The public supports most traffic safety laws. They routinely defy cell phone laws, believing that they should be pulled over for driving recklessly, not for having a cell phone, and they defy speed limits - but nothing like when the onerous national 55 MPH speed limit was forced on society - yet for the most part, road safety laws are obeyed. People stop at stop signs.

Yet a new survey shows how to strengthen road laws; quantify the traffic-related injury risks associated with a given law.

Astronomers have discovered clear skies and steamy water vapor on a planet known as HAT-P-11b - outside our solar system. HAT-P-11b is about the size of Neptune, making it the smallest exoplanet ever on which water vapor has been detected. 

HAT-P-11b is a so-called exo-Neptune, a Neptune-sized planet that orbits another star. It is located 120 light-years away in the constellation of Cygnus (The Swan). Unlike Neptune, this planet orbits closer to its star, making one lap roughly every five days. It is a warm world thought to have a rocky core, a mantle of fluid and ice, and a thick gaseous atmosphere. Not much else was known about the composition of the planet, or other exo-Neptunes like it, until now.

A 1997 Food and Drug Administration (FDA) rule allowed food manufacturers to use ingredients "generally regarded as safe," or GRAS, like vinegar and lots of other things, without needing approval all over again.

Food advocates say the current GRAS process allows substances into the food supply that might pose a health risk. How can safe products be risky?

In the future, new organs will be created from a patient's own stem cells and they will require no waiting lists, no immunosuppressive drugs, and no stickers on drivers licenses making people available for organ donations.

Currently, organ transplantation is "opt in" - you have a choice. A new paper by psychologists examines whether it might be better to have organ donation be opt-out.

How people perceive and taste alcohol depends on genetic factors, and that influences whether they "like" and consume alcoholic beverages, according to a nutritionist
and colleagues at Penn State's College of Agricultural Sciences.

The iPhone 6 is apparently flexible, though that's a not a good thing; people are warping them when they sit down, and people without abnormal strength can simply twist them in their hands.

But that won't always be a design and construction defect. As tech company LG demonstrated this summer with the unveiling of its 18-inch flexible screen, the next generation of roll-up displays is tantalizingly close.
