An acrylic sphere, which will be submerged in 35,000 tonnes of high-purity water, will further shield the detector from background radiation. (Qiu Xinsheng/VCG via Getty) | |||||
Inside China's underground neutrino labIf 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. Nature | 6 min read | |||||
Ecologists say 'Anthropocene' still mattersGeologists 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.

Roman skeleton hints at malaria's historyResearchers 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.

Question of the weekMost PhDs are assessed on their final dissertation — something that hasn't changed for decades. A Nature editorial earlier this week argued for reform, including more knowledge of education research and educational practice among doctoral supervisors. What do you think? If you have suggestions for specific changes, please send your ideas to briefing@nature.com. | |||||

How loneliness haunts astronautsIn his heartfelt documentary Space: The Longest Goodbye, director Ido Mizrahy explores first-hand accounts of how leaving family behind can wreak havoc on an astronaut's well-being. Interviews and candid videos offer a poignant look at the isolation and loss of connection that so many astronauts feel in space — and their advice for how to deal with it.

Why menopause keeps evolving in whalesComparing 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.
