Weird Fanged Fish Found in Australia

Researchers on an Australian exploration ship got more than they bargained for when they searched an area near Sydney in New South Wales. They were examining lobster larvae but discovered something really snappy. On the sea floor near ancient volcanoes they found an odd fanged fish.
Snaggletooth dragonfish genus Astronesthes
The tiny fish a bit larger than your thumbnail is as black as coal. While the fish has probably already been named in the snaggletooth dragonfish genus (Astronesthes) these fish have rarely been seen. There are ten fish species of this type located in the region. Further analysis will be need to find out if it is a new species.

The larvae of common fish such as flatfish, gurnard, kingie and Dolphin fish were also seen there. This surprised scientists who had previously thought that they were washed into the path of predators by the current. It seems the dragon fish came up from the depths to join them.

New Hope for the Obese

A hormone has been identified that makes a person feel full. This "anti-eating" hormone can be taken orally. It easily gets into the bloodstream. The discovery has been made by a combined team from Murdock University Australia, and Syracuse University in the US. Obese people have less PYY hormone. The treatment is so effective that even naturally thin subjects lost weight.

Normally, PYY is absorbed in the stomach. Researches have found a way of attaching the hormone to vitamin B12 that carries PYY through the stomach into the bloodstream. Some is lost but a significant amount gets through.

The medication will be made available in tablet form and chewing gum. Patients will have to stay on the treatment for a target period: the PYY dose takes up to four hours to get into the system and begin to have an effect. This would mean that patients will have to take a tablet directly after a meal, lunch for example, for it to suppress appetite at tea or dinner.
