    New results from Philae lander offer first close-up of a comet

    During its brief time awake on comet 67P/Churyumov-Gerasimenko, the Philae lander documented a diverse world. New analyses of lander data reveal the comet as uniform on the inside, but full of variety on the outside. Pebbles, boulders, cliffs and pits blanket the forbidding landscape. Complex organic molecules float above a surface that is as soft as sand in some places and as hard as rock in...

    Robot springs off water

    Watch video

    New robotic insects can hop on water. Researchers from Harvard University and Seoul National University in South Korea studied live water striders, which can skate and leap on water, to design the robots. The bots weigh just 68 milligrams and have bodies that are 2 centimeters long and legs 5 centimeters long.

    Like real water striders, the robots...

    Caterpillar treats and tricks ants by oozing spiked juice

    Beware the caterpillar offering a juicy treat. Sips tweak ant brain chemistry, lulling the insects into neglecting their own colony in favor of hanging around the source of the marvelous droplets.

    Effects on the brain help Narathura japonica caterpillars recruit a corps of ant bodyguards, says chemical ecologist Masaru K. Hojo of Kobe University in Japan. In lab tests, ants...

    Wolves in jackals’ clothing

    Some canids in Africa could bristle at being called jackals. Using DNA evidence, scientists have built a case that African golden jackals deserve a name change.

    Canids known as golden jackals (Canis aureus) roam Eurasia and Africa. The African and Eurasian animals closely resemble each other, but their looks are deceiving. The two are actually separate species, Klaus-Peter...

    New view of mouse brain provides up-close look at nerve cells’ habitat

    View video

    A tiny speck of mouse brain hosts a microscopic wonderland, a new study reveals. By characterizing the dense, complex habitat of brain cells down to nanometers, scientists have uncovered clues about how the brain wires itself. Among the early revelations: Nearby brain cells don’t always form connections.

    Experimental MERS vaccine battles virus in mice and monkeys

    New experimental vaccines use viral DNA and proteins to help animals’ immune systems fight the virus that causes Middle East respiratory syndrome. The vaccines stimulate the production of antibody proteins that latch onto and disable the MERS virus, researchers report July 28 in Nature Communications....
