El DNA: secreto de vida.

Interesante esfuerzo de digitalización de todos los documentos publicados por los primeros científicos-investigadores. Muchos años después de los estudios de Watson y Crick, sus primeras descripciones de la estructura de doble hélice, han sido mostrados y compartidos con todos nosotros. Un lujo.

Dogs that keep close contact with children during their first months of life, will behave more properly afterwards.

Fake: The tree octopus that researchers fabricated to test the evaluation skills of students

When it comes to the Internet, it seems kids will believe anything.
But it was thought that something as absurd as an octopus that lives in a tree might be enough to cast some doubts in their minds - it wasn't.
A creature concocted in a research 'laboratory' has exposed shocking Internet illiteracy among students, with a leading expert warning it could mean a learning crisis in schools.
Donald Leu, a researcher from the University of Connecticut, conducted a study among the Facebook generation of students - deemed 'digital natives' due to their online savviness - to try to prove they will believe anything they read on the internet.
He directed students to the website http://zapatopi.net/treeoctopus, where they found details about the fabricated endangered Pacific Northwest tree octopus in order to test students’ ability to evaluate information they find online.
It detailed the creature's appearance and habits, including how it uses its suckers to move along tree branches in a form of 'locomotion' and steals eggs from the nests of birds.
It even claimed that it was endangered mainly due to the penchant of wealthy 'fashionistas' to use the tree octopuses as ornamental hat decorations.
The students not only believed all of the fabricated information, but also insisted on the existence of the octopus, even when researchers explained all the information had been made up.
Mr Leu, founder and director of the New Literacies Research Lab at the university, warned that students were unable to discern between fact and fiction online and said this would lead them to graduate without the proper thinking skills needed to meet college and workforce demands.

He said : 'Most students simply have very little in the way of critical evaluation skills.

Ellos te dirán que no se creen todo lo que leen en internet, pero lo hacen. Esto debe ser motivo de gran preocupación. Cualquiera puede publicar cualquier cosa en internet y los estudiantes de hoy en día no están preparados para evaluar con espíritu crítico la información encontrada.

He also claimed that among the students who do depend on search engines for research, many do not know how to use the results.
'Typically, students will click on the first listing at the top of the results page and take a quick look, then continue down the list without studying the source of the website to figure out whether it’s the best source of information,' he said.
'Often they pass right by the website they should be looking at because it doesn’t look like the website they have in their mind.
'The challenge is we’re not preparing kids in the classroom for these new online reading skills. If kids are largely going to use the Internet now and in the future, these skills for online comprehension must be included in what teachers teach.'
'That’s what children do with their rock stars and their other cultural stars. They are accustomed to typing in the name and adding .com. That often doesn’t work for real academic research.'

PASADENA, Calif. -- NASA's Kepler mission has discovered its first Earth-size planet candidates and its first candidates in the habitable zone, a region where liquid water could exist on a planet's surface. Five of the potential planets are near Earth-size and orbit in the habitable zone of smaller, cooler stars than our sun.
  "In one generation we have gone from extraterrestrial planets being a mainstay of science fiction, to the present, where Kepler has helped turn science fiction into today's reality,"
