Unfounded public fears place pressures on vaccine developers that go beyond reasonable safety considerations, as the search for an acceptable vaccine against Lyme disease may demonstrate.
Editors don't expect peer review to catch deliberate fakers. But recent scandals mean that journals are looking at other ways to detect fabricated papers. Emma Marris investigates.
The first vaccine against Lyme disease was withdrawn because patients distrusted it. Should market forces be allowed to shape the next one, asks Alison Abbott.
Two decades after plans were set in motion for the world's most powerful ground-based telescope, astronomers are bracing themselves for a downgrade to curb escalating costs. Jeff Kanipe reports.
A horrible facial cancer is decimating the Tasmanian devil population. But researchers in Australia think they have found a way to save the species. Carina Dennis reports.
When James Watson and Francis Crick unveiled their structure of DNA, one of the two kinds of base pair in the molecule was given two hydrogen bonds instead of three. Who spotted the third bond and when?
Further observations of an object dubbed 2003 UB313, which lies beyond Neptune, show that its diameter is around 3,100 kilometres. This makes it larger than Pluto, the smallest ‘traditional’ Solar System planet.
DNA is duplicated within a complex macromolecular machine. Insights into how replication begins and how this is coordinated with progression of DNA synthesis come from a diverse range of sources.
Self-organization of soft-matter components can create complex and beautiful structures. But the intricate structures created by adding a second stage of organization could reveal more than just a pretty face.
Despite its tiny size, the fruitfly brain is staggeringly intricate. So teasing apart how it remembers things — even a simple line pattern — is a daunting task. Progress is being made, thanks to genetic innovations.
Designing efficient solid-state catalysts would be easier if we knew which parts of them do what. Fluorescence microscopy could help: the technique allows single catalytic events to be observed in real time.
