    Live antibiotics use bacteria to kill bacteria

    The woman in her 70s was in trouble. What started as a broken leg led to an infection in her hip that hung on for two years and several hospital stays. At a Nevada hospital, doctors gave the woman seven different antibiotics, one after the other. The drugs did little to help her. Lab results showed that none of the 14 antibiotics available at the hospital could fight the infection, caused by...

    Antibiotics might fight Alzheimer’s plaques

    A long course of antibiotics reduced the levels of a hallmark of Alzheimer’s disease in the brains of mice, possibly by changing the species of bacteria in the gut. The results, described July 21 in Scientific Reports, suggest that gut bacteria may be linked in some way to Alzheimer’s.

    The finding is preliminary, cautions neurobiologist Robert Moir of Massachusetts General Hospital, but...

    Post-stroke shifts in gut bacteria could cause additional brain injury

    When mice have a stroke, their gut reaction can amp up brain damage.

    A series of new experiments reveals a surprising back-and-forth between the brain and the gut in the aftermath of a stroke. In mice, this dickering includes changes to the gut microbial population that ultimately lead to even more inflammation in the brain.

    There is much work to be done to determine whether the...

    Wiping out gut bacteria impairs brain

    Obliterating bacteria in the gut may hurt the brain, too.

    In mice, a long course of antibiotics that wiped out gut bacteria slowed the birth of new brain cells and impaired memory, scientists write May 19 in Cell Reports. The results reinforce evidence for a powerful connection between bacteria in the gut and the brain (SN: 4/2/16, p. 23).

    After seven weeks of drinking water spiked...

    Science News of the Year 2007

    Tuning In to Science

    In its own way, science is a lot like '60s rock 'n' roll on AM radio. If you're old enough, you remember the slogan: "And the hits just keep on comin'."

    With science, the news just keeps on comin'. Somehow, year after year, science never runs out of hit discoveries. From land-based laboratories to the depths of the oceans to remote realms of the cosmos, intrepid...
