Vietnam: Journeys of Body, Mind, and Spirit
This Web site, created to complement the Vietnam: Journeys of Body, Mind, and Spirit exhibit, includes the following sections: Introduction is an overview of the incredible diversity of Vietnam's people and landscapes; Journeys Through Time and Space provides a look at Vietnam today and a time-line of this ancient country's history; Journeys of Gods, Families and Ancestors considers the importance of lunar New Year and the ancestral altar; Journeys of People and Goods examines how international
It Takes All Kinds to Make a World
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, marine biologist Melanie Stiassny introduces kids to biodiversity in the ocean. The article contains three engaging, kid-friendly sections: Diversity of Life on Earth, which has an overview of six major groups of life on Earth and challenges kids to determine the correct group for nine different life forms, including blue-green alga, spiny lobster, red mangrove, and white marlin.
Milstein Hall of Ocean Life
This Web site, created to complement the Hall of Ocean Life, looks at the cradle of life for our planet, along with its key to our future. It includes the following sections: Dioramas is an in-depth look at the Hall of Ocean Life's dioramas. They are: Andros Coral Reef, Diving Birds, Diving for Pearls, Polar Bear, Sargasso Sea, Walrus, West Indian Manatee, Northern Elephant Seal, Northern Sea Lion, Harbor Seal, Dolphin and Tuna, Sea Otter, Tiger Shark, and Sperm Whale and Giant Squid.

Earth Rotation from Galileo Imagery: 3600 x Real-Time
This animation is one in a series created to show an accurate representation of the Earths rotation at different temporal resolutions. The animation is created from images taken by the Galileo spacecraft during a close pass of the Earth on December 11-12, 1990. The animations range from real-time, in which no rotation can be perceived, to 3600 times real-time, in which both the Earths rotation and cloud motion can bee seen. The series also includes an animation in which the Earths rotation has b

Molecular Classification - Prof. Chris Man (Part 2)
Recent advances in genomic and proteomic technologies have revolutionized our way of classifying diseases. These high-throughput technologies allow the development of powerful and multivariate classifiers to distinguish different diseases or tumors based on their molecular profiles. Molecular classification provides a new way to distinguish histologically similar but molecularly different types of tumors, and hence improves tumor diagnosis and prognosis. In this course, we introduce major concep
Multipolar representation of protein structure
Background
That the structure determines the function of proteins is a central paradigm in biology. However, protein functions are more directly related to cooperative effects at the residue and multi-residue scales. As such, current representations based on atomic coordinates can be considered inadequate. Bridging the gap between atomic-level structure and overall protein-level functionality requires parameterizations of the protein structure (and other physicochemical properties) in a quasi-co
Methylphenidate Decreased the Amount of Glucose Needed by the Brain to Perform a Cognitive Task
The use of stimulants (methylphenidate and amphetamine) as cognitive enhancers by the general public is increasing and is controversial. It is still unclear how they work or why they improve performance in some individuals but impair it in others. To test the hypothesis that stimulants enhance signal to noise ratio of neuronal activity and thereby reduce cerebral activity by increasing efficiency, we measured the effects of methylphenidate on brain glucose utilization in healthy adults. We measu
Drawing Shadows to Stone: Photographing North Pacific Peoples
This Web site, created to complement an American Museum of Natural History exhibition, takes a look at an anthropological expedition to record the people and cultures of the North Pacific.
Paradise Redefined: Part 2
A journey to a coral reef chain hidden in the Central Pacific forces scientists to revisit the definition of a pristine environment. Part Two.
Obesity is Socially Contagious
Are your friends making you fat? Or keeping you slender? According to new research from Harvard and the University of California, San Diego, the short answer on both counts is "yes.”
NetMHCpan, a Method for Quantitative Predictions of Peptide Binding to Any HLA-A and -B Locus Protei
Background
Binding of peptides to Major Histocompatibility Complex (MHC) molecules is the single most selective step in the recognition of pathogens by the cellular immune system. The human MHC class I system (HLA-I) is extremely polymorphic. The number of registered HLA-I molecules has now surpassed 1500. Characterizing the specificity of each separately would be a major undertaking.
Principal Findings
Here, we have drawn on a large database of known peptide-HLA-I interactions to develop a
Orchidaceae Morphology: Oncidium cultivar
Orchid morphology of Oncidium. Structures labeled include: petals; sepals; callus; column; column wings; stigma; pollinia and anther cap. Includes a dissection that removes the anther cap to expose the pollinia.
Open genius: strumento per una scienza libera
The presentation of the researcher Andrea Gaggioli about a new way to finance the scientific research: crowd funding. Le nuove tecnologie partecipative possono trasformare radicalmente la ricerca scientifica. Strumenti emergenti quali il crowdsourcing e il crowdfunding possono contribuire a rendendere la scienza un'impresa più aperta, trasparente e democratica. Questo intervento video esplora questi strumenti e introduce Open*Genius, una piattaforma 2.0 per aiutare i ricercatori a trovare le ri

Pericardial pathology 900 years ago: A study and translations from an Arabic medical textbook
This is a study and translation of the section on pericarditis in Al Taisir book written by the Muslim physician Ibn Zuhr (Avenzoar) who lived and practiced in Eshbeelia (nowadays Seville, Andalusia,Spain) between 1091-1162 AD. Ibn Zuhr described the serous type of pericarditis as well as the pathological findings in fibrinous pericarditis. His description of the latter may also fit with the picture of chronic fibrous pericarditis. He also described acute purulent pericarditis and involvement of
Photonic Dipole Contours of Ferrofluid Hele-Shaw Cell (Two Magnet Non-Pole Video)
This investigation describes and demonstrates a novel technique for the visualization of magnetic fields. Two ferrofluid Hele-Shaw cells have been constructed to facilitate the imaging of magnetic field lines. We deduce that magnetically induced photonic band gap arrays similar to electrostatic liquid crystal operation are responsible for the photographed images and seek to mathematically prove the images are of exact dipole nature. This is the two magnet version with the non-pole sides mostly f
