How nerve cells control misfolded proteins

Researchers have identified a protein complex that marks misfolded proteins, stops them from interacting with other proteins in the cell, and directs them toward disposal. In collaboration with the neurology department at ...

Technique uses well-known dye to watch amyloid plaques in the brain

While amyloid plaques have long been closely associated with mechanisms driving Alzheimer's disease, visualizing how amyloid proteins assemble continues to prove difficult. The nanometer-sized amyloid fibrils are only a fraction ...

Scientist constructs artificial photosynthetic cells

A team led by associate professor Yutetsu Kuruma of the Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology has constructed simple artificial cells that can produce chemical energy that helps synthesize parts ...

Toxin-spewing bacteria decoded

Scientists at Emory University School of Medicine have identified a central regulator of toxin production in the bacterium C. difficile, the most common cause of healthcare-associated infections in the United States. C. difficile ...

New tool allows scientists to catch elusive protein in action

Like many of the processes that drive a cell's basic functions, those enabling the splitting of a newly-replicated cell into two, shown above, happen quickly. So quickly, in fact, that scientists often have a hard time pinpointing ...

The sticky science of underwater adhesives

Mussels stick to rocks on the seafloor, to aquatic plants, and—to the consternation of boaters—they can hitch rides fastened to seafaring vessels no matter their composition: metals, rubber, glass, wood and more.

Turning silenced cancer genes back into fighters

Working with human colon cancer cells and mice, researchers led by experts at the Johns Hopkins Kimmel Cancer Center say they have successfully blocked the activity of portions of a protein known as UHRF1 and restored the ...
