MIT physicists have observed a resonance in colliding ultracold molecules for the first time, shedding light on the mysterious forces that drive molecules to chemically react. The team found that a cloud of super-cooled sodium-lithium (NaLi) molecules disappeared 100 times faster than normal when exposed to a very specific magnetic field, indicating that the magnetic field tuned the particles into a resonance, driving them to react more quickly than they normally would. These findings suggest that scientists could one day harness particles’ natural resonances to steer and control certain chemical reactions.

Self-heating convenience food has been around for decades, but have you ever wondered how it works? This exciting field of food science combines chemistry, physics, and engineering to create meals that heat themselves. Let's take a closer look at the science behind these on-the-go meals. First, let's explore the technology behind self-heating food. The packaging for self-heating meals is made up of several layers, including a water pouch, a heating element, and an insulating layer. When the pouch is squeezed, it releases water, which then comes into contact with the heating element, creating a chemical reaction that generates heat. This chemical reaction is based on the principle of exothermic reactions, which release energy in the form of heat. The heating element in self-heating food typically contains a mixture of calcium oxide and water, which react to create calcium hydroxide and heat. This reaction is often catalyzed by a small amount of sodium chloride. But how does this chemical reaction actually heat up the food? The heat generated by the reaction is transferred to the surrounding water, which then heats up the food in the container. The insulating layer of the packaging helps to keep the heat trapped inside the container, ensuring that the food stays hot for several minutes. Innovation in self-heating food technology has come a long way since the first self-heating meals were introduced in the 1960s. Today, companies like Hot-Can and OMEALS have developed sophisticated self-heating meal kits that include a variety of menu options, from pasta dishes to breakfast sandwiches. Leading academics in the field of self-heating food technology include Dr. Gregory Ziegler, a professor of food science at Penn State University, who has studied the properties of different materials used in self-heating packaging. With so many fascinating aspects to explore, the science of self-heating convenience food is an excellent topic for students looking to independently explore academic topics through reading, reflection, writing, and self-directed projects.

The periodic table may seem like just another table of information, but it is so much more. It is a tool that scientists use to understand the world around us.

Glass is a material that we use every day, but have you ever wondered how it works? Glass is made from silicon dioxide, which is heated until it becomes a flowing liquid. As it cools, the molecules lose energy and become an amorphous solid, allowing light to pass through without being scattered. The subatomic level of glass is what makes it transparent, as the electrons in glass are spaced far enough apart that visible light can't provide enough energy for them to jump between them. This unique property has made glass an essential material for many uses, from windows to lenses. Understanding the science behind glass can help you appreciate the importance of this material in modern civilization.

Teflon, a material that doesn't stick to anything, was stumbled upon accidentally in 1938 by a chemist named Roy Plunkett. Teflon's properties make it perfect for things that need to be slippery, chemical-resistant, or waterproof, which means it has a lot of applications. It can be found all over the place, from raincoats to industrial ball bearings to artificial joints. The incredible properties of PTFE, the chemical name for Teflon, come from its molecular structure. It's a polymer, meaning it's made of long chains of repeating units of atoms strung together. PTFE has tight carbon-fluorine bonds that ignore the normal, intermolecular forces that help substances stick to each other. Even the famously adhesive feet of geckos usually can't get a grip on it. Learning about the properties of materials like Teflon can inspire independent exploration of science and engineering, which can lead to exciting career opportunities in fields like materials science and chemical engineering.

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.
