The more carbon dioxide that is released into the atmosphere the warmer the atmosphere becomes. Atmospheric carbon dioxide is now at its highest level in at least three million years, primarily as a result of the burning of fossil fuels.

#Engineers invent transparent coating that cools solar cells to boost efficiency Every time you stroll outside you emit energy into the universe:
Heat from the top of your head radiates into space as infrared light. Now three Stanford engineers have developed a technology that improves on solar panel performance by exploiting this basic phenomenon.
Their invention shunts away the heat generated by a solar cell under sunlight and cools it in a way that allows it to convert more photons into electricity.
The material is transparent to the visible sunlight that powers solar cells, but captures and emits thermal radiation,
"Solar arrays must face the sun to function, even though that heat is detrimental to efficiency, "Fan said."
"Our thermal overlay allows sunlight to pass through, preserving or even enhancing sunlight absorption, but it also cools the cell by radiating the heat out
and improving the cell efficiency.""A cool way to improve solar efficiency In 2014, the same trio of inventors developed an ultrathin material that radiated infrared heat directly back toward space without warming the atmosphere.
They presented that work in Nature, describing it as"radiative cooling "because it shunted thermal energy directly into the deep, cold void of space.
In their new paper, the researchers applied that work to improve solar array performance when the sun is beating down.
The Stanford team tested their technology on a custom-made solar absorber--a device that mimics the properties of a solar cell without producing electricity--covered with a micron-scale pattern designed to maximize the capability to dump heat
in the form of infrared light, into space. Their experiments showed that the overlay allowed visible light to pass through to the solar cells,

"An early evaluation of overall survival from the ongoing METEOR trial has shown a strong trend indicating that survival may be improved in patients receiving cabozantinib compared to standard therapy.

The Universe Is Dying Slowly The most comprehensive assessment of the energy output in the nearby universe reveals that today's produced energy is only about half of
A team of international scientists used several of the world's most powerful telescopes to study the energy of the universe
and concluded that the universe is slowly dying.""We used as many space -and ground-based telescopes as we could get our hands on to measure the energy output of over 200,000 galaxies across as broad a wavelength range as possible,"Galaxy And Mass Assembly (GAMA) team leader Simon Driver,
of the University of Western australia, said in a statement. The astronomers created a video explaining the slow death of the universe to illustrate the discovery.
When the Big bang created the energy of the universe about 13.8 billion years ago, some portion of that energy found itself locked up as mass.
When stars shine they are converting that mass back into energy, as described by Albert Einstein's famous equation E=mc2 (energy=mass x speed of light squared).
From the Big bang to Now in 10 Easy Steps"While most of the energy sloshing around in the universe arose in the aftermath of the Big bang,
additional energy is constantly being generated by stars as they fuse elements like hydrogen and helium together,
"Driver said.""This new energy is absorbed either by dust as it travels through the host galaxy,
or escapes into intergalactic space and travels until it hits something, such as another star, a planet,
or, very occasionally, a telescope mirror.""Astronomers have known that the universe is slowly fading out since the late 1990s.
Using several telescopes on the ground, as well as NASA's orbiting GALEX and WISE and the European space agency's Herschel,
the team found that the energy output is dropping over 21 different wavelengths, making their results the most comprehensive assessment to date of the energy output of the nearby universe."
"The universe will decline from here on in, sliding gently into old age, "Driver said d

#Saltwater lamp could replace dangerous kerosene lights The majority of inhabitants on the Philippines7000 islands do not have access to electricity.

safe light source powered by salt and water, which can last for up to six months when used for eight hours a day.
The SALT lamp which stands for Sustainable Alternative Lighting IS LED an light that makes use of the science behind the Galvanic cell (the basis for batteries) and changes electrolytes to a nontoxic
