More Arctic sea ice is entering the North Atlantic Ocean than before, making it increasingly dangerous for ships to navigate those waters in late spring, according to new research led by the University of Manitoba.

Three University of Victoria researchers have been awarded a total $935,000 in federal funding to study the impact of underwater noise on endangered southern resident killer whales and the chinook salmon they depend on for almost 80 per cent of their diet.  

As Tropical Cyclone Eliakim was strengthening on its way to landfall in Madagascar the Global Precipitation Measurement mission, or GPM, core satellite found very heavy rainfall occurring in the tropical storm.

Nature is rife with symbiotic relationships, some of which take place out of sight, like the rich underground exchange of nutrients that occurs between trees and soil fungi.

Tropical Cyclone Marcus has developed off the coast of Australia’s Northern Territory along the Cobourg Peninsula coast. NASA’s Aqua satellite provided a view of the new storm from its orbit in space.

NASA has powered on its latest space payload to continue long-term measurements of the Sun's incoming energy.

On the seafloor of the shallow coastal regions north of Siberia, microorganisms produce methane when they break down plant remains. If this greenhouse gas finds its way into the water, it can also become trapped in the sea ice that forms in these coastal waters. As a result, the gas can be transported thousands of kilometres across the Arctic Ocean and released in a completely different region months later. This phenomenon is the subject of an article by researchers from the Alfred Wegener Institute, published in the current issue of the online journal Scientific Reports. Although this interaction between methane, ocean and ice has a significant influence on climate change, to date it has not been reflected in climate models.

Metastasis is the process whereby a tumour that grows in one organ breaks away from it and travels to another organ and colonises it. In the colonisation process it needs to create new blood vessels through which the cancer cells obtain the nutrients and oxygen they need to grow. This blood vessel formation process is called angiogenesis and is carried out by the endothelial cells. "Unlike normal endothelial cells and due to the signals, that reach them from the tumour cells, the cells that supply the tumours have increased growth and tend to move towards the metastatic mass to help it grow,” said Iker Badiola, member of the Signaling Lab research group in the Department of Cell Biology and Histology of the UPV/EHU’s Faculty of Medicine and Pharmacy.

  In years when food is abundant for squirrels, males kill the young of rival males, according to new research from University of Alberta biologists.

Researchers in the University of Calgary Faculty of Veterinary Medicine (UCVM) have developed a fast, portable and inexpensive way to test humans and animals for different types of chronic and infectious diseases. This new “point of care” method tests for signals of infection, such as specific antibodies, in blood, milk or saliva samples.
