Good news on multiple sclerosis and pregnancy
— 18:18 GMT | HealthThere is good news for women with multiple sclerosis (MS) who are pregnant or thinking about becoming pregnant. A new study shows that pregnant women with multiple sclerosis are only slightly more likely to have caesarean deliveries and babies with a poor prenatal growth rate than women who do not have MS…
Hidden threat: Elevated pollution levels near regional airports
— 18:18 GMT | EnvironmentScientists are reporting evidence that air pollution - a well-recognised problem at major airports - may pose an important but largely overlooked health concern for people living near smaller regional airports. Those airports are becoming an increasingly important component of global air transport systems. The study, one of only a handful to examine airborne pollutants near regional airports, suggests that officials should pay closer attention to these overlooked emissions, which could cause health problems for local residents. It appears online in ACS' Environmental Science and Technology, a semi-monthly journal…
Saliva proteins change as women age
— 18:13 GMT | HealthIn a step toward using human saliva to tell whether those stiff joints, memory lapses, and other telltale signs of ageing are normal or red flags for disease, scientists are describing how the protein content of women's saliva change with advancing age. The discovery could lead to a simple, noninvasive test for better diagnosing and treating certain age-related diseases in women, they suggest in a report in ACS' Journal of Proteome Research, a monthly publication. These diseases include lupus, Sjoegrens syndrome (associated with dry mouth and dry eye), and other immune-related disorders that affect millions of women worldwide, often at higher rates than in men…
Secondhand smoke exposure worse for toddlers, obese children
— 18:08 GMT | HealthToddlers and obese children suffer more than other youth when exposed to secondhand smoke, according to research presented at the American Heart Association's Scientific Sessions 2009…
Asthma a significant risk factor for complications in children with H1N1
— 18:03 GMT | HealthA new study on paediatric H1N1 influenza admissions has found that asthma is a significant risk factor for severe disease in children with pandemic H1N1 compared with the seasonal flu. The study, led by researchers from The Hospital for Sick Children (SickKids) in Toronto, Ontario, is published online today in Canadian Medical Association Journal…
Developing 'green' tires that boost mileage and cut carbon dioxide emissions
— 17:58 GMT | ChemistryA new generation of 'green' automobile tires that can boost fuel efficiency without sacrificing safety and durability is rolling their way through the research pipeline. The new tires could help add an extra mile or two per gallon to a car's fuel economy. That's the topic of the cover story of the current issue of Chemical and Engineering News, (C and EN) ACS' weekly newsmagazine…
New on-off 'switch' triggers and reverses paralysis in animals
— 17:53 GMT | ChemistryIn an advance with overtones of Star Trek phasers and other sci-fi ray guns, scientists in Canada are reporting development of an internal on-off 'switch' that paralyses animals when exposed to a beam of ultraviolet light. The animals stay paralysed even when the light is turned off. When exposed to ordinary light, the animals become unparalysed and wake up. Their study appears in the Journal of the American Chemical Society…
Toward explaining why hepatitis B hits men harder than women
— 17:48 GMT | HealthScientists in China are reporting discovery of unusual liver proteins, found only in males, that may help explain the long-standing mystery of why the hepatitis B virus (HBV) sexually discriminates - hitting men harder than women. Their study has been published online in ACS' Journal of Proteome Research, a monthly publication…
Drug for erectile dysfunction improves heart function in young heart-disease patients

Berkeley Lab lends expertise to India to promote energy efficiency
— 17:38 GMT | TechnologyIndia may rank only a distant fourth in terms of carbon dioxide emissions, behind China, the United States and Russia, but its rapid economic growth rate coupled with ageing and inefficient energy infrastructure suggest dire environmental consequences if 'business as usual' continues. That's why experts from the Lawrence Berkeley National Laboratory have been working to expand collaborations with India on energy efficiency…
