Someone in the developing world - particularly in rural Africa - dies from a rabid dog bite every 10 minutes.
The long-held belief that older people perform slower and worse than younger people has been proven wrong. In a study published today in Neuron, psychologists from McMaster University discovered that the ageing process actually improves certain abilities: Older people appear to be better and faster at grasping the big picture than their younger counterparts.
Gigantic eagles swooping from the skies to rescue Frodo and Sam in the Lord of the Rings may not be just the stuff of legends and fairytales, according to research published in the journal PloS Biology. McMaster University anthropologist Michael Bunce has shed new light on the evolution of the extinct Haast's eagle, the giant bird that once ruled the skies over New Zealand. Weighing between 20 and 30 pounds, the enormous Haast's Eagle dominated its environment. It was 30 to 40 per cent heavier than the largest living bird of prey around today, the Harpy Eagle of Central and South America.
A major Canadian-led global study has found that the vast majority of heart attacks may be predicted by nine easily measurable factors and that these factors are the same in virtually every region and ethnic group worldwide. The INTERHEART study looked at more than 29,000 people in 52 countries and from all inhabited continents of the world. The study found that the two most important risk factors are cigarette smoking and an abnormal ratio of blood lipids (Apolipoprotein B/Apolipoprotein A-1), which together predicted two-thirds of the global risk of heart attack.
Mirrored walls are a regular feature of gym d?cor, but new research suggests that the reflections may make some women feel worse after their workouts. A study published in Health Psychology found that sedentary women who exercised in front of a mirror for 20 minutes felt less energized, less relaxed and less positive and upbeat than women who performed their workout without a mirror. Women who exercised without the mirror also reported that they were less physically exhausted at the end of their workout, while those with a mirror reported no change in their exhaustion level.
