A new study led by paleoanthropologists reveals that Lucy’s species Australopithecus afarensis had an ape-like brain. However, the protracted brain growth suggests that — as is the case in humans — infants may have had a long dependence on caregivers.

A potential COVID-19 vaccine, delivered by microscopic needles, produces antibodies specific to the virus when tested in mice. This is the first peer-reviewed paper describing a COVID-19 vaccine candidate. The next step is a human clinical trial.

Chemists have created a hybrid system of bacteria and nanowires that captures energy from sunlight and transfers it to the bacteria to turn carbon dioxide and water into organic molecules and oxygen. On Earth, such a biohybrid could remove carbon dioxide from the atmosphere. On Mars, it would provide colonists with raw material to manufacture organic compounds ranging from fuels to drugs. The efficiency is greater than the photosynthetic efficiency of most plants.
