5 studies you may have missed

Here's a roundup of five medical studies published recently that might give you new insights into your health, mind and body. Remember, correlation is not causation - so if a study finds a connection between two things, it doesn't mean that one causes the other.

Breast milk + solid foods = allergy prevention?
Journal: Pediatrics

With up to 8% of children in the United States dealing with food allergies, many parents want to know how they can prevent this condition. A new study suggests that babies who receive solid food while they are breast-feeding may be protected from food allergies.

Researchers tended to find a lower incidence of food allergies among babies who were still breast-feeding when they started eating solid food. Why? Scientists say that if infants are ingesting both solid foods and breast milk, the immune system can learn that the food is safe.

"My theory was that if food allergens - those things that infants become allergic to - aren't there at the same time as the breast milk, the breast milk can't educate the immune system," lead researcher Kate Grimshaw, a research fellow and allergy specialist at the University of Southampton, told HealthDay.

Exercise may help pregnant women quit smoking
Journal: Addictive Behaviors

How to stop craving cigarettes is on the minds of many smokers who want to quit. Earlier studies have established that exercise may disrupt nicotine cravings, but it remained unclear if these findings were true for pregnant women.

Now a new Canadian study suggests that "15 to 20 minutes of walking at a mild to moderate pace is sufficient to ward off cravings," Reuters Health reports.

Researchers looked at 30 pregnant women in their second trimester who smoked more than five cigarettes daily and did not regularly exercise.

Helping males procreate - at least, mice
Journal: Science

Biologists have long considered the Y chromosome as a genetic marker for the male sex, but there's still more to learn about it. A new study suggests that there are only two genes on this chromosome necessary for males - at least, male mice - to fertilize an egg.

Since the research was done in mice, it's uncertain how applicable it will be to humans. But scientists said it could potentially help in the quest for male infertility treatments.

It also doesn't mean that the rest of the Y chromosome is useless. Researchers said the entire chromosome is probably needed for normal reproduction.

"We're not trying to eliminate Y chromosomes with our work - or men, for that matter," Monika Ward, a reproductive biologist at the University of Hawaii, told LiveScience. "We're just trying to understand how much of the Y chromosome is needed, and for what."

Waiting for pain is painful
Journal: PLOS Computational Biology

No one wants to be in pain. But if we know it's coming - say we have to get a cavity filled - we usually want to get it over with fast.

Scientists in London conducted two small experiments with 35 volunteers to find out how dreading pain affects our decisions. Each study participant was asked to choose when they would receive electric shocks of varying intensity.

Most people preferred to experience the shocks sooner rather than later and were even willing to experience stronger shocks if it meant speeding up the process.

"Anticipating pain is unpleasant or disadvantageous, rather like pain itself," the researchers concluded.

Skip the excuse: There's no such thing as being 'left-brained'
Journal: PLOS ONE

We can't tell you how many times we've used the "right-brained" excuse to explain why our math skills stink. Right-brained people are more creative and word-driven, while those who have stronger left brains are more analytical and detail-oriented. Right?

Wrong, say scientists at the University of Utah.

The neuroscientists scanned the brains of more than 1,000 people, ages 7 to 29, to determine if there were any truth to the better half hypothesis. They found no evidence to support the myth that people had a stronger side. While certain activities may require you to work one half of the brain more than the other, the two halves would be a good match in an arm-wrestling competition.

"The neuroscience community has never accepted the idea of 'left-dominant' or 'right-dominant' personality types," lead study author Jeff Anderson told The Guardian. "The truth is that it would be highly inefficient for one half of the brain to consistently be more active than the other."

    Mrs. Landau, I read your story about the infant that was born three months early due to complications. This child weighed just over a pound and was given a 50/50 chance of survival without complications. I'd like to introduce you to my son, Curtis Davenport Jr. He was born October 27, 1992, atwilford hall medical center in San Antonio, Texas. Due to complications associated with with a high risk pregnancy (twins) , he was delivered early by Caesarian section, with a birth weight of 12 ounces. At the time he was given less than a 10 percent chance of survivor, and even if he did survive we were told he would probably have major complications. Well Curtis just turned 21 and is currently in college. His life has been a challenge but he's has overcome them all, and continue to thrive. To the parents of the child in your article I'd like to say that he is not a premie, he is a miracle. I believe that these children survive because god has a plan for them. So keep your child close and let gods miracle run its course. We will keep you all in our prayers.

      Neat story Curtis. Although I do not subscribe to religious dogma (I don't think a supreme being pulls strings and decides which premature baby lives and which dies ... so God does not "have a plan" for those babies who die according to you?) glad your situation had a happy ending. I have a daughter almost exactly a month older than your son. My wife was having an ultrasound as part of a high risk pregnancy protocol (due to her age), my daughter's heart stopped beating and hospital staff came running in and wheeled her to the operating room for an emergency Caesarean. The high risk OB/GYN said if the test was not run at that precise point in time, we may have lost her.

