Ocean Mysteries: 'Immortal' jellyfish from Caribbean capable of reverting to younger self spreading all over world
Marine biologists say the jellyfish numbers are rocketing because they need not die. Dr Maria Miglietta of the Smithsonian Tropical Marine Institute said: "We are looking at a worldwide silent invasion."
The jellyfish are originally from the Caribbean but have spread all over the world. Found in warm tropical waters Turritopsis is believed to be spreading across the world as ships’ ballast water is discharged in ports.
Turritopsis Nutricula is technically known as a hydrozoan and is the only known animal that is capable of reverting completely to its younger self. It does this through the cell development process of transdiff- erentiation. Scientists believe the cycle can repeat indefinitely, rendering it potentially immortal.
Though solitary, they are predatory creatures and evolve asexually from a polyp stage. While most members of the jellyfish family usually die after propagating, the Turritopsis nutricula has developed the unique ability to return to a polyp state. read more »

There is pleasure in the pathless woods;
There is rapture on the lonely shore;
There is society, where none intrudes,
By the deep sea, and music in its roar:
I love not man the less, but Nature more.
Nature perturbed: icy darkness in N Amer; 1st-time-in-100-yrs heatwave cooks egg on court at Australia Open in 60C
Above: players and fans at the Australian Open tennis tournament did their best to keep cool.
An egg cooked after ten minutes on an outside court where air temperatures reached 60C. The official temperature in the shade at 4.53 pm was 45.4C, the hottest since 1908.
A heatwave scorching southern Australia, causing transport chaos by buckling rail lines and leaving more than 140,000 homes without power, is a sign of climate change, the government said.
"It is the worst heatwave most will have lived through," senior forecaster Terry Ryan said in a front-page story headlined "Heat Wave Hell". But this lot looked like they were enjoying it.
Freezing snow threatens to shut down UK. Is it caused by 30% reduction in warm ocean currents..discovered in 2005?
Arctic blizzards are set to cause a national shutdown on Monday as forecasters warn of the most widespread snowfall for almost 20 years.
The Met Office is warning of an "extreme weather event" across large swathes of England, Scotland and Wales with up to 10in of snow expected even in the usually warmer south and as much as 1ft on higher ground. With freezing temperatures expected to endure for at least a week, there were predictions that resulting disruption and an expected spike in absenteeism could cost the British economy as much as £600 million a day, as the public transport system grinds to a halt and schools and offices are forced to close.
As hundreds of thousands are left without power, forecasters fear floods will follow worst weather for a decade
With 680,000 people still without electricity in France and 50,000 in Spain... read more »
"SOS Amazon": 1st action of Amazon tribes, sending message "Wake Up, World!" at 2009 World Social Forum in Brazil
BELÉM, Brazil, Jan 27 (IPS) - A human banner made up of more than 1,000 people, seen and photographed from the air, sent the message "SOS Amazon" to the world, in the first action taken by indigenous people hours before the opening in northern Brazil on Tuesday of the 2009 World Social Forum (WSF).
The mass message reflects "our concern about global warming, whose impact we will be the first to feel, although we, the peoples of the Amazon, have protected and cared for the forests," Francisco Avelino Batista, an Apurinán Indian from the Purus river valley in the Brazilian Amazon, told IPS.
One touch of nature makes the whole world kin.
