<title>Biomechanics: Robotic whiskers used to sense features</title>
<link>http://dx.doi.org/10.1038/443525a</link>
<description>Whiskers mimicking those of seals or rats might be useful for underwater tracking or tactile exploration.Several species of terrestrial and marine mammals with whiskers (vibrissae) use them to sense and navigate in their environment &#8212; for example, rats use their whiskers to discern the features of objects, and seals rely on theirs to track the hydrodynamic trails of their prey. Here we show that the bending moment &#8212; sometimes referred to as torque &#8212; at the whisker base can be used to generate three-dimensional spatial representations of the environment, and we use this principle to construct robotic whisker arrays that extract precise information about object shape and fluid flow. Our results will contribute to the development of versatile tactile-sensing systems for robotic applications, and demonstrate the value of hardware models in understanding how sensing mechanisms and movement control strategies are interlocked.</description>

<description>Arising from: P. Puigserver et al. Nature423, 550&#8211;555 (2003).Increased expression of the gene encoding the enzyme glucose-6-phosphatase (G6Pase) contributes to the increased production of glucose by the liver that occurs in individuals with diabetes. Puigserver et al. show that the transcription factor FOXO1 and the transcriptional co-activator PGC-1&#945; act synergistically to stimulate the expression of genes in the gluconeogenesis pathway and propose that PGC-1&#945; acts, in part, directly through FOXO1. Here we show that FOXO1 is neither required nor sufficient for the stimulation of G6Pase&#8211;luciferase fusion gene expression by PGC-1&#945;. Our results indicate that the transcriptional interaction between FOXO1 and PGC-1&#945; is indirect.</description>

<title>Electron acceleration from contracting magnetic islands during reconnection</title>
<link>http://dx.doi.org/10.1038/nature05116</link>
<description>A long-standing problem in the study of space and astrophysical plasmas is to explain the production of energetic electrons as magnetic fields &#8216;reconnect&#8217; and release energy. In the Earth's magnetosphere, electron energies reach hundreds of thousands of electron volts (refs 1&#8211;3), whereas the typical electron energies associated with large-scale reconnection-driven flows are just a few electron volts. Recent observations further suggest that these energetic particles are produced in the region where the magnetic field reconnects. In solar flares, upwards of 50 per cent of the energy released can appear as energetic electrons. Here we show that electrons gain kinetic energy by reflecting from the ends of the contracting &#8216;magnetic islands&#8217; that form as reconnection proceeds. The mechanism is analogous to the increase of energy of a ball reflecting between two converging walls&#8212;the ball gains energy with each bounce. The repetitive interaction of electrons with many islands allows large numbers to be efficiently accelerated to high energy. The back pressure of the energetic electrons throttles reconnection so that the electron energy gain is a large fraction of the released magnetic energy. The resultant energy spectra of electrons take the form of power laws with spectral indices that match the magnetospheric observations.</description>

<title>Quantum teleportation between light and matter</title>
<link>http://dx.doi.org/10.1038/nature05136</link>
<description>Quantum teleportation is an important ingredient in distributed quantum networks, and can also serve as an elementary operation in quantum computers. Teleportation was first demonstrated as a transfer of a quantum state of light onto another light beam; later developments used optical relays and demonstrated entanglement swapping for continuous variables. The teleportation of a quantum state between two single material particles (trapped ions) has now also been achieved. Here we demonstrate teleportation between objects of a different nature&#8212;light and matter, which respectively represent &#8216;flying&#8217; and &#8216;stationary&#8217; media. A quantum state encoded in a light pulse is teleported onto a macroscopic object (an atomic ensemble containing 10 caesium atoms). Deterministic teleportation is achieved for sets of coherent states with mean photon number (n) up to a few hundred. The fidelities are 0.58 &#177; 0.02 for n &#61; 20 and 0.60 &#177; 0.02 for n &#61; 5&#8212;higher than any classical state transfer can possibly achieve. Besides being of fundamental interest, teleportation using a macroscopic atomic ensemble is relevant for the practical implementation of a quantum repeater. An important factor for the implementation of quantum networks is the teleportation distance between transmitter and receiver; this is 0.5&#8201;metres in the present experiment. As our experiment uses propagating light to achieve the entanglement of light and atoms required for teleportation, the present approach should be scalable to longer distances.</description>

