1. Time can move both forwards and backwards at the quantum scale
   Physicists use mathematical assumptions in many situations that forbid time from moving backwards – but that isn’t necessarily a reflection of quantum reality
2. How does astronomy fit into astrophysics – and does it matter?
   We need to think more carefully about how we categorise the universe, says Chanda Prescod-Weinstein
3. Record-breaking neutrino spotted tearing through the Mediterranean Sea
   A neutrino with more energy than we've ever seen before was picked up by a detector on the floor of the Mediterranean Sea, and it seems to have a distant cosmic origin
4. How big is a neutrino? We're finally starting to get an answer
   Our estimates of the size of a neutrino span from smaller than an atomic nucleus to as large as a few metres, but now we are starting to narrow down its true value
5. How cosmic stasis may drastically rewrite the history of the universe
   Unexpected epochs of stillness that punctuate the cosmic timeline could offer a natural explanation for dark matter and many other unsolved astronomical mysteries
6. The perfect boiled egg takes more than half an hour to cook
   If you have the patience to repeatedly switch an egg between a hot and a colder pan, you'll be rewarded with an amazing taste and texture, say physicists
7. The superconductivity of layered graphene is surprisingly strange
   The odd superconductivity found in layered graphene may bring us closer to understanding room-temperature superconductors
8. The 100-year-old symmetry theorem that is still changing physics today
   Emmy Noether was hailed as a mathematical genius in her own time. And her theorem on symmetry is still driving new discoveries in particle physics and quantum computing today
9. Experiment with 37 dimensions shows how strange quantum physics can be
   A search for particles’ most paradoxical quantum states led researchers to construct a 37-dimensional experiment
10. A new kind of hidden black hole may explain the mystery of dark energy
    Space-time may hide a bizarre new kind of black hole that causes Einstein’s theory of gravity to fail – and could solve the mystery of dark energy
