Researchers at Caltech have developed a prototype miniature medical device that could ultimately be used in "smart pills" to diagnose and treat diseases. A key to the new technology—and what makes it unique among other microscale medical devices—is that its location can be precisely identified within the body, something that proved challenging before.

NASA's Aqua satellite measured cloud top temperatures in newly formed Tropical Depression 15E in the Eastern Pacific Ocean and found some strong storms. 

A new study has demonstrated the potential to use a frequency distribution-based index of brain functional connectivity as a biomarker for detecting Alzheimer's disease and mild cognitive impairment (MCI). These new findings, which show the index of functional connectivity to have good accuracy across databases and test sites, are published in Brain Connectivity, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Brain Connectivity website until October 13, 2017.

NASA calculated the rainfall left in the wake of now post-tropical cyclone Irma as it moved through the Caribbean Sea to landfall in Florida and then captured a night-time look at the storm as it moved over Georgia.

A spruce forest regeneration experiment in Interior Alaska that spanned nearly 30 years demonstrates which forest management practices produce the best results.
