Studies of past global change from sediments and ice cores have revealed a rich diversity of gradual and rapid perturbations. But more should be done to make the data usable by the research community as a whole.
Huge arrays of detectors now have these ghostly particles in their sights — but will what they see lead physicists to rethink the standard model? Dan Falk investigates.
Undergraduates are not only writing scientific papers — they're reviewing them, editing them and posting them online. Josette Chen examines a scientific publishing phenomenon.
The manufacture of liquid crystal displays still involves a surprisingly low-tech and messy process: rubbing polymer films with a velvet cloth. A twenty-year search for a cleaner alternative may finally be over.
A large-scale study of the protein network in yeast cells demonstrates the merit of taking an integrated approach to cellular dynamics, and shows the value of databases.
Theory suggests that neutron stars should be born rotating rapidly, but in reality they spin more slowly. New calculations suggest that they may be slowed by the emission of exotic gravity waves.
One way of ensuring that a protein is produced in the correct part of the cell is through the distribution of its encoding RNA. It seems that to get RNAs to the apical side of cells, a transport process involving microtubule-based tracks is needed.
The offspring of a mating between two different species are often infertile, or almost so. But it seems that some birds can avoid this apparent cost of hybridization.
A protein that controls the growth and survival of neurons is now shown to have another task: boosting the expression of a molecule that allows neurons to respond to the neurotransmitter dopamine.
Each continent contains pockets of ancient crust that appear to have been unaffected by tectonic forces since they formed billions of years ago. Why? There's now a fresh twist on the usual explanation.
Intuition tells us that a wire without defects should have zero resistance. But in the real world all conductors, however perfect, have some resistance. A new study confirms that electrical contacts are the problem.
Ancient scrolls that have been carbonized cannot easily be unrolled. But their secrets may be revealed by modern means: nuclear magnetic resonance machines should be able to detect any contrast between ink and scroll.
