biologisk ur fundet i noget af det ældste liv – cyanobakterier

[Research Article] Structural basis of the day-night transition in a bacterial circadian clockCircadian clocks are ubiquitous timing systems that induce rhythms of biological activities in synchrony with night and day. In cyanobacteria, timing is generated by a posttranslational clock consisting of KaiA, KaiB, and KaiC proteins and a set of output signaling proteins, SasA and CikA, which transduce this rhythm to control gene expression. Here, we describe crystal and nuclear magnetic resona

Structures of the cyanobacterial circadian oscillator frozen in a fully assembled stateCyanobacteria have a robust circadian oscillator, known as the Kai system. Reconstituted from the purified protein components KaiC, KaiB, and KaiA, it can tick autonomously in the presence of adenosine 5'-triphosphate (ATP). The KaiC hexamers enter a natural 24-hour reaction cycle of autophosphorylation and assembly with KaiB and KaiA in numerous diverse forms. We describe the preparation of stoic

The well-validated role of mutationally activated RAS genes in driving cancer development and growth has stimulated comprehensive efforts to develop therapeutic strategies to block mutant RAS function for cancer treatment. Disappointingly, despite more than three decades of research effort, clinically effectiv

[Special Issue Review] Waste disposal—An attractive strategy for cancer therapyTargeted therapies for cancer are typically small molecules or monoclonal antibodies that act by inhibiting the activity of specific proteins that drive tumor growth. Although many of these drugs are effective in cancer patients, the response is often not durable because tumor cells develop resistance to the drugs. Another limitation of this strategy is that not all oncogenic driver proteins are "

Aggregation of the Whi3 protein, not loss of heterochromatin, causes sterility in old yeast cellsIn yeast, heterochromatin silencing is reported to decline in aging mother cells, causing sterility in old cells. This process is thought to reflect a decrease in the activity of the NAD+ (oxidized nicotinamide adenine dinucleotide)–dependent deacetylase Sir2. We tested whether Sir2 becomes nonfunctional gradually or precipitously during aging. Unexpectedly, silencing of the heterochromatic HML an

Revealing the subfemtosecond dynamics of orbital angular momentum in nanoplasmonic vorticesThe ability of light to carry and deliver orbital angular momentum (OAM) in the form of optical vortices has attracted much interest. The physical properties of light with a helical wavefront can be confined onto two-dimensional surfaces with subwavelength dimensions in the form of plasmonic vortices, opening avenues for thus far unknown light-matter interactions. Because of their extreme rotation

Quantized thermal transport in single-atom junctionsThermal transport in individual atomic junctions and chains is of great fundamental interest because of the distinctive quantum effects expected to arise in them. By using novel, custom-fabricated, picowatt-resolution calorimetric scanning probes, we measured the thermal conductance of gold and platinum metallic wires down to single-atom junctions. Our work reveals that the thermal conductance of

Direct observation of individual hydrogen atoms at trapping sites in a ferritic steelThe design of atomic-scale microstructural traps to limit the diffusion of hydrogen is one key strategy in the development of hydrogen-embrittlement–resistant materials. In the case of bearing steels, an effective trapping mechanism may be the incorporation of finely dispersed V-Mo-Nb carbides in a ferrite matrix. First, we charged a ferritic steel with deuterium by means of electrolytic loading t

Building Archean cratons from Hadean mafic crustGeologic processing of Earth's surface has removed most of the evidence concerning the nature of Earth's first crust. One region of ancient crust is the Hudson Bay terrane of northeastern Canada, which is mainly composed of Neoarchean felsic crust and forms the nucleus of the Northeastern Superior Province. New data show these ~2.7-billion-year-old rocks to be the youngest to yield variability in

FUTURITY Cells don't 'talk' as well if they're scrunched together Collective cell movement, such as metastasizing cancer cells or wound healing, requires coordinated actions.

Pattern of mammal dwarfing during global warmingMore than 50 million years ago, when the Earth experienced a series of extreme global warming events, early mammals responded by shrinking in size. While this mammalian dwarfism has previously been linked to the largest of these events, new research has found that this evolutionary process can happen in smaller, so-called hyperthermals, indicating an important pattern that could help shape an unde

Outwitting climate change with a plant 'dimmer'?Plants possess molecular mechanisms that prevent them from blooming in winter. Once the cold of winter has passed, they are deactivated. However, if it is still too cold in spring, plants adapt their blooming behavior accordingly. Scientists have discovered genetic changes for this adaptive behavior. In light of the temperature changes resulting from climate change, this may come in useful for sec

BioNyt Videnskabens Verden ( 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.
