Submission + - Supercritical Fuel Results in 30% MPG Increase (greencarreports.com)

thecarchik writes: A flurry of innovations to boost fuel efficiency is in the pipeline. One of them comes from a startup, Transonic Combustion, which claims its technology delivers fuel into the cylinder in a supercritical state--essentially, a fourth state of matter (after solid, liquid, and gas) in which the liquid is heating above its boiling point at very high pressure. When gasoline is injected into the cylinder as a supercritical liquid, Transonic says, it burns faster, cleaner, and closer to the center of the combustion chamber, meaning less energy is wasted as heat loss through the cylinder walls.

Submission + - Firefox 4 to Force HTTPS Connections (threatpost.com)

Trailrunner7 writes: In an effort to help mitigate man-in-the-middle attacks that make normal HTTP connections look like secured HTTPS sessions, Mozilla is adding support in Firefox 4 for a new technology called HTTP Strict Transport Security that enables site operators to tell browsers to always request an HTTPS session on future visits.

The technology, which is also known as ForceTLS, is currently an IETF draft specification and Mozilla officials say it should give users more confidence in HTTPS connections over time. Right now, the existence of HTTPS in front of a URL in a browser's address bar is nothing close to a guarantee that the connection is actually a secure one. There are myriad man-in-the-middle attack scenarios that introduce a high level of uncertainty for SSL connections.
