Research identifies earlier origin of neural crest cells

Neural crest cells—embryonic cells in vertebrates that travel throughout the body and generate many cell types—have been thought to originate in the ectoderm, the outermost of the three germ layers formed in the earliest ...

Machine learning tracks moving cells

Both developing babies and elderly adults share a common characteristic: the many cells making up their bodies are always on the move. As we humans commute to work, cells migrate through the body to get their jobs done. Biologists ...

Study answers longstanding cell-development riddle

During the lifetime of a body—whether human, fish or any other type of vertebrate—cells die, making room for fresh new cells to carry on vital processes. The dead cells must be cleared away, though, and debris removal ...

Inhibitory neurons have two types of impact on brain oscillations

Studying the brain involves measuring the activity of billions of individual brain cells called neurons. Consequently, many brain measurement techniques produce data that is averaged to reflect the activity of large populations ...

Climate crisis: We are the system that needs to change

Climate change no longer seems just a future threat. In 2019, major fires in Australia, Russia and California burned over 13.5 million hectares of land—an area four times greater than the size of Belgium. Major floods and ...

How stem cells choose their careers

"What do you want to be when you grow up?" is a question it seems like every child gets asked. A few precocious ones might answer "a doctor" or "an astronaut," but most will probably smile and shrug their shoulders. But well ...

Becoming a nerve cell: Timing is of the essence

Mitochondria are small organelles that provide the energy critical for each cell in our body, in particular, in the energy-demanding brain. In this week's edition of Science, a Belgian team of researchers led by Pierre Vanderhaeghen ...

Induced neural stem cells: Not quite ready for prime time

(PhysOrg.com) -- The great promise of induced pluripotent stem cells is that the all-purpose cells seem capable of performing all the same tricks as embryonic stem cells, but without the controversy.

Drug-proof zebrafish reveal secrets of addiction

The effects of amphetamines on gene expression in zebrafish have been uncovered. This new study, published in BioMed Central's open access journal Genome Biology, provides clues to the genetics that underlie susceptibility ...
