    Baby seahorses’ toddler phase

    Newborn seahorses look like their parents. They already have the power for beyond-fast strikes at prey. And their tails end with a miniature up-curl like a grown-up’s prehensile marvel. But they’re babies, and they bumble.

    That’s the impression of evolutionary morphologist Dominique Adriaens, who has watched several Hippocampus species born in his lab at Ghent University in...

    Age affects brain’s response to anesthesia

    Anesthesia elicits different patterns of brain waves in the very young and very old, scientists have found. Understanding these distinctions may ultimately lead to brain monitors that could make surgery safer for these vulnerable patient populations. 

    These findings are groundbreaking, says neuroanesthesiologist Stacie Deiner of Icahn School of Medicine at Mount Sinai in New York City....

    Help ornithologists develop bird photo ID tool

    If you have a terrific picture of a Tennessee warbler, you can help the Cornell Lab of Ornithology improve its Merlin Bird Photo ID program. Upload your picture and put dots on the beak, eye and tail tip. Then, using patterns in the data, Merlin attempts to identify the bird. The aim is to help Cornell create a mobile device tool for...

    Antibody that fights MERS found

    By mining the immune cells of a patient that beat the MERS virus, scientists have identified a protein that could help prevent and treat the deadly disease.

    When tested in mice, the protein targeted the virus that causes Middle East respiratory syndrome. The protein could be used to develop vaccines or treatments to protect people from the MERS virus,...

    Microbes’ role in truffle scents not trifling

    Truffles, the homely fungal celebrities of the culinary world, have unseen help concocting their prized — and pricey — aromas.

    Microbes that inhabit the subterranean mushrooms probably produce key chemicals that make truffles smell like truffles, according to a new analysis appearing online July 17 in Applied and...

    Laser light made inside cells

    Biologists often use lasers to probe cells. Now, for the first time, cells have returned fire.

    Harvard University researchers have created intracellular lasers by implanting microscopic beads and oil droplets into animal cells. When energized by an outside laser pulse, an implant traps and amplifies light and then emits a laser pulse of its own. “It’s a wonderful way of coupling optics...

    Revamping the metric measure of mass

    The metric system is on track for a mass makeover.  

    In an effort to provide accurate measurements at all scales, scientists are preparing to redefine four basic units by the end of 2018. The shift will most notably affect the kilogram, the base measure of mass and the last member of the International System of Units still defined by a physical object. Current efforts are under way to...

    Pluto’s icy landscape comes into view

    LAUREL, Md. — Alan Stern, head of the New Horizons mission to Pluto, had just three words for the team of scientists and engineers assembled with him on July 14: “We did it.”

    At 8:52:37 p.m. Eastern time, a radio antenna near Madrid received the first signal from the spacecraft since it buzzed the dwarf planet. After decades of planning and a 9....
