Maricél van Rooyen, Project Manager for Research Information Management System (RIMS) and Research Ethics Adviser in the Directorate Research Development (DRD) at the University of the Free State (UFS), is the Programme Coordinator for a first-of-its-kind Southern African Research and Innovation Management Association (SARIMA)/ COP webinar on Environment and Biosafety Research Ethics.

The University of the Free State (UFS) is playing host to a first-of-its-kind webinar on Environment and Biosafety Research Ethics later this month with Maricél van Rooyen, Project Manager for Research Information Management System (RIMS) and Research Ethics Adviser in the Directorate Research Development (DRD), playing a pivotal role.

The webinar, which is part of the Eastern Region Community of Practice (COP), is taking place on 20 August. The target market for this virtual workshop is Biosafety and Environmental Research Ethics Committee (REC) chairpersons and members, professionals including research management professionals, administrators, research compliance managers and advisers, and research directors in Southern Africa and beyond.

Van Rooyen will be the Programme Coordinator for this Southern African Research and Innovation Management Association (SARIMA)/ COP Research Ethics Webinar, while Prof Robert Bragg, chairperson of the UFS Environmental and Biological Research Ethics Committee (EBREC), will give a presentation on the establishment of an EBREC.

The UFS, Stellenbosch University and the University of the Witwatersrand, form part of the COP which is a SARIMA (Southern African Research and Innovation Management Association) initiative to assist and share research ethics questions between institutions to empower research management and ethics compliance. SARIMA assisted with the online hosting and advertising of the webinar.

Purpose of the webinar

“Environment and Biosafety Committees in South Africa are a new idea, and only a few institutions in the country have such a committee. The UFS and the other institutions that will present at the workshop, take a leading role because they have already registered committees in place. We want to share and assist with establishing and operating such committees,” says Van Rooyen.

According to her, the need for the webinar arises from the upsurge of research and innovation in biotechnology and related fields over the past two decades that has led to exciting new discoveries in areas such as the engineering of biological processes, gene editing, stem cell research, CRISPR-Cas9 technology, Synthetic Biology, recombinant DNA, LMOs and GMOs, to mention only a few.

These advances, however, have generated concerns about biosafety, biosecurity and adverse impacts on biodiversity and the environment, leading to the establishment of Research Ethics Committees (RECs) at Higher Education and Research Institutions dedicated to reviewing research with implications for biosafety and the environment.

These EBRECs are in the early stages of their establishment and formalisation in South Africa, and there is much uncertainty about their composition, scope, procedures of decision-making and the principles that should guide their deliberations and assessments.

Leading the charge

The UFS took the lead in South Africa in ensuring international ethical compliance in this extended area of research, by establishing its own Environmental and Biological Research Ethics Committee (EBREC) six years ago. The UFS EBREC is one of only two such ethics committees at a South African university that combines the biosafety committee with environmental and biological research ethics to ensure ethics compliance in these fields.  The initiative started with Van Rooyen and her RIMS EthicsTeam, (Willem Kilian and Amanda Smith). The university is again taking charge with this webinar, which is a first of its kind.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
