Iowa State University engineers have discovered a method where sugar is efficiently converted into a new type of nylon, by integrating a genetically engineered yeast strain with an electrocatalyst.
Diatoms are algae organisms comprising a single cell, and are sized from 30 to 100 millionths of a meter in diameter. They are scattered all-over the oceans, and have a hard shell made of silica. This shell resembles a flattened and wide cylinder like that of a tambourine.
Putnam Plastics Corporation, a leader in advanced extrusions and components for minimally invasive medical devices, has developed an advanced tri-layer tubing technology that significantly improves tensile and burst strength, while reducing elongation. Super-Tri™ tubing is made with a proprietary extrusion process and aids in the prevention of wire lock-up in catheters where guidewires are used.
Advanced tissue-engineering services now exist in North America, according to Cell Applications, Inc. and Cyfuse Biomedical K.K. These services have been made available due to the development of a novel three-dimensional (3D) bioprinting method known as the “Kenzan Method.”
Scientists have developed a new approach for the long-term storage of biological tissue and blood samples making blood transfusions easier.
In a recent episode of The Late Show, Stephen Colbert commented on a discovery made by zoologists from the University of Cambridge that Spider-Man probably couldn't climb walls. After intensive research, the zoologists found that natural adhesives scale in a way that geckos are the largest animals that can stick to walls and climb vertical surfaces.
Envisage a polymer that has removable parts and can be environment-friendly, and then can be chemically recreated to function again; alternatively, a polymer that is capable of lifting weights, and expanding and contracting, similar to muscles.
A team of researchers from Northwestern University have created a new biodegradable material integrated with vitamin A, which has the ability to prevent scarring in blood vessels.
A group of scientists from the Harvard John A. Paulson School of Engineering and Applied Sciences and the Wyss Institute for Biologically Inspired Engineering at Harvard University have developed a breakthrough 4D printing method, using time as fourth dimension. The group were inspired by plants and other natural structures, which react to environmental stimuli and change their form accordingly. The scientists have developed 4D printed hydrogel composite structures that change their form when immersed in water.
Esophageal cancer is the eighth most common form of cancer worldwide and treatment of this disease continues to be a major medical challenge. Despite improvements in surgical techniques, 50 to 60 percent of patients with esophageal cancer are not suitable for surgery, because of late tumor detection or metastases that cannot be removed with surgery.
