While the compressive strength-density scaling relationship of ultralight cellular graphene materials has been extensively investigated, high tensile strength and ductility have not been realized in the theoretically strongest carbon materials because of high flaw sensitivity under tension and weak van der Waals interplanar bonding between graphene sheets. In this study, we report that large-scal
Evaluation of observed sea level rise impacts to date has emphasized sea level extremes, such as those from tropical cyclones. Far less is known about the consequences of more frequent high-tide flooding. Empirical analysis of the disruption caused by high-tide floods, also called nuisance or sunny-day floods, is challenging due to the short duration of these floods and their impacts. Through a n
An important goal of the scientific community is broadening the achievement and participation of racial minorities in STEM fields. Yet, professors' beliefs about the fixedness of ability may be an unwitting and overlooked barrier for stigmatized students. Results from a longitudinal university-wide sample (150 STEM professors and more than 15,000 students) revealed that the racial achievement gap
Collocated data processing and storage are the norm in biological computing systems such as the mammalian brain. As our ability to create better hardware improves, new computational paradigms are being explored beyond von Neumann architectures. Integrated photonic circuits are an attractive solution for on-chip computing which can leverage the increased speed and bandwidth potential of the optica
Researchers have long wondered whether ferroelectrics may present topological textures akin to magnetic skyrmions and chiral bubbles, the results being modest thus far. An electric equivalent of a typical magnetic skyrmion would rely on a counterpart of the Dzyaloshinskii-Moriya interaction and seems all but impossible; further, the exotic ferroelectric orders reported to date rely on specific co
Recently, the complexity behind manipulations of reflected fields by metasurfaces has been addressed, showing that, even in the simplest scenarios, nonlocal response and excitation of auxiliary evanescent fields are required for perfect field control. In this work, we introduce purely local reflective metasurfaces for arbitrary manipulations of the power distribution of reflected waves without ex
The uncontrollable growth of lithium (Li) dendrites seriously impedes practical applications of Li metal batteries. Various lithiophilic conductive frameworks, especially carbon hosts, are used to guide uniform Li nucleation and thus deliver a dendrite-free composite anode. However, the lithiophilic nature of these carbon hosts is poorly understood. Herein, the lithiophilicity chemistry of hetero
One source of instability in perovskite solar cells (PSCs) is interfacial defects, particularly those that exist between the perovskite and the hole transport layer (HTL). We demonstrate that thermally evaporated dopant-free tetracene (120 nm) on top of the perovskite layer, capped with a lithium-doped Spiro-OMeTAD layer (200 nm) and top gold electrode, offers an excellent hole-extracting stack w
Pure liquids in thermodynamic equilibrium are structurally homogeneous. In liquid crystals, flow and light pulses are used to create reconfigurable domains with polar order. Moreover, through careful engineering of concerted microfluidic flows and localized optothermal fields, it is possible to achieve complete control over the nucleation, growth, and shape of such domains. Experiments, theory, a
Herein, we report the synthesis of uniform hollow nanorods of Ni-doped FeP nanocrystals hybridized with carbon as electrocataysts for the electrocatalytic hydrogen evolution reaction (HER).

Thus far only tidal tails of massive globular clusters and dwarf galaxies have been discovered in the Milky Way system. In open clusters, this phenomenon existed only in theory. Researchers at Heid
The premise of 2017's Happy Death Day is a perfect elevator pitch: What if Groundhog Day were a horror film? Theresa (Jessica Rothe) wakes up in a college dorm room, goes through her routine, and then dies at the hands of a masked serial killer, becoming the first murder victim of the movie. Except when she dies, she wakes up back in that dorm, at the start of the day again, doomed to relive the
Recently, the Australian Association for the Teaching of English (AATE)—the peak professional body for Australian English teachers—published a special issue of the journal English in Australia entitled "Love in English." It addressed the continued marginalisation of some genders and sexualities within the classroom.
Reports of malicious and targeted cyber attacks are becoming increasingly common around the world. In early February, for example, Australia's security agencies revealed there were investigating an attempted hack on the country's parliament, and hadn't ruled out another country being behind it.
One For All Californians may soon get a cut of the proceeds when tech giants like Facebook sell their personal data. Governor Gavin Newsom announced his support for such an initiative during his State of the State address on Tuesday, according to Gizmodo — a move that could permanently upset the balance of power between the world's biggest tech corporations and their users. "Companies that make b
Why did the hominin cross the plain? We may never know. But anthropologists are pretty sure that a smattering of bare footprints preserved in volcanic ash in Laetoli, Tanzania bear witness to an evolutionary milestone. These small steps, taken roughly 3.5 million years ago, mark an early successful attempt by our common human ancestor to stand upright and stride on two feet, instead of four.
Agriculture has become a carbon-intensive endeavour. Crop, livestock and fossil fuel use in agriculture account for about 25 per cent of global greenhouse gas (GHG) emissions.

