Living things use sound for communication, navigation, and even hunting. This requires ‘auditory perception’ – how our brain interprets the sounds in our environment. For many species, the ear is key to hearing –  scientists think that the middle ear in humans evolved from the gills of fish – is that true for all species? For example, do bees have ears, and more importantly, do they need them? How bees communicate Bees in a bee hive on honeycombs.

Polynomials are algebraic expressions with fixed numbers called constants and terms that can change called variables, connected through operators like addition, multiplication, etc., and the power on the variables are always non-negative integers. Polynomials are almost used in every field that needs math. This blog will explain the basics of polynomials and some terms related to polynomials. Structure of a polynomial Let’s take the example of 2x4 + 3x2 + 7x + 4 4 is a fixed number, hence constant. The value of x can be any number; hence, the value is not constant. We call it a variable ..read more

If you are a mother planning a residential move and wondering how moving affects kids, you’re not alone. Data from the U.S. Census Bureau shows that 17% of families with children, both preschool and school-aged, experience at least one residential move each year (U.S. Census Bureau, 2007). Moving as an adult can send ripples through the fabric of your existence, influencing behavioral patterns, social activities, and even your self-esteem. This is especially true because moving is linked with illness, loss of employment, and divorce. These changes impact kids, especially when they are young ..read more

Birds peck and don’t chew; there you go, we have the answer to the question. No, they don’t have teeth, as beaks are for pecking and teeth for chewing. Birds’ extinct ancestors carried teeth, so why don’t they have teeth? Birds branched over 100 million years ago from dinosaurs. We don’t need to watch Jurassic Park to remember their ferocious teeth. Then, what could be the evolutionary advantage for birds to go toothless? Skipped teeth for a better lifestyle Adaptation is about blending into one’s food and habitat, which, in birds, are nuts and flying. When consuming seeds and nuts, a beak ..read more

There is a misconception that you must possess flappy ears for auditory perception. Is it possible to hear without ears? Today, let’s see how turtles hear when they have no ears. We wonder how these animals hear without those external ears fluttering, as seen in dogs or elephants. Technically, turtles do not have ears but are not deaf – they have internal ears. Understanding hearing The outer ear channels external sounds to the middle ear, where the eardrum and auditory bones amplify the sound waves. The inner ear is the last stop for the sound waves, where they are converted to electrical ..read more

Robotaxi might be the first autonomous car to be marketed extensively. Credits: Wikimedia/Grendelkhan Elon Musk dropped a tweet in the first week of April saying that Tesla will unveil its robotaxi on 8th August. Tesla cars already have full self-driving (FSD) mode and autopilot features to assist drivers. However, these features still need supervision. With FSD hitting the benchmark of a billion miles driven on it, a new era is seemingly on the way for Tesla owners. Musk has already displayed his affinity towards self-driving cars. He has reportedly asked his team to focus on an autonomous ..read more

Electric cars or electric vehicles (EVs) may look like conventional cars but are completely different. They are less noisy and more responsive while also generating lower vehicle emissions and no exhaust emissions compared to traditional vehicles. They also look completely different under the hood, meaning they do not have many of the components we are used to having in older cars! But do electric cars have gears? Single-speed transmission Close-up of the gear in car transmission. Credits: DepositPhotos/chungking Electric cars typically lack the multi-speed transmissions found in conventio ..read more
