Scientists unravel mysteries of cells' whiplike extensions

Cilia, or flagella—whiplike appendages on cells—perform diverse tasks required to keep the body healthy. When cilia malfunction, the consequences can be devastating, causing a range of problems, from blindness, to lung ...

Dangerous bacteria communicate to avoid antibiotics

A bacterial infection is not just an unpleasant experience—it can also be a major health problem. Some bacteria develop resistance to otherwise effective treatment with antibiotics. Therefore, researchers are trying to ...

The filaments that structure DNA

They play a leading role not only in muscle cells: Actin filaments are one of the most abundant proteins in all mammalian cells. The filigree structures form an important part of the cytoskeleton and locomotor system. Cell ...

Magnesium deprivation stops pathogen growth

When pathogens invade cells, our body combats them using various methods. Researchers at the University of Basel's Biozentrum have now been able to show how a cellular pump keeps such invading pathogens in check. As the researchers ...

Cells lose their ability to share resources as we get older

A research team led by The University of Western Australia has found that our cells deteriorate and share fewer resources as we age, which can lead to the onset of diseases such as osteoporosis, arthritis, cardiovascular ...

The antibiotic arms race moves at high speed

Acinetobacter baumannii is a pathogen that creates serious problems in hospitals throughout the world. It causes opportunistic infections in the bloodstream, urinary tract, and other soft tissues, accounting for as much as ...
