Biology made simpler with clear tissues

Thanks to techniques developed at Caltech, scientists can see through tissues, organs, and even an entire body. The techniques offer new insight into the cell-by-cell makeup of organisms - and the promise of novel diagnostic medical applications.

Implanted neurons become part of the brain

Scientists have grafted neurons reprogrammed from skin cells into the brains of mice for the first time with long-term stability. Six months after implantation, the neurons had become fully functionally integrated into the brain.

How sweet it is: New tool for characterizing plant sugar transporters

A powerful new tool that can help advance the genetic engineering of 'fuel' crops for clean, green and renewable bioenergy, has been developed by researchers with the U.S. Department of Energy (DOE)?s Joint BioEnergy Institute (JBEI). The JBEI researchers have developed an assay that enables scientists to identify and characterize the function of nucleotide sugar transporters, critical components in the biosynthesis of plant cell walls.

Stem cells from nerves form teeth

Scientists have discovered that stem cells inside the soft tissues of the tooth come from an unexpected source, namely nerves. These findings contribute to brand new knowledge of how teeth are formed, how they grow and how they are able to self-repair.

Junk DNA not as worthless as once thought

Around 75 per cent of the supposed functionless DNA in the human genome is transcribed into so-called non-coding RNAs (ribonucleic acid). To date, little is known about its function. Researchers have now been able to demonstrate that the production of non-coding RNAs is precisely regulated. They suspect that non-coding RNAs might play a role in regulating cellular processes or in the modified immune response following exposure to environmental toxicants.
