New understanding of the inner world of lysosomes

Researchers at Duke-NUS Medical School and colleagues in Singapore have identified a protein that transports degraded membrane lipids out of lysosomes, cellular organelles that are the breakdown factories of cells. The findings, ...

Light-powered microbes are super-producing chemical factories

Sharing is key to living in society, whether it's toddlers sharing toys or nations sharing natural resources; but there's no avoiding the fact that one side getting more means that the other side gets less. Now, researchers ...

SRC-3 is a key regulator of the 12-hour clock

Many people have heard of the circadian rhythms or biological processes that follow a 24-hour cycle. Sleeping at night and being awake during the day is a well-known example of a circadian rhythm. Less well known are the ...

How bacteria cope with stress

When exposed to stress, bacteria allow their metabolism to take a break during which they suppress, for example, the incorporation of proteins into membranes. Scientists from Marburg, Freiburg and Munich have discovered this ...

Biologists shed light on how cells move resources

Florida State University researchers have new insight into the tiny packages that cells use to move molecules, a structure that is key to cellular metabolism, drug delivery and more.

Cellular stress causes cancer cell chemoresistance

There is a broad range of mechanisms associated with chemoresistance, many of which to date are only poorly understood. The so-called cellular stress response—a set of genetic programs that enable the cells to survive under ...

Why do birds typically live longer than mammals?

Why do birds typically live longer than mammals? A new paper offers a hint, albeit not a conclusive answer. Assistant Professors of Biology Cynthia Downs and Ana Jimenez at Hamilton College and Colgate University respectively ...
