The Known Universe by AMNH
 
06:31
The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world's most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History. The new film, created by the Museum, is part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010.

Human Population Through Time
 
06:25
It took 200,000 years for our human population to reach 1 billion—and only 200 years to reach 7 billion. But growth has begun slowing, as women have fewer babies on average. When will our global population peak? And how can we minimize our impact on Earth’s resources, even as we approach 11 billion?

Meet the Titanosaur
 
03:00
Measuring 122 feet, the Museum's new exhibit, The Titanosaur, is big--so big that its head extends outside of the Museum's fourth-floor gallery where it is now on permanent display. This species of dinosaur, a giant herbivore that belongs to a group known as titanosaurs, is so new that it has not yet been formally named by the paleontologists who discovered it. The Titanosaur lived in the forests of today’s Patagonia about 100 to 95 million years ago, during the Late Cretaceous period, and weighed 70 tons. It is one of the largest dinosaurs ever discovered. The fossils on which this cast is based were excavated in the Patagonian desert region of Argentina by a team from the Museo Paleontologico Egidio Feruglio led by José Luis Carballido and Diego Pol, who received his Ph.D. at the American Museum of Natural History. In this video, Dr. Mark Norell, chair and Macaulay Curator in the Division of Paleontology, describes how such a massive animal could have supported its own weight and why the Titanosaur is one of the more spectacular finds during what he describes as "the golden age of paleontology."

Neil deGrasse Tyson On Manhattanhenge
 
03:50
**Note: The dates in this video apply to 2013. For 2018, Mahattanhenge occurs on Tuesday, May 29 at 8:13 PM EDT (half Sun on grid), Wednesday, May 30 at 8:12 PM EDT (full Sun on grid), Thursday, July 12 at 8:20 PM EDT (full Sun on grid), and Friday, July 13 at 8:21 PM EDT (half Sun on grid). Four evenings a year, the brick, steel, and asphalt of Manhattan's cityscape take part in a unique alignment of metropolis and cosmos. The rays of the setting sun align perfectly with Manhattan's street grid—framed by skyscrapers and creating a breathtaking wash of illumination along the cross streets. Frederick P. Rose Hayden Planetarium Director Neil deGrasse Tyson first noted the phenomenon more than a decade ago and coined the term "Manhattanhenge." In this video, Tyson discusses how he came up with the name and what future anthropologists might make of New York City's serendipitous alignment with the sun. To discover the best spots and times for 2018 Manhattanhenge viewing, and get more details about the phenomenon from Neil deGrasse Tyson, visit: http://www.amnh.org/our-research/hayden-planetarium/resources/manhattanhenge
Tornado Alley IMAX Trailer
 
01:53
Traversing the "severe weather capital of the world," Tornado Alley documents two unprecedented missions to encounter one of Earth's most awe-inspiring events: the birth of a tornado. This science adventure reveals the beauty and the power of some of our planet's most extreme—and least understood—weather phenomena. Opens July 4, 2011 at American Museum of Natural History.
Science Bulletins: Attachment Theory—Understanding the Essential Bond
 
08:22
In 1958, psychologist John Bowlby pioneered "attachment theory," the idea that the early bond between parent and child is critical to a child's emotional development. Since then, scientists have discovered that insecure attachment during formative years can significantly stress both the developing brain and body, resulting in long-term psychological and physical ailments. For example, low levels of attachment security have been linked to diminished levels of cortisol, a steroidal hormone released in response to stress that is critical in reducing inflammation in the body. Watch the latest Human Feature from the Museum's Science Bulletins program to see how recent studies are using cortisol levels as a marker to determine the success of early intervention in building stronger attachments between struggling parents and children. Visitors to AMNH may view the video in the Hall of Human Origins until January 2, 2012. Science Bulletins is a production of the National Center for Science Literacy, Education, and Technology (NCSLET), part of the Department of Education at the American Museum of Natural History.

