Not only are astronauts in danger from cosmic radiation, space junk, catastrophic equipment failure, and their fingernails falling off, they’ve also now got to risk heart attacks for daring to explore that final frontier.
Studies are finding that human hearts change shape and become spherical in space, and microgravity makes astronauts more prone to heart attacks.

Hearts Become Spherical When Astronauts Go To Space: Study
By Lawrence LeBlond | RedOrbit
[…]Previous studies have shown that astronauts are exposed to a range of health issues when taking prolonged trips into space, including losses in bone density and muscle mass and vision anomalies. The new heart health findings, based on a study of 12 astronauts, is to be presented at the upcoming American College of Cardiology’s 63rd Annual Scientific Session.
The new findings bolsters the evidence that even longer periods in space, as would occur on a mission to Mars, is associated with increased dangers on human health. The results of the astronaut study will help scientists better understand how a spaceflight lasting 18 months or longer could affect heart health.
“The heart doesn’t work as hard in space, which can cause a loss of muscle mass,” senior study author James Thomas, MD, Moore Chair of Cardiovascular Imaging and Lead Scientist for Ultrasound at NASA, said in a statement. “That can have serious consequences after the return to Earth, so we’re looking into whether there are measures that can be taken to prevent or counteract that loss.”
In order to keep the heart healthy in space, astronauts will need to know the amount and type of exercise they need to perform to guarantee their safety on prolonged spaceflights. Thomas noted that exercise regimens developed for astronauts could also help people on Earth who have physical limitations also maintain good heart health.

Thomas maintained that the spherical form is only temporary and returns to a normal shape shortly after astronauts return to Earth. But while in space, a spherical shape may mean the heart is performing less efficiently, although long-term health effects are currently unknown.
However, it has been previously found that some astronauts do suffer a variety of cardiac effects upon returning to Earth. Orthostatic hypotension, where the astronaut becomes lightheaded or passes out, occurs when the body experiences a sudden drop in blood pressure when an astronaut tries to stand up. Arrhythmias can also occur during space travel, and there is concern that radiation exposure may accelerate atherosclerosis.

When astronauts go to space, they are not only affected by a loss of muscle mass, but new research shows that their hearts are also at risk, particularly in the fact that they tend to form more spherical shapes while in outer space.

For the study, the researchers trained astronauts to take images of their hearts using ultrasound machines installed on the International Space Station. The 12 participating astronauts provided data on heart shape before, during and after space missions.
The results show that the heart becomes more spherical by a factor of 9.4 percent. This is on board with what scientists had predicted using mathematical models developed for the project. The team believe the models, developed specifically for the study, could also give doctors a better understanding of common cardiovascular conditions for ground-based patients.

