Papaya and pineapple juices facilitate rehydration of mummified dermal tissue for fingerprint capture.

Mummified remains pose an issue for forensic scientists as identification of the deceased can be difficult due to extreme shriveling of dermal tissue and a resulting lack of quality fingerprint features. The typical protocols used to address this problem include corrosive chemicals that may further damage the already susceptible tissues. An alternative approach is found in the juice of two fruit species known to contain proteolytically active enzymes that tenderize soft tissues, thereby promoting water uptake.

A Genetically Informed Longitudinal Study of Loneliness and Dementia Risk in Older Adults.

Although several studies have shown small longitudinal associations between baseline loneliness and subsequent dementia risk, studies rarely test whether change in loneliness predicts dementia risk. Furthermore, as both increase with advancing age, genetic and environmental selection processes may confound the putative causal association between loneliness and dementia risk. We used a sample of 2,476 individual twins from three longitudinal twin studies of aging in the Swedish Twin Registry to test the hypothesis that greater positive change in loneliness predicts greater dementia risk.
