All living things are built from proteins created from the same 20 chemical units, called amino acids. Now, scientists at Cambridge are developing new ones.

A deadly outbreak of “superbug” salmonella sprung up in the US late last year. While this is certainly not the first time drug-resistant bugs have been found in the US, the outbreak marks yet another milestone on the road to a future without antibiotics.
Over 250 people across 32 states fell sick with a strain of Salmonella that’s resistant to multiple antibiotics between June 2018 and March 2019, according to a recent Morbidity and Mortality Weekly Report from the US Centers for Disease Control and Prevention (CDC). At least two people died from the infection, and a further 60 cases were so severe that they required hospitalization.
The outbreak of antibiotic-resistant Salmonella infections was linked back to beef bought in the US and a “Mexican-style soft cheese” obtained in Mexico. They found that the strain didn’t respond to ciprofloxacin and had “decreased susceptibility” to azithromycin, two of the main antibiotic drugs used to treat Salmonella infections. The unusual strain – known as Salmonella enterica serotype Newport – emerged no later than 2016 and is still continuing to spread among cattle.
When British futurist James Lovelock looks to the future, he doesn’t see humans ruling the Earth.
“Our supremacy as the prime understanders of the cosmos is rapidly coming to end,” he wrote in his new book “Novacene,” according to NBC News. “The understanders of the future will not be humans but what I choose to call ‘cyborgs’ that will have designed and built themselves.”

Intentional homicides are estimates of unlawful homicides purposely inflicted as a result of domestic disputes, interpersonal violence, violent conflicts over land resources, intergang violence over turf or control, and predatory violence and killing by armed groups. Intentional homicide does not include all intentional killing; the difference is usually in the organization of the killing. Individuals or small groups usually commit homicide, whereas killing in armed conflict is usually committed by fairly cohesive groups of up to several hundred members and is thus usually excluded.