Americans’ brains being fried by cell towers: New scientific evidence reveals shocking extent of electropollution damage
by Mike Adams, the Health Ranger
Natural News
Mar 26, 2014
(NaturalNews) Exposure to cell phone towers alters brain function in alarming ways, causing a lack of concentration, irritability, difficulty sleeping and lack of appetite. That’s the conclusion of a new study just published by the British Medical Journal.(1)
The study, authored by Professor Enrique A Navarro, concluded that the severity of such symptoms directly correlated to cell tower exposure levels. In other words, the closer a person lives to a cell tower, the greater the severity of their symptoms. This was true regardless of race, income level and other demographics.
Cell towers, of course, broadcast and receive electromagnetic switching signals. Human biology — and the brain in particular — relies on electro-biochemical pathways for healthy function. Many scientists have long suspected that chronic exposure to low levels of EMF pollution (electropollution) may interfere with healthy functioning of the brain and body. This latest research adds yet more support to that alarming idea.
It’s not your imagination: Electromagnetic hypersensitivity is real
Electromagnetic hypersensitivity has long been dismissed as non-existent by some doctors and industry-funded scientists. After all, if EMF pollution from cell towers really does harm public health, then the implications are truly massive, both economically and in terms of human suffering.
But electromagnetic hypersensitivity is a genuine phenomenon. People are not “inventing” side effects or symptoms. As Navarro writes in the study:
The term electromagnetic hypersensitivity has been recently introduced in discussions attributing symptoms to exposure to EMFs. A review of this topic in 2010 found that 8 of the 10 studies evaluated through PubMed had reported increased prevalence of adverse neurobehavioral symptoms or cancer in populations living at distances < 500 m from [cell phone towers].
Importantly, all these symptoms were recorded in people living near cell phone towers whose broadcast signal strength meets current safety guidelines. As the study author points out, this most likely means current government guidelines on cell phone towers are inadequate to protect the public. Revising such guidelines could have drastic implications for the nationwide telecommunications infrastructure.
By the way, people who live fewer than 500 meters from cell phone towers appear to be especially at risk of electromagnetic interference with brain function. Because electropollution strength is determined by the inverse square of the distance, a person who moves twice as close to a cell tower experiences four times the radiation.
190,000 cell phone towers and growing
There are currently over 190,000 cell phone towers across the United States.(2)
Their typical “maximum range” is over 21 miles, meaning their electromagnetic pollution extends in a sphere with a radius of over 21 miles. (In reality, this pollution extends indefinitely, but the intensity of it drops off with the square of the distance.)
The following map shows AT&T coverage areas in orange. If you live inside an orange area, you are currently exposed to cell tower radiation.
People who live within range of two or more cell phone towers experience electropollution from all the towers within a range of 21 miles. This electropollution effect is cumulative.
It is not known how many Americans live within 21 miles of at least one cell tower, but given that over half the U.S. population lives in urban areas, it’s safe to assume that at least 150 million — and more likely close to 300 million — Americans are exposed to EMF electropollution from cell towers.
Music is your best workout partner
by J.D. Heyes
Natural News
Mar 1, 2014
(NaturalNews) If you’re looking to get the most out of your workouts, no matter what it is that you’re getting set to do — cardio, weightlifting or an intense crossfit session — you might first think about getting your groove on.
In fact, according to various studies, if the music that you listen to fits the rhythm and mood of the physical activity you’re performing, you tend to work out a little harder.
“The metronome aspect, the synchronization of movement to music, is the most important,” Carl Foster, director of the Human Performance Laboratory at the University of Wisconsin at Lacrosse, told The Washington Post.
He went on to say that the notion of synchronizing movement to some sort of beat is not a new concept; in Roman times, rowers aboard galleys moved in concert with the beat of a drum.
Finding what’s right for you
“But there is also the distraction and arousal that music brings,” Foster said, noting that both matter, it’s just not clear to what extent. “There’s definitely more buried in music that affects us. But we don’t know exactly how to tease it out.”
How do you know what the “right” music is for you?
As reported by the Post:
If you want to make a workout mix based on tempo — or BPM, for beats per minute — various Web sites, including www.songbpm.com, can help you determine the tempo of your favorite music to see whether it fits your intended activity. Or you can go to sites such as www.motiontraxx.com that offer playlists at a certain BPM for running and cycling as well as other activities. Other sites include www.workoutmusic.com and www.powermusic.com.
“Music is positive energy,” Deekron “the Fitness DJ” Krikorian, who produces fitness playlists for MotionTraxx, told the paper. “So when I put together playlists, I look for intensity, positive feeling and cohesiveness.”
He says that if he finds a song that feels good in terms of mood and intensity — but it just has the wrong tempo — he may edit it somewhat in order to change the beats per minute to fit the type of exercise.
“The beat becomes very important anytime there is repetitive movement,” Krikorian said. “Our instincts tell us to move to the beat. Our feet tell us to move to the beat.”
As far as what the ideal cadence is for running, that’s a hotly debated topic in the world of running. That’s because we’re not all built alike and we don’t run at the same tempo or stride. That means that finding what’s right for you could take a bit of trial and error.
Some experts say an eight-minute mile generally corresponds with 170 BPM; others say that figure is closer to 200 BPM. Still, others say the ideal running pace is somewhere between 170 and 180. And there are a few studies that indicate that a faster BPM may be better in terms of preventing injury.
Faster is better in some cases
Then again, you could just try some sort of group fitness class instead, such as step aerobics, cardio-kickboxing or cycling. Instructors have been conducting those kinds of classes to musical beats for years.
Ingrid Nelson, a cycling instructor who packs her tempo-driven classes at Washington, D.C.’s Biker Barre, told the Post that intensity, style and cadence are all important when putting together her playlists.
“I like a lot of ’90s hip-hop and usually stay in the range of 95 to 105 BPM,” she said. But she added that she could go as low as 80 BPM or even as high as 120 BPM if she is prescribing hill-climbing or sprints.
Harold Sanco, a group fitness director and instructor at Results gym in the nation’s capital, said that, for some fitness activities like step aerobics, the tempo usually rises to about 130 BPM.
“You have to pick music that is both safe and effective. If you are going too fast, you risk injury and you’re not working out effectively because you are not getting the full range of motion,” he said.

