    Mystery still surrounds Neandertals

    Past, Modern Man Linked — Neanderthal man may have built structures, indicating that he was far more advanced than formerly believed and implying that he may have evolved into Cromagnon man. Evidence uncovered at the Molodova site in the Ukraine … is a circle of...

    More mysterious extragalactic signals detected

    Just in time for the holiday shopping season, astronomers snagged a two-for-one deal on mysterious blasts of radio waves from other galaxies. An unprecedented double burst recently showed up along with four more of these flashes, researchers report online November 25 at

    Fast radio bursts, first detected in 2007, are bright blasts...

    For a python, every meal is like Thanksgiving

    For millions of Americans, Thanksgiving is an excuse to gorge on turkey, stuffing and pumpkin pie, despite the warnings that overeating, even for a day, can be incredibly unhealthy. But for a Burmese python,...

    Water bears are genetic mash-ups

    Water bears may be the ultimate borrowers.

    The hardy, microscopic animals also known as moss piglets and technically called tardigrades have scavenged about 17.5 percent of their genes from other creatures. The ability to pick up used genes and spare parts from other organisms’ DNA junkyards may allow tardigrades...

    Taste is all in your head

    View the video

    It’s not water into wine, but close enough. By stimulating certain nerve cells in the brains of mice, scientists made plain water taste sweet or bitter. The results show that the brain — not the tongue — is the ultimate tastemaker...

    Final chapter published in decades-long Gravity Probe B project

    A grueling but ultimately successful effort to test Einstein’s 100-year-old general theory of relativity has come to a close more than half a century after it began. Twenty-one papers published online November 17 in Classical and Quantum Gravity present a detailed summation of Gravity Probe B, a satellite that in 2011...

    Gut microbes signal when dinner is done

    Gut bacteria are not polite dinner guests. They fill up fast and tell their host to quit eating, too.

    After only 20 minutes, helpful E. coli populations that live in animal guts produce proteins that can curb how hungry its animal partner is, researchers show November 24 in Cell Metabolism. In mice and rats, the proteins stimulated brain-body responses that led the...

    Conifer ancestors had a double dose of DNA

    Conifers grew giant genomes thanks to double doses of genetic material.

    Ancient ancestors of today’s pine, cypress and yew trees had extra copies of their entire genome — the set of genetic instructions for an organism, researchers report November 20 in Science Advances.  

    Whole genome duplications are...

    Don’t flip out: Earth’s magnetic poles aren’t about to switch

    Earth is not heading toward a doomsday reversal of its magnetic field, new research assures.

    The planet’s magnetic field is about 10 percent wimpier today than when physicists began keeping tabs on it in the 1800s. In the geologic past, such weakening preceded geomagnetic reversals —swaps of the north and south magnetic poles. Such reversals temporarily make the planet more vulnerable to...

    Mosquitoes engineered to zap ability to carry malaria

    A new genetic engineering technique may quickly inoculate mosquitoes against malaria, helping to end the spread of the disease in humans.

    Using a gene-editing tool known as CRISPR/Cas9, researchers have made a “genetic vaccine” that will continually inject itself into mosquitoes’ DNA. Such a vaccine, known as a gene drive, could spread to nearly every mosquito in a population within a...
