A new 3D printed “Bionic Skin” developed at the University of Minnesota, is a stretchable, electronic fabric, which would allow robots to gain tactile sensation. The results of this study were published in the journal, Advanced Materials. Scientists have been dreaming of artificial skin since the 1970’s. Thanks to funding by a division of the National Institutes of Health, we are much closer to making it a reality.

Michael McAlpine was the lead researcher on this study. He’s a mechanical engineering associate professor at the university. In 2013, while at Princeton, McApline gained international attention for 3D printing nano-materials to fashion a “bionic ear.” For this project, Prof. McAlpine enlisted graduate students Shuang-Zhuang Guo, Kaiyan Qiu, Fanben Meng, and Sung Hyun Park.

Dr. McAlpine and his team created a unique 3D printer unlike any in the world. The device has four nozzles, each with several different functions. To print on the skin, the surface is first carefully scanned for its contours and shape. The printer can follow any curvature. Then, once the surface area has been mapped out precisely, printing can begin. McApline and colleagues were able to print a pressure sensor on a mannequin’s hand.

The base of the “skin” is silicone which when distributed via nozzle, came out as a gel. This contains silver particles to help conduct electricity. A coiled sensor was then printed in the center. Following that, the piece was engulfed in more silicon layers. Above and below the sensor lay electrodes in the form of a conductive ink. At last, a final, temporary layer was printed to hold everything together, while it solidified. The whole thing was just 4-millimeters wide and took mere minutes to carry out. Once it dried, the last layer was washed away, revealing a…

11 Easy Ways to Fix Your Whole Life This Summer

Summer is the season of getting in shape mentally, physically, and financially. But forget making drastic personality changes, devoting hours of extra time to sweating at the gym, or forking over loads of cash. Sometimes the most dramatic lifestyle shifts are the result of tiny decisions we make every day. Here are 11 little lifestyle changes that’ll get your whole life fit for summer — and the rest of the year, too.

1. Clean your cell phone daily

I hate to gross you out, but that phone in your pocket is literally teeming with germs. Various studies have found E. coli, MRSA, Streptococcus, and many other pathogens living on mobile phones. Keep yourself healthy by wiping down your phone thoroughly each day with a dry microfiber cloth. Disinfect it weekly using a microfiber cloth dampened with diluted isopropyl alcohol.

2. Switch to a moisturizer with sunscreen

Even on an overcast day, the sun can damage skin. Using moisturizer with SPF 30 or greater can shield your skin from harmful UV rays, slow the development of wrinkles, minimize redness, and reduce the risk of skin cancer — all without adding another step to your morning routine.

3. Cut out soda

A 12-ounce can of regular soda contains roughly nine teaspoons of sugar (about the same amount as 2.5 scoops of ice cream). Just this single dietary change will help you maintain a healthy weight, reduce your risk of developing type-2 diabetes, and minimize dental problems.

4. Socialize

Humans are social animals. Spending time with close friends improves your mood, increases self-confidence, and helps you navigate life’s ups and downs. Instead of relying on random get-togethers, make a weekly date to spend quality time…

Do You Know Tea Tree Oil is Very Useful For Acne and Hair?

You’ve probably heard of the powerful anti-bacterial properties of tea tree oil especially when it comes to our skin. Also known as melaleuca oil, tea tree oil is made from the leaves of the plant Melaleuca alternifolia commonly found in Australia.

So, how can we really benefit from this amazing, natural remedy?

The Benefits Of Tea Tree Oil

Don’t just take people’s word for the amazing power of tea tree oil. Many scientific studies 1 have been conducted in order to prove just how beneficial this oil is.

Its exceptional healing properties mean it can have several different uses.

Tea Tree Oil For Acne

This oil can help heal many forms of skin conditions including acne, rashes, eczema, and fungal infections but acne is the most common association with tea tree oil. This is because it contains strong antibacterial and antifungal compounds which penetrates the skin and unblocks sebaceous glands. This has led to studies that have found tea tree oil to be as effective as benzoyl peroxide 2 but without the harshness.

On top of that, it can help against scarring which is a common side effect from continuous acne on the face and body.

Tea tree oil is known for soothing dry scalp and for getting rid of unsightly dandruff 3. It also helps unclog hair follicles and nourishes the roots of the hair which helps your hair to grow more strong and healthy.

For those with kids who are prone to getting head lice, tea tree oil has even been found to kill lice as well as reducing the number of eggs that hatch making it a more natural way to tackle this common problem 4.

Tea Tree Oil For Cuts And Infections

Because tea tree oil is anti-bacterial, it makes an amazing natural way to clean any cuts and tackle any infections found in wounds.

It can also deal with fungal infection such as toenail fungus, ringworm and athlete’s foot as it’s so effective…

Irritated by Whiteheads on Your Face? Here Are Some Quick And Easy Ways To Help!

Is all the makeup you use to hide your whiteheads putting a dent in your budget?

