A seven-planet parade, a gathering of global scientists, and an expo where lab technology meets opportunity
By the time you read this, the seven-planet alignment will have already happened. The term 'planet alignment' or 'planet parade' has been mentioned a lot in 2025 so far. January 2025 saw six planets in the night sky all at once: Venus, Mars, Jupiter, Saturn, Uranus and Neptune.
Understandably, the hype and anticipation surrounding this event was huge, with many stargazers getting excited at the prospect of seeing a multitude of Solar System worlds in the same view.
Then, everyone started talking about the fact that Mercury will emerge into the evening sky and will join the planet parade in late February 2025, making for a seven-planet alignment. Professional astronomers are even telling us a seven-planet alignment like this won't be visible again until 2040.
"Friday 28 February is the special date, with seven planets visible in the sky - if the night is clear," says Associate Professor of Physics David Armstrong at The University of Warwick, UK. "This 'great planetary alignment' won’t happen again until 2040, as it needs all the planets to be on the same side of the Sun."
It's not surprising, or even uncommon, for multiple planets of the Solar System to be visible in the sky at once. Nor is it surprising for multiple planets to be visible in a line. The caveat, however, is that the line in question is a curved line that stretches across the sky and is known as the ecliptic. The ecliptic is the apparent path the Sun traces across the sky, and is a result of our Solar System having formed from a disc of material surrounding our newborn Sun.
All the planets – Earth included – orbit in the same plane around the Sun, and so the planets occupy the same area of the night sky that the Sun occupies during the day. The planets are always found more or less along this imaginary line, and this is one of the best ways of telling whether you're looking at a planet or a star in the night sky.
To add to the excitement of things happening early in the year, another significant event took place, whereby global scientists assembled in the Kruger National Park. Scientists, researchers, and Protected Area Managers from around the world gathered at the 22nd Annual Savanna Science Network Meeting which took place from 3 – 6 March 2025 in Skukuza. Under the theme “reimagining Conservation: Healthy, Sustainable, Climate-resilient Savannas that Benefit People”, this internationally
Annual subscription R452,00 for 6 issues (SA

acclaimed event brought together leading scientists, researchers, conservationists, and policymakers to address critical challenges facing savanna ecosystems and the communities that depend on them.
The park hosted 230 delegates representing 91 different scientific and conservation organisations from 21 countries. Many topical issues in ecological and social sciences were covered during the four days’ presentations and posters. There was a range of sessions covering various topics and these included:
• Large and largely unexpected patterns in vegetation overtime Savannah conservation in the age of artificial intelligence From source to sea: integrated management of freshwater ecosystems
Building sustainable connections to natural and cultural heritage inside parks
• Walking the mammalian tightrope – balancing costs and benefits
The close interactions between academics and park authorities facilitated by this meeting are key to promoting pro-active evidence-
based decision-making and directing research to address priority conservation management needs. The meeting has always valued capacity building, and as such students share the platform with world-renowned savanna scientists from across the globe.
The idea for the Savanna Science Network Meeting came about when a small group of scientists working on river-related issues in KNP, reflecting on the impacts of the 2000 flood event, started thinking that a small meeting could be held annually to share research findings with park management. The scope and participation of these meetings grew quickly to include Savanna-related research and delegates from many countries and organisations. This meeting is now considered the premier international savanna science conference covering socio-ecological research taking place in savannas across the globe. The conference format allows for dialogue and discussion on ecological science and conservation matters, both formally and informally in a spectacular venue, shaping our collective understanding and seeding future research collaborations and projects to address key knowledge gaps.
And lastly, something to look forward to: analytica Lab Africa, the only trade show in South Africa for the laboratory technology, analysis, biotechnology and diagnostics sectors, will welcome the return of many regular exhibitors and the arrival of a number of firsttime exhibitors when it gets underway in Johannesburg from 8 – 10 July. Don’t miss it!
So many exciting things and feel-good moments for the start of 2025.
Here’s to many more!

analytica Lab Africa, the only trade show in South Africa for the laboratory technology, analysis, biotechnology and diagnostics sectors, will welcome the return of many regular exhibitors and the arrival of a number of first-time exhibitors when it gets underway in Johannesburg in July.
