Good
health: India eating better
|
| |
|
Indians
are on the high road to health and
wellness. Their eating habits have
turned distinctly healthier - more
green vegetables, less red meat; more
fruits and milk, less smoking; more
pulses, chicken and eggs, less saturated
fat like vanaspati and coconut oil.
These are the findings of a study
by National Sample Survey Organisation
which has captured the country's stay-fit
spirit - a spirit already sweeping
developed countries. While the study
has not captured whether Indians are
exercising more or not, it has found
they are spending more on healthcare
than before. There's been a switch
to cooking mediums like sunflower,
corn and soya oil, pitched as healthier
than traditional options, like mustard
and coconut oil and vanaspati. Smoking
too has dropped 30% in urban areas
in the 11-year period since 1993-94.
The proportion of households with
at least one bidi smoker has dropped
26% (rural India) and 35% (urban).
The nationwide Consumer Expenditure
Survey was carried out on a sample
of 79,298 rural and 45,346 urban households
in 2004-2005. It tracked changes in
consumer behaviour in the preceding
decade and found people in rural areas
were increasingly giving up on coarser
grains like jowar while turning to
more nutritious, protein-rich items
like pulses. This could explain the
current mismatch between demand and
supply of pulses and its high prices.
It could also mean that high demand
for pulses is here to stay. While
consumption of milk has gone up by
a mere five percentage points in both
rural and urban India between 1993-94
and 2004-05, people have taken to
eating eggs with a vengeance - egg
consumption going up by nearly 60%
in rural India. In keeping with latest
health trends, people are giving up
red meat, while the consumption of
chicken has gone up by three times
in urban areas and by two-and-a-half
times in rural areas. Consumption
of fruits and vegetables is also up,
with a five to 15 percentage point
increase in intake of various vegetables.
This indicates rising demand for veggies.
Perhaps their prices won't come down
to levels we knew a few years ago.

Myanmar
Armed Forces To Step Up Operations
Against North East Militants
|
| |
|
Myanmar
will soon launch a military offensive
to evict Indian separatists from its
soil following New Delhi's request
to crack down on rebel bases in that
country, Indian officials said Friday.
'The Myanmar army has promised to
step up the fight against militants
from our northeast states based in
their country,' an Indian Army commander
told IANS on condition of anonymity.
Myanmar's decision to crack down on
Indian rebel bases was made by Brigadier
General Tin Maung Ohn who was leading
an 18-member Myanmarese army delegation
to India. The Myanmar team, during
the last five days, held extensive
meetings with India's army and paramilitary
commanders in the northeastern states
of Nagaland and Assam. 'This is the
first breakthrough, with Myanmar deciding
to take proactive action against those
(Indian militants) that already exist
in their country,' Paramjit Singh,
director general of the Assam Rifles,
a paramilitary force engaged in anti-insurgency
operations in the northeast, told
reporters. New Delhi has mounted pressure
on Yangon to launch a military offensive
against Indian militant groups - mainly
the outlawed United Liberation Front
of Asom (ULFA) and the United National
Liberation Front (UNLF). The ULFA,
a rebel group fighting for an independent
homeland in Assam, is on the run since
the Indian Army launched a crackdown
in January after the group killed
80 people. 'The ULFA militants have
sneaked into bases in Myanmar. If
the military junta there launches
an operation, it would be easier for
us to deal with militancy here,' the
commander said. At least five major
militant groups from India's northeast,
where numerous tribal and ethnic groups
are fighting for greater autonomy
or independence, have training camps
in the dense jungles of Sagaing in
northern Myanmar. 'There are at least
20,000 guerrilla fighters in Myanmar
belonging to various groups of the
northeast,' said Kughalo Mulatonu,
a rebel leader of the S.S. Khaplang
faction of the National Socialist
Council of Nagaland (NSCN-K). The
NSCN-K, a rebel group fighting for
an independent tribal homeland in
Nagaland, operates out of Myanmar
with the outfit's general headquarters
located in Sagaing. Myanmar had earlier
pledged that the junta would not let
Indian rebels operate from its soil.
The country last year launched a military
operation against the NSCN-K, killing
at least a dozen rebels and overrunning
several of their bases. India and
Myanmar share a 1,640-km long unfenced
border, allowing militants from the
northeast to use the adjoining country
as a springboard to carry out hit-and-run
guerrilla strikes on Indian soldiers.
The rebels say they are seeking to
protect their ethnic identities and
allege that the central government
has exploited the resources in the
region rich with mineral, tea, timber
and oil. Over 50,000 people have lost
their lives to insurgency in the northeast
since India's independence in 1947.

