A toxic protein forms dynamic pores in the membranes of brain cells—and that may be the key to understanding how Parkinson's disease develops. This is the conclusion of a new study from Aarhus University, where researchers ...

Astrocytes in the lateral hypothalamus region of the brain, an area involved in the regulation of sleep and wakefulness, play a key role in neuron activity in mice and affect their behavior, Canadian researchers have found.

Today, when an aging parent, relative, or friend starts to forget things, a firm diagnosis can be surprisingly elusive.

In the lab, it's easier to grow simple balls of cells than complex asymmetrical structures with two distinct ends—like the one million filtering units—nephrons—that make up a human kidney. But new research unveils a ...

Researchers from the University of Hong Kong have discovered that the Epstein-Barr virus (EBV), a common human virus closely linked to nasopharyngeal carcinoma (NPC), can change the 3D structure of the human genome inside ...

Nine of the 10 most common cancer deaths in Australia are caused by solid tumors, but in most cases it's the cancer's spread to other parts of the body—known as metastasis—that proves fatal.

The process of improving the synchronization between visual perception and motor skills is called visuomotor learning. It entails adaptation of movements based on visual information. This kind of training can help with skill ...

Hydrogels—materials like gelatin that can absorb and hold water—can aid wound healing and enable slow-release drug delivery, but they usually break down in acidic environments like the stomach.

Cells on the inner surface of the intestine are replaced every few days. But, how does this work? It was always assumed that cells leave the intestinal surface because excess cells are pushed out.

A newly discovered "timekeeper" for fighting infections dramatically shapes the body's immune defenses, offering insight as to why antiviral T cell response varies throughout the day, according to UT Southwestern Medical ...

We consider humans to be at the apex of social cognition. But we're not the only animals that closely interact with each other. Marmosets, for example, are highly social creatures. In the wild, they choose to work together, ...

Engineers at Duke University have developed a wireless patch that can noninvasively measure skin and tissue stiffness at depths of up to a couple of inches. Already smaller than a smartwatch, the device could be a gateway ...
