According to UPI.com, scientists may be coming closer to producing environmentally friendly, magnetic refrigerators. Imperial College London researchers say magnetic refrigeration technology could provide a "green" alternative to traditional gas-compression refrigerators, requiring up to 30 percent less energy without the use of ozone-depleting chemicals or producing greenhouse gases.
"This is an exciting discovery because it means we may one day be able to tailor-make a material from the 'bottom up' … so it ticks all the boxes required to run a magnetic fridge," said Professor Lesley Cohen, one of the researchers. "This is vitally important because finding a low-energy alternative to the fridges in our homes and work places is crucial for cutting our carbon emissions and tackling climate change."
A magnetic refrigeration system works by applying a magnetic field to a magnetic material, causing it to heat. That heat is removed from the system by water, cooling the material back to its original temperature. When the magnetic field is removed the material cools even further, and it is that cooling property that researchers hope to harness for a wide variety of applications.
The research, led by James Moore, is reported in journal Advanced Materials. Readers should keep their eyes out for future developments of this unique and ground-breaking technology.

Doctors in Pittsburgh, Pennsylvania are experimenting with a new procedure that just might spare us a lifetime of heartburn problems.
Dr. James Luketich, a surgeon at the UPMC in Pittsburgh, recently admitted a 24 year-old acid reflux patient into a clinical trial that utilizes a sort of magnetic bracelet for treatment.
In a typical acid reflux case, the valve that is supposed to close after meals will malfunction and therefore remain open, allowing acid to leak. This can cause an uncomfortable feeling in the chest that we know as heartburn.
The key component in the aforementioned procedure is a device called the LINX Reflux Management System, which is surgically inserted into the patient. Once inside, the LINX's magnets create a tension that prevents acid reflux.
Casey Donahoe, the patient who participated in Luketich's trial, has reported positive results, but according to Luketich, it's too early to say whether this is the definite answer to these problems. However, he does agree that the early results warrant further trials.

According to a recent press release, Charles K. Herman, M.D., F.A.C.S., Medical Director of Plastic and Reconstructive Surgery at Pocono Health System recently co-authored one of the first comprehensive review articles that describes the use of magnetic fields in healing. The article was published in this month’s Aesthetic Surgery Journal, the official journal of the American Society of Aesthetic Plastic Surgeons.
The article is titled “Evidence-Based Use of Pulsed Electromagnetic Field Therapy in Clinical Plastic Surgery.” Dr. Berish Strauch, Emeritus Chair of Plastic Surgery at Albert Einstein College of Medicine, Dr. Arthur Pilla from Columbia University, Nobel Laureate Dr. Louis Ignarro, and Dr. Richard Dabb of John Hopkins University joined Dr. Herman in authoring this article. Dr. Herman is one of the first physicians to implement the technology available for electromagnetic field therapy and began using it at Pocono Medical Center three years ago to assist in healing difficult chronic wounds.
To author the article, Dr. Herman and the contributing physicians assessed the major scientific breakthroughs and current understanding of PEMF therapy. Through their research, they found that PEMF therapy has been used successfully in the management of postsurgical pain and edema and in the treatment of various chronic wounds.

Butler Hospital in Providence, RI is looking to boost its fundraising efforts in order to back a new brain study initiative that could help those suffering from mental illness. The hospital, which is a national leader in mental health treatments, is looking to begin more extensive research in many areas of mental health treatment, including depression, Alzheimer’s Disease, and other memory disorders using vagus nerve stimulation.
Just recently, the hospital made its excellence in mental health research clear by introducing a new treatment that could revolutionize the way patients with depression are treated. This ground breaking approach is called Transcranial Magnetic Stimulation. It uses an electronic device that beams magnetic pulses through the skull to trigger small electrical changes. This is just a small fraction of what Butler is capable of. With added funds and the support of the community, Butler may be able to introduce revolutionary treatments that could change the way we look at medicine.
“It will enable us to recruit first rank researchers or to support young researchers who will grow someday into developing new treatments and new understanding of how the brain actually works,“ said Pat Recupero, President of Butler Hospital, in an interview with local media channels.

I received my first order today, just when you said it would arrive!
The quality of the ring and bracelet are excellent. I'm sure I will be ordering more items.

Stop and think about this for a minute - The oceans magnetic fields not only exist but can be seen. Wow - take a moment to learn more about magnetic fields and the world you live in and on.
Captured from space: weak magnetic fields generated by the motion of the oceans (Pic: Science)
The first global snapshot of the weak magnetic fields generated by the movement of salty water in the Earth's oceans has been obtained, creating a potentially powerful new tool for understanding climate.
The research by ocean physicist Dr Robert Tyler of the University of Washington and colleagues at Germany’s Earth Research Centre in Potsdam appears in this week's issue of the journal Science
"It is the first demonstration the magnetic fields generated by ocean flow can be detected by satellite," Tyler told ABC Science Online.
Salts in seawater form electrically-charged ions that generate electric currents, as well as magnetic fields, as they move. The British physicist Michael Faraday predicted this as far back as the 1830s but since then, only localised measurements of the phenomenon have ever been made.
The researchers used two years’ worth of data collected from the highly-sensitive German remote sensing research satellite, CHAMP, to measure magnetism in ocean currents......Click Here to Read More...
