The loss of complete segments of the esophagus often results from treatments for esophageal cancer or congenital abnormalities, and current methods to re-establish continuity are inadequate. Now, working with a rat model, researchers have developed a promising reconstruction method based on the use of 3D-printed esophageal grafts.
Snails can anchor themselves in place using a structure known as an epiphragm. The snail's slimy secretion works its way into the pores found on even seemingly smooth surfaces, then hardens, providing strong adhesion that can be reversed when the slime softens. Penn Engineers have developed a new material that works in a similar way.
A therapeutic gene delivered into the spinal canal of infant rhesus monkeys was still being expressed after nearly 4 years, with no evidence of acute or chronic neuronal tox-icity, according to a new study published in Human Gene Therapy.
Cornell University engineers have taken a step in understanding how iron in the soil may unlock naturally occurring phosphorus bound in organic matter, which can be used in fertilizer, so that one day farmers may be able to reduce the amount of artificial fertilizers applied to fields.
Inspired by snail biology, scientists at the University of Pennsylvania, Lehigh University and the Korea Institute of Science and Technology have created a super-glue-like material that is 'intrinsically reversible.' In other words, it can easily come unglued. They have reported their findings in a paper published today in Proceedings of the National Academy of Sciences.
Scientists from the University of Massachusetts Amherst, Vanderbilt University and Clark University have shed new light on the genomic foundation of the polar bear's ecological adaption by pinpointing rapid changes in the bear's gene copy numbers in response to a diet shifting from vegetation to meat.
Physicists from the Immanuel Kant Baltic Federal University conduct a study on nanomaterials that have been synthesized by the method of the electric explosion. Research group of the Laboratory of Novel Magnetic Materials has studied the magnetic and structural properties of metallic α-Fe magnetic nanoparticles, which were covered with non-magnetic iron oxide.
To get a better reading on your overall health and wellness, you'd be better off looking at the strength and structure of your circle of friends, according to a new study in the Public Library of Science journal, PLOS ONE.
EPFL scientists have discovered a new type of 2D magnetic material that can be integrated into spintronic devices.
Indium-gallium-zinc oxide ceramics are used as the backplane for flat-panel displays, this was made possible through substantial synergistic contributions coming from the powerhouse that is Japan. A team of researchers from Japan reports the synthesis of centimeter-scale single crystals of a particular type of these semiconductors, InGaZnO4 (IGZO-11), with attractive characteristics such as wide band gap and high electrical mobility and conductivity, which make it promising candidates for transparent optoelectronic devices like touchable displays and organic LEDs.
