Before coins were re-introduced, goods or services were priced in multiples of fives because but since the death of coins and the near extinction of some Naira notes, price levels have been affected greatly, which means no goods could be bought for 1 Naira because no such denomination is available, so lowest-priced goods stayed at 5 Naira and Naira 10 Naira. Is there any possibility that coins or the denominations fast going out of circulation will return stronger in the nearest future?

Advances in genetic engineering are reviving the idea of de-extinction, or whether to bring back extinct animals to try to save endangered ecosystems. But is it really a good idea? What would be the unforeseen consequences of such an act? We speak to Ben Lamm, CEO of the American startup Colossal, which has just raised $15 million to revive the woolly mammoth.
