DNA usually forms the classic double helix shape discovered in 1953—two strands wound around each other. Several other structures have been formed in test tubes, but this does not necessarily mean they form within living cells.

Quadruple helix structures, called DNA G-quadruplexes (G4s), have previously been detected in cells. However, the technique used required either killing the cells or using high concentrations of chemical probes to visualise G4 formation, so their actual presence within living cells under normal conditions has not been tracked, until now.

A research team from the University of Cambridge, Imperial College London and Leeds University have invented a fluorescent marker that is able to attach to G4s in living human cells, allowing them to see for the first time how the structure forms and what role it plays in cells.

The iconic, but bulky, spacesuit worn by Neil Armstrong hasn’t drastically changed in decades. A skintight design may change that.

Spacesuits of the future may resemble a streamlined second skin.

Samsung’s president and head of mobile communications T.M. Roh said in a blog post Monday that Samsung will announce five new products during the company’s big “Galaxy Unpacked” event on Aug. 5.

Samsung didn’t say what it will unveil, but it has teased a new Galaxy Note phone. The company typically unveils its large-screened Galaxy Note devices — best known for the pen that slides into the side — in August. Samsung usually packs in all of the latest hardware and software it has to offer into its Galaxy Note phones ahead of Apple’s iPhone event, which is typically held in September. Rumors suggest this year’s model will be called the Galaxy Note 20.

U.K.-led research team packs more than 200 photonic components onto a chip that performs reconfigurable quantum information processing with light.

Seeing is believing: a little frog (alive!) and a water ball levitate inside a Ø32mm vertical bore of a Bitter solenoid in a magnetic field of about 16 Tesla.

The Sloan Digital Sky Survey (SDSS) released today a comprehensive analysis of the largest three-dimensional map of the universe ever created, filling in the most significant gaps in our possible exploration of its history.

“We know both the ancient history of the universe and its recent expansion history fairly well, but there’s a troublesome gap in the middle 11 billion years,” says cosmologist Kyle Dawson of the University of Utah, who leads the team announcing today’s results. “For five years, we have worked to fill in that gap, and we are using that information to provide some of the most substantial advances in cosmology in the last decade.”
