If 40-80% of BMI comes from genes, then 20-60% comes from somewhere else

possibly tell how much of someone's weight is due to genes? And how much is due to life style choices? One way scientists try to pick apart genetic and environmental causes is to study sets of identical twins. Identical twins have the same DNA but can be put in different environments. This lets scientists directly tell what is due to genetics and what is due to genes. For example, in one study of obesity, sets of identical twins were fed extra food and forced to behave similarly (same amount of exercise, eating, etc.). During the study both twins in an identical twin pair gained about the same weight. But there were huge differences in the amounts of weight gained between sets of twins. This kind of study tells us that the tendency to gain more or less weight is in our genes. But twin studies can also show that some aspects of weight have to do with behavior too. For instance, scientists looked at identical twin pairs that exercised different amounts. As expected, the twin that exercised more weighed less. This shows that weight is not just genetic and that behavior is not all genetic. The fact that the twins had different exercise patterns definitely suggests that what we weigh has a large environmental component. So how much we weigh has to do with both our genes and our behavior. Just because someone's parents are heavy that does not mean their children will be heavier too. But it might mean that they will have trouble keeping the weight off. Good exercise habits and eating healthy foods can help maintain a normal weight. The opposite is also true. Your genes can predispose you to be normal weight. But if you eat too much food and do not exercise enough to use up the extra energy, then you will gain weight and eventually become overweight. Weight is really just a product of energy taken in (food you eat) minus energy used (for exercise, for heating our bodies, for helping digest our food, etc). So to lose weight, all you have to do is use more energy than you eat. And to gain weight, you just have to eat more food than you use up. Sounds simple, right? But of course it isn't--partly because of genes. Our genes can affect the amount of weight lost from dieting and exercise. They can also affect how much weight is gained when we eat too much. Our genes make proteins that work together to control everything from how often we get hungry to how we use energy from food. They even control how much exercise we can do at a time. Because our genes tell our bodies how to handle the food we eat, it's often hard for us to achieve a certain target weight. But what we weigh isn't only due to our genes.

considered to be multifactorially inherited

Multifactorial inheritance means that "many factors"

where a combination of genes from both parents, in addition to unknown environmental factors, produce the trait or condition

factors are usually both genetic and environmental

Often, one gender (either males or females) is affected more frequently than the other in multifactorial traits

means that one gender is more likely to show the problem

Slightly more males develop schizophrenia in childhood, however, by adolescence schizophrenia affects males and females equally.

Although schizophrenia affects men and women equally, symptoms in men generally begin earlier than in women

schizophrenia first appears in men during their late teens or early 20s

women, schizophrenia often first appears during their 20s or early 30s.

schizophrenia affects 2.7 million Americans

child born into a family with one or more schizophrenic family member has a greater chance of developing schizophrenia than a child born into a family with no history of schizophrenia.

chance for a sibling to also be diagnosed with schizophrenia is 7 to 8 percen

If a parent has schizophrenia, the chance for a child to have the disorder is 10 to 15 percen

Risks increase with multiple affected family members.

Distorted perception of reality (i.e., difficulty telling dreams from reality) Confused thinking (i.e., confusing television with reality) Detailed and bizarre thoughts and ideas Suspiciousness and/or paranoia (fearfulness that someone, or something, is going to harm them) Hallucinations (seeing, hearing, or feeling things that are not real such as hearing voices telling them to do something) Delusions (ideas that seem real but are not based in reality) Extreme moodiness Severe anxiety and/or fearfulness Flat affect (lack of emotional expression when speaking) or inability to manage emotions Difficulty in performing functions at work and/or school Exaggerated self-worth and/or unrealistic sense of superiority of one's self Social withdrawal (severe problems in making and keeping friends ) Disorganized or catatonic behavior (suddenly becoming agitated and confused, or sitting and staring, as if immobilized) Odd behaviors

The symptoms of schizophrenia are often classified as positive (symptoms including delusions, hallucinations, and bizarre behavior), negative (symptoms including flat affect, withdrawal, and emotional unresponsiveness), disorganized speech (including speech that is incomprehensible), and disorganized or catatonic behavior (including marked mood swings, sudden aggressive, or confusion, followed by sudden motionlessness and staring).

diagnosed by a psychiatrist

Specific treatment for schizophrenia will be determined by your physician based on: Your age, overall health, and medical history Extent of the disease Your tolerance for specific medications, procedures, or therapies Expectations for the course of the disease Your opinion or preference

Types of treatment that may be helpful to an individual with schizophrenia may include: Medications (also called psychopharmacological management; to reduce the symptoms of schizophrenia), including the following: Neuroleptics--a specialized class of medications used to treat schizophrenia. Neuroleptics are used primarily to treat the pervasive, intrusive, and disturbing thoughts of a person with schizophrenia. They are designed to help minimize the severity of delusions and hallucinations the individual is experiencing. Antipsychotic medications--medications that act against the symptoms of psychotic illness, but do not cure the illness. However, these medications can reduce symptoms or reduce the severity of symptoms; a specialized class of medications used to treat schizophrenia. Individual and family psychotherapy (including cognitive and behavioral therapy) Specialized educational and/or structured activity programs (i.e., social skills training, vocational training, speech and language therapy) Self-help and support groups

Preventive measures to reduce the incidence of schizophrenia are not known at this time

ested the learning abilities of sleeping newborns by repeating tones that were followed by a gentle puff of air to the eyelids.

After about 20 minutes, 24 of the 26 babies squeezed their eyelids together when the tone was sounded without the puff of air.

The brain waves of the 24 infants were found to change, providing a neural measurement of memory updating.

