    To combat an expanding universe, aliens could hoard stars

    Survivalists prep for disaster by stocking up on emergency food rations. Aliens, on the other hand, might hoard stars.

    To offset a future cosmic energy shortage caused by the accelerating expansion of the universe, a super-advanced civilization could pluck stars from other galaxies and bring them home, theoretical astrophysicist Dan Hooper proposes June 13 at arXiv.org.

    The most ancient African baobabs are dying and no one knows why

    The last 13 years have been terrible for ancient African baobab trees.

    Nine of the 13 oldest either lost trunks or died altogether after having lived for longer than a millennium, researchers report June 11 in Nature Plants. But just what the demise means for the iconic species is up for debate.

    Leaf-cutter ants pick up the pace when they sense rain

    In Central America’s rain-drenched forests, leaf-cutting ants collect pieces of leaves on which they grow fungi for food. But the rain can hit hard, especially for a small ant. When leaf-cutting ants sense an incoming shower, they hoof it back to their nests, says a study in the May Insectes Sociaux.

    Researchers from Argentina, Mexico and Peru tested how one species of leaf-cutting ants...

    How birds may have escaped the dino-killing asteroid impact

    Nothing against trees. But maybe it’s better not to get too dependent on them if you want to survive a big flaming space object crashing into Earth.
