  • often, parents dismiss picture storybooks, especially when they are wordless, as not real reading or just for fun
  • ...9 more annotations...
  • these findings show that reading picture storybooks with kids exposes them to the kind of talk that is really important for children to hear, especially as they transition to school
  • a graduate student, recorded 25 mothers while they read to their toddlers both a wordless picture storybook and a vocabulary book with pictures
  • moms in our study significantly more frequently used forms of complex talk when reading the picture storybook to their child than the picture vocabulary book
  • especially interested in looking at the language mothers use when reading both wordless picture storybooks and picture vocabulary books
  • to see if parents provided extra information to children like relating the events of the story to the child's own experiences or asking their child to make predictions.
  • The results of the study are significant for both parents and educators because vocabulary books are often marketed as being more educationa

  • NASA is sorting through a variety of possible uses for a pair of powerful spy satellite telescopes
  • SA asked scientists to suggest missions for the telescopes, which were donated by the U.S. National Reconnaissance Office (NRO) and are comparable in size and appearance to the famous Hubble Space Telescope.
  • More than 60 serious proposals came

  • in, the most promising of which were presented in early February
  • The two scopes were originally built to carry out surveillance missions under a multibillion-dollar NRO program called Future Imagery Architecture
  • cost overruns and delays killed the program in 2005, and NASA announced in June 2012 that the NRO had bequeathed the instruments to the space agency
  • the telescopes' 8-foot-wide (2.4 meters) main mirrors are comparable to that of Hubble, the NRO instruments are designed to have a much wider field of view
  • Seven big ideas
  • Mars-orbiting space telescope
  • Exoplanet observatory
  • General-purpose faint object explorer
  • Advanced, Hubble-like visible light/ultraviolet telescope
  • Optical communications node in space (which would aid transmissions to and from deep-space assets)
  • Geospace dynamic observatory (which would study space weather and the sun-Earth system)
  • Research of Earth's upper atmosphere (from a spot aboard the International Space Station)
  • Whatever missions NASA ultimately assigns to the NRO scopes, the instruments are a long way from launch
  • they're far from being fully outfitted spacecraft.
  • no instruments on these two telescopes — just primary and secondary mirrors and the support structures

  • Scientists from IBM
  • unveiled the world's smallest movie, made with one of the tiniest elements in the universe: atoms
  • Named "A Boy and His Atom," the Guinness World Records -verified movie used thousands of precisely placed atoms to create nearly 250 frames of stop-motion action.
  • ...11 more annotations...
  • This movie is a fun way to share the atomic-scale world while opening up a dialogue with students and others on the new frontiers of math and science
  • In order to make the movie, the atoms were moved with an IBM-invented scanning tunneling microscope
  • weighs two tons, operates at a temperature of negative 268 degrees Celsius and magnifies the atomic surface over 100 million times
  • IBM Research lab one of the few places in the world where atoms can be moved with such precision.
  • Remotely operated on a standard computer, IBM researchers used the microscope to control a super-sharp needle along a copper surface to "feel" atoms
  • Only 1 nanometer away from the surface, which is a billionth of a meter in distance, the needle can physically attract atoms and molecules on the surface and thus pull them to a precisely specified location on the surface
  • moving atom makes a unique sound that is critical feedback in determining how many positions it's actually moved
  • scientists rendered still images of the individually arranged atoms, resulting in 242 single frames
  • the same team of IBM researchers who made this movie also recently created the world's smallest magnetic bit. They were the first to answer the question of how many atoms it takes to reliably store one bit of magnetic information: 12.
  • it takes roughly 1 million atoms to store a bit of data on a modern computer or electronic device
  • atomic memory could one day store all of the movies ever made in a device the size of a fingernail.

shared by Mars Base on 02 May 13 - No Cached
  • Scientists at Princeton University used off-the-shelf printing tools to create a functional ear that can "hear" radio frequencies far beyond the range of normal human capability
  • primary purpose was to explore an efficient and versatile means to merge electronics with tissue
  • used 3D printing of cells and nanoparticles followed by cell culture to combine a small coil antenna with cartilage, creating what they term a bionic ear.
  • ...17 more annotations...
  • Previously, researchers have suggested some strategies
  • That typically happens between a 2D sheet of electronics and a surface of the tissue
  • our work suggests a new approach—to build and grow the biology up with the electronics synergistically and in a 3D interwoven format
  • Last year, a research effort
  • resulted in the development of a "tattoo" made up of a biological sensor and antenna that can be affixed to the surface of a tooth
  • This project, however, is the team's first effort to create a fully functional organ: one that not only replicates a human ability, but extends it using embedded electronics
  • Creating organs using 3D printers is a recent advance; several groups have reported using the technology for this purpose in the past few months
  • this is the first time that researchers have demonstrated that 3D printing is a convenient strategy to interweave tissue with electronics
  • Ear reconstruction "remains one of the most difficult problems in the field of plastic and reconstructive surgery
  • the team turned to a manufacturing approach called 3D printing
  • The finished ear consists of a coiled antenna inside a cartilage structure
  • Two wires lead from the base of the ear and wind around a helical "cochlea" – the part of the ear that senses sound – which can connect to electrodes
  • further work and extensive testing would need to be done before the technology could be used on a patient
  • the ear in principle could be used to restore or enhance human hearing.
  • electrical signals produced by the ear could be connected to a patient's nerve endings, similar to a hearing aid
  • The current system receives radio waves, but he said the research team plans to incorporate other materials, such as pressure-sensitive electronic sensors, to enable the ear to register acoustic sounds
  • researchers used an ordinary 3D printer to combine a matrix of hydrogel and calf cells with silver nanoparticles that form an antenna. The calf cells later develop into cartilage

shared by Mars Base on 04 May 13 - No Cached
  • Researchers from the German "Loss of the Night" project have developed an app for Android smart phones, which counts the number of visible stars in the sky
  • The data from the app will be used by scientists to understand light pollution on a world wide scale.
  • The smartphone app will evaluate sky brightness, also known as skyglow, on a worldwide scale
  • ...7 more annotations...
  • This data can be used to map the distribution and changes in sky brightness, and will eventually allow scientists to investigate correlations with health, biodiversity, energy waste and other factors
  • The app works by interactively asking users to say whether individual stars are visible. By determining what the faintest visible star is, the researchers learn how many stars are visible at that location, and by extension how bright the sky is
  • With this app, people from around the world can collect data on skyglow without needing expensive equipment
  • some of the testers found that without intending too they learned the names of several stars and constellations
  • is based on the widely used Google Sky Map application
  • development of the app was sponsored by the German Federal Ministry of Research and Education,
  • satellites that observe Earth at night measure the light that is radiating into the sky, not the brightness that is experienced by people and other organisms on the ground
