Researchers from EPFL and the University Medical Center Utrecht in the Netherlands have developed an extremely fast optical method for sculpting complex shapes in stem-cell-laden hydrogels and then vascularizing the resulting tissue. Their groundbreaking technique stands to change the field of tissue engineering.
Now, researchers have shown that it is possible to evoke a shift in the metabolism from fermentation to respiration of E. coli and baker's yeast by optimizing fermentation conditions. This shift means that the cells can be pushed into producing more internal energy (ATP).
Japanese scientists at Tokyo University of Agriculture and Technology (TUAT) have found that for stroke patients, observing their own hand movements in a video-assisted therapy -- as opposed to someone else's hand -- could enhance brain activity and speed up rehabilitation.
For the first time, an HZB team has derived analytically how corkscrew-shaped nano-antennas interact with light. The mathematical tool can be used to calculate the geometry that a nano-antenna must have for specific applications in sensor technology or information technology.
A sophisticated chip the size of a coin in which cartilage can be cultivated and which can later be subjected to mechanical stress such that it generates the effects of Osteoarthrosis (OA).
Injuries to nerve fibers in the brain, spinal cord, and optic nerves usually result in functional losses as the nerve fibers are unable to regenerate. A team from the Department of Cell Physiology at Ruhr-Universität Bochum led by Professor Dietmar Fischer has deciphered new mechanisms that enable the regeneration of such fibers. This could open up new treatment approaches for the brain, optic nerve, and spinal cord injuries.
An international group of scientists studied the effects of 17 different lifespan-extending interventions on gene activity in mice and discovered genetic biomarkers of longevity. The results of their study were published in the journal Cell Metabolism.
Researchers at the University of Health Sciences, Medical Informatics and Technology (UMIT, Hall, Austria) and the University of the Balearic Islands (Palma de Mallorca, Spain) have confirmed the analgesic effects of social support - even without verbal or physical contact.
Researchers at the University of Copenhagen have developed a prototype of an app that may potentially prescribe the optimal dose of medicine for the individual patient, as well as prevent counterfeit products.
Despite the fact that people in sub-Saharan Africa are now living longer than they did two decades ago, their average life expectancy remains below that of the rest of the world population. A new study looked into the importance of various causes of death in Zambia and how eliminating the most prominent of these would impact life expectancy in the country.
