Intentionally altering genomic DNA is a process that includes, but is not necessarily limited to, the use of genome editing technologies or genetic engineering to introduce desirable traits into organisms.

Researchers from the University of Maryland (UMD) are working to develop an electrogenetic device to direct gene expression, an achievement that holds promise for controlling biological systems and could help shape the future of biosensors, as well as wearable — and possibly implantable — bio-hybrid devices.

Rare and extinct animals are preserved in jars of alcohol in natural history museum collections around the world, which provide a wealth of information on the changing biodiversity of the planet.

Several studies have indicated that schizophrenic patients are likely to show a high level of nicotine dependence. Scientists from the Institut Pasteur, the CNRS, Inserm and the ENS used a mouse model to elucidate the mechanism of action of nicotine on cells in the prefrontal cortex. They visualized how nicotine has a direct impact on the restoration of normal activity in nerve cells (neurons) involved in psychiatric disorders such as schizophrenia. These findings were published in Nature Medicine on January 23, 2017.

Under ordinary circumstances, the protein tau contributes to the normal, healthy functioning of brain neurons. In some people, though, it collects into toxic tangles that damage brain cells. Such tangles are a hallmark of Alzheimer’s and other neurodegenerative diseases.

Technique enables rapid delivery of RNA to treat colon inflammation.

Salk scientists discover how to prevent undesirable immune attacks on therapeutic viruses

Medical implants like stents, catheters and tubing introduce risk for blood clotting and infection – a perpetual problem for many patients. Colorado State University engineers offer a potential solution: A specially grown, “superhemophobic” titanium surface that’s extremely repellent to blood. The material could form the basis for surgical implants with lower risk of rejection by the body.
