Next stop - the moon! Jeremy Hansen stops by our studio to chat about how he's prepping to be the first Canadian to go to the moon.Plus:Santa's reindeer may be losing their antlers –– and climate change could be the culpritReindeer are the only animal in the deer family where the females also grow antlers, and they typically have a full rack over the wintertime and drop them in June when they give birth. University of Guelph PhD student Allegra Love was monitoring reindeer on Fogo Island in Newfoundland, when she made a surprising discovery that female reindeer are losing and growing their antlers much earlier than usual. This can put more stress on the animal during a crucial part of their pregnancy, and the researchers think this could eventually lead to the reindeer losing their antlers altogether. The work was published in the journal Ecosphere.Pterosaur brains reveal clues about why these mighty fliers took to the skiesFlight has only evolved among vertebrates three times — in bats, birds, and first in pterosaurs. How pterosaurs first took to the skies was always a mystery to scientists, until the discovery of a fossilized 230-million year old pterosaur relative in Brazil. An international team, including Ohio University professor Lawrence Witmer, used an MRI for detailed analysis of the fossilized skull, to pinpoint the miniscule brain changes that happened as the animal developed the capacity to fly. The research was published in the journal Current Biology.Scientists are using AI to find life in 3 billion year old rocksEarth's earliest signs of life are often incredibly difficult to detect. An international team of researchers have developed a new tool that uses AI to find “whispers” of life locked inside ancient rocks. Using this tool, the researchers, including astrobiologist Michael Wong from Carnegie Science, were able to detect fresh chemical evidence of life in rocks that are 3.3 billion years old. This tool can not only be used to explore the origins of life here on Earth, but also on Mars and other planetary bodies. The work was published in the journal PNAS.

Get 20% off at timeline.com/vanessa In today's episode, Vanessa sits down with Dr. Howard, the lead author of a brand-new PNAS study that is challenging one of the most widely accepted ideas in human metabolism. For years, many scientists believed that our bodies operate within a fixed daily calorie "budget," and that after a certain point, increasing activity doesn't increase total calorie burn. But Dr. Howard's new research suggests the story may be far more dynamic — and far more empowering — than we ever realized. OneSkin is powered by the breakthrough peptide OS-01, the first ingredient proven to reduce skin's biological age. I use the OS-01 Face and Eye formulas daily—they've transformed my skin's smoothness, firmness, and glow. Visit oneskin.co/VANESSA and use code VANESSA for 15% off your first purchase. This conversation explores what this new evidence could mean for: How we think about calorie burn Why activity matters (in ways we didn't fully understand before) The role of fueling, recovery, and energy balance What actually drives fat loss and body recomposition How to train smarter, not harder Mentioned in this episode: Physical activity is directly associated with total energy expenditure without evidence of constraint or compensation — published in Proceedings of the National Academy of Sciences (PNAS).  Read the full study here → PNAS DOI 10.1073/pnas.2519626122 NEW!

Welcome to The Sleep Edit, the podcast that helps tired kids and parents sleep better. Each week, Dr. Craig Canapari and sleep consultant Arielle Greenleaf break down evidence-based strategies you can actually use. Why are nap transitions so confusing—and why do they so often derail nights? In Part 2 of our napping series, Craig and Arielle dig into the real-world challenges families face when moving from 3→2 naps, 2→1 nap, and eventually dropping naps entirely. Using concrete examples, sleep-need math, and practical troubleshooting, this episode explains exactly what to look for and how to navigate every transition with less stress. You'll learn • How to know when it's time to drop a nap • The signs of a nap transition vs. a temporary “nap strike” • Why total 24-hour sleep matters more than wake-window charts • What typical daytime sleep looks like for infants and toddlers • The sleep math behind transitions (high vs. low sleep-need kids) • How daycare schedules can derail naps—and what parents can control • Strategies for capping naps, shifting schedules, and preventing bedtime battles • When early morning awakenings actually signal too much daytime sleep Chapters 00:00:01 — Welcome & Episode Setup 00:01:07 — The 3→2 Nap Transition: When It Starts 00:02:48 — Biology of Sleep Drive & Late Naps 00:03:43 — Why Late Bedtimes Are So Common Now 00:04:59 — How Total Sleep Needs Shape Nap Schedules 00:06:32 — Wake Windows vs. Real Sleep Need 00:07:52 — Consolidated Naps & Nap Length Targets 00:09:41 — How to Use the Third Nap as a Bridge 00:11:06 — Example: Designing a 13.5-hour Sleep Day 00:12:59 — Signs It's Time to Drop From 3→2 Naps 00:14:45 — Why Transitions Are Messy (and Normal) 00:15:56 — The 2→1 Nap Transition: Age & Signs 00:17:46 — Developmental Milestones That Disrupt Naps 00:19:06 — Case Example: Drew (13 Months) 00:20:57 — How to Start the 2→1 Transition Step-by-Step 00:22:54 — Shifting Nap Timing & Early Bedtime Strategy 00:23:56 — Tracking Sleep: Apps vs. Diaries 00:24:53 — Why Smart Monitors Often Mislead Parents 00:26:50 — When Nights Get Worse Because of Nap Issues 00:27:59 — The 1→0 Transition: What Truly Signals Readiness 00:29:18 — Daycare Nap Challenges & Parent Options 00:31:56 — Capping Naps to Protect Nighttime Sleep 00:33:30 — Nap Strikes vs. True Transitions 00:36:06 — Early Morning Awakenings & Too Much Day Sleep 00:38:30 — Final Thoughts & The Greenleaf Windows Links Napping spectacular episode 1 CIO episode of the Sleep Edit Dr. Canapari's article on Le Pause Sleep training Period of purple crying Dr. Canapari's article on napping Dr. Canapari's article on sleep needs in children Dr. Canapari articles on the science of why children stop napping Arielle's website References Paruthi, S., Brooks, L.

