What is the science behind doppelgängers? In this fun episode of SciShow, two bespectacled science YouTubers enter, one bespectacled science YouTuber leaves ... because while they may look suspiciously alike, Joe Hanson has his own...

This week in news: Scientist successfully breed mice using same-sex parents and some very clever genetic engineering.

The media have been talking about “genetically modified humans” and “designer babies.” But what they’re really talking about is germ-line engineering: a process that could help eliminate heritable diseases. So why do some scientists want...

You thought you knew all the ways to make a baby.

Join the Amoeba Sisters as they explain gene and chromosome mutations, and explore the significance of these changes. This updated video has improved audio and images! Codons and the amino acids they code for is represented by standard...

Two bespectacled science YouTubers enter, one bespectacled science YouTuber leaves ... because while they may look suspiciously alike, Joe Hanson has his own channels while Hank’s gonna stick around here. The only question is who will...

Explore chromosomes and karyotypes with the Amoeba Sisters! This video explains chromosome structure, how chromosomes are counted, why chromosomes are important, and how they can be arranged in a karyotype! This video also tackles a few...

Uncover the miraculous journey of life cycles, observing how organisms like humans, butterflies, and plants grow, change, and reproduce.<b<br/>r/>

Biology Terms part 2

This video covers:<br/>
- What we mean by special<br/>ised cells
- How a sperm cell is ad<br/>apted for its funct<br/>ion
- What differentiation is
- Why differentiation is important

A video entitled “Cells in Your Body” which discusses the two main types of cells that make up the human body, focusing on how each type is formed.

Brit looks back on our fourth month on Nature League, when we explored the theme of sex and reproduction.

In this Nature League Field Trip, Brit goes on a Montana safari at the National Bison Range and shares some local stories of how species have persisted over time via reproduction.

The video discusses how different types of animal and plant cells are specialized for various functions. The video highlights sperm cells, nerve cells, muscle cells, root hair cells, sieve tubes, and flame cells to illustrate how each...

This video explains the concept of cell specialization and differentiation. The narrator discusses how cells differentiate to become specialized for their unique functions within an organism. The differences in differentiation between...

In this video, we will examine the precise site of fertilization and then follow the physical path of the secondary oocyte (egg) and sperm cell (spermatozoa) to fertilization.

This video dissects Jacob's syndrome, a benign genetic condition in which males have two Y-chromosomes (genotype XYY).<br/>

The video discusses cell specialization, explaining how cells are structured differently to suit their functions. Three types of specialized cells are examined, including sperm cells, egg cells, and ciliated epithelial cells. The video...

Did you ever wonder what happens to artificial sweeteners when you consume them in food? In this video, we track the fates of two of them (erythritol and sorbitol). They cause loose stool, but they can have other functions as well.

In this video, we explore the mechanisms that cause thoracic outlet syndrome by looking at the relevant anatomy and structures.

In this video, we explore the mechanism of the Robertsonian Translocation with acrosomal chromosomes and its correlation to Down Syndrome (Trisomy 21).

The video explains the various aspects of reproduction in biology, including sexual and asexual reproduction. It describes the differences between these two types of reproduction. The video also explains the process of meiosis and...

In this video, we explore more male reproductive anatomy [internal/external parts of the penis.<br/>

We just learned about class Anthozoa, which is the class of Cnidaria that contains all the corals. But there is much more to talk about with corals, as the massive coral reefs that they form act as entire ecosystems unto themselves....

This is the second video (part 2) in which we cover the anatomy of the female reproductive system. Specifically, we will cover, the specific regions of the uterus and Fallopian tubes, the layers of the uterus, and the various ligaments...
