Researchers have succeeded for the first time in amplifying gene samples containing DNA adducts while retaining references to these adducts. This type of amplification is a prerequisite for the majority of technologies used by researchers to determine a gene's DNA sequence.
New therapies are on the horizon for individuals paralyzed following spinal cord injury - the e-Dura implant developed by EPFL scientists can be applied directly to the spinal cord without causing damage and inflammation.
Scientists reveal a new technique that focuses diffuse light inside a dynamic scattering medium containing living tissue. In addition, they have improved the speed of optical focusing deep inside tissue by two orders of magnitude.
New research shows that the genetic capacity of bacteria to make terpenes is widespread. Using a specialized technique to sift through genomic databases for a variety of bacteria, the researchers found 262 gene sequences that likely code for terpene synthases - enzymes that catalyze the production terpenes.
Researchers report on a revolutionary new procedure that uses 3-D printing and the body's stem cells to regenerate knee meniscus, a tissue lining that acts as a natural cushion between the femur and tibia.
Many genetic mutations in visual pigments, spread over millions of years, were required for humans to evolve from a primitive mammal with a dim, shadowy view of the world into a greater ape able to see all the colors in a rainbow. Now, after more than two decades of painstaking research, scientists have finished a detailed and complete picture of the evolution of human color vision.
In everyday life, the global positioning system (GPS) can be employed to reliably determine the momentary location of one en route to the desired destination. Scientists have now developed a molecular 'GPS' with which the whereabouts of metal ions in enzymes can be reliably determined. Such ions play important roles in all corners of metabolism and synthesis for biological products.
A new catalytic process is able to convert what was once considered biomass waste into lucrative chemical products that can be used in fragrances, flavorings or to create high-octane fuel for racecars and jets.
