<jats:p>Physicists working with an ultrasensitive particle detector deep underground reported three blips that could be particles of dark matter—suggesting that weakly interacting massive particles might not be far off.</jats:p>

<jats:p>Early next month, scientists will break ground on Sirius, a synchrotron x-ray source whose energy and brightness will rival those of the best machines in the world.</jats:p>

<jats:p>North Korea has one of the highest TB rates outside sub-Saharan Africa and a burgeoning drug-resistance problem. A remarkable unusual collaboration is hoping to turn the tide.</jats:p>

<jats:p>Paleoanthropologists announced a modern feature in a rare, 1.4-million-year-old hand bone from Kenya, filling a 1-million-year gap in the fossil record and showing when key adaptations to toolmaking arose.</jats:p>

<jats:p>A team described 1.5-million-year-old footprints of at least six individuals walking together across the sand at Ileret, Kenya. Coupled with experiments with living people, the researchers concluded that the size and direction of the prints suggest a party of males out hunting or on patrol, an example of male coalitionary behavior also seen in chimpanzees.</jats:p>

<jats:p>Researchers gave Ardi, the oldest and most complete skeleton of a potential human ancestor, new recognition as a hominin.
