More virus infection, please
Scientists have generated a new plasmid-based reverse genetics system for rotaviruses.

Hammerhead shark migration gives new hope for conservation
Great Hammerhead sharks have been tagged and tracked across the USA and Bahamas in a bid to shed light on their migration habits. Researchers suggest that these sharks are more at risk than previously thought because of their predictable and seasonal migratory patterns. As an endangered species, the Great Hammerhead shark is in desperate need of effective conservation management. This new information will allow marine planners to improve the protection of this iconic animal.

How proteins reshape cell membranes
Small 'bubbles' frequently form on membranes of cells and are taken up into their interior. The process involves EHD proteins. Scientists have now shed light on how these proteins assemble on the surface of a cell and reshape its membrane.

Watching birds near your home is good for your mental health -- official
(University of Exeter) People living in neighborhoods with more birds, shrubs and trees are less likely to suffer from depression, anxiety and stress, according to research by academics at the University of Exeter, the British Trust for Ornithology and the University of Queensland.

Dietary prebiotics improve sleep, buffer impacts of stress, says study
(University of Colorado at Boulder) New research suggests that lesser-known gut-health promoters called prebiotics -- which serve as food for good bacteria inside the gut -- can also have an impact, improving sleep and buffering the physiological impacts of stress.

Many genetic changes can occur early in human development
(Baylor College of Medicine) Multiple genetic changes can occur before or early after conception.

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.

International collaboration working to enhance protections for spinner dolphins
An international study involving researchers from Western Australia and the United States has unlocked a key behavioural schedule in spinner dolphins, which could provide crucial insight to conservation measures for the free-ranging animals.

Video: Tracking data and shark behaviour
Animals often share space as they move through their environment. Capturing these aggregations and co-occurrence events has proven extremely difficult in elusive, wide-ranging animals.

Tremors in newborn piglets attributed to previously unidentified virus
Symptoms of tremors and shaking in newborn piglets are not a sign that the animals are cold, but rather that they are suffering from a specific viral infection. Researchers at Vetmeduni Vienna have now been able to prove this correlation for the first time using a newly developed test. The scientists detected a previously unknown virus, termed atypical porcine pestivirus (APPV), in "shaking piglets", making it possible to clearly diagnose the potentially fatal disease. The virus remains in the animals for a long time following an infection and may also be transmitted sexually. The findings were published in the journal Veterinary Research.
