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.

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.

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.

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.
- Animals
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 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.

A taste map in the brain is a scattering of tiny flavor islands
Some senses are highly organized in the brain. Taste is not. And that points to just how important it is.

Scientists Say: Apoptosis
When it’s time for cells to die, they need to do it carefully, so they don’t harm other cells.

Scientists Say: Nucleus
Nucleus comes from the Latin term “nuc,” meaning nut or kernel. In science there are lots of nuclei. Every one of them is the center of something.