Sleep
protects memories: study
|
| |
|
Sleep,
a period of rest common to all living
beings, protects memories, says a
study that provides important insights
into how slumber influences memories.
Researchers studied 48 healthy adults
aged 18-30, dividing them into four
groups. All of them were told to remember
certain words. The students who slept
at home before the tests performed
best, correctly identifying three-quarters
of the word pairs. The students who
took the test before going home for
the evening correctly identified one-third
of the word pairs, the online edition
of health magazine WebMD reported.
"This is the first study to show that
sleep protects memories from interference,"
said researcher Jeffrey Ellenbogen,
a neurologist and fellow in sleep
research at Harvard Medical School.
"These results provide important insights
into how the sleeping brain interacts
with memories. It appears to strengthen
them," he said. "Perhaps, then, sleep
disorders might worsen memory problems
seen in dementia." The study will
be presented May 2 in Boston at the
American Academy of Neurology's 59th
annual meeting.

Vanishing
honeybees mystify scientists
|
| |
|
Go
to work, come home. Go to work, come
home. Go to work -- and vanish without
a trace. Billions of bees have done
just that, leaving the crop fields
they are supposed to pollinate, and
scientists are mystified about why.
The phenomenon was first noticed late
last year in the United States, where
honeybees are used to pollinate $15
billion worth of fruits, nuts and
other crops annually. Disappearing
bees also have been reported in Europe
and Brazil. Commercial beekeepers
would set their bees near a crop field
as usual and come back in two or three
weeks to find the hives bereft of
foraging worker bees, with only the
queen and the immature insects remaining.
Whatever worker bees survived were
often too weak to perform their tasks.
If the bees were dying of pesticide
poisoning or freezing, their bodies
would be expected to lie around the
hive. And if they were absconding
because of some threat -- which they
have been known to do -- they wouldn't
leave without the queen. Since about
one-third of the U.S. diet depends
on pollination and most of that is
performed by honeybees, this constitutes
a serious problem, according to Jeff
Pettis of the US Agricultural Research
Service. "They're the heavy lifters
of agriculture," Pettis said of honeybees.
"And the reason they are is they're
so mobile and we can rear them in
large numbers and move them to a crop
when it's blooming." Honeybees are
used to pollinate some of the tastiest
parts of the American diet, Pettis
said, including cherries, blueberries,
apples, almonds, asparagus and macadamia
nuts. "It's not the staples," he said.
"If you can imagine eating a bowl
of oatmeal every day with no fruit
on it, that's what it would be like"
without honeybee pollination. Pettis
and other experts are gathering outside
Washington for a two-day workshop
starting on Monday to pool their knowledge
and come up with a plan of action
to combat what they call colony collapse
disorder. "What we're describing as
colony collapse disorder is the rapid
loss of adult worker bees from the
colony over a very short period of
time, at a time in the season when
we wouldn't expect a rapid die-off
of workers: late fall and early spring,"
Pettis said.

Science
seal on Muslim history
|
| |
|
by
G.S. Mudur
Scientists
have confirmed what historians have
known. Genetic studies have suggested
that Muslims in northern India are
mostly descendants of local people
who embraced Islam rather than repositories
of foreign DNA deposited by waves
of invaders. The studies by scientists
in India, Spain and the US indicate
that while the Shias and the Sunnis
in Uttar Pradesh are mostly descendants
of converts, the former have some
elements of paternal foreign ancestry.
But overall, the Shias and the Sunnis
in Uttar Pradesh display higher genetic
affinity to northern Indian caste
populations than to western or central
Asian populations. The findings, based
on the analysis of genetic material
from 60 Sunni and 59 Shia volunteers,
will appear in the American Journal
of Physical Anthropology. The researchers
say their studies are the first to
test two ideas on the ancestry of
northern Indian Muslims - they may
be descendants of local people who
converted to Islam, or they may represent
bloodlines of Muslims who arrived
in several waves between the 8th and
14th centuries. "Our results point
to conversions in both groups, but
greater foreign ancestry in the Shias,"
said Suraksha Agrawal, a team member
and head of medical genetics at the
Sanjay Gandhi Postgraduate Institute
of Medical Sciences, Lucknow. Agrawal
has tried to piece together maternal
and paternal lineage of Muslims by
analysing genetic material called
mitochondrial DNA (mtDNA), which is
acquired only from mothers, and Y
chromosome, which is passed down only
by fathers. "In the mtDNA, we do not
see discrete signals from outside
India," Rene J. Herrera, a biologist
at Florida International University
in the US and one of the collaborators,
said. "Thus, both are, for the most
part, descendants from local caste
groups," he told The Telegraph. However,
the Shias do show some signatures
of foreign DNA from southwest Asia
and North Africa in the Y chromosome,
Herrera said. "Until now, there has
been no genetic study to explore the
historical extrapolations of Muslim
ancestry in India," Herrera added.
"History can get contaminated over
time. But DNA does not lie."

