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.
Have you ever wondered how we know how old something is? For trees, we count the rings, and for people, we ask for their birth certificate. But what about fossils? Well, fossils have their own internal clock, and scientists can read it by looking at the ratio of two different types of carbon atoms. Carbon dating works for fossils up to about 60,000 years old, and by measuring the ratio of carbon 14 to carbon 12, we can determine how many thousands of years have passed since the animal died. Learning about carbon dating and other scientific methods can help us better understand the world around us and our place in it. So, why not explore this fascinating topic further and discover the secrets that fossils can reveal?
Oxybenzone in sunscreens is disrupting coral reefs, leading to international bans. Scientists are now exploring eco-friendly alternatives like mycosporine-like amino acids (MAAs) found in ocean organisms that offer potent UV-absorbing shields, antioxidants, and anti-inflammatory properties. However, regulatory hurdles and environmental concerns remain. Discover the latest research and innovations in the search for safer and more effective sunscreens.
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.
Want to know the secret to drought-resistant plants? A group of researchers from Yale, Bates College, University of Maine, Haverford College, and other institutions have discovered that plants with more complex water transport structures are more resistant to droughts, increasing their chances of survival and passing on this trait to their offspring.
Understanding the science behind the changing colors of leaves in the fall is not only fascinating but also important for our understanding of the natural world around us. The process is triggered by less daylight, causing the old chlorophyll to disappear and yellow and orange pigments to become visible. The intensity of the colors is connected to temperature, and the drier autumn weather triggers a hormone telling the tree to drop its leaves. Evergreens have a waxy coating and contain a chemical like anti-freeze to survive the winter. By learning about these concepts, students can gain a deeper appreciation for the natural world and develop critical thinking skills. Additionally, understanding the science behind fall leaves can inspire students to explore other scientific topics and engage in self-directed projects.

Half a million barrels of DDT waste dumped in the ocean in the 1940s and '50s remain in startlingly high concentrations, spread across a wide swath of seafloor larger than the city of San Francisco. Recent studies have linked the presence of this once-popular pesticide to an aggressive cancer in sea lions, and significant amounts of DDT-related compounds continue to accumulate in California condors and local dolphin populations. With a $5.6-million research boost from Congress, scientists and environmental nonprofits are racing to figure out the extent of the contamination lurking 3,000 feet underwater.
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.
Are you a plant lover who also cares about the environment? Then you'll definitely want to read this article from Smithsonian Magazine about Neoplants, a Parisian start-up that is creating genetically modified plants that filter harmful chemicals out of the air. Their first product, the Neo P1, is a bioengineered version of the popular pothos houseplant that can capture and recycle dangerous air pollutants commonly found in homes. But can these plants really make a difference? Read on to find out.

The Permian-Triassic extinction event that wiped out 95% of life on Earth serves as a model for studying the current biodiversity crisis. Researchers from the University of Bristol, the California Academy of Sciences, and the China University of Geosciences analyzed marine ecosystems before, during, and after the event to understand the series of events that led to ecological destabilization. They found that the rate of species loss today outpaces that during the Great Dying, and stress the importance of considering functional redundancy in modern conservation strategies.

Fungi are more than just pizza toppings or irritants like athlete's foot. They are a distinct life-form that plays a vital role in the health of our planet. Fungi can absorb oil spills, control insects' brains, and produce life-saving medicines like penicillin. They are also eco-warriors, essential to healthy soil and trapping CO2, potentially solving global warming on their own. Fungi are neither plant nor animal, but are genetically closer to animals than plants. They form dense fungal networks called mycelium, which plants use to communicate with each other. Fungi can also employ other organisms, like leaf-cutter ants, to do their work for them. Fungi are fascinating and adaptable, and there is still much we have yet to learn about them. By exploring the world of fungi, you can become a real fun-guy at parties and gain a deeper understanding of the world around you.
