    African farmers’ kids conquer the marshmallow test

    Children of Nso farmers in Cameroon know how to master the marshmallow test, which has tempted away the self-control of Western kids for decades.

    In a direct comparison on this delayed gratification task, Cameroonian youngsters leave middle-class German children in the dust when challenged to resist a reachable treat while waiting for another goodie, a new study finds.

    Of 76 Nso 4-...

    Ancient attack marks show ocean predators got scarier

    In pumped-up sequels for scary beach movies, each predator is bigger than the last. Turns out that predators in real-world oceans may have upsized over time, too.

    Attack holes in nearly 7,000 fossil shells suggest that drilling predators have outpaced their prey in evolving ever larger bodies and weapons, says paleontologist Adiël Klompmaker of the University of California, Berkeley. The...

    In 1967, researchers saw the light in jaundice treatment

    Light helps premature babies

    Premature babies, who often develop jaundice because of an excess of bile pigment called bilirubin, can be saved from this dangerous condition by the use of fluorescent light.… The light alters the chemistry of bilirubin so it can be excreted with the bile. Exchange transfusion is the usual treatment when jaundice occurs but this drastic procedure carries a...

    Life might have a shot on planets orbiting dim red stars

    Our corner of the galaxy teems with alien worlds. In the 25 years since the discovery of the first planets beyond our solar system, astronomers have found more than 3,600 worlds orbiting other stars. A select few have become tantalizing targets in the search for life despite orbiting stars that are much smaller, cooler — and in many ways harsher — than the sun.

    Just 39 light-years away,...

    Ladybugs fold their wings like origami masters

    View the video

    Those who struggle to fit a vacation wardrobe into a carry-on might learn from ladybugs. The flying beetles neatly fold up their wings when they land, stashing the delicate appendages underneath their protective red and black forewings.

    To learn how one species of ladybug (Coccinella septempunctata) achieves such efficient packing, scientists needed to see under the...

    50 years ago, antibiotic resistance alarms went unheeded

    Bacteria ganging up on drugs

    With the discovery of sulfa drugs and antibiotics came man’s confidence in his ability to control infectious diseases. But now, that confidence is being shaken by once defenseless germs that have learned to outwit man and thrive in the face of his wonder drugs.… One way to cut down on drug resistance transfer is to stop prescribing antibiotics almost...

    Mummy DNA unveils the history of ancient Egyptian hookups

    Egyptian mummies are back in style at the summer box office — and in genetics labs. A study of genetic blueprints from 90 mummies repairs the frayed reputation of sarcophagus occupants as sources of ancient DNA. And it reveals evidence of a hookup history with foreigners from the east.

    An Egyptian mummy served up the first ancient human DNA sample in 1985 (SN: 4/27/85, p. 262). But both...

    50 years ago, an Earth-based telescope spotted Saturn’s fourth ring

    Saturn: Four Rings

    Walter A. Feibelman of the University of Pittsburgh … has found evidence indicating a fourth ring [of Saturn].… Every 14.78 years, the rings of Saturn can be seen edge-on from Earth, and the past winter marked one of these opportunities.… The thin ring “extends to more than twice the known ring diameter” (or a total of 340,000 miles), and is so faint it cannot be...

    50 years ago, U.S. fell short on mosquito eradication

    Mosquitoes on the way out

    By 1973, just nine years after the start of an antimosquito campaign, the Aedes aegypti will be eradicated from the United States. The mosquito, a potential carrier of yellow fever, dengue and hemorrhagic fever, has been the target of a $23 million attack launched in 1964…. The carrier of these viral diseases can still be found in 10 southern states, Hawaii, the...

    Yes, statins protect hearts. But critics question their expanding use

    Cholesterol is so important to life that practically every human cell makes it. Cells use the compound to keep their membranes porous and springy, and to produce hormones and other vital substances. The body can make all the cholesterol it needs, but Americans tend to have a surplus, thanks in large part to too little exercise and too much meat, cheese and grease. Fifty years ago, researchers...
