Medical Xpress / Aging blocks the retina's ability to regrow lost neurons, a first-of-its-kind study finds

A new study from the laboratory of Levi Todd, Ph.D., at Upstate Medical University has found that aging significantly limits the ability of support cells in the retina, called glia, to be reprogrammed into new neurons, a ...

Phys.org / Virus-like particles enable gene activity tracking over time in the same cells

In recent years, scientists have developed methods to measure a cell's transcriptome, or all the RNA produced by a cell, to study the cell's identity and genetic activity. However, these methods rely on killing the cell to ...

Medical Xpress / Energy-hungry tissues expand cleanup crews to clear worn-out mitochondria

The body's heart muscle (for pumping blood), skeletal muscle (for movement and posture) and brown fat (for heat production) each require a lot of energy and make a lot of waste. That waste needs to be managed.

Phys.org / Archaea as 'flexitarians': Ammonia-oxidizing microbes also feed on amino acids

Symbiotic ammonia-oxidizing archaea in marine sponges are not strict specialists but true "flexitarians." A team led by microbiologists Bettina Glasl and Katharina Kitzinger from the University of Vienna, in collaboration ...

Phys.org / Turbulent times for star formation in Stephan's Quintet

Star formation in galaxies is closely linked to molecular gas. In the distant past, when galaxy interactions were more common, these encounters compressed molecular gas, causing dense clouds to collapse under their own gravity ...

Medical Xpress / Early mitochondrial stress reveals potential mechanism for lasting heart protection

Mitochondria are popularly known as the "powerhouse of the cell," but these cellular structures do much more—including acting as signaling hubs. Some signals that mitochondria send can reprogram the activity of the entire ...