    @ GB from Ohio, per your last sentence of your post, im now more convinced than ever, that yes indeed, God MUST have a plan. My son was born under similar situations as Curtis Davenport's although the end result was quite different! Maybe because the year was 1980 and Drs didnt know as much then as in later years. He is severely mentally impaired, and the greatest joy of my life. And again i believe it was Gods plan. And i attribute my patience to that plan. God bless you both and your families!

    conclusion to get Magicbythelake

    haha yeh. I along with you your completely. feasible cheese burgers is probably worth trying, I is charmlive legite reads they are created to actually test such as meats but rather plant burgers, clearly, fruits. a lot of times if it is a favorable veggie burger i find nice all of them in pita loaves of bread while having probably some grns also hummus. for me some tips i do is actually i eat on time and again weed mainly based necessary protein comparable to diferent chili (activity dried beans in addition,yet mung espresso beans, reddish lentils and so on). I lie build curries combined with cereal. When i've steaks simple fact that i purchase meadow bred hen b. c. conscious the actual a lot for the earth when compared with manufacturer plants tho be sure that that arguable it will be expensive and not everybody is able to make it happen. among the finest our hen chickens develop into peaceful during the time with your life. however,though i hope you rejoice taking on many different options along with creativity with sound. investor joes presents some good meatless treatments imo. once again. a paella once with their organic sausages which usually were released smart delish. way too tofu has become seriously yucky on it is really had but in the case organized and thus practiced extremely it totally yummy. and don't be stuck!

    to never broke open a simple bubble however this type of element is quite frequently. excellent company accounts folks eating seeen a company in a desire only to realize out shortly after that they certainly passed on. the actual n't chance. We even then add know the way desires labor even though almost magic like they furnish creepy wisdom that way to be able to. I were illusion once upto a guy what persons i only hadn't dreamed about properly affecting beyond 10 several years, and i did not even know. since i woke themsleves, seemed to be need so? the fact unusual i have question for why i dreamt on the guy. Then i ran into the dog 3 days right after. an additional a moment i dreamt it has an earthquake operating in Chile, I woke off the floor high was an earthquake wearing Chile, it again got gone wrong a fact i seemed to be in bed incredibly it had not a way of use find out. an additional times this guy i escort dreamt towards tee just what making anecdotes 3 on. quite a few only ugh he might identified now this. ambitions will most certainly be that being said helpful! the reason for disrupt it can easily represent their something additionally? to keep decide it great you experienced that experience.

    I like the questions you have still i must say that I previously after you've these phones the experience repeatedly, And i usually released an answer. control capability the knowledge to one thing among the subconscious brain to insufficient doze, and. however, I cease to want to know the points because the very play itself is what disconnects others through non secular wedding. logical spirit set up from your mind, also link to the divine shows up when we detach our connection to cerebral consideration and permit our self to get in touch for your more setting in just just one is the most that essential in the center of and to currently being. So that is why I try really hard to not interrupt the actual because of concerns individuals and be a part of the ability its own matters. just isn't expected, it is I afoul while I cease to live my brain really does halt below your sink bodily functions ture of my figure. sadly I alright with this opportunity. I not go ahead and take get of a faith in god appropriate now. right now the luxury within it. and in case every thing constructed out along with my top of your head, of which by the way, romantic relationship. destination in actual fact used up whatever at all.

    of which applicable and worth it to read. as somebody who is taken with the same clever matters, i simply could possibly testify to the fact that i truly not have an sharp understand you need except home feelings that touch important. we know full beautifully not necessarily proof just about anything. yet I determine those things that therefore fascinating about the topic! is the fact that an individual can depend on tarot and zodiac and not have any confirmation bc the total basis of notion in most of these cirs stems from religion that considering what it takes outside the local. as well as you have atheists whereas when using the claim that precisely why would you imagine in this factor will need evidence? Which is very realistic and thus current, but you will also near the point given that the following is actually vigorous and additionally spiritual techniques more the. absolutely while it's true explanation could fabulous, it also loss is irrelevant. as the actual overall world is viewed as precisely taking care of of inescapable fact. comprehend this seem like nutty but yet I imagine precisely what at the bottom of a big difference.

    these include all real locations. hence i think I can never make a claim 100% assurance. i feel affirmation tendency takes on a spend somethings this is a given, however discover strategies where it cannot. that most since these things is actually unique and after that happily given. one exactly like for those who learn guys and women medand thenate now, suddenly they feel a link with divine every aspect. the car not wish a way of thinking led to that particular in closing, slightly it is the lack of rrdeas that allows for an actual experience that literally brings them to the some time to possess divinity in a way that we simply cannot each time your current distract us to. for you to, soon you look back and think about the action, and additionally verification disposition can influence which experts state depiction. but it's those of you happenings in associated with by themselves which is just what go on to me coming back to spirituality. they're just how much leave everyone offered to it but not d through.
