The world's elderly population is booming. The number of older people -- those age 60 years or older -- is expected to more than double by 2050 and is growing faster than all younger age groups across the globe. This...
A new high-throughput, miniature, portable sequencing technique* has been developed in recent years, for human and animal health purposes. It uses mobile laboratories to diagnose viruses such as Ebola or Zika almost instantly, in the field. Diagnosis is both...
If only we could keep our bodies young, healthy and energetic, even as we attain the wisdom of our years. New research at the Weizmann Institute of Science suggests this dream could be at least partly obtainable in the...
Two proteins central to the pathology of Alzheimer's disease act as prions -- misshapen proteins that spread through tissue like an infection by forcing normal proteins to adopt the same misfolded shape -- according to new UC San Francisco...
As we age, our bodies undergo biological changes that cause a decline in the function of our cells and tissues. However, most studies attempting to identify molecules involved age-related dysfunctions have focused only on mechanisms based on mRNA transcription,...
Patients undergoing long-term treatment with steroids may suffer from metabolic side effects. Researchers at the Helmholtz Zentrum M√ľnchen and the Ludwig Maximilians University of Munich (LMU), partners in the German Center for Diabetes Research (DZD), have now pinpointed a...

A new study from the University of Eastern Finland shows that a moderately high intake of dietary cholesterol or consumption of up to one egg per day is not associated with an elevated risk of stroke. Furthermore, no association...
University of Montana researchers have published new insights in the journal Science on how bacteria cause infections, which may help with future infection treatments. Rather than studying bacteria, the researchers studied viruses that infect pathogenic bacteria, known as bacteriophages, as...