<title>Rapid subtropical North Atlantic salinity oscillations across Dansgaard&#8211;Oeschger cycles</title>

<link>http://dx.doi.org/10.1038/nature05121</link>
<description>Geochemical and sedimentological evidence suggest that the rapid climate warming oscillations of the last ice age, the Dansgaard&#8211;Oeschger cycles, were coupled to fluctuations in North Atlantic meridional overturning circulation through its regulation of poleward heat flux. The balance between cold meltwater from the north and warm, salty subtropical gyre waters from the south influenced the strength and location of North Atlantic overturning circulation during this period of highly variable climate. Here we investigate how rapid reorganizations of the ocean&#8211;atmosphere system across these cycles are linked to salinity changes in the subtropical North Atlantic gyre. We combine Mg/Ca palaeothermometry and oxygen isotope ratio measurements on planktonic foraminifera across four Dansgaard&#8211;Oeschger cycles (spanning 45.9&#8211;59.2&#8201;kyr ago) to generate a seawater salinity proxy record from a subtropical gyre deep-sea sediment core. We show that North Atlantic gyre surface salinities oscillated rapidly between saltier stadial conditions and fresher interstadials, covarying with inferred shifts in the Tropical Atlantic hydrologic cycle and North Atlantic overturning circulation. These salinity oscillations suggest a reduction in precipitation into the North Atlantic and/or reduced export of deep salty thermohaline waters during stadials. We hypothesize that increased stadial salinities preconditioned the North Atlantic Ocean for a rapid return to deep overturning circulation and high-latitude warming by contributing to increased North Atlantic surface-water density on interstadial transitions.</description>

<title>Lithium isotope evidence for subduction-enriched mantle in the source of mid-ocean-ridge basalts</title>
<link>http://dx.doi.org/10.1038/nature05144</link>
<description>&#8216;Recycled&#8217; crustal materials, returned from the Earth's surface to the mantle by subduction, have long been invoked to explain compositional heterogeneity in the upper mantle. Yet increasingly, problems have been noted with this model. The debate can be definitively addressed using stable isotope ratios, which should only significantly vary in primitive, mantle-derived materials as a consequence of recycling. Here we present data showing a notable range in lithium isotope ratios in basalts from the East Pacific Rise, which correlate with traditional indices of mantle heterogeneity (for example, 143Nd/144Nd ratios). Such co-variations of stable and radiogenic isotopes in melts from a normal ridge segment provide critical evidence for the importance of recycled material in generating chemical heterogeneity in the upper mantle. Contrary to many models, however, the elevated lithium isotope ratios of the &#8216;enriched&#8217; East Pacific Rise lavas imply that subducted ocean crust is not the agent of enrichment. Instead, we suggest that fluid-modified mantle, which is enriched during residency in a subduction zone, is mixed back into the upper mantle to cause compositional variability.</description>

<title>Reassembly of shattered chromosomes in Deinococcus radiodurans</title>
<link>http://dx.doi.org/10.1038/nature05160</link>
<description>Dehydration or desiccation is one of the most frequent and severe challenges to living cells. The bacterium Deinococcus radiodurans is the best known extremophile among the few organisms that can survive extremely high exposures to desiccation and ionizing radiation, which shatter its genome into hundreds of short DNA fragments. Remarkably, these fragments are readily reassembled into a functional 3.28-megabase genome. Here we describe the relevant two-stage DNA repair process, which involves a previously unknown molecular mechanism for fragment reassembly called &#8216;extended synthesis-dependent strand annealing&#8217; (ESDSA), followed and completed by crossovers. At least two genome copies and random DNA breakage are requirements for effective ESDSA. In ESDSA, chromosomal fragments with overlapping homologies are used both as primers and as templates for massive synthesis of complementary single strands, as occurs in a single-round multiplex polymerase chain reaction. This synthesis depends on DNA polymerase I and incorporates more nucleotides than does normal replication in intact cells. Newly synthesized complementary single-stranded extensions become &#8216;sticky ends&#8217; that anneal with high precision, joining together contiguous DNA fragments into long, linear, double-stranded intermediates. These intermediates require RecA-dependent crossovers to mature into circular chromosomes that comprise double-stranded patchworks of numerous DNA blocks synthesized before radiation, connected by DNA blocks synthesized after radiation.</description>