Sleep
enforces the temporal sequence in
memory
|
| |
|
A
research group headed by Jan Born
at the University of Lübeck has now
provided evidence that sleep not only
strengthens the content of a memory
but also the particular order in which
they were experienced, probably by
a replay of the experiences in "forward"
direction. We have usually quite strong
memories of past events like an exciting
holiday or a jolly birthday party.
However it is not clear how the brain
keeps track of the temporal sequence
in such memories: did Paul spill a
glass of wine before or after Mary
left the party? Previous findings
from a research group headed by Jan
Born at the University of Lübeck have
confirmed the widely held view that
long-term memories are formed particularly
during sleep, and that this process
relies on the brain replaying recently
encoded experiences during the night.
The same research group now provides
evidence that sleep not only strengthens
the content of a memory but also the
particular order in which they were
experienced, probably by a replay
of the experiences in "forward" direction.
Students were asked to learn triplets
of words presented one after the other.
Afterwards they slept, whereas in
a control condition no sleep was allowed.
Later, recall was tested by presenting
one word and asking which one came
before and which one came after during
learning. Sleep was found to enhance
word recall, but only when the students
were asked to reproduce the learned
words in forward direction. This finding
shows that sleep associated consolidation
of memories enforces the temporal
structure of the memorized episode
that otherwise might be blurred to
a timeless puzzle of experiences.

Oldest
tree had fronds, not leaves
|
| |
|
The
branches of Earth`s oldest tree probably
waved in the breeze like a modern
palm, scientists said on Wednesday,
based on two intact tree fossils that
help explain the evolution of forests
and their influence on climate. The
385-million-year-old fossils, which
scientists believe are evidence of
Earth`s earliest forest trees, put
to rest speculation about fossilized
tree stumps discovered more than a
century ago in Gilboa, New York. Scientists
believe these early forests absorbed
carbon dioxide, cooling the Earth`s
surface. The forests were flourishing
at an important juncture in the history
of life of Earth, coming shortly before
the appearance of the first vertebrates
-- four-legged amphibians -- that
could live on dry land.
"We`ve
solved this long-standing puzzle,"
said Linda VanAller Hernick, a paleontologist
at the New York State Museum, who
wrote about her discovery in the journal
Nature. The stumps in Gilboa were
unearthed in 1870 when workers were
blasting a quarry. Until now, scientists
had never seen the tops of those trees.
Hernick and museum colleague Frank
Mannolini discovered an intact crown
and part of a tree trunk in 2004 and
a year later found a 28-foot (8.5-metre)
trunk portion of the same species.
Pieced together, they represent Wattieza,
a tree that looked like modern-day
palm with a crown of fronds that grew
up to 30 feet high and reproduced
through spores. "Previously, paleobotanists
thought that a tree called Archaeopteris
was the oldest tree. Now we know there
were tree-like plants in abundance
much earlier," Hernick said in a telephone
interview. The fern-like trees are
about 23 million years older than
Archaeopteris, which Hernick said
resembled a modern tree, with conventional
branches. Instead of leaves, the Wattieza
had frond-like branches with branchlets
that resembled a bottlebrush, said
William Stein, a paleobiologist at
Binghamton University in Binghamton,
New York, and co-author of the study.
The tree branches fell to the forest
floor, providing a potential food
source and shelter for living creatures,
the researchers said. "This is a spectacular
find which has allowed us to recreate
these early forest ecosystems," said
British researcher Christopher Berry
of Cardiff University, who worked
on the study. Berry said the branches
would have decayed, providing a new
food chain for the bugs living below.
"The rise of the forests removed a
lot of carbon dioxide from the atmosphere.
This caused temperatures to drop and
the planet became very similar to
its present day condition," he said
in a statement. For Hernick, who was
inspired to become a paleontologist
after viewing the Gilboa stumps as
a child, the discovery offers a fair
bit of personal satisfaction. "It`s
kind of nice to bring this story to
a close," she said.

