As many as 153 million premature deaths linked to air pollution could be avoided worldwide this century if governments speed up their timetable for reducing fossil fuel emissions, a new Duke University-led study finds.

This year’s unexpectedly aggressive flu season reminds everyone that although the flu vaccine can reduce the number of people who contract the virus, it is still not 100 percent effective. Researchers report that a tweak to a small-molecule drug shows promise for future production of new antiviral therapies that could help patients, regardless of the strain with which they are infected.

The world drinks a lot of wine, and that means a lot of grapes are consumed every year. But not every part of the grape ends up in the bottle. Seeds, stalks and skins — roughly a quarter of the grapes —- are typically discarded in landfills as waste. But now, researchers say they have found some useful commercial applications, such as prolonging the shelf life of fatty foods, for these wine leftovers.

As climate change increases the risk to trees from severe storms, insects, diseases, drought and fire, a Rutgers University study highlights the need for improved safety in tree-care operations.

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.

Spurred on by climate change, international travel and international trade, disease-bearing insects are spreading to ever-wider parts of the world.

This means that more humans are exposed to viral infections such as Dengue fever, Chikungunya, Zika, West Nile fever, Yellow fever and Tick-borne encephalitis.

For many of these diseases, there are as yet no specific antiviral agents or vaccines.

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.

In a new application of gene-editing technology, researchers at the Stanford University School of Medicine have gleaned insights into the genetic underpinnings of amyotrophic lateral sclerosis, a neurodegenerative disease that’s notoriously tricky to parse.

In a study conducted in rural India, Johns Hopkins Medicine researchers working in collaboration with Bal Umang Drishya Sanstha (BUDS), a nonprofit Indian organization focused on child health, have found that mobile phone reminders linked with incentives such as free talk time minutes work better than phone alerts alone to improve childhood immunization rates in poor communities.

The prevalence of diabetes has increased almost 10-fold in China since the early 1980s, with one in 10 adults in China now affected by diabetes. Although adiposity is the major modifiable risk factor for diabetes, other research in China suggests this can explain only about 50% of the increase in diabetes prevalence over recent decades, suggesting other lifestyle factors, including smoking, may play a role in the aetiology of diabetes. In recent decades, there has been a large increase in cigarette smoking in China, especially among men. About two thirds of Chinese men now smoke, consuming roughly 40% of the world’s cigarettes.
