IBM Research looks into ninja polymers

IBM might have a world champion in the form of a chess computer a fair number of years ago, but intellectual pursuits are not the only agenda on the computing giant’s radar. They have taken an interest in the world of biology this time around, where IBM Research is looking into a new method of killing bacteria such as the deadly methicillin-resistant Staphylococcus aureus (MRSA), although this one will not result in the use of antibiotics, but will be based on semiconductor technology instead. This particular group of scientists were previously looking for a way to perform microscopic etching on silicon wafers at a far smaller scale compared to what is available in the market at the moment, but during the course of their research, they managed to identify materials which are able to produce an electrostatic charge when chained to form a polymer.

iBrain will let us know what’s on Stephen Hawking’s mind

Stephen HawkingLast year, the folks over at NeuroVigil came up with a device called the iBrain – a brain scanner that can collect data from a person’s brain. The iBrain was attached to Stephen Hawking who was then told to visualize making a fist with his right hand. Whatever went through his brain at that moment was then collected by the iBrain. As to what the data is, we don’t know now but it looks like we’ll be able to find out very soon.

Dr. Philip Low of NeuroVigil recently announced to The Star, “We will present the data we were able to generate from Stephen Hawking.” The data will be revealed this Saturday, July 7th, at the Francis Crick Memorial Conference. If you’re interested in finding out the details, head over to fcmconference.org this Saturday where the event will be streamed live.

Researchers create ‘rubber-band electronics’ material, capable of stretching up to 200 percent (video)

Researchers create 'rubberband electronics' capable of stretching

One of the major issues with embedded medical devices is the lack of flexibility in existing electronics. Fortunately, researchers at the McCormick School of Engineering at Northwestern University have developed a new material that can create electronic components capable of stretching to 200 percent of their original size. One of the major obstacles was how stretchable electronics with solid metal parts suffered substantial drops in conductivity but this solution involves a pliable three-dimensional structure made from polymers with ‘pores’. These are then filled with liquid metal which can adjust to substantial size and shape changes, all while maintaining strong conductivity. We’ve embedded a very brief video of the new stretchable material going up against existing solutions — it’s right after the break.

Life vest comes in handy during cardiac arrest

Wait a minute here, you say. How the heck can a life vest actually come in handy when one suffers from a cardiac arrest? Well, the answer is pretty simple actually – the person wearing it is not drowning away in a pool of water, but his or her heart has stopped beating temporarily. You as the caregiver will need to deliver rapid cooling to the patient before any brain damage occurs after a cardiac arrest, which is where this life vest comes in handy. Thanks to the efforts of researchers at Hohenstein Institute in Boennigheim, Germany, this particular vest, when put on immediately, will be able to deliver rapid cooling to a patient.

The system makes such rapid cooling a possibility, as it does so via a zeolite cartridge which will release its contents into the volume of water located within the vest itself, cooling it via absorption into the patient. Perhaps this particular life vest might one day make its way to an AED packs, who knows? Even those without any medical knowledge will then be able to administer the right amount of care.

Smoking Vaccine Could Block Nicotine Buzz

After working in a hospital for over a decade, I’ve been around many people that had major health problems related to smoking. Combine the health issues with the fact that smoking is just absolutely disgusting to me, I think everyone should stop smoking. Especially my UPS driver, who routinely delivers me packages that smell like a used ashtray.

My dad used to smoke so I can appreciate how hard it is for people to quit, though. Scientists have been working on a vaccine that is designed to flood the body with an antibody to attack nicotine as it enters the body, rendering it useless as a source of pleasure.

smoker

The researchers are conducting a study in mice and have found that the so-called smoking vaccine is up to 85% effective at blocking nicotine in a mouse brain. The researchers say years of additional research is needed before the vaccine can be tested on people.

“As far as we can see, the best way to treat chronic nicotine addiction from smoking is to have these Pac-Man-like antibodies on patrol, clearing the blood as needed before nicotine can have any biological effect.” The challenge according to the researchers has been to develop a vaccine that is able to produce enough antibodies to stop nicotine from entering the brain and delivering the effects smokers crave.

