  • The predator was roughly the size of a wolf, about 6 feet (2 meters) long, and had feathers or hairlike fuzz covering its body to help keep it warm
  • quintessential dinosaur environment, with lots of volcanic activity that periodically inundated the landscape and buried things within it with exquisite preservation
  • apparently dined on a birdlike, cat-size feathered dinosaur known as Sinornithosaurus
  • ...2 more annotations...
  • remains uncertain whether the dinosaurs actively hunted or scavenged these meals
  • the fact that Sinocalliopteryx gobbled at least two birds of the same species at about the same time "says chances are very good it was actively selecting its prey; that makes it a predator

  • A Dutch company that aims to land humans on Mars in 2023 as the vanguard of a permanent Red Planet colony has received its first funding from sponsors
  • Mars One plans to fund most of its ambitious activities via a global reality-TV media event
  • follow the mission from the selection of astronauts through their first years on the Red Planet
  • ...6 more annotations...
  • Receipt
  • Initial sponsors include Byte Internet (a Dutch Internet/Webhosting provider); Dutch lawfirm VBC Notarissen; Dutch consulting company MeetIn; New-Energy.tv (an independent Dutch web station that focuses on energy and climate); and Dejan SEO (an Australia-based search engine optimization firm). [
  • Mars One aims to launch a series of robotic missions between 2016 and 2020 that will build a habitable outpost on the Red Planet. The first four astronauts will set foot on Mars in 2023, and more will arrive every two years after that. There are no plans to return these pioneers to Earth.
  • Mars One estimates that it will cost about $6 billion to put the first four humans on the Red Planet
  • hopes the "Big Brother"-style reality show will pay most of these costs
  • televised action is slated to begin in 2013, when Mars One begins the process of selecting its 40-person astronaut corps

  • Oppy is now moving
  • surveying exposed outcrop in search of phyllosilicate clay minerals that have been detected from orbit
  • What are those rocks made of? How did this feature form? What do the diferent colours and textures mean? These are all questions which the MER team will be hoping to answer over the next few days
  • Opportunity’s solar array energy production is good, producing about 568 watt-hours
  • MER team reports that on Sol 3055 (Aug. 27, 2012), the Rock Abrasion Tool (RAT) on the end of the robotic arm was imaged (top image) to re-confirm the available bit for future grinding and the Alpha Particle X-ray Spectrometer (APXS) collected a measurement of atmospheric argon.

  • Bionic Vision Australia (BVA), a government-funded science consortium, said it had surgically installed an "early prototype" robotic eye in a woman with hereditary sight loss caused by degenerative retinitis pigmentosa
  • pre-bionic eye", the tiny device is attached to Dianne Ashworth's retina and contains 24 electrodes which send electrical impulses to stimulate her eye's nerve cells.
  • device only works when it is connected inside the lab
  • ...6 more annotations...
  • be used to explore how images were "built" by the brain and eye.
  • Feedback from the device will be fed into a "vision processor" allowing doctors to determine exactly what Ashworth sees when her retina is subjected to various levels of stimulation
  • team is working towards a "wide-view" 98-electrode device that will provide users with the ability to perceive large objects such as buildings and cars, and a "high-acuity" 1,024-electrode device
  • high-acuity device are expected to be able to recognise faces and read large print
  • Every time there was stimulation there was a different shape that appeared
  • switched on the device in their laboratory last month after Ashworth had fully recovered from surgery

  • The persistent, dependent use of marijuana before age 18 has been shown to cause lasting harm to a person's intelligence, attention and memory, according to an international research team.

  • psychologist who was not involved in the research, said this study is among the first to distinguish between cognitive problems the person might have had before taking up marijuana, and those that were apparently caused by the drug
  • ...4 more annotations...
  • The study has followed a group of 1,037 children
  • from birth to age 38
  • At age 38, all of the study participants were given a battery of psychological tests to assess memory, processing speed, reasoning and visual processing
  • Friends and relatives routinely interviewed as part of the study were more likely to report that the persistent cannabis users had attention and memory problems such as losing focus and forgetting to do tasks.

  • NASA's Kepler mission has found the first multi-planet solar system orbiting a binary star
  • proves that whole planetary systems can form in a disk around a binary star
  • binary star in question is called Kepler-47
  • ...9 more annotations...
  • primary star is about the same mass as the Sun, and its companion is an M-dwarf star one-third its size
  • inner planet is three times the size of Earth and orbits the binary star every 49.5 days
  • outer planet is 4.6 times the size of Earth with an orbit of 303.2 days.
  • outer planet is the first planet found to orbit a binary star within the "habitable zone,"
  • the planet's size (about the same as Uranus) means that it is an icy giant, and not an abode for life
  • "The challenging thing is that this is a very faint star," Endl said, "about 6,000 times dimmer than can be seen with the naked eye."
  • The secondary star is too faint to measure
  • taking spectra of the system
  • These values, along with the Kepler eclipse and transit timings, were plugged into a model that calculated the relative sizes of all the bodies involved
