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

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.

A glowing new way to measure antibodies
Researchers invent a way to detect and measure antibodies with glowing proteins. Antibodies can mark exposure to various diseases.
- Life
If bacteria stick together, they can survive for years in space
Tiny clumps of bacteria can survive at least three years in outer space. This raises the prospect of interplanetary travel by microbial life.

Can we taste fat? The brain thinks so
Scientists had not considered fat a 'taste.' The brain begs to differ, new data show.
