    Mini ‘solar panels’ help yeast shine at churning out drug ingredients

    Bionic microbes outfitted with tiny semiconductor components can generate useful chemicals more efficiently than normal cells.

    Microorganisms like fungi are commonly used in biomanufacturing to convert simple carbon-based molecules, such as sugar, into a wide range of chemical ingredients for pharmaceuticals and other products. But much of a microbe’s carbon intake typically gets used to...

    U.S. cases of a polio-like illness rise, but there are few clues to its cause

    The cause of a rare polio-like disease continues to elude public health officials even as the number of U.S. cases grows.

    Confirmed cases of acute flaccid myelitis cases have risen to 90 in 27 states, out of a possible 252 under investigation, the U.S. Centers for Disease Control and Prevention announced November 13. That’s up from 62 confirmed cases out of 127 suspected just a month ago...

    How mammoths competed with other animals and lost

    The Gray Fossil Site, a sinkhole in northeastern Tennessee, is full of prehistoric treasures. Between 7 million and 4.5 million years ago, rhinoceroses, saber-toothed cats and other creatures, even red pandas, perished here by the edge of a pond. But that bounty of fossils pales next to the site’s biggest find: a mastodon’s skeleton, nearly 5 million years old, preserved in exquisite detail...

    Climate change may have made the Arctic deadlier for baby shorebirds

    Climate change may be flipping good Arctic neighborhoods into killing fields for baby birds.

    Every year, shorebirds migrate thousands of kilometers from their southern winter refuges to reach Arctic breeding grounds. But what was once a safer region for birds that nest on the ground now has higher risks from predators than nesting in the tropics, says Vojtěch Kubelka, an evolutionary...

    One of Earth’s shimmering dust clouds has been spotted at last

    Meet the Kordylewski dust clouds, shimmering pseudo-satellites that orbit Earth near the moon. A team of Hungarian astronomers say they have spotted light scattered from one of these clouds, providing evidence that the clouds really exist after nearly 60 years of controversy.

    The twin dust clouds gather at two of the points in space where the gravity of Earth and the moon cancel each...

    Physicists wrangled electrons into a quantum fractal

    Physicists have created an oddity known as a quantum fractal, a structure that could reveal new and strange types of electron behaviors.

    Fractals are patterns that repeat themselves on different length scales:  Zoom in and the structure looks the same as it does from afar. They’re common in the natural world. For instance, a cauliflower stalk looks like a miniature version of the full...

    China is about to visit uncharted territory on the moon

    China is about to make space history. In December, the country will launch the first spacecraft ever to land on the farside of the moon. Another craft, slated for takeoff in 2019, will be the first to bring lunar rocks back to Earth since 1976.

    These two missions — the latest in China’s lunar exploration series named after the Chinese moon goddess, Chang’e — are at the forefront of...

    A potent fish oil drug may protect high-risk patients against heart attacks

    Cholesterol-lowering drugs may one day gain a sidekick in the battle against heart disease. Taking a potent drug derived from fish oil along with a statin lowers the risk of heart attack and stroke in some high-risk people, researchers report.

    A clinical trial called REDUCE-IT tested the approach in more than 8,000 participants who either had cardiovascular disease or were at high risk...

    Vitamin D supplements don’t prevent heart disease or cancer

    CHICAGO — Taking a vitamin D supplement does not reduce the risk of having a potentially fatal heart attack or stroke or for getting an invasive cancer, according to highly anticipated results of a large clinical trial.

    The VITAL trial found no significant difference in cancer or heart health risk between people taking 2,000 international units, or IU, of vitamin D a day and those who...

    Hints of Oort clouds around other stars may lurk in the universe’s first light

    A thick sphere of icy debris known as the Oort cloud shrouds the solar system. Other star systems may harbor similar icy reservoirs, and those clouds may be visible in the universe’s oldest light, researchers report.

    Astronomer Eric Baxter of the University of Pennsylvania and colleagues looked for evidence of such exo-Oort clouds in maps of the cosmic microwave background, the cool...