Preserving Lonesome George
 
04:35
Museum scientists and a master taxidermist describe the painstaking process—part art, part science--of preserving Lonesome George, the famous Pinta Island tortoise who died in 2012 in the Galapagos Islands. As the last known survivor of the tortoise species Chelonoidis abingdoni, Lonesome George served as a global icon of conservation—and a reminder of the urgent need to address ever-increasing extinctions. After a limited time on view at the Museum Lonesome George returns to Ecuador as part of that nation’s patrimony. The Lonesome George exhibit is on view in the Astor Turret on the Museum's fourth floor from September 19, 2014, through January 4, 2015.

Science Bulletins: Mapping Emotions in the Body
 
02:24
Feelings are often associated with physical reactions: terror can send chills down your spine, and love can leave you weak in the knees. A recent study has linked specific emotions to physical sensations. Researchers tested emotional responses in hundreds of subjects and then created maps identifying locations in the body where emotions cause physical changes. Science Bulletins is a production of the National Center for Science Literacy, Education, and Technology (NCSLET), part of the Department of Education at the American Museum of Natural History.

Neil deGrasse Tyson on Finding Krypton
 
06:53
During a roundtable discussion with journalists, Hayden Planetarium Director Neil deGrasse Tyson explains how he helped Superman find his home planet of Krypton. Tyson appears as a character in the recent DC Comics' ACTION COMICS #14, "Star Light, Star Bright." In real life, he consulted a star index and found a real star that supported the backstory of the comic. The red dwarf star designated for having the ability to support a Krypton-like planet is located in the constellation Corvus 27.1 light years from Earth. The star, designated LHS 2520, possesses a red, highly turbulent surface, somewhat cooler and smaller than the Sun. To find it in the night's sky, amateur astronomers and Superman fans can follow these coordinates: J2000 Right Ascension: 12 hours 10 minutes 5.77 seconds Declination: -15 degrees 4 minutes 17.9 seconds Proper Motion: 0.76 arcseconds per year, along 172.94 degrees from due north Dr. Tyson has a well-documented history applying science to entertainment in order to make the subject accessible and exciting to the public. He is the Director of Hayden Planetarium at the American Museum of Natural History, which since its founding in 1935 has served as the premier conduit between the frontier of cosmic discovery and the public's appreciation of it. Tyson also recently made headlines by getting film director, James Cameron, to alter the night's sky as seen in The Titanic due to inaccuracies. The adjustment was made and can be seen in the re-release of Titanic 3-D. Tyson noted, "As a native of Metropolis, I was delighted to help Superman, who has done so much for my city over all these years. And it's clear that if he weren't a superhero he would have made quite an astrophysicist."

Science Bulletins: Keeling's Curve – The Story of CO2
 
03:38
As the leading greenhouse gas, carbon dioxide is one of the atmosphere’s most closely watched ingredients. The scrutiny began in 1958, when a young geochemist named Charles Keeling began regularly measuring CO2 atop a massive Hawaiian volcano—and discovered some intriguing patterns.

Rare Spider Silk on Exhibit at AMNH
 
03:29
A spectacular and extremely rare textile, woven from golden-colored silk thread produced by more than one million spiders in Madagascar is now on display at the American Museum of Natural History in the Grand Gallery. Drawing on the legacy of a French missionary, Jacob Paul Camboué, this contemporary textile measures 11 feet by 4 feet and took four years to make using a painstaking technique. Hear from Dr. Ian Tattersall, Curator, Division of Anthropology at AMNH, as well as Nicholas Godley, co-creator and owner of the silk along with his partner Simon Peers as they discuss this rare work.

The Amazing Shapes of Ammonites
 
03:14
Happy Cephalopod Week! When you think of an ammonite, you probably think of a spiral-shelled sea creature. But in fact, this was just one of the many shapes that ammonites took. Museum Curator Neil Landman explains how this array of shapes once confounded evolutionary biologists, and why this variety is actually a good example of how evolution works. Cephalopod Week is the annual celebration of all things tentacled.

Remote Reconnaissance of Another Solar System
 
02:15
This visualization, produced using the Hayden Planetarium's Digital Universe--the most comprehensive and scientifically accurate, three-dimensional map of the known universe-- shows where the star HR 8799 is in relation to our solar system. Recently, a team of researchers led by the American Museum of Natural History used a suite of high-tech instrumentation and software called Project 1640 (www.amnh.org/project1640) to collect the first chemical fingerprints, or spectra, of the four red exoplanets orbiting this star. This visualization also shows other stars that are known to harbor planetary systems (stars with blue circles around them). HR 8799's system, which is 128 light years away from Earth, is one of only a couple of these stars that have been imaged, and the only one for which spectroscopy of all the planets has been obtained. Over the next three years, the team will survey many of these other stars in the same manner in which they studied HR 8799.

