Brain probe that softens after insertion causes less scarring
A hard probe inserted in the cerebral cortex of a rat model turns nearly as pliable as the surrounding gray matter in minutes, and induces less of the tough scarring that walls off hard probes that do...
View ArticleMice fed a high-fat diet show signs of artery damage after only 6 weeks
High fat diets cause damage to blood vessels earlier than previously thought, and these structural and mechanical changes may be the first step in the development of high blood pressure. These findings...
View ArticleEye research paves way for more successful cornea transplants
(Medical Xpress) -- Scientists at the University of Reading have made a significant breakthrough in cornea transplant research that could make future procedures more successful.
View ArticleThe neurological basis for fear and memory
Fear conditioning using sound and taste aversion, as applied to mice, have revealed interesting information on the basis of memory allocation.
View ArticleAdult stem cells from liposuction used to create blood vessels in the lab
Adult stem cells extracted during liposuction can be used to grow healthy new small-diameter blood vessels for use in heart bypass surgery and other procedures, according to new research presented at...
View ArticleImaging the network traffic in our brains
MRI brain scans no longer just show the various regions of brain activity; nowadays the networks in the brain can now be imaged with ever greater precision. This will make functional MRI (fMRI)...
View ArticleStudy of how eye cells become damaged could help prevent blindness
Light-sensing cells in the eye rely on their outer segment to convert light into neural signals that allow us to see. But because of its unique cylindrical shape, the outer segment is prone to...
View ArticleResearch poised to lead to major advances in cataract treatment
(Medical Xpress)—Research carried out by Professor Barbara Pierscionek and a team of fellow vision experts suggests that the way proteins are distributed in the lens of the eye may cause its gradient...
View ArticleResearcher provides insight into osteoarthritis
A researcher at The Feinstein Institute for Medical Research has discovered additional mechanical properties of articular cartilage, a protective cartilage on the ends of bones that wears down over...
View ArticleAn ear with the right look and feel
(Medical Xpress)—Like a fingerprint, their shape is so characteristic that one can identify us by them. The outer part of our ears has a complex structure that surgeons have a hard time replacing when...
View ArticleBuilding better brain implants: The challenge of longevity
On August 20, JoVE, the Journal of Visualized Experiments will publish a technique from the Capadona Lab at Case Western Reserve University to accommodate two challenges inherent in brain-implantation...
View ArticleNew technology that sorts cells by stiffness may help spot disease
The mechanical properties of cells are often an indicator of disease. Cancer cells are typically soft and squishy. When the malaria parasite is inside a red blood cell, for example, the cell is stiffer...
View ArticleResearchers model neural structures on the smallest scales to better...
Compared to the monumental machines of science, things like the International Space Station or the Large Hadron Collider, the human brain doesn't look like much. However, this three-pound amalgam of...
View ArticleOvarian cancer cells are more aggressive on soft tissues
When ovarian cancer spreads from the ovaries it almost always does so to a layer of fatty tissue that lines the gut. A new study has found that ovarian cancer cells are more aggressive on these soft...
View ArticleMutant models: Physics, statistics and genetics come together to reveal...
Nate Silver and Richard Feynman walk into a bar and bump into a biologist... While this may sound like the setup to some late-night nerd sketch, researchers have taken this premise and applied it to an...
View ArticleNew device could decrease time spent between detection and treatments for...
When treating cancer, time is the most important variable available for both the patient and the doctor. Time allows doctors to increase the knowledge of the specific cancer plaguing a patient. Time...
View ArticleThe more you run, the denser your bones will be
Spanish researchers have analysed the effect of endurance running training on the stiffness index, a variable that is directly related to bone quality. The results confirm that the greater the race...
View ArticleMyelination depends on mechanical as well as chemical signaling—new path to...
Mechanical forces play a critical role in myelination, the formation of the protective coating that neurons need to function, researchers at the University at Buffalo have discovered.
View ArticleNeurons feel the force—physical interactions control brain development
Researchers have identified a new mechanism controlling brain development: that neurons not only 'smell' chemicals in their environment, but also 'feel' their way through the developing brain.
View Article3-D-printable implants may ease damaged knees
A cartilage-mimicking material created by researchers at Duke University may one day allow surgeons to 3-D print replacement knee parts that are custom-shaped to each patient's anatomy.
