LONDON (Reuters) – Exposure to pollution from diesel exhaust fumes can disrupt honeybees’ ability to recognize the smells of flowers and could in future affect pollination and global food security, researchers said on Thursday.
In a study published in the Nature journal Scientific Reports, scientists from Britain’s University of Southampton found that the fumes change the profile of the floral odors that attract bees to forage from one flower to the next.
LONDON (Reuters) – Exercise may be just as good as medication to treat heart disease and should be included as a comparison when new drugs are being developed and tested, scientists said on Wednesday.
In a large review published in the British Medical Journal, researchers from Britain’s London School of Economics and Harvard and Stanford universities in the United States found no statistically detectable differences between exercise and drugs for patients with coronary heart disease or prediabetes, when a person shows symptoms that may develop into full-blown diabetes.
LONDON (Reuters) – Assessment tools used to predict how likely a psychopathic prisoner is to re-offend if freed from jail are “utterly useless” and parole boards might just as well flip a coin when deciding such risks, psychiatrists said on Tuesday.
Publishing a study that found risk score tools are only around 46 percent accurate on how likely psychopathic convicts are to kill, rape or assault again, they said probation officers and judges should set little or no store by such tests.
AMSTERDAM, Sept 30 (Reuters) – The world faces a rapidly
growing burden of cancer which will overwhelm governments unless
the medical and pharma industry takes the lead on a
multi-billion dollar private-public fund, oncologists said on
In a report on how rates of cancer diagnosis and death are
rising across the world while access to diagnosis and treatment
is extremely patchy, experts described the economics of the
problem as daunting and current financing models as broken.
AMSTERDAM (Reuters) – An experimental Roche drug that seems to work particularly well against lung cancer in smokers may be a “game changer” for these normally difficult-to-treat patients, researchers said on Sunday.
Presenting detailed data from an early-stage trial of the drug, called MPDL3280A, in patients with a form of the disease called non-small cell lung cancer (NSCLC), investigators said what they had found was “great news for lung cancer patients”.
AMSTERDAM (Reuters) – European governments should divert funds to routine bowel cancer tests from less effective breast and prostate screening programs, scientists said on Saturday, presenting what they called “irrefutable” evidence that bowel screening saves lives.
Many governments devote significant funds to breast cancer screening, but studies in recent years have found that routine breast mammograms can also lead to so-called “over-diagnosis” when tests pick up tumors that would not have caused a problem.
AMSTERDAM, Sept 27 (Reuters) – A new generation of drugs
designed to trigger the immune system to fight cancer is
offering the prospect of a “clinical cure” for some melanoma
skin cancer patients who until a few years ago were more likely
to be facing a swift death.
Cancer specialists gathering for a European conference at
the weekend said the so-called immunotherapy drugs, a class led
by Bristol-Myers Squibb’s Yervoy, or ipilimumab, have
transformed an area of oncology in which until recently doctors
barely had time to get to know their patients.
LONDON (Reuters) – The global rate of HIV infection and the number of AIDS-related deaths have been dramatically reduced, thanks to expanding access to treatment, the United Nations said in a report issued on Monday.
In its annual update on HIV, which it said now infects around 35.3 million people worldwide, UNAIDS said deaths from AIDS and HIV infection rates were falling, while the number of people getting treatment is going up.
LONDON (Reuters) – Valerie Curtis is fascinated by faeces. And by vomit, pus, urine, maggots and putrid flesh. It is not the oozing, reeking substances themselves that play on her mind, but our response to them and what it can teach us.
The doctor of anthropology and expert on hygiene and behaviour says disgust governs our lives – dictating what we eat, wear, buy, and even how we vote and who we desire.
LONDON (Reuters) – Genetic analysis of samples of the deadly MERS virus that has killed 58 people in the Middle East and Europe shows the disease has jumped from animals to humans several times, scientists said on Friday.
At least 132 people have been infected with the Middle East Respiratory Syndrome (MERS) coronavirus since it emerged about a year ago, and it has killed 58 of them, according to the World Health Organisation.
