Conduct an investigation to provide evidence that living things are made of cells, either one cell or many different numbers and types of cells.
- Microbes
Scientists Say: Bacteria
Bacteria get a bad rap for making people sick, but only a tiny portion of these single-celled creatures cause disease.
- Life
In blazing heat, some plants open leaf pores — and risk death
When heat waves and droughts collide, water is precious. Some thirsty plants try to cool off by opening tiny pores — only to lose water even faster.
- Microbes
Genes point to how some bacteria can gobble up electricity
A new study shows how some microbes absorb and release electrons — a trait that may point to new fuels or ways to store energy.

Analyze This: Hardened wood can make sharp steak knives
Researchers treated wood to make it hard and dense. Out of it, they carved sharp knives and nails that could substitute for ones made of steel.
- Microbes
Let’s learn about microbes
There may be a billion species of microorganisms on Earth — but scientists have only discovered a small fraction of them.
- Tech
No animal died to make this steak
The ribeye steak is the first of its kind, and the latest in a growing list of meats printed with a 3-D bioprinter instead of being harvested from an animal.
- Brain
Explainer: What is a neuron?
From the moment you are born, cells called neurons sense information, process it and then pass it on. Neurons allow you to do everything that you do.

Search for ‘rewards’ is big driver in remodeling a teen’s brain
Communication ‘highways’ in the brain undergo a major overhaul as children morph into adults. Dopamine plays a big role in this remodeling project.
- Brain
Scientists Say: Neuron
Neurons are the foundational cells in the nervous system. They pass along and process information using electrical signals.
- 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.
- Animals
Scientists Say: Organelle
An organelle is a part of a cell with a particular function. Like organs. But for cells.
- 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.
