For the first time in history, a patient has been given a new trachea made from a synthetic scaffold seeded with his own stem cells. The patient, a 36-year old man, is well on the way to full recovery from the recent operation in Sweden and is now being discharged from the hospital.
(PhysOrg.com) -- Scientists at the University of Glasgow have, for the first time, been able to drag light by slowing it down to the speed of sound and sending it through a rotating crystal.
For the first time, blood vessels created in the lab from donor skin cells were successfully implanted in patients. Functioning blood vessels that aren
A tiny biological fuel cell, the smallest of its kind (0.3 microliters), has been built by researchers at Carnegie Mellon University (CMU), powered by
Researchers have used cutting-edge stem cell technology to correct a genetic defect present in a rare blinding disorder, another step on a promising path that may one day lead to therapies to reverse blindness caused by common retinal diseases.
The quest for better ways of encapsulating medicine so that it can reach diseased parts of the body has led scientists to harness -- for the first time -- living human cells to produce natural capsules with channels for releasing drugs and diagnostic agents.
Scientists have discovered a new type of cell in the immune system. The new cell type, a kind of white blood cell, belongs to a family of T-cells that play a critical role in protection against infectious disease. Their findings could ultimately lead to the development of novel drugs that strengthen the immune response against particular types of infectious organisms.
In the search for superconductors, finding ways to compress hydrogen into a metal has been a point of focus ever since scientists predicted many years ago that electricity would flow, uninhibited, through such a material.
Three molecules thick, or two, or one: how does an extremely thin layer of trapped liquid behave when we make it even thinner? Measurements made using the atomic force microscope show that the forces of friction increase with each step. Liquids begin to behave more like a gel, according to new research.
Millions of people with knee injuries could benefit from a new type of stem cell bandage treatment if clinical trials are successful. The world
Researchers at the Stanford University School of Medicine have found that human skin cells can be converted directly into functional neurons in a period of
A new biomaterial that closely mimics the properties of native human tissue to repair damaged human tissue, such as heart walls, blood vessels, and skin,
In a significant medical prothesis breakthrough, Rob Summers, 25, a pitcher for Oregon State University who was completely paralyzed below the chest five
Watching things disappear is an amazing experience. But making items vanish is not the reason scientists work to create invisibility cloaks. Rather, the magic-like tricks are attractive demonstrations of the fantastic capabilities that new optical theories and nanotechnology construction methods now enable.
