New Study Brings Scientists Closer to the Origin of RNA

(Phys.org) —One of the biggest questions in science is how life arose from the chemical soup that existed on early Earth. One theory is that RNA, a close relative of DNA, was the first genetic molecule to arise around 4 billion ...

Engineers build biologically powered chip

Columbia Engineering researchers have, for the first time, harnessed the molecular machinery of living systems to power an integrated circuit from adenosine triphosphate (ATP), the energy currency of life. They achieved this ...

Decoding a key part of the cell, atom by atom

Whatever you are doing, whether it is driving a car, going for a jog, or even at your laziest, eating chips and watching TV on the couch, there is an entire suite of molecular machinery inside each of your cells hard at work. ...

Beewolves protect their offspring with antibiotics

Digger wasps of the genus Philanthus, so-called beewolves, house beneficial bacteria on their cocoons that guarantee protection against harmful microorganisms. Scientists of the Max Planck Institute for Chemical Ecology in ...

Synthetic biology moves into the realm of the unnatural

The field of synthetic biology has had great success engineering yeast and bacteria to make chemicals—biofuels, pharmaceuticals, fragrances, even the hoppy flavors of beer—cheaply and more sustainably, with only sugar as ...

Cocaine synthesized in a tobacco plant

A team of researchers at the Chinese Academy of Sciences, working with a colleague from Syngenta Jealott's Hill International Research Centre in the U.K., has developed a way to synthesize cocaine using a tobacco plant. The ...
