Methanotrophs: Could bacteria help protect our environment? - 0 views

  •  
    New method for geoengineering?

    New insight into methanotrophs, bacteria that can oxidise methane, may help us develop an array of biotechnological applications that exploit methane and protect our environment from this potent greenhouse gas. Publishing in Nature, scientists led by Newcastle University have provided new understanding of how methanotrophs are able to use large quantities of copper for methane oxidation.

Earth's extremes point the way to extraterrestrial life - 0 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."

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."

Surprising similarity in fly and mouse motion vision - 1 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."

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.

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."

Medical Xpress: Newly discovered hormone mimics the effects of exercise - 0 views

  •  
    "Hormones are molecules that act as the body's signals, triggering various physiological responses. The newly discovered hormone, dubbed "MOTS-c," primarily targets muscle tissue, where it restores insulin sensitivity, counteracting diet-induced and age-dependent insulin resistance."

    Good news for long distance space travelers?

Nature Optics: Super vision - 6 views

  •  
    Taking images through opaque, light-scattering layers is a vital capability and essential diagnostic tool in many applications.

    The research group of Prof. Mosk of U. Twente have started doing experiments shooting optical lasers into opaque materials in 2007, and for surprise of everyone, it turn out the light intensity after the opaque material in their experiments was orders of magnitude bigger than expected.

    Following these results they succeeded in taking non-invasive sharp pictures of objects hidden behind a screen of opaqueness, the so referred Super Vision in this Nature overview article.

Octopus robot makes waves with ultra-fast propulsion - 2 views

  •  
    Technology/Robotics Scientists have developed an octopus-like robot, which can zoom through water with ultra-fast propulsion and acceleration never before seen in man-made underwater vehicles. Most fast aquatic animals are sleek and slender to help them move easily through the water but cephalopods, such as the octopus, are capable of high-speed escapes by filling their bodies with water and then quickly expelling it to dart away.

Meet the electric life forms that live on pure energy - 3 views

  •  
    Unlike any other living thing on Earth, electric bacteria use energy in its purest form - naked electricity in the shape of electrons harvested from rocks and metals. We already knew about two types, Shewanella and Geobacter. Now, biologists are showing that they can entice many more out of rocks and marine mud by tempting them with a bit of electrical juice. Experiments growing bacteria on battery electrodes demonstrate that these novel, mind-boggling forms of life are essentially eating and excreting electricity.

Mystery of where Earth's water came from deepens: Comet water is different - 2 views

    "Over the past few months, the European Space Agency's Rosetta space probe closely examined the type of comet that some scientists theorized could have brought water to our planet 4 billion years ago. It found water, but the wrong kind."

Brain's reaction to virtual reality should prompt further study, suggests new research - 2 views

  •  
    "Neuroscience UCLA neurophysicists have found that space-mapping neurons in the brain react differently to virtual reality than they do to real-world environments. Their findings could be significant for people who use virtual reality for gaming, military, commercial, scientific or other purposes."

    I wonder if we are doing it wrong with the airplane pilot simulators...

Brain decoder can eavesdrop on your inner voice - 4 views

  •  
    "As you read this, your neurons are firing - that brain activity can now be decoded to reveal the silent words in your head TALKING to yourself used to be a strictly private pastime. That's no longer the case - researchers have eavesdropped on our internal monologue for the first time. The achievement is a step towards helping people who cannot physically speak communicate with the outside world."

    Or alternatively, a step towards snooping into individuals' privacy.

    Soon we'll be able to see movies about our dreams!

    Only if you are willing to have a chip implanted into/onto your brain though ^^
