More research needed on diet and environmental influences on childhood asthma
— 15:31 GMT | HealthAsthma is one of the world's most common chronic diseases, affecting as many as 300 million people. It is estimated that by 2025 there could be an additional 100 million people with the disease. This rapid increase in asthma is most likely due to changing environmental or lifestyle factors, and over the last 15 years, changing diet has emerged as a promising contributor. Two studies published in the in the February 2011 issue of the Journal of the American Dietetic Association explore the possible relationship between nutrition and asthma. Researchers review the rationale for investigating associations between diet and asthma, discuss the potential for dietary intervention to complement conventional asthma treatment, and summarise the recent data suggesting that diet may influence the development of asthma…
Anti-oestrogen medication reduces risk of dying from lung cancer
— 15:28 GMT | HealthA new study has found that tamoxifen, an anti-oestrogen breast cancer medication, may reduce an individual's risk of death from lung cancer. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the study supports the hypothesis that there is a hormonal influence on lung cancer and that oestrogen levels play a role in lung cancer patients' prognosis…
Faster development might have its costs
— 15:25 GMT | BiologyFast development is often perceived as an advantage, as it enables better harmony with one's environment and readiness to cope with the challenges that it poses. However, research conducted at the University of Haifa, Israel, and University of California, Santa Cruz, and published in the scientific journal PLoS ONE, found that the acceleration of developmental rate incurs potentially lethal physiological costs for the developing individual. 'Our findings are consistent with research findings on other animals and call for further research on rates of development in humans,' said Asaf Sadeh who led the study…
Blocking rogue gene could stop the spread of most cancers
— 15:22 GMT | HealthScientists at the University of East Anglia (UEA) have discovered a rogue gene which - if blocked by the right drugs - could stop cancer in its tracks…

IU study: Humans' critical ability to throw long distances aided by an illusion
— 15:16 GMT | HealthCan't help moulding some snow into a ball and hurling it or tossing a stone as far into a lake as you can? New research from Indiana University and the University of Wyoming shows how humans, unlike any other species on Earth, readily learn to throw long distances. This research also suggests that this unique evolutionary trait is entangled with language development in a way critical to our very existence…
Scientists used accelerated evolution to develop enzymes that provide protection against nerve gas
— 15:13 GMT | HealthProtection against nerve gas attack is a significant component of the defence system of many countries around the world. Nerve gases are used by armies and terrorist organisations, and constitute a threat to both the military and civilian populations, but existing drug solutions against them have limited efficiency…
