Submission + - Original DOS Boots in Java Applet

Submitted by

Rhys Newman writes: "Oxford Physics Developers have just released a demo version of JPC; a pure Java applet which boots original DOS and can run a selection of classic DOS games. See the JPC homepage for more information and online demo.

JPC emulates all the hardware of a standard PC sufficient to get DOS booting and running classic (or old) software in original form. As the DOS software is running in a completely emulated environment, the standard JVM security model applies and makes JPC a 100% safe environment to run third party x86 untested/unvetted code.

JPC can run on a mobile phone (or any other device which supports a Java 2 VM), and is also intended to enable secure sharing of CPU resources in a computer grid deployment."

Submission + - Angry faces reward teasing behavior

Submitted by martyros
martyros writes: According to a recent study by a psychology study at the University of Michigan, a fleeting look of anger is actually a reward for people with high testosterone levels. In the study, they first measured testosterone levels of the participants, then had the participants perform a "learning task" in which complex key sequences were followed by either an angry face, a neutral face, or no face at all. Participants with high testosterone levels compared to the group learned the key sequence with the angry face faster than the other sequences, while participants with moderate or lower testosterone did not. The effect emerged even more strongly when the angry faces were presented subliminally (i.e., too fast for conscious identification). According to Michelle Wirth, lead author of the study, "Better learning of a task associated with anger faces indicates that the anger faces were rewarding, as in a rat that learns to press a lever in order to receive a tasty treat. In that sense, anger faces seemed to be rewarding for high-testosterone people, but aversive for low-testosterone people."
