Coating technique helps bionic implants fit right in

By Darren Quick

18:12 July 5, 2009 PDT

Six million dollars probably wouldn’t get you much of a bionic man these days, but a new process for coating metal implants could vastly improve the lives of the growing number of people who have undergone complicated total joint replacement surgeries. The new electrochemical process improves the implants’ functionality, longevity and integration into the body by producing a coating that is virtually indistinguishable from the body’s own material.

What’s on your mind – microelectrodes offer poke free brain control

By Darren Quick

18:01 July 3, 2009 PDT

The brain is one of our most delicate organs. It’s not really meant to be prodded and poked, hence the nice protective skull surrounding it. That fragility makes experimental devices that use tiny electrodes poking into the brain to help paralyzed people use computers and potentially let amputees control bionic limbs, a risky proposition. But now a new University of Utah study shows that brain signals controlling arm movements can be detected accurately using new microelectrodes that sit on the brain, but don't penetrate it.

Robotic jaws give dentists something to chew on

By Darren Quick

17:49 July 2, 2009 PDT

In news that might be a little worrying when coupled with our recent story of the flesh-eating robotic clock, UK researchers have developed a Chewing Robot. Thankfully the uses for the Chewing Robot are more benign - it has been developed to study the wear and tear on dental elements, such as fillings, crowns and bridges. By reproducing the motion and forces sustained by teeth within a human mouth, the robot has the potential to dramatically improve the process of developing and testing new dental materials.

Toyota makes a wheelchair steered by brain waves

By Peter Puya Abolfathi

17:35 July 2, 2009 PDT

Toyota and Japanese research foundation RIKEN have teamed up to create a revolutionary wheelchair steered by mind control. This remarkable development is one of the first practical uses of EEG (Electro-encephalogram) signals. Designed for people with severe disabilities, the Toyota/RIKEN wheelchair is fitted with an EEG detector in the form of a electrode array skull cap, a cheek puff detector and a display that assists with control. To turn left, right and move forward, the driver simply thinks about the movement and the wheelchair instantly and seamlessly responds. To stop the wheelchair, the driver puffs his/her cheek. A detector on the face picks up the signal and immediately stops the wheelchair. This form of braking is necessary for safety reasons as a puff detector is more reliable than the EEG reader.

Over 60% of all U.S. bankruptcies attributable to medical problems

By Mike Hanlon

14:02 June 6, 2009 PDT

June 6, 2009 An article in the latest issue of The American Journal of Medicine makes chilling reading, and presents compelling evidence that the US health care system is broken. In 2007, before the current economic downturn even began, an American family filed for bankruptcy in the aftermath of illness every 90 seconds; three-quarters of them were insured. Over 60% of all bankruptcies in the United States in 2007 were driven by medical incidents. Summarising the results of the first-ever national U.S. random-sample survey of bankruptcy filers, the article shows the share of bankruptcies attributable to medical problems rose by 50% between 2001 and 2007. Medical bankruptcy is a unique American phenomenon, which does not occur in countries that have national health insurance. Read More

Invasive Alien Species threatening global biodiversity

By Mike Hanlon

15:34 May 24, 2009 PDT

While the implications of climate change for biodiversity have been widely recognised, the insidious effect of invasive alien species (IAS) on global biodiversity stays under the radar. Last Friday was the United Nations’ International Day for Biological Diversity (IDB) and the International Convention on Biological Diversity sees IAS as “one of the greatest threats to biodiversity, and to the ecological and economic well-being of society and the planet”. “Increasing globalisation has led to greater movement of new species around the world, and native species killed or stressed by global change will all too often be replaced by these weeds and feral animals,” says CSIRO Biodiversity Research Director, Dr Mark Lonsdale.

Inherited outlook – can our feelings effect our children?

By Mike Hanlon

02:56 May 18, 2009 PDT

Now here's a frightening thought! Brain chemicals such as endorphins, and drugs, such as marijuana and heroin are known to have significant effects on sperm and eggs, altering the patterns of genes that are active in them. In an article published in the latest issue of the journal Bioscience Hypotheses, Dr Alberto Halabe Bucay of Research Center Halabe and Darwich, Mexico, suggested that the hormones and chemicals resulting from happiness, depression and other mental states can affect our eggs and sperm, resulting in lasting changes in our children at the time of their conception. Bucay suggests that a wide range of chemicals that our brain generates when we are in different moods could affect ‘germ cells’ (eggs and sperm), the cells that ultimately produce the next generation. Such natural chemicals could affect the way that specific genes are expressed in the germ cells, and hence how a child develops. Read More

Radical tissue scaffold to treat knee injuries

By Darren Quick

23:21 May 16, 2009 PDT

Damage to knee cartilage is one of the more common types of sports injuries. Treatment often involves drilling a hole through the cartilage into the bone to stimulate the bone marrow to release stem cells, transplanting cartilage and the underlying bone from another part of the joint, or removing cartilage cells from the body, stimulating them to grow in the lab and re-implanting them. Now MIT engineers have built a new tissue scaffold that can stimulate bone and cartilage growth when transplanted into knees and other joints, potentially offering a more effective, less expensive – and painful – option to more conventional therapies.

Surgery may not be necessary for Achilles tendon rupture

By Mike Hanlon

23:37 May 14, 2009 PDT

May 15, 2009 The Achilles tendon, which attaches the calf muscle to the heel, is the body's strongest tendon. The tendon may rupture on sudden tensing of the muscle, something that affects middle-aged men in particular, typically when playing badminton or tennis. The two ends of a ruptured Achilles tendon are often stitched together before the leg is put in plaster, in order to reduce the risk of the tendon rupturing again. However, a thesis from the Sahlgrenska Academy, University of Gothenburg, Sweden, now suggests that surgery may be unnecessary. Patients who do not undergo surgery have just as good a chance of recovery. Read More

At last – a functional and elegant Hospital Gown

By Mike Hanlon

21:57 May 14, 2009 PDT

History has fortunately overlooked the designer of the humble and seemingly universal hospital gown. Just as well, really, because he/she was no doubt well meaning and probably not due the universal curses that they have been subject to. Regardless, after more than a century, it's one of those semi-dysfunctional inventions that has endured because the chronically underfunded health systems of the world have always had more urgent technologies on their agenda than replacing the hated and embarassing garb. If you're like most people, you've probably spent waaaay too much time with your nether regions protruding from one of those dreadful hospital gowns. Now the University of Cincinnati is employing its design research capabilities to design better gown options which will soon be on display and may even reach market. Read More

The world’s largest ambulance (and the world’s smallest X-ray unit)

By Mike Hanlon

02:08 May 14, 2009 PDT

"Scalpel please! " is a sentence that might in future not only be heard in a hospital operating theatre, but also in one of the three new, large-capacity Mercedes-Benz ambulances handed over to the Centre of Ambulance Services of the Government of Dubai. From now on, it is the hospital that comes to the patient in Dubai. The clinic buses were ordered so that rapid medical assistance can be rendered in the event of major emergencies with large numbers of injury victims. As is well-known, the survival chances of very seriously injured persons in large measure depend on rapid first treatment, and this is the purpose of the large-capacity ambulances. Read More

New EEG method predicts neurological recovery of cardiac arrest patients
