Sleeping in Flight: Adaptations of a Bird’s Brain

Flying has required birds to develop a plethora of tools to make it as efficient as possible. These biological tools range from different body sizes, body weights, wingspans, feather numbers and their distribution, to an increase in brain to body size ratio to accommodate more developed functions. Multiple types of…

Design, Purpose and Specificity of the Narwhal’s Tusk

The narwhal’s tusk is a fascinating organ as it has the composition of a tooth but very different properties, in particular its ability to grow in a straight line. To understand the design mechanism allowing this particular feature, we will first present the composition, function and properties of the tusk.…

How Computers and Robotics Helped Us Understand Flippers

The advancement of technology has allowed researchers to develop efficient software which aids in the recognition of animals based on their flippers, conduct experiments to further examine the parameters which define the efficacy of these limbs, and manufacture robots which simulate marine animals and their flippers to deepen the understanding…

Visual Lateralization in the Animal Kingdom

The vertebrate brain has succeeded in the specialization of different traits and abilities through dividing it into two hemispheres, where the left hemisphere is better than the right one when conducting certain tasks, and vice versa. This specialization, called brain lateralization, also effects vision in vertebrates. In fact, visual lateralization,…

Hypotheses for the Tooth Eruption Mechanism

Tooth eruption, the movement of the tooth germ from its non-functional position in the alveolar processes to its final function position in the oral cavity, is a little-known mechanism despite being highly documented. Many theories try to explain the mechanism of the eruption of the tooth; however, none succeed to…