The 2024 KFF Women's Health Survey found that one in three women reported being ignored or disbelieved by a healthcare provider, and data from the PNAS (2024) study showed that clinicians consistently rated women's pain as less severe than men's for the same symptoms. Together, these studies tell a sobering truth — gender bias is not anecdotal, it's structural.

Pendant des décennies, on a cru qu'en multipliant les compliments, on aidait les enfants à s'épanouir. « Tu es le meilleur ! », « Tu es génial ! » — autant de phrases censées nourrir la confiance. Mais selon une recherche conjointe de l'Université d'État de l'Ohio et de l'Université d'Amsterdam, publiée dans la revue PNAS, ces compliments exagérés sont en réalité un piège. Loin de renforcer l'estime de soi, ils peuvent créer des enfants égocentriques, voire manipulateurs, incapables plus tard de relations équilibrées.Tout commence souvent avec de bonnes intentions. Un parent veut encourager son enfant, surtout s'il le sent fragile ou timide. Alors il multiplie les louanges. Mais lorsqu'elles deviennent disproportionnées — quand on félicite non pas l'effort, mais la personne elle-même, en la présentant comme exceptionnelle —, le cerveau de l'enfant apprend une leçon bien différente : pour être aimé, il faut être extraordinaire. Ce n'est plus la curiosité ni la persévérance qui comptent, mais l'image que l'on renvoie.Les chercheurs ont observé que ces enfants finissent par éviter les situations où ils risquent d'échouer. L'échec, pour eux, n'est pas une étape normale de l'apprentissage, mais une menace pour l'identité flatteuse qu'on leur a imposée. Ils préfèrent donc ne pas essayer plutôt que de risquer d'être « démasqués ». Et pour continuer à mériter l'admiration, ils développent des stratégies sociales subtiles : séduire, manipuler, attirer l'attention, parfois rabaisser les autres pour se sentir supérieurs.Peu à peu, l'enfant devient dépendant du regard extérieur. Il mesure sa valeur à travers l'approbation d'autrui. Dans ce processus, une chose s'étiole : l'empathie. S'il se vit comme le centre du monde, les besoins des autres perdent de l'importance. Il ne cherche plus à comprendre, mais à convaincre ; plus à échanger, mais à briller. Ce type d'éducation, en apparence bienveillante, prépare sans le vouloir des adultes narcissiques, fragiles sous leur assurance, et incapables de tisser des liens sincères.Les chercheurs insistent : la clé n'est pas de bannir les compliments, mais de les orienter autrement. Il faut cesser de dire « Tu es incroyable » et apprendre à dire « Tu as bien travaillé ». Féliciter l'effort plutôt que le talent, reconnaître les progrès plutôt que la perfection. C'est ainsi que l'enfant apprend que la valeur ne se joue pas dans le regard des autres, mais dans l'action, la persévérance et la relation à autrui. En somme, c'est en apprenant à échouer qu'on apprend aussi à aimer. Hébergé par Acast. Visitez acast.com/privacy pour plus d'informations.

