| Woman aquires new accent after stroke. Rare case of foreign-accent syndrome reported in Canada. |
| A woman in southern Ontario is one of the first cases in Canada of a rare neurological syndrome in which a person starts speaking with a different accent, McMaster University researchers report in the July issue of the Canadian Journal of Neurological Sciences. |

| YOUR NEIGHBORHOOD CAN AFFECT YOUR HEALTH |
| Research shows middle-aged and elderly people in poor neighborhoods 'significantly more likely' to suffer mobility and cognitive problems.
Research carried out at the Peninsula Medical School, South West England, has found strong links between neighbourhood deprivation and the physical and intellectual health of older people. |

| COMMON AQUATIC ANIMALS SHOW EXTREME RESISTANCE TO RADIATION. FINDING COULD STIMULATE NEW STUDY OF FREE RADICALS’ ROLE IN INFLAMMATION, CANCER, AGING. |
| Scientists at Harvard University have found that a common class of freshwater invertebrate animals called bdelloid rotifers are extraordinarily resistant to ionizing radiation, surviving and continuing to reproduce after doses of gamma radiation much greater than that tolerated by any other animal species studied to date. |

| BONN SCIENTISTS DISCOVER NEW HEMOGLOBIN TYPE. INSTRUMENTS FALSELY REPORT ANOXIA IN AFFECTED PEOPLE. |
| Scientists at the University of Bonn have discovered a new rare type of haemo-globin. Haemoglobin transports oxygen in the red blood corpuscles. When bound to oxygen it changes colour. The new haemoglobin type appears optically to be transporting little oxygen. Measurements of the blood oxygen level therefore present a similar picture to patients suffering from an inherited cardiac defect. |

| CHILDREN WITH HEALTHIER DIETS DO BETTER IN SCHOOL. A NEW STUDY REVEALS THAT CHILDREN WITH HEALTHY DIETS PERFORM BETTER IN SCHOOL. |
| A new study in the Journal of School Health reveals that children with healthy diets perform better in school than children with unhealthy diets. |

| HOW ONE PEST ADAPTED TO LIFE IN THE DARK |
| A type of beetle that lives its entire life burrowing through stored grain has been found to lack full colour vision, and what’s more the vision it does have breaks the rules. Most other insects have trichromatic vision – they are sensitive to ultraviolet, blue and long wavelength light. In a report published in the online open access journal Frontiers in Zoology, scientists reveal that this beetle has lost photoreceptors that are sensitive to blue wavelengths. |

| A HELPING HAND FROM THE ‘GRANDPARENTS’ |
| A team of scientists led by the University of East Anglia has discovered the existence of ‘grandparent’ helpers in the Seychelles warbler – the first time this behaviour, which rarely occurs except in humans, has been observed in birds. |

| WHY DIVING MARINE MAMMALS RESIST BRAIN DAMAGE FROM LOW OXYGEN |
| No human can survive longer than a few minutes underwater, and even a well-trained Olympic swimmer needs frequent gulps of air. Our brains need a constant supply of oxygen, particularly during exercise. Contrast that with Weddell seals, animals that dive and hunt under the Antarctic sea ice. They hold their breath for as long as 90 minutes, and remain active and mentally alert the whole time. The seals aren't fazed at all by low levels of oxygen that would cause humans to black out. What's their secret? |

| CAT FLEAS' JOURNEY INTO THE VACUUM IS A 'ONE-WAY TRIP' |
| Homeowners dogged by household fleas need look no farther than the broom closet to solve their problem. Scientists have determined that vacuuming kills fleas in all stages of their lives, with an average of 96 percent success in adult fleas and 100 percent destruction of younger fleas. |
