Dog ear movement

Scientists are still learning about the genes that control dog ear movements and the biochemical pathways that produce this ability. However, they have made significant progress in recent years.

In 2015, researchers published a study in the journal BMC Genomics that identified a cluster of SNPs on chromosome 10 that are associated with ear type in dogs. These SNPs are located near two genes: methionine sulfoxide reductase (MSRB3) and high-mobility group AT-hook 2 (HMGA2). MSRB3 is involved in human hearing, and HMGA2 is involved in human height.

The researchers believe that these SNPs may play a role in regulating the development of the ear muscles and cartilage. They also found that the region containing these SNPs has been under selection during dog domestication, suggesting that humans may have played a role in shaping the evolution of dog ear type.

Another study, published in the journal PLOS Genetics in 2020, identified a specific gene, called ALX4, that is involved in ear development in dogs. Researchers found that dogs with a mutation in the ALX4 gene have floppy ears. This suggests that ALX4 plays a role in regulating the development of the ear muscles and cartilage in dogs.

Scientists are still working to understand the exact role that these genes play in dog ear movement and how they interact with each other. However, the research so far suggests that dog ear movement is controlled by a complex network of genes.

At the biochemical level, the pathways that produce dog ear movement are likely to involve a variety of proteins and signaling molecules. For example, the ALX4 gene is known to encode a protein that plays a role in the development of muscle and cartilage. It is likely that this protein interacts with other proteins and signaling molecules to regulate the development and function of the ear muscles and cartilage in dogs.

Overall, scientists are making significant progress in understanding the genes and biochemical pathways that control dog ear movement. However, there is still much more to learn.

Challenges to understanding dog ear movement

There are a number of challenges to understanding dog ear movement. One challenge is that dog ear movement is a complex behavior that is likely to be controlled by a network of genes. Another challenge is that it is difficult to study ear movement in dogs in a controlled setting.

Finally, it is important to note that dog ear movement is not just a physical behavior. It is also a form of communication. Dogs use their ears to express a variety of emotions, such as alertness, fear, and aggression. This makes it difficult to separate the physical aspects of ear movement from the communicative aspects.

Despite these challenges, scientists are making progress in understanding dog ear movement. This research has the potential to lead to new insights into the evolution of dog domestication and the development of new treatments for ear problems in dogs.

America’s Bee Problem Is an Us Problem - The Ringer

The problem of bees in America is not a question of peace with the environment. It's not really even a matter of conservation, per se. The bees most folks believe ought to be saved are neither natural to the land nor essential to it. They are, instead, integral to our agricultural system, grocery stores, refrigerators, and pantries. We have built a machine in the span of centuries, and it fits so comfortably together. How and why this happened is a story as much about the appeal, adaptability, and shortcomings of American commerce as it is about the dying of bees.

Daniel Ellsberg Is Dying. And He Has Some Final Things to Say. - POLITICO

The need for whistleblowing in my area of so-called national security is that we have a secret foreign policy, which has been very successfully kept secret and essentially mythical," he says. "I'm saying there's never been more need for whistleblowers … There's always been a need for many more than we have. At the same time, it's become more and more dangerous to be a whistleblower. There's little doubt about that.