I denne episoden tar vi deg med inn i et favoritthack – rebounding, eller trening på minitrampoline! Dette er noe vi gjør hver eneste dag, både hjemme og sammen med deltakerne på Core Balance. Her deler vi hvorfor denne lekne og enkle treningsformen er så effektiv for lymfehelse, energi, humør og avgiftning – og hvordan du kan komme i gang. Gjennom episoden lærer du hvordan lymfen er kroppens rensesystem, hvorfor den trenger bevegelse for å flyte, og hvorfor noen minutters hopping kan gjøre mer for energien din enn en lang løpetur.Dette lærer du i episoden:Hva lymfesystemet er og hvorfor det er helt avgjørende for immunforsvar og energi?Hvordan trampolinetrening kan øke lymfesirkulasjonen opptil tre ganger mer enn vanlig gange?Hva NASA fant ut om hvorfor rebounding er den mest effektive treningsformen for astronauter?Hvordan opp og ned-bevegelsen fungerer som en “indre dusj” som skyller kroppen ren for avfallsstoffer?Hvorfor rebounding er skånsomt for leddene, men likevel styrker muskler, balanse og kondisjon?Den mentale effekten, hvorfor hopping gjør deg lykkeligere, roligere og mer tilstede?Hvordan du kan starte med bare 5–10 minutter om dagen?Hva slags trampoline du bør velge, og hvorfor bungee-strikker er gullstandarden?Hvordan rebounding faktisk kan styrke bekkenbunnen, ikke svekke den?Hvorfor dette er en biohack for alle, uansett alder, form og nivå?Studier: Mukherjee, A. et al., Entrainment of Lymphatic Contraction to Oscillatory Flow, 2019.

Summary: Ants are some of the most misunderstood animals on Earth. Join Kiersten as she begins a new series about these fascinating insects.   For my hearing impaired followers, a complete transcript of this podcast follows the show notes on Podbean   Show Notes:  “Tales from the Ant World” by Edward O. Wilson “Adventures Among Ants,” by Mark W. Moffett “In Search of Ant Ancestors,” by Ted R. Schultz, Proc Natl Acad Sci U S A. 2000 Dec 5;97(26):14028–14029. doi: 10.1073/pnas.011513798 “The abundance, biomass, and distribution of ants on Earth,” by Patrick Schultheiss, Sabine S Nooten, Runxi Wang, and Benoit Gurnard. PNAS, 119 (40) e2201550119, https://doi.org/10.1073/pnas.2201550119 Music written and performed by Katherine Camp   Transcript (Piano music plays) Kiersten - Welcome to Ten Things I Like About… This is a podcast about misunderstood or unknown creatures in nature. Some we'll find right out side our doors and some are continents away but all are fascinating.  My name is Kiersten and I have a Master's Degree in Animal Behavior and did my thesis on the breeding behavior of the Tri-colored bat. I was a zookeeper for many years and have worked with all sorts of animals from Aba Aba fish to tigers to ravens to domesticated dogs and so many more in between. Many of those years were spent in education programs and the most important lesson I learned was that the more information someone has about a particular animal the less they fear them. The less they fear them the more they crave information about them and before you know it you've become an advocate for that misunderstood animal. This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won't regret it. This is the beginning of a new series about a misunderstood animal that every one of us has encountered. Ants. Ants are one of the most misunderstood animals on the planet but they are so fascinating and very successful. In this series we are going to find out what makes them tick. The first thing I like about ants is their origins. As I begin this series I actually have a red, angry fire ant bite on my thumb. The irony is not lost on me that I am about to embark on a ten episode series dedicated to lauding the amazing attributes of ants to lure you into loving them while I have an itchy, painful welt from an ant bite on my thumb. These animals are truly fascinating so I bet I can get you to fall in love with them despite the nasty bites we've probably all experienced. Let's get started from the beginning shall we? The classification of ants is as follows: Kingdom Animalia (Animals) Phylum Arthropoda (Arthropods): invertebrate animals that have a segmented body and jointed appendages Subphylum Hexapoda (Hexapods): a six-legged arthropod  Class Insecta  (Insects) Order Hymenoptera (Ants, Bees, Wasps and Sawflies) Superfamily Formicoidea (Ants) Family Formicidae (Ants) The scientific names will vary based on species. When did ants first appear on the planet?  They have been on the planet between 100 -150 million years ago. The specific timing has been hotly debated for many years until and amber sample was found by some rock hounds in 1966. This sample was discovered in Cliffwood Beach, New Jersey in the United States. It seemed an unlikely place to find what scientists needed to determine the origins of ants and it took twenty more years after the initial discovery to clarify whether this sample was of an ant or not. In 1986, it was confirmed to be the amber fossil of an ant solidifying the origins of ants in the mid-Cretaceous period, 90-94 million years ago. By the mid-Eocene period, approximately 50 million years ago, ants had achieved their current level of abundance. How many ants are on the planet today? In the summer of 2018, Edward O. Wilson, one of, if not the, foremost experts in the study of ants said in his book, Tales from the Ant World, that there are 15,438 species of ants in the world that have been recognized and given a Latinized name. Edward O. Wilson described 450 of known species of ants so I think we can take his word for when he says he's fairly certain there are approximately 25,000 species in existence today. A study published in 2022, says 15,700 species of ants have been identified. The numbers do see to be going up! The ant taxonomists working at Harvard University which has the world's largest collection of ants believe the figure to be between 25,000 to 30,000 different species of ants. To sum it up, there are a lot of ant species out there! Ants actually make up two-thirds of all insect life on Earth. We don't know have many individual ants are walking around on the Earth at this very moment, but it is in the billions possibly trillions. They are found on every single continent except Antarctica, but as soon as they figure out how to live in snow and ice, they'll be there too. They inhabit every habitat the planet has to offer from forests of all kinds, mountains ranges, deserts, prairies, and wetlands. There are even ants that scavenge for food underwater. They live underground, in the branches of trees, and inside caves. The eat seeds, fungi, animal protein, and insect protein. They are hunters, farmers, ranchers, and enslavers. They have one matriarch and live for the good of the colony. Ants are unbelievably complicated life forms and I can't wait to take you on a journey you won't forget. Thanks for joining me for the first episode of ants. My first favorite thing about this misunderstood insect is their origins. If you're enjoying this podcast please recommend me to friends and family and take a moment to give me a rating on whatever platform your listening. It will help me reach more listeners and give the animals I talk about an even better chance at change.  Join me next we for another exciting episode about ants.        (Piano Music plays)  This has been an episode of Ten Things I like About with Kiersten and Company. Original music written and performed by Katherine Camp, piano extraordinaire.

