LONDON (Reuters) – Older people at risk of dementia who follow advice on healthy eating, exercise and brain-training can slow down cognitive decline, particularly in their ability to organize and regulate thought processes, researchers said on Thursday.
In the first randomized controlled trial of its kind, the scientists found that two years of intensive guidance for people aged 60 to 77 led to some striking differences in the brain’s capabilities in so-called executive function and processing.
LONDON, March 11 (Reuters) – A wave of H7N9 bird flu in
China that has spread into people may have the potential to
emerge as a pandemic strain in humans, scientists said on
The H7N9 virus, one of several strains of bird flu known to
be able to infect humans, has persisted, diversified and spread
in chickens across China, the researchers said, fuelling a
resurgence of infections in people and posing a wider threat.
LONDON/GENEVA (Reuters) – Final stage trials of an Ebola vaccine being developed by Merck and NewLink Genetics will begin in Guinea on March 7, the World Health Organization said on Thursday.
Signaling global health authorities’ determination to see through trials despite a sharp drop in cases in the West Africa epidemic, the WHO said a second shot, developed by GlaxoSmithKline will be tested “in a sequential study, as supply becomes available”.
LONDON (Reuters) – British scientists are turning to crowdfunding to complete the first scientific study ever to image the brain of someone “tripping” on the psychedelic drug LSD.
The study, part of a psychedelic research project the scientists say could revolutionize understanding of the human brain, is led by neuroscientists at Imperial College London who now need around 25,000 pounds ($38,000) to finish their work.
LONDON, March 4 (Reuters) – Scientists who analysed
countless chemicals in spider venom say they have identified
seven compounds that block a key step in the body’s ability to
pass pain signals to the brain.
In research they said could one day lead to a new class of
potent painkillers, the scientists focused on 206 species of
spider and searched for molecules in the venom that block nerve
activity, particular via so-called “Nav1.7 channels”.
LONDON, Feb 27 (Reuters) – A team of scientists said on
Friday they had found “robust evidence” that a condition called
Chronic Fatigue Syndrome (CFS) is a biological as opposed to a
psychological disorder, but some experts questioned the
The team from Columbia University in the United States
identified in their research distinct immune changes in patients
with CFS — markers they said pointed to distinct disease stages
and would lead to better diagnosis and treatment.
LONDON (Reuters) – The world remains highly vulnerable to a possible severe flu pandemic and governments should increase surveillance, vigilance and preparedness, the World Health Organization (WHO) said on Friday.
“Nothing about influenza is predictable – including where the next pandemic might emerge and which virus might be responsible,” the United Nations health agency warned.
LONDON (Reuters) – EU rules that prevent genetically modified crops from being grown in the UK, even after they pass rigorous safety tests, are not fit for purpose and should be totally reformed, British lawmakers said on Thursday.
Members of parliament’s science and technology committee said the EU regulation is driven more by politics than science.
LONDON, Feb 25 (Reuters) – The World Health Organization in
Europe called on Wednesday for measles vaccination campaigns to
be stepped up across the region after recording 22,000 cases of
the highly infectious disease since the start of 2014.
Saying she was “taken aback” by high case numbers, Zsuzsanna
Jakab, the U.N. health agency’s European director, said the
22,149 reported cases from seven countries threatened the
region’s goal of eliminating measles by the end of 2015.
LONDON, Feb 25 (Reuters) – People diagnosed with major
depression are around three times more likely than the general
population to commit violent crimes such as robbery, sexual
offences and assault, psychiatric experts said on Wednesday.
In a study based on some 47,000 people, the scientists
emphasised, however, that the overwhelming majority of depressed
people are neither violent nor criminal and should not be
