Light impulses can be used to trigger electrical excitation in plants

Optogenetics denotes the manipulation of cellular processes by light-based biological techniques. An international research team led by the Würzburg plant scientists Rainer Hedrich, Georg Nagel and Dirk Becker has succeeded in applying this method to higher plants: Light impulses can now be used to trigger electrical excitation in plants.

Compound in pickled capers can activate proteins required for bodily processes

A compound commonly found in pickled capers has been shown to activate proteins required for normal human brain and heart activity, and may even lead to future therapies for the treatment of epilepsy and abnormal heart rhythms.

Researchers identify a new role for covalent linker involved in biological ion channel

Ion channels are essentially passageways through membranes that transport signals to a cell’s environment and enable it to respond.

Single-nucleus RNA sequencing helps compare transcriptional responses to acute cocaine

The lab of Jeremy Day, Ph.D., at the University of Alabama at Birmingham, has used single-nucleus RNA sequencing approaches to compare transcriptional responses to acute cocaine in 16 unique cell populations from a portion of the brain called the nucleus accumbens, or NAc.

Scientists discover role of surface diffusion in protein transport

Many of the most promising medicines under development are proteins, often antibodies, to help patients fight disease. These proteins must be purified as part of the manufacturing process -- a task that can be tricky and result in costly waste.

DNA repair tool is tailored to deal with specific type of complex break, study shows

Our cells are constantly dividing, and as they do, the DNA molecule - our genetic code - sometimes gets broken. DNA has twin strands, and a break in both is considered especially dangerous.

Researchers track how key brain receptor works

For the first time, researchers in the lab of CSHL Professor Hiro Furukawa have been able to track each atom in the NMDA receptor, an important brain protein, as it transmits or inhibits neural signals.

Princeton researcher solves long-standing mysteries of membrane protein structure

Ion channels and membrane transporters are in the business of moving ions and small molecules across cellular membranes. They are essential for metabolic and cellular homeostasis, and for a host of biological signaling pathways.

Researchers identify osmotic stress as stimulator of cellular waste disposal

Cellular waste disposal, where autophagy and lysosomes interact, performs elementary functions, such as degrading damaged protein molecules, which impair cellular function, and reintroducing the resulting building blocks such as amino acids into the metabolic system.
