Presently, there are about 40 million Americans over the age of 65, with the fastest-growing segment of the population over 80 years old. Traditionally, aging has been viewed as a period of progressive decline in physical, cognitive and psychosocial functioning, and aging is viewed by many as the "number one public health problem" facing Americans today.

40 years after the last Apollo spacecraft launched, readings from the Apollo 14 and 15 dust detectors have been restored by scientists with the National Space Science Data Center (NSSDC) at NASA's Goddard Space Flight Center. 

The newly available data will make long-term analysis of the Apollo dust readings possible. Digital data from these two experiments had not been archived before, and it's believed that roughly the last year-and-a-half of the data have never been studied. The recovery of these data sets is part of the Lunar Data Project, an ongoing NSSDC effort, drawing on researchers at multiple institutions, to make the scientific data from Apollo available in modern formats.

The CoBalT study aimed to determine the best 'next step' treatment for people whose depression had not responded to medication alone.

Maybe it is time for Moore's Light to take over? 

Whether or not different species of early humans interbred and produced offspring of mixed ancestry - hybridization - has been the subject of recent studies but the findings are not universally accepted.
