People could “live inside a machine” by turning their brain into a program code once a computer capable of recreating some 100 trillion connections is built. “People could probably live inside a machine. Potentially, I think it is definitely a possibility,” Dr Hannah Critchlow of the Cambridge Neuroscience.

Obesity may take greater toll on men

Speeding up tests for antibiotic resistant bacteria

Tests for antibiotic resistance can take up to three days to come back from the lab, hindering doctors’ ability to treat bacterial infections quickly. But now researchers at the University of Toronto have designed a small and simple chip to test for antibiotic resistance in just one hour, giving doctors a shot at picking the most effective antibiotic to treat potentially deadly infections.

New human ancestor species from Ethiopia

An international team of scientists, led by Dr. Yohannes Haile-Selassie of The Cleveland Museum of Natural History, has discovered a 3.3 to 3.5 million-year-old new human ancestor species. Upper and lower jaw fossils recovered from the Woranso-Mille area of the Afar region of Ethiopia have been assigned to the new species Australopithecus deyiremeda. This hominin lived alongside the famous “Lucy’s” species, Australopithecus afarensis.

The new species is the most conclusive evidence for the contemporaneous presence of more than one closely related early human ancestor species prior to 3 million years ago. The species name “deyiremeda” (day-ihreme-dah) means “close relative” in the language spoken by the Afar people.

ICT Improves Sesame farming

Researchers say while mobile technology has proved useful in communicating information such as crop prices and weather information to smallholder farmers in eastern Africa, it has been largely untested in agricultural extension services. As such, Allowing farmers to view interactive training modules on tablet computers in local language increases knowledge and convenience compared to traditional demonstration farms.