"Instant
face lift" chemical DMAE damages skin
cells
|
| |
|
A
chemical used in cosmetic products
promising an "instant face lift" makes
wrinkles disappear by damaging skin
cells, Canadian researchers report.
"From our point of view the cells
are altered. They stop dividing, they
stop secreting, and after...24 hours
a certain proportion of them die,"
Dr. Francois Marceau of the Centre
Hospitalier Universitaire de Quebec
told news agencies. Marceau, a cell
biologist, said he is reluctant to
recommend that these products not
be used. However, the findings make
it clear that more research is needed
on how these and similar products
work. "I don`t want to scare people,"
he added. "The risk is not probably
very big, but in my opinion it hasn`t
been measured accurately." Marceau
and his team tested 2-dimethylaminoethanol
(DMAE) in cultured rabbit and human
skin cells. As the researchers predicted,
applying the product caused a massive
and rapid swelling of the cells as
they filled with DMAE and water, leading
to a thickening of the epidermal layer.
They also found that DMAE was toxic
to the skin cells, halting cell division,
inhibiting secretion, and killing
some cells after 24 hours of exposure.
This "facelift in a jar" chemical
is certainly safer than a real facelift,
or Botox injections, Marceau noted.
Nevertheless, the fact that DMAE and
other "cosmeceuticals," such as triethanolamine,
aren`t considered drugs means they
are sold with very minimal information
about how they work and their toxicity.
"We know far less for these chemicals
than for any new drug that has been
marketed in the last 30 years," Marceau
said. "What I`d like to see is more
science in this field." These chemicals
should be treated as drugs, and many
studies, such as of mode of action
and toxicology, should be completed
before it is marketed.

Eat
your greens to cut cancer risk
|
| |
|
New
research is strengthening evidence
that following mom's admonition to
eat your vegetables may be some of
the best health advice around. A large
study of 500,000 American retirees
has found that just one extra serving
of fruit or vegetables a day may reduce
the risk of developing head and neck
cancer. Numerous studies have demonstrated
that diet plays a role in cancer.
Cancer experts now believe that up
to two-thirds of all cancers come
from lifestyle factors such as smoking,
diet and lack of exercise. "It may
not sound like news that vegetables
protect from cancer, but there is
actually some controversy in the literature.
It is important that we do these large
studies," said Alan Kristal, associate
head of the cancer prevention program
at Fred Hutchinson Cancer Research
Center in Seattle. Researchers at
the National Cancer Institute queried
men and women aged 50 and older about
their diets, then followed participants
for five years to record all diagnoses
of head and neck cancer, which is
the sixth-leading cause of cancer-related
death worldwide. Tobacco and alcohol
use increase the risk of head and
neck cancers, which affect the mouth,
nose, sinuses and throat. The study
found eating six servings of fruit
and vegetables per day per 1,000 calories
cut the risk of head and neck cancer
by 29% compared to eating one and
a half servings. The typical adult
consumes around 2,000 calories a day.
"Increasing consumption by just one
serving of fruit or vegetables per
1,000 calories per day was associated
with a 6% reduction in head and neck
cancer risk, said Neal Freedman, cancer
prevention fellow at the NCI. A second
study of food consumption in more
than 183,000 residents of California
and Hawaii found that a diet high
in flavonols might help reduce pancreatic
cancer risk, especially in smokers.
Flavonols are common in plant-based
foods but are found in highest concentrations
in onions, apples, berries, kale and
broccoli.

