LONDON, Feb 17 (Reuters) – Financial markets may be more
vulnerable to traders’ stress levels than previously thought,
according to a scientific study which found that high levels of
the stress hormone cortisol can induce risk aversion.
The findings, which turns on its head the assumption that
traders appetite for risk-taking remains constant throughout
market up and downs, suggests stress could in fact make them
more cautious, exacerbating financial crises just at a time when
risk-taking is needed to support crashing markets.
LONDON (Reuters) – A year after they revealed a twisted skeleton found under a car park as the mortal remains of King Richard III, scientists in Britain plan to grind samples of his ancient bones and use them to map his genome.
The project, which may alter perceptions of the last king of England to die in battle more than 500 years ago, aims to learn about Richard’s ancestry and health, and provide a genetic archive for historians, researchers and the public.
LONDON (Reuters) – Researchers have found a gene linking intelligence to the thickness of so-called “grey matter” in the brain, and say their discovery could help scientists understand how and why some people have learning difficulties.
An international team of scientists analyzed DNA samples and brain scans from more than 1,500 healthy 14-year-olds and gave them a series of tests to establish their verbal and non-verbal intelligence.
LONDON, Feb 10 (Reuters) – Children with cancer are being
denied access to potentially life-saving medicines because
European Union rules allow drug firms to waive the need to test
some drugs in paediatric trials, researchers said on Monday.
Calling for a loophole in EU legislation to be closed,
scientists and specialists in childhood oncology led by
Britain’s Institute for Cancer Research (ICR) said changing the
rules could extend or save many young lives.
LONDON, Feb 10 (Reuters) – Setting a minimum alcohol price
of 45 pence ($0.73) a unit in Britain would cut deaths and
hospital time among heavy drinkers yet have virtually no adverse
impact on the pockets of moderate drinkers, researchers said on
In a study which calls into question a government decision
last year to drop plans to set a minimum price for alcohol,
researchers found it would have the greatest effect on the 5
percent of people who drink at rates classified as “harmful”.
LONDON, Feb 5 (Reuters) – The death of a woman in China from
a strain of bird flu previously unknown in humans is a reminder
of the ever-present potential pandemic threat from mutating
animal viruses, scientists said on Wednesday.
The new strain, called H10N8, has so far infected only two
people – a fatal case in a 73-year-old and another in a woman
who is critically ill in hospital. But the fact it has jumped
from birds to humans is an important warning, they said.
LONDON (Reuters) – Gaming enthusiasts across the world can from Tuesday join the search for cancer cures with a citizen science project using a smartphone game to help researchers analyze vast volumes of genetic data from tumor samples.
Called “Play to Cure: Genes in Space”, the spaceship game is designed for smartphones and was launched by the charity Cancer Research UK (CRUK), which hopes it will speed up the decoding of data to reveal patterns of the genetic faults that cause cancers to grow and spread.
LONDON, Feb 3 (Reuters) – Governments must make better use
of vaccines and preventative public health policies in the fight
against cancer as treatment alone cannot stem the disease, a
World Health Organisation (WHO) agency said on Monday.
The WHO’s International Agency for Research on Cancer (IARC)
said cancer was growing “at an alarming pace” worldwide and new
strategies were needed to curb the sometimes fatal and often
LONDON (Reuters) – A quarter of all Russian men die before they reach their mid-fifties and their passion for alcohol – particularly vodka – is largely to blame, according to research published on Friday.
A study of more than 150,000 people found extraordinarily high premature death rates among male Russians, some of whom reported drinking three or more bottles a week of the potent clear spirit.
LONDON, Jan 29 (Reuters) – In experiments that could open a
new era in stem cell biology, scientists have found a simple way
to reprogramme mature animal cells back into an embryonic-like
state that allows them to generate many types of tissue.
The research, described as game-changing by experts in the
field, suggests human cells could in future be reprogrammed by
the same technique, offering a simpler way to replace damaged
cells or grow new organs for sick and injured people.
