Targeted elimination of leukemic stem cells

Leukemia is caused by leukemic stem cells which are resistant to most known therapies. Relapses are also due to this resistance. Leukemic stem cells arise from normal blood-forming (hematopoietic) stem cells. Because they ...

Testing the fluorescent proteins that light up the brain

Neurons are cells in your brain. Shaped like little stars, they flicker and fire off signals to each other. The signals travel up and down the long tendrils, called dendrites, extending out from each point of a neuron's star-shaped ...

Real neurons are noisy. Can neural implants figure that out?

If human eyes came in a package, it would have to be labeled "Natural product. Some variation may occur." Because the million-plus retinal ganglion cells that send signals to the human brain for interpretation don't all perform ...

Using light instead of electricity in cochlear implants

A team of researchers affiliated with multiple institutions in Germany has developed a cochlear implant that converts sound waves to light signals instead of electrical signals. In their paper published in the journal Science ...

Researchers uncover a critical early step of the visual process

The key components of electrical connections between light receptors in the eye and the impact of these connections on the early steps of visual signal processing have been identified for the first time, according to research ...

Novel technique helps explain why bright light keeps us awake

In recent decades, scientists have learned a great deal about how different neurons connect and send signals to each other. But it's been difficult to trace the activity of individual nerve fibers known as axons, some of ...

Prosthetics for retinal stimulation

In a study recently published in Advanced Biomedical Engineering, researchers at Okayama University report a thin photoelectric film which can stimulate degenerated retinal tissues of the eye.
