Diego Velázquez - La Fragua de Vulcano
Descripción escrita por Arte Historia.
Pintado por Velázquez hacia 1630 en su primer viaje a Italia, fue posteriormente comprado por Felipe IV en 1634. El tema elegido está inspirado en las Metamorfosis de Ovidio: Apolo se acerca a la fragua de Vulcano para contarle la infidelidad de su esposa, Venus, con Marte. (2:19)
Diego Velázquez - San Antonio Abad y San Pablo Ermitaño
Descripción por Arte Historia.
Esta es una de las pocas obras religiosas que realizó Velázquez a lo
largo de su carrera. Su destino sería una de las numerosas ermitas que había en el Jardín del Buen Retiro, probablemente la de San Pablo, por lo que se suele fechar hacia 1633.Cuenta la historia de la visita de San Antonio Abad a San Pablo, el primer ermitaño. (2:17)
Diego Velázquez - El bufón Don Juan de Austria
Este retrato también estaba inventariado en el Palacio del Buen Retiro en 1701, formando pareja con el de Cristobal de Castañeda y Pernia, fechándose ambos hacia 1636. Sin duda no estamos ante la figura del hijo natural de Felipe II, sino ante un bufón que interpretaba el papel del héroe de la batalla de Lepanto. (2:33)
Diego Velázquez - Vista del jardín de la Villa Médicis en Roma
Descripción escrita por Arte Historia.
Velázquez realizaría esta preciosa escena casi con total seguridad entre 1649 y 1650, durante su segunda estancia en Roma, junto a su compañera llamada El mediodía, aunque no existe acuerdo al respecto. Se trata de una obra tomada directamente del natural, interesándose el maestro por dar una impresión de la luz en un momento determinado del día, por lo que recibe el sobrenombre d
Diego Velázquez - El príncipe Baltasar Carlos de caza
Descripción escrita por Arte Historia.
El príncipe Baltasar Carlos era la esperanza de la monarquía hispánica ya que, a priori, parecía libre de enfermedades congénitas y de taras psicológicas. Pero el joven príncipe fallecería, de forma repentina, cuando contaba con 17 años de edad, víctima de la viruela. Este precioso retrato, en el que le vemos vestido de cazador acompañado por sus perro

Pulitzer Center grantee Micah Albert discusses Kenya's Dandora Municipal Dump Site located in Nairobi, a dump site that serves as a starting point for understanding the growing human rights problems facing the region due to waste management inefficiencies.
Spanning thirty acres of land in Nairobi, the dumping continues at the Dandora Municipal Dump Site at an estimated
Death and Love: The Poetry of Afghanistan's Women

Over 300 members of Mirman Baheer, the Ladies Literary Society, stretch across the provinces of Afghanistan. Women write and recite landai, two-line folk poems that can be funny, sexy, raging or tragic and have traditionally dealt with love and grief. For many women, these poems allow them to express themselves free of social constraints and obligations. 5 out of 100 women in Afghanistan

A Shoutout from Dottie Metcalf-Lindenburger, NASA Astronaut
Have you ever wondered why science, technology, engineering, and math are so important? Think you might want to work for NASA someday? Astronaut Dottie Metcalf-Lindenburger studied geology, taught middle school and flew in space. STEM was important in each of these adventures and continues to play a key role in NASA's exploration of the solar system. Watch this video to find out how cool science, technology, engineering and math can be!
Science Bulletins: Decoding the DNA of Extinct Species
Caves were important refuges for humans and animals that coexisted during the late Pleistocene, the epoch of ice ages that ended 10,000 years ago. These sheltered environments can preserve evidence of extinct biological communities that archaeologists, paleontologists, and geneticists can mine for clues the species' biology, behavior, and evolution. Recently, exceptionally well-preserved bones from European caves have yielded DNA for two Ice Age species, Neanderthals and cave bears. The teams-on
Science Bulletins: Full Gene Set Decoded for Three More People
In June 2000, scientists triumphantly announced they had deciphered the full human genome—the 3.2 billion units of DNA that make up the blueprint for human life. This sequence was a composite of smaller segments of DNA from many individuals, arranged to make one complete strand. Sequencing this genome cost billions of dollars and took more than a decade using the laboratory tools and techniques developed at the time. Since then, faster and cheaper sequencing techniques have been developed. Now
Science Bulletins: Ancient Graves Reveal Family Ties
In 2005, a team of archaeologists unearthed a well-preserved group of 4,600-year-old graves in the agricultural region of Eulau, Germany. People were buried three and four to a grave, an unmistakable stamp of the Corded Ware Culture, the earliest farmers in the region. Yet the intimate arrangement of the burials—some people were facing each other and had arms interlinked—prompted a deeper investigation.
DNA testing revealed that their orientation in death reflected an important connection i
Science Bulletins: Immune "Army" Can Fight HIV
Some people who contract the HIV virus stay healthy for decades. Scientists working towards HIV vaccines seek out these rare patients, who are called elite controllers. A recent study by researchers at the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, reveals one of the mechanisms behind their uncommon ability to ward off AIDS.
Science Bulletins: Mapping "Hobbit" History
The remains of a group of one-meter tall people who lived as recently as 12,000 years ago were found on the Indonesian island of Flores in 2003. Researchers have been examining the fossils ever since, seeking clues to where the Flores people fall on the human family tree and how they became so small. A new analysis by Kieran McNulty of the University of Minnesota and Karen Baab of Stony Brook University adds to growing agreement that these so-called "hobbits" were a distinct species of the Homo
Science Bulletins: Learning vs. Remembering: A Brain Battle ?
Our everyday affairs require many different brain functions that seem to occur simultaneously. Recently, neuroscientists from the University of Amsterdam and Duke University tested the human brain's ability to handle two tasks in quick succession: learning new information and recalling information already learned. Brain scans showed that a "switchboard" region in the frontal lobe seems responsible for fluidly and rapidly shifting between learning and remembering to avoid a bottleneck in our neu
Science Bulletins: Stomach Bacteria Show Early Human Travels
Evolutionary scientists are increasingly turning to an unusual tool to explore ancient human history: bacteria. Some microorganisms, like Helicobacter pylori, take up residence in our stomachs. Since they go where humans go—and undergo genetic changes along the way—they provide a way to track ancient human migration patterns. A study by a team of international researchers, recently published in the journal Science, shows how genetic investigation of H. pylori in modern-day East Asian and Pac
Science Bulletins: New Stem Cell Method Shows Promise
The University of Wisconsin-Madison researchers who turned ordinary skin cells into stem cells in 2007 have cleared a major safety concern of using those cells in research: their risk of cancer. Their previous process used a virus to insert several genes into the DNA of skin cells. The genetic code of these genes naturally reprograms cells to revert to their original stem cell state. There was just one problem—the new stem cells were cancer-prone.
The team's new method uses a different vehicl

Mass murder of Kamenka Jews-part 1
Ilya Boltyanskii, who was born in 1924 in Kamenka and lived there during the war years, recounts how, on May 3, 1942, the Jews living in Kamenka were ordered to assemble at the village square near a pigsty and how the selection of the able-bodied people was then carried out.