NASA
paid USD 26.6 mn to families of Columbia
astronauts
|
| |
|
NASA
paid USD 26.6 mn to the families of
seven astronauts who died aboard space
shuttle Columbia, a settlement that
has been kept secret for more than
two and a half years, a report said.
Indian-American astronaut Kalpana
Chawla was among those killed when
the shuttle broke up as it re-entered
the earth's atmosphere on February
1, 2003. An investigation later discovered
that chunks of insulation shed from
the tank during take off damaged Columbia's
left wing leading to the disaster.
Reporting this, Orlando Sentinel said
the space agency recruited former
FBI Director William Webster, also
a former federal judge, to act as
a mediator and adviser in negotiating
the out-of-court settlements. The
paper said its request yielded just
seven pages of documents that leave
many questions unanswered, including
exactly when the settlements occurred.
In an interview with the sentinel,
Webster, also a former CIA director,
said he was bound by confidentiality
and couldn't discuss details of the
agreements, but defended the process
as proper.
"The
members of the (survivors') families
wanted this to be a private matter,"
said Webster, a consulting partner
in Washington with the international
law firm of Milbank, Tweed, Hadley
& McCloy. "They were healing, and
they were ready to discuss, properly,
their rights.... Everyone felt it
had a better chance of coming together
without seeing their name in lights."
In brief written responses to sentinel
questions, NASA spokesman Allard Beutel
said little about the settlements,
citing family privacy. He said the
money came from the agency's budget
via a 2004 Congressional appropriation.
"The Columbia astronauts were our
friends and co-workers," Beutel wrote.
"Our concern always has been with
the crew's families and we didn't
announce details of the settlement
in an effort to protect the personal
privacy of the Columbia families."
Former NASA administrator Sean o'Keefe
and ex-general counsel Paul Pastorek,
who helped set up the settlement process,
did not return phone calls and e-mails,
the paper said. Jon Clark, widower
of astronaut Laurel Blair Salton Clark,
was quoted as saying NASA was "deferential"
in dealing with the families through
a turbulent period in their lives.
"We were in a state of shock," he
said. "To go the lawsuit route, it's
very painful and very protracted.
So we settled." Also killed were air
force Col. Rick husband, 45, mission
commander; Navy Cmdr. Willia, who
was the shuttle pilot; Navy capt.
David M. Brown, 46; Navy Cmdr. Clark,
41; and payload specialists air force
Lt. Col. Michael P. Anderson, 43;
and Israeli air force col. Ilan Ramon,
48, Israel's first astronaut. The
documents were released to the sentinel
last month after a reporter filed
requests in 2005 and 2006. Stephen
L. Mcconnell, NASA's principal FOIA
officer, insisted the agency was not
trying to delay the records release.
Five of the seven astronauts on Columbia
were military officers and barred
from suing the government because
they were on active duty while on
loan to NASA, making contractors likely
targets for lawsuits.

Ancient
diamonds found in Canada
|
| |
|
For
the first time, scientists have dated
diamonds from the recently discovered
diamond fields in Canada's Northwest
Territories and have found them to
be the oldest precisely dated diamonds
on Earth. They formed 3.5 billion
years ago in an era called the Archean
when the Earth was forming its first
continents. Other ancient continents,
such as in southern Africa or Siberia,
have long been known to have diamonds
almost as old, but none that have
been so precisely dated. The researchers,
including Steven Shirey and Richard
Carlson from the Carnegie Institution's
Department of Terrestrial Magnetism,
Kalle Westerlund, Stephen Richardson,
and John Gurney from the University
of Cape Town, and Jeffrey Harris from
the University of Glasgow, also report
evidence suggesting that the diamonds
formed during a process called subduction.
Subduction occurs when one crustal
plate sinks and slides under another
and is plunged hundreds of miles into
Earth's mantle. This conclusion documents
one of the oldest known examples of
modern plate tectonics. The findings
are published in the September issue
of Contributions to Mineralogy and
Petrology. "Diamonds aren't just for
spectacular jewelry," commented Shirey.
"They are scientific gems too. They
act as tiny time capsules. Many diamonds
encase tiny mineral grains-what jewelers
call impurities but geoscientists
call inclusions-that can tell us how
old the diamond is and what geologic
processes occurred in the deep Earth
billions of years ago." Diamonds,
dense forms of carbon, are the hardest
natural substance known. The largest
diamonds come from cratons-ancient
continental regions and their deep
roots that provided a nucleus around
which younger continental material
gathered. Cratons contain the oldest
rocks on the planet and hold much
of the Earth's mineral wealth, including
diamonds. Cratonic roots extend into
the mantle more than 125 miles (200
km) deep where pressure is high enough,
but temperature cold enough, for diamond
formation. The mantle "keels" to cratons
are as old as the overlying crust
and they date to the Archean period
(3.9 to 2.5 billion years ago). Rare
volcanic eruptions, of magmas that
solidify into rocks called kimberlites,
from depths of 95 to 125 miles (150
to 200 km) have brought diamonds to
the surface as passive passengers
in the exploding kimberlite magma.
Diamonds come in two major varieties:
eclogitic and peridotitic. Scientists
have believed for some time that eclogitic
diamonds, related to the high pressure
equivalents of basaltic crustal rocks,
form from the process of subduction.
But this study contains the first
evidence that the peridotitic diamonds,
which are in chemical equilibrium
with the peridotite of the Earth's
mantle, also may be formed from the
water and other fluids released by
subducting crustal plates at depth.

