The year that just passed has been an amazing year for science, with many breakthroughs that will shape the future of humanity so let’s recap the most important medical discoveries of 2015.
Scientists grew vocal cords from scratch
Scientists have built the first set of vocal cords out of some cells from human donors. They managed to make the cells grow tissue which resembles the vocal fold mucosa which creates the sound of human voice. This could give a voice to millions of people who have lost their vocal cords as a result of accident or illness.
A potential male birth control pill
Scientists have identified two different drugs – cyclosporine A (CsA) and tacrolimus (FK506) which could work as male birth control pills. The combination of the two drugs makes the sperm too rigid to penetrate the membrane around the egg, making conception an impossible mission.
Researchers managed to develop yeast which can produce THC, the active compound in marijuana. Other versions of synthetic THC already existed but this is the cheapest way to produce it which might help researchers study its health benefits even further.
3D-Printed Ribs and Sternum
Through a revolutionary surgical procedure a 54-year-old with chest wall sarcoma received the first custom 3D-printed set of ribs and sternum. The only way of removing the tumour that was threatening his life was by removing his sternum and a part of the ribcage. Anatomics, a medical device company from Australia 3D-printed the set of ribs and sternum using CT scans of the man’s chest.
The first bionic penis
Mohammed Abad has lost his penis when he was six years old, after being in a car accident. Scientists at the University of London have been working for three year to give the man a new penis made of his own skin taken from his forearm. The organ is 8-inch long and becomes erect by pushing a button.
An artificial pancreas has been developed by scientists with the aim of being implanted to patients with type 1 diabetes. The artificial organ can measure and regulate the levels of blood sugar by releasing insulin as needed.
Perfect vision is possible with the help of some newly invented Ocumetics Bionic Lens developed by Dr. Garth Webb, an obtometrist from British Columbia. The lens can be implanted in an 8-minute surgery and give anyone perfect vision without the need of ever wearing glasses again.
