Artificial Skin Update: Jelly Ingredient Could Help Amputees Feel Temperature Again

Artificial Skin Update: Jelly Ingredient Could Help Amputees Feel Temperature Again Pectin is used in cough drops, jams and all sorts of recipes. And now prosthetic limbs? Researchers have mixed the substance with water to create a film as thin as a human hair that can sense temperature, according to a statement from the California Institute of Technology, and can be used as an artificial skin for amputees and in high-tech bandages. The university explains that as the pectin heats, it releases calcium ions, producing a detectable electrical response. It also compares the process to how vipers sense their prey by detecting heat the creature is giving off. Read: Here’s Why Your Skin Doesn’t Leak “Pectin is widely used in the food industry … so it’s easy to obtain and also very cheap,” Caltech's Chiara Daraio, professor of mechanical engineering and applied physics, said in the statement. And the membrane is transparent and flexible, so it can be placed onto prosthetic limbs to help …

4 Possible Symptoms Of Asthma

Asthma, a chronic lung disease, affects more than 26 million people in the United States. Though there is no cure for the condition, one can manage symptoms to a significant degree with the help of medications and other recommendations. It is important to know about these potential signs so you can have your asthma diagnosed as soon as possible: 1. Breathlessness even when at rest Normally, workouts and other physical activities can leave us out of breath due to the energy expenditure. But people with asthma may experience breathlessness even during instances when they are not using much energy — say after walking or even while sitting. Rather than exercise, the patient may be facing this as a result of being exposed to irritants like tobacco smoke, dust, or animal fur. This would leave the airways inflamed even in a state of rest. Other possible triggers include emotional stress, weather changes, and certain medications. 2. Coughing that interrupts your sleep According to the National…

Winter Skin Care: Perfectil, Daily Pill, Clinically Proven To Reduce Fine Lines And Skin Roughness

As the cold winter months are fast approaching, with the promise of brisk air brushing up against the face, many women are getting ready to alter their skin care regime to prepare for the season’s harsh effects. This winter women can ditch the cream and lotion applicators, and opt for a simpler solution that only requires a pill and water. Perfectil, a daily pill containing micro-nutrients, could protect the skin against the fine lines and roughness caused by winter, according to a recent clinical trial. The change of the seasons always affects the skin, especially during the winter months. The skin tends to feel dehydrated, flaky, and rough with exposed areas, such as the face more prone to dryness in the so-called "T-zone area", which consists of the nose, chin, and forehead. Excessive dryness is often an indicator that the skin needs extra moisturizing and protecting from winter’s harsh effects. Discovery Fit & Health says in extreme weather — both hot and cold — cli…

Asthma In Children Isn't As Hereditary As Scientists Thought; Environment Plays A Larger Role

Asthma In Children Isn't As Hereditary As Scientists Thought; Environment Plays A Larger Role The risk of your child developing asthma just because it’s hiding somewhere in your family tree isn’t as threatening as scientists once thought it was. In one of the largest genetic asthma studies to date, researchers from the University of Chicago Medical Center examined the real risks of hereditary asthma and published their findings in the journal Nature Communications. "Previous studies have likely overestimated the heritability of asthma," said the study’s lead author Dr. Carole Ober, chair of the Department of Human Genetics at the University of Chicago, in a press release. "This could be because those estimates are based on correlations between family members that share environment as well as genes, which could inflate the heritability. Gene-environment interactions are not considered in these large scale association studies, and we know that these are particularly i…

Health Benefits Of Aspirin: How Acetylsalicylic Acid Relieves Pain, Reduces Inflammation. Should You Take Daily?

Most of us have used aspirin at some point in our lives, but have you ever stopped to think of how the little white pill is so effective at reducing pain? Luckily the team at How Stuff Works recently put together a YouTube video to help explain the science behind this widely popular drug. Although aspirin is a fairly new medical marvel, the drug itself is derived from the willow plant, which has been used as a painkiller for at least the past 6,000 years. As explained by How Stuff Works, it wasn’t until scientists worked on extracting and purifying the active ingredient in willow, salicin, that aspirin started to become what we know today. Aspirin helps to relieve the amount of pain we sense, and also reduces the inflammatory response to the point of injury. Photo Courtesy of Pixabay In our digestive tract, salicin is broken into salicylic acid, which helps to reduce pain  and inflammation. German scientists were able to synthesize this on a large scale, but unfortunately it was very …

Top Eczema Triggers to Avoid

Top Eczema Triggers to Avoid
1/12 Some Chemicals To steer clear of those that can make eczema itchy and to keep your skin happy: Wear cotton-lined gloves when cleaning.Don't use air fresheners, perfume, or scented candles.Stay away from smoke.

When you’re done, gently pat your skin -- don't rub -- until it’s just damp. Then, slather on thick lotion right away to lock in moisture. Check the ingredients label of your lotion. If you’re allergic to wool, lanolin will irritate your skin. No wool allergy? Lanolin helps. 3/12 The Sun, Sweat, and Sunscreen You can be out in the sun, but your skin may not like getting hot and sweaty. If so, stay cool and seek out shade. Always wear sunscreen. Sunburns inflame your skin and can lead to an eczema flare. If you’re sensitive to sunscreens, block out burning rays with mineral versions, like z…
