Urban heat islands make cities greener
...rs discovered that city climates have a noticeable influence
on plant growing seasons up to 10 kilometers (6 miles) away from a city's edges. Growing seasons in 70 cities in eastern North America were about 15 days longer in urban areas compared to rural areas outside of a city's influence. "If you live in a...
Scientists suggest framework for epigenetics in common disease

health and disease," says Andrew Feinberg, M.D., K...ditions. "The epigenetic marks a person has could influence
disease directly, but they also could affect whether an underlying genetic mutation or genetic varia...
Hunt for a new plant hormone points to carotenoids
...ade in the roots is able to travel up the plant to influence
branching in the shoot, suggesting that it may play a role in balancing root and shoot growth. In this issue of Current Biology, Ottoline Leyser and co-workers describe the identification of a gene that is essential for the synthesis of this novel ho...
Insecticide resistance: A constraint on evolutionary change

the ability of an organism to evolve such resistance at all. Identifying such specific and strong constraints on short-term evolutionary change are likely to help ecologists and public-health experts understand, and potentially predict, the ability o...
Good bacteria trigger proteins to protect the gut

the treatment of inflammatory bowel disease. "We know that bacteria play a detrimental role in these diseases, inducing a pathological inflammatory response. Often antibiotics are used in such cases as Crohn's disease, to eliminate gut bacteria. Howe...
Study by Tufts biologist provides window into progression of some degenerative diseases

repeat stability. "This is interesting because it still isn't understood why the repeat doesn't change size in some cell types, but is very unstable in others," Freudenreich said. For example, in Huntington's disease the repeat is prone to expansion ...
Researchers uncover surprising degree of large-scale variation in the human genome
