DNA may be one of the most basic molecules of life, but it's not easy to study. Despite being a very long molecule, it's only about 2.2 nanometers wide, so it's hard to see. Attaching fluorescent dyes to it can help, but until now, knowing how those dye molecules were behaving wasn't possible. A team of scientists at Stanford University has built on a technique called "single-molecule microscopy" to see just how DNA-bound dye molecules orient themselves, flop around and glow in the presence of polarized laser light.

An unmanned Cygnus cargo ship left the International Space Station today, and then NASA set it on fire. At 4:55 pm EDT, ground control activated the Saffire-I experiment in the hold of the Orbital ATK Cygnus Pressurized Cargo Module as it drifted away from the station, triggering the largest fire ever started in space. The controlled burn inside an insulated container is part of a study to learn more about the nature of fire in zero gravity and improve spacecraft safety...

SpaceX founder and CEO Elon Musk has never made a secret that he wants to go to Mars, and soon. Plans for an unmanned landing in 2018 using a Red Dragon capsule were announced earlier this year, and now in an interview with the Washington Post the tech entrepreneur has given a broad outline of a proposal that could see a manned mission touching down on the Red Planet in 2025...

The latest attempt by SpaceX to land a Falcon 9 booster on a sea barge ended in what founder and CEO Elon Musk called a "rapid unscheduled disassembly." After three successful sea landings in a row by the company, the unmanned rocket impacted on the deck of the droneship "Of Course I Still Love You" at 10:37 am EDT after successfully sending its payload of two communications satellites into orbit. According Musk, the fiery crash was due to an engine malfunction... Continue Reading Falcon 9 landing ends in "rapid unscheduled disassembly" (Translation: it crashed)

If there's one place in our solar system you would expect to be as frozen solid as a box of forgotten ice lollies, it would be Pluto. However, PhD student Noah Hammond at Brown University says that data returned in 2015 by NASA's unmanned New Horizons deep-space probe indicates that the dwarf planet may have a subsurface ocean similar to those suspected to exist on some moons of Jupiter and may be responsible for the unusual surface features...