Science Bulletins: Bilingual Brain 'Switch' Found
 
02:02
A recent study led by University College London neuroscientist Cathy Price reveals how the human brain is uniquely adapted to manage multiple languages. Language is processed in various regions of the left cerebral hemisphere. Previous studies using functional magnetic resonance imaging (fMRI) data showed that bilingual people activate the same general brain areas no matter what language they use. But Price's new experimental method, which involved measuring brain activity after showing subjects word pairs with similar meaning, showed increased activity in a specific region—the left caudate—when speakers shifted from one language to the other. The new fMRI data clarifies why bilinguals with damaged left caudates involuntarily switch languages when speaking. The study is an important step in understanding how humans can speak more than one language, a unique ability of our complex brain.

How is a nautilus different from a squid?
 
04:08
Happy Cephalopod Week! The weird and mysterious nautilus is a cephalopod, just like octopuses, squids, and cuttlefish. But how similar are these shelled critters to their relatives? Curator and paleontologist Neil Landman gives seven ways that the nautilus is unique among its evolutionary neighbors. #CephalopodWeek #Nautilus #Squid #Explainer #DeepSea #OceanLife *** Subscribe to our channel: http://www.youtube.com/user/AMNHorg?sub_confirmation=1 Check out our full video catalog: http://www.youtube.com/user/AMNHorg Facebook: ‪http://fb.com/naturalhistory ‬‬‬‬‬‬‬‬‬‬‬‬‬‬ Twitter: ‪http://twitter.com/amnh ‬‬‬‬‬‬‬‬‬‬‬‬‬‬ Tumblr: ‪http://amnhnyc.tumblr.com/‬‬‬‬‬‬‬‬‬‬‬‬‬‬ Instagram: ‪http://instagram.com/amnh‬‬‬‬‬‬‬‬‬‬‬‬‬‬ This video and all media incorporated herein (including text, images, and audio) are the property of the American Museum of Natural History or its licensors, all rights reserved.

The Science Behind De-extinction
 
05:49
Fossils of dinosaurs, mammoths, and saber-toothed cats on display on the Museum's fourth floor are impressive and imposing specimens of animals that once roamed the Earth, then vanished during mass extinctions at the end of the Cretaceous and Pleistocene eras. Elsewhere in the Museum, visitors can see species whose more recent extinctions were caused by human activity, from the Dodo in the Hall of Biodiversity to the Passenger Pigeon, one of North America's most plentiful birds until the early 1900s, featured in the Hall of New York City Birds. In the not-too-distant future, scientists expect that technological breakthroughs—and availability of genetic data from specimens of extinct species—will provide ways to revive vanished species. In this video, Museum Curator Ross MacPhee discusses the science and ethical considerations of "de-extinction."
Science Bulletins: Autistic Brains Show Visual Dominance
 
02:02
After examining brain-mapping studies of hundreds of autistic people, scientists from the University of Montreal in Canada and Massachusetts General Hospital in Boston have found distinct patterns that seem to underlie autistics' remarkable visual abilities.
Inside the Collections: Pacific Northwest Coast Peoples
 
04:26
While highlights from the Museum's collection of artifacts from the Pacific Northwest Coast are on display in the Hall of Northwest Coast Indians, more than 13,000 objects are kept in storage in the Division of Anthropology. Join Curator of North American Ethnology Peter Whitely as he leads a tour of the collections, which includes a giant Kwakwka'wakw whale mask, a Chilkat blanket with three different interpretations of its abstract symbolism, and a Haida/Tsimshian raven rattle. Many of the artifacts in the Division of Anthropology's Pacific Northwest Coast Collection were amassed during a series of expeditions in the late 19th and early 20th centuries. The most scientifically important of these expeditions, the Jesup North Pacific Expedition led by anthropologist Franz Boas between 1897 and 1902, collected more than 4,000 objects. Visitors can also find a number of whale-related artifacts from the Anthropology collections in the Museum's special exhibition, "Whales: Giants of the Deep," now open through January 5, 2014.

