Peralta said he last saw Adams at a dinner gathering about six weeks ago.

"He was the first person to show up at the dinner table, which was remarkable, and he was drinking hot tea, which was even more remarkable," he said. "He had really turned a corner."The DST-NRF Centre of Excellence for Palaeoscience funded researchers based in the School of Geography, Archaeology and Environmental Studies and in the Evolutionary Studies Institute of the University of the Witwatersrand have used fossil pollen records to solve an on-going debate regarding invasive plant species in eastern Lesotho.

Their study, Chrysocoma ciliata L. (Asteraceae) in the Lesotho Highlands: an anthropogenically introduced invasive or a niche coloniser?, published in Biological Invasions, confirms that a shrub believed to be an invasive in the eastern Lesotho Highlands has been growing in the region for over 4,000 years.
