First prosthesis in the world with direct connection to bone, nerves and muscles

Posted by in categories: biotech/medical, cyborgs

Thanks to the electrodes system a stable signal is obtained, which allows precise control like handling an egg without breaking. It also provides sensations as if it were a real hand.

The first prosthesis in the world that connects directly to the bone, nerves and muscles, allows the person to experience sensations, free mobility and is handled using the mind.

It was created by the Mexican Max Ortiz Catalan, who lives in Sweden, the device becomes an extension of the human body through osseointegration, this means that it connects directly to the bone via a titanium implant, and thanks to the neuronal and muscle binding interfaces a robust and intuitive control of the artificial hand is achieved, this way just by thinking about it is possible to move the limb.

HIV Genes Successfully Edited Out of Immune Cells

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

This could have some truly profound implications for the treatment of all viruses, including HIV!


Researchers from Temple University have used the CRISPR/Cas9 gene editing tool to clear out the entire HIV-1 genome from a patient’s infected immune cells. It’s a remarkable achievement that could have profound implications for the treatment of AIDS and other retroviruses.

When we think about CRISPR/Cas9 we tend to think of it as a tool to eliminate heritable genetic diseases, or as a way to introduce new genes altogether. But as this new research shows, it also holds great promise as a means to eliminate viruses that have planted their nefarious genetic codes within host cells. This latest achievement now appears in Nature Scientific Reports.

Resurrection and Biotechnology

“He is not here; He has risen,” — Matthew 28:6

As billions of Christians around the world are getting ready to celebrate the Easter festival and holiday, we take pause to appreciate the awe inspiring phenomena of resurrection.

In religious and mythological contexts, in both Western and Eastern societies, well known and less common names appear, such as Attis, Dionysus, Ganesha, Krishna, Lemminkainen, Odin, Osiris, Persephone, Quetzalcoatl, and Tammuz, all of whom were reborn again in the spark of the divine.

DNA from Mysterious ‘Denisovans’ Helped Modern Humans Survive

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

Genetic mutations from extinct human relatives called the Denisovans might have influenced modern human immune systems, as well as fat and blood sugar levels, researchers say.

Very little is known about the Denisovans. The first evidence of them was discovered in Denisova Cave in Siberia in 2008, and DNA from their fossils suggests they shared an origin with Neanderthals but were nearly as genetically distinct from Neanderthals as Neanderthals were from modern humans.

Previous work found that any modern humans with ancestry outside of Africa inherited about 1.5 to 2.1 percent of their DNA from Neanderthals. In contrast, prior research suggested that substantial levels of Denisovan ancestry are found only in the Pacific islands of Melanesia. Scientists are increasingly uncovering the effects of Neanderthal ancestry on modern humans, from potential immune boosts to increased risks for depression, obesity, heart attacks, nicotine addiction. However, relatively little was known about the effects of Denisovan ancestry.

Treating disease at stage zero

Posted by in categories: bioengineering, biotech/medical, health, information science, nanotechnology

It sounds really obvious, but hospitals aren’t for healthy people. The world’s entire health system is really there to react once people get ill. If doctors are able to catch an illness at stage one that’s great, but if it reaches stage three or four there’s often not that much that can be done. So what if we could treat patients at stage zero and predict the likelihood of contracting diseases? We could then get treatment to people who need it much earlier and take preventative steps to avoid illness altogether.

Currently, when we think of monitoring in healthcare we’re usually referring to monitoring patients’ reactions to drugs or treatments, but this is changing. No amateur runner’s uniform is complete these days without a Fitbit or some kind of analytics tool to monitor progress, so the idea of monitoring the healthy is becoming ingrained in the public’s consciousness. But Fitbits only scrape the surface of what we can do. What if the data from fitness trackers could be combined with medical records, census data and the details of supermarket loyalty cards to predict the likelihood of contracting a particular disease?

With big data we can move from reacting to predicting, but how do we move beyond just making predictions; how do we prevent disease from occurring altogether? Up until now all of our monitoring technology has been located outside of the body, but nano-sized entities made of DNA could one day patrol the body, only acting when they come into contact with specific cells – cancer cells, for example. The technology that would turn tiny machines – roughly the size of a virus – into molecular delivery trucks that transport medication is already being worked on by bioengineers. If this kind of technology can be used to treat cancer, without needing to release toxic agents into the body, can the same technology be inserted into a healthy person and lie in wait for the opportunity to fight disease on its host’s behalf?

DARPA using peripheral nerve stimulation to accelerate learning

Posted by in categories: biotech/medical, cyborgs, neuroscience

The body’s branching network of peripheral nerves connects neurons in the brain and spinal cord to organs, skin, and muscles, regulating a host of biological functions from digestion to sensation to locomotion. But the peripheral nervous system can do even more than that, which is why DARPA already has research programs underway to harness it for a number of functions—as a substitute for drugs to treat diseases and accelerate healing, for example, as well as to control advanced prosthetic limbs and restore tactile sensation to their users.

Now, pushing those limits further, DARPA aims to enlist the body’s peripheral nerves to achieve something that has long been considered the brain’s domain alone: facilitating learning. The effort will turn on its head the usual notion that the brain tells the peripheral nervous system what to do.

The new program, Targeted Neuroplasticity Training (TNT), seeks to advance the pace and effectiveness of a specific kind of learning—cognitive skills training—through the precise activation of peripheral nerves that can in turn promote and strengthen neuronal connections in the brain. TNT will pursue development of a platform technology to enhance learning of a wide range of cognitive skills, with a goal of reducing the cost and duration of the Defense Department’s extensive training regimen, while improving outcomes. If successful, TNT could accelerate learning and reduce the time needed to train foreign language specialists, intelligence analysts, cryptographers, and others.

Research devises a way to track RNA in living cells through CRISPR-Cas9

Posted by in categories: biotech/medical, genetics

On track to resolving defective RNA through CRISPR-Cas9.


According to a study published in journal Cell on March 17, researchers at University of California, San Diego School of Medicine, have found a way to track RNA in living cells. CRISPR-Cas9, a DNA-editing technique will be applied to target RNA in order to find cure for presently untreatable diseases such as cancer and autism.

There are many diseases that are associated with RNA behavior, which carries the genetic code from the cell’s nucleus. There was no technique found until now that could track RNA in living cells efficiently. However now, CRISPR-Cas9, which so far was only able to manipulate DNA, would now target RNA, which is also called RNA-targeted Cas9.
