We've seen off smallpox, polio and measles – so why does a truly reliable flu jab still elude us? By Jeremy Brown Vaccines are one of the great success stories of modern medicine. Because of them we are no longer vulnerable to smallpox or polio or measles. The flu vaccine, however, is a different story. Its effectiveness varies from patient to patient, from population to population, and from year
NARVA, Estonia—If you haven't heard of Narva, you might very soon. This small, mostly Russian-speaking city lies along Estonia's boundary with Russia, separated geographically from its larger neighbor only by a partially frozen river. A 13th-century castle towers over passersby, while an intimidating medieval stronghold stares back across the river from the Russian side. A short walk away stands
There is little to no evidence that two surgical procedures used to fuse crumbled vertebrae following a spinal fracture caused by osteoporosis reduce pain for patients any better than non-surgical or placebo procedures, according to a new report from a global task force of bone health experts published today in the Journal of Bone and Mineral Research (JBMR).
By studying the phenomenon of contagious yawning, the researchers learned that people's reactions in virtual reality can be quite different from what they are in actual reality. They found that contagious yawning happens in VR, but people's tendency to suppress yawns when they have company or feel they're being watched don't apply in the VR environment. Further, when people immersed in VR are awar

Whole-genome duplication (WGD) is considered a key evolutionary event for genetic innovation and has occurred in diverse eukaryotic lineages (1). In PNAS, Li et al. (2) report multiple WGD events in hexapods, which is surprising because WGD is thought to be disruptive in animals with chromosomal sex determination and therefore…
As we wrote in our original report of these events (1), readers should not rush to interpret the six ancient large-scale duplications in hexapods as whole-genome duplications (WGDs). Analyses of syntenic relationships are needed to understand the evolutionary processes underlying these large-scale duplications that we inferred with phylogenomic methods (1)….
For many marine fish species, the average size of individuals increases with depth. This phenomenon, first described a century ago, is known as ontogenetic deepening (1, 2). Several mechanisms have been proposed to explain it: optimal foraging; predation avoidance; and different optimal growth temperature for larger individuals, causing them to…
In their response to our paper "Exploitation drives an ontogenetic-like deepening in marine fish" (1), Baudron et al. (2) unfairly characterize our result as an alternative explanation. Throughout our paper, and in the closing remark, we explicitly state that additional factors must be considered: "Ontogenetic factors, fisheries exploitation, and climate…
Recently in PNAS, Luo et al. (1) report the observation of heteroplasmic mixtures of mitochondrial DNA (mtDNA) in the blood of three unrelated patients suffering from different mitochondrial disorders. The affected mixed positions coincide with signature mutations of established haplogroups (2), suggesting that each mixture consists of a different pair…
In Luo et al. (1), we report the transmission of paternal mtDNA in 17 individuals across three unrelated families. In their letter responding to this paper, Lutz-Bonengel et al. (2) argue that these results do not provide sufficient evidence for paternal inheritance of mtDNA. Instead, they propose that these biparental…
A comprehensive analysis of relative gene order, or microsynteny, can provide valuable information for understanding the evolutionary history of genes and genomes, and ultimately traits and species, across broad phylogenetic groups and divergence times. We have used our network-based phylogenomic synteny analysis pipeline to first analyze the overall patterns and…
Circulating tumor cells (CTCs) play a fundamental role in cancer progression. However, in mice, limited blood volume and the rarity of CTCs in the bloodstream preclude longitudinal, in-depth studies of these cells using existing liquid biopsy techniques. Here, we present an optofluidic system that continuously collects fluorescently labeled CTCs from…
Adaptive immune response is part of the dynamic changes that accompany motoneuron loss in amyotrophic lateral sclerosis (ALS). CD4+ T cells that regulate a protective immunity during the neurodegenerative process have received the most attention. CD8+ T cells are also observed in the spinal cord of patients and ALS mice…
Nectin-like (Necl) molecules are Ca2+-independent Ig-like transmembrane cell adhesion molecules that participate in junctions between different cell types. The specific cell–cell adhesions mediated by Necl proteins are important in neural development and have been implicated in neurodegenerative diseases. Here, we present the crystal structure of the mouse Necl-4 full ectodomain…
Reversible biological electron transfer usually occurs between redox couples at standard redox potentials ranging from +0.8 to −0.5 V. Dearomatizing benzoyl-CoA reductases (BCRs), key enzymes of the globally relevant microbial degradation of aromatic compounds at anoxic sites, catalyze a biological Birch reduction beyond the negative limit of this redox window….
