Op mod 650.000 danskere lider af osteoporose – langt størstedelen uden selv at vide det. Osteoporose har ingen symptomer, før det første brud indtræffer. Denne bog om en af de store folkesygdomme i Danmark er skrevet til alle, der har osteoporose inde på livet – som ramt, påvirket eller fagperson – og som ønsker at blive klogere. Bogen igennem tages der udgangspunkt i de spørgsmål, som forfatterne Lars Hyldstrup og Jens-Erik Beck Jensen i årevis har fået fra osteoporosepatienter, og de svar, man aktuelt kan give herpå. Bogen er rigt illustreret af uddybende faktabokse, forklarende figurer og visuelle grafer, der hjælper med at formidle al den data og forskning, som ligger til grund for den aktuelle viden om osteoporose.Bliv fx klogere på:Knoglernes biologiForskellige typer af knoglebrudÅrsager og risikofaktorerSymptomer og differentialdiagnoserDiagnostik og undersøgelsesmetoderRåd til knoglesund livsstilMedicinsk behandlingVejledning om fysisk aktivitetForsknings- og patientmiljøerBogen er opslagsvenlig, så man nemt kan finde svar på specifikke spørgsmål, men den kan ligeledes læses i sin helhed for en grundig indføring i sygdommen.

A revelation' SATHNAM SANGHERA'Thrilling and eye-opening' LEWIS DARTNELL'Science and history at its best' MARK HONIGSBAUM'Unpicks everything we thought we knew... Mind blowing' CAL FLYNIn this revelatory book, Dr Jonathan Kennedy argues that germs have shaped humanity at every stage, from the first success of Homo sapiens over the equally intelligent Neanderthals to the fall of Rome and the rise of Islam.How did an Indonesian volcano help cause the Black Death, setting Europe on the road to capitalism? How could 168 men extract the largest ransom in history from an opposing army of eighty thousand? And why did the Industrial Revolution lead to the birth of the modern welfare state?The latest science reveals that infectious diseases are not just something that happens to us, but a fundamental part of who we are. Indeed, the only reason humans don't lay eggs is that a virus long ago inserted itself into our DNA, and there are as many bacteria in your body as there are human cells. We have been thinking about the survival of the fittest all wrong: evolution is not simply about human strength and intelligence, but about how we live and thrive in a world dominated by microbes.By exploring the startling intimacy of our relationship with infectious diseases, Kennedy shows how they have been responsible for some of the seismic revolutions of the past 50,000 years. Provocative and brimming with insight, Pathogenesis transforms our understanding of the human story, revealing how the crisis of a pandemic can offer vital opportunities for change.

When Oliver Sacks was twelve years old, a perceptive schoolmaster wrote in his report: 'Sacks will go far, if he does not go too far'. It is now abundantly clear that Sacks has never stopped going. From its opening pages on his youthful obsession with motorcycles and speed, On the Move is infused with his restless energy. As he recounts his experiences as a young neurologist in the early 1960s, first in California and then in New York, where he discovered a long-forgotten illness in the back wards of a chronic hospital, as well as with a group of patients who would define his life, it becomes clear that Sacks's earnest desire for engagement has occasioned unexpected encounters and travels - sending him through bars and alleys, over oceans, and across continents.With unbridled honesty and humour, Sacks shows us that the same energy that drives his physical passions - bodybuilding, weightlifting, and swimming - also drives his cerebral passions. He writes about his love affairs, both romantic and intellectual, his guilt over leaving his family to come to America, his bond with his schizophrenic brother, and the writers and scientists - Thom Gunn, A. R. Luria, W. H. Auden, Gerald M. Edelman, Francis Crick - who influenced him.On the Move is the story of a brilliantly unconventional physician and writer - and of the man who has illuminated the many ways that the brain makes us human.

