    Radioactive material from Fukushima disaster turns up in a surprising place

    Six years after the Fukushima nuclear reactor disaster in Japan, radioactive material is leaching into the Pacific Ocean from an unexpected place. Some of the highest levels of radioactive cesium-137, a major by-product of nuclear power generation, are now found in the somewhat salty groundwater beneath sand beaches tens of kilometers away, a new study shows.

    Scientists tested for...

    What Curiosity has yet to tell us about Mars

    View the video

    After five years on Mars, the Curiosity rover is an old pro at doing science on the Red Planet. Since sticking its landing on August 5, 2012, NASA’s Little Robot That Could has learned a lot about its environs.

    Its charge was simple: Look for signs that Gale crater, a huge impact basin with a mountain at its center, might once have been habitable (for microbes, not...

    Borrowed genes give mums the blues

    Mums are now a flower of a different color. Japanese researchers have added a hint of clear sky to the humble plant’s palette, genetically engineering the first-ever “true blue” chrysanthemum.

    “Obtaining blue-colored flowers is the Holy Grail for plant breeders,” says Mark Bridgen, a plant breeder at Cornell University. The results are “very exciting.”

    Compounds called delphinidin-...

    Perovskites power up the solar industry

    Tsutomu Miyasaka was on a mission to build a better solar cell. It was the early 2000s, and the Japanese scientist wanted to replace the delicate molecules that he was using to capture sunlight with a sturdier, more effective option.

    So when a student told him about an unfamiliar material with unusual properties, Miyasaka had to try it. The material was “very strange,” he says, but he...

    Radioactive substances leave electron ‘fingerprints’ behind

    Walls can’t talk, but scientists can now read stories written in their subatomic particles. And that could make it harder to store radioactive material in secret.

    Nuclear radiation rearranges the electrons in insulators such as brick, glass and porcelain. So comparing the positions of electrons in atoms at different spots on walls, windows and floors could provide a rough snapshot of...

    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...

    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...

    Chemistry controlled on tiniest scale can create hollow nanoparticles

    Blame oxidation for rusted bridges and browned avocados. But this fundamental process can be harnessed for good, too — and now scientists have scored front-row seats that could show them how.

    Researchers watched at near-atomic resolution as iron nanoparticles transformed into iron oxide — not rust in this case, but related compounds. That closeup view could help scientists better control...

    How a mushroom gets its glow

    The enzyme that turns on the light for a glow-in-the-dark mushroom seems “promiscuous,” researchers say. But in a good way.

    Researchers from Brazil, Russia and Japan have worked out new details of how two Neonothopanus fungi shine softly green at night. The team had earlier figured out that the basic starting material for bioluminescence in these fungi is a compound called hispidin,...
