Engineering-minded scientists have taken notice that many types of fish have bodies shaped like a low-drag airfoil that are characteristic of airplane wings. Now, a new research study has proven that the engineered mechanics of this design in fish provide optimized movement and thrust for swimming.¹

One hundred percent effective. How often does that happen, especially in the dog-eat-dog world of biology? Researchers from the University of Bristol in the UK and Graz University in Austria found exactly that in a life-saving strategy that a species of flying cricket uses. Where does perfection like this come from?

Spinosaurus aegyptiacus had a longer body than the enormous T. rex. In Nature journal, researchers published a new reconstruction of the extinct reptile’s tail, showing that it would have undulated side-to-side.¹ They found that the tall, flattened tail was well-suited to swimming.

A new study published in the journal PLOS ONE has found that T. rex had legs made more for walking, rather than running.¹ Their long legs were well designed for sustained foraging.

T. Alexander Dececchi (from the Department of Biology, Mount Marty College in Yankton, South Dakota) and colleagues from several institutions began their article by stating,

Pig populations are having their ups and downs.

For domestic swine raised as livestock, the problem is a decreasing population. Some herds have succumbed to the swine flu,¹ and some pork processing plants are required to shut down.
