It's Getting Hot in Here

A lot has been said in the last decade about the issue of global warming with some people (idiots) believing it is not even real.  Last month broke a 16-month streak of months where the temperatures have been above average.  In America things are getting the hottest in the region of the Great Plains.  The states of the Great Plains are currently in a drought that shows no signs of getting better any time soon.  Things have become so bad that on October 17 and 18 there was a big dust storm that caused the states of Colorado, Nebraska, Oklahoma, Kansas, and Wyoming to close major highways.

Planting conditions were highly effected by the Dust Bowl as well as many other things.  The mounds of dust as you see in the picture above where not the only terrible things that came from the Dust Bowl.  Scientists have said that if the drought doesn't get better in another two or three years then we could soon find the Great Plains are in another Dust Bowl.  This time there might not be these big dust storms sweeping across the area but the effects on farming conditions and plants would be hard to overcome.  Farmers have said they believe that they will be able to get through this Dust Bowl if it happens but it would require technological advances to help them.

The Mind of a Rapper

Many people give no respect to rappers or people of the urban culture in pop culture because they see them as dumb or ignorant when in fact they might be some of the more creative people in the world because of what they can do with an instrument or with words.  Neurologists have recently decided to study the creative flow that these people have due to their ability to come up with rhymes out of nowhere at any time.  They have used fMRI's (functional magnetic resonance images) on rappers while they are doing a freestyle to try to observe the blood flow and get a better understanding of where this creativity comes from.  Neurologists compared the fMRI results from freestyle rapping of 12 rappers with raps they had written down.

They found that during a freestyle the medial prefrontal cortex, which corresponds with self-motivation and initiation, as well as the emotional and and motor regions were more active during the freestyle raps more so than the written raps.  Siyuan Liu, the lead researcher said she believes that these different regions all become linked in a network when someone is doing a freestyle.  At the beginning of a phrase the they noticed the left side of the brain was more active but as they neared the end of the phrase the right side became more active.  This is odd but it is believed to be this way because they have to think about the words and language at the beginning (left brain) and think more and the music at the end (right brain).  These studies can be very important in helping to understand what factors in to creativity and trying to use those factors to everyone's advantage.

Drummin to the Brain's Beat

Since the 1920s it has been known that the brain has its own rhythm of electrical activity that were known as brain waves but new studies done by University of California neuroscientist Adam Gazzaley with the help of Grateful Dead drummer Mickey Hart have shown that this rhythm can be so much more.  They believe, with some evidence to support, that the rhythm of the brain could be the cause of, and the solution to diseases in the brain such as Alzheimer's, which Hart's grandmother dealt with.  Hart noticed that she could communicate better when he played the drums and that's when he decided to connect with Gazzaley and take part in this study.

In the last twenty years they have found that rhythm can be a factor in perception, attention, working memory, and learning.  That means that certain beats you hear can affect the way you learn or the way you look at things.  Music is now much more important than ever before because it can help someone with a brain disease hopefully recover a little bit.  It has already been shown that rhythm can reduce seizures in rodent models of epilepsy and they hope that this is no where near the end of what changing and messing with the rhythm of peoples' brains can do.  The hope is that music can be a real medicine for people with brain disease.

Ear Power

Taking power for a living organism is not a new thing for scientists and researchers to do but recently they have discovered how to take the inner ear of a guinea pig and use it for energy and sensory purposes.  Usually scientists use enzymes to transform catalytic energy into electric energy but this new way apparently just "steals" energy that the body produces by itself.  The cochlea of the inner ear converts sound pressure waves into electrical waves that are sent to the brain so you can process what it is you are hearing.  The new chip that the scientists came up with just takes out that electrical energy without disturbing the hearing of the organism.

Scientists from Harvard and MIT connected electrodes to the fluids in the cochlea.  They connected these electrodes to small sensors right outside the guinea pigs ear and took about 1 nanowatt.  These sensors are small enough to put in humans but the energy extracted is not enough to power a device to help with deafness.  Scientists have previously been using biofuel cells, creating energy from blood glucose but this energy doesn't last forever like the energy from the ear would.  The ultimate goal is to gain knowledge about how and why people have deafness and possibly to help cure the diseases of the ear.
