DNA microscopy offers entirely new way to image cells
19.6.2019 | Press monitoring
Traditionally, scientists have used light, x-rays, and electrons to peer inside tissues and cells. Today, scientists can trace thread-like fibers of nerves throughout the brain and even watch living mouse embryos conjure the beating cells of a rudimentary heart. But there's one thing these microscopes can't see: what's happening in cells at the...

First-ever spider glue genes sequenced, paving way to next biomaterials breakthrough
17.6.2019 | Press monitoring
UMBC postdoctoral fellow Sarah Stellwagen and co-author Rebecca Renberg at the Army Research Lab have published the first-ever complete sequences of two genes that allow spiders to produce glue – a sticky, modified version of spider silk that keeps a spider's prey stuck in its web. The innovative method they employed could pave the way for...
CRISPR-associated transposons able to insert custom genes into DNA without cutting it
14.6.2019 | Press monitoring
A team of researchers affiliated with the Broad Institute of MIT and Harvard, MIT and the National Institutes of Health has found that CRISPR-associated transposons can be used to insert custom genes into DNA without cutting it. In their paper published in the journal Science, the group describes their new gene-editing technique and how well it...

DNA nanorobots target HER2-positive breast cancer cells
12.6.2019 | Press monitoring
According to the Mayo Clinic, about 20% of breast cancers make abnormally high levels of a protein called human epidermal growth factor receptor 2 (HER2). When displayed on the surface of cancer cells, this signaling protein helps them proliferate uncontrollably and is linked with a poor prognosis. Now, researchers have developed a DNA nanorobot...
A drop of stem cells restores mice’s sense of smell
10.6.2019 | Press monitoring
A team of researchers has restored the sense of smell in a group of mice by grafting stem cells into the rodents’ noses according to new results published in Stem Cell Reports. The stem cells, which are known as “globose basal cells,” are precursors to fully developed olfactory neurons. Once implanted into mice through a simple “nose drop...

Nanotechnology treatment shows promise against multiple sclerosis
7.6.2019 | Press monitoring
A nanotechnology treatment derived from bone marrow stem cells has reversed multiple sclerosis symptoms in mice and could eventually be used to help humans, according to a new study led by University of California, Irvine researchers. In past experiments, intravenously injected stem cells – taken from bone marrow and activated with interferon...

Harvard breakthrough shows stem cells can be genetically edited in the body
5.6.2019 | Press monitoring
We owe our long lives to stem cells, which are nestled deep inside certain tissues in the body and constantly replace old cells. In recent years scientists have been able to correct genetic diseases by removing these stem cells, editing their genomes and then implanting them back into the patient, but that adds complications. Now, new research led...

Nordic microalgae cleans wastewater and produces biodiesel
3.6.2019 | Press monitoring
Green microalgae are photosynthetic water organisms that use sunlight and a few other nutrients to transform CO2 into energy and biomass. Algae biomass is considered a good raw material for the production of biofuels, as these microorganisms can naturally form and store large amounts of lipids, which in turn can be converted into biodiesel. In...

Chemists develop nanoscale bioabsorbable wound dressing
31.5.2019 | Press monitoring
Scientists at Texas A&M University are harnessing the combined power of organic nanomaterials-based chemistry and a natural product found in crustacean exoskeletons to help bring emergency medicine one step closer to a viable solution for mitigating blood loss, from the hospital to the battlefield. Hemorrhage is a leading cause of death in...

Cranberries join forces with antibiotics to fight bacteria
29.5.2019 | Press monitoring
The global spread of antibiotic resistance is undermining decades of progress in fighting bacterial infections. Due to the overuse of antibiotics in medicine and agriculture, we are on the cusp of returning to a pre-antibiotic era in which minor infections can once again become deadly. Therefore, countering the fall in antibiotic efficacy by...
