Sensing Diseases From Space

Disease itself may be invisible to the human eye, but conditions ripe for disease outbreaks can be seen from satellites. ORNL’s Assaf Anyamba has spent his career using satellite images to determine where extreme weather may lead to vector-borne disease outbreaks. His work has helped the U.S. government better prepare … [continued]

Climate Change May Enable Antibiotic-Resistant Bacteria To Flourish

Experts already know that climate change has become a significant threat to global public health, particularly as rising temperatures have produced greater populations of disease-transmitting insects, such as mosquitoes. But warmth also encourages bacteria to grow, providing them a chance to mutate and elude drugs that once easily killed them. While antibiotic resistance is believed largely due to the indiscriminate prescribing of antibiotics, experts now think that other environmental stresses — climate change among them — also may be at work.

Revved-Up Sand Could Purify Water

First there was the Life Straw.  Then there was the Aquaduct Tricycle.  Now ordinary sand could provide an answer to one of the thorniest problems of the future: how to purify drinking water for the many millions of people who don’t have access to a clean, disease-free source — and … [continued]