Whiteheads are those annoying little white spots that occasionally pop up on your skin, seemingly for no reason. Your body plays host to these little nuisances, but for most folks their bodies can’t seem to find the right way to tell those whiteheads they have long overstayed their welcome. No matter what treatments you use or how often you wash your face, those tiny, white volcanic blips just won’t budge.

And it’s a frustration that millions of people experience at some point.

What is actually happening when whiteheads appear?

Whiteheads are type of acne characterized by their white bumps that raise above the skin’s surface. When a whitehead appears on your skin, it means that excess oils from the sebaceous glands have clogged your pores or hair follicles in that particular spot. The oils, along with bacteria and other debris, become trapped and eventually manifest as a spot on your skin.

These spots appear white because the oils and debris within are sealed from the outside air. If that seal were to break, then the whiteheads would turn darker and become blackheads (another beauty bane that is seemingly impossible to get rid of).

What are the probable causes of whiteheads?

There is no singular cause for whiteheads, which can make it harder to determine why you get them. Here are a few possible culprits:

During pregnancy, your body sends your hormones haywire, which means that “normal” functions are a temporary thing of the past. These hormonal changes can cause your body to up its production of the sebaceous oils, which eventually show up on your face and body.

As if growing up weren’t difficult enough, the hormonal changes as teens transition into adulthood contribute to frequent outbreaks of many forms of acne, including whiteheads. Just like with pregnancy, the body may produce excess sebaceous oils that cause whiteheads to form.

Even small, infrequent hormonal changes,…

Irritated by Dandruff? No Worries We Are Here To Help You!

Dandruff is a perfectly common condition, but it doesn’t make experiencing those little white flakes on your shoulders any less embarrassing. Even though we may know many people share our frustration with the dry flakes of skin falling onto our dark clothing in a business meeting or first date, it feels so personal in the moment, and it can be hard to ignore the way you feel.

Dandruff can be a tricky thing to deal with, as it has numerous causes. Along with the most common causes, dry skin and psoriasis, it is supposedly caused by not cleaning your scalp often enough, or cleaning it too often. To make this even more frustrating, some people say it can also be caused by simply shampooing with something your sensitive scalp doesn’t like. So how are you supposed to deal with it. And what exactly is dandruff, really?

What’s going on up there?

Part of the embarrassment of dandruff is the misunderstanding behind it; a lot of people believe that dandruff is caused by poor hygiene. But this isn’t scientifically sound. In fact, experts agree this is probably the last thing responsible for those flakes. Dandruff is a skin condition, first and foremost. It causes your scalp, and the scalps of 50% of the population, to flake off in tiny little pieces and usually comes with some itching. It’s closely linked to something called Malassezia. This is a fungus that everyone has (sorry) on their scalps and it feeds on the oils secreted by hair follicles. This can cause skin cells to shed and clump into those annoying flakes 1.

Surprisingly, dandruff doesn’t just happen on your scalp. In fact, you can get dandruff on your face. Plenty of people discover dandruff in their eyebrows, around their ears and even on their noses. Basically, if your skin produces oil, it’s at risk of producing dandruff 2.

Regardless of where you experience it, before you run to the store to purchase dandruff shampoo, make sure you are truly experiencing dandruff, and not something else. Beverly Hills dermatologist Stuart H Kaplan, M.D. recommends a medicated dandruff shampoo that contains ketoconazole, selenium sulfide or zinc. If you don’t see any improvement after two weeks of using the ‘poo, you may want to consult a physician. You could have psoriasis or another skin inflammation.

The Causes of Dandruff.

Some studies have found diet can impact your risk for dandruff, claiming people who eat lots of salt, too much sugar or foods rich in spice can experience more dandruff than a person with a healthier diet. Excessive alcohol use can also lead to flaking skin. However, with a significant number of dandruff sufferers claiming it seems to get better as they age, the jury was out as to whether it really is caused by what you’re eating or if it’s just something we all have to experience. That is until 2007.

In 2007, scientists found that the fungal yeast responsible for dandruff produces enzymes which break down oils produced by our sweat glands. This creates an acid which penetrates the top layer of our skin and triggers cells to be created faster…

Girl Bullied For Having Vitiligo Turns Her Skin Into Art

Ash Soto was diagnosed with vitiligo when she was 12. As her vitiligo started spreading, she began to feel ashamed of her skin, especially after a little girl asked her if she had showered in bleach. Now the 21-year-old not only isn’t ashamed, but she embraces her skin.

In her late teens, Soto decided she wouldn’t let her skin hold her back anymore, so she started setting herself daily challenges like walking in public without a long sleeve shirt. Eventually, the challenges led to Soto turning her body into beautiful art. “I never realized how beautiful my vitiligo was until I traced it with a black marker, it really helps to bring out the different colors of my skin,” Soto said to Daily Mail. Now, she has made her body look like so many different art pieces, including Van Gogh’s Starry Night, and she’s not stopping! “Now what others would perceive as an imperfection I have made into something…
