5 Unusual Facts About Stars

Orion constellation

1. Most of the stars you view from the earth at night are actually binary stars. That is, two stars circle each other creating an imagined point of gravitation, or a smaller star circles around the “main star”. Sometimes these main stars draw material from the smaller one, as they come closer to each other. There is a mass limit that a planet can hold without fusing nuclear reaction. If Jupiter was larger it might have fused as a brown dwarf, a kind of semi-star, many moons ago. It is actually more common in other solar systems, evidenced by their relative lack of planets. This is because most of the material which is locked in the gravitational field of the main star gathers up in one place, which in the end lights up as a star and forms a binary system. There can also be more than two stars in one system, yet binary systems are more common.

Release of Exotic Pets Harms Florida Everglades

//

The Florida Everglades National Park was the first park established in the United States not for its scenic value but to benefit life. The Everglades protect fresh water, boost tourism and provide habitat for many wildlife animals including commercial and sport fish as well as game species for hunting.

Today, the Everglades are only 20% of their original size, but they are an important nursery for many wildlife species. Dozens of endangered and threatened species live in the Everglades, including the Florida panther, the American crocodile and the wood stork.

While development has done irreparable damage to the Everglades – Miami and Ft. Lauderdale are both located in historic Everglades area – one of the biggest threats to the Everglades is the release of exotic pets.

How the Mind Controls the Way Your Body Responds to Allergies

Allergies are a source of misery for millions of people worldwide, most of whom would probably be very surprised to hear their mind is at least partly responsible. But this was the finding of a group of neurosugeons from Neuroscience Research Australia and the University of South Australia.

In two separate tests, Prof. Lorimer Moseley and his team administered histamine, the substance our body makes during an allergic reaction, to the arms of healthy volunteers. The twist was that half the volunteers were convinced, through an illusion, that one of their real arms was actually just a rubber replacement. In reality, both their real arms were given histamine.

Giant Western Gray Whale Floats Down the River Thames

The people of London were greeted by an uncommon spectacle this week as an enormous western gray whale floated down the River Thames. Bearing in mind the fact that such giants of the deep are usually only found in the Pacific Ocean, bystanders could be forgiven for wondering what on Earth the reason was behind this strange cetacean sighting.

The truth is that the World Wildlife Fund (WWF) were responsible, having brought in what was in fact an 11 meter-long (36ft) life-size replica to focus attention on a threat to the species – which is already on the brink of extinction. There are thought to be as few as 130 western gray whales left on the planet, with only 26 breeding females, but today this population faces a new danger that could push them out of existence.
