Scientists stitch up photosynthetic megacomplex

Scientists report on a new technique that allowed them to extract a photosynthetic megacomplex consisting of light antenna and two reaction centers from the membrane of a cynaobacterium. This is the first time an entire complex has been isolated and studied as a functioning whole.

Releasing the untapped biotechnology potential of the sea

While marine microorganisms have long been identified as an untapped resource of biotechnological potential, their exploitation has been hampered by the difficulty and expense of isolating their valuable novel chemicals and molecules. This is a wasted opportunity, and is something that the MaCuMBA project aims to rectify.

Researchers uncover mechanism behind blood stem cells' longevity

Researchers have long wondered what allows blood stem cells to persist for decades, when their progeny last for days, weeks or months before they need to be replaced. Now, a study from the University of Pennsylvania has uncovered one of the mechanisms that allow these stem cells to keep dividing in perpetuity.

Implantable slimming aid

Biotechnologists have constructed a genetic regulatory circuit from human components that monitors blood-fat levels. In response to excessive levels, it produces a messenger substance that signalizes satiety to the body. Tests on obese mice reveal that this helps them to lose weight.

Tidy knots are faster - Viruses are as simple as they are 'smart'

Viruses are as simple as they are 'smart': too elementary to be able to reproduce by themselves, they exploit the reproductive machinery of cells, by inserting pieces of their own DNA so that it is transcribed by the host cell. To do this, they first have to inject their own genetic material into the cells they infect. Researchers have studied how this occurs and how long it takes for this process to be completed.

Scientists capture 'redox moments' in living cells

Scientists have glimpsed key chemical events, known as redox reactions, inside living cells of fast-growing Synechococcus. The work marks the first time that redox activity, a very fast regulatory network involved in all major aspects of a cell's operation, has been observed in specific proteins within living cells. The findings hone scientists' control over a common tool in the biofuels toolbox - a microbe that supplies some of the oxygen you breathe.

How 'quality control' functions in ribosome assembly

Like automobiles, ribosomes must pass through 'quality control' after their many components are assembled. Scientists investigated an important component in this control process. The researchers demonstrated that a specific protein, which occurs in all cells from yeast to humans, works like a molecular control switch and prevents incomplete ribosomes from leaving the 'assembly hall'.

New findings on spider silk

Spider silk fibers are very light, extremely tough and highly stretchable. This makes them interest-ing for industrial applications. Researchers at the Biocenter of the University of Würzburg have now discovered new details about the proteins of which spider silk consists.
