Has Cancer Been Completely Misunderstood?

A Failed War On Cancer Sayer Ji, Green Med InfoEver since Richard Nixon officially declared a war on cancer in 1971 through the signing of the National Cancer Act, over a hundred billion dollars of taxpayer money has been spent on research and drug development in an attempt to eradicate the disease, with trillions more spent by the cancer patients themselves, but with disappointing results.Even after four decades of waging full-scale “conventional” (s [...]

Journal Verifies That the Vaccinated Are Transmitting Disease

Dave Mihalovic, Prevent DiseaseOfficials at the U.S. Centers for Disease Control and Prevention (CDC) say the best way to prevent pertussis is to get vaccinated. However, more data continues to present itself suggesting that may be completely false. A new study published in BMC Medicine by Santa Fe Institute Omidyar Fellows Ben Althouse and Sam Scarpino points to a different, but related, source of the outbreak — vaccinated people who are infectious but who do not dis [...]

Raw Garlic Twice a Week Can Reduce Risk of Cancer by 40%

Marco Torres, Prevent DiseaseCompounds within garlic produce reactive oxygen species in cancer cells, activating of multiple death cascades and blocking pathways of tumor proliferation. Eating garlic just twice per week reduces cancer risk without any side effects whatsoever.The reason so many people die with conventional cancer treatment is that while damaging healthy cells, chemotherapy also triggers them to secrete a protein that sustains tumour growth and resistance to [...]

Think the Anti-GMO Movement is Unscientific? Think Again

Sayer Ji, Green Med Info“Anyone that says, ‘Oh, we know that this is perfectly safe,’ I say is either unbelievably stupid, or deliberately lying. The reality is, we don’t know. The experiments simply haven’t been done, and now we have become the guinea pigs.”  ~ David Suzuki, geneticistNow that the mainstream media is catching on to the public sentiment against GMO food, or at least against unlabeled GMO food, to the tune o [...]

7 Reasons You Need More Magnesium

Margie King, GuestMagnesium is the fourth most abundant mineral in your body.  But few people fully appreciate this miraculous mineral. The human genome project reveals that 3,751 human proteins have binding sites for magnesium.[i]  And so far we know this one essential mineral activates over 350 biochemical processes in the body to keep things flowing.Here are just seven good reasons to get more magnesium today. 1.

For the first time, scientists find complex organic molecules in an infant star system

ALMA has detected the complex organic molecule methyl cyanide in the outer reaches of the disk in the region where comets are believed to form. This is another indication that complex organic chemistry, and potentially the conditions necessary for life, is universal. (B. Saxton/NRAO/AUI/NSF)



Excerpt from washingtonpost.com

We're not special. Or our complex organic molecules aren't, anyway. And that's good news in the hunt for extraterrestrial life.

In a new study published Wednesday in Nature, astronomers found the first signs of the complex, carbon-based molecules that make life possible on Earth in a protoplanetary disk; the region where cosmic building blocks gather to create planets in a brand-new star system. The cyanides found there are essential to life as we know it: without them, there would be no proteins.

"We know when our own solar system was very young, it was rich in water and complex organics. We know that from observing comets," explained study author Karin Öberg, an assistant professor of astronomy at Harvard. Comets have kept the molecules of our solar system's early days locked up tight ever since, which is why scientists are so eager to study them for clues about Earth's formation. These comets show us that certain organic molecules were common in our solar system's pre-planetary days.

But this is the first time we've seen evidence of such molecules ready to seed another star system with planets that could support life.
"We're finding that we're not that special," Öberg said. "Other young solar systems in the making are also rich in the same volatiles, and in similar proportions."

And in this case, she said, being not-special is a great thing: If other solar systems formed just the way ours did, we can hope that they formed some kind of life, too.

Öberg and her colleagues found the molecules using the Atacama Large Millimeter/submillimeter Array (ALMA), a radio telescope with some pretty sweet resolution. They spotted the complex organics as much as 15 billion kilometers from the star itself, which they believe is right smack dab in the middle of the system's comet-forming region. That means the organics could get locked away in comets, just as the ones in our solar system were, and go out to seed future planets with them (as some believe was the case with Earth).

"It was kind of a chance discovery, because we weren't targeting this specific molecule," Öberg said. So she and her team need to go back and look more systematically. She also hopes they'll be able to find more systems to look at. The star they've observed -- MWC 480, located some 455 light-years away in the Taurus star-forming region -- is twice the mass of the sun, so they also hope to find some that are more similar to our host star.

 "We of course want to know whether this is a really common thing or if we just lucked out on this one," Öberg said.

Surprising discovery finds proteins can be assembled without genetic instructions ~ Sends scientists back to drawing board





Excerpt from news.bioscholar.com


A study has shown for the first time that the building blocks of proteins can be assembled without instructions from DNA or messenger RNA (mRNA).

A protein, Rqc2, was found playing a role similar to that of mRNA and specifying which amino acids, the building blocks of proteins, to be added in cell mechanism.

“In this case, we have a protein playing a role normally filled by mRNA,” said Adam Frost, assistant professor at University of California, San Francisco.

“This surprising discovery reflects how incomplete our understanding of biology is,” said first author Peter Shen, a postdoctoral fellow in biochemistry at the University of Utah in the US.

The researchers added that the findings have implications for new therapies to treat neurodegenerative diseases such as Alzheimer’s, Amyotrophic lateral sclerosis (ALS) or Huntington’s.

The researchers described that ribosomes are machines on a protein assembly line, linking together amino acids in an order specified by the genetic code.

When something goes wrong, the ribosome is generally disassembled, the blueprint is discarded and the partly made protein is recycled.

The new study, however, revealed that before the incomplete protein is recycled, Rqc2 can prompt the ribosomes to add just two amino acids (of a total of 20) – alanine and threonine – over and over, and in any order.

The nonsensical sequence likely serves specific purposes. The code could signal that the partial protein must be destroyed, or it could be part of a test to see whether the ribosome is working properly, the researchers noted.

For the study, they fine-tuned a technique called cryo-electron microscopy to flash freeze, and then visualse, the quality control machinery in cells in action.

The findings appeared in the journal Science.

Hemp Repairs Damaged DNA

by hightimes.comScientists have discovered astounding new evidence that suggests hemp proteins have the capacity to repair damaged DNA -- a phenomenon that occurs in all humans as the result of aging. While the majority of people are aware that DNA, or deoxyribonucleic acid, is present within most living organisms, there is perhaps a larger percentage who are completely oblivious to the fact that this hereditary material accumulates damage in a manner similar to wear and tea [...]

Scientists Admit There Is a Second, Secret DNA Code Which Controls Genes

Contributed by Michael ForresterThe fascinating and recent discovery of a new, second DNA code 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 [...]
