How the malaria parasite slips into a blood cell, seen up close
To multiply in the body, the malaria parasite must get inside red blood cells, through a portal that opens and seals behind it in under a minute. What does that doorway look like, and how does it work? Joanna Thompson follows a Columbia University lab that has finally imaged it. Read it for a clear account of a mechanism that escaped microscopes for decades, and why it matters for future drugs. We picked it for explaining biophysics without dumbing it down. Quanta's funder, the Simons Foundation, part-funded the research, as the magazine discloses; we found no stake for Thompson.

Looking for Alzheimer's early warning signs in Brazilians
Original title: Quais são as pistas do Alzheimer antes dos primeiros sintomas?
Alzheimer's changes can build up in the brain for years before memory fails. Can they be spotted early in Brazilians, whose genetics differ from those of most research cohorts, and should volunteers be told? Tiago Jokura reports on a São Paulo study following people with memory complaints, and on why recruiting a representative sample is so hard. Read it for the science and the ethics of knowing too soon. We picked it for showing how medicine depends on who gets studied. Jokura reports for Pesquisa FAPESP, published by the agency that funds the study, a stake for the publisher.

03 ★★★★☆
Biology's boldest theories came before the evidence. How?
Two foundational ideas in biology, how cells make their energy and how the immune system learns to recognise invaders, were proposed before any experiment could show them. Where did such leaps come from? Ulkar Aghayeva retraces the reasoning of Peter Mitchell, Niels Jerne, Macfarlane Burnet and others, and the philosophy behind it. Read it for a rare look at how theories actually get made, rather than how textbooks tidy them up afterwards. We picked it as the most original essay we reviewed. Aghayeva is a science writer and columnist at Asimov Press; we found no stake.

04 ★★★☆☆
The voting paradox that turns out to have a shape
Since Condorcet in the 18th century, we have known that voters with perfectly consistent preferences can together produce a result that runs in circles. Now three mathematicians have given that paradox a geometric form. Alex Stone walks through the topology, from a single ballot to the strange surface that all possible ballots make together. Read it to see why no voting system escapes trade-offs, and what mathematics can and cannot settle about them. We picked it as this issue's wildcard: an old question in political theory, reached through geometry. Stone writes for Quanta; we found no stake.

05 ★★★☆☆
Kashmir's fading springs, and where to look for the cause
Springs supply many Himalayan villages in Kashmir, and residents say some are running weaker each year. Is the cause climate, land use, or something further up the slope? Karen Coates reports from Ganderbal district, setting villagers' memories beside University of Kashmir research on where spring water enters the ground. Read it to understand why a spring cannot be protected at its outlet alone, and why the cause of its decline is so hard to pin down. We picked it for its careful handling of uncertain science from a rarely covered region. Coates reports for Mongabay; we found no stake.

06 ★★★☆☆
Where one bacterial species ends and the next begins
Bacteria swap genes across species lines, so what does naming a microbe mean, and why should regulators care? Kevin Blake traces microbial classification from Linnaeus to genome sequencing, as the tree of life turned tangled. Read it for a lively history of taxonomy that ends on a current policy question: in the United States, whether an engineered microbe faces review can depend on a genus boundary. We picked it for linking old science to today's rules. Blake is a scientific editor in laboratory and genomic medicine at Washington University; the essay argues for risk-based rules, and we found no stake.