Transformation: Dinosaurs to Birds
 
03:27
This spellbinding animation from the Museum’s new exhibition “Dinosaurs Among Us” traces the evolutionary transition from dinosaurs to birds. Learn more about “Dinosaurs Among Us”: http://www.amnh.org/exhibitions/dinosaurs-among-us Based on recent scientific research that examines fossils using new technologies, the transformation story unfolds as low-polygonal silhouettes of dinosaurs morph from ground-dwelling animals into flight-capable birds. The mass extinction that erased most dinosaurs 65 million years ago left a few bird lineages unscathed. Within only 15 million years all of our familiar bird groups were flourishing. These extraordinary living dinosaurs provide a vivid link to the ancient past. The Museum’s new exhibition, “Dinosaurs Among Us,” explores the continuities between living dinosaurs—birds—and their extinct ancestors, showcasing remarkable new evidence for what scientists now call one of the best-documented evolutionary transitions in the history of life.

Niles Eldredge: Trilobites and Punctuated Equilibria
 
04:46
In the late 1960s, Curator Emeritus Niles Eldredge was a graduate student with a passion for trilobite eyes. He had been taught to expect slow and steady change between the specimens of these Devonian arthropods he collected for his dissertation. Only his trilobites were doing one of two things: staying the same, or evolving in leaps. Several years later, Eldredge, along with co-author Stephen Jay Gould, turned his observations into a theory known as “punctuated equilibria”: the idea that species stay relatively the same, or at equilibrium, throughout the fossil record save for rare bursts of evolutionary change. A former Chairman and Curator of Paleontology at the American Museum of Natural History, Eldredge remains at the hub of evolutionary discussion and debate, as well as one of the world's experts on trilobites, specializing in mid-Paleozoic phacopids. He has also analyzed the relationship between global extinctions of the geologic past and the present-day biodiversity crisis, as well as the general relationship between extinction and evolution.

Why Did Pterosaurs Have Crests?
 
01:57
The incredible diversity of pterosaurs is perhaps best expressed in one of the prehistoric flying reptile's most intriguing and mysterious features: the head crest. Pterosaur crests are thought to have been fairly ubiquitous, appearing in many groups of pterosaurs from the Triassic (252--201 million years ago) through the Jurassic (201--145 million years ago) and Cretaceous (145--66 million years ago) periods. Why did pterosaurs have crests? There are competing theories, chief among them that crests serve as a form of species identification. Other possibilities include a role in sexual selection, heat regulation, as a rudder in flight, or as a keel in the water, stabilizing the reptile as it dove or skimmed for food. Without living descendants for comparison and because pterosaur fossils are so rare, it's impossible to say for sure. Researchers would have to find thousands more fossils in different growth stages to answer the question. Pterosaurs: Flight in the Age of Dinosaurs is on view from April 5, 2014, through January 4, 2015. Learn more about the exhibition at http://www.amnh.org/pterosaurs.

Recoloring the Animals in the Dioramas
 
05:09
Fluorescent lighting, embraced by diorama artists in the 1940s for its cool, blue-sky effect, eventually caused animal skins to fade, bleaching dark fur blond. To restore scientific accuracy, conservators searched for a just-right colorant that was light-stable, reversible or retreatable, and that wouldn't clump, mat, or bind the fur. The solution was a series of carefully mixed shades of a commercial dye. The restored Hall of North American Mammals reopened October 2012.

Inside the Collections: Paleontology and the Big Bone Room
 
02:31
Paleontology Collections Manager Carl Mehling gives us a behind-the-scenes tour of the Big Bone Room, which houses some of the largest items in the Paleontology collection. Its holdings include one of the largest complete limb bones in the world: the 650-pound thigh bone of the long-necked, plant-eating dinosaur Camarasaurus. Visitors will be able to see this spectacular specimen in the upcoming major exhibition The World's Largest Dinosaurs (April 16, 2011-January 2, 2012), which explores the amazing anatomy of a uniquely super-sized group of dinosaurs, the sauropods. More than 3 million specimens make up the Museum's world-class paleontology collections, and only a small fraction can be displayed at any given time. In fact, only 0.02 percent of the Museum's vertebrate paleontology specimens are on view; the rest are stored behind the scenes, where they continue to be studied by Museum scientists and their colleagues.
How Do We Know Where to Look for Dinosaur Fossils?
 
