The latest twist in Britain's ongoing scare about the safety of a widely used vaccine has brought researchers' conflicts of interest to public attention. Unfortunately, the affair has promoted a simplistic view of this complex issue.
Mount Fuji is a cultural icon and Japan's most important geological feature. Yet until it began rumbling a few years ago, scientists had almost completely ignored it, says David Cyranoski. Is it preparing to erupt again?
Thanks to a sugar found in yeast, it may be possible to provide ‘freeze-dried’ blood cells to treat injured soldiers. The technique could also find applications in the cell-biology lab. Geoff Brumfiel reports.
A challenging way to characterize the world's naturally occurring microbes is to piece together whole genomes from complex communities. An unusually acidic microbial habitat provides the setting for a ranging shot on that target.
A more elaborate picture is developing of what makes some materials superconduct at relatively high temperatures. With it come hints for how to design materials with still higher transition temperatures.
Specialized cells that form barriers such as those of the intestine adopt a distinct asymmetry. One particular protein may be a prime mover in bringing about such cellular organization.
An enzyme involved at grass-roots level in assembling genes for receptors that are essential in fighting infection has now been fingered as a suspect in certain cancers — proof that mistakes can be costly.
The quirky relationship between seawater temperature and density is invoked to account for how, during past global cooling, the high-latitude oceans locked up atmospheric CO2 and produced further cooling.
Accurately distributing half of each replicated chromosome to both daughters is a major challenge for dividing cells. The mechanisms used to achieve this are becoming apparent, thanks to studies old and new.
Graduate-student pay levels mean tight budgets and inventive cost-cutting, but is the five-year pay freeze worth it? Kendall Powell calculates the bottom line.
