Hair and Nails Continue to Grow After Death
This article dispels the myth that hair and nails continue to grow after death by discussing the biological processes and presenting scientific evidence.
Cell Biology (Cytology)
Cell biology (cytology) is a branch of biology concerned with the study of the cell including it’s physical properties and how it relates to it’s environment.
The Square Cube Law Impacts Biomechanics
The square cube law says that volume increases faster than surface area when an object increases in size proportionally. This affects biomechanics (AKA the way organisms are built).
Nettie Stevens Discovered the XY Sex-determination System
Nettie Stevens and Edmund Beecher Wilson independently discovered the chromosomal XY sex-determination system (that males have XY and females have XX sex chromosomes).
All Mammals Start as Female
Mammals don’t start as females, they start as a blank slate with XX or XY genetic code, and for the first 5-6 weeks of gestation only the X gene expresses.
Some People are Born Gay
Science suggests people are born in a range of places in the gay and transgender spectrum, with both nature and nurture playing a role in sexuality.
Some Cells Can Live Forever
Some cells appear to be able to live forever in a lab. However the Hayflick limit sets a cap on the number of times a cell can divide.
Mirror Neurons Fire When Observing and Preforming an Action
Mirror neurons are neurons that “fire” when observing an action and when performing an action, this allows for learning through imitation (“mirroring”).
432 Hz is Better than 440 Hz
It’s theorized that using a starting pitch of A=432 Hz and a “just intonation” tuning method (scientific tuning) is more natural and mathematically symmetric than using A=440 Hz and “equal temperament” tuning (concert tuning).
There are Different Blood Types
There are four general blood types (A, B, AB, and O), each can be Rh ‘+’ or ‘-‘. Blood types differ by antigens on the surface of red blood cells.
Mushrooms are the Fruiting Bodies of Fungi
All mushrooms are fungi, but not all fungi are mushrooms. Mushrooms are the fruiting body of fungi that typically grow above ground.
