アディポネクチン受容体の構造に関する知見から、こうしたタンパク質には、その配位子であるアディポネクチンホルモンによるシグナル伝達能力をもたらす固有の酵素活性があることを示す証拠が得られた。

一般的には、材料の電荷担体の符号は「ホール電圧」の符号に反映される。しかし今回、鎖かたびらに着想を得て作製された三次元構造体で、電荷担体を変えなくても、構造を変えるとホール電圧が逆転することが明らかになった。

ラムノガラクツロナンIIと呼ばれる多糖類は一部の果実の主成分であるが、ヒトはその消化を腸内微生物相に依存している。ラムノガラクツロナンIIの消化に関与する微生物と過程が今回明らかになった。

If neutrinos are their own antiparticles, neutrinoless double-β decay of 76Ge should occur; a new lower-limit half-life of 5 × 1025 years for this process has now been determined under background-free conditions.

During emergency myelopoiesis in mice, clusters of self-renewing granulocyte/macrophage progenitors (GMP) are transiently formed in the bone marrow cavity to produce a burst of myeloid cells; in leukaemia, GMP clusters persist and constantly generate myeloid leukaemia cells.

A chromosome conformation capture method in which single cells are first imaged and then processed enables intact genome folding to be studied at a scale of 100 kb, validated, and analysed to generate hypotheses about 3D genomic interactions and organisation.

The hierarchical deconstruction of the complex pectic glycan rhamnogalacturonan-II by the human gut bacterium Bacteroides thetaiotaomicron reveals seven new families of glycoside hydrolases and three catalytic functions not previously observed.

A massive ancient galaxy with minimal star formation is observed spectroscopically at an epoch when the Universe is less than 2 billion years old, posing a challenge to theories.

By switching shell growth on and off on the (0001) facet of wurtzite CdSe cores to produce a built-in biaxial strain that lowers the optical gain threshold, we achieve continuous-wave lasing in colloidal quantum dot films.

As an alternative vehicle fuel, hydrogen can be generated in situ from methanol and water—a process that is shown here to occur under mild conditions using a catalyst that comprises platinum atomically dispersed on an α-molybdenum carbide substrate.

Long-term records of global carbonyl sulfide levels reveal that terrestrial gross primary production (GPP) increased by around 30% during the twentieth century—a finding that may aid understanding of the connection between GPP growth and climate change.

Whereas the enteric nervous system of jawed vertebrates is derived largely from the vagal neural crest, that of the sea lamprey (Petromyzon marinus) is populated by trunk-derived neural crest cells that may be homologous to Schwann cell precursors.

In addition to generating lift by leading-edge vortices (as used by most insects), mosquitoes also employ trailing-edge vortices and a lift mechanism from wing rotation, which enables them to stay airborne despite having a seemingly unlikely airframe.

A sizable fraction of granule cells convey information about the expectation of reward, with different populations responding to reward delivery, anticipation and omission, with some responses evolving over time with learning.

In the absence of DHX9, circular RNAs accumulate and transcription and translation are dysregulated—effects that are exacerbated by concomitant depletion of the RNA-editing enzyme ADAR.
