Chlorophyll


Chlorophyll

Chlorophyll is a green pigment that gives most plants their color and enables them to carry out photosynthesis, the process through which plants get energy from light. Chlorophyll absorbs light in the red and blue-violet portions of the visible spectrum; the green portion is not absorbed and, reflected, gives chlorophyll its characteristic green color. Only one animal has been found to use the chlorophyll it has eaten to perform photosynthesis for itself. What is it? More… Discuss

ST. LOUIS – Authorities have arrested at least two people at a protest over the Ferguson grand jury decision in which several demonstrators stormed City Hall in St. Louis.

An undetermined number of protesters made it into the building Wednesday while shouting “Shame, shame.”The protest march included several hundred people and began with a mock trial of Ferguson Officer Darren Wilson, who shot and killed 18-year-old Michael Brown. It was held on the steps of the Old Courthouse, the site of the Dred Scott trial.More than 100 additional police officers were called to the building and it was locked down.

A total of 58 people were arrested at area protests overnight, including 45 in Ferguson.

Hopping Relatively Recent Development in Kangaroos


Hopping Relatively Recent Development in Kangaroos

Kangaroos are known for their characteristic hop, but they didn’t always get around like this. Analysis of the fossilized bones of extinct kangaroos called sthenurines finds that they were not anatomically cut out for hopping and likely got around instead by walking in much the same manner that humans do. Sthenurines lived in Australia from about 13 million years ago to about 30,000 years ago, going extinct around the same time that humans arrived on the continent, quite possibly as a result of human activities.
