Robots exchange ‘genetic material’ in mating experiment to evolve

Posted by in categories: genetics, robotics/AI

Researchers from Vassar College expanded on efforts in evolutionary robots to include developmental factors for the first time. Robots were able to ‘reproduce’ to spur 10 generations.

Genetically Modified Cells Just Cured Two Babies of Leukemia

Posted by in categories: biotech/medical, genetics

  • In 2016 alone, 58,320 people in the U.S. died from leukemia. This new development could increase a patients’ chance of survival
  • Current treatment methods can increase a patient’s risk of secondary cancer after remission. This Engineered T-Cell approach has not shown to be carcinogenic

Wouldn’t it be wonderful if the need for chemotherapy no longer existed? In some cases, these treatments aren’t even effective enough to send patients into remission, but for many people, there are few other options.

What if there was an easier and more effective way to tackle cancer? Thanks to one recent case, there is.

Customized babies are closer than you think

The race is on to edit genes and prevent disease. But this technology is ripe for abuse.

Economic inequity already exists in the reproductive industry. IVF, for example, is not covered by insurance in most states (Massachusetts excepted), setting up a situation in which only infertile people with well-padded pockets can afford the treatment. And of course the well-off have easier access to good health care via quality private insurance — or their own bank accounts. Steve Jobs, for example, spent $100,000 in 2011 to sequence his genome and that of his pancreatic tumor — a bill not many could hope to afford.

“The beautiful thing about this [gene-editing] work is it offers an opportunity to intervene around the moment of birth,” says Katy Kozhimannil, an associate professor in the Division of Health Policy at University of Minnesota’s School of Public Health. “That said, as we pay attention to the opportunity of that moment, it’s important to bear in mind the value of liberty and justice for all.”

Random mutations play large role in cancer, study finds

Posted by in categories: biotech/medical, genetics, life extension

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- iTunes

Posted by in category: genetics

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.

10 AMAZING Abilities HIDDEN in Your GENES

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.

Scientists find a low-cost way to build genomes from scratch

Posted by in categories: biotech/medical, computing, genetics

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.

Scientists just changed the way we build genomes to make them 270,000 times cheaper

Posted by in categories: biotech/medical, genetics, health

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.

Researchers find a way to reverse antibiotic resistance in Mycobacterium tuberculosis

Posted by in categories: biotech/medical, genetics

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.

The terrifying DNA discoveries that are making science-fiction fact

Posted by in categories: biotech/medical, genetics, transhumanism

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.

For more, look to the new book “The Gene Machine: How Genetic Technologies Are Changing the Way We Have Kids — and the Kids We Have” by Bonnie Rochman.
