The human brain has the same general structure as the brains of other mammals, but is larger than any other in relation to body size. The human brain is almost twice as large as the brain of the bottle-nose dolphin, and three times as large as the brain of a chimpanzee. Much of the expansion comes from the part of the brain called the cerebral cortex, especially the frontal lobes, which are associated with executive functions such as self-control, planning, reasoning, and abstract thought. The portion of the cerebral cortex devoted to vision is also greatly enlarged in humans.
Here we are presenting 9 different studies carried out about human brain at different parts of world which might give you a few insights of human brain.

Postpartum Depression Affects 1 In 7 Mothers
It's well documented that some women suffer depression after having a baby. But it's less well-known just how many do.
by PATTI NEIGHMOND
The largest study to date shows that as many as 1 in every 7 women suffers postpartum depression. And the study, published in the journal JAMA Psychiatry, finds that among women followed for a year after delivery, some 22 percent had been depressed.
The study also recommends that all pregnant women and new mothers be screened for depression.
Ten-thousand women who delivered infants at one obstetrical hospital in Pittsburgh were asked to take part in a short telephone interview four to six weeks after they had their babies.
"We asked them whether they had been able to laugh and see the funny side of things," says University of Pittsburgh psychiatrist Dorothy Sit, who was one of the study investigators. Sit says researchers also asked about the new mothers' "ability to look forward with enjoyment to things, whether or not they're blaming themselves necessarily when things go wrong, feeling anxious or worried for no good reason, being scared or panicky for no good reason."

Sperm are healthier in winter and early spring
While it’s not clear why sperm are healthier in the winter, researchers theorize that semen is affected by warm temperatures, daylight exposure, and hormone variations.
If you’re trying to have a baby, a new study suggests that it’s best to try in winter and early spring, when men have healthier sperm.
Israeli scientists studied samples from more than 6,000 men who were being treated for infertility between January 2006 and July 2009.
According to the Daily Mail, researchers found sperm in greater numbers, with faster swimming speeds, and fewer abnormalities, in semen made during the winter -- which could account for the boom in childbirths in autumn. The sperm declined steadily in quality from spring onwards, the report says.

What not to use in the bedroom
A new study finds that women who use petroleum jelly such as Vaseline vaginally can put themselves at risk for a common infection called bacterial vaginosis.
Prior studies have already linked douching with a host of ill effects, including bacterial vaginosis, but not much research has been done on how petroleum jelly affects female sexual organs.
Lead researcher Dr. Joelle Brown of the University of California, San Francisco, and her colleagues recruited 141 women in the study, with half of the women saying they had used some type of sexual lubricant, petroleum jelly, or baby oil vaginally in the past month.
When the researchers tested the women for infections, they found that those who'd used petroleum jelly in the past month were more than twice as likely as non-users to have bacterial vaginosis.
While the illness doesn’t cause long-term problems, it can be uncomfortable, and worse puts a woman at greater risk of sexually transmitted diseases.
Your best bet: reach for water soluble products designed specifically as a vaginal lubricant, which are both safer and more cosmetically pleasing.

Chemotherapy backfires - causes healthy cells to feed growth of cancer tumors
by Mike Adams, the Health Ranger
Editor of NaturalNews.com
(NaturalNews) Ever since chemotherapy was introduced into the practice of western medicine, doctors and oncologists have been trying to answer this nagging question: Why does chemotherapy seem to work at first, but then cancer tumors cells grow back even more aggressively while the body becomes resistant to chemotherapy?
It turns out that chemotherapy damages healthy cells, causing them to secrete a protein that accelerates the growth of cancer tumors. (http://ca.news.yahoo.com/chemotherapy-backfire-boost-cancer-growth-st...)
This protein, dubbed "WNT16B," is taken up by nearby cancer cells, causing them to "grow, invade, and importantly, resist subsequent therapy," said Peter Nelson of the Fred Hutchinson Cancer Research Center in Seattle. He's the co-author of the study that documented this phenomenon, published in Nature Medicine.

Type 2 Diabetes Information - the most common form of diabetes in adults
Type 2 diabetes is the most common form of diabetes in adults.
Until a few years ago, type 2 diabetes was rare in children, but it is becoming more common, especially for overweight teens.
According to the U.S. Centers for Disease Control and Prevention (CDC), one in three American children born after 2000 will develop type 2 diabetes in his or her lifetime.
Type 2 diabetes affects the way the body is able to use sugar (glucose) for energy.
It is recommended that students displaying or possibly experiencing the risk factors and warning signs associated with type 2 diabetes be screened (tested) for the disease.

Type 2 diabetes affects the way the body is able to use sugar (glucose) for energy.
- The body turns the carbohydrates in food into glucose, the basic fuel for the body’s cells.
- The pancreas makes insulin, a hormone that moves glucose from the blood to the cells.
- In type 2 diabetes, the body’s cells resist the effects of insulin, and blood glucose levels rise.
- Over time, glucose reaches dangerously high levels in the blood, which is called hyperglycemia.
- Hyperglycemia can lead to health problems like heart disease, blindness, and kidney failure.
It is recommended that students displaying or possibly experiencing the risk factors and warning signs associated with type 2 diabetes be screened (tested) for the disease.
Drug Crazed - USA
When a man in Miami chewed off a homeless man's face last year a little-known drug was blamed. This report investigates how 'bath salts' are wreaking havoc across the USA as the number of addicts grows.
"It's robbed him of a life. It's taken his soul." Tiffany Russell watches footage of her 24-year-old son Skyler, a bath salts addict. Unable to help her son herself, Tiffany feels the Government have failed him by pondering for too long over what to do about the drug.
"When they finally did something, it's too late for the thousands who have been affected." But it's a battle that's far more complex, explains Drug Enforcement officer Jim Burns. "New York State passed a bath salts law a year ago. No sooner had they passed it, some enterprising chemist somewhere tweaked the chemical formula.
Now it's no longer the substance that was banned in the state law. So we're back to square one."

