A maverick scientist becomes a guinea pig

 

Spencer Lowell

A variety of creatures across the animal kingdom navigate by sensing Earth’s magnetic field—a talent known as magnetoreception. Joe Kirschvink, a geophysicist at the California Institute of Technology in Pasadena, is trying to figure out whether humans can do the same. Here he is, about to be exposed to custom magnetic fields generated by an array of electrical coils, while an electroencephalogram machine records his brain waves.

An adorable assassin

This cute little Solenodon is a close cousin of the “island murderer,” otherwise known as the genus Nesophontes, which were prolific killers of insects across the Caribbean. Scientists are using fossilized DNA to trace the history of Nesophontes, 5 centuries after they went extinct.

Ear in a dish

A new ear may be just a 3D printer away. That’s the promise of the integrated tissue-organ printer, which laces artificial body parts with living cells to produce specimens like this one.

Namibian clouds could help solve global warming puzzle

The coastal fog above provides a beguiling backdrop for the thorniest problem in all of climate science: how haze and clouds interact to influence global warming. In August, NASA aircraft began to tackle this mystery by studying a natural atmospheric laboratory off the coast of Namibia, where a layer of smoke from fires in Africa wafts over a low cloud deck.

Polio returns to Nigeria

Nigeria was about to declare victory over polio, thanks to successful vaccination campaigns like the one depicted. Then, in mid-August, the country reported two polio cases in children, after having gone 3 years without a case of the wild virus. Now, experts are concerned about a new outbreak.

A bonobo gets an eye exam

Humans aren’t the only primates that may need reading glasses. One of our closest cousins, bonobos, lose their vision as they age. Here are a couple of the apes engaged in an act of grooming, which looks suspiciously like a trip to the optometrist’s.

The lovely lichen

Lichens are a bizarre life form. A symbiotic partnership between fungus and an alga, scientists are still probing their mysteries. This specimen, Hypogymnia imshaugii, was attractive enough to make the cover of Science in July.

Peering beneath the surface of the moon

Forget about the dark side of the moon—what lies beneath its surface? Clues to mysterious impact crater rings, according to this subsurface map obtained from NASA’s Gravity Recovery and Interior Laboratory mission. The data could provide insight into other comet and asteroid strikes across the solar system.