Hvordan behandler man angstsygdomme og stresstilstande?Hvis ikke man selv oplever udtalt angst eller stress, er der stor sandsynlighed for, at man er pårørende til én eller flere, der gør, for angst er en folkesygdom, og stresssymptomer er hyppigt forekommende. Da mange af symptomerne på angst og stress er de samme, kan det være svært at skelne mellem tilstandene, og stress kan endda udløse eller forværre en angsttilstand.I HVAD ER ANGST OG STRESS? gennemgår og formidler to af landets førende professorer og læger inden for psykiatri den aktuelle viden om angst og stress på en måde, så både fagpersoner og den almene læser kan være med. Bogen behandler i 17 kapitler bl.a.: stress, angsttilstandene panikangst, agorafobi, socialfobi, enkelfobi, generaliseret angst, OCD og PTSD, symptomer, diagnostik og differentialdiagnoser, udvikling og forløb, årsager og konsekvenser, forebyggelse og behandlingsprincipper, pårørendes rolle, afstigmatisering, etik og jura. Bogen kan læses fra ende til anden for en dækkende indføring i angst og stress eller bruges som opslagsværk til belysning af specifikke emner. Sygehistorier og nøglereferencer undervejs giver læseren mulighed for at dykke yderligere ned i den angst- og stressramtes udfordringer, behandling og fremtidsudsigter.

A GUIDE TO USING THE SCIENCE OF THE BODY CLOCK TO CREATE THE OPTIMUM PERSONAL ROUTINE. SLEEP BETTER, WORK BETTER, FEEL BETTER.'A superlative guide to some of the most intriguing questions of human existence' Bill BrysonIn the twenty-first century, we increasingly push our daily routines into the night, carrying out work, exercise and our social lives long after dark. But we have forgotten that our bodies are governed by a 24-hour biological clock which guides us towards the best time to sleep, eat and think. New science has proven that living out of sync with this clock is not only disrupting our sleep, but leaving us more vulnerable to infection, cancer, obesity, type 2 diabetes, heart disease and mental illness.In Life Time, Professor Russell Foster shares his life's work, taking us on a fascinating and surprising journey through the science of our body clocks. Using his own studies, as well as insights from an international community of sleep scientists and biologists studying circadian rhythms, he illustrates the surprising effects the time of day can have on our health:- how a walk outside at dawn can ensure a better night's sleep- how eating after sundown can affect our weight- the extraordinary effects the time we take our medication can have on our risk of life-threatening conditions, such as strokesIn the modern world, we have neglected an essential part of our biology. But with knowledge of this astonishing science, we can get back into the rhythm, and live healthier, sharper lives.

'An invaluable companion for anyone who wants a deep understanding of what's under the hood of often inscrutable machines' Melanie Mitchell A rich, narrative explanation of the mathematics that has brought us machine learning and the ongoing explosion of artificial intelligenceMachine-learning systems are making life-altering decisions for us: approving mortgage loans, determining whether a tumour is cancerous, or deciding whether someone gets bail. They now influence discoveries in chemistry, biology and physics - the study of genomes, extra-solar planets, even the intricacies of quantum systems.We are living through a revolution in artificial intelligence that is not slowing down. This major shift is based on simple mathematics, some of which goes back centuries: linear algebra and calculus, the stuff of eighteenth-century mathematics. Indeed by the mid-1850s, a lot of the groundwork was all done. It took the development of computer science and the kindling of 1990s computer chips designed for video games to ignite the explosion of AI that we see all around us today. In this enlightening book, Anil Ananthaswamy explains the fundamental maths behind AI, which suggests that the basics of natural and artificial intelligence might follow the same mathematical rules.As Ananthaswamy resonantly concludes, to make the most of our most wondrous technologies we need to understand their profound limitations - the clues lie in the maths that makes AI possible.

In the early 1960s scientists at the University of California, Berkeley set out to establish the key factors effecting health and longevity. Their results, known as the ?Alameda 7', you already know: don't smoke, drink in moderation, sleep seven to eight hours a night, exercise, eat regular meals, maintain a moderate weight, eat breakfast. Years later, however, the same team discovered an eighth factor, one that proved more important than all the others: social connection.When we form meaningful bonds with others, our wounds heal faster, we shake off infections more quickly and our blood pressure drops. We are less likely to have Alzheimer's, heart attacks or strokes. When people feel that they have strong social support, they perform better on tests of mental focus, memory and problem solving. Greater connection can fuel creativity, increase our financial stability and enhance our work productivity. But making friends can also be daunting.In The Laws of Connection, David Robson does two important things: he takes us through the fascinating science behind the effects of social connection and he unpacks the research that shows that we are all better at being social than we might think. We will meet ideas such as ?the liking gap' and ?the gratitude gap', learn to recognise ?frenemies' and discover a powerful conversational strategy known as the ?fast-friends procedure' that promotes instant rapport. Being social doesn't have to mean having dozens of friends, it can also mean having one true, deep connection with another person. As Robson shows, we can all benefit from the laws of connection.

