SCAN1-TDP1 trapping on mitochondrial DNA promotes mitochondrial dysfunction and mitophagy

A homozygous mutation of human tyrosyl-DNA phosphodiesterase 1 (TDP1) causes the neurodegenerative syndrome, spinocerebellar ataxia with axonal neuropathy (SCAN1).

Nanoparticles and nanoclusters called "superballs" offer more control to optogenetics, which uses light to control cells within living tissue. The biological technique controls cells in tissues that have been genetically modified for light sensitivity. Drawbacks are that the light can activate several genes at once, and that it must penetrate deeply in order to have an effect. The new nanoparticl

Dusty star-forming galaxy MAMBO-9 investigated in detail

Using the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has conducted detailed observations of the dusty star-forming galaxy MMJ100026.36+021527.9, better known as MAMBO-9. The study, described in a paper published October 29 on arXiv.org, provides physical characterization of this galaxy, shedding more light on its nature.

BioNyt Videnskabens Verden (www.bionyt.dk) er Danmarks ældste populærvidenskabelige tidsskrift for naturvidenskab. Det er det eneste blad af sin art i Danmark, som er helliget international forskning inden for livsvidenskaberne.

Bladet bringer aktuelle, spændende forskningsnyheder inden for biologi, medicin og andre naturvidenskabelige områder som f.eks. klimaændringer, nanoteknologi, partikelfysik, astronomi, seksualitet, biologiske våben, ecstasy, evolutionsbiologi, kloning, fedme, søvnforskning, muligheden for liv på mars, influenzaepidemier, livets opståen osv.

Artiklerne roses for at gøre vanskeligt stof forståeligt, uden at den videnskabelige holdbarhed tabes.
