This clip from the "Five Ways to Save the World" details a cheap, simple, and low-risk way to compensate for global warming.
If the reflectivity of clouds could be increased slightly, sufficient sunlight would be reflected to compensate for any future release of CO2 into the atmosphere. (09:37)

The Origin of Teflon
The slipperiest stuff known to man, Teflon has made a tremendous impact on the world. Invented by accident in 1938, it has gone on to become a substance in all kinds of household items. Created by mistake, PTFE (poly-tetra-fluoro-ethylene) is a long chain carbon polymer surrounded by fluoride atoms. The fluoride atoms fully enclose the carbon chain so that it can't react with other molecules. It wasn't until 1944 that the name "Teflon" became trademarked. Dr. Kiki gives us the skinny in this

Science Extreme - Making it Rain...on Purpose
"The Chinese government promised and delivered a rain-free opening ceremony to the delight of thousands in attendance and millions watching around the world. During the rainy season how did they do this? Simple: They seeded storm clouds with iodide before they blew into the capital city causing the rain to fall long before they reached Bejing.

Exchanges in the New World
Columbus’s famed voyage in 1492 joined two very different worlds. For thousands of years, Europeans and Native Americans lived completely separate lives, unaware of the others’ existence. When Columbus stepped onto the rocky soil of San Salvador, he started a historic chain of events that affected the lives of millions of people on both sides of the Atlantic.
Columbus and later explorers discovered a land unlike anything they had experienced. They encountered neatly patterned park-like

Charming Snakes- Cobras in the Dark
Cobras are one of the most poisonous snakes in the world. Their most
distinctive feature is their hooded head which they raise to intimidate
prey as it spreading their hood makes them look larger.
Cobras usually eat rodents, eggs, and frogs; but they also eat other
snakes such as rat snakes. Their venom is a neurotoxin and when injected
into prey, it paralyses the animal by shutting down the function of the
nervous system, which ultimately leads to cardiac
The Eucharist (part 1 of 3)
In many ways, Our Lord, is calling us to worship and receive Him in the Eucharist. He speaks this desire in many ways: through the Pope and the Magisterium of the Church, in the Bible (Jn. 6), through his Blessed Mother in approved Marian apparitions, through the testimonies of Saints and Martyrs, through Eucharistic miracles, through Church approved messages given by Jesus by Divine Revelation, through our souls who long for Jesus in Communion, and through our suffering world which is in much n
Population Growth- Baby Boom
After World War II had drawn to a close, the United States experienced unprecedented population growth that to this day has shaped the social and political landscape of the country, and changed how and where many Americans live. Known as the "baby boom," this population expansion took place between the years 1946 and 1964, with the peak occurring in 1957. The elevated birthrate, unparalleled in American history, added more than 50 million babies by the end of the 1950s. (Video is narrated with s
Fractals: On the Defense
Though many colleagues initially scorned Mandelbrot's work, his mesmerizing fractal images launched a popular culture fad. More importantly, his book The Fractal Geometry of Nature explained how his ideas could be applied in the real world. Mandelbrot's ideas inspire an ever-increasing number of applications, including the fractal antenna.
