As we continue to make strides in health and wellness, it's clear that innovation is happening on multiple fronts. On one hand, researchers are making progress in understanding and combating diseases, such as lung cancer, where a hidden immune weapon has been discovered. They're also gaining insight into how viruses work, which could lead to new treatments, and developing new tools, like a $10 chip that could bring medical lab capabilities to wearable devices.

Meanwhile, scientists are also exploring ways to promote overall health and wellness. However, a recent study found that fish oil supplements, often taken for brain health, may not have the benefits that were once thought. On a related note, researchers have also made advancements in understanding the inner workings of life, with a new microscope that could reveal the hidden machinery of life. And, as we go about our daily lives, it's worth being mindful of the foods and drinks we consume, like coffee, which has seen a significant increase in calorie content over time, with added ingredients beyond sugar contributing to the rise.