Exciting: Study Reveals How Sleep Removes Toxic Waste from the Brain
by Elizabeth Renter
Natural Society
Feb 20, 2014
(NaturalSociety) Although we don’t know exactly why, there is no question that sleep is crucial for brain and overall health. Without proper sleep, the chance of disease and stress increases notably. Now, researchers at the University of Rochester Medical Center (URMC) Center for Translational Neuromedicine have found that sleeping actually helps detoxify the brain, potentially offering clues into dementia and Alzheimer’s disease.
The study, published in the journal Science, reveals that your brain has a unique method of removing toxic waste through ‘the glymphatic system’. Even more interesting, it seems that brain cells shrink by about 60% during sleep, allowing for waste to be removed more easily.
“Sleep changes the cellular structure of the brain,” said Maiken Nedergaard, co-author of the study. “It appears to be a completely different state.”
How Sleep Aids the Brain
The research looked at something called the glymphatic system of the brain. Injecting dye into the brains of mice, they watched the flow of cerebrospinal fluid (CSF) and found that the CSF flowed rapidly when the mice were unconscious (whether asleep or sedated) and barely moved when the mice were awake.
Melatonin could inhibit breast cancer growth: study
by Reuben Chow
Natural News
Feb 6, 2014
(NaturalNews) A recent study carried out by researchers from Henry Ford Hospital in Detroit and Foundation for Research Support of the State of Sao Paulo has revealed that melatonin, a hormone which regulates the body’s sleep-wake cycle, could help slow the growth of certain types of breast cancer tumors.
Published online in PLoS One, the study suggested that melatonin could inhibit tumor growth and cell production plus block new blood vessels in ER-negative breast cancer models from forming.
Melatonin is a hormone naturally made by the pineal gland, an endocrine gland in the brain. Production of melatonin takes place in the dark and is inhibited by light. Melatonin is also available in supplemental form.
Angiogenesis is the formation of new blood vessels, and one strategy used in slowing the spread of cancer is by blocking this process. For the study, the researchers looked at how melatonin affected angiogenesis in ER-negative breast cancer – they analyzed the association both in vitro and in vivo using mice.
The study team found that the tumors in the mice which were given melatonin for three weeks became significantly smaller and had less vascular growth, while the average tumor volume of the mice not given melatonin increased significantly. The in vitro studies revealed similar findings. In addition, the treated mice displayed excessive movement but neither aggressive behavior nor irritability. They also did not experience lethargy or weight loss.
Scientists Finally Admit There Is a Second, Secret DNA Code Which Controls Genes
The Mind Unleashed
Jan 24, 2014
The fascinating and recent discovery of a new, second DNA code last week further lends credence to what metaphysical scientists have been saying for millennia — the body speaks two different languages.
Since the genetic code was deciphered in the 1960s, researchers have assumed that it was used exclusively to write information about proteins.
But biologists have suspected for years that some kind of epigenetic inheritance occurs at the cellular level. The different kinds of cells in our bodies provide an example. Skin cells and brain cells have different forms and functions, despite having exactly the same DNA.
No Such Thing As Junk DNA
The human genome is packed with at least four million gene switches that reside in bits of DNA that once were dismissed as “junk” but it turns out that so-called junk DNA plays critical roles in controlling how cells, organs and other tissues behave. The discovery, considered a major medical and scientific breakthrough, has enormous implications for human health and consciousness because many complex diseases appear to be caused by tiny changes in hundreds of gene switches.
As scientists delved into the “junk” — parts of the DNA that are not actual genes containing instructions for proteins — they discovered a complex system that controls genes. At least 80 percent of this DNA is active and needed. Another 15-17 percent has higher functions scientists are still decoding.
Recent findings in the journal Science may have big implications for how medical experts use the genomes of patients to interpret and diagnose diseases, researchers said.
The genetic code uses a 64-letter alphabet called codons. Dr Stamatoyannopoulos with co-authors were stunned to discover that some codons, which they called duons, can have two meanings. One describes how proteins are made, and the other instructs the cell on how genes are controlled.
The newfound genetic code within deoxyribonucleic acid, the hereditary material that exists in nearly every cell of the body, was written right on top of the DNA code scientists had already cracked.

