    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...

    Expert eavesdroppers occasionally catch a break

    In July of 1972, NASA launched the first Landsat satellite into orbit around Earth. Since then, the spacecraft and its successors have transformed our understanding of Antarctica (and the rest of the planet, too). In the first year following the launch, Landsat’s images of the faraway continent showed “uncharted mountain ranges, vast ice movements and errors in maps as little as two years old...

    This history book offers excellent images but skimps on modern science

    The Oxford Illustrated History of ScienceIwan Rhys Morus, ed.Oxford Univ., $39.95

    Books about the history of science, like many other histories, must contend with the realization that others have come before. Their tales have already been told. So such a book is worth reading, or buying, only if it offers something more than the same old stories.

    In this case, The Oxford...

    Cows produce powerful HIV antibodies

    An unlikely hero has emerged in the quest to fight HIV: the cow. In a first for any animal, including humans, four cows injected with a type of HIV protein rapidly produced powerful antibodies against the virus, researchers report. Learning how to induce similar antibodies in humans may be key to a successful HIV vaccine.

    The antibodies, called broadly neutralizing antibodies, can stop...

    Climate change could exacerbate economic inequalities in the U.S.

    Climate change may make the rich richer and the poor poorer in the United States.

    Counties in the South face a higher risk of economic downturn due to climate change than their northern counterparts, a new computer simulation predicts. Because southern counties generally host poorer populations, the new findings, reported in the June 30 Science, suggest that climate change will worsen...

    Quantum computers are about to get real

    Although the term “quantum computer” might suggest a miniature, sleek device, the latest incarnations are a far cry from anything available in the Apple Store. In a laboratory just 60 kilometers north of New York City, scientists are running a fledgling quantum computer through its paces — and the whole package looks like something that might be found in a dark corner of a basement. The...
