¿Qué causa la crisis climática?

Como vimos en el vídeo de la sección anterior, las actividades humanas han comenzado a modificar cada uno de los cuatro componentes que generan el clima de la Tierra:

• la atmósfera (el aire que respiramos);
• la hidrosfera (el agua del planeta);
• la criosfera (las capas de hielo y los glaciares), y
• la biosfera (las plantas y animales del planeta).

Las causas de la crisis climática se superponen en gran medida con las causas conocidas de las pandemias, como la que actualmente estamos en medio. El siguiente video resume muy bien los puntos hechos por la periodista científica Sonia Shah.

Para obtener más información sobre las causas de la crisis climática, eche un vistazo a este sitio web educativo https://climatekids.nasa.gov/menu/big-questions/

Visit NSF.gov/light to learn about the fundamental science and engineering discoveries that make these tools and future technologies possible.

Here’s our story so far: An astronomer at a world-class observatory is last seen burning the midnight optics when he suddenly goes missing. A forensic duo equipped with the latest light-based technologies arrives on the scene to investigate. An infrared temperature sensor and room-mapping lasers provide clues, while evidence is bagged and tracked with barcodes. High-speed communication networks powered by fiber optics allow investigators to transmit their findings and obtain additional information as needed. Finally, a forensic holodeck puts it all together and reveals the fate of the professor…

What Does A Cancer Cell Look Like?

Cells are tiny, but what they can reveal about our health is profound. UCLA's Amy Rowat is investigating the texture and squishiness of cells in our body, which can have a huge impact on treatments for cancer and genetic disorders. She explains the mechanics of a cell and describes the teeny, tiny instruments she's created to study them.

We Are Built To Be Kind.

Greed is good. War is inevitable. Whether in political theory or popular culture, human nature is often portrayed as selfish and power hungry. UC Berkeley psychologist Dacher Keltner challenges this notion of human nature and seeks to better understand why we evolved pro-social emotions like empathy, compassion and gratitude.

We've all heard the phrase 'survival of the fittest', born from the Darwinian theory of natural selection. Keltner adds nuance to this concept by delving deeper into Darwin's idea that sympathy is one of the strongest human instincts — sometimes stronger than self-interest.

Is Sugar in Fruit Different Than Sugar in Soda?

How does the sugar in fruit compare to the sugar in processed foods like soda or cookies?

Everyone loves a sweet treat, but on average, Americans eat nearly 66 pounds of added sugar per person per year. It's easy to exceed the daily recommended sugar intake when a 12 oz soda has about 11 teaspoons of added sugar. But what about the sugar in fruit? Should people be worried about how much fruit they're eating? Dr. Kimber Stanhope, a Nutritional biologist at UC Davis, walks us through the science.

Vida en una gota de agua.Life in a Drop of Water.

Hundreds, even thousands, of fascinating organisms can be found in a single drop of pond water. Most are microscopic in size, and they include bacteria, protozoa, metazoa, diatoms, algae, and many others. Incredible close-up photography features dozens of these amazing life forms, including amoeba, paramecia, euglena, rotifers, water bears, and many more. While these organisms may appear strange, they actually have a lot in common with you and me. Students will learn not only how to identify some of the more common species, but they will also find out how to collect and maintain their own cultures. This program provides an excellent introduction to the study of simple, single-celled and multi-cellular organisms.

What Happens Without Gravity?

The Invisible World

We are all surrounded by microorganisms, they live on us within us and around us, they affect everything we do, yet most people have no idea what they look like. Using the latest technology it is possible to see into this normally invisible world.

Microorganisms: "Microscopic Life: The World of the Invisible"

"A study of the plant and animal life found in a jar of ordinary pond water. Illustrates and explains the difference between microscopic plants and animals; between one-celled and many-celled organisms; the meaning of colonial organization; and the various processes of food-gathering, digestion and reproduction."

http://en.wikipedia.org/wiki/Microscope

A microscope (from the Greek: μικρός, mikrós, "small" and σκοπεῖν, skopeîn, "to look" or "see") is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope.

There are many types of microscopes, the most common and first to be invented is the optical microscope which uses light to image the sample. Other major types of microscopes are the electron microscope (both the transmission electron microscope and the scanning electron microscope) and the various types of scanning probe microscope...

History

The first microscope to be developed was the optical microscope, although the original inventor is not easy to identify. An early microscope was made in 1590 in Middelburg, Netherlands. Two eyeglass makers are variously given credit: Hans Lippershey (who developed an early telescope) and Zacharias Janssen. Giovanni Faber coined the name microscope for Galileo Galilei's compound microscope in 1625 (Galileo had called it the "occhiolino" or "little eye").

Rise of modern light microscopy

The first detailed account of the interior construction of living tissue based on the use of a microscope did not appear until 1644, in Giambattista Odierna's L'occhio della mosca, or The Fly's Eye.

It was not until the 1660s and 1670s that the microscope was used extensively for research in Italy, The Netherlands and England. Marcelo Malpighi in Italy began the analysis of biological structures beginning with the lungs. Robert Hooke's Micrographia had a huge impact, largely because of its impressive illustrations. The greatest contribution came from Antonie van Leeuwenhoek who discovered red blood cells and spermatozoa and helped popularise microscopy as a technique. On 9 October 1676, Van Leeuwenhoek reported the discovery of micro-organisms.

In 1893 August Köhler developed a key technique for sample illumination, Köhler illumination, which is central to modern light microscopy. This method of sample illumination gives rise to extremely even lighting and overcomes many limitations of older techniques of sample illumination. Further developments in sample illumination came from Fritz Zernike in 1953 and George Nomarski 1955 for their development of phase contrast and differential interference contrast illumination which allow imaging of transparent samples...

http://en.wikipedia.org/wiki/Microorg...

A microorganism (from the Greek: μικρός, mikrós, "small" and ὀργανισμός, organismós, "organism"; also spelled micro-organism, micro organism or microörganism) or microbe is a microscopic organism that comprises either a single cell (unicellular), cell clusters, or multicellular relatively complex organisms. The study of microorganisms is called microbiology, a subject that began with Anton van Leeuwenhoek's discovery of microorganisms in 1675, using a microscope of his own design.

Microorganisms are very diverse; they include bacteria, fungi, algae, and protozoa; microscopic plants (green algae); and animals such as rotifers and planarians. Some microbiologists also include viruses, but others consider these as nonliving. Most microorganisms are unicellular (single-celled), but this is not universal, since some multicellular organisms are microscopic, while some unicellular protists and bacteria, like Thiomargarita namibiensis, are macroscopic and visible to the naked eye.

Microorganisms live in all parts of the biosphere where there is liquid water, including soil, hot springs, on the ocean floor, high in the atmosphere and deep inside rocks within the Earth's crust. Microorganisms are critical to nutrient recycling in ecosystems as they act as decomposers. As some microorganisms can fix nitrogen, they are a vital part of the nitrogen cycle, and recent studies indicate that airborne microbes may play a role in precipitation and weather...

Is time travel possible? - Colin Stuart

Time travel is a staple of science fiction stories, but is it actually possible? It turns out nature does allow a way of bending time, an exciting possibility suggested by Albert Einstein when he discovered special relativity over one hundred years ago. Colin Stuart imagines where (or, when) this fascinating phenomenon, time dilation, may one day take us.