01:54
First, dinosaur fossils are found almost exclusively in sedimentary rocks, in other words, rocks that form when sand, silt, mud, and organic material settle out of water or air to form layers that are then compacted into rock. So in looking for dinosaur fossils, one must find outcrops of sedimentary rocks. Second, no dinosaurs are known to have lived in the ocean, where most sedimentary rocks form. Instead, one must look in sedimentary rocks that were deposited on the continents, primarily by rivers and streams or in lakes into which the streams emptied. Occasionally, dinosaur fossils are also found in sedimentary rocks representing ancient, desert sand dunes and their associated habitats. Third, the sedimentary rocks must have been formed or deposited during the Mesozoic Era, the geologic time period when nonavian dinosaurs lived. Finally, it's best to search in regions where little vegetation covers the surface of the ground, so that any fossil fragments weathering out of the sedimentary rock layers can be more easily seen. These regions of barren ridges and ravines are often called badlands. In order to find appropriate, Mesozoic, sedimentary rock layers, paleontologists often use geologic maps, which document the kinds of rock layers of different geologic ages that are exposed on the surface. Once appropriate rock layers are found, the search for dinosaur fossils can begin with a reasonable hope of finding the kinds of dinosaurs one is searching for. But commonly, other kinds of fossils are serendipitously discovered during the search. This video is part of a series, "Dinosaurs Explained," produced by the American Museum of Natural History. In the series, Museum paleontologists answer the most frequently asked questions about dinosaurs. To watch the videos, go to www.amnh.org/explore/amnh-tv.

How Were Pterosaurs Adapted for Flight?
 
03:30
Pterosaurs were the first animals after insects to evolve powered flight—not just leaping or gliding, but flapping their wings to generate lift and travel through the air. They evolved into dozens of species: Some were as large as an F-16 fighter jet, and others as small as a paper airplane. Pterosaurs flew with their forelimbs: Their long, tapering wings evolved from the same body part as our arms. As pterosaurs' arm and hand bones evolved for flying, they lengthened, and the bones of one finger—the equivalent of our ring finger—became extraordinarily long. Like the mast on a ship, these bones supported the wing surface, a thin flap of skin that was shaped like a sail. Although many animals can glide through the air, pterosaurs, birds and bats are the only vertebrates that have evolved to fly by flapping their wings. All three groups descended from animals that lived on the ground, and their wings evolved in a similar way: their forelimbs gradually became long, bladelike and aerodynamic. Although they have much in common, pterosaurs, birds and bats developed the ability to fly independently. Their wings evolved along different paths, and the difference can be seen in their structure. Pterosaurs: Flight in the Age of Dinosaurs is on view from April 5, 2014, through January 4, 2015. Learn more about the exhibition at http://www.amnh.org/pterosaurs.

Science Bulletins: The Cosmic Microwave Background—A New View from the South Pole
 
07:57
The icy South Pole desert is a harsh and desolate landscape in which few life-forms can flourish. But the extreme cold and isolation are perfect for astronomical observations. Taking advantage of the severe conditions, scientists are using the new South Pole Telescope—the largest ever deployed in Antarctica—to observe the oldest light in the Universe, the cosmic microwave background (CMB).

Updating the "Moon Shadow" in Wolf Diorama
 
03:31
When new energy-efficient lights were installed in the Wolf diorama, they created new shadows that weren't consistent with the scene—a moonlit December night on the southern shore of Gunflint Lake in northern Minnesota. Here, Museum artist Stephen C. Quinn adds various pigments to the "snow" to re-create the illusion of shadows that would result from the Moon casting its eerie blue light on the wolves and surrounding trees.

