Blombos Cave is an archaeological site located in Blomboschfontein Nature Reserve, about 300 km east of Cape Town on the Southern Cape coastline, South Africa. The cave contains Middle Stone Age (MSA) deposits currently dated at between c. 100,000 and 70,000 years Before Present (BP), and a Late Stone Age sequence dated at between 2000 and 300 years BP. The cave site was first excavated in 1991 and field work has been conducted there on a regular basis since 1997, and is ongoing.
The excavations at Blombos Cave have yielded important new information on the behavioural evolution of anatomically modern humans. The archaeological record from this cave site has been central in the ongoing debate on the cognitive and cultural origin of early humans and to the current understanding of when and where key behavioural innovations emerged among Homo sapiens in southern Africa during the Late Pleistocene. Archaeological material and faunal remains recovered from the Middle Stone Age phase in Blombos Cave – dated to ca. 100,000–70,000 years BP – are considered to represent greater ecological niche adaptation, a more diverse set of subsistence and procurements strategies, adoption of multi-step technology and manufacture of composite tools, stylistic elaboration, increased economic and social organisation and occurrence of symbolically mediated behaviour.
The most informative archaeological material from Blombos Cave includes engraved ochre, engraved bone ochre processing kits, marine shell beads, refined bone and stone tools and a broad range of terrestrial and marine faunal remains, including shellfish, birds, tortoise and ostrich egg shell and mammals of various sizes.[20][21][22] These findings, together with subsequent re-analysis and excavation of other Middle Stone Age sites in southern Africa, have resulted in a paradigm shift with regard to the understanding of the timing and location of the development of modern human behaviour.

In this episode, Sidney talks about how Gemini GEL got started and grew into the organization it is today, sharing stories about the artists he’s worked with along the way.
In 1966, at the age of forty-one, Sidney Felsen moved from the world of accounting to that of art, founding the artists’ workshop and fine-art print publisher Gemini GEL in Los Angeles. With Gemini GEL, Sidney quickly got to work with some of the biggest artists of the twentieth century: Man Ray, Josef Albers, Jasper Johns, and Robert Rauschenberg, to name a few. And Gemini GEL continues its work with new generations of artists, including Julie Mehretu, Tacita Dean, and David Hammons.
“The finding in two randomised trials that advice to use ibuprofen results in more severe illness or complications helps confirm that the association seen in observational studies is indeed likely to be causal. Advice to use paracetamol (acetaminophen) is also less likely to result in complications.”
Ian Jones, a professor of virology at the University of Reading, said that ibuprofen’s anti-inflammatory properties could “dampen down” the immune system, which could slow the recovery process. He added that it was likely, based on similarities between the new virus (SARS-CoV-2) and SARS I, that covid-19 reduces a key enzyme that part regulates the water and salt concentration in the blood and could contribute to the pneumonia seen in extreme cases. “Ibuprofen aggravates this, while paracetamol does not,” he said.
At First Light chronicles twenty-six extraordinary artists of the last two hundred years who have lived and worked in Maine. Published to coincide with the state’s bicentennial in 2020, the volume considers the significant contributions artists have made to a deeper and more profound understanding of Maine’s history, its land and its peoples. Maine’s unique and breathtaking landscape–from its rugged coastline, quaint harbors, majestic mountains, and verdant forests–continues to have a powerful effect on the artists who are drawn to its shores.