5—6—3—4—3—1—7—2In the first episode under our new podcast name (it's now the Science Fictions podcast!), we ask whatever happened to all those games that claimed to tell you your “brain age”—games that turned into a whole scientific literature on brain training. We discuss: the still-unresolved question of whether training one specific cognitive ability makes you generally smarter; seemingly endless contrasting meta-analyses; and the small matter of what brain training might tell us about the nature of intelligence.(If you can repeat the list of numbers from the top in reverse order then you have the brain of a 25-year-old. If you're 25 or younger, then I don't know what to tell you.)We're now an official part of the Works in Progress podcast world. You can find their other podcasts, including Hard Drugs, the one we talked about on today's episode (about the remarkable development of a drug for HIV), at podcast.worksinprogress.co.

What if our memories weren't fixed, but flexible? And what if the key to understanding fear, emotion, and consciousness lies in how the brain constantly reshapes experience?In this episode of Mind-Body Solution, Dr Tevin Naidu speaks with Prof Daniela Schiller, a world-renowned neuroscientist, and director of the Laboratory of Affective Neuroscience at Mount Sinai. Prof Schiller's groundbreaking work explores how we form, change, and even reimagine emotional memories, from the neuroscience of fear to the dynamic nature of consciousness and identity. Together, we dive into:- How fear memories are formed in the brain- Why emotional responses are flexible, not hardwired- The ethics of modifying traumatic memories- Social navigation: how the brain maps human relationships- The Human Affectome: a bold framework linking emotion and consciousness- Can machines ever be conscious? Free will, probabilities, and neuroscience- Memory as liberation: how to live with multiple stories of the selfProf Schiller is not only a world-leading neuroscientist with work published in Nature, Neuron, Nature Neuroscience, and PNAS, she's also a Fulbright Fellow, Kavli Frontiers of Science Fellow, two-time Moth StorySLAM winner, and drummer for the rock band "The Amygdaloids".TIMESTAMPS:(0:00) – Introduction: Daniela Schiller on the Science of Emotion & Memory(0:39) – From Animal Models to Human Fear Studies: Schiller's Journey(2:00) – What Happens in the Brain When a Fear Memory is Formed?(3:15) – Flexibility of Emotional Responses: Why Fear Is Not Hardwired(4:51) – Computational Psychiatry & the Brain as an Algorithmic System(6:00) – From Circuits to Consciousness: Can Neuroscience Explain Subjective Experience?(7:11) – The Human Affectome: A Framework Linking Emotion and Consciousness(9:13) – What Is Consciousness?