Secondary hemophagocytic lymphohistiocytosis (sHLH) is a highly mortal complication associated with sepsis. In adults, it is often seen in the setting of infections, especially viral infections, but the mechanisms that underlie pathogenesis are unknown. sHLH is characterized by a hyperinflammatory state and the presence hemophagocytosis. We found that sequential challenging…
Extensive studies have detailed the molecular regulation of individual components of the hemostatic system, including platelets, coagulation factors, and regulatory proteins. Questions remain, however, about how these elements are integrated at the systems level within a rapidly changing physical environment. To answer some of these questions, we developed a puncture…
Inflammasomes are large protein complexes that trigger host defense in cells by activating inflammatory caspases for cytokine maturation and pyroptosis. NLRP6 is a sensor protein in the nucleotide-binding domain (NBD) and leucine-rich repeat (LRR)-containing (NLR) inflammasome family that has been shown to play multiple roles in regulating inflammation and host…
In antiviral RNA interference (RNAi), Dicer plays a primary role in processing double-stranded RNA (dsRNA) molecules into small-interfering RNAs (siRNAs) that guide Argonaute effectors to posttranscriptional suppression of target viral genes. Here, we show a distinct role for Dicer in the siRNA-independent transcriptional induction of certain host genes upon viral…
Angelman syndrome (AS) is a severe neurodevelopmental disorder caused by the loss of function from the maternal allele of UBE3A, a gene encoding an E3 ubiquitin ligase. UBE3A is only expressed from the maternally inherited allele in mature human neurons due to tissue-specific genomic imprinting. Imprinted expression of UBE3A is…
Activation of the integrated stress response (ISR) by a variety of stresses triggers phosphorylation of the α-subunit of translation initiation factor eIF2. P-eIF2α inhibits eIF2B, the guanine nucleotide exchange factor that recycles inactive eIF2•GDP to active eIF2•GTP. eIF2 phosphorylation thereby represses translation. Persistent activation of the ISR has been linked…
Microarchitectural cues drive aligned fibrillar collagen deposition in vivo and in biomaterial scaffolds, but the cell-signaling events that underlie this process are not well understood. Utilizing a multicellular patterning model system that allows for observation of intracellular signaling events during collagen matrix assembly, we investigated the role of calcium (Ca2+)…
The aggregation of monomeric amyloid β protein (Aβ) peptide into oligomers and amyloid fibrils in the mammalian brain is associated with Alzheimer's disease. Insight into the thermodynamic stability of the Aβ peptide in different polymeric states is fundamental to defining and predicting the aggregation process. Experimental determination of Aβ thermodynamic…
Animals are living in a microbial world. Bacteria, Archaea, and often eukaryotic microorganisms are ubiquitous and intimate associates of all multicellular organisms (1). Many of these microbes improve the fitness of their hosts by affecting multiple traits, including growth rates, immune function, nutrient allocation, and behavior (2). Squids are no…
Pre-mRNA splicing must occur with extremely high fidelity. Spliceosomes assemble onto pre-mRNA guided by specific sequences (5′ splice site, 3′ splice site, and branchpoint). When splice sites are mutated, as in many hereditary diseases, the spliceosome can aberrantly select nearby pseudo- or "cryptic" splice sites, often resulting in nonfunctional protein….
