GLP-1 from Platypus Venom Gives Hope for New Diabetes Treatment

Researchers have discovered that the same hormone produced in the platypus gut and stinging spurs has potential for type a 2 diabetes treatment to regulate blood glucose levels. Hormone helps diabetics.

There Is Soil on Mars

NASA scientists are now saying that "soil" on Mars could support vegetable life. Without an atmosphere, though, it seems no life is possible. Scientists are specific enough to say that asparagus and turnips will grow in Mars' soil but strawberries will not. Are they joking? Or are they for real?

The Phoenix Mars Lander found soil that is very much like that in many Earth backyards. Scientists are shocked that they have found soil. It is alkaline - thus, the claim that it is not good for strawberries. Apparently, the soil is rich in trace minerals.

My, how scientists can be wrong. It was thought that Mars "soil" would be salty - with no atmosphere and the sun would bleach it. But they were wrong. At least we know that there is soil and water in the form of ice just beneath the surface. There is evidence that in the past water flowed on the surface because erosion is evident. Rivers, lakes and oceans existed there once. Water reservoirs such as these indicate that the planet did once have an atmosphere.

If life did survive for a time on Mars future exploration will surely find it.

Australian Researcher Discovers a New Chlorophyll

A new form of chlorophyll has been identified in Shark Bay stromatolites by Min Chen of the University of Sydney. She has been awarded the Science Minister's Prize for Life Scientist of the Year.

Chlorophyll had previously been found in four forms. It is a plant pigment that makes sugar giving energy to plants. The new type called chlorophyll f operates in the upper red end of the visible spectrum. Future uses include solar cells and new kinds of food crops.

The new type of chlorophyll was found by studying cyanobacteria within stromatolites. It was an accidental discovery. The intention was to understand more about chlorophyll d. Both types of chlorophyll are similar, but have different bonding structures.