Dette er beretningen om, hvordan vi har mistet vores sunde forhold til tid og fordelene ved at vinde det tilbage.Vi taler om tid konstant, og det er et af de navneord, vi bruger allermest. Alligevel har vi en meget begrænset forståelse af, hvad tid egentlig er, og det er svært for os at forklare det. Vi er blevet uendelig dygtige til at måle tid og derudover blevet enige om fælles globale standarder fortid. Det har vist sig særdeles nyttigt i vores indretning af både privat- og arbejdsliv, og det er helt grundlæggende for en række teknologiske innovationer, kommunikation, transport og meget mere. Men tid giver også frustration og stress - vi har aldrig nok tid i vores travle hverdag, vi ærgrer os over, at vores biologiske ur tikker derudaf, og vi bekymrer os over beslutningstagernes mangel på langsigtede overvejelser. Men hvad nu, hvis vi kunne bevare de gode aspekter ved tid og lære at håndtere de dårlige ved at få en bedre forståelse af, hvad tid egentlig er? Denne bog ser på begrebet tid gennem 10 forskellige linser, bl.a. fysik, filosofi, kunst og litteratur, forretningsliv og neurovidenskab. Formålet er at give læseren en bedre forståelse af tid samt at illustrere fordelene ved at komme vores selvforvoldte, dårlige tidsvaner til livs.

Akupunktur, healing, zoneterapi, kinesiologi – Virker det? Hver anden dansker har prøvet alternativ behandling. De alter­­native terapeuter modtager årligt halvanden million patienter. Området har en omsætning i mil­li­ard­­klassen, og flere politikere vil gerne have det alternative ind under det offentlige sundhedssystem. FOD PÅ ALTERNATIV BEHANDLING undersøger i modsætning til de fleste andre bøger om emnet, om de populære terapier virker eller ej. Og den forklarer, hvorfor brugerne ofte er tilfredse med den behandling, de får. Det er populærvidenskab med skarp vinkel, underholdende og undertiden kontroversielt.

Hvad finder Danmarks bedste forskere svar på – lige nu? Hvad holder dem vågne om natten? Og hvad betyder deres opdagelser for både menneskehedens fremtid og din hverdag?Videnskab fra vilde hjerner giver et unikt indblik i den nyeste viden fra en række af Danmarks topforskere. Her fortæller de om både det, de ved, og om det, de gør. Om de fascinerende metoder, de bruger til at kortlægge verden, og om hvordan tilsyneladende tilfældigt opdagede indsigter bliver til afgørende innovation, der ændrer vores samfund for altid.Bogen bygger på podcasten Videnskab fra vilde hjerner, hvor astrofysiker og professor Anja C. Andersen sammen med Mikkel Frey Damgaard og Mette Holbæk har interviewet en perlerække af indsigtsfulde forskere. I bogen kan du møde nobelpristager og kemiker Morten Meldal, epidemiforsker Lone Simonsen, psykolog Svend Brinkmann, professor i strafferet Trine Baumbach, oceanograf Katherine Richardson, geolog Minik Rosing og 15 andre vilde hjerner.Anja C. Andersen fortæller også om, hvad de mange samtaler med forskerkollegaerne har lært hende om forskningens inderste væsen: Hvordan vi kun kan skabe ny viden i samarbejde med andre; hvorfor vi skal bevare vores barnlige nysgerrighed; og hvordan vi alle sammen kan lære at tænke lidt mere som en forsker.”Menneskeheden kan kun udvikle sig, hvis vi bruger både tid og ressourcer på at stille nysgerrige spørgsmål. Og være åben for temmelig overraskende svar. Vi kan ændre verden med vild tænkning.” – Anja C. Andersen

