The tardigrade genome has been sequenced, and it has the most foreign DNA of any animal

Posted by in categories: biotech/medical, food, life extension, space

Scientists have sequenced the entire genome of the tardigrade, AKA the water bear, for the first time. And it turns out that this weird little creature has the most foreign genes of any animal studied so far – or to put it another way, roughly one-sixth of the tardigrade’s genome was stolen from other species. We have to admit, we’re kinda not surprised.

A little background here for those who aren’t familiar with the strangeness that is the tardigrade – the microscopic water creature grows to just over 1 mm on average, and is the only animal that can survive in the harsh environment of space. It can also withstand temperatures from just above absolute zero to well above the boiling point of water, can cope with ridiculous amounts of pressure and radiation, and can live for more than 10 years without food or water. Basically, it’s nearly impossible to kill, and now scientists have shown that its DNA is just as bizarre as it is.

So what’s foreign DNA and why does it matter that tardigrades have so much of it? The term refers to genes that have come from another organism via a process known as horizontal gene transfer, as opposed to being passed down through traditional reproduction.

Ray Kurzweil: https://en.wikipedia.org/wiki/Ray_Kurzweil#Health_and_aging

Raymond “Ray” Kurzweil is an American author, computer scientist, inventor and futurist. Aside from futurology, he is involved in fields such as optical character recognition (OCR), text-to-speech synthesis, speech recognition technology, and electronic keyboard instruments. He has written books on health, artificial intelligence (AI), transhumanism, the technological singularity, and futurism. Kurzweil is a public advocate for the futurist and transhumanist movements, and gives public talks to share his optimistic outlook on life extension technologies and the future of nanotechnology, robotics, and biotechnology.

This device enables doctors to reanimate the hearts of the dead

Posted by in category: biotech/medical

Yeah that’s right, this is indeed a beating human heart in a box. It just seems to look a lot like Frankenstein, but this is probably one of the big revolutions that can definitely increase the amount of heart donors.

The system consists of a sterile chamber in which the heart is kept safe, oxygen supply and a couple of tubes that can be used to deliver blood and nutrients. This device is giving doctors the ability to use hearts that first couldn’t be used.

At first only heart beating donors could donate their hearts, so this boils down to the fact that only brain-dead donors we’re able to donate theirs. This is due to the fact that after your death the condition of your organs begins to decrease. Therefore it can be pretty dangerous to ‘install’ a new heart in a living patient.

Circuit Board Tattoos That Actually Work Will Bring Your Cyborg Fantasies To Life

Posted by in categories: biotech/medical, cyborgs

There’s a common misconception that tattoos are only a way to express your individuality (just like everyone else does), or only serve as loving tributes to moms. But they have practical medical applications too, especially now that circuit board temporary tattoos exist.

Developed by Chaotic Moon Studios, which describes itself as a “creative technology studio,” these Tech Tats use conductive inks (in lieu of actual tattoo inks) that only sit on the surface of the skin so they’re not permanent. After all, given the speed at which technology evolves, the last thing you want is a permanent circuit board tattoo on your arm that’s outdated within a year.

China to build world’s biggest animal cloning factory in Tianjin

Posted by in categories: biotech/medical, business

Tianjin is building the world’s largest animal cloning factory, aiming to produce one million cattle embryos annually, state media reported yesterday.

According to a Xinhua, mainland scientists have signed a deal to establish a 200 million yuan (HK$242 million) commercial animal cloning centre in the Tianjin Economic-Technological Development Area, a government-sponsored business development park.

Its main building was already under construction and due to be completed by June next year, the report said. Among the animals it will clone are sniffer and pet dogs, high-grade beef cattle, racehorses and “non-human primates”. These animals will be used for commercial services and improving breeds.

Hacking the Brain — Restoring Lost Abilities With the Latest Neurotechnologies

Posted by in categories: biotech/medical, computing, cyborgs, genetics, nanotechnology, neuroscience, Ray Kurzweil

A few weeks ago, I wrote about Ray Kurzweil’s wild prediction that in the 2030s, nanobots will connect our brains to the cloud, merging biology with the digital world.

Let’s talk about what’s happening today.

Over the past few decades, billions of dollars have been poured into three areas of research: neuroprosthetics, brain-computer interfaces and optogenetics.

Aubrey de Grey: Can We and Should We Give Ourselves Indefinite Youth? Oh Yes

Posted by in categories: biotech/medical, life extension

The marginalization of anti-aging research is our most shameful humanitarian failure.

Aging is a hot topic among the chattering classes these days. What with biotech companies like Calico and Human Longevity Inc. being founded with the mission to defeat aging, and venerable institutions such as Prudential proclaiming the imminence of superlongevity on billboards, there’s no denying that this is a time of great interest in our oldest and deepest-held dream — to escape from the tyranny of inexorable and ultimately fatal physiological decline.

But hang on — is the buzz around aging really reflective of what’s being done to realize this goal? The briefest dispassionate analysis reveals a different story altogether. The proportion of government spending allocated in the industrialized world to diseases and disabilities of old age is appropriately high, but it is overwhelmingly dedicated to the transparently quixotic approach of attacking those ailments directly — as if they were infections — rather than attacking their lifelong accumulating causes.

Why South Korea is the plastic surgery capital of the world

Posted by in category: biotech/medical

Seoul, South Korea, is the global plastic surgery capital.

The high-status neighborhood of Gangnam reportedly has 500 aesthetic centers alone.

Why the concentration? Because South Korea has the most plastic surgeries per capita on earth, with over 980,000 recorded operations in 2014. That’s 20 procedures per 1,000 people, putting it ahead of the US’s 13 procedures per 1,000. And Korea has had the most operations per capita since 2009.

Electric fields remove nanoparticles from blood with ease

Posted by in categories: biotech/medical, engineering

Engineers at the University of California, San Diego developed a new technology that uses an oscillating electric field to easily and quickly isolate drug-delivery nanoparticles from blood. The technology could serve as a general tool to separate and recover nanoparticles from other complex fluids for medical, environmental, and industrial applications.

Nanoparticles, which are generally one thousand times smaller than the width of a human hair, are difficult to separate from plasma, the liquid component of blood, due to their small size and low density. Traditional methods to remove from typically involve diluting the plasma, adding a high concentration sugar solution to the plasma and spinning it in a centrifuge, or attaching a targeting agent to the surface of the nanoparticles. These methods either alter the normal behavior of the nanoparticles or cannot be applied to some of the most common nanoparticle types.

“This is the first example of isolating a wide range of nanoparticles out of plasma with a minimum amount of manipulation,” said Stuart Ibsen, a postdoctoral fellow in the Department of NanoEngineering at UC San Diego and first author of the study published October in the journal Small. “We’ve designed a very versatile technique that can be used to recover nanoparticles in a lot of different processes.”
