    Pregnant male pipefish not so great at giving embryos oxygen

    When a pipefish dad gets pregnant, his brood pouch delivers a surprisingly meager amount of oxygen to the embryos developing inside.

    Broad-nosed pipefish (Syngnathus typhle) swimming in 100 percent oxygenated water in lab tanks delivered on average only about 50 percent of the oxygen to embryos in their brood pouches, says Inês Braga Gonçalves of the University of Zurich. Males...

    African herbivores share space but not diet

    There’s a good reason why so many people want to go on an African safari — savannas in Kenya and other countries are home to plenty of large, photogenic animals, including elephants, giraffes and lions. Who wouldn’t want to see those creatures up close?

    But there’s something a bit quirky about those savannas. They can be home to 10 or even 25 different species of herbivores that all seem...

    An antidepressant may protect against Ebola

    The fearsome Ebola virus may itself fall victim to two already approved medications — the antidepressant drug Zoloft and a drug for patients with heart problems.

    Researchers tested roughly 2,600 compounds and found 30 approved drugs with some capacity to fight the virus in lab-dish tests. The team tested several of these drugs in mice and found that Zoloft, also called sertraline,and the...

    Pluto’s four littlest moons probably born in a crash

    Of Pluto’s five satellites, four — Styx, Nix, Kerberos and Hydra — are packed together about as tightly as possible, researchers report in the June 4 Nature. The four orbits, plus that of the largest moon, Charon, are nearly synced, which suggests that the family formed from debris left behind after something big slammed...

    Neandertal bling and more reader feedback

    Strung out

    Neandertals knew how to accessorize. Eight 130,000-year-old eagle talons unearthed in Croatia show signs of being strung together and worn as a necklace or bracelet, as Bruce Bower reported in “Cache of eagle claws...

    Quantum meets chemistry, opening galaxy of possibility

    As any physicist will tell you, chemistry is really all about physics. But while physical understanding of atoms and their quantum nature has progressed by leaps and bounds in the last century, not all of those insights have produced radical changes in chemistry. A mix of...

    Why breast-feeding really can be easier the second time around

    After my second daughter was born, I was prepared to wait three or four days for my breast milk to come in, as I had with my first. But just as everyone had warned, things were completely different the second time around. Just half a day later, my body was already churning out the good stuff.

    “She’s already got a milk mustache!” one of the nurses told me as she weighed my newborn. That...

    LHC set to see beyond Higgs

    When researchers operating the Large Hadron Collider, or LHC, outside Geneva discovered the Higgs boson, it ended a decades-long effort to fill the final gap in physicists’ catalog of matter’s particles and forces. Now comes the hard part. Physicists know that their catalog is only a start; there’s far more to the universe that needs to be explained. But the LHC’s first round of results...
