The Iceman mummy had a high-fat meal of wild goat, red deer and wheat before he died on a glacier about 5,300 years ago, according to findings published in Current Biology. The mummy's stomach, which moved during the mummification process, was only recently found.

A large, dark sarcophagus has been found in a tomb in Alexandria, Egypt, alongside the bust of a man who may be the person sealed in the sarcophagus. The sarcophagus appears not to have been opened yet, and scientists may opt to scan the container without opening it to prevent damage.
Researchers with the South Pole's IceCube Neutrino Observatory have tracked a cosmic neutrino back to its source, according to a pair of studies published online in Science. The neutrino hails from a distant elliptical galaxy known as TXS 0506+056.
A pair of experimental drugs that block a pathway of immune responses has improved the health of study participants who were 65 or older, findings published in Science Translational Medicine suggest. "This study is the first step to suggest we may be able to target some of the fundamental pathways contributing to aging to promote healthy aging, including healthy immune function, in older people," said Joan Mannick, the study's co-author.
Salt marshes in southeast England could start to disappear beginning in 2040 due to sea-level rises, according to a study published in Nature Communications. "Quantifying the vulnerability of marshes to sea level rise is essential if the threat is to be mitigated over the coming decades," said researcher Ian Shennan.
Researchers found no clear evidence that vitamin D has a protective effect against Alzheimer's disease, multiple sclerosis, Parkinson's disease or other neurodegenerative diseases, but they say exposure to the sun's ultraviolet rays, independent of vitamin D production, may have a neuroprotective benefit. The findings of the review, which included 73 studies, were reported in the journal Nutritional Neuroscience.
Researchers at the University of California at San Diego School of Medicine found that the prevalence of mild cognitive impairment diagnoses among middle- to late-middle-aged men who had previously received cognitive testing rose twofold after accounting for practice effects, which were significant in most cognitive domains. The findings in the journal Alzheimer's & Dementia: Diagnosis, Assessment & Disease Monitoring suggest that longitudinal studies involving older adults should be corrected for practice effects, researchers said.
Greenhouse panel manufacturer Adapt8 has been awarded a $50,000 grant from Marion County, Ore., to build a test greenhouse where new products and systems can be tested. Construction on the greenhouse is expected to begin before the end of the year.