Self-replication and exponential growth are ubiquitous in nature but until recently there were few examples of artificial self-replication. Often replication is a templated process where a parent produces a single offspring, doubling the population in each generation. Many species however produce more than one offspring at a time, enabling faster…
The macaque dorsal occipital cortex is generally thought to contain an elongated third visual area, V3d, extending along most of the rostral border of area V2. In contrast, our submillimeter retinotopic fMRI maps (0.6-mm isotropic voxels, achieved by implanted phased-array receive coils) consistently show three sectors anterior to V2d. The…
Plant specialized metabolism (SM) enzymes produce lineage-specific metabolites with important ecological, evolutionary, and biotechnological implications. Using Arabidopsis thaliana as a model, we identified distinguishing characteristics of SM and GM (general metabolism, traditionally referred to as primary metabolism) genes through a detailed study of features including duplication pattern, sequ
Morphogenesis often yields organs with robust size and shapes, whereas cell growth and deformation feature significant spatiotemporal variability. Here, we investigate whether tissue responses to mechanical signals contribute to resolve this apparent paradox. We built a model of growing tissue made of fiber-like material, which may account for the cytoskeleton,…
A tumor is made up of a heterogeneous collection of cell types, all competing on a fitness landscape mediated by microenvironmental conditions that dictate their interactions. Despite the fact that much is known about cell signaling, cellular cooperation, and the functional constraints that affect cellular behavior, the specifics of how…
It is commonly believed that bacterial chemotaxis helps cells find food. However, not all attractants are nutrients, and not all nutrients are strong attractants. Here, by using microfluidic experiments, we studied Escherichia coli chemotaxis behavior in the presence of a strong chemoattractant (e.g., aspartate or methylaspartate) gradient and an opposing…
In nature, plants must respond to multiple stresses simultaneously, which likely demands cross-talk between stress-response pathways to minimize fitness costs. Here we provide genetic evidence that biotic and abiotic stress responses are differentially prioritized in Arabidopsis thaliana leaves of different ages to maintain growth and reproduction under combined biotic and…
In a new study out Wednesday, scientists reveal yet another reason to keep up on dental hygiene. Bacteria that cause a common yet largely preventable gum infection may also play a role in Alzheimer's disease. The discovery also offers hope for a treatment that could slow neurodegeneration. "There were many clues in the [features of Alzheimer's disease] that an infection is at work," said Casey Lyn

As coral species die off, they may be leaving a death spiral in their wake: Their absence could be sapping life from the corals that survive. In a new study, when isolated from other species, corals got weak, died off or grew in fragile structures. The study has shown it is possible to quantify positive effects of coral biodiversity and negative effects of its absence.
Scientists have discovered the relaxation dynamics of a zero-field state in skyrmions, a spinning magnetic phenomenon that has potential applications in data storage and spintronic devices.
Some people consider pufferfish, also known as fugu, a delicacy because of its unique and exquisite flavor, which is perhaps seasoned by knowledge that consumption of the fish could be deadly. Now, researchers have identified the major compounds responsible for the taste of pufferfish, minus the thrill of living dangerously.
Engineers have created the first 3D-printed fluid circuit element so tiny that 10 could rest on the width of a human hair. The diode ensures fluids move in only a single direction — a critical feature for products like implantable devices that release therapies directly into the body.
Researchers have found that a peptide hormone regulates two different cell division processes that generate centrally important structures for the flow of water through plants. By binding to different receptors, the hormone controls the formation of not only xylem (the vessels that transport water up from the roots), but also stomata (the leaf pores through which water evaporates).
Robot Work Responding to a nuclear disaster is no job for humans. Even while wearing protective suits, our bodies can't handle the radiation . It could be a job for robots, though. Researchers in the U.K. are developing a centaur-like robot designed to work in settings too dangerous for humans to navigate — and it could one day play a major role in disaster response efforts including nuclear cata

Lead exposure in childhood appears to have long-lasting negative effects on mental health and personality in adulthood, according to a study of people who grew up in the era of leaded gasoline. The findings reveal that the higher a person's blood lead levels at age 11, the more likely they are to show signs of mental illness and difficult personality traits by age 38.
A new advanced line of rice, with higher yield, is ready for final field testing prior to release. On average, it has a protein content of 10.6 percent, a 53 percent increase from its original protein content. It also needs less heat, time, and usually less water to cook.
Researchers have identified two novel anxiety-related genomic regions in German Shepherd dogs. The region associated with fearfulness corresponds with the locus of human chromosome 18, which is associated with various psychiatric disorders, while the region associated with noise sensitivity includes several genes related to human and canine behavior and mental disorders.
How fast the universe is expanding has been puzzling astronomers for almost a century. Different studies keep coming up with different answers — which has some researchers wondering if they've overlooked a key mechanism in the machinery that drives the cosmos. Now, by pioneering a new way to measure how quickly the cosmos is expanding, astronomers have taken a step toward resolving the debate.
After slowly forming stars for the first few billion years of their lives, the Magellanic Clouds, near neighbors of our own Milky Way galaxy, have upped their game and are now forming new stars at a fast clip. This new insight into the history of the Clouds comes from the first detailed chemical maps made of galaxies beyond the Milky Way.

