Animal brains connected up to make mind-melded computer - 2 views

  •  
    Parallel processing in computing --- Brainet The team sent electrical pulses to all four rats and rewarded them when they synchronised their brain activity. After 10 training sessions, the rats were able to do this 61 per cent of the time. This synchronous brain activity can be put to work as a computer to perform tasks like information storage and pattern recognition, says Nicolelis. "We send a message to the brains, the brains incorporate that message, and we can retrieve the message later," he says. Dividing the computing of a task between multiple brains is similar to sharing computations between multiple processors in modern computers, "If you could collaboratively solve common problems [using a brainet], it would be a way to leverage the skills of different individuals for a common goal."

Why is life left-handed? The answer is in the stars - 2 views

  •  
    While most humans are right-handed, our proteins are made up of lefty molecules. In the same way your left and right hands mirror one another, molecules can assemble in two reflected structures. Life prefers the left-handed version, which is puzzling since both mirrored types form equally in the laboratory.

Earth's extremes point the way to extraterrestrial life - 1 views

  •  
    Seems a little speculative but pretty interesting thoughts. In regards to terraforming Mars this might be of interest: "During the daytime, plant-like microorganisms on a Martian-like surface could photosynthesize hydrogen peroxide. At night, when the atmosphere is relatively humid, they could use their stored hydrogen peroxide to scavenge water from the atmosphere, similar to how microbial communities in the Atacama use the moisture that salt brine extracts from the air to stay alive."

Surprising similarity in fly and mouse motion vision - 2 views

  •  
    Loosely related to an old ACT project on optical flow (if I remember correctly but even if not still an interesting read I think): "At first glance, the eyes of mammals and those of insects do not seem to have much in common. However, a comparison of the neural circuits for detecting motion shows surprising parallels between flies and mice. Scientists have learned a lot about the visual perception of both animals in recent years."

Sentinel-2 catches eye of algal storm - 0 views

  •  
    The Sentinel-2A satellite has been in orbit for only a matter of weeks, but new images of an algal bloom in the Baltic Sea show that it is already exceeding expectations. Built essentially as a land monitoring mission, Sentinel-2 will also certainly find its way into marine applications.

Introducing A Brain-inspired Computer [IBM TrueNorth] - 0 views

  •  
    Built in Silicon technology (Samsung's 28 nm process), its power is measured as one million neurons and 256 million synapses. It contains 5.4 million transistor being the largest IBM chip in these terms. All this said, it consumes less than 100 mW!! "These systems can efficiently process high-dimensional, noisy sensory data in real time, while consuming orders of magnitude less power than conventional computer architectures." IBM is working with initLabs to integrate the DVS retinal camera with these chips = real time image neuro-like image processing. In what seems to be a very successful project hugely funded by DARPA, "Our sights are now set high on the ambitious goal of integrating 4,096 chips in a single rack with 4 billion neurons and 1 trillion synapses while consuming ~4kW of power."

Chemical analysis in Earth and Space via Raman Spectroscopy - 2 views

  •  
    "A new lightweight, energy-efficient tool for analyzing a material's chemical makeup could improve the detection abilities of various technologies, ranging from bomb-detecting drones to space rovers searching for signs of life". Raman Spectroscopy is about measuring vibrational modes in molecules. This vibrational modes are in the meV typically, turning Raman Spectroscopy into a high precision technique. This impressive work shows a new technique based on the use of optical fibers coupled to photomultipliers allowing its use, author's word, in extreme conditions such as unmanned aircraft vehicles (UAVs) and Mars/Moon rovers.

How Acupuncture Pierces Chronic Pain - ScienceNOW - 0 views

  • Millions of people worldwide use acupuncture to ease a variety of painful conditions, but it’s still not clear how the ancient treatment works. Now a new study of mice shows that insertion of an acupuncture needle activates nearby pain-suppressing receptors. What’s more, a compound that boosts the response of those receptors increases pain relief—a finding that could one day lead to drugs that enhance the effectiveness of acupuncture in people.

'Doomsday Ark' to be Housed on the Moon -A Remote Access Toolkit to Rebuild the Human Race - 5 views

  • our future may reside on the Moon if plans.being drawn up for a “Doomsday ark” on the moon by the European Space Agency are carried through.
  • whether living organisms could survive, European Space Agency scientists are hoping to experiment with growing tulips on the moon within the next decade.
  • would initially be run by robots
  •  
    did not know ESA was doing that!
  •  
    too late, the world will in end in 2012 ......... I fail to see in which scenario this would be better than a couple of vaults on Earth (since there would be no humans on the moon). But if tulips on the moon can convince politicians, I'm all for it.
  •  
    "The first flowers - tulips or arabidopsis, a plant widely used in research - could be grown in 2012 or 2015 according to Bernard Foing, chief scientist at the agency's research department." - Bernhard strikes again :-)

Flights of fancy - 1 views

  • Could quantum entanglement help a flock of birds fly south for the winter? A team of scientists at the Akademie der Wissenschaften and the Universität Innsbruck, both in Austria, is looking at how concepts central to the field of quantum information—entanglement and coherence—play a role in the chemistry of magnetodetection that animals use for navigation.

Lotus Plant-Inspired Dust-Busting Shield To Protect Space Gear - 3 views

  • replicate to prevent dirt from accumulating on the surfaces of spacesuits, scientific instruments, robotic rovers, solar array panels and other hardware used to gather scientific data or carry out exploratory activities on other objects in the solar system
  • The team also is trying to partner with Northrop Grumman to add a biocide to the coating, which would kill bacteria that thrive and produce foul odors wherever people are confined to a small space for long periods, like the space station.
  •  
    We had some discussion about the Lotus-effect roughly two years ago. Zoe said that NASA surely worked on it. Well, she was right.
