When a newt loses a limb, the limb
regrows!
Scientists at the
Max Planck Institute for Heart and Lung Research have started to
decode the cellular mechanisms in this ability to regenerate and
have discovered the remarkable plasticity of newt heart cells.
As mammals, and
therefore also humans, do not have this ability, the findings
could contribute to new cell therapies for patients with damaged
organs.
The red-spotted newt,
Notophthalmus viridescens, is a favourite animal of the
researchers. This amphibian comes from the wetlands of
North America.

Hibernating newts block drains!
Attempts by staff at Cuerden
Valley Park to improve the drainage of the 650-acre site have
been thwarted - by Newts.
The recent wet weather has caused several puddles at the popular
attraction between Chorley and Bamber Bridge.
However, when the park's rangers were carrying out maintenance
work on drainage channels that prevent standing water forming,
they made an unlikely discovery.
A number of newts had travelled from their natural habitat of a
nearby pond and were hiding in the channels for the winter.
Anyone touching the creatures
without the required licence faces a fine of £1,000 per newt
because they're a protected species.
Development officer Steve Williams said: "Amphibians hibernate
in dark, damp places which is why they were attracted to the
drainage channels.
"You need a special licence to handle them. We have got
one ranger, Richard Tanner with the licence.
"If there were no newts we would normally lift the channels out
and scoop out the debris to improve the drainage. But
instead we have got to let nature take its course.
"We ask out visitors to be understanding."
The drainage system is securely installed which means the newts
are not in danger and the visitors can carry on walking along
the paths as normal.
"The channels are screwed down,
so members of the public do not need to tip-toe around the
newts," said Mr Williams.
"We would, however, like to
encourage visitors not to provoke the newts in any way.
"We welcome feedback from our visitors but unfortunately, when
it comes to blocked drains, our hands might be tied by newts!"
Cuerden Park run a series of
unique events throughout the year that give the public a chance
for a detailed look at the different species and nature included
in the park. |

The knotty problem of what infects the
newts.
It could be blood-sucking leeches.
A fungus-like parasite has been
found in several kinds of North American amphibians, including
bullfrogs and the red-spotted newt. But scientists
couldn't explain how they were getting infected. Now, some
Pennsylvania Stat University biologists think they have the
answer - Blood-sucking leeches. Although it is not proven
directly, but the leeches appear to be carrying the parasite
from newt to newt with their bites. Signs of infection
were on the body parts most likely to be bitten by leeches, such
as the head and throat. The infection does not kill the newts,
but it does appear to stop them from breeding.

Clarion call to save amphibians
Hundreds of amphibian species will become extinct unless a
global action plan is put into practice very soon,
conservationists warn.
Campaigners are forming an Amphibian Survival
Alliance, to raise $400m and carry through a rescue strategy.
More than a third of all amphibian species are said to be in
peril.
In a policy statement issued in the journal Science, researchers
blame a number of factors including habitat loss, climate change
and disease.
"We have a huge crisis but I'm confident we
can produce some real results," said Simon Stuart, from
Conservation International (CI).
"The questions is: how many species will we
lose? Are we going to lose hundreds before we can stabilise the
situation or are we going to lose just tens," he told the BBC
News website.
"Time is absolutely crucial, and to beat time
we need human recourses and expertise, and finance."
