Did you know that almost everything around you is being eaten by tiny organisms called microbes? These hordes of bacteria, archaea, and fungi have evolved to break down tough organic material into digestible nutrients. However, there is one material that almost no microbes can biodegrade: plastics. This is because most plastics have only been around since the 1950s, so most microbes haven't had time to evolve enzymes to digest them. As a result, plastics just turn into countless, tiny, indigestible pieces that pollute the environment. However, researchers have discovered microbes that may be able to take a bite out of this growing problem, creating super-enzymes that could break down plastics faster. By exploring the science behind microbes and biodegradability, you can learn how to become part of the solution to this global issue. Not only will you expand your knowledge, but you will also contribute to creating a cleaner, healthier planet.
As a society, we rely heavily on oil, but this addiction has led to environmental disasters like oil spills. However, nature has a way of cleaning up after us. Microbes, tiny bacteria that evolved to take advantage of oil and gas seeping from the sea floor, have been eating up oil spills for eons. In fact, a big bloom of microbes ate most of the 4.1 million barrels of oil spilt by BP's Macondo well in the Gulf of Mexico. These microbes are not only oil-eaters, but they also eat plastics, making them a potential solution to the Great Pacific Garbage Patch. Scientists are working on enhancing microbes' ability to eat oil and plastic, which could help us clean up our messes faster. Learning about these microbes and how they can benefit us is not only intellectually stimulating, but it also has practical implications for our planet's health.

Tardigrades have even been featured in popular culture, including an episode of Star Trek: Discovery, where they were used as a propulsion system for a spaceship. But while tardigrades may seem like science fiction, they are very much a real and fascinating part of the natural world. These tiny, water-dwelling creatures, also known as water bears or moss piglets, have been around for over half a billion years and have evolved some truly remarkable survival strategies. Tardigrades can survive in extreme environments that would kill most other organisms, including temperatures ranging from -272°C to 151°C, pressures six times greater than those at the bottom of the ocean, and even the vacuum of space. They can also survive dehydration, radiation, and exposure to toxins. Tardigrades achieve this impressive feat through a combination of strategies, including the ability to enter a state of suspended animation called cryptobiosis, which allows them to survive without water for years. One of the key factors that enable tardigrades to survive in such extreme conditions is their ability to repair their DNA. Tardigrades have a unique protein called Dsup, which protects their DNA from damage caused by radiation. This protein has even been shown to protect human cells from radiation damage. Dr. Thomas Boothby, a leading tardigrade researcher at the University of Wyoming, has discovered that tardigrades can also produce large amounts of unique proteins called tardigrade-specific intrinsically disordered proteins (TDPs) in response to desiccation. These proteins help protect the tardigrades' cells from damage and prevent them from drying out. Tardigrades are fascinating not just for their survival abilities, but also for their unique biology. They have a complex digestive system, a unique nervous system, and a fascinating reproductive system that involves the transfer of genetic material between individuals. By exploring the science behind these tiny creatures, we can gain a deeper understanding of the natural world and the amazing ways that living organisms can survive and thrive in even the most extreme conditions.

Plastic is a synthetic polymer that has completely changed our world. It is lightweight, durable, and can be molded into almost any shape. Unfortunately, plastic has saturated our environment, invaded the animals we eat, and is finding its way into our bodies. Plastic takes between 500 and 1,000 years to break down, yet we use it for things meant to be thrown away. 40% of plastics are used for packaging, and since its invention, we have produced about 8.3 billion metric tons of plastic. 79% of it is still sticking around, and a lot ends up in the ocean, where it outweighs all the fish. Microplastics, pieces smaller than 5 millimeters, have been found in honey, sea salt, beer, tap water, and in the household dust around us. While there is little science about the health risks associated with microplastics, it is safe to say that we have lost control over plastic to a certain extent, which is kind of scary. By learning more about plastic, we can take steps to reduce its impact on our environment and our health.
Water is one of the most fascinating substances in the universe. Every molecule of water on Earth has existed for billions of years, cycling through rocks, air, animals, and plants. Water doesn't follow the normal rules of chemistry, expanding when it freezes and floating on itself, enabling complex life to survive on our planet. Hot water freezes faster than cold, and water molecules can float upwards, against the force of gravity. This strange behavior has been very useful, allowing oxygen and nutrients to reach the edges of our brain and plants to move water from deep below the ground to nourish their leaves. Our solar system is drowning in water, and where there's water, there could be life. Learning about the properties of water can help students appreciate the remarkable nature of this colorless, featureless, and tasteless substance that breaks so many rules of chemistry.
