    New physics books don’t censor the math behind reality

    Many books about science are meant to be pleasure reading. Such books attempt to convey the wonder and fascination and excitement of science, and ideally some of the substance as well. After all, good popular science writing is not only engaging and entertaining, but also informative. But even very informative popular books are not designed to be fully educational about the science in...

    Surgeon aims to diagnose deformities of extinct saber-toothed cats

    Robert Klapper has examined scores of damaged and diseased human knees, hips and shoulders. But a visit to the La Brea Tar Pits and Museum introduced the orthopedic surgeon to the suffering of an extinct cat — and a scientific mystery. In 2000, Klapper took a break from his patients at Cedars-Sinai Medical Center in Los Angeles to visit the nearby tar pits, where myriad mammals and other...

    An American astronomical evangelist coined the phrase ‘island universe’

    No other science engages human curiosity like astronomy. From antiquity onward, attempts to comprehend the architecture of the cosmos have commanded a substantial fraction of humankind’s mental budget for intellectual endeavor. Only in the last century, though, have astronomers grasped the structure of the cosmos accurately. Just a hundred years ago, a great debate raged about the fuzzy...

    The rise of respectful robots

    View the video

    A new robot has the mobility of R2-D2 and the manners of C-3PO.

    This knee-high, self-driving bot abides by social protocols as it weaves through foot traffic: keep right, pass left, respect others’ personal space. The machine, presented at the IEEE/RSJ International Conference on Intelligent Robots and Systems in Vancouver on September 25, paves the way for robots...

  • 50 years ago, a spacecraft discovered oxygen in moon rocks

    The earthy moon

    Space scientists have been intrigued for years with the possibility of finding usable oxygen on the moon — not in the lunar atmosphere, since there essentially is none, but in the rocks. As long ago as 1962 … [NASA researchers] predicted vast lunar processing plants turning out 4,000 pounds of liquid oxygen per month, both for breathing and as an oxidizer for rocket fuel...

    The SN 10: Meet the scientists ready to transform their fields

    Earlier this year, General Electric asked a brilliant question: What if scientist Mildred Dresselhaus was treated like a celebrity? The idea, aired as a TV commercial, had many of us smiling at the possibility. In the ad, fans stop the nanoscience pioneer in the street to take selfies, a young girl receives a Dresselhaus doll as a birthday gift and a student sends a Millie emoji after acing a...

    José Dinneny rethinks how plants hunt for water

    José Dinneny, 39Plant stress biologistCarnegie Institution for Science 

    José Dinneny wants us to see plants as stranger things.

    “They’re able to integrate information and make coherent decisions without a nervous system, without a brain,” he points out. Plus, plants find water without sight or touch. For too many of us, however, lawns, salads and pots on a sunny windowsill make plants so...

    Jennifer Dionne harnesses light to illuminate nano landscapes

    Jennifer Dionne, 35Materials scientistStanford University

    To choose her research goals, Jennifer Dionne envisions conversations with hypothetical grandchildren, 50 years down the line. What would she want to tell them she had accomplished? Then, to chart a path to that future, “I work backward to figure out what are the milestones en route,” she says.

    That long-term vision has led the 35-...

    M. Ehsan Hoque develops digital helpers that teach social skills

    M. Ehsan Hoque, 35Computer scientistUniversity of Rochester

    A growing band of digital characters that converse, read faces and track body language is helping humans to communicate better with one another. While virtual helpers that perform practical tasks, such as dealing with customer service issues, are becoming ubiquitous, computer scientist M. Ehsan Hoque is at the forefront of a more...