<title>Functional epistasis on a common MHC haplotype associated with multiple sclerosis</title>
<link>http://dx.doi.org/10.1038/nature05133</link>
<description>Genes in the major histocompatibility complex (MHC) encode proteins important in activating antigen-specific immune responses. Alleles at adjacent MHC loci are often in strong linkage disequilibrium; however, little is known about the mechanisms responsible for this linkage disequilibrium. Here we report that the human MHC HLA-DR2 haplotype, which predisposes to multiple sclerosis, shows more extensive linkage disequilibrium than other common caucasian HLA haplotypes in the DR region and thus seems likely to have been maintained through positive selection. Characterization of two multiple-sclerosis-associated HLA-DR alleles at separate loci by a functional assay in humanized mice indicates that the linkage disequilibrium between the two alleles may be due to a functional epistatic interaction, whereby one allele modifies the T-cell response activated by the second allele through activation-induced cell death. This functional epistasis is associated with a milder form of multiple-sclerosis-like disease. Such epistatic interaction might prove to be an important general mechanism for modifying exuberant immune responses that are deleterious to the host and could also help to explain the strong linkage disequilibrium in this and perhaps other HLA haplotypes.</description>

<title>Genomic analysis of increased host immune and cell death responses induced by 1918 influenza virus</title>
<link>http://dx.doi.org/10.1038/nature05181</link>

<description>The influenza pandemic of 1918&#8211;19 was responsible for about 50 million deaths worldwide. Modern histopathological analysis of autopsy samples from human influenza cases from 1918 revealed significant damage to the lungs with acute, focal bronchitis and alveolitis associated with massive pulmonary oedema, haemorrhage and rapid destruction of the respiratory epithelium. The contribution of the host immune response leading to this severe pathology remains largely unknown. Here we show, in a comprehensive analysis of the global host response induced by the 1918 influenza virus, that mice infected with the reconstructed 1918 influenza virus displayed an increased and accelerated activation of host immune response genes associated with severe pulmonary pathology. We found that mice infected with a virus containing all eight genes from the pandemic virus showed marked activation of pro-inflammatory and cell-death pathways by 24&#8201;h after infection that remained unabated until death on day 5. This was in contrast with smaller host immune responses as measured at the genomic level, accompanied by less severe disease pathology and delays in death in mice infected with influenza viruses containing only subsets of 1918 genes. The results indicate a cooperative interaction between the 1918 influenza genes and show that study of the virulence of the 1918 influenza virus requires the use of the fully reconstructed virus. With recent concerns about the introduction of highly pathogenic avian influenza viruses into humans and their potential to cause a worldwide pandemic with disastrous health and economic consequences, a comprehensive understanding of the global host response to the 1918 virus is crucial. Moreover, understanding the contribution of host immune responses to virulent influenza virus infections is an important starting point for the identification of prognostic indicators and the development of novel antiviral therapies.</description>

<title>Sodium-dependent uptake of inorganic phosphate by the intracellular malaria parasite</title>
<link>http://dx.doi.org/10.1038/nature05149</link>
<description>As the malaria parasite, Plasmodium falciparum, grows within its host erythrocyte it induces an increase in the permeability of the erythrocyte membrane to a range of low-molecular-mass solutes, including Na&#43; and K&#43; (ref. 1). This results in a progressive increase in the concentration of Na&#43; in the erythrocyte cytosol. The parasite cytosol has a relatively low Na&#43; concentration and there is therefore a large inward Na&#43; gradient across the parasite plasma membrane. Here we show that the parasite exploits the Na&#43; electrochemical gradient to energize the uptake of inorganic phosphate (Pi), an essential nutrient. Pi was taken up into the intracellular parasite by a Na&#43;-dependent transporter, with a stoichiometry of 2Na&#43;:1Pi and with an apparent preference for the monovalent over the divalent form of Pi. A Pi transporter (PfPiT) belonging to the PiT family was cloned from the parasite and localized to the parasite surface. Expression of PfPiT in Xenopus oocytes resulted in Na&#43;-dependent Pi uptake with characteristics similar to those observed for Pi uptake in the parasite. This study provides new insight into the significance of the malaria-parasite-induced alteration of the ionic composition of its host cell.</description>

