Heredity: Inheritance and Variation of Traits
- Genetics
Let’s learn about DNA
DNA is made of two chemical chains twisted around each other. It stores information that allows cells to grow and function.

Bringing COVID-19 vaccines to much of world is hard
The price of not vaccinating nearly everyone across the world could be a longer pandemic and more troubling variants of the new coronavirus.
- Life
Scientists Say: Egg and sperm
An egg or a sperm cell contains half of the normal genes an organism needs. They fuse together to form a new individual.
- Humans
By not including everyone, genome science has blind spots
Little diversity in genetic databases makes precision medicine hard for many. One historian proposes a solution, but some scientists doubt it’ll work.

Some young adults will volunteer to get COVID-19 for science
Researchers will soon give some healthy people the new coronavirus. Their young volunteers have agreed to get sick to speed coronavirus research.
- Animals
How do you build a centaur?
A centaur has the torso of a human and the body of a horse. It may sound cool, but it wouldn’t work very well.
- Space
Space travel may harm health by damaging cells’ powerhouses
Biochemical changes after going to space suggest that harm to cells’ energy-producing structures, called mitochondria, could explain astronauts’ health issues.
- Humans
Some identical twins don’t have the exact same DNA
Identical twins may not be exactly identical. Mutations may arise early in development that account for tiny genetic differences between siblings.

Early details emerge about the new U.K. coronavirus variant
The variant may spread more easily from person to person. That could make continuing to wear masks all the more important, experts say.
- Health & Medicine
When physicians and veterinarians team up, all species benefit
When doctors for people and those for animals share their expertise, they can discover new ways to take better medical care of all species.
- Plants
Here’s how giant pumpkins get so big
Cinderella took a ride in a pumpkin coach. Though real pumpkins do get big enough, here’s why their ride would be uncomfortable at best.

Gene editing can alter body fat and may fight diabetes
Researchers have long dreamed of using brown fat to fight obesity and diabetes. Work in animals shows they’re closing in on achieving that dream.
