  • 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

    2017 delivered amazing biology finds from organisms large and small

    2017 revealed some surprising biology of organisms large and small, from quick-dozing elephants to sex-changing lizards and carbon-dumping sea creatures.

    Switch it up

    Toasty temperatures trump genetics when it comes to the sex of a bearded dragon lizard. Now researchers have found how RNA editing helps turn overheated male embryos into females (SN Online: 6/14/17).

    Here’s what you might have missed in space this year

    Missions to Jupiter and Saturn made big headlines this year, offering closeup views of the two gas giants. 2017 had plenty of other updates from exciting missions of years past.

    Juno

    The Juno spacecraft has kept a watchful eye on Jupiter since entering the gas giant’s orbit in 2016. This year, Juno had seven planned science flybys of the planet, giving researchers a first intimate look at...

    These 2017 discoveries could be big news, if they turn out to be true

    Some reports from 2017 hint at potentially big discoveries — if the research holds up to additional scientific scrutiny.

    Under pressure

    Putting the squeeze on hydrogen gas turned it into a long-elusive metal that may superconduct, Harvard University physicists claimed (SN: 2/18/17, p. 14). A diamond vise, supercold temperatures and intense pressure made the element reflective — a key...

    In marine mammals’ battle of the sexes, vaginal folds can make the difference

    The battle of the sexes, at least among certain ocean mammals, may come down to well-placed skin folds, suggests research by Patricia Brennan, an evolutionary biologist at Mount Holyoke College in South Hadley, Mass., and colleagues.

    In some species, enhanced male-female genital fit has evolved over time in ways that make mating easier. This is an example of what scientists call...

    2017 delivered humility, and proved our potential

    The Top 10 science stories of 2017, selected by Science News staff and presented in this year-end issue, have the potential to make you feel small and certainly humble. Our No. 1 story of the year takes place an unfathomably distant 130 million light-years away, where a neutron star smashup produced, by some estimates, 10 Earth masses worth of gold — wow! That’s enough for many...

    Colliding neutron stars, gene editing, human origins and more top stories of 2017

    In science, progress rarely comes in one big shebang. Well, it has now, two years running. The first-ever direct detection of gravitational waves, our top story in 2016, launched a long-dreamed-of kind of astronomy capable of “unlocking otherwise unknowable secrets of the cosmos,” as physics writer Emily Conover puts it. 2017’s key event: a never-before-seen neutron star collision that...

    This year’s neutron star collision unlocks cosmic mysteries

    Thousands of astronomers and physicists. Hundreds of hours of telescope observations. Dozens of scientific papers. Two dead stars uniting into one.

    In 2017, scientists went all in on a never-before-seen astronomical event of astounding proportions: a head-on collision between two neutron stars, the ultradense remnants of exploded stars.

    The smashup sent shivers of...
