Control of a mitochondrial protective mechanism identified

Mitochondria are essential for normal functioning of almost all cells, since they are the main production sites of the energy-carrying molecule adenosine triphosphate (ATP). In addition, mitochondria are the key sites of ...

Chemical 'vaccine' helps plants repel pathogens

When plants come under attack from invading bacteria, viruses or fungi, they mount a two-pronged response, producing both offensive chemicals to kill invaders and defensive chemicals to prevent infestations from spreading.

Surface protein editing in bacteria

University of Minnesota researchers have discovered this previously unknown signaling pathway that regulates surface proteins on bacteria that can lead to new targets for antibiotics.

Infertility's roots in DNA packaging

Pathological infertility is a condition affecting roughly 7 percent of human males, and among those afflicted, 10 to 15 percent are thought to have a genetic cause. However, pinpointing the precise genes responsible for the ...

New possible target for treating major common diseases

There is a large, untapped potential for developing drugs against cancer, fibrosis and cardiovascular diseases by targeting a family of receptors known as Frizzleds, researchers at Karolinska Institutet in Sweden believe. ...

How infectious bacteria hibernate through treatment

Disease-causing bacteria can develop resistance to antibiotics which are then no longer effective in treating infection, yet they also have another tactic to avoid being killed off by antibiotic treatment. Some cells of the ...

Synchrotron science could give soybeans a boost

Scientists at the University of Liverpool, together with Japanese colleagues, have gained new insight into how soil bacteria sense and adapt to the levels of oxygen in their environment. The findings could be used to help ...
