A picture is worth a thousand words, the saying goes, meaning that a picture can tell a big story quickly, but what if it could also represent a hundred thousand other images? 

New software seeks to tame the vast amount of visual data in the world by generating a single photo that can represent massive clusters of images. This tool can give users the photographic gist of a kid on Santa's lap, housecats, or brides and grooms at their weddings. It works by generating an image that literally averages the key features of the other photos. 

Kidney failure is a devastating condition and there are never enough donors for recipients - so it seems strange that anyone would be hesitant about getting one, but a new paper in the Clinical Journal of the American Society of Nephrology suggest that interventions are needed to increase women's acceptance of living donor kidney transplantation.

An enzyme called 12-LO promotes obesity-induced oxidative stress in the pancreatic cells and that has been linked to diabetes (and pre-diabetes, if you prefer made-up conditions mainstream science wishes studies would stop claiming to be about).

12-LO's enzymatic action is the last step in the production of certain small molecules that harm the cell, according to a team from Indiana University School of Medicine. The findings will enable the development of drugs that can interfere with this enzyme, preventing or even reversing diabetes.  

The first analysis of space dust collected by a special collector onboard NASA's Stardust mission and sent back to Earth for study in 2006 suggests the tiny specks, which likely originated from beyond our solar system, are more complex in composition and structure than previously imagined.

The analysis, completed at a number of facilities including the U.S. Department of Energy's Lawrence Berkeley National Lab (Berkeley Lab) opens a door to studying the origins of the solar system and possibly the origin of life itself.

Trees have been a part of the human existence for as long as humans have existed but that doesn't mean we know everything about them, like why they are the size they are. What limits the height of trees? Is it the fraction of their photosynthetic energy they devote to productive new leaves? Or is it their ability to hoist water hundreds of feet into the air, supplying the green, solar-powered sugar factories in those leaves?

The easy and therefore not vary satisfying answer is that both resource allocation and hydraulic limitation might play a role, but the question still becomes which factor (or what combination) actually sets maximum tree height, and how their relative importance varies in different parts of the world.
