Ocean channel in Bahamas marks genetic divide in Brazilian free-tailed bats
Brazilian free-tailed bats are expert flyers, capable of migrating hundreds of miles and regularly traveling more than 30 miles a night. But they pull up short at a narrow ocean channel that cuts across the Bahamas, dividing bat populations that last shared an ancestor hundreds of thousands of years ago.

How immature cells grow up to be red blood cells
Researchers have identified the mechanism behind red blood cell specialization and revealed that it is controlled by an enzyme called UBE2O. This finding could spark the development of new treatments for blood disorders and cancers.

Mineral layer around avian flu pathogen may be the cause for human infections
Avian flu can be transmitted from birds to humans; transmission among humans, however, is limited. The reason may be an eggshell-like mineral layer that the virus acquires due to the high calcium concentration in the intestines of birds. These mineralized viruses are significantly more infectious and, in addition, more robust and heat stable than the native viruses.

New Bioimaging technique is fast and economical
(Rensselaer Polytechnic Institute) A new approach to optical imaging makes it possible to quickly and economically monitor multiple molecular interactions in a large area of living tissue -- such as an organ or a small animal; technology that could have applications in medical diagnosis, guided surgery, or pre-clinical drug testing.

Research reveals how physical exercise protects the heart
(Fundação de Amparo à Pesquisa do Estado de São Paulo) A study by the University of São Paulo (USP) in Brazil, published recently in the journal Autophagy, helps to elucidate part of the mechanism whereby aerobic exercise protects the sick heart. The benefits of exercise range from prevention of cachexia -- severe loss of weight and muscle mass -- and control of arterial blood pressure to improved cardiac function, postponing a degenerative process that causes progressive heart cell death. About 70% of heart failure patients die from the condition within five years.

The proteins that domesticated our genomes

EPFL scientists have carried out a genomic and evolutionary study of a large and enigmatic family of human proteins, to demonstrate that it is responsible for harnessing the millions of transposable elements in the human genome. The work reveals the largely species-specific gene-regulatory networks that impact all of human biology, in both health and disease.

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.

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.
