    Pollution is endangering the future of astronomy

    OXON HILL, Md. — Even as technological advances allow astronomers to peer more deeply into the cosmos than ever before, new technologies also have the potential to create blinding pollution.

    Three sources of pollution — space debris, radio interference and light pollution — already are particularly worrisome. And the situation is getting worse. In the next two decades, as many as 20,000...

    OXON HILL, Md. — Ever wonder what it would be like to sit at the center of the Milky Way and watch the galaxy swirl by? A video debuted in a January 10 news conference at the American Astronomical Society Meeting provides a glimpse.

    The 360-degree-simulation, made with data from several telescopes, including NASA's Chandra X-ray Observatory and the European Southern...

    This artificial cartilage gets its strength from the stuff in bulletproof vests

    A new kind of artificial cartilage, made with the same kind of fiber that fortifies bulletproof vests, is proving stronger than others.

    The fabricated material mimics the stiffness, toughness and water content of natural cartilage, researchers report in the Jan. 4 Advanced Materials. This synthetic tissue could replace the cartilage in a person’s body that naturally wears down and heals...

    Hormone replacement makes sense for some menopausal women

    Internist Gail Povar has many female patients making their way through menopause, some having a tougher time than others. Several women with similar stories stand out in her mind. Each came to Povar’s Silver Spring, Md., office within a year or two of stopping her period, complaining of frequent hot flashes and poor sleep at night. “They just felt exhausted all the time,” Povar says. “The joy...

    Website invites you to probe a 3-D human brain

    In movies, exploring the body up close often involves shrinking to microscopic sizes and taking harrowing rides through the blood. Thanks to a new virtual model, you can journey through a three-dimensional brain. No shrink ray required.

    The Society for Neuroscience and other organizations have long sponsored the website BrainFacts.org, which has basic information about how the human...

  • How the Dead Sea Scrolls survived a war in the 1960s

    Dead Sea Scrolls safe

    The famous Dead Sea Scrolls, rumored lost or damaged during the June war between Israel and Egypt, are safe, according to Antiquity…. On the eve of the war they were packed up and put safely in a strong room in the basement of the Palestine Archaeological Museum (Rockefeller Museum), according to a reliable authority. —  Science News, January 20, 1968

    These disease-fighting bacteria produce echoes detectable by ultrasound

    Ultrasound can now track bacteria in the body like sonar detects submarines.

    For the first time, researchers have genetically modified microbes to form gas-filled pouches that scatter sound waves to produce ultrasound signals. When these bacteria are placed inside an animal, an ultrasound detector can pick up those signals and reveal the microbes’ location, much like sonar waves bouncing...

  • 50 years ago, synthetic DNA made its debut

    Viable synthetic DNA

    [Scientists] produced in a test tube a totally artificial copy of a type of DNA virus.… The particular type of viral DNA (called Phi X174) the researchers made is an extremely simple molecule of only five or six genes. Their achievement, however, lays the foundation for eventual synthesis of more complex DNAs. — Science News, December 30, 1967

    Tiny trackers reveal the secret lives of young sea turtles

    View the video

    Not so long ago, the lives of sea turtles were largely a mystery. From the time that hatchlings left the beaches where they were born to waddle into the ocean until females returned to lay their eggs, no one really knew where the turtles went or what they did.

    Then researchers started attaching satellite trackers to young turtles. And that’s when scientists...
