Robot Invasion?

With the drastic increase of technology in robotics in the past decade, should we be fearful robots will take our jobs in the future?

Robot apocalypse anyone?

Posdoctoral research fellow Brian Gleeson in the University of British Columbia computer science department doesn’t believe so – his paper “Gestures for Industry” seeks to push the boundaries of human interactions with robots in a society where mass production is essential for satisfying the demand for goods by consumers.

Significant technological advancements in relatively short periods of time have not only resulted in better household goods, but have also extended to the production process itself. The use of robots in every nook and cranny of industrial assembly lines has allowed for faster, more efficient production of goods. However, over the years, the transition to more mechanized labour has come under fire from the human workforce – many fear for the security of their jobs.

This video below shows the progress of technology and robotics, and what this implies for job security:

Technological advancements are showing no signs of slowing down, so are robots destined to take over the production process entirely?

Fortunately not, and many will take comfort in learning that the “Gestures for Industry” paper explores the integration of robotic assistants to increase efficiency, safety and to reduce stress on workers.

Dr. Gleeson has extensively studied human-human interactions, as well as human-robot interactions using only hand gestures to accomplish various tasks. Through this, they discovered that participants, human or robot, must know what the task is ahead of time. For example, knowing whether the task is placing a part in a specific location or manipulating multiple parts is imperative to fully understanding their partner’s hand gestures. Just like the human-human teams, the human-robot teams were able to perform these tasks that communicated specific details without any vocal, touch or eye communication. Dr. Gleeson’s research is one of the first stepping-stones towards human-robot interactions and the future implications of these findings are endless.

While the field of robotics is undoubtedly advancing at a significant rate, human workers need not be concerned with being out of a job. Dr. Gleeson states that robots have already replaced humans in the workforce wherever possible, and that the next step to a safer, more efficient production process requires humans and robots to coexist and cooperate with each other, ultimately resulting in a higher standard of living.

On a side-note, a recent article from Forbes reports robots will actually create more jobs.

Burn Fat in 8 Seconds

After a long winter it’s no doubt that we all put on a few extra pounds. Summer is on the horizon and you know you’ll have to shed your winter wear, exposing those soft spots around your belly and love handles.

Unfortunately, the average student usually has too much on their plate from commuting to school to late night cramming sessions. This leaves no time for long intensive workouts at the gym.

What if we can get more out of our workouts with less time and less effort?

Too good to be true?

Well a team of scientists out of Australia might have solved this problem for all us “busy” people. Dr. Boutcher and his team placed 45 overweight women through their SPRINT-training which is a short, high-intensity training based on cycle sprints over 12 weeks. They discovered a significant drop in their abdominal fat and an increase in muscle mass.

Nothing out of the ordinary, high-intensity training has been known to be a great fat burning workout, but this is where it gets very interesting.

It was found  1 hour  SPRINT-training a week burns the same amount of body fat in men as jogging for 7 hours a week.

So what is SPRINT training?

Using a fitness bike, you sprint for 8 seconds, followed by 12 seconds of exercising lightly for a total of 20 minutes. You would perform this 20 minute exercise three times a week for a total of 1 hour of exercise a week, which should fit in anybody’s schedule.

Why does it work?

“We think the reason that it works is because it produces a unique metabolic response,” said Professor Boutcher.

During the intermittent 8 second sprinting large amounts of catecholamine is released. A specific hormone that is involved in oxidizing fat storage which results in greater weight loss.

Furthermore, with this short burst of high intensity output with a longer period if normal output hinders the build up of lactic acid in your muscles. This is that painful burn you feel when your muscles are actually doing work, in simple terms this type of training helps prolong your workouts because it takes longer for your muscle to tire out.

This video gives a brief overview of where catecholamine and other steroids come from:

This kind of exercise is great for people who don’t have time to spend hours in the gym, and even better you only require a stationary bike which is not that expensive to purchase for yourself.

Lastly, Dr. Boutcher notes that “Overall, any type of exercise is good. You just have to work out your objectives, whether it is to increase muscle, lose fat, or enhance other aspects of your life such as improving the quality of your sleep.”

Let’s Get Ready to Rumble!

Whenever Michael Buffers announces “Let’s get ready to rumble!” I get a tingly feeling at the back of my neck because I know what’s about to go down, two men who have trained for months are about to go to battle in a ring with only some gloves on. Being a boxing fan nothing is more entertaining than seeing a boxer knocking out (KO) his opponent.

But I never thought of the implications the boxers face, until I saw the debilitating state of one of the greatest boxers ever to live, Muhammad Ali. At the age of 42, in 1984 Ali was diagnosed with Parkinson’s disease, doctors and scientists believe that the main culprit for the disease was possibly the repeated blows to the head he received during his reign in the ring.

Finding studies on this matter was not too difficult, it seems in the recent years it has been a field of intensive study.

“A knock-out in neuro-psychiatric terms corresponds to a cerebral concussion.”

In 2010, a study out of the Technical University of Munich conducted by Hans Forstl evaluated the health of boxers for the past 10 years. They discovered that getting knocked out resulted in persistent symptoms such as headaches, impaired hearing, nausea, unstable gait, and forgetfulness. A long career in boxing may result in boxer’s dementia (dementia pugilistica), which is strikingly similar to Alzheimer’s disease.

So what exactly happens to cause a knock-out?

A report by Popular Mechanics written by Marita Vera goes into technical aspect of the knock-out.

The body contains dissolved sodium, potassium and calcium, collectively known as electrolytes, which are responsible for conducting impulses along neurons. Every time a fighter receives a blow to a nerve, potassium leaves the cell and calcium rushes in, destabilizing the electrolyte balance, while the brain does all it can to keep these levels in balance. With each successive blow, this balance becomes harder and harder to maintain, and more and more energy must be spent in the process. When the body reaches the point where the damage outweighs the body’s ability to repair itself, the brain shuts down, to conserve enough energy to fix the injured neurons at a later point.”

Dr. Charles Bernick and his colleges from the Cleveland Clinic’s Lou Ruvo Center for Brain Health have compiled over a 100 boxers and mixed martial artists (MMA) fighters to conduct studies on their brain. Through M.R.I scans, they found a reduction in the size in the hippocampus and thalamus of the brains of fighter with more than six years in the ring. Dr. Bernick notes that “these parts of the brain deals with the function of memory and alertness.”

Prevention?

Along with Dr. Bernick’s work, Sanna Neselius and her team out of Gothenburg, Sweden are working on bio-markers in the blood that indicates the severity of damage to ones brain.

“Preferably, we would like to find a simple blood test that provides the same information as our more advanced brain fluid examinations. The capability does not presently exist, but can perhaps become an option in the future with further and more extensive studies.”

Discovering what these boxers have put on the line, day in and day out has gained a great sense of respect from my part, hopefully through the power of science there will be better ways to prevent and protect these courageous men and women doing their jobs, while not taking anything away from the true essence of boxing.
