Genomic instability (mutations) has been suggested as being one of the primary hallmarks of aging and this research might support that idea. Researchers at John Hopkins report that around 66% of mutations in cancer cells are due to random errors with environment/lifestyle contributing 29% and 5% inherited.

“That finding challenges the common wisdom that cancer is the product of heredity and the environment. “There’s a third cause and this cause of mutations is a major cause,” says cancer geneticist Bert Vogelstein.”

“Such random mutations build up over time and help explain why cancer strikes older people more often. Knowing that the enemy will strike from within even when people protect themselves against external threats indicates that early cancer detection and treatment deserve greater attention than they have previously gotten, Vogelstein says.”

RUPTURE follows Renee Morgan (Noomi Rapace), a single mom, who is deathly terrified of spiders. While in route to meet up with a friend, she is violently abducted by a group of strangers. After enduring intense yet strange questioning and examinations, some about her fear of spiders, Renee soon discovers that she is now the subject of an underground experiment. Her captors explain to her that she has a genetic abnormality that can potentially allow her to “rupture” and reveal her alien nature. Renee must find a way to escape before it is too late.

Amazing Genes are HIDDEN inside of us; Science has found it. In 2014 one of the craziest science experiments by some incredible scientists at Oxford University found that less than 10% of human DNA is active, meaning that the majority of your genetic code is just sitting around doing nothing.

If you’ve ever been in a fight with a child, and I know I have, you’ll soon realise that their bodies have an uncanny ability to heal faster than an adult’s. Every human on Earth possesses a gene called ACTN3, but for some people this gene possesses a very special ability — the ability to be totally badass at sports. When my head is in a bouquet of flowers or I’m hovering over a batch of freshly baked cookies, I wonder how great this must smell to a dog. Remember that movie where Bruce Willis had unbreakable bones and Samuel L Jackson played a weird guy who said he was unbreakable and he proved it when he was in a car crash and his bones were unbreakable?The ability to hibernate for months at a time is a trait man has envied ever since the invention of the Lay-Z-Boy. Instead of sleeping for months, how awesome would it be to need no more than four hours sleep and still feel as refreshed as you would after sleeping in till noon? Remember the mice from the regeneration gene entry? Ever wanted to swim underwater without having to worry about that pesky little thing called drowning? On the surface this ability may sound pretty neat, because imagine how good chocolate or steak would be if your sense of taste was ramped up a few notches? The ability to become infected by an ancient virus may not seem like the best dormant trait to wake up, but they can’t all be winners now can they?

To put it mildly, sequencing and building a genome from scratch isn’t cheap. It’s sometimes affordable for human genomes, but it’s often prohibitively expensive (hundreds of thousands of dollars) whenever you’re charting new territory — say, a specific person or an unfamiliar species. A chromosome can have hundreds of millions of genetic base pairs, after all. Scientists may have a way to make it affordable across the board, however. They’ve developed a new method, 3D genome assembly, that can sequence and build genomes from the ground up for less than $10,000.

Where earlier approaches saw researchers using computers to stick small pieces of genetic code together, the new technique takes advantages of folding maps (which show how a 6.5ft long genome can cram into a cell’s nucleus) to quickly build out a sequence. As you only need short reads of DNA to make this happen, the cost is much lower. You also don’t need to know much about your sample organism going in.

As an example of what’s possible, the team completely assembled the three chromosomes for the Aedes aegypti mosquito for the first time. More complex organisms would require more work, of course, but the dramatically lower cost makes that more practical than ever. Provided the approach finds widespread use, it could be incredibly valuable for both biology and medicine.

In 2003, the US Department of Defense and the National Institutes of Health announced that—13 years and $2.7 billion later—they had finally finished mapping the human genome.

But the quest to understand human genetics was far from over: Genomes, which are the entire layout of our 3 billion base pairs of DNA, vary dramatically from person to person. So mapping the first human genome was really just mapping a human genome (the patient’s identity was kept secret for privacy.) And even though shorter genetic sequencing is available, doctors studying rare genetic diseases need the full scope of a patient’s genetic material to find the problematic mutation. Finding these faulty sections of genes is like a microscopic version of Where’s Waldo among 3 billion people wearing stripes, a game that has cost $3 billion to play.

In a paper published (paywall) in Science on March 23, researchers from the Baylor College of Medicine, Massachusetts Institute of Technology, and Harvard University said they have figured a way to sequence the entirety of any genome for just $10,000, in a couple of weeks. Their test project? Re-sequencing the DNA of the mosquito species that spreads the Zika virus.

A team of researchers from Sweden, France, Belgium and Switzerland has found a way to reverse resistance to an antibiotic drug used to treat tuberculosis. In their paper published in the journal Science, the team describes how they screened compounds that activated different pathways to activate ethionaide, a compound used to treat tuberculosis.

The researchers are currently working with GlaxoSmithKline and Biotech Bioversys to further develop the small prototype molecule into a drug that can be mass produced and sold.

(Medical Xpress)—A team of researchers from Sweden, France, Belgium and Switzerland has found a way to reverse resistance to an antibiotic drug used to treat tuberculosis. In their paper published in the journal Science, the team describes how they screened compounds that activated different pathways to activate ethionaide, a compound used to treat tuberculosis.

The development of antibiotics to treat bacterial infections has very clearly made the world a healthier place. Unfortunately, over time, bacteria have been evolving to thwart such compounds, putting us all at risk once again. Because of that, scientists have been searching for new treatments, or in some cases, ways to make old treatments work again using new techniques. In this new effort, the researchers have found a way to make ethionaide, a prodrug (a compound that is metabolized in the body to produce a desired drug), become effective again in patients infected with of Mycobacterium tuberculosis.

Imagine a world where parents can give birth to superbabies with bones so strong they’re impervious to a surgical drill and a heart less prone to failure. A world where a child has DNA from three parents, not two. A world where it’s possible for a woman to have her favorite movie star’s child simply by collecting a few of his skin cells. Genetic technology is making it all a reality, horrifying some and heartening others.

Reproductive advances are arriving so rapidly, we’ve already entered the realm of science-fiction and are on the verge of making truly astounding leaps.

Science has taken another step toward delivering the perfect newborn – or at least a bouncing baby free of certain genetic defects.

Chinese researchers used a genome editing technique called CRISPR to rid normal embryos of hereditary diseases that cause blood disorders and other ailments, according to New Scientist. Experts who reviewed the project told the publication that, even though it involved just six embryos, it carries promise.

“It is encouraging,” Robin Lovell-Badge, a human genome expert at the Francis Crick Institute in London, told New Scientist.

This is nowhere near the power of the biggest systems, but still allows us to participate in research and development powered by supercomputer.

The idea that a computer could deliver an increase in life expectancy arises for a number of reasons, Prof Desplat says. Major gains are expected from the emergence of personalised medicine, care specifically tailored to match your genetic make-up. This will be driven in the not too distant future by “deep artificial intelligence learning” run on a supercomputer. These will also deliver faster more accurate early diagnosis, he says.

These computers are used in a variety of ways, from weather forecasting and climate modelling to energy usage modelling, statistical processing and seismic analysis when prospecting for oil and gas.

George Church is very interested in your memories now.

Harvard researcher George Church is looking for people with exceptionally good memory to take part in a study aimed at finding genetic mechanisms that boost memory in research that could one day result in better drugs or diagnostic tests.

Church and other researchers at Harvard’s Wyss Institute for Biologically Inspired Engineering and Harvard Medical School’s Personal Genome Project, in collaboration with Lumos Labs — the makers of the brain-training game Lumosity — will look for common genetic markers in individuals with exceptional memories, attention and reaction speeds.
