Journey by Starlight

NIGHT

This award winning blog looks fascinating.

“Journey by Starlight” is the untold story of Albert Einstein’s imaginary journey across the universe.

“This is the story of a great journey that started with a great thought. One day in 1895 a boy looked into a mirror and wondered what the universe would look like if he could travel on a beam of light. That sixteen year old boy was Albert Einstein and that one thought started him on the road to discover his Theory of Relativity.”

Honey prevents wound infections.

NIGHT

Earlier I mentioned how honey doesn’t spoil. You never see fungus on top of a jar of honey. It has even been found unspoiled after 2000 years.

It therefore seems reasonable to assume it has antibacterial properties and may be useful in treating wound infection.

This seems to be the case.

Below is a link to a 1 minute podcast.

MORNING

The New York times runs a fascinating blog……..

“By 2050 or so, the world population is expected to reach nine billion, essentially adding two Chinas to the number of people alive today. Those billions will be seeking food, water and other resources on a planet where, scientists say, humans are already shaping climate and the web of life. In Dot Earth, reporter Andrew C. Revkin examines efforts to balance human affairs with the planet’s limits. Supported in part by a John Simon Guggenheim Fellowship, Mr. Revkin tracks relevant news from suburbia to Siberia, and conducts an interactive exploration of trends and ideas with readers and experts.”

MORNING

Maybe oranges might become a source of fuel.

“But the biofuel revolution continues to spur innovation and researchers around the world are uncovering alternatives to corn and sugarcane from which to produce ethanol. In Mexico, the newest discovery is ethanol derived from orange peel, which a group of students from the University of Guadalajara’s science and engineering division happened upon while researching essential oils……..”

Antioxidants

NIGHT

Antioxidants can bind free radicals in the body. This is good because free radicals are damaging to cells using an oxidation process.

Current research suggests antioxidants can prevent or delay some serious medical conditions such as arterial disease or cancer.

Vitamin C found in fresh fruit and vegetables is an antioxidant. There are many others.

NOON

Lightening kills about 100 people in the USA each year. Most deaths occur outside eg on golf courses, athletic fields, in boats. Farmers are also at risk.

Bet you don’t know what’s in the very centre of the earth?

Molten iron, apparently.