New system lets you type with your brain using MRIs

New system lets you type with your brain using MRIs

This isn’t mind reading, per say. Instead Bettina Sorger, Joel Reithler, Brigitte Dahmen and Rainer Goebel at Universiteit Maastricht have figured out a way to monitor the flow of blood in the brain and associate the images captured using an MRI with the letters of the alphabet. The whole system takes about an hour to learn and configure for each individual. Trials focused on healthy individuals, but clearly its the paralyzed and people suffering from diseases like ALS that have the most to gain. Sorger hopes to enable “locked-in” patients to finally be able to communicate with the outside world by thinking out letter at a time. Obviously, patients aren’t going to be able to install an MRI in their homes, much less lug one around with them. The data collected could be used to finely tailor less accurate but more portable systems for patients that monitor electrical or light signals. If you’re interested in the real nitty-gritty you can check out the complete research paper at the source link.

Brain scanner assists paralyzed person to spell words

Some paralyzed folk feel as though they are trapped in a “prison”, having failed to use their motor functions before their paralysis, and this can be quite a challenging and disheartening place to be in. However, there is hope in the form of a new brain scanner which was specially developed in order to help those who are completely paralyzed, by allowing them to “speak” using just the power of their thoughts. This is made possible thanks to the implementation of functional magnetic resonance imaging (fMRI) that will enable patients to select between 27 characters – the alphabet and of course, a blank space. I guess future versions would include punctuations and numbers, too.

This unique brain scanner can pick up the finer nuances, as each character results in a different pattern of blood flow in the brain, hence enabling the device to interpret such patterns. The British Neurological Association claimed the research as “exciting”, and I quite agree with them. It would certainly help one bridge communication with a fully paralyzed person, and who knows – one of the world’s greatest novels might eventually be “written” by thought alone down the road.

Oxygen-infused microparticles could keep patients alive without breathing

Researchers at Boston Children’s Hospital were able to design tiny, gas-filled microparticles that can be injected directly into the bloodstream to oxygenate blood. These microparticles are reportedly made up of a single layer of lipids or fatty molecules that surround a tiny pocket of oxygen gas and are immersed in a liquid solution. According to Dr. John Kheir of the Department of Cardiology at Boston Children’s Hospital, when these microparticles were infused into animals that have low blood oxygen levels, the blood oxygen saturated to almost normal in a matter of seconds. Other tests revealed that when the microparticles were infused into animals with blocked trachea or windpipe, it reportedly kept the animals alive for 15 minutes without breathing.

Other results showed that the microparticles reduced the occurrence of cardiac arrest and organ injury to the animals. Dr. Kheir explains that the microparticles will most likely be administered only for 15 and 30 minutes because it can overload the blood if used longer. He also noted that the particles are different from blood substitutes, and that it is designed for cases where in a person’s lung is rendered incapacitated. Researchers are hoping that the microparticle will be used someday in emergency situations where in paramedics will need more time to safely place a breathing tube or perform other life-saving therapies on patients.

Smart t-shirt helps monitor ill patients

You know the saying, if you can’t get the mountain to come to you, you would have to go to the mountain instead. Well, I guess the same can be said of doctors, although most folks would prefer to head to the hills than visit the doctor. This particular smart t-shirt comes embedded with its fair share of sensors that allows it to monitor patients suffering from Chronic obstructive pulmonary disease (COPD) and Chronic kidney disease (CKD) remotely. Of course, the flexibility of such an invention allows the smart t-shirt to be adapted, catering for folks living with other incurable chronic illnesses that require long term care. (more…)

Detecting Parkinson’s could be as easy as placing a simple phone call

Parkinson’s is a degenerative disorder that targets the central nervous system, causing tremors, shaking, stiff muscles and otherwise limited mobility. Unfortunately there is no cure, nor can it be detected via blood tests. However it can be detected via our voices, which is why TED fellow and mathematician Max Little has developed an algorithm that will help detect Parkinson’s in a person simply by making a phone call. The phone call will listen to the caller’s voice and will run it through the algorithm. However in order to make the algorithm more accurate and have a wider database in which they can compare it with, Little is currently seeking help by asking volunteers to place a simple phone call. In the meantime you can check out the video above for more information on Little’s project, or you can also pop on over to his website for the details and to see what else he is working on.