While past studies find this type of learning can occur in infants who are awake, this is the first study to document it in their most frequent state, while they are asleep

Learned eyelid movement reflects the normal functioning of the circuitry in the cerebellum, a neural structure at the base of the brain. This study's method potentially offers a unique non-invasive tool for early identification of infants with atypical cerebellar structure, who are potentially at risk for a range of developmental disorders, including autism and dyslexia, she said.

Newborn infants' sleep patterns are quite different than those of older children or adults in that they show more active sleep where heart and breathing rates are very changeable," she said. "It may be this sleep state is more amenable to experiencing the world in a way that facilitates learning."

Another factor is that infants' brains have greater neural plasticity, which is the ability for the neural connections to be changed

"If you're trying to lose weight, getting enough sleep gives you a fighting chance."

“We worry a lot about zoonoses, the transmission of diseases from animals to people,” said Christiane Loehr, a professor at the OSU College of Veterinary Medicine. “But most people don’t realize that humans can also pass diseases to animals, and this raises questions and concerns about mutations, new viral forms and evolving diseases that may potentially be zoonotic. And, of course, there is concern about the health of the animals.”

H1N1 (“swine flu“) and H5N1 (“bird flu”)

The first recorded instance, described in an article published by the team in Veterinary Pathology, took place in Oregon in 2009.

While a cat owner was hospitalized with H1N1, both of her cats (which stayed indoors and had no contact with other sick people or animals) came down with flu-like symptoms and eventually died. A postmortem analysis of their lungs and nasal cavities turned up the H1N1 virus

“It’s reasonable to assume there are many more cases of this than we know about, and we want to learn more,” Loehr said.

“Any time you have infection of a virus into a new species, it’s a concern, a black box of uncertainty,” Loehr noted.

this news might trigger immediate concern,

the flu could be passed from human to pet, mutate into a more dangerous form,

“We don’t know for sure what the implications might be, but we do think this deserves more attention.”

infants would be looking at their mothers constantly because that was common knowledge within [the field of] social cognition with infants." But in a room full of toys scattered everywhere and obstacles to climb on and crawl on, the infants only looked toward their mothers about half the time.  And even if they did look at their mothers, they looked at their mothers' faces only about 15 percent of the time.

toddlers almost always look directly at the object when reaching for it.

Toddlers are able to use information from their peripheral vision and still walk very well.

Another interesting finding was that while infants look directly at an obstacle before walking onto or over it, 75 percent of the time they don't always have to.

According to Franchak, down the line it could offer more research applications that could help infants with developmental disorders, medical research and applied research.   

The CDC (center for disease control) has permitted boiling of needles and medical tools for an hour in extreme cases in areas where autoclaves and other more functional methods are not available.

“Once Mischel began analyzing the results, he noticed that low delayers, the children who rang the bell quickly, seemed more likely to have behavioral problems, both in school and at home. They got lower S.A.T. scores. They struggled in stressful situations, often had trouble paying attention, and found it difficult to maintain friendships. The child who could wait fifteen minutes had an S.A.T. score that was, on average, two hundred and ten points higher than that of the kid who could wait only thirty seconds.” - Jonah Lehrer from his piece in the New Yorker, “Don’t”

Interestingly, these results suggest that although almost everyone has problems with procrastination, those who recognize and admit their weakness are in a better position to utilize available tools for precommitment and by doing so, help themselves overcome it. - Dan Ariely, from his book “Predictably Irrational”

first birthdays, babies start shifting back to look you in the eye again

University of Iowa psychology professor Bob McMurray, who also studies speech development.

quality face-time with your tot is very important for speech development – more than, say, turning on the latest baby DVD.

Other studies have shown that babies who are best at distinguishing between vowel sounds like "ah" and "ee" shortly before their first birthday wind up with better vocabularies and pre-reading skills by kindergarten.

babies also look to speakers' faces for important social cues about what they're hearing

So he and doctoral student Amy Hansen-Tift tested nearly 180 babies, groups of them at ages 4, 6, 8, 10 and 12 months. How? They showed videos of a woman speaking in English or Spanish to babies of English speakers. A gadget mounted on a soft headband tracked where each baby was focusing his or her gaze and for how long.

They found a dramatic shift in attention: When the speaker used English, the 4-month-olds gazed mostly into her eyes. The 6-month-olds spent equal amounts of time looking at the eyes and the mouth. The 8- and 10-month-olds studied mostly the mouth.

At 12 months, attention started shifting back toward the speaker's eyes.

at 6 months, babies begin observing lip movement, Lewkowicz says, because that's about the time babies' brains gain the ability to control their attention rather than automatically look toward noise.

This study clarifies the mechanism and function of memory in various dissociative states and helps explain why trauma might result in the development of alters.

In addition to raising the public profile of the disorder, the book also marked the first suggestion that alternate personalities were created as a way to wall off traumatic memories of physical or sexual abuse, and that those memories could be recovered with the help of a therapist.

The idea at the time was that the mind locks these memories away, but with the help of a therapist, and through hypnosis or the use of drugs like Sodium Pentothal, these memories could become accessible,

Called a “concealed information task,” the test’s goal is ostensibly simple: identify words as they flash on a computer screen. If one of a small set of randomly selected “target” words appears, press yes. For all other words, press no. The catch, McNally said, is that while many of the words hold no meaning for the patients, a small subset of the non-target words are taken from two autobiographical questionnaires patients fill out at the start of the test — one while inhabiting one personality, the second in another.

When one of those personally relevant words — such as a best friend’s name, favorite food, or favorite sport — appears on screen, McNally said, most patients’ first impulse is to press the yes button. Within moments, however, they realize the word doesn’t appear on the target list, and they eventually give the “correct” answer by pressing no.

All participants showed a nearly identical lag for words that were relevant to their alternate personalities, McNally said, suggesting that the information wasn’t locked away in a separate identity.
