    I hate to be the one to defend Facebook but they're doing nothing of the sort. If your post is flagged/reported by someone that reads it as selling a regulated product, not just a firearm, then the poster gets a notification reminding them to comply with applicable laws. The only thing they're really doing is interpreting statements like "no background check required" as a sign that the poster might be willing to help evade the law. They're not requiring the poster to perform a background check, they're just don't want the lack there of to be a selling point. This story is making a mountain out of an anthill.

  13. Article text on Researchers Develop Solid But Flexible Electrolyte For Bendable Batteries · · Score: -1

    Rechargeable lithium-ion batteries, the most popular energy source for mobile electronic devices, are rapidly expanding their range of applications into fields such as electrical vehicles, grid energies, and flexible electronic devices.1 This strong market demand stimulates the need for development of advanced lithium ion battery technologies capable of improving energy storage densities, cycle life, charge/discharge rates, and design flexibility.2, 3

    One strategy to address certain of these goals involves advanced structural design in the electrodes, along with associated new material development. For example, three dimensional (3D) electrodes can yield improvements in rate capability and capacity retention.4–6 These advantages are further enhanced in high-capacity anode materials, such as silicon and tin, which undergo large changes in volume during charge/discharge cycling.7, 8 One challenge for 3D electrodes, particularly in integration of active components, arises from difficulties in securing conformal electrolytes that can also prevent electrical shorts between electrodes.6 Although liquid electrolytes ensure excellent electrochemical performance and good physical contact with 3D electrodes, they suffer from potential leakage, leading to safety concerns. More importantly, liquid electrolytes limit choices in cell design due to their fluidic characteristics and the need for separator membranes in cell assembly. This situation motivates the development of self-supporting solid-state electrolytes that can conform to 3D electrodes and, at the same time, provide sufficient mechanical deformability for reliable use, especially for applications in flexible electronics and other demanding areas of envisioned use.

    Among various solid-state electrolytes, gel polymer electrolytes (GPEs), which are generally composed of polymer matrix and liquid electrolyte, are widely used in lithium-ion batteries owing to their excellent ionic conductivity, low rates of safety failure, and mechanical flexibility.9–11 In general, conventional GPEs are prepared using a predesigned frame via solution casting of liquid state mixtures (i.e., liquid electrolytes and polymers dissolved in organic solvents or liquid electrolytes/polymerizable monomers), followed by solvent evaporation or chemical cross-linking for solidification. The initial, liquid-state, mixtures for GPEs have limited dimensional stability before solidification due to their intrinsically fluidic characteristics, thereby restricting their facile application to complex-structured systems such as 3D batteries.

    To the best of our knowledge, there are no polymer electrolytes that are both shape-conformable to 3D electrodes and mechanically flexible without impairing their electrochemical performance. Moreover, it is still challenging to secure dimensional stability (as a solid form) of polymer electrolytes during electrolyte preparation and cell assembly process.6, 12

    In the following, we demonstrate a facile and scalable approach to the fabrication of highly ion-conductive and bendable polymer electrolytes that can be also conformable to 3D micropatterned architectures of electrodes over large areas. These polymer electrolytes can also be directly writable or printable onto substrates of interest (including electrodes with complex geometries) due to well-tuned rheological characteristics. The materials are a kind of composite gel polymer electrolyte (hereinafter, referred to as “c-GPE”), composed of a UV (ultraviolet)-cured ethoxylated trimethylolpropane triacrylate (ETPTA) polymer matrix, high-boiling point liquid electrolyte (1M LiPF6 in ethylene carbonate (EC)/propylene carbonate (PC) = 1/1 (v/v)), and alumina (Al2O3) nanoparticles (Figure 1a). The ETPTA monomer, which contains trivalent vinyl groups that participate in UV-crosslinking,13, 14 serves as a mechanical framework (after UV-curing). The chemical structure of the ETPTA, along with 2-hydroxy-2-methyl-1-phenyl-1-propanon (HMPP, a photo-initiator), appears in Figure S1 in E

  22. HTFA on Majority of Landmark Cancer Studies Cannot Be Replicated · · Score: -1, Flamebait

    Efforts over the past decade to characterize the genetic alterations in human cancers have led to a better understanding of molecular drivers of this complex set of diseases. Although we in the cancer field hoped that this would lead to more effective drugs, historically, our ability to translate cancer research to clinical success has been remarkably low1. Sadly, clinical trials in oncology have the highest failure rate compared with other therapeutic areas. Given the high unmet need in oncology, it is understandable that barriers to clinical development may be lower than for other disease areas, and a larger number of drugs with suboptimal preclinical validation will enter oncology trials. However, this low success rate is not sustainable or acceptable, and investigators must reassess their approach to translating discovery research into greater clinical success and impact.

    Many factors are responsible for the high failure rate, notwithstanding the inherently difficult nature of this disease. Certainly, the limitations of preclinical tools such as inadequate cancer-cell-line and mouse models2 make it difficult for even the best scientists working in optimal conditions to make a discovery that will ultimately have an impact in the clinic. Issues related to clinical-trial design — such as uncontrolled phase II studies, a reliance on standard criteria for evaluating tumour response and the challenges of selecting patients prospectively — also play a significant part in the dismal success rate3.

    S. GSCHMEISSNER/SPL

    Many landmark findings in preclinical oncology research are not reproducible, in part because of inadequate cell lines and animal models.

    Unquestionably, a significant contributor to failure in oncology trials is the quality of published preclinical data. Drug development relies heavily on the literature, especially with regards to new targets and biology. Moreover, clinical endpoints in cancer are defined mainly in terms of patient survival, rather than by the intermediate endpoints seen in other disciplines (for example, cholesterol levels for statins). Thus, it takes many years before the clinical applicability of initial preclinical observations is known. The results of preclinical studies must therefore be very robust to withstand the rigours and challenges of clinical trials, stemming from the heterogeneity of both tumours and patients.

    Confirming research findings
    The scientific community assumes that the claims in a preclinical study can be taken at face value — that although there might be some errors in detail, the main message of the paper can be relied on and the data will, for the most part, stand the test of time. Unfortunately, this is not always the case. Although the issue of irreproducible data has been discussed between scientists for decades, it has recently received greater attention (see go.nature.com/q7i2up) as the costs of drug development have increased along with the number of late-stage clinical-trial failures and the demand for more effective therapies.

    Over the past decade, before pursuing a particular line of research, scientists (including C.G.B.) in the haematology and oncology department at the biotechnology firm Amgen in Thousand Oaks, California, tried to confirm published findings related to that work. Fifty-three papers were deemed 'landmark' studies (see 'Reproducibility of research findings'). It was acknowledged from the outset that some of the data might not hold up, because papers were deliberately selected that described something completely new, such as fresh approaches to targeting cancers or alternative clinical uses for existing therapeutics. Nevertheless, scientific findings were confirmed in only 6 (11%) cases. Even knowing the limitations of preclinical research, this was a shocking result.
