Sea Slug Latrunculin A. Toxin to Treat Cancer

Chemistry: sea slug toxin will kill cancer cells.
Sea slugs can be beautiful with their brightly colored coats. However, they carry the most toxic substances known. They display "you can't miss us" patterns because enemies try to avoid them.

They eat meat. The closest thing to a vegetable that they consume are sponges. t is the toxin stored in their bodies. They get this from food. Shrimps die immediately when they are attacked by sea slugs. Apparently, a sea slug will die if Latrunculin A. gets into its bloodstream.

Tests show that the main sea slug toxin will kill cancer cells. It could potentially also be used to treat neurodegenerative disease. The problem is of course finding a transport medium and getting it to market.

El Niño Threatens but La Niña Persists in Australia

While a new very strong El Niño is on the way, fears of continuing La Niña are real as well. Although Australia is known as a drought country, severe floods are damaging. This is because the continent is flat with a few mountains in the east of the country.
If the El Niño does not arrive flooding will continue. Furthermore, the drought in the US will cause further damage to their economy. The odd thing at the moment is that Australia has drought inland with flooding along the coast. This isn't s normal state of affairs. It could be due to global warning.

We have had a very long intermediate period where La Niña persists and El Niño threatens. Research shows that La Niña will return every 13 years instead of 23 years. It seems to Australians that La Niña has been here for ever with the long intermediate period persisting. There are extreme El Niño and La Niña though. And it is these that do the most damage economically and socially.

Oil Found Off Australia's North West Coast

There has always been a belief that Australia's future lies in finding a mineral that is plentiful in the north west of the country. Till now this has not been achieved. Everyone knows that Western Australia is full of iron ore so this is not what they are looking for.

Drilling for many years has just made holes in the ground. Companies have gone over ground already explored before. This is how the latest find was made. There is oil there and in vast quantities. Apache Corp. has made the announcement that was greeted with surprise by some people.

Apache was searching for gas when it made the discovery. Considering Australia's oil production has fallen to its lowest level for forty years this can only be good news.

Income to Western Australia from iron ore has declined due to a fall in Chinese demand. The price for iron ore is down by a third since January. Australia is producing far more ore than it can sell. Coal is not doing well either.

The oil found by Apache is of very high quality so a high price is expected for it when it eventually comes on line. Unfortunately, it could be some time before this happens. Normally developing a new oil field takes decades.

Climate Change - Buildings Down and the Surf

Australia has always been a harsh place to live. Despite the luxury living on the coast with all the latest modern services, inland there is a desert. Many people who are born in the harsh center remain there all their lives. A fewer number choose to live there moving from coastal cities. Let's face it many prefer the heat over the cold and they have personal reasons for choosing to do this.

We do yet know what lies ahead for us in this vast continent. Climate change is happening at this very moment most definitely. El Niño and La Niña are the major factors influencing the weather on the east coast. Scientists forecast more extremes from these usually opposite climate impacting factors. The intermediate stage between these cycles has lasted for several years now. Weather is very unpredictable ranging from drought inland to too much rain on the coast. It seems we experience one or the other extreme with changeable in between.

The level of the ocean is rising. Coastal buildings will be inundated and lost forever. Oddly, this is bad news for surfers. As the sea rises the surface becomes smoother. This means smaller waves on the beaches. The era of Australia being a surfing nation could come to an end. Storms along the coast will decrease further exacerbating the problem. With more water volume, temperature differences in the ocean even out leading to calmer weather. The few storms that will occur will be very large indeed. High-rise buildings on the Gold Coast in Queensland will fall into the sea. We will lose our tourist mecca.

New Dolphin Species Found in Australia

It is amazing that a species of dolphin has been living along the coast of Australia and scientists did not know it - until now. The Burrunan dolphin is the third new species to be identified since the 1800s. Named Tursiops australis, the new mammal is represented by two small groups living among bottle-nosed and common dolphins living off the Victorian coast.

They are quite distinct from other dolphins having different body shape, skulls and DNA sequence. The discovery came as quite a shock and shows that new species of other animals could be living unidentified in regions already extensively examined.

Man may be going into space but much of our planet still remains unexplored. New species still need to be classified in South America. The behavior of some creatures is not yet fully understood. For example, giant catfish in Asia are suspected of taking people swimming across rivers.

New Jellyfish in Coffs Harbour

It seems humans know just about everything. This is a myth really. A new species of jellyfish has be seen in Coffs Harbour, NSW. It seems the marine creature has been there for a long time.

The mystery "object" is a box jellyfish that appears to be totally harmless. It is unlike the Irujandji and is smaller than the dangerous Chironex flecker box jellyfish. Fishermen have been seeing the new jellyfish for sometime but authorities took no notice. A game crew took photos of the animal last week.

Finally "professionals" acted and arrangements are being made to catch some specimens. Fish of all kinds are moving south as the temperature of the ocean increases due to climate change. It is believed the visiting jellyfish come from more northern climes. Usually jellyfish do not move south because they can be harmed by rougher seas. They prefer the warm, calmer tropics.