Avisha Desai, Business Unit HeadConsumer & Capital Goods at Messe Muenchen India (MMI) says: “At the last analytica Lab Africa in 2023, 107 top local and international exhibitors showcased over 230 leading brands. In 2025, we are excited to welcome back leading industry sponsors and exhibitors, as well as firsttime exhibitors such as Promega Scientific Solutions of the UAE, and local exhibitors XTEMP, BennyZA and Gibbs Technologies. The repeat participation of many of our exhibitors is testament to the importance and impact of the event, while the arrival of new exhibitors is an indicator of our ongoing growth.”
“analytica Lab Africa is certainly the trade show ‘where lab technology meets opportunity’, offering a unique forum for industry stakeholders to discover the latest scientific and laboratory innovations and network with their peers,” she says.
Robin Fernandes, Business Unit Head –Capital Goods at MMI notes that the co-location of analytica Lab Africa with IFAT Africa amplifies the benefits and reach for exhibitors and visitors. IFAT Africa is the ultimate showcase of technologies and
solutions for water, sewage, refuse and recycling for the sub-Saharan African market. Together, the shows bring together over 8,000 local and international visitors across a broad, overlapping value chain including testing and analysis, environmental technology, food and beverage, agriculture, pharmaceuticals, life sciences, water and waste management and recycling solutions.
Prominent sector participants including Lasec, Metrohm, Labotec, Shimadzu, Hanna Instruments, Wirsam, Perkin Elmer, Sartorius, amongst others have signed up for the 2025 event instalment.
Lasec, the ultimate solution provider for laboratories across Africa, will showcase 17 international suppliers and a broad range of solutions and innovations at its pavilion at analytica Lab Africa in Johannesburg in July this year.
The Lasec pavilion is a major drawcard at analytica Lab Africa, with exhibition space at its pavilion oversubscribed, and delegates travelling from across Africa for a rare opportunity to get hands-on access to the latest laboratory furniture, equipment and software solutions.
Lasec Director Delphine Darling says Lasec pavilion at the trade show will feature suppliers of products and solutions across the laboratory workflow, with product demonstrations and talks throughout each day.
She says: “Visitors to the pavilion will benefit from informative interactive talks, hands-on demos, and literally explosive demos on chemical safety. They will also get a first-hand look at some suppliers who are new to analytica Lab Africa, including innovative products for food and beverage and packaging quality control in the FMCG industry.”
Lasec Product Portfolio Manager Kylie Davis says: “Lasec has grown its pavilion at analytica Lab Africa over the years. This year we had such an excellent response from previous suppliers that we had to
work on a first-come, first-served basis for supplier participation. Many suppliers wanted to come again, and many new suppliers wanted to participate, so we were oversubscribed for the space that we had available in 2025.”
In line with a growing focus on AI and data-driven decision making, Lasec will also introduce a Laboratory Information Management System (LIMS) partner at analytica Lab Africa this year.
Davis says: “LIMS can basically help you to run your lab more effectively, improving sample flow, and using data more effectively for decision-making. Where LIMS was once the preserve of highly specialised labs, it is now becoming more accessible and essential for most labs. At analytica Lab Africa, we will have a biotechnology-focused laboratory setup connected to a mock LIMS system, so visitors can see how working LIMS can function.”
Davis adds that the co-location of analytica Lab Africa with IFAT Africa, the leading trade fair for water, sewage, waste, and recycling, is highly beneficial for exhibitors and visitors to the trade shows.
She says: “Lasec supplies products that assist with waste management, so at the last co-located event, we had numerous visitors to IFAT Africa visiting our pavilion too.”
“Environmental impact is a priority within the laboratory space, and apart from waste management equipment, we also have a number of innovations that can support better use of consumables in the lab and the cutting down of waste in the laboratory industry. So, it is a very relevant co-location.”
Darling notes: “As the ultimate solution provider for laboratories, Lasec works to fulfil a complete workflow. At analytica Lab Africa, our biotech lab showcasing the furniture that our team manufactures, as well as the range of products we can offer for various types of labs. We will also highlight our application specialists who assist customers in getting the maximum out of their equipment, and the expertise of our service department.”

