    Caesar’s Last BreathSam KeanLittle, Brown and Co., $28

    Julius Caesar could have stayed home on March 15, 44 B.C. But mocking the soothsayer who had predicted his death, the emperor rode in his litter to Rome’s Forum. There he met the iron daggers of 60 senators.

    As he lay in a pool of blood, he may have gasped a final incrimination to his protégé Brutus: You too, my son? Or maybe...

    This glass frog wears its heart for all to see

    A newly discovered glass frog from Ecuador’s Amazon lowlands is giving researchers a window into its heart.

    Hyalinobatrachium yaku has a belly so transparent that the heart, kidneys and urine bladder are clearly visible, an international team of researchers reports May 12 in ZooKeys. Researchers identified H. yaku as a new species using field observations, recordings of its distinct call...

    Bones make hormones that communicate with the brain and other organs

    Long typecast as the strong silent type, bones are speaking up.

    In addition to providing structural support, the skeleton is a versatile conversationalist. Bones make hormones that chat with other organs and tissues, including the brain, kidneys and pancreas, experiments in mice have shown.

    “The bone, which was considered a dead organ, has really become a gland almost,” says Beate...

    See the latest stunning views of Jupiter

    Once every 53 days, Jupiter pulls Juno close. Locked in orbit since July 2016, the spacecraft has made five close flybys of the planet so far. More than 1,300 Earths could fit inside Jupiter, but Juno takes only two hours to zip from pole to pole. That mad, north-to-south trek is shown below in a sequence of 14 enhanced-color images taken May 19.

    Each image’s width corresponds to the...

    In 1967, researchers saw the light in jaundice treatment

    Light helps premature babies

    Premature babies, who often develop jaundice because of an excess of bile pigment called bilirubin, can be saved from this dangerous condition by the use of fluorescent light.… The light alters the chemistry of bilirubin so it can be excreted with the bile. Exchange transfusion is the usual treatment when jaundice occurs but this drastic procedure carries a...

    Life might have a shot on planets orbiting dim red stars

    Our corner of the galaxy teems with alien worlds. In the 25 years since the discovery of the first planets beyond our solar system, astronomers have found more than 3,600 worlds orbiting other stars. A select few have become tantalizing targets in the search for life despite orbiting stars that are much smaller, cooler — and in many ways harsher — than the sun.

    Just 39 light-years away,...

    Top 10 discoveries about waves

    Physics fans are a lot like surfers. Both think waves are really fun.

    For surfers, it’s all about having a good time. For physicists, it’s about understanding some of nature’s most important physical phenomena. Yet another detection of gravitational waves, announced June 1, further reinvigorates the world’s science fans’ excitement over waves.

    Waves have naturally always been a...

    Ancient DNA shakes up the elephant family tree

    Fossil DNA may be rewriting the history of elephant evolution.

    The first genetic analysis of DNA from fossils of straight-tusked elephants reveals that the extinct animals most closely resembled modern African forest elephants. This suggests that straight-tusked elephants were part of the African, not Asian, elephant lineage, scientists report online June 6 in eLife.

    Straight-...

    New dinosaur resurrects a demon from Ghostbusters

    View the video

    Zuul is back. But don’t bother calling the Ghostbusters. Zuul crurivastator is a dino, not a demon. A 75-million-year-old skeleton unearthed in Montana in 2014 reveals a tanklike dinosaur with a spiked club tail and a face that probably looked a lot like its cinematic namesake.

    The find is the most complete fossil of an ankylosaur, a type of armored dinosaur, found...

    Sea scorpions slashed victims with swordlike tails

    Ancient sea scorpions were hacks.

    Some of the marine creatures had a thin, serrated spine on the tip of their tail — and that tail was surprisingly flexible, based on a 430-million-year-old fossil found in Scotland. Slimonia acuminata may have had the range of motion to strike large predators and prey, researchers report online April 18 in American Naturalist.

    Scientists had...
