酵素はきっちり決められた反応によって大気中の二酸化炭素と結合するが、合成材料は二酸化炭素を受動的に吸着するだけであると思われている。だが、金属有機構造体と呼ばれる化合物の研究によって、これが必ずしも正しくないことが示された。

陸上生物圏の炭素シンクは過去30年の間に、人間活動によって作り出された二酸化炭素の多くを取り込んで拡大してきた。このような拡大傾向の頭打ちを示す最初の兆候が、アマゾン熱帯森林で見つかった。

Extensive genetic analysis of over 2,000 individuals from different locations in Britain reveals striking fine-scale patterns of population structure; comparisons with similar genetic data from the European continent reveal the legacy of earlier population migrations and information about the ancestry of current populations in specific geographic regions.

dG•dT and rG•rU ‘wobble’ mispairs in DNA and RNA transiently form base pairs with Watson–Crick geometry via tautomerization and ionization with probabilities that correlate with misincorporation probabilities during replication and translation.

The crystal structure of the heterohexameric origin recognition complex (ORC), essential for coordinating DNA replication onset in eukaryotes, is resolved at 3.5 Å resolution.

Far-infrared measurements of galaxies in the early Universe would reveal their detailed properties, but have been lacking for the more typical galaxies where most stars form; here an archetypal, early Universe star-forming galaxy is detected at far-infrared wavelengths, allowing its dust mass, total star-formation rate and dust-to-gas ratio to be calculated.

Detection of carbon monoxide in a molecular cloud in dwarf galaxy NGC 5253 reveals the highest star-formation efficiency yet seen, driven by an accreting streamer of gas.

Empirical evidence for the effect of rising atmospheric carbon dioxide levels on Earth’s surface energy balance is presented: the increase in surface radiative forcing from 2000 to 2010 measured at two sites is directly attributable to the increase in atmospheric carbon dioxide over that decade and agrees with model results.

The capacity of Amazonian forests to sequester carbon has weakened with potentially important implications for climate change.

In vitro evolution experiments on haploid, diploid, and tetraploid yeast strains show that adaptation is faster in tetraploids, providing direct quantitative evidence that in some environments polyploidy can accelerate evolutionary adaptation.

The mechanisms of thermosensing in the Drosophila brain are elucidated by the identification of distinct classes of projection neurons which are excited either by external cooling or warming, or both; the neurons that are excited by warming participate in complex circuits that incorporate crossover inhibition from cool receptor neurons.

This study identifies distinct classes of neurons in the fly brain, which respond to external cooling, warming, or both, and contribute to behavioural response; the results illustrate how higher brain centres extract a stimulus’ quality, intensity and timing from a simple temperature map at the periphery.

The structure and function of CetZ, a protein related to both tubulin and FtsZ (the bacterial homologue of tubulin) from the archaeon Haloferax volcano, is reported and its involvement in the control of cell shape uncovered; it appears that this family of proteins was involved in the control of cell shape long before the evolution of eukaryotes.

A clinical trial in patients with glioblastoma shows increased immune and anti-tumour responses to dendritic cell vaccination after pre-conditioning the site of vaccination with tetanus toxoid (Td); similar results are also seen in mice in part due to the actions of the chemokine CCL3, and the findings may represent new ways to improve the efficacy of anti-cancer vaccines.

A newly developed method, NAD captureSeq, has been used to show that bacteria cap the 5′-ends of some RNAs to protect against degradation, much as happens with eukaryotic messenger RNAs, although with a different modification: nicotinamide adenine dinucleotide.
