What can a pesticide pump, a jar full of sand, or an old calico print tell us about the Anthropocene—the age of humans? Just as paleontologists look to fossil remains to infer past conditions of life on earth, so might past and present-day objects offer clues to intertwined human and natural histories that shape our planetary futures. In this era of aggressive hydrocarbon extraction, extreme weather, and severe economic disparity, how might certain objects make visible the uneven interplay of economic, material, and social forces that shape relationships among human and nonhuman beings?Future Remains is a thoughtful and creative meditation on these questions. The fifteen objects gathered in this book resemble more the tarots of a fortuneteller than the archaeological finds of an expedition—they speak of planetary futures. Marco Armiero, Robert S. Emmett, and Gregg Mitman have assembled a cabinet of curiosities for the Anthropocene, bringing together a mix of lively essays, creatively chosen objects, and stunning photographs by acclaimed photographer Tim Flach. The result is a book that interrogates the origins, implications, and potential dangers of the Anthropocene and makes us wonder anew about what exactly human history is made of.

This paper briefly reviews the evidence for multistore theories of memory and points out some difficulties with the approach. An alternative framework for human memory research is then outlined in terms of depth or levels of processing. Some current data and arguments are reexamined in the light of this alternative framework and implications for further research considered.

Symptoms of mercury toxicity, biochemical changes, and blood/urine mercury levels were evaluated in a small group of patients. Six patients attending Delek Hospital, Dharamsala, India, taking mercury-containing traditional Tibetan medicine (TTM) (Group I), were compared with three patients taking non-mercury containing TTM (Group II) and healthy volunteers(Group II). Quantitative estimation of mercury ingestion based on chemical analysis was compared with US regulatory standards.RESULTS: Group I were significantly older (mean 55 years+/-SE 6.4) range 26-69 years, than Group II (26.7 years+/-SE 5) range 17-34 years and Group III (32.5 years +/-SE 0.5) range 33-34 years (P =0.05). Group I took TTM on average for 51 months and had a mean of 2.5 non-specific, mercury-related symptoms. Group I had higher mean diastolic pressures (85 mmHg) than Group II (73 mmHg) (P=0.06) and more loose teeth. Mean daily mercury intake for Group I was 674 microg, estimated as 10 microg/kg per day. (Established reference dose for chronic oral exposure: 0.3 microg/kg per day.) Blood mercury levels were non-detectable, but mean urinary mercury levels for Group I were 67 microg/L (EPA levels <20 microg/L). Renal and liver function tests were not significantly different between groups and within normal clinical range. CONCLUSIONS: Prolonged ingestion of mercury containing TTM is associated with absent blood levels, but relatively high urinary levels. Further studies are needed to evaluate toxicity and therapeutic potential.

Both aqueous and methanolic fractions derived from the Tibetan preparation PADMA-28 (a mixture of 22 plants) used as an anti-atherosclerotic agent, and which is non-cytolytic to a variety of mammalian cells, were found to strongly inhibit (1) the killing of epithelial cells in culture induced by 'cocktails' comprising oxidants, membrane perforating agents and proteinases; (2) the generation of luminol-dependent chemiluminescence in human neutrophils stimulated by opsonized bacteria; (3) the peroxidation of intralipid (a preparation rich in phopholipids) induced in the presence of copper; and (4) the activity of neutrophil elastase. It is proposed that PADMA-28 might prove beneficial for the prevention of cell damage induced by synergism among pro-inflammatory agonists which is central in the initiation of tissue destruction in inflammatory and infectious conditions.
