Joanne Chory, director of the Plant Molecular and Cellular Biology laboratory at the Salk Institute for Biological Sciences and a Breakthrough Prize recipient, has created an initiative called “Harnessing Plants for the Future” to develop a super plant that will both provide food and store carbon dioxide in its roots. A “super chickpea plant” now in development could remove huge amounts of excess atmospheric carbon dioxide and fix it in the soil, greatly diminishing the impacts of climate change (not to mention producing large amounts of tasty hummus). But fear of anti-GMO activists has so far deterred her from using the Crispr gene-editing tool to speed work on the plant.

Associated Press developer-journalist extraordinaire Jonathan Stray gives a brilliant explanation of the use of data-mining strategies to winnow and wring journalistic sense out of massive numbers of documents, using the Iraq and Afghanistan war logs released by Wikileaks as a case in point. The concepts for focusing on certain groups of documents and ignoring others are hardly new; they underlie the algorithms used by the major Web search engines. Their use in a journalistic context is on a cutting edge, though, and it raises a fascinating quandary: By choosing the parameters under which documents will be considered similar enough to pay attention to, journalist-programmers actually choose the frame in which a story will be told. This type of data mining holds great potential for investigative revelation — and great potential for journalistic abuse.

In a series of recent findings, researchers describe bacteria that communicate in sophisticated ways, take concerted action, influence human physiology, alter human thinking, bioengineer the environment and control their own evolution. They may even think. The abilities of bacteria are interesting to understand in their own right, and knowing how bacteria function in the biosphere may lead to new sources of energy or ways to degrade toxic chemicals, for example. But emerging evidence on the role of bacteria in human physiology brings the wonder and promise — and the hazards of misunderstanding them — up close and personal.
Because in a very real sense, bacteria are us. Recent research has shown that gut microbes control or influence nutrient supply to the human host, the development of mature intestinal cells and blood vessels, the stimulation and maturation of the immune system, and blood levels of lipids such as cholesterol. They are, therefore, intimately involved in the bodily functions that tend to be out of kilter in modern society: metabolism, cardiovascular processes and defense against disease. Many researchers are coming to view such diseases as manifestations of imbalance in the ecology of the microbes inhabiting the human body. If further evidence bears this out, medicine is about to undergo a profound paradigm shift, and medical treatment could regularly involve kindness to microbes.
