N6-メチルアデニンと呼ばれる修飾型のアデニン塩基がマウスDNA中で見つかった。これは、哺乳類が持つ修飾型塩基はシトシン誘導体だけであるとする説を突き崩す結果である。

Bone marrow endothelial cells have dual roles in the regulation of haematopoietic stem cell maintenance and in the trafficking of blood cells between the bone marrow and the blood circulatory system; this study shows that these different functions are regulated by distinct types of endothelial blood vessels with different permeability properties, affecting the metabolic state of their neighbouring stem cells.

The prevalence of N6-adenine DNA methylation in mammals was previously unknown; this study reveals that N6-methyladenine can be found in mouse embryonic stem cells, especially at subfamilies of young (<1.5 million years old) LINE-1 transposons.

X-ray crystal structures of the human serotonin transporter (SERT) bound to the antidepressants (S)-citalopram or paroxetine show that the antidepressants lock the protein in an outward-open conformation, and directly block serotonin from entering its binding site; the structures define the mechanism of antidepressant action in SERT and pave the way for future drug design.

The galaxy NGC 1600 is found to contain an enormous black hole of 17 billion solar masses—the first black hole of such a size to be found in an environment outside the richest clusters of galaxies.

Scanned Josephson tunnelling microscopy is used to image Cooper pair tunnelling from a superconducting microscope tip to the quantum condensate of Bi2Sr2CaCu2O8+x, thus revealing the spatially modulated density of Cooper pairs predicted from several theories of the cuprate pseudogap phase.

For adsorption processes, gas uptake usually increases with increasing pressure; however, here the phenomenon of negative gas adsorption is demonstrated in a metal–organic framework, which undergoes a sudden hysteretic structural deformation and pore contraction, releasing guest molecules.

Here, a method is described by which to generate all possible stereoisomers of certain amino alcohols—a protocol that should see use in drug discovery and development, where it is important to determine the differing effects of stereoisomeric drug candidates.

Population-weighted analysis of US weather conditions shows that the nation’s weather has generally become more pleasant since 1974, possibly explaining the lack of broad public support for action on climate change; projections of future US weather indicate that conditions will probably worsen.

A tremor source on the San Andreas Fault produced an unusual sequence of low-frequency earthquakes until it was disrupted by the 2004 Parkfield earthquake; the peculiar recurrence pattern has now been modelled, showing that such slip behaviour occurs when the tremor asperity size is close to the critical nucleation size of earthquakes.

New excavations in Liang Bua, where the remains of the ‘Hobbit’ (Homo floresiensis) were discovered, show that this diminutive human species used this cave between 190,000 and 50,000 years ago, and not until as recently as 12,000 years ago as previously interpreted; modern humans have been present in Australia since around 50,000 years ago, so whether Homo floresiensis survived long enough to witness the arrival of modern humans is still an open question.

Two-photon calcium imaging and electron microscopy were used to explore the relationship between structure and function in mouse primary visual cortex, showing that layer 2/3 neurons are connected in subnetworks, that pyramidal neurons with similar orientation selectivity preferentially form synapses with each other, and that neurons with similar orientation tuning form larger synapses; this study exemplifies functional connectomics as a powerful method for studying the organizational logic of cortical networks.

Circadian rhythms in the intracellular concentration of magnesium ions act as a cell-autonomous timekeeping component to determine key clock properties and tune cellular metabolism both in a human cell line and in a unicellular alga.

The proteasome-associated enzyme USP14 regulates protein degradation by removing ubiquitin from proteins; here it is shown that USP14 removes ubiquitin chains from in vitro generated cyclin B conjugates en bloc and within milliseconds, before the proteasome has a chance to initiate degradation, and proceeds until a single chain remains.
