    Readers were curious about green icebergs, aliens and more

    Going green

    Researchers found iron oxides trapped in a sample of green Antarctic ice. The compounds may explain why typically blue-hued icebergs can sometimes appear green, Jeremy Rehm reported in “Tiny bits of iron may explain why some icebergs are green” (SN: 3/30/19, p. 12).

    “Since icebergs can drift for thousands of miles, and because iron is a limiting nutrient for algae, I...

    A gut bacteria transplant may not help you lose weight

    Changing your gut microbes may not help you lose belly fat.

    In a preliminary study, obese people got either capsules containing gut microbes from a lean person or placebo pills. Microbes from the lean donor took hold in the guts of the obese recipients. But early results suggest that the bacteria didn’t change the volunteers’ weight or levels of a hormone that helps signal fullness,...

    A mysterious dementia that mimics Alzheimer’s gets named LATE

    A newly described dementia strikes people in their last decades of life. The disease, aptly named LATE, comes with symptoms that resemble Alzheimer’s disease, but is thought to be caused by something completely different.

    An international team of scientists and clinicians describe the disease and officially christen it LATE, which stands for the more technical description, “limbic-...

    How holes in herd immunity led to a 25-year high in U.S. measles cases

    Measles is so contagious that the virus can unerringly find the unvaccinated. That knack, combined with the number of people in the United States who haven’t been vaccinated against the disease, has given measles an opening that it hasn’t had in the country for decades.

    U.S. measles cases have surged to a 25-year high of 704, the U.S. Centers for Disease Control and Prevention reported...

    U.S. measles cases hit a record high since the disease was eliminated in 2000

    U.S. measles cases have soared to the highest number since the disease was declared eliminated in the country in 2000. The 2019 tally now stands at 695 cases, the U.S. Centers for Disease Control and Prevention reports. That surpasses the previous high of 667 cases in 2014.

    “The high number of cases in 2019 is primarily the result of a few large outbreaks — one in Washington State and...

    A neural implant can translate brain activity into sentences

    To communicate, people unable to talk often rely on small eye movements to spell out words, a painstakingly slow process. Now, using signals picked up by a brain implant, scientists have pulled entire sentences from the brain.

    Some of these reconstructed words, spoken aloud by a virtual vocal cord, are a little garbled. But overall, the sentences are understandable, researchers from the...

    ‘Invisible Women’ spotlights a gaping and dangerous gender data gap

    Invisible WomenCaroline Criado PerezAbrams Press, $27

    The recent cancellation of the first all-female spacewalk occurred after the publication of Caroline Criado Perez’s Invisible Women. But the news — the lack of enough space suits for the women, suits which weren’t designed for the shape of women’s bodies in the first place — would fit right in to Criado Perez’s scathing takedown...

    Dead pig brains bathed in artificial fluid showed signs of cellular life

    Scientists have restored cellular activity to pig brains hours after the animals’ death — an unprecedented feat. This revival, achieved with a sophisticated system of artificial fluid, took place four hours after the pigs’ demise at a slaughterhouse.

    “This is a huge breakthrough,” says ethicist and legal scholar Nita Farahany of Duke University, who wasn’t involved in the research. “It...

    ‘Added sugar’ food labels may prevent heart disease and diabetes

    Nutrition label changes aimed at curbing America’s sweet tooth could have a sizable payoff for public health.

    A new study projects that the updated labels, which detail the amount of sugar added to a food or drink, could help the average U.S. adult cut sugar consumption by around half a teaspoon a day. If that happens, the labeling change could prevent around 350,000 cases of...
