Anti-bacterial wipes pointless as bugs grow back in 20 minutes, scientist says

Anti-bacterial wipes only eradicate bacteria from kitchen surfaces for 20 minutes and using them to keep germs at bay is “an absolutely redundant” exercise, a scientist has said.  Dr Clare Lanyon, a biomedical scientist from Northumbria University in Newcastle upon Tyne, said consumers may be wasting money on antibacterial wipes and sprays because common germs, which can replicate themselves in just 20 minutes, quickly recolonise back to original mass even

How to get children to eat greens: Use more stick and less carrot, study finds

Parents should not reward their children for eating greens, researchers said after discovering that youngsters who are not praised for trying vegetables are more likely to eat them eventually. The best way to get children to eat food they do not like is simply to give them repeated exposure to it, the study found. In tests, children repeatedly offered vegetables were more likely to eventually eat them as opposed to

Low-carb diets 'no better' than traditional focus on fat

Increasingly trendy low-carbohydrate diets are no more effective than traditional low-fat diets, scientists have said. A new study involving more than 600 overweight adults found both worked similarly well if adhered to strictly for a year. Dieting strategies which focus on carbohydrates have come into vogue in recent years and have won the backing of celebrities from Jennifer Aniston to Mick Jagger. But last night experts said the research showed

Autism blood discovery promises earlier tests and treatment

Scientists have discovered evidence of autism in the blood of affected children in a breakthrough that promises earlier testing and treatment for the condition. A team at Warwick University found that those suffering from the developmental disorder were more likely to have damaged blood proteins. Affecting around one in every 100 people in the UK, autism spectrum disorder (ASD) can be difficult to diagnose, particularly in the early stages of

Did Neanderthals' poor art ability contribute to their extinction?

Neanderthals, as the name suggests, were not great thinkers, and consequently their occasional forays into cave drawing left a lot to be desired. But while the dubious artistic prowess of these prehistoric cousins to early humans may not seem of much importance, new research has found it is closely related to their inferior hunting skills and may ultimately explain why they became extinct. Analysis of charcoal drawings and engravings by

Ovarian cancer can be passed on via fathers - and it strikes younger

Ovarian cancer can be passed on to women via their fathers, scientists have established for the first time. New genetic research has finally answered why some sets of sisters share a higher risk of developing the disease than that of their mother. Ovarian cancer, described as the “silent killer”, is the fourth most deadly form in the UK, claiming around 4,100 lives a year of 7,400 new cases diagnosed. It

Stroke risk greater for children who are short growing up - new study

Short children are at greater risk of suffering a stroke later in life, according to new research. Being two to three inches shorter growing up raised the likelihood of the disease in both men and women. The discovery follows research by British scientists showing the vertically challenged are at increased risk of a heart attack. The latest findings were based on more than 300,000 Danish schoolchildren born between 1930 and

Asthma 'blue' inhalers linked to infertility - new study

Asthmatic women who use commonly available inhalers are more likely to become infertile, a new study suggests. Analysis of more than 5,000 women found users of the blue “reliever” inhaler, which is intended to ease symptoms once they have presented, had a 30 per cent increased risk of failing to conceive within a year. By contrast, use of the the brown preventative inhaler was not linked to any additional fertility

Ants armies use human-style battlefield medicine and treat each others' open wounds  - new study

Ant armies employ a system of battlefield evacuation and emergency medicine similar to that used by humans, researchers have discovered. Groundbreaking new observations of mass raids on termite colonies revealed the open wounds of injured ants are swiftly tended to by comrades in a bid to save them for future attacks. Described in the journal Proceedings of the Royal Society B, the behaviour is the first such example discovered anywhere

New Alzheimer's drug offers hope for end to 'terrifying' psychosis affecting half of all patients

A new drug promises to spare hundreds of thousands of Alzheimer’s sufferers from “terrifying” hallucinations and paranoia, researchers have announced. Scientists have successfully tested the first medicine capable of treating psychosis, which affects around half of patients with the disease, without the devastating side-effects caused by current drugs. Published in the Lancet Neurology, the trial of pimavanserin offers particular hope to those with advanced psychosis, which doctors often describe as
