Roundup of Medical Technology: Robots in surgery, diagnosis and active aging companion, 'body on a chip' and heart tissue from a spinach leaf

Robot-assisted surgery is reaching an incredible level of precision!

Watch the video at the link and see for yourself how it peels a grape and then sews it back on!  It's astounding.

Robot Worm could be miniaturized to help doctors spot digestive issues

The robot that can move forwards or backwards in a wave-like motion is known as the single actuator wave-like robot (SAW) and was developed by researchers at Ben-Gurion University of the Negev (BGU) in Israel.

Artificial Intelligence Will Help the Elderly  Watch the video at the link to see how ElliQ works

For the past month or so, a small group of older adults in San Francisco has been learning to engage with a talking device named ElliQ. It’s more desk lamp than archetypal robot—think of the hopping light at the beginning of Pixar movies. But while ElliQ is meant to sit on a table or nightstand, it’s all about movement, or more accurately, body language.

ElliQ talks. But it also moves, leaning toward the person with whom it’s speaking. It lights up, too, as another means of engagement, and uses volume and sound effects to distinguish its messages. “If ElliQ is shy, she will look down and talk softly, and her lights will be soft,” explains Dor Skuler, CEO and founder of Intuition Robotics, the Israeli company behind the device. “If she tries to get you to go for a walk, she will lean forward and take a more aggressive tone, and her lights will be bright....

ElliQ keeps learning...One of the first steps in establishing a relationship with this particular robot is to set some goals, such as how many times a week a person wants to go out for a walk or be reminded to see friends. Then, it’s up to ElliQ to determine the most effective way to do its job. In other words, it will learn that one person responds better to “It’s nice out, why don’t you go for a walk,” while another needs to be prodded more aggressively with “You’ve been on the couch watching TV for four hours. Time to get up and take a walk.”  “That’s where the emotive side kicks in,” he says. “ElliQ can set a whole different tone, and use different body language and gestures based on what works and what doesn’t work. The machine fine-tunes itself.”

“Mass-Produced” Blood Now Possible,

Researchers at the University of Bristol and NHS Blood and Transplant....developed a method to freeze stem cells in their early development — while they are still replicating — which has the effect of “immortalizing” them such that scientists can produce infinitely more stem cells. They will harvest the excess stem cells to produce blood.  Right now the new method is cost-prohibitive. For the foreseeable future, it will mostly be used to provide hard-to-source blood for patients with rare blood types.

Spinach Leaf Transformed Into Beating Human Heart Tissue

Using the plant like scaffolding, scientists built a mini version of a working heart, which may one day aid in tissue regeneration.

Menstrual cycle recreated 'in a dish'

US scientists say they have made a mini working replica of the female reproductive tract using human and mouse tissue...to construct a palm-sized device that ooks nothing like a womb, fallopian tubes and ovaries.  Researchers say it should help with understanding diseases of these organs and tissues and a novel way  to test new treatments.

The work is part of a project to create the entire human "body on a chip". The ultimate goal would be to take cells from any given individual in order to create a personalized model of their body to test drugs and treatments on.

We Were Wrong - the Testes Are Connected to the Immune System

Some parts of the body – including the tissues of the brain and testes – have long been considered to be completely hidden from our immune system....Last year scientists made the amazing discovery that a set of previously unseen channels connected the brain to our immune system; now, it appears we might also need to rethink the immune system's relationship with the testes...potentially explaining why some men are infertile and how some cancer vaccines fail to provide immunity.

An Unexpected New Lung Function Has Been Found - They Make Blood!  Video at the link shows how

In experiments involving mice, the team found that they produce more than 10 million platelets (tiny blood cells) per hour, equating to the majority of platelets in the animals' circulation. This goes against the decades-long assumption that bone marrow produces all of our blood components.

Researchers from the University of California, San Francisco also discovered a previously unknown pool of blood stem cells that makes this happen inside the lung tissue - cells that were incorrectly assumed to mainly reside in bone marrow....Scientists have now watched megakaryocytes functioning from within the lung tissue to produce not a few, but most of the body's platelets. So how did we miss such a crucial biological process this whole time?  The discovery was made possible by a new type of technology based on two-photon intravital imaging - a similar technique to one used by a separate team this week to discover a previously unidentified function of the brain's cerebellum.

UPDATE:  Paralyzed man moves his arm and hand with the power of his mind and a microchip

A cycling accident left Bill Kochevar unable to move from the shoulders down, but  he can now feed himself in his wheelchair, using a microchip in his brain. He is the first quadriplegic to have his movement restored by the system...
‘For somebody who’s been injured eight years and couldn’t move, being able to move just that little bit is awesome’...Researcher Dr Bob Kirsch said: ‘He’s really breaking ground for the spinal cord injury community. This is a major step toward restoring some independence.’