What Is Fibromyalgia Syndrome (FMS) and is it treatable?
Fibromyalgia is a disorder that causes muscle pain and fatigue (feeling tired). People with fibromyalgia have “tender points” on the body. Tender points are specific places on the neck, shoulders, back, hips, arms, and legs. These points hurt when pressure is put on them.
Fibromyalgia is the most common musculoskeletal condition after osteoarthritis. Still, it is often misdiagnosed and misunderstood. Its characteristics include widespread muscle and joint pain and fatigue as well as other symptoms. Fibromyalgia can lead to depression and social isolation.
This overview of fibromyalgia syndrome (FMS) covers symptoms, diagnosis and treatment, and the impact fibromyalgia has on lives. The impact comes from the tremendous physical and psychological strains that come with FMS. Those strains can lead to loss of work hours, reduced income, and even job loss.

Analysis: Antibiotic apocalypse - is the end nigh?
A terrible future could be on the horizon, a future which rips one of the greatest tools of medicine out of the hands of doctors.
A simple cut to your finger could leave you fighting for your life. Luck will play a bigger role in your future than any doctor could.
The most basic operations - getting an appendix removed or a hip replacement - could become deadly.
Cancer treatments and organ transplants could kill you. Childbirth could once again become a deadly moment in a woman's life.
It's a future without antibiotics.
Even for sperm, there is a season: study
Autumn is the time of year most associated with bumper crops of new babies, and according to an Israeli study there may be a scientific reason for it: human sperm are generally at their healthiest in winter and early spring.
Based on samples from more than 6 000 men treated for infertility, researchers writing in American Journal of Obstetrics & Gynecology found sperm in greater numbers, with faster swimming speeds and fewer abnormalities in semen made during the winter, with a steady decline in quality from spring onward.“The winter and spring semen patterns are compatible with increased fecundability and may be a plausible explanation of the peak number of deliveries during the fall,” wrote lead researcher Eliahu Levitas from Ben-Gurion University of the Negev in Beer-Sheva.
If there is a seasonal pattern, they said, that knowledge may “be of paramount importance, especially in couples with male-related infertility struggling with unsuccessful and prolonged fertility treatments.”

Aspartame - fears of cancer and premature birth link
A leading British expert, Professor Millstone, has called for an investigation into serious health concerns over the artificial sweetener aspartame – after the EU food watchdog insisted it was safe.
The European Food Safety Authority has published a draft scientific opinion effectively rubbishing more than 20 studies which have identified potential problems with the sweetener, ranging from premature births to cancer.
The authority’s view will be welcomed by manufacturers who use aspartame and similar sweeteners in fizzy drinks such as Diet Coke, and diet foods consumed by millions of people every day.
Professor Millstone suggested that the EFSA panel that carried out the assessment was dominated by experts linked to manufacturers or regulators that have previously supported aspartame.
‘Of the 17 members of the EFSA panel, seven have direct commercial conflicts of interest, and another five have institutional conflicts of interest, for example, because their employers have already announced that aspartame is safe’ he said.

Three minutes a week High Intensive Training (HIT) can change your life
London - So far, I have spent 43 years on this planet. But I don’t think my heart has ever beaten faster than it is now. I’m on a bike at the gym. My face is red, my body is limp, my heart feels like it is making an escape attempt.
Yet all I’ve done is cycle for 30 seconds.
What makes my cycling unusual - and garners strange glances from the woman on the treadmill behind me - is the intensity of my exercise. I’ve put every ounce of my being into going as fast as I possibly can. I am thrashing at the pedals so hard that the bike is rattling like a pneumatic drill. I’m pleased the machine is nailed to the floor.
I’m here to check out one of the most fascinating areas of health research.
Current advice from the NHS suggests that in order to stay healthy, adults should take either 150 minutes - that’s two-and-a-half hours - of “moderate” exercise a week, or 75 minutes of “vigorous” exercise.
But a growing number of studies - from proper scientists, not wacky weirdos - suggest that the benefits of exercise could be achieved in much less time if you go in for very short bursts of very high-intensity exercise.
How short? Well, just one minute, three times a week. Yes, you read that correctly. Three minutes a week. Those three minutes can be split into six bursts of 30 seconds over the week, or nine bursts of 20 seconds. But they must be totally full-on.

Scientists Prove DNA Can Be Reprogrammed by Words and Frequencies
We came across this article today and thought that it would be a great read for our viewers. It’s awesome information showing the true nature of our reality and how science is changing everyday, opening up to the possibilities of this reality.
“Scientist Prove DNA Can Be Reprogrammed by Words and Frequencies"
By Grazyna Fosar and Franz Bludorf
THE HUMAN DNA IS A BIOLOGICAL INTERNET and superior in many aspects to the artificial one. Russian scientific research directly or indirectly explains phenomena such as clairvoyance, intuition, spontaneous and remote acts of healing, self healing, affirmation techniques, unusual light/auras around people (namely spiritual masters), mind’s influence on weather patterns and much more. In addition, there is evidence for a whole new type of medicine in which DNA can be influenced and reprogrammed by words and frequencies WITHOUT cutting out and replacing single genes.