'The 'Enfant terrible' of astrophysics . . . Loeb has a joy in conjecture and an omnivorous spirit of inquiry that are more reminiscent of 20th-century thinkers such as Freeman Dyson or Carl Sagan than most of his peers' The TimesCould we build space craft that could travel to distant stars? Could we augment human biology for spaceflight? Could the search for extraterrestrials be brought into the mainstream of scientific research?Avi Loeb tells us that in each case, the real question is not could we, but will we choose to? With an approach that is firmly grounded in cutting-edge science, he explores the potential for non-rocket space launch, deep space probes, and the technological preservation of human civilisation. He examines the evidence for UFOs and UAPs, and argues that the search for further evidence, using existing scientific technologies, is long overdue.Urgent and important, Noah's Spaceship is a mission statement and a blueprint for the future of humanity. Loeb explains why becoming interstellar is imperative for our civilization to survive - and how we can accomplish it.'One of the more imaginative and articulate scientists around' New York Times

From the 2021 Nobel Prize winner in Physics, a remarkable journey into the practice of groundbreaking science 'Giorgio Parisi is renowned for his scientific creativity, originality, and power. In this exhilarating little book, he shows his human side, too. By its end, readers will feel they've made a charming, witty new friend' Frank WilczekThe world is shaped by complexity. In this enlightening book, Nobel Prize winner Giorgio Parisi guides us through his unorthodox yet exhilarating work to show us how. It all starts with investigating the principles of physics by observing the sophisticated flight patterns of starlings. Studying the movements of these birds, he has realized, proves an illuminating way into understanding complex systems of all kinds - collections of everything from atoms to planets to other animals like ourselves. Along the way, Parisi reflects on the lessons he's taken from a life in pursuit of scientific truth: the importance of serendipity to the discovery of new ideas, the surprising kinship between physics and other fields of study and the value of science to a thriving society. In so doing, he removes the practice of science from the confines of the laboratory and into the real world. Complexity is all around us - from climate to finance to biology, it offers a unique way of finding order in chaos. Part elegant scientific treatise, part thrilling intellectual journey, In a Flight of Starlings is an invitation to find wonder in the world around us.

Den moderne neurovidenskab har placeret hjernen som udgangspunkt for studiet af mennesket. Men hvad nu hvis forskningen ikke så på hjernen som kilden til livet, men som et organ i og for et levende væsen? ‘Hjernens økologi’ tager dét udgangspunkt. Den peger på, at vi ikke kan forstå hjernen, før vi har et begreb om det levende. Og undersøger dernæst den menneskelige krop som et levende væsen, der bruger hjernen til at etablere forhold – både indre forhold mellem dele af den menneskelige krop og forhold mellem den menneskelige krop og dens omgivelser. I en sådan forståelse er menneskesindet ikke et produkt af hjernen, men vores levende væsens aktivitet. En aktivitet, der integrerer hjernen som del af kroppens daglige funktion. Fuchs argumenterer for, at processerne i at leve og i at opleve er intimt forbundne – og derfor er det ikke hjernen, men må altid være mennesket, der føler, tænker og handler. “I en tid, hvor vores forståelse af sindet domineres af neurovidenskaben, og hvor vi i stor udstrækning behandler sindets lidelser med psykofarmakologi, er Thomas Fuchs’ bog ‘Hjernens økologi’ en af de vigtigste, du kan læse. Fuchs afviser på ingen måde de neurovidenskabelige landvindinger, men hans bog sætter hjernen i relation til både kroppen og den økologi, som livet leves i. Han viser, at psyken ikke er i hjernen, men at hjernen er sindets organ, der formidler det levende menneskes relationer til verden. Vi kunne ikke være noget uden vores hjerner, men vi er ikke desto mindre langt mere end vores hjerner. Hjernens økologi er en nuanceret, klog og vigtig bog.” Svend Brinkmann, professor i psykologi, Aalborg Universitet“Intet mindre end fremragende … Fuchs trækker i sit formidable og meget velskrevne værk på evolutionær biologi og antropologi, dynamisk systemteori, psykologi, kulturstudier, filosofi, sprogvidenskab og social neurovidenskab.”Steen Napper Larsen, lektor, DPU
