    How oral vaccines could save Ethiopian wolves from extinction

    Deep in the Bale Mountains of Ethiopia, wildlife workers trek up above 9,800 feet to save some of the world’s most rare carnivores, Ethiopian wolves.

    “It’s cold, tough work,” says Eric Bedin, who leads the field monitoring team in its uphill battle.

    In this sparse, sometimes snowy landscape, the lanky and ginger-colored wolves (Canis simensis) reign as the region’s apex predators....

    Meet the giants among viruses

    For decades, the name “virus” meant small and simple. Not anymore. Meet the giants.

    Today, scientists are finding ever bigger viruses that pack impressive amounts of genetic material. The era of the giant virus began in 2003 with the discovery of the first Mimivirus (SN: 5/23/09, p. 9). The viral titan is about 750 nanometers across with a genetic pantry boasting around 1.2 million base...

    Brain waves may focus attention and keep information flowing

    We can’t see it, but brains hum with electrical activity. Brain waves created by the coordinated firing of huge collections of nerve cells pinball around the brain. The waves can ricochet from the front of the brain to the back, or from deep structures all the way to the scalp and then back again.

    Called neuronal oscillations, these signals are known to accompany certain mental states....

    Give double-layer graphene a twist and it superconducts

    LOS ANGELES — Give a graphene layer cake a twist and it superconducts — electrons flow freely through it without resistance. Made up of two layers of graphene, a form of carbon arranged in single-atom-thick sheets, the structure’s weird behavior suggests it may provide a fruitful playground for testing how certain unusual types of superconductors work, physicist Pablo Jarillo-Herrero of MIT...

    On Twitter, the lure of fake news is stronger than the truth

    There’s been a lot of talk about fake news running rampant online, but now there’s data to back up the discussion.

    An analysis of more than 4.5 million tweets and retweets posted from 2006 to 2017 indicates that inaccurate news stories spread faster and further on the social media platform than true stories. The research also suggests that people play a bigger role in sharing falsehoods...
