Insects on the menu
Beetle juice and bug flour; Drs Ismari van der Merwe and Cariena Bothma are researching the possibility of a high-protein diet consisting of insect ingredients.

You’ve just had a tasty milkshake made from grasshopper juice, now for a light snack. Your choice: Salty cricket cookies or a deep-fried ant delight?

One of these days the above delicatessen may just find its way to your local restaurant menu if Drs Ismari van der Merwe, Cariena Bothma, both lecturers in the Department of Consumer Science, and their enthusiastic team of students have their way. Insects as food are rich in protein, often tasty, and having them on a menu is not as far-fetched as you may think. After all, we know what culinary delights mopani worms – and yes – cooked land snails (enjoyed as escargots) have become over the years.

 

Cricket smackerals

 

When Dr Van der Mewe explains the benefits of her team’s vision for a high-protein diet consisting of insect ingredients (cricket flour as an example), one becomes aware that this could be the solution to a myriad of problems. Insects eat much less than our regular menu items such as cows (beef), sheep (lamb chops) or pigs (pork). Insects as an alternative diet will reduce the negative impact that larger animals have on the environment and greenhouse gases. Insects have faster life cycles and it takes less effort and space to breed and feed them.

“Ugh! Ick! Disgusting,” you might think. But picture the taste lab where volunteers are given regular chocolate cookies made with regular flour, and then asked to compare it with cookies made from cricket flour. Dr van der Merwe assures me that most people will be unable to distinguish between them, often even preferring the cricket smackerals.

 

Heathy alternative

 

Insect breakfast cereals, granola, and snack food is a real and viable solution for the developing world where food is scarce, and hunger is a real issue. But is it healthy? Dr Van der Merwe assures me that during the process of ‘bug to flour’, they are addressing the main concern: micro-organisms that might be detrimental to health. Once the insects or processed insect by-products arrive on your plate, it’s a healthy high-protein alternative that might become the next revolutionary diet.

So, stand aside Atkins, beware Banting, and be gone Gluten-free – there is a new diet on its way to the menu. Brace yourself for beetle juice and bug flour: a diet full of proteins, fat, energy, and essential amino acids.

Boyden Observatory turns 120

The Boyden Observatory, one of the oldest observatories in the Southern Hemisphere and a prominent beacon in Bloemfontein, recently celebrated its 120th year of existence.

This milestone was celebrated by staff, students, other dignitaries of the University of the Free State (UFS) and special guests at the observatory last week.

“The observatory provides the Free State with a unique scientific, educational and tourist facility. No other city in South Africa, and few in the world, has a public observatory with telescopes the size and quality of those at Boyden,” said Prof. Herman van Schalkwyk, Dean of the Faculty of Natural and Agricultural Sciences at the UFS.

The observatory, boasting the third-largest optical telescope in South Africa, has a long and illustrious history. It was established on a temporary site on Mount Harvard near the small town of Chosica, Peru in 1889. Later it was moved to Arequipa in Peru where important astronomical observations were made from 1891 to 1926. “However, due to unstable weather patterns and observing conditions, it was decided to move the Boyden Station to another site somewhere else in the Southern Hemisphere, maybe South Africa,” said Prof. Van Schalkwyk.

South Africa's excellent climatic conditions were fairly well known and in 1927 the instruments were shipped and the Boyden Station was set up next to Maselspoort near Bloemfontein. Observations began in September 1927 and in 1933 the new site was officially completed, including the 60 inch (1.5 m) telescope, which was then the largest optical telescope in the Southern Hemisphere. This telescope was recently refurbished to a modern research instrument.

The observatory has various other telescopes and one of them, the 13" refractor telescope, which was sent to Arequipa in 1891 and later to Bloemfontein, is still in an excellent condition. Another important telescope is the Watcher Robotic Telescope of the University College Dublin, which conducts many successful observations of gamma ray bursts.

“In the first few decades of the twentieth century, the Boyden Observatory contributed considerably to our understanding of the secrets of the universe at large. The period luminosity relationship of the Cepheid variable stars was, for example, discovered from observations obtained at Boyden. This relationship is one of the cornerstones of modern astrophysics. It is currently used to make estimates of the size and age of the universe from observations of the Hubble Space Telescope,” said Prof. Van Schalkwyk.

“The Boyden Observatory contributed to the university’s astrophysics research group being able to produce the first M.Sc. degrees associated with the National Space Science Programme (NASSAP) in the country and the Boyden Science Centre plays an important role in science and technology awareness of learners, teachers and the general public,” said Prof. Van Schalkwyk.

The Boyden Science Centre has also formed strong relationships with various institutions, including the South African Agency for the Advancement of Science and Technology (SAASTA) and the Department of Science and Technology. The centre has already conducted many different projects for the Department of Science and Technology, including National Science Week projects, as well as National Astronomy Month projects. It also serves as one of the hosts of SAASTA’s annual Astronomy Quiz.
