    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...

    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...

    New heart attack treatment uses photosynthetic bacteria to make oxygen

    Acting like miniature trees that soak up sunlight and release oxygen, photosynthetic bacteria injected into the heart may lighten the damage from heart attacks, a new study in rats suggests.

    When researchers injected the bacteria into rats’ hearts, the microbes restored oxygen to heart tissue after blood supply was cut off as in a heart attack, researchers at Stanford University report...

    The opioid epidemic spurs a search for new, safer painkillers

    Last year, Joan Peay slipped on her garage steps and smashed her knee on the welcome mat. Peay, 77, is no stranger to pain. The Tennessee retiree has had 17 surgeries in the last 35 years — knee replacements, hip replacements, back surgery. She even survived a 2012 fungal meningitis outbreak that sickened her and hundreds of others, and killed 64. This knee injury, though, “hurt like the...

    Global access to quality health care has improved in the last two decades

    Health care quality and availability improved globally from 1990 to 2015, but the gap between the haves and the have-nots widened in those 25 years, researchers report online May 18 in the Lancet.

    As an approximate measure of citizens’ access to quality health care, an international team of researchers analyzed mortality rates for 32 diseases and injuries that are typically not fatal...

    ‘Specimens’ goes behind the scenes of Chicago’s Field Museum

    Most visitors to a large natural history museum don’t know it, but they are only scratching the surface of the museum’s holdings, even if they check out every exhibition. Most of the scientific treasures are tucked away in collection rooms filled with millions of specimens, which scientists use in their research.

    The Field Museum in Chicago, home to Sue, the famous T. rex, is displaying...

    Supermassive black hole gets kicked to the galactic curb

    A black hole weighing more than a billion suns appears to have gotten the boot toward the outer edges of its galaxy.

    Data from the Hubble Space Telescope and other observatories reveal a supermassive black hole zipping away from the center of its galaxy at a 7.5-million-kilometer-per-hour clip. It’s moving so quickly that it could leave the galaxy for good in 20 million years, says Marco...

    Smartphones may be changing the way we think

    Not too long ago, the internet was stationary. Most often, we’d browse the Web from a desktop computer in our living room or office. If we were feeling really adventurous, maybe we’d cart our laptop to a coffee shop. Looking back, those days seem quaint.

    Today, the internet moves through our lives with us. We hunt Pokémon as we shuffle down the sidewalk. We text at red lights. We tweet...
