes to show that we can achieve whatever we put our minds to. Having to summarise my entire study in three minutes for a non-specialist audience, using one PowerPoint slide, was a challenge that had to be overcome,” said Mamosa. The conference was organised by the Collaborative Research on Sorghum and Millet and the University of Pretoria.

Mamosa graduated with distinction in Botany for her honours degree. She is a member of the Golden Key International Honour Society and Chairperson of the Postgraduate Student Council and is looking forward to advancing her studies to PhD level.

Einstein's gravitational waves as creative as Bach's music, says UFS physicist

Profile of the gravitational waves of the colliding black holes.

Prof Pieter Meintjes, Affiliated Researcher in the Department of Physics at the University of the Free State, welcomed the work done by the Laser Interferometer Gravitational-Wave Observatory (LIGO) science team.
 
For the first time, researchers from two of the American Ligo centres, in Washington and Louisiana respectively, observed gravitational waves directly, 100 years after Albert Einstein said they existed. "My study field in astrophysics involves relativistic systems. Therefore, Einstein's view of gravity is crucial to me. I consider the theory as the highest form of human creativity - just like the music of JS Bach. Over the past 100 years, the theory has been tested through various experiments and in different ways.
 
“The discovery of gravitational waves was the last hurdle to overcome in making this absolutely unfaltering. I am therefore thrilled by the discovery. It is absolutely astounding to imagine that the equations used to make the predictions about the gravitational-wave emissions when two gravitational whirlpools collide - as discovered on 14 September 2015 by LIGO - are basically Einstein's original equations that were published way back in 1916 - in other words, 100 years ago.
 
“The LIGO detectors have been operational since the early 1990s, but they had to undergo several stages of upgrades before being sensitive enough to make detections. LIGO is currently in its final stage, and is expected to function at optimal sensitivity only within a year or two. To be able to conduct the measurements at this stage is therefore a fantastic achievement, since much more funding will certainly be deposited in the project,” Prof Meintjes says.

The search for gravitational waves by means of the Square Kilometre Array (SKA) is one of the focus points in research by both Prof Meintjes and PhD student, Jacques Maritz. This involves the study of radio signals from pulsars that might show signs of effects by gravitational waves. They are looking for signs of gravitational waves. The gravitational waves discovered and studied in this manner would naturally vary much more slowly than the signal discovered from the two colliding gravitational waves.
 
The discovery will definitely provide renewed impetus to the Square Kilometre Array (SKA) Project to use the dispersion of pulsar signals, and to search for the impact of gravitational waves on signals as they travel through the universe. According to Prof Meintjes, the SKA will definitely contribute fundamentally to the Frontier research, which will provide a good deal of publicity for the UFS and South Africa, if significant contributions are made by local researchers in this field.