Coccolithophores are microscopic marine algae that use carbon dioxide to grow, and release carbon dioxide when they create their miniature calcite shells. These tiny, abundant planktonic microorganisms could therefore be seriously impacted by current increasing carbon dioxide emissions. Scientists from the CNRS, Le Mans Université, Sorbonne Université, Aix-Marseille Université and the ESRF, the Eu
The higher the income of individuals living in Switzerland, the higher their greenhouse gas emissions. But to what extent do differences in income actually have an effect on emissions, and to what extent do household emissions differ? The main differences were found in the areas of mobility and housing. For nutrition, the differences in individual emissions are less pronounced. These are the findi

Nordjysk forsøg med telemedicin viser, at sundhedsvæsenet kan spare 40.000 kr. om året pr. hjertepatient. Frem for helbredsmæssige gevinster ved telemedicin bør sundhedsvæsenet fokusere på besparelser og øget tryghed hos borgerne, mener sundhedsøkonom Lars Ehlers.
Regeringen skubber sundhedsvæsenet foran sig i et mere og mere skingert forspil til valgkamp. Lad os få valget overstået, så de topprofessionelle medarbejdere i sundhedsvæsenet kan få ro til deres arbejde.
Problemet med prioritering i sundhedsvæsenet 'løses' med tomme ord, utilstrækkelige ekstrabevillinger og grønthøsterbesparelser. Og hvis det går, som det plejer i et valgår, så slutter debatten, når en mere presserende dagsorden rydder nyhedsfladen.
Både patienter og samfund stor gavn af et godt samarbejde mellem sundhedspersoner og virksomheder, som udvikler ny medicin og sundhedsteknologi. Det er dog en forudsætning, at der er åbenhed og transparens om samarbejdet, og at sundhedspersonerne ikke påvirkes af økonomiske interesser. Derfor skal alle i sundhedsvæsenet og industrien have kendskab til og efterleve habilitetskravene.

Poly(cyclohexylglycolide) (PCG)-based chiral block copolymers (BCPs*), poly(benzyl methacrylate)-b-poly(d-cyclohexylglycolide) (PBnMA-PDCG) and PBnMA-b-poly(l-cyclohexyl glycolide) (PBnMA-PLCG), were synthesized for purposes of systematic comparison with polylactide
The nuclear lamina is an intermediate filament meshwork adjacent to the inner nuclear membrane (INM) that plays a critical role in maintaining nuclear shape and regulating gene expression through chromatin interactions. Studies have demonstrated that A- and B-type lamins, the filamentous proteins that make up the nuclear lamina, form independent…
Digital droplet assays—in which biological samples are compartmentalized into millions of femtoliter-volume droplets and interrogated individually—have generated enormous enthusiasm for their ability to detect biomarkers with single-molecule sensitivity. These assays have untapped potential for point-of-care diagnostics but are currently mainly confined to laboratory settings, due to the instrumen
Color discrimination in the vertebrate retina is mediated by a combination of spectrally distinct cone photoreceptors, each expressing one of multiple cone opsins. The opsin genes diverged early in vertebrate evolution into four classes maximally sensitive to varying wavelengths of light: UV (SWS1), blue (SWS2), green (RH2), and red (LWS)…
Acid–base reactions are ubiquitous in nature. Understanding their mechanisms is crucial in many fields, from biochemistry to industrial catalysis. Unfortunately, experiments give only limited information without much insight into the molecular behavior. Atomistic simulations could complement experiments and shed precious light on microscopic mechanisms. The large free-energy barriers connected to.
Previous studies have shown that insulin and IGF-1 signaling in the brain, especially the hypothalamus, is important for regulation of systemic metabolism. Here, we develop mice in which we have specifically inactivated both insulin receptors (IRs) and IGF-1 receptors (IGF1Rs) in the hippocampus (Hippo-DKO) or central amygdala (CeA-DKO) by stereotaxic…
Theoretical and computational models such as transfer-appropriate processing (TAP) and global matching models have emphasized the encoding–retrieval interaction of memory representations in generating false memories, but relevant neural mechanisms are still poorly understood. By manipulating the sensory modalities (visual and auditory) at different processing stages (learning and test) in the…
Accumulating evidence indicates that the immune system does not develop in a linear fashion, but rather as distinct developmental layers formed from sequential waves of hematopoietic stem cells, each giving rise to unique populations of immune cells at different stages of development. Although recent studies have indicated that conventional CD8+…
The development of the cerebellum depends on intricate processes of neurogenesis, migration, and differentiation of neural stem cells (NSCs) and progenitor cells. Defective cerebellar development often results in motor dysfunctions and psychiatric disorders. Understanding the molecular mechanisms that underlie the complex development of the cerebellum will facilitate the development of…
Activity-dependent translation requires the transport of mRNAs within membraneless protein assemblies known as neuronal granules from the cell body toward synaptic regions. Translation of mRNA is inhibited in these granules during transport but quickly activated in response to neuronal stimuli at the synapse. This raises an important question: how does…
Materials can be classified by the topological character of their electronic structure and, in this perspective, global attributes immune to local deformations have been discussed in terms of Berry curvature and Chern numbers. Except for instructional simple models, linear response theories have been ubiquitously used in calculations of topological properties…
Therapeutic mAbs must not only bind to their target but must also be free from "developability issues" such as poor stability or high levels of aggregation.

U.S. Senator Bernie Sanders has been calling himself a democratic socialist since the 1960s. Bernie's use of the word "socialist" has attracted both love and ire from the left. His definition of socialism is vague, but is the basis for many peoples' understanding of the concept. The unexpected level of serious consideration that many Americans are giving to socialism is due, in large part, to the
In order to understand how our brains work, scientists have often made use of the fact that other animals share brains that seem similar to ours. We learned how neurons work by studying the squid, how vision and locomotion work by studying cats, and now look to mice and rats to gain insight into how computations are performed in groups of neurons. However, the danger of such an approach is that i
