Human genome, twin study, genetic testing
Genome project was completed in 2003, contributions came from Japan, France, Germany, China, and others. Project goals were to identify all 20,000-25,000 genes in human DNA,
determine sequences of the 3 billion chemical base pairs that make up human DNA, store this information in databases, improve tools for data analysis. Imagine how many diseases can be cured from this, never before. A normal gene may be inserted into a nonspecific location within the genome to replace a nonfunctional gene. This approach is most common.
Twins:
By studying twins and siblings and their families, we can estimate how genes and environment interact to influence character, strengths, vulnerabilities and values. Beginning in 2000, the MTFS enrolled an additional 500 pairs of twins and their parents into the MCTFR.

Does parenting really matter?
parents expect you to do certain things or behaviors that please them. They want you to make the right decisions as in not smoking, so even if kids want to smoke, they can't because they have to listen to their parents.

Race, Ethnicity Likely Affects Emotional Well-Being Of Cancer Patients, Study Finds
from Psychology / Psychiatry News From Medical News Today
Black cancer patients report having poorer physical and social well-being than their white counterparts but better emotional well-being, according to a study published in the November issue of the Journal of Pain and Symptom Management, Reuters Health reports. Previous studies have indicated that blacks have poorer physical health than whites.
Sleeping In School
from Psychology / Psychiatry News From Medical News Today
Up to 10% of children starting school suffer from sleep disturbances and these may lead to poor performance or behavioral difficulties. In the current edition of Deutsches Arzteblatt International, the child and adolescent psychiatrist Gerd Lehmkuhl and his colleagues present the results of a study from Cologne, Germany. The authors have as yet interviewed 1388 children starting school and their parents from all parts of Cologne.
Nearly 5 Percent Of The US Population Suffers From Persistent Depression Or Anxiety
from Psychology / Psychiatry News From Medical News Today
Though effective treatments are available for individuals suffering from chronic depression and anxiety, very little is known about how often these treatments are used or how prevalent these conditions are among the nation's general population.

How will Brain Science be used in the future?
We can use brain science to perform neurosurgeries on patients by finding out which brain structure is which. For example, the amygdala is associated with mood/anger so an extremely angry person can have their amygdala removed (idk if this is even possible.) The hippocampus is used for memory, Broca's area for forming speech, Wernicke's area for understanding speech. Angular gyrus for converting images into audio, like if we see a trumpet we'd associate it with music. Also, association areas make us smarter than most animals. Neurons can be computed into a microchip to fly an autopilot airplane. Drug patients can be understood why they act drunk/depressed/hyper because some alcohol/meth can mimic dopamine and seratonin pathways. Also, split brain patients can use their left hand to draw what they see on the right. The left brain's plasticity will fill in the functions of what the right brain would do.

TroopTube: A YouTube for the Military
After banning YouTube, the military launches its own network.
Pay-by-Phone Parking System Launched
Paying for parking by cell means no more fumbling for change.

Archaeologists unearth ruins of ancient church, largest found in Mideast country.
Why a Speeding Shark is Like a Golf Ball
Sharks have mini scales like sandpaper to reduce drags as they move along the water, like how a golf ball has dimples to help speed up the ball.

WATCHING DEATH!
Scientists think death is the end of personal consciousness. Religious people think that their spirits and souls live on. Near-death-experience people claim that they "travel down a long tunnel of light, looking down their body." These are caused by disorganized brain signals while on the verge of dying. The most important experiment that’s never been done is to take fMRI or PET scans of people as they die.

Mouse Party
It surprised me to see a bunch of mice injected with all sorts of drugs to keep them high (hence mouse party, haha.) I selected the mouse with cocaine in it and put it in a centrifuge machine thing. The machine shows the dopamine inside the mouse's brain. Dopamine is responsible for movement, emotion, and attention. With cocaine inside the mouse's body, it blocks the dopamine transporters from receiving dopamine to the neuron. Lacking of dopamine, a person can get Parkinson's disease this way. The mouse's brain is also similar to a human's brain, so if a person consumes cocaine they will not get enough dopamine inside the brain to their body. Also, a person with cocaine cannot control their movements, so they will not stay still.
Heroine mouse: Body's natural opiate blocks the inhibitory receptor so that dopamine can get out freely. This acts as a natural mood-enhancer like sudden overwhelm of happiness or natural painkiller. Heroin users can feel "good" when the heroin mimics natural opiates, making dopamine to flow out and makes a person feel better when in their down times or has an injury. Although frequent use of heroin will lead to depression if not enough dopamines can get out anymore without the heroin's aid.
Meth mouse: Meth mimics dopamine, can get in the neurons. Meth will force dopamines to get out of their vesicles. Excess dopamine are trapped in the synapses. Therefore, those dopamines will overstimulate the cell, making the person feel intense pleasure.
Your iBrain: How Technology Changes the Way We Think
The brain is adapted to change within the environment. An older person might think of newspaper and jazz or R&B music, while a hip and younger person might think of techno, rap and computer. Therefore, the brain only processes what the person has been exposed to the most (mere exposure can work here too.) Also, younger generations have better experience with computers than older generations because they grow up exposed to these sorts of information that older people don't have back then. For example, taking notes can never be easier with advanced electronic notepads. Whereas taking notes the old fashion way on paper might deem useful decades ago, but not anymore. However, a lady with an old, ragged notebook might have a better chance of keeping it longer than a man with his Blackberry phone which one day he will eventually drop and ruin it. Also, the brain has this plasticity that allows it to change information at will to adapt to different environments. For example, a boy who lives on a farm will eventually adapt to the city life, but it takes time.
