A quadriplegic man in the US has been able to use his right arm and hand again after eight years of paralysis. Bill Kochevar, who was paralysed below his shoulders in a cycling accident, was able to do this thanks to a neuroprosthesis. Electrodes implanted under his skull record brain activity in his motor cortex region, sending signals to electrodes in his arm that tell them when to stimulate his muscles. The device has enabled him to raise a mug of water and drink from a straw, and scoop mashed potato from a bowl. “For somebody who’s been injured eight years and couldn’t move, being able to move just that little bit is awesome to me,” says Kochevar. In preparation, Mr Kochevar first learned how to use his brain signals to move a virtual-reality arm on a computer screen. “He was able to do it within a few minutes,” says Bob Kirsch, from Case Western Reserve University, in Cleveland, Ohio. “The code was still in his brain.” After four months of practice, he could take control of his own arm and hand, with the help of a mobile support that stops gravity from getting in the way. Kochevar isn’t the first paralysed person to regain control of an arm and hand. Last year, Ian Burkhart was able to pick up and pour a bottle, and even play the Guitar Hero computer game, thanks to a brain implant connected to an external sleeve of electrodes placed over his arm. In 2015, a brain implant enabled Erik Sorto to drink a beer at his own pace using a robotic arm. But restoring movement to paralysed people isn’t the only goal. One team has made a mind-controlled robotic arm that actually feels like a person’s own hand, sending sensations back to a quadriplegic person’s brain. Brain implants have also let a locked-in woman with amyotrophic lateral sclerosis (ALS) communicate by thought alone.

Some want the correction of an accident or deformity. Many desire reconstructive surgery for skin cancer. Others simply want to grow old gracefully, but everyone wants to look as good as they feel. Besides improving appearance and helping you feel better about yourself, there are health benefits of plastic surgery that most individuals aren’t aware of. Plastic surgery can improve breathing, vision, neck and back pain, self-esteem and self-confidence, and according to many studies, even increase your income. Did you ever wonder if you could breathe better and have a straighter or more contoured nose? Plastic surgery can improve your breathing. I see many patients with stuffy nasal breathing, snoring and sinus problems.

The types of plastic surgery and augmentation procedures we see today were already used by surgeons back in the early 1800s.
Although the tools and techniques used in such surgeries have evolved dramatically over the past few decades, the basics of such surgeries are still the same as in the 18th century. People have always been concerned about their outer appearance since the beginning of civilization. To offer such people a better look, doctors of the ancient times also took the efforts to find out new ways of performing esthetic surgeries.

Each bit is encoded using the magnetic field of a single atom — making for extremely compact data storage, although researchers have stored only two bits of data so far.
“If you can make your bit smaller, you can store more information,” physicist Fabian Natterer of the École Polytechnique Fédérale de Lausanne in Switzerland said March 16 at a meeting of the American Physical Society. Natterer and colleagues also reported the result in the March 9 Nature.

Q. What is the difference between cosmetic and plastic surgery? A. Cosmetic surgery is a unique discipline of medicine focused on enhancing appearance through surgical and medical techniques. Cosmetic surgery can be performed on all areas of the head, neck and body. Because treated areas function properly but lack aesthetic appeal, cosmetic surgery is elective. Plastic surgery is defined as a surgical specialty dedicated to reconstruction of facial and body defects due to birth disorders, trauma, burns, and disease. Plastic surgery is intended to correct dysfunctional areas of the body and is reconstructive in nature.

The method involves transforming the most common type of cells found in wounds into fat cells -- something that was previously thought to be impossible in humans.

Researchers are now reporting, however, that they have found a way to produce cartilage tissue by 3-D bioprinting an ink containing human cells, and they have successfully tested it in an in vivo mouse model.

The eyelid crease is an important landmark in eyelids. Its presence, height and contour can dramatically alter the way an eyelid appears. Half of patients of Oriental descent lack an eyelid crease, whilst the remaining half do have a crease of some description. Because of the way an eyelid crease alters the appearance of an eyelid giving the appearance of two parts to the eyelid i.e. those above and below the crease, some have termed eyelids with creases as 'double eyelids' and those without creases as 'single eyelids'.
