How does the immune system work?
Inside you, a daily battle is being waged and your immune system is at the frontline. Most of the time, you may not even notice it's there, but over the course of your life your immune system will guard you against hundreds of potentially fatal threats. Emma Bryce explores the different components of this system and how, together, they do their vital work.
You are your microbes
From the microbes in our stomachs to the ones on our teeth, we are homes to millions of unique and diverse communities which help our bodies function. Jessica Green and Karen Guillemin emphasize the importance of understanding the many organisms that make up each and every organism.
What causes antibiotic resistance
Right now, you are inhabited by trillions of microorganisms. Many of these bacteria are harmless (or even helpful!), but there are a few strains of ‘super bacteria’ that are pretty nasty -- and they’re growing resistant to our antibiotics. Why is this happening? Kevin Wu details the evolution of this problem that presents a big challenge for the future of medicine.
How do germs spread (and why do they make us sick)?
Germs are found on almost every surface we come in contact with, which makes it incredibly common for our bodies to be exposed to them. But why are some of these germs relatively harmless, while others can be fatal? Yannay Khaikan and Nicole Mideo explore this question by examining germs’ varying modes of transmission.
The beneficial bacteria that make delicious food
Where does bread get its fluffiness? Swiss cheese its holes? And what makes vinegar so sour? These foods may taste completely different, but all of these phenomena come from microorganisms chowing down on sugar and belching up some culinary byproducts. Erez Garty shows how your kitchen functions as a sort of biotechnology lab, manned by microorganisms that culture your cuisine.
How the food you eat affects your gut
The bacteria in our guts can break down food the body can’t digest, produce important nutrients, regulate the immune system, and protect against harmful germs. And while we can’t control all the factors that go into maintaining a healthy gut microbiome, we can manipulate the balance of our microbes by paying attention to what we eat. Shilpa Ravella shares the best foods for a healthy gut.
