If all goes to plan, the US$376 million Jiangmen Underground Neutrino Observatory (JUNO) in China will be ready to start detecting by the end of this year. It is the frontrunner in a race to determine which type of neutrino has the highest mass and which has the lowest, one of the biggest mysteries in physics. Nature’s intrepid reporter Gemma Conroy donned her hard hat and took the 15-minute cable-car ride underground to take a look.

Geologists might have voted against creating a new epoch called ‘Anthropocene’ in recognition of humans’ impact on the planet, but that hasn’t stopped the term from taking on a life of its own. For many people across the arts and sciences, the word captures the extent to which we have altered the world and helps to define our relationship with Earth. “It’s a term that belongs to everyone,” says palaeoecologist Jacquelyn Gill.

Researchers have identified the first near-complete mitochondrial genome sequence of the pathogen that causes the deadliest form of malaria from an ancient Roman skeleton. They extracted the DNA of Plasmodium falciparum from the teeth of a Roman who lived in Italy in the second century AD. They were able to identify 5,458 pieces of unique genetic information that they combined to get a sequence covering 99.1% of the mitochondrial genome.

Comparing data on toothed whale species that do, and do not, experience menopause suggests that prolonged female postreproductive life allows whales to improve their offsprings’ and grand-offsprings’ survival chances. Older female whales such as killer whales (Orcinus orca) share food and become “repositories of long-term ecological knowledge”, explains animal-behaviour researcher and study co-author Sam Ellis. Menopause also seems to reduce reproductive competition between mothers and daughters. The hormone changes killer whales go through are similar to those in menopausal humans, but “as to hot and cold flushes, we’ve got no way of telling yet”, Ellis says.
