A new electron beam device uses metal feed stock to create parts without molding or cutting. From the article: "The beam melts the wires and applies them carefully on top of a rotating plate to build an object up slowly, layer by layer." This is a huge step for space travel, but it also gives us a great short-term reason to invest in space stations and moon bases for manufacturing satellite and rocket parts. Very exciting!

Any thoughts?

Scientists have finally uncovered the genetics that allow spiders to create their ultra-fine and strong silk that could one day replace current surgical adhesives. http://www.newscientist.com/article/mg20427325.200-sticky-future-for-the-spider-suture.html

In an encouraging development, an investigational vaccine regimen has been shown to be well-tolerated and to have a modest effect in preventing HIV infection in a clinical trial involving more than 16,000 adult participants in Thailand. Following a final analysis of the trial data, the Surgeon General of the U.S. Army, the trial sponsor, announced today that the prime-boost investigational vaccine regimen was safe and 31 percent effective in preventing HIV infection.

This clearly cannot compete with threads about melons, but for those involved or interested in science careers this is a nice viewpoint regarding funding situations. The interesting thing is that it is almost universally valid. http://www.plosbiology.org/article/info%3Adoi%2F10.1371%2Fjournal.pbio.1000197 One of the many nice quotes in the text: Edit: shoot. I meant science careers in the title, of course.

There is an experiment in its infancy that needs scientists of all fields to contribute. Drawn from the works of the late Carl Sagan, the State of the Species Experiment asks the question, “How should society be structured to facilitate the peaceful and rapid advancement of the species?” Check it out at http://www.stateofthespecies.org

http://www.npr.org/templates/story/story.php?storyId=113139754 " When Bill Sparkman told retired trooper Gilbert Acciardo that he was going door-to-door collecting census data in rural Kentucky, the former cop drawing on years of experience warned: "Be careful." The 51-year-old Sparkman was found hanged from a tree near a Kentucky cemetery and had the word "fed" scrawled on his chest, a law enforcement official said Wednesday, and the FBI is investigating whether he was a victim of anti-government sentiment..."

Now who of you just ran out to get some watermelon? Yes? Yes? show of hands? Eating watermelon has a similar effect on the body to Viagra, according to researchers in the US. It's down to a chemical called citrulline which is found in the juicy fruit. ... Citrulline is an organic compound which affects the body's blood vessels in the same way as the sex enhancement pills. http://news.bbc.co.uk/newsbeat/hi/health/newsid_7498000/7498061.stm

This article is actually an essay and also about a year old. However, I found myself pulling it out every so often to show it to new grad students. Essentially, is you do not feel stupid doing what you are doing, you are not trying hard enough. http://jcs.biologists.org/cgi/content/full/121/11/1771

http://dsc.discovery.com/news/2009/09/18/glove-writing.html From the article: A fingerless bike glove equipped with electrical sensors lets you write on thin air, according to new research. The modified glove could not only allow for discreet, one-handed text messaging but also create an early warning system for neurodegenerative diseases like Parkinson's ... Placing the patches over the major muscle groups in the hand and lower arm, the researchers recorded the time and strength of the impulse and input the data into a computer program. Now that's pretty neat! Beyond the application as early detection of neurodegenerative diseases, this has huge app…

Hallo! Ich war gestern im Casino und habe den ganzen Tag roulette gespielt und das eigentlich sehr erfolgreich. Ich hab da mehr auf gut glück gespielt, aber eigentlich ist es doch auf einen tisch recht simple zu gewinnen wenn man einfach eine taktik spielt: Man setzt zb. jedes Mal nur auf rot. Beim 1. mal setzt man 5 euro Bei Verlust, setzt man 10 euro Falls man wieder verliert 20;40;80;160 Die Wahrscheinlichkeit, dass in 6 Runden 1x die Farbe rot mindestens einmal kommt, ist doch sehr hoch oder? Also mit dem System kann man dann praktisch ja nur gewinnen, bei einer 50/50/1 wahrscheinlichkeit ist das ja sehr wahrscheinlich. Habt jemand einen Plan?

All these years of reading threads on SFN where monopoles are proclaimed to be impossible... and here they are. I'm now curious to see if someone else will overturn the claims or if their conclusions are…
