Testing Neurons With Ultrasound [+ video]
Turning certain brain cells on and off with light — a technique called optogenetics — is one of the most important tools in neuroscience. It allows scientists to test basic ideas about how brains work. But because waves of visible light don’t penetrate living tissue well, the technique requires the insertion of a conduit for…

Study adds to evidence that viruses may be alive
A new analysis supports the hypothesis that viruses are living entities that share a long evolutionary history with cells, researchers report. The study offers the first reliable method for tracing viral evolution back to a time when neither viruses nor cells existed in the forms recognized today, the researchers say.

That Stinky Cheese Is a Result of Evolutionary Overdrive
Like many biologists, Ricardo C. Rodríguez de la Vega searches the world for new species. But while other scientists venture into the depths of the ocean or the heart of the jungle, Dr. Rodríguez de la Vega and his colleagues visit cheese shops.

The man who wants to beat back aging
On a blazingly hot morning this past June, a half-dozen scientists convened in a hotel conference room in suburban Maryland for the dress rehearsal of what they saw as a landmark event in the history of aging research. In a few hours, the group would meet with officials at the U.S. Food and Drug Administration…

The theory of parallel universes is not just maths – it is science that can be tested
The existence of parallel universes may seem like something cooked up by science fiction writers, with little relevance to modern theoretical physics. But the idea that we live in a “multiverse” made up of an infinite number of parallel universes has long been considered a scientific possibility – although it is still a matter of…
