All living things are made of cells. In the human body, these highly efficient units are protected by layer upon layer of defense against icky invaders like the cold virus. Shannon Stiles takes a journey into the cell, introducing the microscopic arsenal of weapons and warriors that play a role in the battle for your health.

Rodalquilarite.

Rodalquilarite

Locality: Wendy open pit: Tambo Mine, Coquimbo region, Chile.

Rodalquilarite is a rare secondary mineral formed in the zone of oxidation of tellurium-bearing precious metal deposits. It is found in only three places worldwide: Spain (type locality), Chile and the United States (Arizona). Rodalquilarite forms stout, green, prismatic crystals; commonly in crusts.

How we conquered the deadly smallpox virus - Simona Zompi

View full lesson: http://ed.ted.com/lessons/how-we-conq...

For 10,000 years, humanity suffered from the scourge of smallpox. The virus killed almost a third of its victims within two weeks and left survivors horribly scarred. But Simona Zompi commends the brave souls -- a Buddhist nun, a boy, a cow, a dairymaid and physician Edward Jenner -- who first stopped the spread of this disastrous disease, to make us smallpox-free today.

↓ More info and sources below ↓

As more and more parents are choosing not to vaccinate their children or are vaccinating them later, diseases like measles are making a comeback. Are vaccines safe? How do vaccines work? Why do some people claim there is a link between vaccines and autism? This week we look at why are people afraid of something that has saved so many lives, and look at the history and science of vaccines.

Inicio del verano 2015

El verano de 2015 comenzará el domingo 21 de junio a la 18h 38m hora oficial peninsular, a las 17h 38m en Canarias. Esta estación durará 93 días y 15 horas, y terminará el 23 de septiembre con el comienzo del otoño.

El día 13 de septiembre se producirá un eclipse parcial de Sol que no será visible en España. En cuanto a los planetas, Venus empezará el verano muy brillante y siendo visible después de la puesta de Sol. Terminará la estación siendo visible antes del amanecer. Marte empezará a verse antes del amanecer a finales de julio, y Jupiter se verá inicialmente tras la puesta de Sol, y a primeros de septiembre pasará a verse antes del amanecer. Saturno se verá después de la puesta de Sol durante todo el verano.

La tradicional lluvia de estrellas de las Perseidas sucederá hacia el 12 de agosto y su observación será favorable por coincidir con la Luna en fase cercana a la Luna nueva

ECLIPSES Y FENÓMENOS RELACIONADOS

A lo largo del verano habrá un eclipse parcial de Sol que no será visible en España. Sucederá el día 13 de septiembre y será visible en la Antártida y África meridional.

OBSERVACIÓN NOCTURNA DEL CIELO EN VERANO

En toda época del año hay algún fenómeno astronómico de interés, predicho (como son los eclipses) o no (como los cometas nuevos). Suele ser preferible realizar las observaciones en fechas cercanas a la luna nueva (16 de julio, 14 de agosto y 13 de septiembre), salvo cuando se pretende observar la propia Luna.

Luna llena.

La primera luna llena del verano se dará el 2 de julio, dándose las siguientes 29 o 30 días después. En este verano se darán otras dos lunas llenas: 31 de julio y 29 de agosto.

Visibilidad de los planetas.

En la primera parte del verano serán visibles al atardecer Venus (muy brillante), Júpiter y Saturno, en la segunda parte soló será visible Saturno. En el cielo matutino será visible Marte desde primeros de agosto, Venus desde mediados del mismo mes y Júpiter desde primeros de septiembre.

Lluvias de meteoros.

Si no se dispone de ningún telescopio, se pueden observar las lluvias de meteoros que se producen ocasionalmente. Las dos más intensas durante el verano son las delta Acuáridas, cuyo máximo ritmo se da alrededor del 30 de julio, y la más famosa del verano, la de Las Perseidas, cuyo máximo se da alrededor del 12 de agosto.

Constelaciones.

En cuanto a las agrupaciones ficticias de estrellas conocidas como constelaciones, alrededor de la estrella Polar se verán a lo largo de la noche Casiopea, Cefeo, el Cisne, el Dragón y las dos Osas. De Este a Sur a Oeste se verán Pegaso, el Aguila, la Coronal Boreal y la Cabellera de Berenice. Cerca del horizonte se verán a lo largo de la noche algunas de las constelaciones zodiacales, de la Virgen a Acuario, esta última ya cerca del amanecer. Entre las estrellas más brillantes visibles en esta época destacan las que constituyen el "triángulo del verano": Altair (en el Aguila), Deneb (en el Cisne) y Vega (en la Lira).

Observaciones con prismáticos o pequeños telescopios.

Con grandes prismáticos o un pequeño telescopio, dotados de un filtro lunar adecuado, se puede observar el relieve de la Luna. Para tener una buena visión de él conviene ir observándolo noche tras noche mientras va creciendo la iluminación de la Luna, pues así se ven aparecer nuevos accidentes orográficos. Cuando la noche es más oscura por haber luna nueva, se puede intentar ver nebulosas de emisión, como la Laguna, Omega o la Trífida, y nebulosas planetarias como el Anillo en la constelación de Lira o las Pesas en la Raposa. Con prismáticos también se pueden ver las lunas más brillantes de Júpiter (cuando es visible) y se puede hacer un recorrido por la franja estrellada que constituye la Vía Láctea.

Measles Explained — Vaccinate or Not?

Everybody is talking about Measles – but what does the virus actually do in the body? Is it really so harmful that you need a vaccination? We go deep into the body of an infected person and see what Measles does and how the immune system reacts to it!


Videos, explaining things. Like evolution, time, space, global energy or our existence in this strange universe. 
We are a team of designers, journalists and musicians who want to make science look beautiful. Because it is beautiful.

Measles Explained — Do You Really Need To Vaccinate?

The Immune System Explained I – Bacteria Infection.

Every second of your life you are under attack. Bacteria, viruses, spores and more living stuff wants to enter your body and use its resources for itself. The immune system is a powerful army of cells that fights like a T-Rex on speed and sacrifices itself for your survival. Without it you would die in no time. This sounds simple but the reality is complex, beautiful and just awesome. An animation of the immune system.

We are thinking of making an App for tablets out of this video. Would you like that? Did you think the visual system we developed worked? Feedback is much appreciated!

Anatomical Body Painting on a Pregnant Woman Shows a Developing Fetus

Anatomical Body Painting on a Pregnant Woman Shows a Developing Fetus

Dutch photographer Leonie Versantvoort and bodypaint artist Marieke Crone collaborated on Bellypaint, a photo project featuring an anatomical painting on the body of a pregnant woman. The body painting—while not perfectly anatomically correct—artfully shows what the inside of the mother’s body may look like as the fetus develops.