How can scientists study a faraway black hole that emits no light? By observing its quasar. As objects get pulled onto the accretion disk orbiting a supermassive black hole, friction creates a bright light known as a quasar. In this video, researchers use a “galaxy-sized lens” to analyze light from a distant quasar—revealing a supermassive black hole with a truly voracious appetite.

Warning Colors in the Animal World
 
02:02
It's not easy being green... But it's awesome being yellow. Or red. Or orange, black, and white. In the natural world, many different animal species use bright colors and patterns to advertise the fact that they would make a horrible snack. At the American Museum of Natural History's exhibition, THE POWER OF POISON, you'll learn how certain colors may signal that an animal is poisonous or venomous. These warning colors are good for both predators and prey and can be seen in a variety of species, ranging from moths to mammals, across the animal kingdom. Visit http://www.amnh.org/poison for more information. Major funding for the exhibition has been provided by the LILA WALLACE - READER'S DIGEST ENDOWMENT FUND.

Science Bulletins: Deadly Larvae Lure Predators
 
01:53
Amphibians that try to feed on the larvae of the Epomis beetle will find that they've bitten off more than they can chew. Rather than avoiding its predators, the larva lures them closer and then attacks, latching on tight with its hooked jaws and feeding parasitically. The latest Bio Bulletin from the Museum's Science Bulletins program highlights this unprecedented role reversal in the animal kingdom. View the story in AMNH's Hall of Biodiversity until November 14, 2011 or online.

02:30
In the first of a new series of behind-the-scenes looks at the collections at the American Museum of Natural History, Melanie Stiassny, Axelrod Research Curator in the Department of Ichthyology, takes us through the Museum's vast collection of fishes. The Department of Ichthyology, one of the four departments within the Museum's Division of Vertebrate Zoology, houses a collection that comprises more than 2 million specimens from around the world, with a special focus on African, Australian, Central American, Chinese, and Malagasy fresh water fishes as well as Bahamian and Gulf of Mexican shore fishes. The department's three curators, as well as postdoctoral fellows, students and staff, regularly conduct fieldwork to add to these collections. Stiassny has carried out studies throughout the world's tropical waters to research the evolution, behavior, and conservation of fishes and has played an active role in raising public awareness of the biodiversity and conservation crisis. Her current projects include an exploration, sponsored by the National Science Foundation, of the freshwater fishes and mussels of the Congo. Produced/edited by James Sims.

Documenting an Ancient Kingdom In Sudan
 
05:47
In November 2011, Museum Curator Alex de Voogt, Postdoctoral Fellow Vincent Francigny, and Research Associate William Harcourt-Smith set out on a Constantine S. Niarchos Expedition to Sudan. Over the course of two weeks, the team traveled some 2,000 kilometers and visited about 20 archaeological sites dating from the ancient kingdom of Meroë. Meroë was an independent kingdom of Nubia, centered in the north of Sudan and contemporaneous with Greek and Roman domination of the Mediterranean world. While Meroites were influenced by their Egyptian neighbors, they had a distinct political state, writing system, and religion. Archaeologists have only been able to translate a few Meroitic texts, so researchers must use other clues from the past to learn about this ancient civilization. One of the 2011 Niarchos expedition's main goals was to document depictions of animals at archaeological sites. The animal representations they detailed in the field—ranging from elephants to frogs—will be compiled with images from artifacts in existing museum collections to create a "bestiary" for Meroë. This bestiary will be an organized catalog of animals, giving insight into how different species were used and ultimately leading to further research questions about religion, environment, and other subjects. The expedition team also investigated other topics, including paleoanthropology, board games, and zootherapy—the use of animals in medicine. This 2011 Constantine S. Niarchos Expedition was generously supported by the Stavros Niarchos Foundation. ARCHIVE IMAGES COURTESY OF Steve F. E. Cameron COSV R.

