| Oh, my stars and hexagons! DNA code shapes gold nanoparticles Posted: 08 Aug 2012 01:32 PM PDT DNA holds the genetic code for all sorts of biological molecules and traits. But researchers have found that DNA's code can similarly shape metallic structures. The team found that DNA segments can direct the shape of gold nanoparticles -- tiny gold crystals that have many applications in medicine, electronics and catalysis. Each of the four DNA bases codes for a different gold particle shape: rough round particles, stars, flat round discs, and hexagons. |
| Hyenas that think outside the box solve problems faster Posted: 08 Aug 2012 01:32 PM PDT Innovative problem solving requires trying many different solutions. That's true for humans, and now Michigan State University researchers show that it's true for hyenas, too. |
| Leveraging bacteria in drinking water to benefit consumers Posted: 08 Aug 2012 09:18 AM PDT Contrary to popular belief, purified drinking water from home faucets contains millions to hundreds of millions of widely differing bacteria per gallon, and scientists have discovered a plausible way to manipulate those populations of mostly beneficial microbes to potentially benefit consumers. |
| Scientists discover the truth behind Colbert's 'truthiness' Posted: 08 Aug 2012 05:13 AM PDT A picture inflates the perceived truth of true and false claims. Trusting research over their guts, scientists in New Zealand and Canada examined the phenomenon Stephen Colbert, comedian and news satirist, calls "truthiness" -- the feeling that something is true. In four different experiments they discovered that people believe claims are true, regardless of whether they actually are true, when a decorative photograph appears alongside the claim. |
