have demonstrated spatial resolutions down to 5 nm and localization precisions of 1 nm under certain in vitro conditions. However, such resolutions do not directly translate to experiments in cells, and Ångström resolution has not been demonstrated to date. Here we introdue a DNA-barcoding method, resolution enhancement by sequential imaging (RESI), that improves the resolution of fluorescence microscopy down to the Ångström scale using off-the-shelf fluorescence microscopy hardware and reagents. By sequentially imaging sparse target subsets at moderate spatial resolutions of >15 nm, we demonstrate that single-protein resolution can be achieved for biomolecules in whole intact cells. Furthermore, we experimentally resolve the DNA backbone distance of single bases in DNA origami with Ångström resolution. We use our method in a proof-of-principle demonstration to map the molecular arrangement of the immunotherapy target CD20 in situ in untreated and drug-treated cells, which opens possibilities for assessing the molecular mechanisms of targeted immunotherapy. These observations demonstrate that, by enabling intramolecular imaging under ambient conditions in whole intact cells, RESI closes the gap between super-resolution microscopy and structural biology studies and thus delivers information key to understanding complex biological systems.
The authors introduce a single-molecule DNA-barcoding method, resolution enhancement by sequential imaging, that improves the resolution of fluorescence microscopy down to the Ångström scale using off-the-shelf fluorescence microscopy hardware and reagents.

Outlive : the science & art of longevity
\"Wouldn't you like to live longer? And better? In this operating manual for longevity, Dr. Peter Attia draws on the latest science to deliver innovative nutritional interventions, techniques for optimizing exercise and sleep, and tools for addressing emotional and mental health. For all its successes, mainstream medicine has failed to make much progress against the diseases of aging that kill most people: heart disease, cancer, Alzheimer's disease, and type 2 diabetes. Too often, it intervenes with treatments too late to help, prolonging lifespan at the expense of healthspan, or quality of life. Dr. Attia believes we must replace this outdated framework with a personalized, proactive strategy for longevity, one where we take action now, rather than waiting. This is not 'biohacking,' it's science: a well-founded strategic and tactical approach to extending lifespan while also improving our physical, cognitive, and emotional health. Dr. Attia's aim is less to tell you what to do and more to help you learn how to think about long-term health, in order to create the best plan for you as an individual. In Outlive, readers will discover: Why the cholesterol test at your annual physical doesn't tell you enough about your actual risk of dying from a heart attack; that you may already suffer from an extremely common yet underdiagnosed liver condition that could be a precursor to the chronic diseases of aging; why exercise is the most potent pro-longevity 'drug'--and how to begin training for the 'Centenarian Decathlon\"; why you should forget about diets, and focus instead on nutritional biochemistry, using technology and data to personalize your eating pattern; why striving for physical health and longevity, but ignoring emotional health, could be the ultimate curse of all. Aging and longevity are far more malleable than we think; our fate is not set in stone. With the right roadmap, you can plot a different path for your life, one that lets you outlive your genes to make each decade better than the one before\"-- Provided by publisher.

Identifiers for the 21st century: How to design, provision, and reuse persistent identifiers to maximize utility and impact of life science data
In many disciplines, data are highly decentralized across thousands of online databases (repositories, registries, and knowledgebases). Wringing value from such databases depends on the discipline of data science and on the humble bricks and mortar that make integration possible; identifiers are a core component of this integration infrastructure. Drawing on our experience and on work by other groups, we outline 10 lessons we have learned about the identifier qualities and best practices that facilitate large-scale data integration. Specifically, we propose actions that identifier practitioners (database providers) should take in the design, provision and reuse of identifiers. We also outline the important considerations for those referencing identifiers in various circumstances, including by authors and data generators. While the importance and relevance of each lesson will vary by context, there is a need for increased awareness about how to avoid and manage common identifier problems, especially those related to persistence and web-accessibility/resolvability. We focus strongly on web-based identifiers in the life sciences; however, the principles are broadly relevant to other disciplines.

Pathogens for War : Biological Weapons, Canadian Life Scientists, and North American Biodefence
\"Pathogens for War explores how Canada and its allies have attempted to deal with the threat of germ warfare, one of the most fearful weapons of mass destruction, since the Second World War. In addressing this subject, distinguished historian Donald Avery investigates the relationship between bioweapons, poison gas, and nuclear devices, as well as the connection between bioattacks and natural disease pandemics. Avery emphasizes the crucially important activities of Canadian biodefence scientists - beginning with Nobel Laureate Frederick Banting - at both the national level and through cooperative projects within the framework of an elaborate alliance system\"--Preliminary page.

