Science writer Michael Greshko partnered with a team of scientists and engineers to explore the spacecraft and mission plans in 'The Martian' novel and movie, down to the rescue plan itself. Incorporating the help of Andy Weir, the novel's author, he comes up with a calendar of events for The Martian, explores the hazards of going back to save Mark Watney, and how a real world interplanetary spacecraft would pull off a rescue maneuver.

International organizers--including Queen's Brian May, an astrophysicist--have organized the world's first Asteroid Day on June 30, as a means to raise awareness for future collision risks and encourage actions to minimize the threats from such events.

Lexus' hoverboard may never become commercially available, but is it scientifically feasible? You'd need to place a superconducting material in a magnetic field powerful enough to support the board and the rider. Steve Gourlay of Lawrence Berkeley Lab's Superconductor Magnet Group provides insights, including the possibility that Lexus put some very strong rare-earth magnets underneath the sidewalk in the video.

A new frontier in data mining: Researchers at the University of Wisconsin-Milwaukee and the Marine Biological Laboratory in Woods Hole, Massachusetts surveyed bacteria from human waste in the municipal sewage systems. Surprisingly they found different proportions of bacterial species in cities that correlated with obesity rates in those municipal areas. The researchers believe that these bacterial samples can yield city-level information on other diseases as well.

Three computer scientists at Stony Brook University in New York believe they have found some rules through a computer program that might predict which fiction books will be successful. Their algorithm had as much as an 84 percent accuracy rate when applied to already published manuscripts in Project Gutenberg and other sources. Among their findings was that more successful books relied on verbs describing thought processes rather than actions and emotions. However, some disagree with the findings. Author Ron Hansen said style is not the key, but instead readers' interest in the topics in the book.

A new study in the journal PLOS ONE suggests that dinosaurs reached gigantic proportions relative to mammals because of differences in their cartilage, making their joints squishier and able to sustain greater amounts of force. Other factors contributed to dinosaurs' larger sizes, including their lighter, air-sac-filled skeletons, and some researchers point out that the sizes of some dinosaurs and mammals were approximately equal, so anatomical differences between cartilage in dinosaurs and mammals may not directly explain why some dinosaurs grew to larger sizes.

The commercially available D-Wave computer, has demonstrated its ability to perform increasingly complex tasks. But is it a real quantum computer? A new round of research continues the debate over how much its calculations owe to exotic quantum-physics phenomena.

When a network is broken — an electrical grid, the World Wide Web, your neurological system — one math model created by a PhD student at Northwestern University suggests that the best way to fix it may be to break it a little more.

Researchers have devised a means of making sound transmit easily through rigid surfaces, including walls. The process relies on creating small holes on a wall, and covering them on one side with a thin covering made from plastic wrap.
