Want To Stay Healthy? You’ll Need To Become A Human-Animal Hybrid

Posted by in categories: biotech/medical, health

No thanks.


Biologists have been mixing the DNA of different animals since the 1970s, but the idea of injecting the genes of animals into humans remains taboo. Called transgenics, it’s a practice that could cure illness in the future — and eventually reshape our species. Here’s what you need to know about it.

Using Adenosine Triphosphate to Create Biological Super-Computers

Posted by in categories: biotech/medical, computing, engineering, nanotechnology, sustainability

Machines running on human energy? Yes, it can happen, according to Dan Nicolau, Jr. from the Department of Integrative Biology at the University of California. Nicolau and his colleagues successfully completed a proof-of-concept study of a book-sized computer that runs on adenosine triphosphate (ATP), a biochemical that releases energy in cells and aids in energy transfer.

The study results published in the Proceedings of the National Academy of Sciences (PNAS), describe the combination of geometrical modeling and engineering as well as nanotechnology to create circuitry that uses 1.5 × 1.5 cm in area and the naturally occurring protein to operate.

Air pollution can mess up your brain

Posted by in categories: biotech/medical, health, life extension, neuroscience

I am not surprised at all by this finding given the other issues with pollution such as cancer from carcinogens, asthma, sinus infections, etc.


Air pollution is a known culprit in lung and heart disease. Fine particulate matter, tiny particles, 1/30th the width of a human hair, are released into the air by power plants, factories, cars and trucks. These fine particles somehow invade the body’s defenses and do the most damage. Air quality is worst in urban areas with increased traffic. New research points out that air pollution negatively affects brain and cognitive development in young children and teenagers.

Moreover, Jennifer Weuve, an assistant professor of internal medicine at Rush Medical College, found that older women who had been exposed to high levels of the pollution experienced greater cognitive decline compared with other women their age (Archives of Internal Medicine, 2012). Other studies cite black carbon in the form of soot as a cause of cognitive decline in an aging population for both men and women. Simply put: Dirty air messes up the brain.

Drug candidate shrinks tumor when delivered by plant virus nanoparticle

Posted by in category: biotech/medical

Nice.


In a pair of firsts, researchers at Case Western Reserve University and Massachusetts Institute of Technology have shown that the drug candidate phenanthriplatin can be more effective than an approved drug in vivo, and that a plant-virus-based carrier successfully delivers a drug in vivo.

Triple-negative breast cancer tumors of mice treated with the phenanthriplatin –carrying nanoparticles were four times smaller than those treated either with cisplatin, a common and related chemotherapy drug, or free phenanthriplatin injected intravenously into circulation.

An optical window for deep brain imaging

Posted by in categories: biotech/medical, neuroscience

Very nice; researchers have now discovered a method for viewing deep brain imaging through using NIR light at wavelengths of 1600–1870nm Very big deal especially for patients with things like Giloblastoma Multiforme (GBM), and other neuro disorders and diseases.

I remember when my two aunts suffered from GBM, and many doctors could not get iimaging view in some areas of my aunts brains which would have been beneficial in understanding how ingrain the GBM was in their brain cells. So, hopefully this finding will help others in getting better answers to diseases like GBM and in turn better treatment as well developed.


Near-IR light at wavelengths of 1600–1870nm offers the best transmittance for deep brain imaging.

The Elderly May One Day Swap Their Motorized Scooters for Robotic Suits

Posted by in categories: biotech/medical, cyborgs, robotics/AI, wearables

Robotic exoskeletons, long a staple of sci-fi novels, comic books, and movies, are now part of the real world—and they’ve mostly followed the sci-fi model. That is, exoskeletons are wearable robots. All metal, all the time. But metal suits are heavy and power hungry, and the human body isn’t metal. If you actually plan to use an exoskeleton for an extended period of time, this can be a bit of a design flaw.

That’s where a new exosuit developed by SRI International is looking to flip the script. Instead of working to build exoskeletons—which are rigid like their namesake—SRI is using soft robotics to make lightweight, wearable “exomuscles” and “exotendons.”

Instead of a human-shaped heavy metal frame, SRI’s exosuit is soft, pliable, and intelligent. The suit learns and adapts to its wearer’s movements to give them a boost when needed. It’s quick to put on and relatively energy efficient.

The Wrestler

Posted by in category: biotech/medical

I have fond memories of both of my grandfathers as a boy growing up in the American Southwest. My mother’s father was a master gardener, able to grow plants in an arid environment that should have thrived only in tropical rainforests. Botanists from the Department of Biology at the local university surveyed his garden, and promptly asked him to help with problems they were experiencing in their greenhouses. There were large fruit trees scattered throughout his backyard perfect for climbing and eating apples, peaches, or cherries fresh off the branch. The foliage of these trees was dense, making it possible to hide and pounce down on unsuspecting younger brothers or cousins wandering too near the danger zone. Not saying I ever did such a thing, just saying it was possible. You know?

Every Friday night we ate dinner at my mother’s parents’ house. I poignantly remember an after dinner ritual. My grandfather would retire to his recliner, toothpick in his mouth, and instruct one of his grandchildren to turn on the bulky multicomponent console color television with built in radio, turntable, and speakers. It was time to watch Friday night boxing. There was no remote control, we kids were the channel changers and volume knob manipulators. My grandfather was usually not an emotional man, but he would become quite animated and occasionally agitated watching the fight, particularly if there was a boxer he favored in the match. The grandchildren enjoyed watching him more than we did the pugilists on the flickering television screen.

My father’s father, on the other hand, was a wrestling fan. By wrestling, I mean the wrestling seen on Saturday afternoon television featuring men in tight shorts, outlandish costumes, some wearing hoods or masks over their heads, entering the ring wearing colorful capes to either wild applause or catcalls and hisses, bouncing off the ropes to clothesline their onrushing opponent, and jumping from the turnbuckles to land on their hapless opponent laid out on the mat below. Even to a boy it was obvious bad theater and fraud, but I enjoyed watching my grandfather yelling at the television, berating the bad guys and the referees during these spectacles. He knew the name of every hero and villain, and he would hurl epitaphs at the masked men in tight wrestling suites while openly cheering for those he admired. He particularly loved the chaos of tag team matches, guaranteed to degenerate into a free-for-all with all the combatants in the ring, throwing chairs, and occasionally even body slamming the referee to the canvas. I still remember some of the names and can mentally visualize the antics; Gene Kiniski, The Sheik, Ray Mendoza, Dory Funk Jr., Terry Funk, Mad Dog Vachon, Hard Boiled Haggarty, Raul Reyes, Killer Kowalski, and Johnny Valentine. As I grew older I mistakenly pointed out these matches were all rehearsed and the outcomes were scripted; this wasn’t real sport. He fixed me with a glare, informed me I was getting, “a little too big for my britches”, and asked me if I thought 250 lb. men climbing to the top of the ropes to hurl themselves on their foe below, or the prostrate , seemingly stunned wrestler on the mat absorbing the flying blow delivered from above should be considered as anything less than athletic.

Good point. I wouldn’t want to do it.

What will we do when money has no meaning? And if everyone gets life extension what will today’s mega rich think and/or do about it?


May you live in interesting times – A curse, origin unknown

One of the ‘curses’ usually attributed to ancient China, but frequently thrown around in today’s society is ‘May you live in interesting times’, suggesting that living in turbulent times, no matter the cause, is somehow a bad thing.
