Doctors Replaced a Soldier’s Lost Ear Using a Wild Medical Technique

Posted by in categories: biotech/medical, materials

In a first for United States Army doctors, Burrage received an ear transplant that was grown from her own tissue inside her own body. A team, led by Lieutenant Colonel Owen Johnson III, the chief of plastic and reconstructive surgery at William Beaumont Army Medical Center in El Paso, Texas, harvested cartilage from Burrage’s ribs, carved it into the shape of an ear, and implanted it under the skin in her arm. There, it developed blood vessels, which Johnson says will allow Burrage to regain feeling in the ear once it’s healed. In an announcement released on Monday, Johnson called the operation a success.

Self-navigating AI learns to take shortcuts: study

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

A computer programme modelled on the human brain learnt to navigate a virtual maze and take shortcuts, outperforming a flesh-and-blood expert, its developers said Wednesday.

While artificial intelligence (AI) programmes have recently made great strides in imitating human brain processing—everything from recognising objects to playing complicated board games—spatial navigation has remained a challenge.

The first smallpox treatment is one step closer to FDA approval

Posted by in categories: biotech/medical, terrorism

Upcoming anti-viral medication for smallpox…


As bioterrorism fears grow, the first treatment for smallpox is nearing approval.

Called tecovirimat, the drug stops the variola virus, which causes smallpox, from sending out copies of itself and infecting other cells. “If the virus gets ahead of your immune system, you get sick,” says Dennis Hruby, the chief scientific officer of pharmaceutical company SIGA Technologies, which took part in developing the drug. “If you can slow the virus down, your immune system will get ahead.”

New Wearable Oral Sodium Sensor to Help Fight Hypertension

Posted by in categories: biotech/medical, wearables

Researchers from the Georgia Institute of Technology have built a flexible, wearable oral sodium sensor that could help monitor a person’s sodium intake.


A leading cause of hypertension is a person’s uncontrolled salt intake. This often results in high blood pressure and heart complications.

As a solution, the Georgia Institute of Technology researchers built the oral sodium sensor that could be easily worn in the mouth to monitor salt intake.

Future anti-aging drugs could flip a “metabolic switch” to mimic fasting

Posted by in categories: biotech/medical, life extension

Fasting has been found to have a range of health benefits, and appears to slow down the aging process. Now, researchers from MIT have found that fasting for just 24 hours is enough to improve the regeneration of a person’s intestinal stem cells, which naturally declines with age. Better yet, with the metabolic switch identified, in the future the effect could be mimicked with a drug.

As with stem cells in all parts of the body, intestinal stem cells are in charge of growing new cells in the organ. They maintain the lining of the intestine, which is shed and replaced every few days, fight off infection and repair damage to the tissue. But as is usually the case, these stem cells get less and less effective at their job with age.

Previous research has found that caloric restriction, or continual fasting, has a profound effect on health and longevity. These effects have been seen in mice, rats, monkeys, lemurs, and other animals, and although human studies haven’t really been conducted, it seems that we could also benefit from harnessing the diet. So the MIT team set out to study the effects of fasting on intestinal stem cells.

Baldness cure could come from side-effect of cancer drug

Posted by in categories: biotech/medical, genetics

A cure for baldness could be on the horizon after British scientists discovered that an osteoporosis drug stimulates hair growth three times quicker than other drugs.

Around four in 10 men suffer male pattern baldness by the age of 45 and two thirds by the age of 60.

At the moment only two drugs, minoxidil and finasteride, are available for the treatment of male pattern baldness (androgenetic alopecia) — the classic type of receding hair loss in men.

Life Extension Technology in Science Fiction

Posted by in categories: biotech/medical, life extension, robotics/AI

Today we take an amusing look at how science fiction is often portrayed in a jarring way especially when dealing with the topic of life extension.

Those of us who fancy science fiction stories are used to all sorts of technological miracles taking place in them; some are plausible and might become reality at some point in the future, while others are mere fantasies, artistic liberties that are taken to tell a better story and will likely never translate into real-life technologies—or, if they will, they will do so at the cost of rethinking fundamental principles that we’ve thus far considered to be fully established.

In science fiction, we’ve seen faster-than-light travel, teleportation, portals, energy weapons, strong AI, telepathic powers, and radiation-induced superpowers of all kinds; unfortunately, the only “superpower” known to be actually induced by radiation thus far is cancer. Entire imaginary worlds have revolved around the existence of one or more of these marvels, and series and shows have assumed that they’re possible and imagined what our society would be like with them, but one particular possibility has been neglected or relegated to one or two episodes and then forgotten, as if it was of no importance whatsoever: the defeat of aging.

Dr. Sarah Constantin – The Longevity Research Institute

Posted by in categories: biotech/medical, life extension

Today, we have an interview with the Longevity Research Institute, a new group set to launch in April 2018 of this year. The goal of the Institute is to identify therapies that can demonstrably extend healthy human lifespan by 2030 at the latest.

Searching for longevity

There are dozens of compounds and therapies that have been demonstrated to increase the lifespan of mammals. Recently, there have been some impressive examples of rejuvenation in animals using a variety of approaches, including partial cellular reprogramming, stem cell therapy, and senescent cell removal. More importantly, in many of these studies, age-related diseases have been delayed or even reversed.

The Fourth Industrial Revolution is Here!

Posted by in categories: biotech/medical, economics, education, employment, government, information science, law, mathematics, robotics/AI

So much talk about AI and robots taking our jobs. Well, guess what, it’s already happening and the rate of change will only increase. I estimate that about 5% of jobs have been automated — both blue collar manufacturing jobs, as well as, this time, low-level white collar jobs — think back office, paralegals, etc. There’s a thing called RPA, or Robot Process Automation, which is hollowing out back office jobs at an alarming rate, using rules based algorithms and expert systems. This will rapidly change with the introduction of deep learning algorithms into these “robot automation” systems, making them intelligent, capable of making intuitive decisions and therefore replacing more highly skilled and creative jobs. So if we’re on an exponential curve, and we’ve managed to automate around 5% of jobs in the past six years, say, and the doubling is every two years, that means by 2030, almost all jobs will be automated. Remember, the exponential math means 1, 2, 4, 8, 16, 32, 64, 100%, with the doubling every two years.

We are definitely going to need a basic income to prevent people (doctors, lawyers, drivers, teachers, scientists, manufacturers, craftsmen) from going homeless once their jobs are automated away. This will need to be worked out at the government level — the sooner the better, because exponentials have a habit of creeping up on people and then surprising society with the intensity and rapidity of the disruptive change they bring. I’m confident that humanity can and will rise to the challenges ahead, and it is well to remember that economics is driven by technology, not the other way around. Education, as usual, is definitely the key to meeting these challenges head on and in a fully informed way. My only concern is when governments will actually start taking this situation seriously enough to start taking bold action. There certainly is no time like the present.
