Flower forms in the primrose: Biologists unlock 51.7-million-year-old genetic secret to landmark Darwin theory
Scientists have identified the cluster of genes responsible for reproductive traits in the common primrose flower (Primula vulgaris), first noted as important by Charles Darwin more than 150 years ago. Darwin hypothesized that some plant species with two distinct forms of flower, where male and female reproductive organs were of differing lengths, had evolved that way to promote out-crossing by insect pollinators.

Large-scale changes in insect species inhabiting streams and rivers
The frequencies of occurrence of hundreds of insect species inhabiting streams have been altered relative to the conditions that existed prior to wide spread pollution and habitat alteration, American scientists have discovered. Results were similar for the two study regions (the Mid-Atlantic Highlands and North Carolina), where frequencies of occurrence for more than 70 percent of species have shifted.

Gut microbes promote motor deficits in a mouse model of Parkinson's disease
Gut microbes may play a critical role in the development of Parkinson's-like movement disorders in genetically predisposed mice, researchers report. Antibiotic treatment reduced motor deficits and molecular hallmarks of Parkinson's disease in a mouse model, whereas transplantation of gut microbes from patients with Parkinson's disease exacerbated symptoms in these mice. The findings could lead to new treatment strategies for the second most common neurodegenerative disease in the United States.

Human kidney progenitors isolated, offering new clues to cell renewal

In a first-of-its-kind look at human kidney development, researchers at The Saban Research Institute of Children's Hospital Los Angeles have isolated human nephron progenitor (NP) cells. Their results, published online in the journal Stem Cell Translational Medicine, will help scientists understand how these progenitor cells become renal cells in the developing fetus, and possibly offer a future way to foster renal regeneration after chronic kidney failure or acute injury.

Study reveals how ionising radiation damages DNA and causes cancer

For the first time, researchers from the Wellcome Trust Sanger Institute and their collaborators have been able to identify in human cancers two characteristic patterns of DNA damage caused by ionising radiation. These fingerprint patterns may now enable doctors to identify which tumours have been caused by radiation, and investigate if they should be treated differently.

Giraffes more speciose than expected

Scientists from the Senckenberg and the Giraffe Conservation Foundation have analysed the genetic relationships of all major populations of giraffe in the wild. The large study on the genetic makeup of giraffe, published today in Current Biology, shows that there are four distinct giraffe species. Until now, only one giraffe species had been recognized. The unexpected results are based on analyses using several nuclear marker genes of more than 100 animals. The new insights are set to improve protection efforts of these endangered animals in Africa.

Open-source tools accelerate plant breeding in developing countries
Crop breeders in developing countries can now access free tools to accelerate the breeding of improved crops varieties, thanks to a collaboration between the GOBII project at Cornell University and the Boyce Thompson Institute (BTI), and the James Hutton Institute in Scotland.

Oldest zoo gorilla set to have biopsy before 60th birthday
The oldest known gorilla living in a zoo, a female named Colo, is slated to undergo a surgical biopsy sometime before her 60th birthday on Dec. 22.
