Black Hole Emits a 1,000-Light-Year-Wide Gas Bubble 145

PhrostyMcByte writes "12 million light-years away, in the outer spiral of galaxy NGC 7793, a bubble of hot gas approximately 1,000 light-years in diameter can be found shooting out of a black hole — one of the most powerful jets of energy ever seen. (Abstract available at Nature.) The bubble has been growing for approximately 200,000 years, and is expanding at around 1,000,000 kilometers per hour."

Scientists Say a Dirty Child Is a Healthy Child 331

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."

Submission + - Swarms of Solar Powered Microbots On the Way (

Mike writes: "Researchers are currently developing ways to mass produce tiny solar-powered robots that operate like swarms of insects to collect data to aid in surveillance, micromanufacturing, medicine, and more. Measuring in at under 4mm square, these microbots have all the equipment necessary to move, communicate, and collect data, plus they generate all of their own power via solar panels. If the team is able to find a way to efficiently mass produce the miniscule autonomous bots they stand to revolutionize the future of data collection."

Submission + - False news from yahoo (

sherms writes: "Yahoo's scoop! How many times has your business suffered because you trusted the wrong person? If you're like most people, you've been lied to thousands of times. Deception hurts in many ways. There's the emotional stress from being betrayed, the loss of self-confidence and the increased suspicion or even paranoia. Not to mention the financial cost. Bull Crap! The ways they list are bogus over approx. 70% of the time. I was a cop for over 20 years and was taught by one the top interrogators in the United States (who interviewed Ted Bundy, and many others). This article is a load of hype. It it completely exaggerated and prejudice. Apparently this person has not had to get a confession out of some one on different med's or drugs. He apparently has never heard of ADD, or OCD. He needs to read Gavin D. Beckers "The gift of Fear". It just sounds like he is trying to make a name for himself since he was with the CIA. I really wish the reporter would have checked a second and third source. I think he would find out his story is very one sided. /b?"
