    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...

    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...

    Lena Pernas sees parasitic infection as a kind of Hunger Games

    Lena Pernas, 30ParasitologistUniversity of Padova

    Lena Pernas’ love of parasites began in childhood, when she was plagued with many virtual infections. One of her favorite pastimes as a 9-year-old was playing The Amazon Trail, an educational computer game set near the South American river. One of the dangers players could encounter was malaria, “and I got malaria a lot,” Pernas says. This...

    Christina Warinner uncovers ancient tales in dental plaque

    Christina Warinner, 37Molecular anthropologistUniversity of OklahomaMax Planck Institute for theScience of Human History

    In a pitch-black rainforest with fluttering moths and crawling centipedes, Christina Warinner dug up her first skeleton. Well, technically it was a full skeleton plus two headless ones, all seated and draped in ornate jewelry. To deter looters, she excavated through the night...

    Success in science depends on luck, plus much more

    Like anything else in life, there is a lot of luck in scientific success. Astronomers searching for new worlds have to pick the right sections of sky. Biologists cross their fingers that their cell lines will survive long enough for an experiment. Two paleontologists are excavating at a field site in Montana — both skilled, both committed. One turns up a T. rex skeleton; the other, nothing but...

    Nitty-gritty of Homo naledi’s diet revealed in its teeth

    Give Homo naledi credit for originality. The fossils of this humanlike species previously revealed an unexpectedly peculiar body plan. Now its pockmarked teeth speak to an unusually hard-edged diet.

    H. naledi displays a much higher rate of chipped teeth than other members of the human evolutionary family that once occupied the same region of South Africa, say biological anthropologist...

    Birth control research is moving beyond the pill

    Mention “the pill,” and only one kind of drug comes to mind. The claim that oral contraceptives have on that simple noun testifies to the pill’s singular effect in the United States. Introduced in 1960, the pill gave women reliable access to birth control for the first time. The opportunity to delay having children opened the door to higher education and professional careers for many women....

    To combat cholera in Yemen, one scientist goes back to basics

    Rowa Mohammed Assayaghi teaches people how to wash their hands. In Yemen, that’s life-saving work.

    The Middle Eastern country is facing the world’s largest cholera outbreak, with nearly 409,000 suspected cases and 1,885 deaths from late April to late July, the World Health Organization reports. That tally is higher than 2015’s worldwide reported cholera deaths. A bacterial infection...

    South Asia could face deadly heat and humidity by the end of this century

    India and Pakistan are no strangers to extreme temperatures. In 2015, two heat waves killed more than 3,500 people there. But by the end of the century, new climate simulations suggest, extreme heat and humidity could put hundreds of millions at risk of death.

    Published online August 2 in Science Advances, the simulations show fairly specifically where future heat waves will be most...

    Your solar eclipse experience can help science

    With just weeks to go before the Great American Eclipse, scientists are finalizing years of planning to study the solar phenomenon. But it’s not too late to get involved.

    “This is the first eclipse crossing over a major landmass in the era when lots of people have digital devices,” says astronomer Alex Filippenko of the University of California, Berkeley. The 120-kilometer-wide path of...
