Scientific Minds Want To Know
 |  | A supermassive black hole may have been observed in the process of being hurled from its parent galaxy at high speed. |
This weekend marks the 50th anniversary of the first demonstration of a ruby laser in the US Hughes Research Labs. | | A study details how two species from different taxonomic kingdoms - animal and plant - compete for the same food. |
For reasons as yet unknown, a dark band on the giant planet's southern hemisphere has recently vanished.Researchers have discovered the fossilized remains of a primate that may have lived in Africa as long as 37 million years ago, but defies classification as to what species it belonged.
First mathematical model of cow behavior
Why does a herd of cows stand or lay down at the same time? Researchers at Clarkson University in New York have worked out a mathematical model to explain the workings behind collective behavior in bovines.
"OK, cool. But, seriously," you may ask, "is that really important?" Actually, yeah.
Happy cows tend to copy each other. And happy cows are also more productive by various measures such as the amount of milk they produce. Some researchers have even proposed that synchrony be used as a measure of the quality of bovine life.
That will ring a bell with many farmers who keep their cattle indoors during winter. They have long recognised that when cattle are so crowded that there is not enough room for them all to lie down at the same time, productivity drops dramatically. In fact, in some parts of the world there are rules about how much space cattle must have to lie down in. The new model could help determine the level of coupling that maintains production.
The atmosphere's current hue probably differed long ago, a new study suggests.

The biggest and brightest star in our galaxy and an enormous hole in space confound scientists.
Also: 
Philosophers and scientists have argued about the origins of life from inorganic matter ever since Empedocles (430 B.C.) argued that every thing in the universe is made up of a combination of four eternal ‘elements’ or ‘roots of all’: earth, water, air, and fire, and that all change is explained by the arrangement and rearrangement of these four elements. Now, scientists have discovered that simple peptides can organize into bi-layer membranes. The finding suggests a “missing link” between the pre-biotic Earth’s chemical inventory and the organizational scaffolding essential to life.
