Dental
detection competence send heads home

Waikato University
researcher, Nicky Cameron, has road-tested record she
says could be used to brand a origins of preserved
Maori heads — including many of those being returned to New
Zealand from abroad museums.

She has tested
tiny amounts of finish on a teeth of brushtail possums,
using them as a indication class to uncover that a technology
could be used to accumulate a database for identifying the
geographical origins of Maori stays – including those
stored during Te Papa.

Preserved heads — famous as toi moko or upoko tuhi — and
other tellurian stays such as skeletons and bones, famous as
koiwi tangata, are kept during a Museum of New Zealand, which
actively pursues repatriations from museums and other
institutions in Europe and North America.

The museum has
had as many as 500 koiwi tangata and has recovered about 85
of a hundreds of recorded heads suspicion to have been kept
in unfamiliar museums. There have been 360 earnings of remains
from 13 countries and another 20 toi moko from French
museums are approaching to be handed behind to Te Papa
representatives in Paris on Monday.

Ms Cameron,
a chemistry tyro who wrote her masters thesis on a research,
collected possum teeth from around a country, because
enamel on teeth is laid down in a initial few years of life
for many mammals, afterwards stays mostly unchanged. Many
pre-European Maori lived all their lives in a one area and
ate customarily internal food – as possums do now – so in both cases
trace minerals in a teeth should be dynamic by mineral
levels in their region’s food and water.

She used laser
ablation inductively joined plasma mass spectrometry
(LA-ICP-MS) and analysed finish for patterns in a levels
of sodium, magnesium, phosphorus, calcium, manganese, zinc,
strontium and barium.

“This methodology shows
considerable intensity for use in identifying geographical
origins of tellurian stays within New Zealand alone or as an
adjunct to other techniques,” pronounced a authors of a paper
based on her research, only published in a Journal of Pacific Archeology.

Ms Cameron’s supervisor, Professor Ngahuia Te Awekotuku
– another author of a investigate – has formerly described
the proceed as “really critical and exciting” since it
could assistance lapse to their home areas “items of a sensitive
nature” being sent behind from abroad museums.

Synthetic oestrogen: a next
generation
American women women who were unprotected in the
womb to a damaging fake oestrogen are taking authorised movement over their doubled
risk of breast cancer.

A comparison Dunedin educational and
researcher, Professor Charlotte Paul, wrote a 2006 report on New Zealanders’
exposure to a drug diethylstilbestrol (DES), that was
known here as Stilboestrol, emanate in 2006. She told a SMC
about 600 New Zealand women were prescribed Stilboestrol as
a post-coital contraceptive, or to conceal lactation,
mainly in a 1940s and 1950s, and into a 1960s. American
regulators warned in 1971 opposite a use during pregnancy.

Last year, a investigate in a New England Journal of Medicine
indicated an augmenting risk of 12 medical conditions for
women who were unprotected in a womb to a drug, , including
a 40 times larger risk of building a cancer of the
vagina, called transparent dungeon adenocarcinoma (CCA), and nearly
double a risk of breast cancer.

The pre-trial court
hearing during Boston in a USA — due to finish today — is believed
to be a initial vital lawsuit alleging a couple between the
drug and some breast cancers in “DES daughters” over a age
of 40.

“We estimated 600 unprotected (NZ) women in 1984 and
considered that a vital underestimate,” Professor Paul told a SMC. “It competence be 1000 to
2000. It is a theory now. The mothers have an augmenting risk
of breast cancer, a daughters of CCA and breast cancer,
and really ordinarily constructional abnormalities of the
reproductive tract and hence problem with childbearing.
The sons have some reproductive tract
abnormalities”.

Kiwi MenzB work aids global
vaccine
Health experts perplexing to get a hold on
Meningococcal B illness in high-income countries and regions
such as South America are trialling a new broad-spectrum
vaccine, partly formed on pioneering work that grown the
MeNZB vaccine to control New Zealand’s meningococcal B
epidemic in 2004-5.

New research, only published in a
leading medical biography The Lancet, drew on that
vaccine specifically grown to fight a meningococcal B
epidemic in New Zealand in a 1990s and early 2000s, which
killed 185 people and putrescent some-more than 4000.

A million
young New Zealanders were vaccinated between 2004 and 2008
as a widespread waned naturally, The vaccine was targeted to
the aria present in New Zealand, so could not be used
as a concept vaccine, yet some of a bacterial components
it targeted have now been incorporated in a 4CMenB vaccine
providing shield to all variants of meningococcal B
serotype.

The latest clinical trial, formed in Chile, shows
that, after dual or 3 doses, blood samples from 99-100
per cent of recipients indicated insurance from
meningococcal B infection.

Questions still to be answered embody how
many strains it will strengthen against, how prolonged the
protection will final and either it will stop a bacteria
from being upheld on to others, providing indirect
protection to people not vaccinated.

First vast appropriation round
looms

The Ministry of Science and Innovation (MSI)
says it will deposit adult to $59.5 million
in a initial vital investment turn to support investigate from
discovery by to application.

MacDiarmid Institute
director, Associate Professor Kathryn McGrath pronounced currently it
will be a initial poignant contestable appropriation turn in
over dual and a half years from MSI or a bequest Foundation
for Research and Technology (FRST).

“During this period
there have been no opportunities in a earthy sciences to
apply for estimable appropriation of new programmes and there
has been a poignant change in a concentration of a Government
with courtesy to scholarship and innovation,” she pronounced in a
newsletter. “This, joined with a changes in a amount
of income accessible in any of a appropriation categories and the
large series of bids now all entrance to an finish during a same
time, rather than in a staggered fashion, is going to have
significant ramifications via a earthy sciences
community.

” The subsequent few months will be mad for the
many scientists operative on bids. The outcomes of these
bidding rounds will change a lay of a land for many in
science in New Zealand.”

The southern and eastern forests of a Amazon — once seen

researchers say. Though a Amazon is volatile to
individual disturbances, such as drought, multiple
disturbances such as land-use change, logging and glow have
overwhelmed this resilience, augmenting a disadvantage of
forest ecosystems.