Preparing Dinosaur Fossils Inside AMNH
 
03:07
Fossil preparators are highly skilled technicians who restore the naturally fractured bones and teeth of fossil to the original state, somewhat like art conservators restore damaged paintings and sculptures. When fossils arrive from the field, they are encased in plaster jackets, and the rock, or matrix, which was deposited around the fossils. Fossil preparation involves cutting open the plaster jacket and removing this matrix surrounding the fossil. The matrix may be soft and crumbly when the sand or mud is poorly cemented together, or it can be extremely hard when the sediments are well-cemented. Accordingly, a wide variety of tools is required to remove the matrix and stabilize the fossil. Commonly, dental tools are used to carefully pick away sediment near the bone, along with custom-made needles composed of carbide steel. Preparators carefully select the materials used to strengthen or repair specimens. Adhesives, glues, and fillers must stand the test of time and not become brittle or discolored, just like the materials used to conserve works of art. The types of materials used are recorded in order to aid future preparators if further preparation or repair is required. Watch as Justy Alicea, a senior preparator at the American Museum of Natural History, works on a specimen and then gives a tour of the Museum's fossil preparation lab.

Hiroshi Sugimoto: Four Decades of Photographing Dioramas
 
03:34
The photographer Hiroshi Sugimoto has visited to the Museum four times in the past four decades to shoot his "Dioramas" series, which focuses on habitat displays to explore the distinction between the real and the fictive. What initially surprised Sugimoto about the series was that his photos looked utterly real--as if he were photographing on location, and not in front of a three-dimensional representation of a real location. Part of this effect can be credited to Sugimoto's talent as a photographer, but the effect wouldn't be possible without the skill of the Museum's diorama artists, who blended science and nature to create the illusion of reality. Using the latest technology, they constructed the foreground, taxidermy, and painted background of a diorama to reflect that of the original site. Not lost on Sugimoto is the fact that when Museum preparators made collecting trips to diorama sites, they documented the area with photographs, which they referred to when they went back to the Museum and brought the dioramas to life. "Now I'm re-photographing the diorama, based on the photography," the artist said. "So many layers of transformation--that's very conceptually interesting." During a 2012 shoot of the Olympic Forest diorama in the Hall of North American Forests, Sugimoto explained why he keeps coming back to the Museum. "I have my ideas and visions of what nature should look like. So I'm using this diorama to represent my idealistic visions of nature." Known as "Windows on Nature," the Museum's habitat dioramas are recognized internationally as premier examples of the fusion of art and science. The lifelike displays were created to educate the public about nature and science and also engender feelings of wonder for the natural world. For his latest round of photographs, the artist used his trademark 8 x 10 large-format camera to explore the theme of lost nature, or what the earth would look like if human civilization vanished. The first photographs from the "Dioramas" series, shot in 1976, brought Sugimoto to acclaim. "Dioramas" continues to gain an audience today with recent exhibitions at the J. Paul Getty Museum in Los Angeles and the Pace Gallery in New York. Dioramas seen in this video (in order of appearance):

Scientists are becoming increasingly aware of how life experiences can change both the physical structure and the function of the brain. Since a discovery in the mid-1990's that the hippocampus—a brain region important for memory—is reduced in size in many combat veterans, research has exploded over how traumatic events can affect different regions of the brain. This story highlights recent work by Victor Carrion's team at the Stanford University Early Life Stress Research Program that shows how adverse events in childhood can make an early mark on brain function.

How are Pterosaur Names Pronounced?
 
02:17
Everyone knows how to say "Tyrannosaurus rex," but pterosaur names are not as familiar as those of their dinosaur cousins. Even the word "pterosaur" (TER-o-soar) can trip up readers with its silent "p" (the word originates from the Greek pteron, for wing, and sauros, for lizard). Now, you can brush up on tongue-twisting pterosaur genus names, from Jeholopterus to Quetzalcoatlus, with a pronunciation guide featuring students from the Museum's education programs. Pterosaurs are named according to a set of rules called the International Code of Zoological Nomenclature, with scientific names including the genus and species. The first person to describe a pterosaur assigns the animal its name, which is often derived from Greek or Latin words or references the place where the specimen was collected or unusual anatomical characteristics. The species Quetzalcoatlus northropi, discovered in southwestern Texas, was named after Quetzalcoatl, a Mexican god of the air, and the industrialist Jack Northrop, known for developing a stealth aircraft called the flying wing. Pterosaurs: Flight in the Age of Dinosaurs is on view from April 5, 2014, through January 4, 2015. Learn more about the exhibition at http://www.amnh.org/pterosaurs.
