Two asteroids sped toward Earth but just missed humanity's home planet by what amounts to a cosmic hair's breadth early Wednesday morning. Source: http://xenuth.com/bl...this-wednesday/ It's the prove, that, we wre never safe....

Great Scott, it works! Oh yeah, and the fake stuff works pretty good too.

Are there any useful(or great) websites that teaches you how to use breadboard or shows you the different applications you can apply to a breadboard? (i am not sure if this post belong to this forum, but out of all the other one-this one just seems more suitable.)

I'm not sure if this is the right spot for this question, But what do you think is themost significant scientific discovery or advancement in the last ten years?

In short, a rock from a cliff in Devon was sent 300km high, exposed to the conditions of space, and then brought back down to Earth. It was found that one species had survived the trip - a photosynthetic cyanobactierium. Isolation of Novel Extreme-Tolerant Cyanobacteria from a Rock-Dwelling Microbial Community by Using Exposure to Low Earth Orbit

An interesting paper about how pharma companies sneak marketing aspects into reviews and commentaries. Normally the FDA regulates what can be said about a drug in marketing. However in this report at least one company has been shown to circumvent that by ghostwriting articles that are designed to market their products. Needless to say this is an extremely unethical on so many levels (including also unethical treatment of authorship). Link

Interesting article I came across while viewing sciencedaily.com a few days ago. I thought the stuff was cool and quite critical. I suspect when I get a chance, I'll be looking into the original articles For now, I suspect some of you who like studying modern biology and various aspects of animal/bug psychology and sociology would find this article an interesting read. As follows, there is a link and a bit from the article: http://www.sciencedaily.com/releases/2010/08/100826141221.htm Genomes of Two Ant Species Sequenced: Clues to Their Extraordinary Social Behavior

In this article the authors provide evidence that tetratpod diversity is driven ecologically. So rather due to competition, the diversity was the result of conquering empty niches, a process known as adaptive radiation. Conversely habitat destruction is then likely to be the main element in destroying biodiversity. Sahney, Michael J. Benton, and Paul A.

http://news.stanford.edu/news/2010/august/sun-082310.html How utterly fascinating. I think that finding the 33 day recurring pattern was possibly the oddest part of the whole thing. But how would Neutrinos change the rate anyway?

Tiny cancer-fighting agents are poised to play a big role in the future of chemotherapy. The breast cancer foundation Susan G. Komen for the Cure has awarded a UC Davis researcher $450,000 for the development of nanoparticles capable of effectively targeting and destroying tumor cells while leaving healthy cells unharmed. The grant, given to Dr. Lorenzo Berti, is a part of $3.2 million the foundation plans to invest in California cancer research institutions beginning in 2010. The technology exploits a unique weakness in the blood vessels that feed malignant tumors – they leak. "These blood vessels, unlike normal blood vessels, have big holes in them," sai…

Nicola Cabibbo died on the 16th August 2010. The IOP news article can be found here. The ICTP In Memoriam can be found here.

I am a newly declared neurobiology major, but have profound love for Earth sciences. What kind of magazine subscriptions, online publications, journals, etc. do you recommend in order for me to just, well, keep up with the times? Cho Yung Tea

Dirac's birthday medal for 2010 has been given to Nicola Cabibbo and Ennackal Chandy George Sudarshan, both have made fundamental advances in our understanding of the weak force. The medal is given out annually by the Abdus Salam International Centre for Theoretical Physics (ICTP). Nicola Cabibbo (left) and Ennackal Chandy George Sudarshan See the full Institute of Physics report here. The announcement by the ICTP can be found here.

During last 20-30 years the instruments that explore or probe the surface of ultra-small samples have steadily proliferated. Physicists, chemists, and molecular biologists working in nanoscience have had to familiarize themselves with microscopes that use thermal, magnetic, capacitive, and electrochemical properties. What is next for this amazing family of SPM?

Unbelievable, but it is still known to happen in time of satellites and advanced technology... On the territory of former Yugoslavia, across Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Macedonia, Montenegro, Vojvodina, Kosovo, Serbian Republic, and elsewhere, a new life form was discovered. Although this does not happen often, scientists have succeeded in holding this recent, sensational discovery in secret up until today, when the results of scientific research and analysis finally arrived and confirmed the expectations: various locations of the wider Balkans began to inhabit a new life form. In the professional scientific documentation, the new animal s…

Here is an interesting little piece of information, I'm not sure just how "independent" it is but it seems from the assertion in this article that Cannabis or at least the chemicals in Cannabis including THC suppress cancer... Who knew!? Our government knew and has known for 36 years! http://www.gsalternative.com/2010/05/cannabinoids-kill-cancer/

Mica, a layered mineral with unusual properties could have helped form the template for organic molecules to come together for the formation of life says Helen Hansma of the University of California, Santa Barbara. Mica could have sheltered molecules that were the begining of cells, allowing the non living organic chemcials to come together in ways that helped form life. http://www.sciencedaily.com/releases/2010/08/100806093104.htm

A new combination of nano and solar technology has made it possible for solar electric generation to be cheaper than burning coal. Nanosolar, Inc. has developed a way to produce a type of ink that absorbs solar radiation and converts into electric current. Photovoltaic (PV) sheets are produced by a machine similar to a printing press, which rolls out the PV ink onto sheets approximately the width of aluminum foil. These PV sheets can be produced at a rate of hundreds of feet per minute. "It's 100 times thinner than existing solar panels, and we can deposit the semiconductors 100 times faster," said Nanosolar's cofounder and chief executive officer, R. Martin…

An interesting new study reported in NPR: http://www.npr.org/t...oryId=128490874 So perhaps Churchill's famous saying should be rewritten as "A lie gets halfway around the world before the truth gets its pants on, but the lie is wearing a rather nice minidress and showing lots of cleavage."

In the Science World recently, scientists have discovered microneedls. Needles that are so small when put up against the skin it feels like sandpaper. This revolutionalizes the medicine industry and could began to be mailed out to people as early as in 5 years.

Check out this video. Try listening to the narrator and not notice some obvious scientific flaws, especially the last fifteen seconds of the video. However, it would seem nice if you were able to fill up your car with compressed air at home from a generator, and in the end it would be cheaper than my Jeep Cherokee. It is unfortunate though, that the car design visually is not what some in the ritz would call, "sweet" or "stunning". Anyways lets break this down, I'm curious as to what you guys notice.
