African nations will be more likely to support development projects whose outcomes are indispensable to them. Participants at next week's G8 summit should focus aid in this direction.
The economic miracle that is transforming the world's most populous nation is threatened by energy shortages and rising pollution. It also risks plunging the planet's climate into chaos. Peter Aldhous reports.
Experts in neuroscience, computing and education are coming together in a massive effort to put the way in which children are taught on a sounder scientific footing. Trisha Gura profiles this ambitious — some might say foolhardy — initiative.
Cell doctrine: modern biology and medicine see the cell as the fundamental building block of living organisms, but this concept breaks down at different perspectives and scales.
In an ant species — or is it two species? — females are produced only by females and males only by males. Explanations of this revelation have to invoke some decidedly offbeat patterns of natural selection.
When a drop of liquid plummets onto a surface, the result is a splash — but not it seems if the process occurs at reduced atmospheric pressure. Here, perhaps, is a way to tune splash behaviour for practical ends.
Are current cancer drugs targeted at the wrong kinds of cells? A pioneering approach to the development of treatments uses a mathematical model to follow how different types of tumour cells respond to therapy.
Conventional wisdom says that changes to crustal rocks pushed down deep when continents collide develop over millions of years. But it seems that some metamorphism may be caused by tectonic events lasting only a decade.
How can cells deform yet maintain optimal function? Probing the similarities in the properties of a cell's network of structural filaments, and those of soft glassy materials, may help in tackling this question.
Over the past 30 years magnetic resonance imaging has been refined into a widely used technique. A method known as magnetic particle imaging has now been devised which offers an inner view from a different angle.
The RNA interference pathway can inhibit the expression of specific genes. It now seems that an essential component of the silencing process is the gene-expression machinery itself.
Scientists seeking immunology posts are looking beyond the United States and scattering all over the globe. They are re-evaluating both the focus of their work and where they choose to pursue it, says Myrna Watanabe.
