The scientific community had low expectations for the Bush administration when it was first elected. The record since 2001 shows that these expectations were justified.
There's a big difference between a flat layer of cells and a complex, three-dimensional tissue. But until recently, many biologists have glossed over this fact. Alison Abbott discovers what they've been missing.
Want to know what's going on inside your lungs? Conventional imaging techniques are not much use, but by inhaling a magnetized gas you could get a clear picture of your airways. Erica Klarreich investigates.
An obscure marine worm does not belong among the molluscs, as had been thought. Rather, it has a claim to being the most primitive extant member of the group of animals that includes vertebrates.
The connection between random grain motion and viscosity in shaken sand — a strongly non-equilibrium system — has been probed. Curiously, the link is similar to that found in an ordinary liquid in thermal equilibrium.
Artemisinins have been used since ancient times to treat malaria. A new theory could explain how this age-old medicine is able to cause the death of the malaria parasite.
New work shows that a cage-like matrix of protein fibres around cells can inhibit the growth of tumours. But cancer cells producing the enzyme MT1-MMP can cleave this matrix and proliferate freely.
You would have thought that massive monuments would be built by states at the apogee of their pomp and glory. Not so, according to an argument in which it is states on the up that need to impress.
The documentation and characterization of remotely triggered earthquakes deep within the Earth is an achievement that provides insight into the mechanisms that initiate such events.
Two studies of fruitflies suggest that although development relies on a diverse toolkit of genes, the evolution of physical characteristics might be powered by variation in just a few of these tools.
The best way to stack oranges has been evident in markets around the world for centuries, but the mathematics of the problem is far from trivial. The solution for the 24-dimensional case is now within reach.
A protein that controls cell death has been found in a complex with a protein involved in glucose metabolism. Is this a point of contact between these two crucial cellular processes?