Brazilian Scientist: Ayahuasca/DMT Can Effectively Treat Cancer

Activist Post
Jan 30, 2014
Eduardo Schenberg, of the University of Sao Paulo, Brazil, recently published a piece in Sage Journals, detailing his belief that Ayahuasca has cancer-fighting abilities, essentially encouraging the legalization of research in the field.
He says, “There is enough available evidence that Ayahuasca’s active principles, especially DMT and harmine, have positive effects in some cell cultures used to study cancer, and in biochemical processes important in cancer treatment, both in vitro and in vivo,” and “Therefore, the few available reports of people benefiting from Ayahuasca in their cancer treatment experiences should be taken seriously, and the hypothesis presented here, fully testable by rigorous scientific experimentation, helps to understand the available cases and pave the way for new experiments.”
“In summary, it is hypothesized that the combined actions of β-carbolines and DMT present in Ayahuasca may diminish tumor blood supply, activate apoptotic pathways, diminish cell proliferation, and change the energetic metabolic imbalance of cancer cells, which is known as the Warburg effect,” Schenberg wrote. “Therefore, Ayahuasca may act on cancer hallmarks such as angiogenesis, apoptosis, and cell metabolism.”
“If Ayahuasca is scientifically proven to have the healing potentials long recorded by anthropologists, explorers, and ethnobotanists, outlawing Ayahuasca or its medical use and denying people adequate access to its curative effects could be perceived as an infringement on human rights, a serious issue that demands careful and thorough discussion.”
Similar to the way cancer has been successfully treated with cannabis oil, or vitamin B-17 from the apricot pit, it is emerging as a viable possibility that Ayahuasca is another herbal, ancient cure to disease found in abundance in the new world of synthetic consumption.
Ayahuasca, as many viewers of this article likely know, is a psychoactive, ancient, sacred ancient brew, with deep roots in South American shamanic practice. Since at least 500 BC, South American shamans have used Ayahuasca for ceremonial purposes, and as a medicine of many functions.
Many people believe that DMT is created in the pineal gland of human beings when we dream, when we are born, and when we die. Critics of this theory say there is no evidence to back up these claims, but as of 2013, studies from the University of Michigan have shown that indeed dimethyltryptamine is created in the pineal glands of rats, and with the biological similarities us mammals share, it is very likely that DMT is synthesized in our pineal glands as well. According to Dr. Rick Strassman, author of the critically acclaimed book DMT- The Spirit Molecule, the human body metabolizes DMT rapidly, almost eager to consume the substance. Seretonin, the primary source of pleasure for us human beings, created in our brains and bodies daily of course, is 5-hydroxytryptamine, almost chemically identical to dimethyltryptamine. Yet, the US government classifies this molecule that may be part of our very being, as a schedule I, highly illegal drug.
DMT is a very complex substance, with complex experiences had by those who consume it, complex origins, and many, many functions. One must do their own hard research on Ayahuasca and DMT, as explaining a good depth of it would be too much for this article. Many of you who have read this far, probably already know what you need to know about Ayahuasca/DMT, as the popularity of it is skyrocketing.
Adam Winstock, founder of the Global Drugs Survey, claims the drug has ‘a larger proportion of new users’ compared to these other powerful drugs.
He says this suggests ‘its popularity may increase’.
It should be noted that Ayahuasca/DMT has characteristics similar to almost no ‘drugs’ except perhaps psilocybin mushrooms. Psilocin (what psilocybin metabolizes into), is also almost identical to chemicals already in our brains, similarly metabolized quickly by the body, more characteristic of a vitamin than an intoxicant.
