  • To learn new motor skills, the brain must be plastic: able to rapidly change the strengths of connections between neurons, forming new patterns that accomplish a particular task
  • if the brain were too plastic, previously learned skills would be lost too easily.
  • A new computational model developed by MIT neuroscientists explains how the brain maintains the balance between plasticity and stability
  • ...31 more annotations...
  • and how it can learn very similar tasks without interference between them.
  • The key
  • is that neurons are constantly changing their connections with other neurons
  • not all of the changes are functionally relevant - they simply allow the brain to explore many possible ways to execute a certain skill, such as a new tennis stroke
  • As the brain learns a new motor skill, neurons form circuits that can produce the desired output
  • according to this theory
  • As the brain explores different solutions, neurons can become specialized for specific tasks
  • brain is always trying to find the configurations that balance everything so you can do two tasks, or three tasks, or however many you're learning
  • Perfection is usually not achieved on the first try, so feedback from each effort helps the brain to find better solutions
  • complications arise when the brain is trying to learn many different skills at once
  • Because the same distributed network controls related motor tasks, new modifications to existing patterns can interfere with previously learned skills.
  • particularly tricky when you're learning very similar things
  • such as two different tennis strokes
  • computer chip,
  • instructions for each task would be stored in a different location on the chip.
  • the brain is not organized like a computer chip. Instead, it is massively parallel and highly connected - each neuron connects to, on average, about 10,000 other neurons
  • That connectivity offers an advantage, however, because it allows the brain to test out so many possible solutions to achieve combinations of tasks
  • neurons
  • have a very low signal to noise ratio, meaning that they receive about as much useless information as useful input from their neighbors
  • The constant changes in these connections,
  • researchers call hyperplasticity
  • balanced by another inherent trait of
  • Most models of neural activity don't include noise, but the MIT team says noise is a critical element of the brain's learning ability
  • This model helps to explain how the brain can learn new things without unlearning previously acquired skills
  • the paper shows is that, counterintuitively, if you have neural networks and they have a high level of random noise, that actually helps instead of hindering the stability problem
  • Without noise, the brain's hyperplasticity would overwrite existing memories too easily
  • low plasticity would not allow any new skills to be learned, because the tiny changes in connectivity would be drowned out by all of the inherent noise
  • The constantly changing connections explain why skills can be forgotten unless they are practiced often, especially if they overlap with other routinely performed tasks
  • skills such as riding a bicycle, which is not very similar to other common skills, are retained more easily
  • Once you've learned something, if it doesn't overlap or intersect with other skills, you will forget it but so slowly that it's essentially permanent
  • researchers are now investigating whether this type of model could also explain how the brain forms memories of events, as well as motor skills

  • NASA's Hubble Space Telescope has
  • spotted water vapor above the moon's frigid south polar region, providing the first strong evidence of water plumes erupting off the moon's surface
  • Scientists had previously detected evidence of an ocean under Europa's icy crust
  • ...12 more annotations...
  • the simplest explanation for this water vapor is that it erupted from plumes on the surface of Europa
  • If those plumes are connected with the subsurface water ocean
  • then this means that future investigations can directly investigate the chemical makeup of Europa's potentially habitable environment without drilling through layers of ice
  • This would actually be the second moon in the solar system known to have water vapor plumes
  • The first one to be discovered was Saturn's moon Enceladus
  • First detected in 2005 by NASA's Cassini orbiter, the plumes also possess dust and ice particles
  • So far, though, only water vapor gases have been detected in Europa.
  • It's possible that these plumes could be vented from long cracks on Europa's surface
  • Cassini has actually seen similar fissures that host the Enceladus
  • Europa plumes are similar to Enceladus in another way. They seem to also vary depending on the moon's orbital position; active jets have only been seen when Europa is farthest from Jupiter
  • supports a key prediction that Europa should tidally flex by a significant amount if it has a subsurface ocean
  • Once the plumes are confirmed, scientists can take a closer look at their composition and may even be able to find out more about the potential subsurface sea of Europa

  • groundwater scientists were very well aware of the presence of the freshwater reserves beneath the seafloor, but have assumed it to occur during unusual and extraordinary situations
  • this latest study reveals that the fresh and brackish aquifers under the seabed are a common phenomena
  • formed hundreds to thousands of years ago when the sea level was lower than what it is currently
  • rainwater penetrated into the ground and filled up the water tables in regions that are currently under sea
  • Nearly 20,000 years ago, the sea levels rose, the ice caps began melting and the areas were covered by oceans
  • Most of the aquifers today are protected from seawater by blankets of clay and sediments that are piled on top
  • These aquifers are not different from those found below land. Their salinity is low due to which they can be easily converted into drinking water
  • researchers propose two ways to gain access to these freshwater reserves
  • either be by constructing a platform and drilling into the seabed, which is expensive
  • Or drill from the mainland that is at a closer distance from the aquifer
  • Freshwater under the seabed is much less salty than seawater
  • it can be converted to drinking water with less energy than seawater desalination
  • also leave us with a lot less hyper-saline water
  • freshwater offshore should remember is that the water reserves are non-renewable and should be used carefully