Inflammation is the body's natural way of healing, but when it becomes chronic and hidden, it quietly drives many of today's most common health problems—heart disease, diabetes, dementia, cancer, autoimmune conditions, and more. Unlike the redness and swelling from a cut or sprain, this “silent inflammation” often goes unnoticed while slowly damaging tissues and speeding up aging. Modern life fuels the fire: processed foods, food additives, pollution, plastics, chronic stress, too much sitting, and poor sleep. The good news is inflammation can be calmed by simple daily choices—eating colorful whole foods like berries, leafy greens, beans, nuts, seeds, and omega-3 rich fish; adding herbs and spices like turmeric and cumin; moving regularly; practicing relaxation; and repairing gut health. Even small shifts, like climbing stairs, eating within a shorter window, or reducing sugar, can make a big difference. By lowering inflammation, the body finds balance again, opening the door to more energy, resilience, and healthy aging. In this episode, I discuss, along with Dr. Shilpa Ravella and Dr. David Furman, why it's important to be aware of systemic inflammation and how to address it. Dr. Ravella is a gastroenterologist and Assistant Professor of Medicine at Columbia University Medical Center. She is the author of A Silent Fire: The Story of Inflammation, Diet & Disease, which investigates inflammation—the hidden force at the heart of modern disease. Her writing has appeared in The Atlantic, New York Magazine, The Wall Street Journal, TIME, Slate, Discover, and USA Today, among other publications.  Dr. David Furman is Associate Professor and Director of the Bioinformatics Core at the Buck Institute for Research on Aging, as well as the Director of the Stanford 1000 Immunomes Project. He obtained his doctoral degree in immunology from the School of Medicine, University of Buenos Aires, Argentina, for his work on cancer immune-surveillance. During his postdoctoral training at the Stanford School of Medicine, Dr. Furman focused on the application of advanced analytics to study the aging of the immune system in humans.

In our last standard episode, we talked about retraction—removing papers from the scientific literature. Well, it turns out there's an awful lot of retraction to do, in large part due to paper mills. These are fraudulent enterprises that take money from nefarious scientists to put their name on fake scientific papers, and get them published in whatever journal will accept them. Sadly, paper mill papers are now rife. In this solo episode of The Studies Show (Tom is away at a wedding), Stuart talks through a new paper showing just how badly these paper mills have poisoned the scientific literature.Show notes* The new PNAS paper using various techniques to examine coordinated attempts at scientific fraud* A response from PLOS* The Retraction Watch article on ARDA* A few interesting recent articles on paper mills* The Nature News article on the universities with the most retractions* AI versus paper millsCreditsThe Studies Show is produced by Julian Mayers at Yada Yada Productions.

Fungal infections and disease have long been overlooked in terms of healthcare burden, with poor diagnostics and limited options for treatment and management. In 2022, the WHO published its first Fungal Priority Pathogens List as an effort to establish a global prioritised framework that addresses unmet research and development needs in fungal disease and antifungal resistance, as well as guides public health action [1]. In this episode of Communicable, Angela Huttner and Josh Nosanchuk invite Hatim Sati (WHO), the project lead in creating this list, and Dimitrios Kontoyiannis (MD Anderson Cancer Center, Houston, Texas), a clinician researcher studying fungal diagnostics and antifungal discovery, for a candid discussion on the making of and relevance of such a list. Apart from reviewing the fungal pathogens, the conversation also covers limitations of the list, what to expect for the next iteration, contextualising the list in one's local region, and the impact the list has had already on research funding and public awareness.This episode was edited by Kathryn Hostettler and peer reviewed by Andrisa Xhaxha from Elbasan, Albania. ReferencesWHO fungal priority pathogens list to guide research, development and public health action.

Recognizing a familiar voice is one of the brain's earliest social feats. But what are the brain circuits that let a newborn pick out mom in a crowded nursery? How do they change as kids turn toward friends and the wider world? And what are we learning about why this instinct fails to develop in the autistic brain?This week, host Nicholas Weiler joins Stanford neuroscientist Dan Abrams on the quest to understand the neural “hub” that links our brains' hearing centers to the networks that tag voices as rewarding, social, and worth our attention.

