New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick ...

Mint scent inhibits the growth of weeds

Some plants are very successful in the competition for space, nutrients, and water. They inhibit the growth of their competitors by chemical signals that cause cells of the neighboring plant to die. Scientists of the Botanical ...

Open sesame: Micro RNAs regulate plant pores

Environmental cues prompt small RNA segments to regulate the development and distribution of tiny pores involved in photosynthesis in plants. The finding by DGIST researchers in Korea was published in the Proceedings of the ...

A protein that pulls the brake on nerve growth

During embryonic development, nerve cells form long, thin extensions that wire up the complex network of the brain. Scientists from the German Center for Neurodegenerative Diseases (DZNE) in Bonn have now identified a protein ...

How cells protect themselves from mitochondrial defects

Cells need powerhouses known as mitochondria to utilize the energy stored in our food. Most of the proteins required for this powerhouse function are encoded in the nucleus and transported into the mitochondria after they ...

Why fruit flies eat practically anything

Say hello to the common fruit fly: a regular guest in most homes, feasting on that banana peel you tossed into the garbage a few days ago.

Study identifies a 'sensor' that activates cell migration

The cytoskeleton is a structure that not only helps cells maintain their shape and internal organisation, but also enables them to perform functions like movement and migration to sites far from the place where they originated. ...

Light-induced changes in photosensory proteins

Researchers from Charité - Universitätsmedizin Berlin have demonstrated on a molecular level how a specific protein allows light signals to be converted into cellular information. Their findings have broadened the understanding ...
