If you opt to wear soft contact lenses, chances are you are using hydrogels on a daily basis. Made up of polymer chains that are able to absorb water, hydrogels used in contacts are flexible and allow oxygen to pass through ...
Researchers have obtained bioceramics from shark teeth, which have applications in the regeneration of bone tissue, particularly in the fields of traumatology and odontology. Given the degree of innovation and the positive ...
Few organs in the body are as complicated as the human brain, a tight spiderweb of neurons that shoots electrical signals across synapses to control all our thoughts and movements. When something goes wrong—as it does when ...
(Phys.org)—Given that blood supply to the brain and spinal cord is fundamental to central nervous system (CNS) physiology and pathology, it's not surprising that trauma and disease in spinal cord blood vessels and neurons ...
A new laboratory tool which will allow scientists to build and move microscopic cells could lead to the development of better treatments for disease.
Duke University researchers have devised a method to activate genes in any specific location or pattern in a lab dish with the flip of a light switch by crossing a bacterium's viral defense system with a flower's response ...
Japanese scientists say they are on their way to being able to create custom-made skin, bone and joints using a 3D printer.
On Friday, NASA successfully launched its next-generation spaceship farther than any astronaut has flown since the Apollo program of the 1960s. Though the Orion was unmanned during the test flight, which took it 15 times ...
There are plenty of body parts that don't grow back when you lose them. Nails are an exception, and a new study published in the Proceedings of the National Academy of Sciences (PNAS) reveals some of the reasons why.
While investigating a rare genetic disorder, researchers at the University of California, San Diego School of Medicine have discovered that a ubiquitous signaling molecule is crucial to cellular reprogramming, a finding with ...