One
donor cornea may treat three patients
|
| |
|
An
Indian medical school study has determined
one donor cornea can be divided and
transplanted into multiple patients
with eye disease or eye damage. Recent
advances have allowed ophthalmologic
surgeons to move from transplanting
the entire cornea in every patient
to more focused operations that involve
removing and replacing only the diseased
or damaged portion of the cornea.
Such surgical techniques provide an
opportunity to make use of a single
donor cornea in more than one patient.
B In the study, Rasik Vajpayee --
then of the All India Institute of
Medical Sciences and now at the University
of Melbourne -- used a cornea from
a man who died of cardiac arrest for
transplants in three patients. The
corneal tissue was divided into three
parts, each part was then transplanted
into different patients. The procedures
were performed on the same day and
were all successful. The scientists
said the use of a single donor cornea
in more than one patient might become
standard surgical practice, helping
reduce the backlog of patients with
corneal blindness in countries in
which there is a dearth of good-quality
donor corneal tissue.

Rare
bird spotted after 140 yrs
|
| |
|
A
rare large-billed reed warbler, thought
to have been lost by ornithologists,
has been spotted in India after 140
years. Except for a single bird found
in the Sutlej valley in Himachal Pradesh
in 1867, it has not been sighted in
India since, Bombay Natural History
Society (BNHS) said here on Thursday.
The warbler was discovered by a team
of bird watchers in Kolkata, who say
they saw it feeding amid the bamboo
vegetation in Narendrapur on the outskirts
of the city. The wetland bird, smaller
than a house sparrow but with a longer
beak, has an olive-brown back with
a whitish underside, and "is drab
in appearance". From a distance one
could mistake it for a sparrow. Photos
of the bird were sent to BNHS to confirm
its identity and ornithologists identified
it from preserved specimens of other
warblers in its collection. The warbler's
identity was also confirmed by Delhi-based
Bikram Grewal, author of several books
on Indian birds. The bird was spotted
in Thailand in March last year after
130 years. Professor Steffan Bensch
of Sweden's Lund University had confirmed
the identity of the bird found in
Thailand using DNA testing. "Almost
nothing is known about this mysterious
bird. The Indian specimen has short,
round wings and we speculated it is
resident or short-distance migrant,
so its appearance in Thailand is very
surprising," Bensch had said.

