Swedish researchers discover world's oldest poisoned arrows

Researchers from Sweden and South Africa have found traces of poison on arrowheads dating back 60,000 years in southern Africa. This marks the oldest known use of poisoned arrows to date. The poison comes from the plant gifbol, also known as giftlök in Swedish.

In a collaboration between researchers from South Africa and Sweden, traces of poison have been identified on quartz arrowheads found in southern Africa. These traces date back 60,000 years, surpassing the previous record of 35,000 years for the use of poisoned arrows.

The poison originates from the South African plant gifbol (known as giftlök in Swedish), which early humans used to poison their arrows. The discovery highlights the advanced thinking of early humans.

"It is the result of a long and close collaboration between researchers in South Africa and Sweden. Being able to identify the world's oldest arrow poison together has been a major effort and is incredibly encouraging for further research," says Sven Isaksson, professor at Stockholm University, in a press release.

"Using arrow poison requires planning, patience, and understanding of cause and effect. It is a clear sign of advanced thinking in early humans," adds Anders Högberg, professor at Linnaeus University.

The study is published in the journal Science Advances and underscores the importance of international collaboration in archaeology.

The United Kingdom, France, Germany, Sweden and the Netherlands said laboratory analyses found traces of epibatidine — a toxin associated with South American poison dart frogs — in samples linked to the late Russian opposition leader Alexei Navalny, and said Russia had the means, motive and opportunity to administer it while he was imprisoned. Moscow has repeatedly denied wrongdoing in Navalny’s death.

One person has been detained on suspicion of attempted murder after four employees at Uppsala's Akademiska hospital are suspected of being poisoned. They fell ill suddenly in late October with similar symptoms and low potassium levels. Prosecutor Emma Häggström is leading the investigation, which began in November.

A 20-year study in Bangladesh has found that reducing arsenic levels in drinking water was associated with as much as a 50 percent reduction in deaths from heart disease, cancer and other major chronic illnesses. Researchers followed nearly 11,000 adults and reported that participants who switched to safer wells eventually had mortality risks similar to people who were never heavily exposed to arsenic. The findings, published in JAMA, underscore the global health benefits of tackling arsenic contamination in drinking water.
