With the use of transgenic crops expanding around the globe, we need to decide what level of unapproved plants we are willing to accept in our diets. Zero is not an option, says Heidi Ledford.
Two years after a radical change that brought India's patent laws into line with international trading rules, the country's drug makers are taking a new direction. Apoorva Mandavilli reports.
Containing a potential HIV explosion in the strife-torn Niger delta is a tough job — but circumstances are forcing the oil and gas industries to confront it. Colin Macilwain reports.
Life is full of events that are basically games, from paying for a meal to bidding in an auction. Can incorporating a quantum strategy into the rule book increase your chances of winning? Navroz Patel reports.
The oldest known animal fossils, identified as eggs and embryos, had been expected to reveal secrets from a period of great evolutionary change. Will the latest theory about the fossils' origins confound these hopes?
Our description of how the atomic nucleus holds together has up to now been entirely empirical. Arduous calculations starting from the theory of the strong nuclear force provide a new way into matter's hard core.
A population-genetic model indicates that if there is a gene responsible for homosexual behaviour it can readily spread in populations. The model also predicts widespread bisexuality in humans.
Some of our suppositions about the marine nitrogen cycle may be wrong. An innovative analysis of nutrients at the ocean's surface reveals a feedback mechanism that might hold the whole cycle in balance.
The project for producing a genome-wide atlas of gene expression in the mouse brain shows how, with advancing technology, huge volumes of data can be collected and made accessible through the Internet.
The mineral zircon suffers more structural damage from the α-decay of plutonium present in its crystal than was thought. That could have a knock-on effect on strategies for managing nuclear waste.
A new approach to determine nitrogen fixation rates in the world's oceans is used; it involves interpreting nutrient distributions in the context of an ocean circulation model.
The expression of each of the roughly 22,000 genes of the mouse genome has been mapped, at cellular resolution, across all major structures of the mouse brain, revealing that 80% of all genes appear to be expressed in the brain.
Inelastic magnetic neutron scattering measurements point to the distinct possibility that genuine long-range antiferromagnetism and superconductivity do not coexist.
A coupled chemical–physical model of conduit flow shows that the oxidation state of an ascending magma is strongly dependent on both the composition and amount of gas in the reservoir.
This study provides a replicated, quantitative demonstration of the consequences of human-mediated habitat modification for networks of feeding interactions among species in tropical host–parasitoid food webs.
Bacterial proteorhodopsins are light-dependent proton pumps broadly distributed in the ocean environment. Their physiological role has now been elucidated in Flavobacteria, where the harvested light energy can translate into enhanced growth.
