A WHO report delivers a powerful combination of analysis and economic judgement to suggest that developed countries have much to gain by significantly boosting their efforts to alleviate health problems in the developing world.
Disabling a gene in one mouse strain can be fatal — but in another strain it can produce animals that seem normal. Making sense of such results requires stamina and skill, says Helen Pearson.
Some physicists claim their modelling and data-analysis techniques can change the way we view stock markets. But mainstream economists have yet to be convinced, explains Mark Buchanan.
Ultracold atoms held in a three-dimensional pattern by a web of light beams can now be switched from a superfluid to an insulating state. This achievement may be useful for performing quantum computations.
The p53 protein works to suppress cancer, so one might think that bumping up the levels of this protein would be a good idea. But this isn't so — mice with too much p53 age prematurely.
The usefulness of helium-3 as a probe of the early Universe has been in doubt. A rethink of stellar theory and new observational data put those doubts to rest.
The auditory system transforms information from one frame of reference into another to create a map of space in the brain. The source of a visual signal that guides this transformation in barn owls has now been found.
The origin of magnetic fields found in galaxies and galaxy clusters is unknown. Both models and observations suggest that extinct radio galaxies could be responsible.
It is increasingly evident that bacterial cells cooperate for many purposes. New results show that the bacterium Enterococcus uses cell–cell signalling to coordinate toxin production.
The processes that lead to charge separation in the atmosphere during a thunderstorm are largely mysterious. So Daedalus wants to build a large-scale lightning machine to test the most popular theories.
