Using an off-the-shelf camera flash, researchers turned an ordinary sheet of graphene oxide into a material that bends when exposed to moisture. They then used this material to make a spider-like crawler and claw robot that move in response to changing humidity without the need for any external power.
Researchers compared the thickness of brain cortex in patients with brain tumors before and after radiation therapy was applied and found significant dose-dependent changes in the structural properties of cortical neural networks, at both the local and global level.
Researchers have more evidence that males and females are different, this time in the fluid that helps protect the cartilage in their knee joints.
This latest research led by CMU's Marcel Just builds on the pioneering use of machine learning algorithms with brain imaging technology to "mind read." The findings indicate that the mind's building blocks for constructing complex thoughts are formed by the brain's various sub-systems and are not word-based.
A new study in the journal Health Affairs shows that, despite being designed to more effectively manage care and control costs, black patients enrolled with Medicare Advantage are far more likely to be readmitted to the hospital after a surgery than those enrolled on traditional Medicare. Furthermore, significant disparities continue to exist in readmission rate between black and white Medicare patients.
The ongoing deforestation around the fringes of the Amazon may have serious consequences for the untouched deeper parts of the rainforest. A new research study shows that it is not only the climate that is adversely affected by deforestation. In fact, the very stability of the ecosystem in the entire Amazon region is altered when deforestation takes place in the outermost regions.
A Georgia Tech study suggests Uranus' magnetosphere, the region defined by the planet's magnetic field and the material trapped inside it, gets flipped on and off like a light switch every day as it rotates along with the planet. It's 'open' in one orientation, allowing solar wind to flow into the magnetosphere; it later closes, forming a shield against the solar wind and deflecting it away from the planet.
A new study from North Carolina State University finds that common wild bee species decline as urban temperatures increase.
Important pieces of the puzzle to understand what drives diseases such as Alzheimer's and Parkinson's are still missing today. One crucial obstacle for researchers is that it is impossible to examine a living brain cell in someone who is affected by the disease. With the help of a new method for cell conversion, researchers at Lund University in Sweden have found a way to produce diseased, aging brain cells on a large scale in a cell culture dish.
Carbon nanotubes exhibit interesting characteristics rendering them particularly suited to the construction of special hybrid devices -- consisting of biological issue and synthetic material -- planned to re-establish connections between nerve cells, for instance at spinal level, lost on account of lesions or trauma. This is the result of a piece of research published on the scientific journal Nanomedicine: Nanotechnology, Biology, and Medicine.