This study aims to understand the effectiveness of typical admissions criteria in identifying students who will complete the Physics Ph.D. Multivariate statistical analysis of roughly one in eight physics Ph.D. students from 2000 to 2010 indicates that the traditional admissions metrics of undergraduate grade point average (GPA) and the Graduate Record Examination (GRE) Quantitative, Verbal, and
Porphyromonas gingivalis , the keystone pathogen in chronic periodontitis, was identified in the brain of Alzheimer's disease patients. Toxic proteases from the bacterium called gingipains were also identified in the brain of Alzheimer's patients, and levels correlated with tau and ubiquitin pathology. Oral P. gingivalis infection in mice resulted in brain colonization and increased production of
Earth's status as the only life-sustaining planet is a result of the timing and delivery mechanism of carbon (C), nitrogen (N), sulfur (S), and hydrogen (H). On the basis of their isotopic signatures, terrestrial volatiles are thought to have derived from carbonaceous chondrites, while the isotopic compositions of nonvolatile major and trace elements suggest that enstatite chondrite–like material
Drought and atmospheric aridity pose large risks to ecosystem services and agricultural production. However, these factors are seldom assessed together as compound events, although they often occur simultaneously. Drought stress on terrestrial carbon uptake is characterized by soil moisture (SM) deficit and high vapor pressure deficit (VPD). We used in situ observations and 15 Earth system models
The compositional and isotopic similarity of Earth's primitive upper mantle (PUM) and the Moon supports the derivation of the Moon from proto-Earth, but the Moon's inventory of volatile lithophile elements—Na, K, Rb, and Cs—is lower than Earth's PUM by factors of 4 to 5. The abundances of 14 other volatile elements exhibit siderophile behavior [volatile siderophile elements (VSEs); i.e., P, As, C
Compounds targeting the circadian clock have been identified as potential treatments for clock-related diseases, including cancer. Our cell-based phenotypic screen revealed uncharacterized clock-modulating compounds. Through affinity-based target deconvolution, we identified GO289, which strongly lengthened circadian period, as a potent and selective inhibitor of CK2. Phosphoproteomics identified
Specialized immune cell subsets are involved in autoimmune disease, cancer immunity, and infectious disease through a diverse range of functions mediated by overlapping pathways and signals. However, subset-specific responses may not be detectable in analyses of whole blood samples, and no efficient approach for profiling cell subsets at high throughput from small samples is available. We present
Segregation of homologous chromosomes in meiosis I is tightly regulated by their physical links, or crossovers (COs), generated from DNA double-strand breaks (DSBs) through meiotic homologous recombination. In budding yeast, three ZMM (Zip1/2/3/4, Mer3, Msh4/5) proteins, Zip2, Zip4, and Spo16, form a "ZZS" complex, functioning to promote meiotic recombination via a DSB repair pathway. Here, we id
We report that the apical dendrites of CA3 hippocampal pyramidal neurons are increased during labor and birth in the valproate model of autism but not in control animals. Using the iDISCO clearing method, we show that hippocampal, especially CA3 region, and neocortical volumes are increased and that the cerebral volume distribution shifts from normal to lognormal in valproate-treated animals.

Mesoscale turbulence in the ocean strongly affects the circulation, water mass formation, and transport of tracers. Little is known, however, about how mixing varies on climate timescales. We present the first time-resolved global dataset of lateral mesoscale eddy diffusivities at the ocean surface, obtained by applying the suppressed mixing length theory to satellite-observed velocities. We find
Many aggregating animals use aposematic signals to advertise their toxicity to predators. However, the coordination between aposematic signals and toxins is poorly understood. Here, we reveal that phenylacetonitrile (PAN) acts as an olfactory aposematic signal and precursor of hypertoxic hydrogen cyanide (HCN) to protect gregarious locusts from predation. We found that PAN biosynthesis from pheny
Scientists studying the relationship of telomeres to cancer made a surprising discovery: a cellular recycling process called autophagy — generally thought of as a survival mechanism — actually promotes the death of cells, thereby preventing cancer initiation.
A new study confirms the urgency to tackle climate change. While it's known that extreme weather events can affect the year-to-year variability in carbon uptake, and some researchers have suggested that there may be longer-term effects, this study is the first to actually quantify the effects through the 21st century and demonstrates that wetter-than-normal years do not compensate for losses in ca
