R-spondin, which enhances the growth of healthy cells in the gut, suppresses the growth of intestinal adenoma cells, thus reducing the formation of intestinal tumors.

Carnegie Mellon Biomedical Engineering Department Head Bin He and his team have discovered that mindful meditation can help subjects learn and improve the ability to mind-control brain computer interfaces (BCIs).

Ever wonder why some fireflies flash in harmony? New research sheds light on this beautiful phenomenon and strives to understand how relatively simple insects manage to coordinate such feats of synchronization.

Carnegie Mellon University's Maysam Chamanzar and his team have invented an optical platform that will likely become the new standard in optical biointerfaces. He's labeled this new field of optical technology 'Parylene photonics,' demonstrated in a recent paper in Nature Microsystems and Nanoengineering.

Researchers at the National Institute of Standards and Technology (NIST) have developed a new method of 3D-printing gels and other soft materials. Published in a new paper, it has the potential to create complex structures with nanometer-scale precision.

A Northwestern University research team has developed a new theory that can predict the movement of an animal's sensory organs -- such as eyes, ears and nose -- while searching for something vital to its life.

Scientists have developed a new technique using tools made of luminescent DNA, lit up like fireflies, to visualize the mechanical forces of cells at the molecular level.

Researchers from the Structural Bioinformatics and Network Biology Laboratory at IRB Barcelona develop a system to predict tumour response to different treatments. Called Targeted Cancer Therapy for You (TCT4U), this system has allowed them to identify a set of complex biomarkers that are available to the medical-scientific community. The work has been published in the journal Genome Medicine.

Radio-resistance in bacteria first evolves through the adaptation of DNA repair mechanisms, however as evolution continues more mutations accumulate, and more cellular metabolic processes are affected. It is not yet clear which panel of mutations provides high-level resistance. The study shows that acquisition of radio-resistance via evolution is possible independent of other mechanisms like extreme dryness resistance (desiccation).
