Obama, Clinton unite at JFK's grave
Belief that single nutrients such as
omega-3s, sugar or salt can cure or
cause all ills is folly, a leading health
e key, Professor Stephen Simpson
says, is for people to think about food
as food and to seek a healthy balance
between protein, carbohydrates and
Too much of one for too long
can make you fat and unhealthy, or
even thin and unhealthy, Simpson,
academic director of the new
$500 million Charles Perkins
centre set up at the University of
Sydney to ght obesity, diabetes and
cardiovascular disease, said.
" e balance really matters," he told
colleagues at an Australian Society
for Medical Research conference in
His team conducted a study in
which 1000 mice were fed 30 di erent
diets with di erent ratios of protein,
carbohydrates and fat.
"If you want to lose weight as a
mouse, you go onto a high-protein
diet. But if you stay on that too long
you will have poor circulating insulin
and glucose tolerance.
"If you go too low on protein, you
will drive over-consumption and be
prone to obesity."
A good balance for a mouse is about
20% protein, about 60% carbohydrates
and about 20% fat.
"Mice are not that di erent from
humans," he said.
An interesting nding was that a
low-protein diet coupled with high
carbohydrates led to obesity. But
these mice lived longest and had a
healthy balance in their gut.
Simpson said that he was concerned
about the emphasis on micro-
nutrients such as vitamins, sugar and
"It is unhelpful when people argue
everything is the fault of sugar or
fat or salt or whatever when what
we are dealing with is a balancing
e best type of carbohydrates and
fat is limited amounts of sugar and
complex, low GI, hard-to-digest
Simpson said healthy fats such as
omega-3 were also important.

A meteorite found in the Sahara last
year by Bedouin tribesmen is a rock from
Mars, revealing that the Red Planet's
crust formed 4.4 billion years ago,
Sold to the elite club of meteorite
collectors, the extraordinary rock has
been analysed by United States and
ey found tough crystals within the
meteorite called zircons, which held
traces of uranium, whose rate of decay
can be used as a calculator of age.
e dating puts the meteorite at a
whopping 4.4 billion years old.
" is date is about 100 million years
after the rst dust condensed in the solar
system," Munir Humayun, a professor of
Earth, ocean and atmospheric science at
Florida State University, said.
"We now know that Mars had a crust
within the rst 100 million years of the
start of planet-building, and that Mars'
crust formed concurrently with the
oldest crusts on Earth and the moon."
e rock, measuring 40mm across
and weighing 84g, carries the o cial
designation of NWA 7533, with the
letters NWA meaning North-west
Africa, where it was found near Bir
Anzarane, in southern Morocco.
It has a sister, an even more famous
stone called NWA 7034, that has been
called "Black Beauty" --- its dark surface
indicating a volcanic basalt origin.
At least three other recovered
meteorites in the area are believed to
be part of a rock that came from Mars,
presumably dislodged by an asteroid that
whacked the planet's surface.
Using mass spectrometers at the
US national high magnetic eld
laboratory, the scientists also found high
concentrations in NWA 7533 of trace
metals such as iridium.
ese are typically found when a
planetary surface is pulverised by asteroid
bombardment, and soils in the impact
crater suddenly fuse in the heat.
e parent rock is likely to have
come from Mars' southern highlands,
according to the paper, published in the
" is cratered terrain has been long
thought to hold the keys to Mars' birth
and early childhood," Humayun said.
United States President Barack Obama, second from left, and former President Bill Clinton, second from right, escort Ethel Kennedy, widow
of Robert F Kennedy, to a wreath-laying ceremony in honour of assassinated President John F Kennedy at Arlington National Cemetery, near
Two Democratic presidents, Barack
Obama and Bill Clinton, have silently
honoured John F Kennedy at the former
United States leader's grave, marking the
50th anniversary of his assassination.
Obama and Clinton, along with First

dappled grave of JFK, who was gunned
down in Dallas on November 22, 1963.

since about 1975."

by about 5% per decade, leaving
youngsters about 15% less t in

"If a young person is generally

to develop conditions like heart
disease later in life," lead author
Grant Tomkinson, senior lecturer in
the University of South Australia's
School of Health Sciences, said.
" e most important type of tness
for good health is cardiovascular
tness, which is the ability to exercise
vigorously for a long time, like
running laps around an oval track."
e declines in cardiovascular
endurance performance went hand
in hand with individual countries'
measurements of average body fat
"About 30% to 60% of the declines
in endurance running performance
can be explained by increases in fat
mass," Tomkinson said.

Rupert Murdoch and his wife, Wendi
Deng Murdoch, appeared before
a Manhattan judge overnight in a
10-minute hearing that cleared the way
for ending their 14-year marriage.
"I'm glad you were able to resolve these
matters amicably," New York State Judge
Ellen Gesmer said to the media mogul
and his wife after asking if they were
satis ed with settlement.
After the session, Deng, dressed in a
dark-green coat and navy skirt, crossed
the courtroom to hug her soon-to-be
ex-husband, the chairman of News Corp
and 21st Century Fox.
Key details of the agreement were
not revealed, but a person familiar with
the terms of settlement said Deng is
expected to keep the couple's home
in Beijing and their Fifth Avenue
apartment in Manhattan, purchased in
2004 for a then-record $44 million.

Controversial grave-recycling laws
aimed at addressing a shortage of burial
space in Sydney have passed through the
New South Wales parliament.
e government has said the laws are
needed because burial space in Sydney is
set to run out within 30 to 40 years.
Small Business Minister Katrina
Hodgkinson said the legislation created
a "sound framework for the long-
term planning and management of all
cemeteries and crematoria in NSW".
"Renewable tenure burial will put
downward pressure on interment costs
and give people the option of a traditional
burial which is currently beyond the
means of some," Hodgkinson said.
Under the laws, rolling leases of a
minimum 25 years could be renewed for
up to 99 years.
If a lease is not renewed after two
years, a person's remains could be dug up
and the site reused --- either re-buried
deeper underground or moved to an
Hodgkinson said renewable tenure was
already operating in Waverley Cemetery
and the Sydney Natural Burial Park.
"It's one of many choices that will be
made available in a regulated manner,"

oversee rules for cemetery operators.

For months, curators at a British
museum had been wondering how
an ancient Egyptian statue in a
sealed display cabinet had been
able to rotate on its glass shelf,
seemingly of its own free will.
Rumours abounded that it was
cursed by an Egyptian god, or that
the spirit of its owner had entered
the gurine, causing it to shudder.
Others put forward more prosaic
explanations, suggesting a magnetic
eld was behind the statue's
But now, a British engineer has
solved the riddle, discovering that
miniscule vibrations from tra c
and footsteps from passersby were
causing the 3800-year-old stone
gurine to spin.
" e statue was rotating due to
vibrations entering the display
case," Steve Gosling told Reuters by
telephone overnight. "We installed
an accelerometer and found that
vibrations from both road tra c
and footfall within the museum
were the cause."
Video footage of the spinning
statue went viral on the internet
over the summer, drawing crowds
to the Manchester Museum in
northern England to gaze at the
Gosling, who made his discovery
as part of an ITV television series
called Mystery Maps, said the bulk
of the weight of the 25cm statue
was at one end, meaning it was o -
balance and especially susceptible
"With an object of such hard
material on a glass shelf, the level of
friction between the two materials
is very low. It doesn't take a lot to
make it move," he said.
e statue, of a man called Neb-
Senu, was intended as an o ering to
Osiris, ancient Egyptian god of the
dead and ruler of the under world.
It was donated to the museum by a
private c ollector some 80 years ago.
