TouchScience Africa Exploring both Africa and Global science frontiers.

Insightful conversations
Where research meets real life, science made simple, stories made real
TouchScience Africa is a science communication initiative dedicated to highlighting and promoting African-led innovations in agriculture, climate change, conservation, health, and biotech, etc. Our mission centers on making science accessible and impactful by bridging the gap between research, policy, and everyday life across the continent. TouchScience Africa disseminates its content through various channels, including LinkedIn, Facebook, Instagram, X, and YouTube. Through these platforms, TouchScience Africa aims to foster a greater understanding of science and its role in driving sustainable development and health improvements across the continent.

Wildlife should never have to eat our waste.

When an elephant consumes plastic, the problem didn't begin with the elephant. It began with what humans left behind.

Research in India has found plastic and other human-generated waste in elephant dung, showing how poor waste management around wildlife habitats can pose a wildlife health problem.

Science teaches us something important:

Pollution doesn't stay where we leave it.

It moves through animals, soil, water, and ecosystems.

Protecting wildlife, therefore, isn't only about protecting animals inside forests. It also means managing what happens around those forests.

What if every waste-management plan near a wildlife habitat included one simple question:

Could this waste become an animal's next meal?

Madagascar is making a major conservation move.

Rainforest Trust has announced a $10 million commitment to conservation in Madagascar, supporting the country's efforts to protect its extraordinary biodiversity and advance its 30×30 goal, conserving 30% of its lands and waters by 2030.

Why does this matter?

Madagascar is one of the most biologically unique places on Earth, with most of its plants and animals found nowhere else.

But conservation isn't just about protecting wildlife. It is also about science, communities, local leadership, and the financing needed to keep ecosystems protected.

The bigger question is: Can conservation finance move fast enough to protect Africa's remaining biodiversity?

From a plain copper sheet to an LED circuit.

What looks like a simple sheet of metal can become the pathway that makes an electronic device work.

Through chemical etching, unwanted copper is removed, leaving behind carefully designed conductive traces. Components can then be mounted onto the board to create a functioning circuit.

The science is fascinating, but so is the bigger lesson:

Manufacturing is knowledge made physical.

When countries develop the skills to transform raw materials into finished components, they create opportunities for jobs, local industries, and technological independence.

As countries like India expand their manufacturing capabilities, an important question for Africa is:

What electronic components could we learn to make locally instead of importing everything?

What if a familiar root crop could become something completely different?

Sweet potato can be processed into flour and blended with wheat flour to make noodles, an example of how food science creates new value from crops we already grow.

Depending on the variety and processing, sweet potatoes can contribute fiber, β-carotene, and other nutrients to composite foods. Research has shown increased β-carotene and fiber in noodles enriched with sweet-potato flour.

But the opportunity goes beyond nutrition.

Processing can create new markets for farmers, reduce post-harvest losses, and open opportunities for local food businesses.

What other African crops could we transform into everyday foods instead of selling them only in their raw form?

⚠️ Disclaimer: The video may be AI-generated or edited, so the exact practice shown cannot be independently confirmed. However, the farming principle behind it is real.

Why would a farmer put straw into a fish pond?

It can be part of an integrated farming approach, in which crop residues are treated as resources rather than waste.

Organic materials can provide surfaces for microorganisms and contribute to nutrient cycling when properly managed.

The bigger lesson?

Waste from one part of a farm can become a resource for another.

Could African farmers adapt more integrated systems like this to reduce waste and make better use of available resources?

⚠️Disclaimer: This viral video may be AI-generated. While similar behavior may occur in nature, the specific interaction shown in this video should not be taken as authentic wildlife footage.

But the real science behind it is fascinating. 🐦🦏

Oxpeckers really do feed on ticks and other material found on large African mammals. But their relationship with these animals is more complicated than simply “cleaning” them. Scientists have found evidence of both benefits and potentially harmful behavior.

Nature is rarely as simple as a viral video makes it look.

That is why we must learn to question what we see and verify before we share.

What if your spoon didn’t become waste after the meal?

This edible spoon from India turns an everyday disposable item into something that can be eaten or allowed to biodegrade.

It’s a simple idea, but the science behind it is interesting: What materials can we use to make products that perform their job without creating a long-lasting waste problem?

The bigger lesson is about designing with the end in mind.

Could African innovators rethink everyday products this way?

What is one disposable item you think we should redesign?

Sometimes innovation is already in the community.

Long before “sustainable agriculture” became a popular term, farmers were finding ways to manage weeds, reuse local materials, and work with the environment around them.

The science lesson? Local knowledge is a form of observation, experimentation, and adaptation.

But the next step is important: document it, test it, improve it, and combine what works with modern science.

What traditional African farming practices do you think deserve a closer scientific look?

If there are no paddlewheels in the pond, where does the oxygen come from?

That question opens the door to an important piece of aquaculture science.

Shrimp need dissolved oxygen to survive, but managing oxygen isn't simply about having a paddlewheel. It is about how oxygen enters the water, how water circulates, how oxygen is distributed, and how quickly shrimp and microorganisms are using it.

Different systems can use different approaches to aeration and water movement, including diffused air and other circulation technologies. The goal is the same: maintain a healthy oxygen environment throughout the pond.

This matters because aquaculture is ultimately about managing a living ecosystem.

The bigger question for us is:

Can we design aquaculture systems that use less energy while still giving aquatic animals the oxygen and water quality they need?

Sometimes innovation isn't about adding more equipment. It is about better understanding the system.