Studies
prove harmful effects of violent videogames
on kids
|
| |
|
ISU
psychologists have recently released
a book which has proved the harmful
effects of violent video games on
kids and youth. The results published
in the book are based on the findings
of three different studies carried
out by the psychologists recently.
ISU distinguished Professor of Psychology
Craig Anderson, Assistant Professor
of Psychology Douglas Gentile, and
doctoral student Katherine Buckley
have shared the results of three new
studies in their book, "Violent Video
Game Effects on Children and Adolescents".
The first study found that even exposure
to children's violent video games
had the same short-term effects on
increasing aggressive behavior as
the more graphic teen (T-rated) violent
games. Almost 161 9- to 12-year-olds,
and 354 college students who participated
in the study were randomly assigned
to play either a violent or non-violent
video game. The participants subsequently
played another computer game designed
to measure aggressive behavior in
which the punishment levels were set
in the form of noise blasts to be
delivered to another person participating
in the study. Additional information
was also gathered on each participant's
history of violent behavior and previous
violent media viewing habits.
The
researchers found that participants
who played the violent video games
-- even if they were children's games
-- punished their opponents with significantly
more high-noise blasts than those
who played the non-violent games.
They also found that habitual exposure
to violent media was associated with
higher levels of recent violent behavior
-- with the newer interactive form
of media violence found in video games
more strongly related to violent behavior
than exposure to non-interactive media
violence found in television and movies.
"Even the children's violent video
games -- which are more cartoonish
and often show no blood -- had the
same size effect on children and college
students as the much more graphic
games have on college students," said
Gentile. "What seems to matter is
whether the players are practicing
intentional harm to another character
in the game. That's what increases
immediate aggression -- more than
how graphic or gory the game is."
The second study, which surveyed 189
high school students, found that participants
who had more exposure to violent video
games held more pro-violent attitudes,
had more hostile personalities, were
less forgiving, believed violence
to be more typical, and behaved more
aggressively in their everyday lives.
"We
were surprised to find that exposure
to violent video games was a better
predictor of the students' own violent
behavior than their gender or their
beliefs about violence," said Anderson.
"Although gender aggressive personality
and beliefs about violence all predict
aggressive and violent behavior, violent
video game play still made an additional
difference. "We were also somewhat
surprised that there was no apparent
difference in the video game violence
effect between boys and girls or adolescents
with already aggressive attitudes,"
he said. The thied study which analyzed
430 third-, fourth- and fifth-graders,
their peers, and their teachers twice
during a five-month period in the
school year, found that children who
played more violent video games early
in the school year changed to see
the world in a more aggressive way,
and became more verbally and physically
aggressive later in the school year.
Higher aggression and lower pro-social
behavior were in turn related to those
children being more rejected by their
peers. "I was startled to find those
changes in such a short amount of
time," said Gentile. "Children's aggression
in school did increase with greater
exposure to violent video games, and
this effect was big enough to be noticed
by their teachers and peers within
five months." The book's final chapter
gives "Helpful Advice for Parents
and Other Caregivers on Choosing and
Using Video Games." The authors say
that providing clear, science-based
information to parents and guardians
about the harmful effects of exposure
to violent video games is the first
step to educate the people who are
best able to use the information.

108
ft: That's height of devotion
|
| |
|
Taking
devotion to a new high, Delhiites
have got an all-new architectural
marvel which boasts of being the tallest
and the only automated idol of Lord
Hanuman in the world. Its developers
are now planning to make it to the
Guinness Book of World Records with
their creation. The towering Lord
Hanuman idol, which has been coming
up at Pusa Road roundabout over the
last 13 years, was thrown open to
public on Monday. The statue depicts
Lord Hanuman standing tall on the
severed head of a demon. Its height
is 108 feet (by comparison, the Qutab
Minar stands at 239 feet). "Hundred-and-eight
is Lord Hanuman's favourite number
- he chanted 108 times, ate 108 laddus
and took Lord Ram's name 108 times.
It is the tallest Hanumanji idol in
the world," said Om Prakash, general
secretary of the temple trust which
created the idol. The arms of the
idol open and close at the touch of
a button. "The movement is controlled
by a computer. When the arms open,
a trolley holding Ram and Sita idols
comes out of his heart. This is the
only such automated statue in the
world. The idols that come out are
plated with gold," he said.

NRIs
can now make use of Right to Information
Act
|
| |
|
The
Central Information Commission (CIC)
has ruled that Indian missions abroad
come under the purview of the Right
to Information Act, thus enabling
the 50 lakh NRIs to make use of it
too. At a meeting last week, the CIC
said since Indian missions were set
up by the External Affairs Ministry,
"they come under the ambit of the
RTI Act". It is not yet clear how
applicants approaching missions abroad
for information will pay the mandatory
fee. But the commission asked the
ministry and the Department of Personnel
and Training to find them a means
of doing so. In the interim, the commission
said Indian missions "would not have
the right to reject applications on
grounds of non-payment of fee". Information
Commissioner OP Kejariwal had asked
his colleagues for their opinion in
this matter when an Ahmedabad resident
wanted to know why a French national
who wanted to visit India was denied
a visa by the Indian mission in Paris.
