<jats:p> <jats:italic>Science</jats:italic> NOW reported this week that a new sensor can detect the explosive triacetone triperoxide, malaria in India is much worse than feared, exercise boosts muscle stem cells, and new clues to the origins of higher primates have been found, among other stories. </jats:p>

<jats:p> The 1000 Genomes Project has produced a compendium of millions of previously unknown single-nucleotide polymorphisms and other variants, described in work published this week. A second analysis in this week's issue of <jats:italic>Science</jats:italic> describes an approach for determining another aspect of genetic variation that arises when genes and other stretches of DNA are duplicated. </jats:p>

<jats:p>The Pentagon is fuming after last week's release of a huge cache of classified Iraq War data by the organization WikiLeaks. But researchers struggling to build an accurate picture of the death toll in post-invasion Iraq are thrilled.</jats:p>

<jats:p>Armed with nearly $10 million raised by telethons, a research “dream team” hopes to prove that a new approach to cancer therapy can halt solid tumors.</jats:p>

<jats:p>Recent reports that genes affecting chromatin structure are mutated in several types of solid tumors could help resolve the conundrum of whether so-called epigenetic changes are a cause or a consequence of disease.</jats:p>

<jats:p>Genome scans have turned up single nucleotide polymorphisms associated with different responses to treatment, but efforts to uncover the mechanism have drawn a blank.</jats:p>

<jats:p>Most efforts to improve education in science, technology, engineering, and mathematics start with recruitment. But working with those teachers already in the classroom may yield a bigger payoff.</jats:p>

<jats:p>How far would training 10,000 more science, technology, engineering, and math teachers a year for the next 10 years go toward achieving President Barack Obama's goal of making the country No. 1 in math and science education? No one seems to know.</jats:p>

<jats:p>Several speakers at the meeting used paleontological data to predict the future, drawing on species' behavior during past episodes of climate change to predict how they will fare—and how to help them—as greenhouse gases warm the planet.</jats:p>

<jats:p>At the meeting, researchers announced the discovery of some of the world's oldest rodents, an important clue to the mystery of how the first modern mammals spread around the globe, replacing archaic animals and ushering in the age of modern mammals.</jats:p>
