A new handheld 3D printer can deposit sheets of skin to cover large burn wounds - and its 'bio ink' can accelerate the healing process. The device covers wounds with a uniform sheet of biomaterial, stripe by stripe.
Our skin protects us from physical injury, radiation and microbes, and at the same time produces hair and facilitates perspiration. Details of how skin cells manage such disparate tasks have so far remained elusive. Now, researchers have systematically mapped skin cells and their genetic programs, creating a detailed molecular atlas of the skin in its complexity.
Human fingers are sculpted from a primitive pad-like structure during embryonic development. Sometimes, this process goes awry and babies are born with fused fingers or toes. A new study reveals new factors involved in the congenital malformation called syndactyly.
In the dermis skin layer, the same bacteria are found across age and gender. This has been shown in a new study which has studied skin samples from knees and hips. The researchers hope it is a step in the direction of a better understanding of why skin disorders occur.
Bioengineers have developed a control system that could make CAR T-cell therapy safer and more powerful when treating cancer. By programming CAR T cells to switch on when exposed to blue light, the researchers controlled the cells to destroy skin tumors in mice without harming healthy tissue.
A cancer researcher has identified eight new genomic regions that increase a person's risk for skin cancer. Researchers have discovered eight new loci -- locations on a person's genome -- that are susceptible to the development of squamous cell skin cancer.
People rely on a highly tuned sense of touch to manipulate objects, but injuries to the skin and the simple act of wearing gloves can impair this ability. Scientists report the development of a new tactile-enhancement system based on a highly sensitive sensor. The sensor has remarkable sensitivity, allowing the wearer to detect the light brush of a feather. This crack-based sensor was inspired by a spider's slit organ.
Through experiments, researchers found that the force each cell applies to the surface beneath it -- in other words, traction -- is the dominant physical factor that controls cell shape and motion as cells travel as a group.
Following a premature birth it is important that the parents and the infant quickly establish a good relationship. Researchers have studied the relationship between mothers and infants who have continuous skin-to-skin contact during the entire period from birth to discharge from the hospital. The results show that continuous skin-to-skin contact does not lead to better interaction between the mother and the infant.
A study may help explain why previous attempts to develop a staph vaccine have failed, while also suggesting a new approach to vaccine design that focuses on activating an untapped set of immune cells, as well as inoculating against staph in utero or within the first few days after birth.
Popular gym chains across the country capitalize on the broad desire to get healthy in the New Year with persuasive post-holiday marketing campaigns, but they're also undermining public health warnings about the dangers of indoor tanning, according to a new study.
