    Watch the March for Science in Washington, D.C.

    Science News will be on the scene at the April 22 March for Science in Washington, D.C.  Follow us on Twitter (@ScienceNews) and watch the live stream below.  

    The march may be “unprecedented,” sociologist Kelly Moore told Rachel Ehrenberg for a blog post giving a historical perspective on scientists' activism. “This is the first time in American history where scientists have taken to...

    Ötzi the Iceman froze to death

    NEW ORLEANS — Ever since Ötzi’s mummified body was found in the Italian Alps in 1991, researchers have been trying to pin down how the 5,300-year-old Tyrolean Iceman died. It now looks like this Copper Age hunter-gatherer simply froze to death, perhaps after suffering minor blood loss from an arrow wound to his left shoulder, anthropologist Frank Rühli of the University of Zurich reported...

    Top 10 science anniversaries of 2017

    Second of two parts

    Every year science offers a diverse menu of anniversaries to celebrate. Births (or deaths) of famous scientists, landmark discoveries or scientific papers — significant events of all sorts qualify for celebratory consideration, as long as the number of years gone by is some worthy number, like 25, 50, 75 or 100. Or simple multiples thereof with polysyllabic names....

    In ‘grand finale,’ Cassini spacecraft sets off on collision course with Saturn

    View the animation

    Cassini is bravely going where no spacecraft has gone before — between Saturn and its rings.

    The probe, which launched in 1997 and has orbited Saturn since 2004, starts this daring expedition April 22. It will fly through the 2,400-kilometer-wide gap between Saturn and its rings 22 times before plunging into the planet’s atmosphere and burning up on Sept. 15....

    Collider data hint at unexpected new subatomic particles

    A handful of measurements of decaying particles has seemed slightly off-kilter for years, intriguing physicists. Now a new decay measurement at the Large Hadron Collider in Geneva has amplified that interest into tentative enthusiasm, with theoretical physicists proposing that weird new particles could explain the results. Scientists with the LHCb experiment reported the new result on April 18...

    Immune cells play surprising role in steady heartbeat

    Immune system cells may help your heart keep the beat. These cells, called macrophages, usually protect the body from invading pathogens. But a new study published April 20 in Cell shows that in mice, the immune cells help electricity flow between muscle cells to keep the organ pumping.

    Macrophages squeeze in between heart muscle cells, called cardiomyocytes. These muscle cells...

    50 years ago, continental drift began to gain acceptance

    Drifting theories shake up geology

    Continental drift, a theory often considered amusing but rarely important, seems about to become the focus of a revolution in geology. At the least, it has already split the geological community into those who find the evidence for it “formidable” and those who think it is not yet formidable enough to constitute a proof. — Science News, April 29, 1967...

    Plot twist in methane mystery blames chemistry, not emissions, for recent rise

    A recent upsurge in planet-warming methane may not be caused by increasing emissions, as previously thought, but by methane lingering longer in the atmosphere.

    That’s the conclusion of two independent studies that indirectly tracked concentrations of hydroxyl, a highly reactive chemical that rips methane molecules apart. Hydroxyl levels in the atmosphere decreased roughly 7 or 8 percent...

    Evidence is lacking that ‘cocooning’ prevents whooping cough in newborns

    Last week, I wrote about how powerfully protective whooping cough vaccines can be when babies receive their first dose before even being born, from their pregnant mothers-to-be. As I was looking through that study, another of its findings struck me: Babies didn’t seem to get any extra whooping cough protection when their moms were vaccinated after giving birth.

    I wondered if this meant...
