A new imaging tool developed by Boston scientists could do for the brain what the telescope did for space exploration. In the first demonstration of how the technology works, published July 30 in the journal Cell, the researchers look inside the brain of an adult mouse at a scale previously unachievable, generating images at a nanoscale resolution. The inventors’ long-term goal is to make the resource available to the scientific...

Rice University scientists are forging toward tunable carbon-capture materials with a new study that shows how chemical changes affect the abilities of enhanced buckyballs to confine greenhouse gases. The lab of Rice chemist Andrew Barron found last year that carbon-60 molecules (aka buckyballs, discovered at Rice in the 1980s) gain the ability to sequester carbon dioxide when combined with a polymer known as polyethyleneimine (PEI).

A new study led by scientists at The Scripps Research Institute (TSRI) reveals a key part of the Ebola virus life cycle at a higher resolution than ever before. The research sheds light on how Ebola virus assembles—and how researchers might stop the often-fatal infection. The new study, published online ahead of print today in the journal Cell Reports, builds on previous work in Saphire’s lab showing that a viral protein called...

Chloroplasts, better known for taking care of photosynthesis in plant cells, play an unexpected role in responding to infections in plants, researchers at UC Davis and the University of Delaware have found. When plant cells are infected with pathogens, networks of tiny tubes called stromules extend from the chloroplasts and make contact with the cell’s nucleus, the team discovered. The tubes likely deliver signals from the chloroplast...

Researcher discovers tropical organisms that expel their digestive tracts and rebuild them in 12 days. The vast range of regenerative powers within the animal kingdom has fascinated scientists since the early 18th century. From hydras to planarians and geckos, the remarkable ability of certain species to regrow parts of their bodies and subsequently regain some or all of their original form and function has presented invaluable opportunities...

You might think that young children would first learn to recognize sounds and then learn how those categories of sounds fit together into words. But that isn’t how it works. Rather, kids learn sounds and words at the same time. In fact, the higher-level patterns—those words—are...
