Currently, two clinical trials have been performed (NEST1 and NEST 2) with a third underway.  Results of the...

The discovery could take us a step closer to magnetic memory devices with capacities thousands of times denser than current high-end hard drives. Clouds from both sides – Atmospheric and climate models may have overlooked the fact that exactly how clouds appear to reduce the amount of sunlight available for warming the surface of the earth depends on the wavelength being measured across the spectrum from infrared to ultraviolet. The finding could now help researchers improve climate models by factoring in the effects of cloud cover more precisely.

The findings could have implications for developing new approaches to neurodegenerative diseases, such as multiple sclerosis. Cancer transition – Anticancer drugs for treating ovarian and colon cancer could use rare metals as weapons in the battle against these diseases. The presence of unusual metal centres in organometallic compounds presents a novel affront to tumour cells that may even beat cancer cells that have evolved resistance to conventional drugs. 17th century mathematics and 21st century materials – Nanoparticles ca...

Can this technology be used to detect obstructive sleep apnea?Typically, contact sensors are placed around your nose and mouth to measure airflow during a sleep study. The authors report that these sensors and wires may cause discomfort during sleep.The advantage of thermal infrared imaging is that it uses “non-contact” sensing to detect airflow abnormalities. It is unobtrusive and doesn’t touch your body while you sleep.The automatic thermal moni­toring system (ATHEMOS) uses an infrared camera to record your sleep from a distance. It acquires ther­mal information as heat radiates from your nostrils.The thermal signature...

The compound, the antioxidant ergothioneine, could be used as a biomarker for the potentially fatal condition, pre-eclampsia, which can cause severely raised blood pressure during pregnancy, according to the researchers, although they explain that the compound is probably not the cause of the disorder. NIR improvements near – Spectroscopy, forensic science and even a future generation of quantum communication devices could benefit from research at the National Institute of Standards and Technology (NIST).

OS is caused by a chemical imbalance that can damage critical components of cells and biofluids, including proteins, lipids and DNA. OS is known to be involved in many neurological diseases, including Alzheimer's and Parkinson’s disease.In differentiating Alzheimer’s disease patients from the normal elderly control group, NIR achieved a sensitivity of 80% and specificity of 77%. Fifteen and twelve patients with mild cognitive impairment were classified with the normal elderly co...

The Daily Mail reports that the helmet bathes the wearer with infra-red light. The helmet only needs to be worn for ten minutes each day. Dr Dougal claims that only ten minutes under the hat a day is enough to have an effect. "Currently all you can do with dementia is to slow down the rate of decay - this new process will not only stop that rate of decay but partially reverse it," he said. Low level infra-red red is thought to stimulate the growth of cells of all types of tissue and encourage their repair. It is able to penetrate the skin and even get through the skull. "The implications of this research at Sunderland are enormous - so much so that in the future we could be able to affe...

Alster and Tanzi of the Washington Institute of Dermatologic Laser Surgery in Washington, DC, has demonstrated the efficacy of a novel combination approach to treating cellulite. Their method involved the combination of radiofrequency, infrared light, and mechanical tissue manipulation to improve cellulite. According to the published work, the method involved “Twenty adult women (ages 25-57 years) of various skin phototypes (I-V), and with moderate bilateral thigh and buttock cellulite, received eight biweekly treatments to a randomly selected side (the contralateral side serving as a non-treated control). A combined bipolar radiofrequency, infrared light, and mechanical suction-based massage device was applied at 20 watts RF, 20 watts IR (700-1500...

Encouragingly, early detection and proper treatment of a foot ulcer can prevent up to 85 percent of amputations. It is important for physicians to perform regular, thorough foot exams, however people with diabetes can also rely on a foot thermometer for early detection of inflammation and potential ulceration. Xilas Medical Inc. manufacturers the TempTouch (R), an infrared temperature measurement device for at-home use. In previous clinical trials, TempTouch (R) successfully detected inflammation before an ulceration perforated the surface skin. Patients compared temperatures of each foot in like positions...

We have heard Syneron has received FDA approval for their ELOS device for the treatment of cellulite, and now a new study from Thailand discusses the efficacy of RF for cellulite treatment. The Department of Dermatology at Siriraj Hospital, Mahidol University in Bangkok, Thailand performed a research study on 12 patients with a RF-light based device. The subjects were treated twice weekly for a total of eight to nine treatments. According to the study, “Subjects were evaluated using standardized photographs, and measurements of body weight and circumference of treatment sites at baseline, immediately after the last treatment, and four weeks and one year after the last treatment.

An infrared therapy is showing promising results for the reduction of pain from peripheral neuropathy. Anodyne Infrared Therapy is a treatment that uses light energy to exponentially increase (up to 400%) the circulation in peripheral areas (arms, legs). Light-emitting diodes are fitted into flexible pads that can be applied directly to the skin on any affected part of the body. The light energy helps increase blood flow by delivering nutrients to the injured site. Anodyne therapy consists of 10 to 12 sessions ...
