A multitude of multiverses
Excitingly, scientists say that alternative universes are allowed by physics. We find out about the leading multiverse theories, and establish whether they could harbour an alternate version of you.

Blobs of human brain cells cultivated in the lab, known as brain organoids or “mini-brains”, are transforming our understanding of neural development and disease. Now, researchers are working to make them more like the real thing

Bizarre sea creatures, a new view of the ocean, the race to the moon, and more
We humans may think of ourselves, or possibly beetles, as typical Earthlings, but to a first approximation, life on Earth exists in the sea. And what spectacular life! Our special package on the oceans is teeming with images of eerie, delicate, elaborate, glowing and occasionally kind of frightening creatures that have rarely been seen by terrestrial species. The in-depth report was guided by sustainability senior editor Mark Fischetti along three main themes: mystery, discovery and surprise.

Although the domestic dog can trace its origins to the grey wolf (Canis lupus), exactly when, where and how domestication happened has remained a source of debate. In this week’s issue, Anders Bergström, Pontus Skoglund and their colleagues, take a step towards resolving this question. The researchers analysed the genomes of 72 ancient wolves from across Europe, Siberia and North America, and spanning the past 100,000 years. They found that dogs are most closely related to ancient wolves from eastern Eurasia but that dogs in the Near East and Africa derive
up to half their ancestry from a distinct population related to modern southwest Eurasian wolves. Although none of the genomes analysed was a direct match for either dog ancestry, the researchers say that it has narrowed down where next to look for the ancestors of domestic dogs.

The cover shows an artistic representation of various cancer cells. The large-scale gains, losses and rearrangements of DNA seen in chromosomal instability are a typical feature of cancer — but there is no comprehensive framework to decode the causes of this genomic variability and their possible links to disease. In this week’s issue, Florian Markowetz, Geoff Macintyre and their colleagues present such a framework with a compendium of 17 signatures of chromosomal instability that can be used to predict how tumours might respond to drugs and that help to identify future therapeutic targets. The team created the compendium by examining 7,880 tumours representing 33 types of cancer. In a separate paper, Nischalan Pillay and colleagues examined 9,873 cancers to generate
The promise of a new diet that can add as much as a decade to your life is certainly tempting – and might well be proven to work – but for now should be swallowed with a pinch of salt