The adaptability of fungi to warmer temperatures is an obvious consequence of climate change. Perhaps less obvious is the role climate change has played on fungal pathogens emerging as a global health concern. While humans are mostly protected from fungal infections by our immune system and body temperature, a warming global climate could subvert the status quo. Some fungi are already adapted to warmer temperatures and causing invasive acute infections in humans: Candidozyma auris, Cryptococcus neoformans, and Aspergillus fumigatus, to name a few.  In this episode of Communicable, Angela Huttner and Josh Nosanchuk invite Arturo Casadevall, a Bloomberg Distinguished Professor at Johns Hopkins and this year's recipient of ESCMID's Excellence in Science Award, to discuss the world of fungi and their pathogenic potential in a warming world. Other topics include how to prepare for their emergence as a health threat, how fungi can be harnessed for applications that can benefit us, and ultimately answering the question Casadevall himself posed in the title of his recently published book, What if fungi win?This episode was edited by Kathryn Hostettler and peer reviewed by Robin Aerts of University Hospital Antwerp, Belgium.  References1.        Casadevall, A with Desmon S.

All the colours of the rainbow, plus oneResearchers have fired lasers directly into the eye to stimulate photoreceptors, and produce the perception of a colour that does not exist in nature. They describe it as a “supersaturated teal,” and hope the technique will allow them to better understand colour vision and perhaps lead to treatments for vision problems. Austin Roorda has been developing this technology using mirrors, lasers and optical devices. He is a professor of Optometry and Vision Science at University of California, Berkeley. The study was published in the journal Science Advances.Following in the footsteps of an ancient ankylosaurPaleontologists have found fossil footprints of an armoured dinosaur in the Canadian Rockies that fill in a critical gap in the fossil record. The footprints belonged to a club-tailed ankylosaur about five to six metres long, and are the first evidence of this type of dinosaur living in North America in a period known as the middle Cretaceous. The research was led by Victoria Arbour, curator of paleontology at the Royal B.C. Museum, and published in the journal Vertebrate Paleontology.Did the Neanderthals die from sunburn?Neanderthals disappeared 40,000 years ago, and new research suggests this corresponds to a period of weakness in the Earth's magnetic field that allowed an increase in the solar radiation reaching the surface. Researchers think they have evidence that modern humans were able to protect themselves from the sun better than Neanderthals could, and this might have contributed to the Neanderthal extinction. Raven Garvey is an anthropologist at the University of Michigan. Her team's research was published in the journal Science. Cloudy with a chance of ammonia mushballsNew observations and models of activity within Jupiter's stormy atmosphere is giving a weather report for the giant planet, and it's pretty extreme. Most interestingly, researchers predict conditions that could lead to violent lightning storms producing softball sized frozen ammonia “mushballs” that would rain through the upper atmosphere. The research was led by Chris Moeckel, a planetary scientist and aerospace engineer at the University of California-Berkeley Space Sciences Laboratory, and was published in the journal Science Advances.Shattering heat records: climate change is turning out to be worse than expectedIn the last few years, we've seen global temperatures rising faster, with more extreme localized heatwaves, than climate models predicted. Climate scientists are trying to understand this by investigating the underlying factors behind these heating trends. Richard Allan, from the University of Reading in the U.K., was expecting a larger than normal rise in global temperatures due to natural fluctuations, but global temperatures in 2023 and 2024 were much higher than expected. Their recent study in the journal Environmental Research Letters found a growing imbalance in the earth's heat system, with increasingly more heat coming in than leaving, in large part due to changes we've seen in global cloud cover.This global heating is not happening evenly around the world. Kai Kornhuber, from the International Institute for Applied Systems Analysis in Austria and Columbia Climate School in New York, found regional hotspots that are experiencing unexpected extreme heat, likely due to a combination of factors. That study is in the journal PNAS. 

Most iguanas are indigenous to the Americas. So how did the Fijian species end up on the island, nearly 5000 miles away in the South Pacific? According to a new study in the journal PNAS, it was probably via raft ... that is, on clump of floating trees. And this rafting hypothesis isn't entirely unprecedented. After hurricanes Luis and Marilyn hit the Caribbean in the 1990s, researchers found that a group of iguanas had floated over 180 miles away from Guadeloupe to the territory of Anguilla.
