More science crowdsourcing games! - "EyeWire" - 4 views

  •  
    There is this optical neuron that gets stimulated from motion. Mapping it is difficult in the lab: "The stumbling block is a lack of fine-grained anatomical detail about how the neurons in the retina are wired up to each other." So, use people deciphering from 2D images --> the 3D neuron structure using the human spatial reasoning to figure out what is part of a branching cell and what is just background noise in the images (yet incomparable to their best algorithms' performance) 120.000 users so far mapped 2% of the retina

Silk protein and chloroplasts for the synthetic leaf - 2 views

  •  
    Royal College of Art's Innovation Design Engineering course in collaboration with Tufts University silk lab. Not as good as it sounds as it does not fully mimic the photosynthesis equation (spare C, H atoms)
  •  
    Interesting stuff and I guess it does not need to fully mimic photosynthesis in the end. As long as oxygen can be produced from CO2 and water that would be great enough. Though the carbon has to be deposited somewhere (in some form) and I wonder how one could extract this efficiently. Maybe it can even serve some purpose (as the sugars are doing for the plant)

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.

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?

Quantum biology: Algae evolved to switch quantum coherence on and off -- ScienceDaily - 3 views

  •  
    Scientists have discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis. The function in the algae of this quantum effect, known as coherence, remains a mystery, but it is thought it could help them harvest energy from the sun much more efficiently. Working out its role in a living organism could lead to advances such as better organic solar cells.
  •  
    very very nice! we tried already a few years back to find an angle to see how we could study quantum phenomena occuring in plants and photosynthsis is one of the great examples since somehow plants manage to make the phenomena work for them at elevated temperatures, a feat in itself ... any good idea most welcome!!!

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.

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

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.

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.

Bio-Derived Porous Carbon Anodes for Li-ion Batteries #Nature - 3 views

  •  
    Here we explore the electrochemical performance of pyrolyzed skins from the species A. bisporus, also known as the Portobello mushroom, as free-standing, binder-free, and current collector-free Li-ion battery anodes. At temperatures above 900 °C, the biomass-derived carbon nanoribbon-like architectures undergo unique processes to become hierarchically porous. Basically they burned a Portobello mushroom and used it as a battery... now thats an multidisciplinary advanced concept

Chicken study reveals evolution can happen much faster than thought - 2 views

  •  
    "A new study of chickens overturns the popular assumption that evolution is only visible over long time scales. By studying individual chickens that were part of a long-term pedigree, the scientists led by Professor Greger Larson at Oxford University's Research Laboratory for Archaeology, found two mutations that had occurred in the mitochondrial genomes of the birds in only 50 years."

Bionic plants: Nanotechnology could turn shrubbery into supercharged energy producers -... - 2 views

  •  
    Plants have many valuable functions: They provide food and fuel, release the oxygen that we breathe, and add beauty to our surroundings. Now, researchers wants to make plants even more useful by augmenting them with nanomaterials that could enhance their energy production and give them completely new functions, such as monitoring environmental pollutants.

Methanotrophs: Could bacteria help protect our environment? - 1 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.
