Scientists discover the secret to what makes us itch

What makes us itch?

Scientists  now know the secret. In what will be a boon for millions of people with chronic itch conditions, such as eczema and psoriasis, a small molecule released in the spinal cord has now been found to trigger a process that is later experienced in the brain as the sensation of itch.

Pacemaker under tongue may stop snoring

snoring

The Hypoglossal Nerve Stimulation System, works by stimulating the nerve which controls the muscles of tongue.

Scientists have come up with a new pacemaker-style device which they claim when implanted underneath one’s tongue could help stop snoring. A team claims that the new implant, called the Hypoglossal Nerve Stimulation System, works by stimulating the nerve which controls the muscles of tongue, thus helping reduce the severity of sleep apnoea, a major cause of snoring.

Vitamin D And Sun Exposure Play A Role In Disease Prevention

Vitamin D And Sun Exposure Play A Role In Disease Prevention

The sun is a natural and effective source of Vitamin D that we need to protect our bones, protect us from auto-immune diseases, help prevent Alzheimers disease, and protect us from certain kinds of cancers. Deficiencies in vitamin D are highly-linked to these diseases. Now, researchers at Emory University School of Medicine have found that Vitamin D deficiency is also linked to Parkinson’s Disease.

How Our Eyes Adapt To Movement

How Our Eyes Adapt To Movement 

When an object moves fast, we follow it with our eyes: our brain correspondingly calculates the speed of the object and adapts our eye movement to it. This in itself is an enormous achievement, yet our brain can do even more than that. In the real world, a car will typically accelerate or brake faster than, say, a pedestrian. But the control of eye movement in fact responds more sensitively to changes in the speed of fast moving objects than slow moving objects.

Improved Retinal Implant Stimulates Neurons To Restore Sight

Improved Retinal Implant Stimulates Neurons To Restore Sight 
A new retinal implant sits mostly outside the eye. 

For many blind or partially sighted people, implants that stimulate healthy nerve cells connected to their retinas could help restore some normal vision. Researchers have been working on such implants since the 1980s but with only limited success. A major hurdle is making an implant that can stay in the eye for years without declining in performance or causing inflammation.

Stem Cell Therapy Lessens Damage Caused By Stroke

Stem Cell Therapy Lessens Damage Caused By Stroke 

Stem Cell 

Until recently, the promise of stem-cell therapy has centered on stem cells’ ability to morph into virtually any kind of cells. But researchers are finding that stem cells may have other healing effects. In recent studies, scientists have observed stem cells acting as anti-inflammatory agents, reducing swelling and even scarring when administered to injured tissue.

Surgical Imaging System Turns Cancer Cells Neon

Surgical Imaging System Turns Cancer Cells Neon 

A real-time surgical imaging system (top) displays live video.  Image produced by the new system (bottom) shows a pig’s hind leg after injection of a contrast agent.  

Many cancer patients leave surgery still harboring dangerous tumor cells, while others suffer painful aftereffects because a surgeon has removed too much healthy tissue or nicked a nerve. A new imaging system that highlights cancerous tissue in lurid colors should help surgeons remove every last trace of cancer without harming the surrounding tissue. The system, currently in early clinical trials, uses a new class of contrast agents that emit near-infrared light and can attach to virtually any kind of tissue, cancerous or a healthy–showing surgeons just where to cut.

Diabetes Detected By Eye Test

Diabetes Detected By Eye Test

 A new eye test picks up fluorescence given off by dying cells in the retina, shown here.

A snapshot of the retina could detect cell damage in the early stages of diabetes.

Diabetes messes with the body’s metabolism, which can result in devastating complications like nerve damage, kidney disease, and vision loss.