<title>Identification of a mammalian mitochondrial porphyrin transporter</title>
<link>http://dx.doi.org/10.1038/nature05125</link>

<description>The movement of anionic porphyrins (for example, haem) across intracellular membranes is crucial to many biological processes, but their mitochondrial translocation and coordination with haem biosynthesis is not understood. Transport of porphyrins into isolated mitochondria is energy-dependent, as expected for the movement of anions into a negatively charged environment. ATP-binding cassette transporters actively facilitate the transmembrane movement of substances. We found that the mitochondrial ATP-binding cassette transporter ABCB6 is upregulated (messenger RNA and protein in human and mouse cells) by elevation of cellular porphyrins and postulated that ABCB6 has a function in porphyrin transport. We also predicted that ABCB6 is functionally linked to haem biosynthesis, because its mRNA is found in both human bone marrow and CD71&#43; early erythroid cells (by database searching), and because our results show that ABCB6 is highly expressed in human fetal liver, and Abcb6 in mouse embryonic liver. Here we demonstrate that ABCB6 is uniquely located in the outer mitochondrial membrane and is required for mitochondrial porphyrin uptake. After ABCB6 is upregulated in response to increased intracellular porphyrin, mitochondrial porphyrin uptake activates de novo porphyrin biosynthesis. This process is blocked when the Abcb6 gene is silenced. Our results challenge previous assumptions about the intracellular movement of porphyrins and the factors controlling haem biosynthesis.</description>

<title>Molecular architecture and assembly of the DDB1&#8211;CUL4A ubiquitin ligase machinery</title>
<link>http://dx.doi.org/10.1038/nature05175</link>

<description>Protein ubiquitination is a common form of post-translational modification that regulates a broad spectrum of protein substrates in diverse cellular pathways. Through a three-enzyme (E1&#8211;E2&#8211;E3) cascade, the attachment of ubiquitin to proteins is catalysed by the E3 ubiquitin ligase, which is best represented by the superfamily of the cullin-RING complexes. Conserved from yeast to human, the DDB1&#8211;CUL4&#8211;ROC1 complex is a recently identified cullin-RING ubiquitin ligase, which regulates DNA repair, DNA replication and transcription, and can also be subverted by pathogenic viruses to benefit viral infection. Lacking a canonical SKP1-like cullin adaptor and a defined substrate recruitment module, how the DDB1&#8211;CUL4&#8211;ROC1 E3 apparatus is assembled for ubiquitinating various substrates remains unclear. Here we present crystallographic analyses of the virally hijacked form of the human DDB1&#8211;CUL4A&#8211;ROC1 machinery, which show that DDB1 uses one &#946;-propeller domain for cullin scaffold binding and a variably attached separate double-&#946;-propeller fold for substrate presentation. Through tandem-affinity purification of human DDB1 and CUL4A complexes followed by mass spectrometry analysis, we then identify a novel family of WD40-repeat proteins, which directly bind to the double-propeller fold of DDB1 and serve as the substrate-recruiting module of the E3. Together, our structural and proteomic results reveal the structural mechanisms and molecular logic underlying the assembly and versatility of a new family of cullin-RING E3 complexes.</description>

<title>Co-evolution of transcriptional and post-translational cell-cycle regulation</title>
<link>http://dx.doi.org/10.1038/nature05186</link>
<description>DNA microarray studies have shown that hundreds of genes are transcribed periodically during the mitotic cell cycle of humans, budding yeast, fission yeast and the plant Arabidopsis thaliana. Here we show that despite the fact the protein complexes involved in this process are largely the same among all eukaryotes, their regulation has evolved considerably. Our comparative analysis of several large-scale data sets reveals that although the regulated subunits of each protein complex are expressed just before its time of action, the identity of the periodically expressed proteins differs significantly between organisms.  Moreover, we show that these changes in transcriptional regulation have co-evolved with post-translational control independently in several lineages; loss or gain of cell-cycle-regulated transcription of specific genes is often mirrored by changes in phosphorylation of the proteins that they encode. Our results indicate that many different solutions have evolved for assembling the same molecular machines at the right time during the cell cycle, involving both transcriptional and post-translational layers that jointly control the dynamics of biological systems.</description>
