FOREWORD A reflection of 2015 I read somewhere that; “A calm sea does not make a skilled sailor”. This year I have come to believe that saying. The year 2015 has been a very busy academic year for most, I included. This year I have had to juggle Physical Sciences, Life Science, Mathematics and Accounting as my majors. I must say for a learner in grade 10 up until grade 12, to be able to manage that much requires a lot of courage and dedication. I am currently a grade 10 learner and confident that I will be in grade 11 in 2016. High school comes with a lot of challenges but it is important that one never forgets where they are coming from and where they are going, because if you do, then it means you do not have any goals. One of the biggest challenges you come across in high school is being able to choose the right subjects and sticking with them throughout. It is a well known fact that a lot of young people are not venturing into the Maths and Science fields, even Minister Naledi Pandor has taken up the initiative to launch programmes that will encourage and excite young people to venture into these fields. Issues like that need to be taken seriously. Another of the

LETTER FROM THE EDITOR

Managing Editor • Evans Manyonga editor@sciencestars.co.za

2015 in Perspective

Graphic Designer • Cinzia-Joey Swartz

It seems like yesterday when we were celebrating the new year. Today as I write this, the end of the year is close. The Science Stars team has been hard at work all year. From attending the Science Festival earlier in the year to the valuable endless science expos and events across the country, we can certainly say it has been a productive year. In terms of Scifest we are looking forward to the 2016 edition. The 20th edition of South Africa’s National Science Festival, will take place in Grahamstown, Eastern Cape from 2-8 March, and the theme will be “A matter of time”, exploring the creation, measurement, depiction, experience and end of time. In 2015 we covered a number of topics. Among these were Health and medical science, Women in Science, Nanotechnology, Mathematics and our Scifest/Bloodhound issue. We explored a lot of concepts and learnt a few lessons. Out of the many aspects in science in South Africa, one personally stood out for me. This is because it will help a lot of people and more importantly that aspect puts SA on the world map while ensuring the country gave the world a medical breakthrough. The Health and Medical Science sector in SA has been growing in leaps and bounds. SA has been traditionally strong in making advances in this sector. Figures like Dr Christian Bernard put SA on the map through their world changing work. In March 2015 South African scientists announced the world’s first successful penis transplant, helping a 21-year-old who suffered an amputation following a botched traditional circumcision three years ago. Professor Andre van der Merwe, head of Stellenbosch University’s Division of Urology, announced details of the “ground-breaking” operation at Tygerberg Hospital in Bellville, Cape Town. The nine-hour operation involved the attachment of a penis taken from a donor who had died. The recipient of the donor organ made a full recovery and is now fully functional. This was a world first and certainly put SA on the world map once again. Our final issue looks at trending science in 2015. We look at some of the famous aspects Science Stars Magazine covered and some emerging trends we just couldn’t ignore. Enjoy it, critique it and above all learn something from it.

Awareness and information about water quality in rivers is an important part of improving that quality, and the Department of Science and

DST

AND WRC

LAUNCH MOBILE

APP

Technology (DST) and the Water Research Commission (WRC) have partnered to support the development of a mobile app called miniSASS that helps to monitor water quality. The easy-to-use tool, developed jointly with m-Lab (a mobile solutions laboratory and startup accelerator), enables ordinary people and communities to assess the health of streams and rivers, learning about and contributing to the science of water monitoring. Launched in Johannesburg on 18 September, the application allows users (many of whom are school children), to locate the nearest stream or river quickly, and see what the current river health is. The user collects a sample of macro-invertebrates and other small river creatures from the water, and the creatures found give the user a measure of the general river health and water quality of the particular river. The app also shows the user whether the stream has existing river monitoring sites. The miniSASS monitoring system is linked to a Google Earth system, and the Google Earth map allows users to see, at a glance, how healthy the streams and rivers around the country are. The observations that users provide will be used to fill out the map. Speaking at the launch, Chief Director; Sector Innovation and Green Economy, Mr Isaac Maredi explained that the Department was exploring the potential of mobile technologies to improve the life of ordinary people and to support service delivery in several areas. The first version of the application can be downloaded from http://minisass.mobi or www.minisass. org using any android device with Internet connection (e.g. tablets and cellphones).

WOMEN EMPOWERED Young women scientists urged to stay the course

“post-docs” to spend time in South Africa to further their research careers and to assist with undergraduate training, especially in critical areas in which we lack capacity. The Minister said the recent launch of the SARChI 42 initiative (42 new female research Professors) has altered the gender imbalance in the prestigious research professor’s programme. “Nearly half of our 200 research professors are now women,” said Minister Pandor. While the country has put several measures in place to ensure local gender equity, it is playing a similar role in southern Africa and Minister Naledi Pandor

SCIENCE NEWS

SCIENCE NEWS The country’s persistent heat wave of maximum temperatures of close to 40 degrees Celsius has caused an enormous amount of harm in food production. The South African Medical Association (SAMA) says South Africa is likely to experience water related diseases. The death of Nola, the northern white rhino at the San Diego Zoo on Sunday made international headlines. Nola was one of only four northern white rhinos left on Earth.

Jill Farrant, a professor of Molecular and Cell biology at the University of Cape Town, is leading a global research into developing crops that resemble the extraordinary survival skills of “resurrection plants”.

Air Zimbabwe flight between the national capital of Harare and Victoria Falls made air travel history by being the first ever flight in Zimbabwe to have an all-female flight deck crew. The plane was piloted by Captains Chipo M. Matimba and Elizabeth S. Petros. After 20 years of collecting fossils, researchers finally have enough fossils to put together a complete picture of a 14-tonne creature from the sauropoda group of dinosaurs, characterised by their small head, long neck, long tail and elephant-like gait. The Minister of Science and Technology, Naledi Pandor, inaugurated into office the Science, Technology and Innovation (STI) Institutional Landscape Panel. It has been appointed to review the South African STI landscape.

A team of scientists led by Kim Lewis from Northeastern University have identified a new antibiotic called Teixobactin, which kills some kinds of bacteria by preventing them from building their outer coats. Teixobactin is resistant to resistance.

According to scientists as of September 2015, there is water flowing on Mars. This is evident due to dark streaks that appeared on the surface of the Red Planet. Although flowing water has always been a possibility due to the visibility of the dark streaks.

A type of stainless steel mesh that repels oil from its surface has been discovered. The Ohio State University scientists explained that other liquids like water can pass through the mesh easily, but oil cannot pass through.

Study tips

Don’t procrastinate!

Make flashcards, use acronyms, sing jingles - anything to help you remember.

Exercise and eat correctly to combat stress. Use tables, flowcharts and figures - pictures can help you remember facts.

Get up a little earlier on the morning of an exam - it will allow you time to have a proper breakfast and you will feel calm when you arrive at your exam venue.

Create a study environment free from clutter and distractions.

If the workload is too big, join a study group. But make sure you actually study.

Get a decent night’s sleep. It helps with your concentration.

Go over as many past papers as you can.

Don’t postpone difficult topics when studying tackle the hard bits first.

Good luck!
