One of the most exciting advancements in stem cell research has been the development of organoid systems, which are organ-like three-dimensional structures that mimic their corresponding organ in vivo. In this important review in Digestive and Liver Disease, published by Elsevier, scientists highlight some of the established and exciting novel uses for organoids or "organs in a dish" in gastroenterology and hepatology and look towards the future in this exciting field.

Diabetes drug alleviates anxiety in mice
The antidiabetic medication metformin reduces anxiety-like behaviors in male mice by increasing serotonin availability in the brain, according to a study published in JNeurosci. These findings could have implications for the treatment of patients with both metabolic and mental disorders.

New algorithm may help people store more pictures, share videos faster
The world produces about 2.5 quintillion bytes of data every day. Storing and transferring all of this enormous—and constantly growing—number of images, videos, Tweets, and other forms of data is becoming a significant challenge, one that threatens to undermine the growth of the internet and thwart the introduction of new technologies, such as the Internet of Things.

New organic flow battery brings decomposing molecules back to life
After years of making progress on an organic aqueous flow battery, Harvard University researchers ran into a problem: the organic anthraquinone molecules that powered their ground-breaking battery were slowly decomposing over time, reducing the long-term usefulness of the battery.

A prosthetic foot that tackles tough terrain
Taking on a hiking trail or a cobblestone street with a prosthetic leg is a risky proposition—it's possible, but even in relatively easy terrain, people who use prostheses to walk are more likely to fall than others. Now, Stanford University mechanical engineers have developed a more stable prosthetic leg—and a better way of designing them—that could make challenging terrain more manageable for people who have lost a lower leg.

Trap-and-release accelerates study of swimming ciliated cells
Researchers at Washington University in St. Louis have been studying cilia for years to determine how their dysfunction leads to infertility and other conditions associated with cilia-related diseases. Now, they will be able to perform these studies more rapidly through a new method that uses sound waves to momentarily trap cells propelled by cilia, then releases them to measure their movement as they swim away.

Six fingers per hand
Polydactyly is the extraordinary condition of someone being born with more than five fingers or toes. In a case study published in Nature Communications, researchers from the University of Freiburg, Imperial College London, the University Hospital of Lausanne, and EPFL have for the first time examined the motor skills and sensorimotor brain areas in people with polydactyly. The results show that an extra finger can significantly extend the manipulation abilities and skill. It enables people with six fingers to perform movements with one hand where people with only five fingers would need two hands. The augmented motor abilities observed in the polydactyly subjects are made possible by dedicated areas in the sensorimotor brain areas. These findings may serve as blueprint for the development of additional artificial limbs extending motor abilities.