Genomics of perivascular space burden unravels early mechanisms of cerebral small vessel disease
Perivascular space (PVS) burden is an emerging, poorly understood, magnetic resonance imaging marker of cerebral small vessel disease, a leading cause of stroke and dementia. Genome-wide association studies in up to 40,095 participants (18 population-based cohorts, 66.3 ± 8.6 yr, 96.9% European ancestry) revealed 24 genome-wide significant PVS risk loci, mainly in the white matter. These were associated with white matter PVS already in young adults (
N
= 1,748; 22.1 ± 2.3 yr) and were enriched in early-onset leukodystrophy genes and genes expressed in fetal brain endothelial cells, suggesting early-life mechanisms. In total, 53% of white matter PVS risk loci showed nominally significant associations (27% after multiple-testing correction) in a Japanese population-based cohort (
N
= 2,862; 68.3 ± 5.3 yr). Mendelian randomization supported causal associations of high blood pressure with basal ganglia and hippocampal PVS, and of basal ganglia PVS and hippocampal PVS with stroke, accounting for blood pressure. Our findings provide insight into the biology of PVS and cerebral small vessel disease, pointing to pathways involving extracellular matrix, membrane transport and developmental processes, and the potential for genetically informed prioritization of drug targets.
Genomic analyses of large population-based cohorts uncover the genetic determinants of perivascular space burden, an MRI marker of cerebral small vessel disease, across the lifespan, and reveal potential pathways implicated in the etiology of stroke and dementia.

Persistence of false paradigms in low-power sciences
We develop a model describing how false paradigms may persist, hindering scientific progress. The model features two paradigms, one describing reality better than the other. Tenured scientists display homophily: They favor tenure candidates who adhere to their paradigm. As in statistics, power is the probability (absent any bias) of denying tenure to scientists adhering to the false paradigm. The model shows that because of homophily, when power is low, the false paradigm may prevail. Then, only an increase in power can ignite convergence to the true paradigm. Historical case studies suggest that low power comes either from lack of empirical evidence or from reluctance to base tenure decisions on available evidence.

Life as Surplus
Focusing on the period between the 1970s and the present, Life as Surplus is a pointed and important study of the relationship between politics, economics, science, and cultural values in the United States today. Melinda Cooper demonstrates that the history of biotechnology cannot be understood without taking into account the simultaneous rise of neoliberalism as a political force and an economic policy. From the development of recombinant DNA technology in the 1970s to the second Bush administration's policies on stem cell research, Cooper connects the utopian polemic of free-market capitalism with growing internal contradictions of the commercialized life sciences.
The biotech revolution relocated economic production at the genetic, microbial, and cellular level. Taking as her point of departure the assumption that life has been drawn into the circuits of value creation, Cooper underscores the relations between scientific, economic, political, and social practices. In penetrating analyses of Reagan-era science policy, the militarization of the life sciences, HIV politics, pharmaceutical imperialism, tissue engineering, stem cell science, and the pro-life movement, the author examines the speculative impulses that have animated the growth of the bioeconomy.
At the very core of the new post-industrial economy is the transformation of biological life into surplus value. Life as Surplus offers a clear assessment of both the transformative, therapeutic dimensions of the contemporary life sciences and the violence, obligation, and debt servitude crystallizing around the emerging bioeconomy.

Nonlinear magic: multiphoton microscopy in the biosciences
Multiphoton microscopy (MPM) has found a niche in the world of biological imaging as the best noninvasive means of fluorescence microscopy in tissue explants and living animals. Coupled with transgenic mouse models of disease and 'smart' genetically encoded fluorescent indicators, its use is now increasing exponentially. Properly applied, it is capable of measuring calcium transients 500 μm deep in a mouse brain, or quantifying blood flow by imaging shadows of blood cells as they race through capillaries. With the multitude of possibilities afforded by variations of nonlinear optics and localized photochemistry, it is possible to image collagen fibrils directly within tissue through nonlinear scattering, or release caged compounds in sub-femtoliter volumes.
