Comment Sounds like something I've seen on TV before (Score 1) 107

So what makes the "super sexed" males so, well, sexy and irresistible to the females? Yuval and his team are using a high-protein, bacteria enhanced "stud" breakfast to feed to the males before they're released. The formula should significantly improve their sexual performance.

All natural male enhancement that works? And is legit?

Chevrolet Volt In a Gasoline-Only Scenario 594

Posted by kdawson from the sing-the-auto-electric dept.
s122604 sends in a performance review of the Chevy Volt, paying particular attention to what happens after the initial plug-in capacity has been depleted. This reader adds, "The review indicates that the performance is adequate, and perhaps better than anticipated. If the Volt can deliver technically, especially with the possibility that it could retail for less than expected (WSJ subscription may be required), does GM have a potential hit on its hands?" "How well will General Motors' Chevrolet Volt drive once it gets past its 40 mile all-electric driving range and starts to rely on power generated by its gasoline engine? That's been a question for both critics and fans of the Volt, and with just 11 months to go before this car hits the market, I got the answer."

Ocean-Crossing Dragonflies Discovered 95

Posted by samzenpus from the incredible-journey dept.
grrlscientist writes "While living and working as a marine biologist in Maldives, Charles Anderson noticed sudden explosions of dragonflies at certain times of year. He explains how he carefully tracked the path of a plain, little dragonfly called the Globe Skimmer, Pantala flavescens, only to discover that it had the longest migratory journey of any insect in the world."

Scientists Say a Dirty Child Is a Healthy Child 331

Posted by samzenpus from the snack-is-going-to-be-on-the-floor-today dept.
Researchers from the School of Medicine at the University of California have shown that the more germs a child is exposed to, the better their immune system in later life. Their study found that keeping a child's skin too clean impaired the skin's ability to heal itself. From the article: "'These germs are actually good for us,' said Professor Richard Gallo, who led the research. Common bacterial species, known as staphylococci, which can cause inflammation when under the skin, are 'good bacteria' when on the surface, where they can reduce inflammation."

Misfire can be caused by anything. Thankfully the OBD isolated it down to Cyl 4 (or it thinks its cyl 4). I would start with the simple things like put new spark plugs/wires and clean out the intake first. If that failed, then pay real money to have it diagnosed. Atleast you won't be kicking yourself for paying $100 diagnostic for a $25 part.

Methods of Learning to Build Electronic Circuitry? 134

Posted by Cliff from the beyond-resisters-and-capacitors dept.
Peristaltic asks: "I've seen some cool articles in Instructables detailing how to create various electronic gadgets. A couple of these as well as the odd DIY kit have come to life on my kitchen table. While it's satisfying to see the things work after time spent soldering, I would love to be able to take the next step beyond the basics of component functionality, i.e. a resistor does -this-; a capacitor does -that-. Forest Mimm's books have been helpful towards this end, but it's time to move forward. Every month or so, I read here on Slashdot a plea for help getting started with, or expanding someone's knowledge of programming. OK, I'd like to make that plea for help with electronics theory & circuit building. I've found plenty of references on the web, Amazon, etc., but can someone who's already taken this trip outline what has and hasn't worked for them?"

Submission + - Software Error Likely Killed MGS Spacecraft

Submitted by Aglassis
Aglassis writes: NASA investigators have determined that a software update performed in June of 2006 may have doomed the 10 year old spacecraft. Apparently the software error caused the solar arrays to drive against a mechanical stop which then forced the spacecraft into safe mode. Unfortunately, after that the spacecraft's radiator was pointed at the sun which overheated the battery and destroyed it. Contact was lost with the Mars Global Surveyor spacecraft in November of 2006. NASA will form an internal review board to formally determine the cause of the loss of the spacecraft and what remedial actions are needed for future missions.
