Brazil: Dam Collapse Leaves 300 Missing

Brazilian Authorities are pessimistic for the 300 people who remain missing after a dam collapse on Friday. Also Australians are celebrating their national day today, but for many Aboriginal people it brings up emotional memories of the country’s colonial past. And violence against robots is apparently on the rise, which has researchers searching for the reasons.
