4 weeks after experiencing an electrical burn of 14,000 V to his left shoulder, a 42-year-old electrician arrived at the hospital complaining of vision problems. It turned out that the electric shock caused star-shaped cataracts to form over the patient's eyes’ lens. Cataracts, which are the clouding of lens, are often related to aging and occur in most adults by the time they’re 80 years old. Optometrists believe that the electrical current may have impaired the chemical balance in his blood, preventing proper blood flow to the optic nerves and retina — as well as impairing the fluid around the lens. Though he is still legally blind from the damage, surgeons removed the cataracts and implanted a new lens to somewhat improve his vision. A 48-year-old man suffered a motorcycle crash that left him with traumatic injuries — one of them being a remarkable 90-degree rotation of his heart. Doctors assume that a punctured lung caused air to expand into the area around his chest, pushing on his heart and leading to its rotation. After doctors drained the air 24 hours later, they were able to return the heart to its correct position — pretty much mostly uninjured, aside from a few blood vessels that were hurt by the movement. “I had never seen anything like it,” Dr. Gregory Fontana, chairman of the department of cardiothoracic surgery at Lenox Hill Hospital in New York City, said. He noted that the case was especially unusual due to the fact that the patient remained alert and awake, even though his heart had rotated so far. The patient was expected to recover completely from his injuries. In her photography project, “Topography of Tears,” Rose-Lynn Fisher sought to compose imagery of the structure of our tears — droplets induced by emotions like happiness, sadness, or fear — as well as a variety of biological elements like enzymes, proteins, and antibodies. Fisher photographed 100 different tears under a standard light microscope — each of them creating a completely unique pattern — then magnified them by 100x or 400x. “One day I wondered if my tears of grief would look any different from my tears of happiness — and I set out to explore them up close, using tools of science to make art and to ponder personal and aesthetic questions,” Fisher writes on her website. She examined tears from joy, laughing, sadness, onions, and frustration. “The random compositions I find in magnified tears often evoke a sense of place, like aerial views of emotional terrain.” What started out as a group of 5 women in Toronto, Canada who hoped to bring happiness to chemotherapy patients has turned into an organization of 150 artists worldwide who paint henna designs on the heads of women who’ve lost their hair to cancer treatment. Known as Henna Heals, the group of volunteers paint henna designs on cancer patients as a way to make them feel beautiful during their time of illness and ultimately, recovery. Henna paste is made with natural ingredients like fresh lemon juice, sugar, and Therapeutic Grade essential oils. These designs are known as “henna crowns,” and they offer the women a beautiful, intricate, and elegant way to overcome hair loss. Laura Kasperzak wasn’t expecting to become an Instagram celebrity of sorts after she began posting images of her yoga poses, often joined by her husband or children, but she now has a devoted following of over 1 million on her Instagram. Describing herself as a wife, mother, yoga teacher, and a “handstand addict,” Kasperzak has posted colorful photos depicting a variety of stunning yoga poses — with a focus on ones specially designed for couples and children. These photos serve to motivate and be a gentle reminder that yoga and exercising can be fun and a good way to bond with your friends and family. Researchers from the University of Maryland have developed a technique involving an airbrush to place biomaterials directly onto the skin in order to heal wounds. These nanofibers not only heal wounds, but they have the potential to become drug-releasing implants as well; they're biodegradable, meaning they can be accepted into the body quickly and safely. In the study, the researchers used these materials to fix lesions caused by diaphragm hernias and cuts in the lung, intestine, and liver of a pig. They found that within 24 hours, the cells had completely accepted the polymer. If further trials prove successful and researchers test this in humans, it could offer a less messy way to heal wounds and avoid stitches. The E10 Ultrasound, developed by GE Healthcare, offers an innovative view into the womb like never before – providing mothers with detailed and colorful imagery of their unborn child, as well as 3D and 4D images — essentially able to see through organs. Scientists believe the new sonogram could revolutionize fetal imagery; with the ability to provide quicker data transfer and better clarity. In a new study, researchers used a flexible material made of nanoribbons to create fake skin, which is able to decipher between hot and cold, wet and dry, and levels of pressure. While researchers in the past had developed ways to connect an amputee's brain to a prosthetic, to recreate sensations of touch, this is the first time researchers used a special stretchy material made of nanoribbons — a material so sensitive that it was able to distinguish between wet and dry baby diapers. Indeed, an artificial skin prosthetic could ultimately change the lives of amputees who would be able to sense heat, pressure, and humidity again. Source
Cool informative compilation. Thank you. I have found similar pictures at http://lafozi.com/us-en/ there are available a lot of photos on scientific and medical themes.
