SLCERT initiates awareness campaigns:
Safe Internet use for schoolchildren
Educationists of all public and private sector educational
institutions and also parents should take measures to prevent
schoolchildren from accessing unsuitable websites while browsing the
Education Minister Bandula Gunawardana who was addressing a school
function in Veyangoda last week called upon teachers and parents to on
schoolchildren who access such websites at school computer labs, under
the pretext of browsing educational programmes.
Minister Gunawardana told the Junior Observer that many
schoolchildren in today's society have become victims of cyber crimes
due to the accessing of such unsuitable websites.
"It is the duty of teachers and parents to protect children of all
ages from watching pornography via the Internet, since it will not only
badly affect their personal lives, but also their on-going educational
Meanwhile, the Sri Lanka Computer Emergency Readiness Team (SLCERT)
has initiated a series of campaigns in schools to create an awareness
among teachers on `Safe Internet Useage' by children from their tender
The SLCERT believes that this message could also be spread to
students and their parents by conducting countrywide awareness
Longest lunar eclipse in a decade
An unusually long lunar eclipse lasting 100 minutes will be visible
over the Middle East, eastertern parts of Africa ,central Asia and
western Australia June 15 . This is the longest lunar eclipse since the
July 2000 eclipse. Sunlight which is usually reflected by the moon is
blocked by an eclipse creating a partial or total shadow.
after seven days spent trapped under rock
Jessie, a four -year-old Jack Russell terrier trapped for seven days
under 45 tons of rock has been freed. Her owner, Steve Porter, spent
more than $2,000 to rescue the pup.
Jessie the miracle Jack Russell that spent a week trapped
underground under 45 tonnes of rock at Mt Beckworth, Victoria,
Australia. She was stuck between enormous rocks and was only
able to wiggle her front paws and move her head. But the
devotion of her owner, Steve Porter, never wavered as he moved
the earth ‘literally’ to save his dog.
Jessie and Porter were rabbit hunting near their home in Australia
when Jessie darted after a feral cat and became trapped 11 feet
underground, beneath two boulders. Initially, Porter, along with his son
and two neighbours, tried to pry Jessie free. When that effort was
unsuccessful, they called the State
Emergency Service--Australia's EMS--to lend a hand.
As rescuers gradually sought to pry Jessie loose, they also sustained
her on bits of liver they sent down to her via a length of fencing wire.
"It's a miracle, really, when you see the size of the rock and the
location and how restricted we were," Porter told the Herald Sun.
After a week's efforts to pry Jessie loose, a rock-breaking truck
hired in from Melbourne finally sprang her from captivity."Dogs are
man's best friend," Porter told the Herald Sun. "We felt we owed it to
The easiest thing to say was the dog would die or we could say let's
give her a good hard go. And we did. We rallied together and we said 'We
can do this.' Where there's hope, there is life."
Once Jessie was freed she jumped into her owner's arms and gave him
"a big lick."
The vet reports Jessie is in good health despite her ordeal--though
presumably Porter won't be letting her off-leash to chase feral cats
Scientists crack the spiders' web
Decorative white silk crosses are an ingenious tactic used by
orb-weaving spiders to protect their webs from damage, a new study from
the University of Melbourne has revealed.
The team, led by Dr Andre Walter and Professor Mark Elgar from the
University of Melbourne's Department of Zoology, found that orb-weaving
spiders respond to severe damage to their webs by building bigger silk
crosses, but if the damage is mild they don't bother adding extra
decoration.Professor Mark Elgar said web damage is costly for spiders as
a lot of nutritional resources are required to rebuild a web.
"So they evolved this ingenious way to minimise unwanted damage," he
said."It's much like we mark glass windows with tape to prevent people
walking into them," he said.
The team collected a group of orb-weaving spiders and left them to
build their webs in the laboratory. Some of the completed webs were
severely damaged, others lightly damaged and the remainder left alone.
The response of the spiders was then observed.
"The fact that spiders increased their decorating activity in
response to severe damage but didn't increase their decorating following
light damage suggests that the conspicuous building of silk crosses
serves to make webs more visible to animals that might accidentally walk
or fly into them," Professor Elgar said.Adding silk decorations to
spiders' orb-webs was first reported over a century ago but why these
spiders decorate their webs has been the topic of controversial debate
"Our study helps unravel this mystery," Professor Elgar said.The
study was published in Behavioural Ecology and Sociobiology.