External factors such as temperature fluctuations, air currents, electromagnetic interference, and vibrations can all have an impact on the accuracy of the analytical balance. It is important to keep the analytical balance in a controlled environment to minimise these factors and ensure accurate readings. By understanding and controlling these external factors, users can ensure that the analytical balance provides reliable and accurate measurements for their research or testing needs. Being aware of these environmental elements might help you to set up a good start.
1.Temperature and humidity
Temperature and humidity are two critical environmental factors that can significantly impact the weighing results on analytical balances.
Temperature: It is important to operate analytical balances within a stable temperature range specified by the manufacturer to minimise the effects of temperature on the weighing results. Using a temperaturecontrolled environment or placing the balance away from sources of heat or cold drafts can help maintain stability and consistency in measurements.
Humidity: Inconsistencies in humidity can lead to fluctuations in readings and compromise the accuracy of measurements. High humidity will
cause the weighing sample to absorb moisture and change in weight. Keeping the laboratory at a controlled humidity level and storing balances in a dry environment can help prevent humidity-related issues and ensure stable weighing results.
2. Air currents
Air currents can have a significant impact on the stability and accuracy of an analytical balance.
3. Magnetic fields
Magnetic fields can also cause instability in an analytical balance, as they can interfere with the proper functioning of the load cell. The analytical balance uses an MFR load cell (electronic Magnet Force Restoration) which is very sensitive to external magnetic fields.
4. Electrostatic charges
Static electricity can accumulate on objects, including sample materials, containers, or even the balance itself.
When static charges build up, they can create imbalances in the weighing system, leading to fluctuations in readings and hindering the ability of the balance to provide accurate measurements.
To mitigate the impact of static electricity on the stability of an analytical balance, it is important to take preventive measures.
Precision vacuum measurement for industry & laboratory
In industries where precision vacuum measurement is critical, Thyracont digital vacuum gauges provide exceptional accuracy, improving production efficiency and reducing errors. Their advanced design minimises downtime, prevents equipment failures, and enhances process control, ensuring costeffective and reliable operations.
Vacuum ranges & applications
Thyracont gauges measure vacuum levels across multiple industries:
• Rough vacuum (atmospheric to 1 mbar): Industrial processes, packaging, HVAC, and laboratories. Uses Piezo and diaphragm sensors
Fine vacuum (1 to 10⁻³ mbar): Freeze drying, vacuum drying, and coatings. Uses Pirani sensors
High vacuum (10⁻³ to 10⁻⁷ mbar):
Semiconductor manufacturing, research labs, and microscopy. Uses Pirani and ionisation sensors
• Ultra-high vacuum (10⁻⁷ to 10⁻¹² mbar): Particle accelerators, space simulations, and advanced physics research. Uses ionisation sensors
• Extreme ultra-high vacuum (below 10⁻¹² mbar): Specialised scientific and space applications. Uses ultra-high vacuum ionisation sensors

The WOB-L Pump 2585 model offers:
1. Economical and oil-free operation: It operates without oil, reducing maintenance fuss
2. Lightweight and compact design: makes it ideal for standard-duty applications
5. Vibration
Vibration can be another factor that contributes to instability in an analytical balance. In a laboratory environment, various sources of vibration such as nearby equipment, foot traffic, or even factors external to the laboratory can disrupt the balance readings and affect the accuracy of measurements. Even the smallest of movements can make it challenging to obtain precise results on highresolution instruments.
6. Heat radiation
Heat radiation can also be a factor that causes instability in an analytical balance. When heat radiation, including human body heat, affects an analytical balance, the temperature variations can create air currents that disrupt the balance and introduce inconsistencies in the readings.
7. Sample volatilisation and moisture regain
The temperature of the sample being weighed can also be a critical factor that contributes to instability in an analytical balance. When the sample temperature changes, it can impact the mass or density of the sample, leading to variations in the weight measured by the balance.
8. Aerostatic buoyancy
Air buoyancy, or the force exerted by air or gas
on objects immersed in it, can also be a significant factor that contributes to instability in an analytical balance. Changes in air density, such as fluctuations in temperature or altitude, can impact the apparent weight of objects being weighed on the balance.
User-friendly and connected
Designed for ease of use, Thyracont gauges feature intuitive digital displays, real-time data logging, and seamless calibration. With USB, Bluetooth, and RS-232/RS-485 connectivity, they integrate effortlessly with industrial systems for remote monitoring and automation.

