The Federation of American Scientists for Experimental Biology and the Association of American Medical Colleges lead the 'heads-in-the-sand' school on the scientific misconduct issue.
A small but growing group of astronomers wants to put the night sky on the Internet. But will staring at a computer screen ever replace peering through a telescope? Geoff Brumfiel logs on.
If we can understand why a woman's body does not reject her fetus, it could help us to treat infertility and prevent problems in pregnancy. Helen Pearson reports.
No statistical documentation of objects of a certain size that enter Earth's atmosphere has hitherto been available. Analysis of data from US government satellites has bridged the gap.
It is no mean feat for organisms to make and maintain their organs. The complex cellular and molecular processes involved are illustrated by two studies of the proteins that participate in producing a colon.
If laser light is shone on a solution, the crystal structure that forms depends on the light polarization, and the more intense the laser, the greater the probability of crystal nucleation. The challenge now is to work out why this is.
A key question about evolution is how the first informational molecules — thought to be an early form of life — could generate efficient self-replication machinery. The problem is tackled in new computer simulations.
Osmium isotopes record evidence for 2.5-billion-year-old mantle beneath the Azores. The origin of this ancient mantle has implications for the nature and timescale of mantle convection.
The identification of a transport mechanism for boron in plant roots provides a surprising connection with transport systems in other, very different settings, such as the kidney.
