3D Printing the Way to Bionic Humans

A pressure sensor printed directly on a hand is a step toward new biomedical devices, “on the fly” wearable technology, and more…

(Inside Science) — Wearable technology may soon be at your fingertips — literally. Researchers have developed a pressure sensor that can be 3D printed directly on your hand. The device, sensitive enough to feel a beating pulse, is made from soft, stretchy silicone that conforms to the curves of your fingertip.

It’s a step toward a more seamless integration of human and machine, said Michael McAlpine, a materials scientist at the University of Minnesota in Minneapolis. His team didn’t print the device on a real hand yet — just an artificial one. “But,” he said, “it sets the stage for future work in 3D printing electronic devices directly on the body.”

Someday, that could mean technology evocative of the cyborgs and bionic humans of science fiction. In the nearer term, 3D printed gadgets on and in the body could aid medical treatment, health monitoring and surgery.

This AI Company Offers Cryogenic Freezing With Its Health Plan

Staff members who die will be put in cold storage until medical science can revive them.

Since congressional Republicans voted in a bill containing the Trump administration’s roll back of the Affordable Care Act, healthcare is once again a topic on everyone’s lips. In the absence of any universal healthcare scheme, employer-provided medical coverage is a crucial benefit for employees, tempting people to stay at jobs they might otherwise have left, or apply for positions they wouldn’t otherwise consider.

In the contest to attract new hires, tech companies often supplement already generous salaries with comprehensive benefit packages, and in this vein one company has hit on a novel idea: A health plan that covers its employees beyond death and into the realms of a speculative future rebirth.

‘Straight out of the Nazi playbook’: Hindu nationalists try to engineer ‘genius’ babies in India

“Members of a Hindu far-right organization called Arogya Bharati say they are working with expectant couples in the country to produce “customized” babies, who, they hope, will be taller, fairer and smarter than other babies, according to a report in the Indian Express newspaper.”

“The group’s health officials claimed that their program — a combination of diet, ayurvedic medicine and other practices — has led to 450 of these babies, and they hope to have “thousands” more by 2020, the report said.”

“The parents may have lower IQ, with a poor educational background, but their baby can be extremely bright. If the proper procedure is followed, babies of dark-skinned parents with lesser height can have fair complexion and grow taller,” Hitesh Jani, the group’s national convener, told the newspaper.”

Confirmed: AI Can Predict Heart Attacks and Strokes More Accurately Than Doctors

University of Nottingham researchers created an AI system that scanned routine medical data to predict which patients would have strokes or heart attacks within 10 years. The AI system beat the standard method of prediction, correctly making calls in 355 more cases than traditional means. Predicting cardiovascular events like strokes and heart attacks is a notoriously challenging task. In fact, the researchers note in their recent paper that around half of all strokes and heart attacks occur in patients who were never identified as being “at risk.”

The records included a decade of health outcomes, lab data, drug information, hospital records, and demographic information. The team identified the distinguishing characteristics of patients who experienced strokes and heart attacks using 75 percent of the records. They then tested their models against the standard guidelines using the remaining 25 percent of the records. The standard guidelines scored 0.728 out of 1.0, with the latter signifying 100 percent accuracy. The machine models scored between 0.745 to 0.764, with the neural network making 355 more accurate predictions than the standard guidelines, therefore earning the best score. Had those predictions been made in real time, the patients could have been provided with preventative care.

“Exercise in a Pill” Boosts Athletic Endurance

Summary: Chemical compound mimics the beneficial effects of exercise, including fat burning and increasing stamina, a new study reports.

Sedentary mice given the drug ran longer without training.

Every week, there seems to be another story about the health benefits of running. That’s great—but what if you can’t run? For the elderly, obese or otherwise mobility-limited, the rewards of aerobic exercise have long been out of reach.

Eating bogies is good for teeth and overall health, scientists conclude

Vomit.

It might be wise to look away now if you are eating or have a weak stomach, but scientists have discovered that ingesting bogies is good for teeth, and overall health.

Scientists at a number of universities including Harvard and Massachusetts Institute of Technology (MIT) say parents should not discourage their children from picking their noses because they contain ‘a rich reservoir of good bacteria.’

Eating snot can also prevent bacteria from sticking to teeth, according to the article published in the journal of the American Society for Microbiology.

When energy drinks contained real (radioactive) energy

Nothing like a deep, penetrating, pervasive case of radiation poising to give you the energy you need to keep you awake, focused, alert and energetic all day long. lol.

But there was a time when energy drinks actually contained real energy. The active ingredient in these drinks was radium, a radioactive element that releases a packet of radiant energy with every atomic decay. While the connection between consuming a radioactive element and reaping a perceived energy boost is tenuous at best, it didn’t stop people in the early 1900s from ignoring the known downsides of ingesting radioactivity and risking the long-term health consequences.

“Exercise-in-a-pill” boosts athletic endurance

The push to find exercise memetics continues.

Every week, there seems to be another story about the health benefits of running. That’s great—but what if you can’t run? For the elderly, obese or otherwise mobility-limited, the rewards of aerobic exercise have long been out of reach.

Salk Institute scientists, building on earlier work that identified a gene pathway triggered by running, have discovered how to fully activate that pathway in sedentary mice with a chemical compound, mimicking the beneficial effects of exercise, including increased fat burning and stamina.

Parkinson’s linked to gut bacteria

For the first time, researchers have found a functional link between the bacteria in the gut and the onset of Parkinson’s disease, one of the world’s most common debilitating brain disorders.

A team of scientists from several institutions in the United States and Europe showed how changing the bacteria in the guts of mice affected the manifestation of Parkinson’s symptoms — even including bacteria taken from the guts of humans with the disease.

The findings suggest a new way of treating the disease: The best target for treatment may be the gut, rather than the brain. The researchers hope the new information can be used to develop “next generation” probiotics, more sophisticated than the sort of probiotics found on the shelves of health food stores today.

An artificial womb successfully grew baby sheep — and humans could be next

Inside what look like oversized ziplock bags strewn with tubes of blood and fluid, eight fetal lambs continued to develop — much like they would have inside their mothers. Over four weeks, their lungs and brains grew, they sprouted wool, opened their eyes, wriggled around, and learned to swallow, according to a new study that takes the first step toward an artificial womb. One day, this device could help to bring premature human babies to term outside the uterus — but right now, it has only been tested on sheep.

It’s appealing to imagine a world where artificial wombs grow babies, eliminating the health risk of pregnancy. But it’s important not to get ahead of the data, says Alan Flake, fetal surgeon at the Children’s Hospital of Philadelphia and lead author of today’s study. “It’s complete science fiction to think that you can take an embryo and get it through the early developmental process and put it on our machine without the mother being the critical element there,” he says.

Instead, the point of developing an external womb — which his team calls the Biobag — is to give infants born months too early a more natural, uterus-like environment to continue developing in, Flake says.
