The finding of a ‘cell-like’ structure, which investigators now know once held water, came about as a result of collaboration between scientists in the UK and…

The present invention describes a novel 3D-bioprinting process for the production of a three-dimensional, biomimetic tumour angiogenesis model (3D-TAM). In a first step, a supply channel covered by an endothelial cell layer is generated using the 3D-bioprinting process and in a second step, tumour cells are embedded into a surrounding hydrogel-matrix cell-suspension. Then, angiogenesis will start from the supply channel towards the tumour cells (which release angiogenic factors) leading to a vascularized and perfusable tumour.

The heterologous expression of genes in prokaryotes can be challenging, especially if the genes originate from a distant host or if the source is uncertain, such as a metagenomic expression library. Many vectors have been developed based on broad host range origins of replication, but these tend to focus on either gram(+) or gram(-) prokaryotes. This invention regards the construction of a completely synthetic expression vector, namely pPolyREPII, based on both the pBBR1 and pWV01 origin of replication.

Scientists of the University of Muenster succeeded in turning a stress susceptible tobacco variety (Xanthi) into an exceptionally stress-tolerant plant using replacement of glucose-6-phosphate dehydrogenase (G6PDH), the rate-limiting step of the oxidative pentose-phos¬phate pathway (OPPP) in the cytosol by a specially suited plastidic isoform.
The G6PDH isoenzyme-replacement technology is a promising tool to improve not only stress tolerance in general, but also biomass production, seed quality and energy density of agronomically important plants.

Scientists can now explain a third of the inherited risk of prostate cancer, after a major international study identified 23 new genetic variants associated…

The researchers carefully simulated the atmospheric chemistry of alien worlds devoid of life thousands of times over a period of more than four years, varying…
