Get lost
often on city roads? Blame your brain
LONDON,
Jan 20: Do
you often get disoriented or lost while trying to
find a way through the city streets? Well simply
blame it on your brain.
Researchers in
Britain have found that two key parts of the
brain "talk" to each other and allow
people to remember routes as well as plan new
ones, but if either of these is not working, the
ability to find the way around gets impaired.
While the first
part called the hippocampus stores memories about
key locations and landmarks, the other brain
cells, known as grid cells, provide the internal
sense of space and distance, like a GPS system.
According to the
researchers, in those people who get lost easily,
navigation cells are less efficient at talking to
each other, so they get lost.
"People who
get lost easily don't make good use of their grid
cells. These provide us with information about
distance, movement and direction while linking to
memories about specific landmarks. For each
location a specific pattern of cells will send
signals to trigger a particular memory.
"For example
the entrance to Top Shop on your local high
street will have one pattern while another will
trigger a memory of St Pancras station. By
talking to each other in this way, the cells
allow the brain to produce a route it has to
follow," lead researcher Dr Hugo Spiers of
University College London was quoted by 'The
Sunday Telegraph' as saying.
According to them,
training the cells can help people navigate more
easily and it may explain how the city's cabbies
gain the "knowledge", the encyclopedic
memory of the city's streets required before they
can get a licence.
The findings have
been revealed as part of an exhibition at
London's Giomple Fils Gallery, funded by the
medical research charity Wellcome Trust. (PTI)_
India to
attend UAE meet on labour issues
DUBAI,
Jan 20: India
is among the 22 countries attending a three-day
meeting in UAE capital Abu Dhabi from January
20-22 which would make recommendations on
improving the market for temporary contractual
labour.
The meet which
would be attended by India's Minister for
Overseas Indian Affairs Vayalar Ravi would also
focus on protection and welfare of workers.
Labour ministers
and senior officials from 22 nations would
participate in the meeting titled 'The
Ministerial Consultations on Overseas Employment
and Contractual Labour for Countries of Origin in
Asia: The Abu Dhabi Dialogue'.
"The Abu
Dhabi Dialogue will discuss the entire cycle of
temporary contractual labour, beginning and
ending with national and human development,"
Labour minister Dr Ali Abdullah Al Ka'abi said.
Explaining the
importance of the meeting, Al Ka'abi said
"This year's meet is expected to strengthen
cooperation between countries of origin (of
labour) and destination.
The conference
will also "provide a forum for the 11 Asian
labour-source countries to share their views in
the field of labour mobility policies, review the
implementation of recommendations of the previous
Ministerial consultation in Bali, and identify
further steps for effective management of labour
mobility and temporary contractual labour for the
benefit of all concerned", he added.
The labour-sending
countries are India, Afghanistan, Bangladesh,
China, Indonesia, Nepal, Pakistan, Sri Lanka, the
Philippines, Thailand and Vietnam.
Participating
labour-receiving countries include GCC countries
and Yemen, Japan, Malaysia, Republic of Korea and
Singapore. (PTI)
US urges
OPEC to raise oil output
DUBAI,
Jan 20: The
United States has asked the Organisation of
Petroleum Exporting Countries (OPEC) to raise its
oil output to meet the growing energy demands.
"I think it
is possible for an increase in supply over a
period of time because there is adequate reserve
in the Kingdom," US Energy Secretary Samuel
Bodman said during a visit to Riyadh yesterday.
"The new
energy reality means the world must develop safe,
reliable, clean, affordable and diverse energy
supplies" he was quoted as saying by Arab
News.
The US official
stressed that the world needed a more diverse
group of energy suppliers and a more diverse
network of energy supply routes.
Quoting the recent
World Energy Outlook, Bodman, who met his
counterpart Ali Al-Naimi yesterday, said the
world's primary energy needs will grow by 55 per
cent by 2030.
"This alone
creates for the world a set of energy challenges
that require the active involvement of energy
producer and consumer countries. And no one
nation or a sector can meet them alone", he
added. (PTI)
Extinct
marsupial lion far superior to African lion
NEW
YORK, Jan 20: Pound for pound, Australia's extinct
marsupial lion would have made mince meat of
today's African lion had the two big cats ever
squared off in a fight to the death, if a study
is to be believed.
A team of
researchers has carried out the study and found
that the marsupial lion killed prey rapidly,
using its "bolt-cutter" type teeth to
scissor through hide and flesh, whereas African
lions use their bite force to suffocate prey,
using a "clamp and hold" technique.
"Our results
suggest that the marsupial lion employed a unique
killing technique. It used its massive carnassial
cheekteeth to effect major trauma and a rapid
kill.
"Unlike any
living mammalian carnivores, the marsupial's
carnassials were not only butchery tools but also
active components in the killing process,"
according to lead researcher Stephen Wroe of the
University of New South Wales in Australia.
Using a
sophisticated computer modelling method that
renders dynamic 3D models based on CT scans of
the marsupial's cranial mechanics and
musculoskeletal architecture, the team has found
that the creature's skull, jaw, and head and neck
muscles were well adapted to using the unique
technique for killing large prey.
"The
marsupial lion also had an extremely efficient
bite. In addition to very powerful jaw muscles
for its size, its muscle and skull architecture
were arranged in such a way as to take greater
advantage of leverage than in living cats,"
the 'ScienceDaily' quoted Wroe as saying. (PTI)
Immigrants
in UK opting for name change
LONDON,
Jan 20: Thousands
of newly arrived migrants in the UK, including
Indians, are adopting common British names to
avoid "discrimination" and
mispronunciation.
Indians bearing
the surname Shital prefer to be known as Sheet
while Arabic names such as Karim and Muhammad are
being changed to Kevin and Michael, according to
a report in 'The Sunday Times'.
The trend is part
of a boom in name changing, fuelled by websites
that allow people legally to rename themselves by
deed poll within a few hours, usually for about
30 pounds.
About 70,000
people are expected to change their name using
either the UK Deed Poll Service or the Name
Change Company this year, two of the most popular
services in Britain, th report said. In 2001, the
number of such people was fewer than 20,000.
The paper said
Chinese people have anglicised their names by
adding prefixes such as John, Jason and Sue. In
one instance, a refugee from Uzbekistan called
Avlar Jon Akherov became Adrian Barry Roberts. In
another case, a young Polish woman with an
18-letter surname opted for the brevity of one of
Britain's most common names - Hall.
The migrants
coming to the UK are adopting common British
names to avoid either discrimination or poor
pronunciation, the report said. (PTI)
