22. Five Tips to Becoming a Killer Scientist Who Changes the World I've been thinking a great deal about how researchers can become better at their craft. Part of their job is to uncover mysteries about the universe. Part of their job is to communicate these ideas to the world. Ignore the latter and your chances of improving the world in some small way becomes miniscule. 22. Five Tips to Becoming a Killer Scientist Who Changes the World

Defending Just-So Stories Last week I spoke about the role of storytelling in science on NPR’s Big Picture Science (the interview won’t air until December). Most people think of story as belonging to the arty world of the humanities—as cut off from the data-driven, hyper-rational world of science. But scientists tell stories all the time. In fact, I think of science as a grand story that emerges—like religion—from our need to make sense of the world. Defending Just-So Stories

Using a refined technique for trapping and manipulating nanoparticles, researchers at the National Institute of Standards and Technology (NIST) have extended the trapped particles' useful life more than tenfold. This new approach, which one researcher likens to "attracting moths," promises to give experimenters the trapping time they need to build nanoscale structures and may open the way to working with nanoparticles inside biological cells without damaging the cells with intense laser light. Scientists routinely trap and move nanoparticles in a solution with "optical tweezers" -- a laser focused to a very small point. The tiny dot of laser light creates a strong electric field, or potential well, that attracts particles to the center of the beam. Although the particles are attracted into the field, the molecules of the fluid they are suspended in tend to push them out of the well.

Gases de los dinosaurios son responsables del aumento de la temperatura global según científicos Gases de los dinosaurios son responsables del aumento de la temperatura global según científicos Los enormes dinosaurios que habitaron la Tierra hace millones de años pudieron haber provocado un calentamiento del planeta con sus gases, producidos al comer diferentes plantas y vegetales, indicaron este lunes científicos británicos. Como las vacas modernas, que emiten una cantidad significativa de metano en su proceso digestivo, estos saurópodos de 20.000 kilos contribuyeron al aumento de la temperatura global, probablemente incluso más que el ganado, indicó el estudio publicado en la revista estadounidense Current Biology. El clima durante la Era Mesozoica, que abarcó 250 millones de años hasta hace unos 65 millones de años, se estima que fue más caliente que el actual. Con voluminosos cuerpos y largos cuellos que permitieron a los saurópodos como el brontosaurio pastar en las llanuras o comer directamente de las copas de los árboles, estas criaturas abundaban hace 150 millones de años, desde unos pocos individuos por kilómetro cuadrado hasta unas pocas docenas en esa superficie.
