Casein Protein vs. Whey Protein: Which One Is Right for You? When it comes to protein supplements, casein and whey protein often take center stage. Both are derived from milk and are popular among fitness enthusiasts, athletes, and anyone looking to boost their protein intake. However, they differ in how they work, their digestion speed, and their benefits. Understanding these differences can help you decide which one suits your goals better. In this article, we’ll dive deep into casein protein and whey protein to explore their unique characteristics, benefits, and ideal uses. Casein Protein vs. Whey Protein What Are Casein and Whey Protein? Casein Protein Casein is the primary protein found in milk, accounting for about 80% of its total protein content. It is slow-digesting and releases amino acids steadily over several hours. This slow-release nature makes casein an excellent choice for prolonged periods without food, such as overnight or between meals. Casein forms a gel...
A new study in the journal Cell reveals something surprising: ancient viruses may have helped shape our bodies and brains. These viruses, which infected vertebrates millions of years ago, played a crucial role in the evolution of our nervous systems and large sizes.
Researchers focused on a substance called myelin, which coats nerve fibers and helps messages travel quickly in our bodies. They found that a gene sequence from these old viruses is essential for making myelin. This gene is now found in many animals, from mammals to fish.
Dr. Tanay Ghosh, who led the study, searched through DNA databases to find clues about how myelin evolved. He discovered a specific sequence called "RetroMyelin" that comes from these ancient viruses. When they experimented with cells, they found that knocking out this sequence stopped them from making myelin.
What's really interesting is that this RetroMyelin sequence isn't just in mammals like us – it's in all sorts of animals with backbones, from birds to fish. It seems to have appeared around the same time as jaws evolved, about 360 million years ago.
Having myelin was a big advantage for animals. It helped them react faster to danger, whether they were hunting or trying to escape. It also allowed their nerves to grow longer, which meant they could have bigger bodies.
The study suggests that these ancient viruses infected vertebrates multiple times, leading to the wide variety of animals we see today. So, these viruses weren't just making us sick – they were also shaping our evolution.
Dr. Robin Franklin, another scientist involved in the study, says that viruses aren't always bad. Sometimes they can actually help drive important changes in our bodies over time.
This discovery opens up new avenues for understanding how our bodies have evolved and how viruses have influenced our biology throughout history. It's a reminder that even the smallest things, like ancient viruses, can have a big impact on the way life on Earth has developed.
