    E-cigarette reports provide science that society craves

    For much of the last year, the most-read story on was not about a faraway exoplanet or a cunning creature’s adaptations to an exotic locale. It was a short report, in some ways unsurprising. In 26 different weeks since it appeared in June 2014, the story at the top of our weekly tab was Janet Raloff’s article on the emerging science about the risks of e-cigarettes. It...

    Puzzling cosmic signals, processed food defined and more reader feedback

    To edit or not

    A controversial paper about modifying genes in fertilized human eggs raised some serious ethical concerns. Tina Hesman Saey covered researchers’ arguments for and against this type of genetic engineering in “Editing human germline cells debated” (SN: 5/30/15, p. 16).

    Many readers embraced the idea of making permanent changes to human DNA. “If someone wants to...

    A loopy look at sunspots

    Tangled nests of magnetic fields burst from sunspots on the solar surface. The spots appear blue and yellow in this false color composite photograph, which was taken in October by NASA’s Solar Dynamics Observatory and released in May. The pale streaks trace magnetic field lines, which stretch up to 200,000 kilometers above the surface (black).

    In visible light, sunspots look like dark...

    In retirement, Nobelist takes up moon bouncing

    If the moon is up, there’s a good chance Joseph Taylor is on his ham radio, using a homemade antenna in his backyard to bounce signals off the moon’s pockmarked face. It’s a skill Taylor began cultivating in 2003, shortly before he retired from Princeton University, where he used radio waves to probe the secrets of pulsars, the spinning, magnetized neutron stars that emit bursts of radiation...

    Quantum dots get a second chance to shine

    Warren Chan helped invent a research field and then watched it nearly die.

    The chemist and biomedical engineer at the University of Toronto specializes in quantum dots, tiny semiconductor particles that glow in a rainbow of colors when zapped with a laser. Fifteen years ago, quantum dots were all the rage. Scientists dreamed of the wild things they could do with them (SN: 6/3/06, p. 344...

    Coyne, a veteran of battles with creationists, says science generates evidence-based knowledge while...

    Alison Jolly’s last book chronicles efforts to save lemurs

    Thank You, MadagascarAlison JollyZed Books, $27.95

    When Alison Jolly died last year, the world lost one of its leading authorities on lemurs. Jolly began studying these primates on her first trip to Madagascar in 1962 and spent much of her career documenting the animals’ social lives. But her academic work was hardly her only legacy. Like many other researchers who study endangered...