One of South Africa’s leading producer responsibility organisations (PRO), Petco, has bid farewell to industry stalwart Cheri Scholtz and welcomed a new Chief Executive Officer, Telly Chauke, as of 1 January this year.
Chauke replaces long-standing CEO Scholtz, who has helmed the organisation since its incorporation in 2004 and led its successful transition from voluntary to government-legislated mandatory extended producer responsibility (EPR), which came into effect in 2021.
The EPR regulations require that producers in the paper and packaging sector - brand owners, retailers and importers - discharge their obligations individually or collectively by joining a PRO to take responsibility for the full lifecycle of their post-consumer packaging, so that it does not end up in the environment or landfill.
Experienced sustainability specialist Chauke joined Petco as CEO designate in September last year, beginning a strategic, planned leadership handover for one of the country’s longest standing and most successful PROs. She is the former chief sustainability officer for the Coega Development Corporation and was the specialist on environment, climate change and sustainability policies for the South African Local Government Association (SALGA) for 10 years prior to that.
“We are exceptionally pleased to have someone of Telly’s calibre on board in this role, as she brings a wealth of experience in navigating the public policy space,” says Scholtz. “But, more than that, as a climate and environmental scientist, she brings a unique additional skill set to the role. I leave Petco in very capable hands.”
Scholtz was part of the industry-led team that kickstarted a voluntary mechanism for collection and recycling of PET in South Africa. The result was Petco, which developed a sustainable collection and recycling funding
model almost two decades before the landscape of post-consumer packaging was legislated by the government.
During Scholtz’s tenure, Petco surpassed its medium-term goal to collect and recycle 50% of post-consumer PET beverage bottles by 2015. Collection for recycling grew from approximately 10 000 tonnes per annum to over 90 000 tonnes, which represented an increase of more than 600% when considering the growth in the volume of PET placed onto the market during this time.
The most recent audited results show that Petco achieved 98% of legislated targets set by the Department of Forestry, Fisheries and the Environment’s (DFFE) for these products by volume.
In 2023, Petco achieved the required 64% collection rate and exceeded the 58% (60% achieved) recycling rate for post-consumer PET beverage bottles placed on the market by its members. It also achieved 80% of the legislated recycling target for its new EPR
scheme for liquid board packaging (LBP), and followed this with 100% of targets met in 2024.
“I’m really proud that I was able to bring LBP into Petco, and I think that was incredible validation that the Petco model can work for packaging materials other than PET,” says Scholtz.
She says building a sustainable value chain has been critical to the organisation’s success so far. “We’ve attended to the enduse market, created value for collectors and buy-back centres, encouraged the development of recycling capacity and capability, and then worked to unlock the feedstock through enabling collection. I believe this balanced approach will stand Petco in good stead for continued success and resilience in the years to come.”
Chauke says she looks forward to guiding members towards meeting their EPR targets and broader strategic sustainability goals. “An enabling public policy regime and a healthy relationship between industry, the
government and consumers are core to successful EPR; and I look forward to steering Petco in maintaining these relationships for the benefit of our members and recycling partners,” Chauke adds.
Petco currently counts brand owners such as Unilever, Tiger Brands, Twizza, Coca-Cola and PepsiCo, and retailers Pick ’n Pay and Woolworths among its members.
“Coming from a governance and sustainability background, I understand the rand value of being compliant both in terms of public policy and the broader global ESG [environmental, social and governance] reporting metrics. So, I’m excited to contribute and to build on the solid foundation of Cheri’s 20 years of stewardship.”
Speaking on behalf of the Petco board of directors, chairman Greg Morse says, “We extend our heartfelt gratitude for Cheri’s invaluable contribution to EPR in South Africa, and as she retires, we are confident that she will remain a committed ambassador of not only Petco but the packaging sector indefinitely. Her knowledge, leadership and pioneering spirit have seen Petco grow to become a nationally compliant and globally relevant PRO.”
Morse also welcomed the new CEO, assuring Chauke of the board’s support going forward. “In selecting and appointing Telly to the role of Petco CEO, the Board is assured of her competence and ability to lead Petco and sustain its legacy of positive impact and meeting EPR targets. Telly will enjoy our full support and guidance as we enter the next period of mandatory EPR.”
