Fiction as an empathy workout. What makes bookworms such bleeding hearts? A new study led by P. Matthijs Bal ofVU University in the Netherlands finds that readers who emotionallyimmerse themselves with written fiction for weeklong periods can help boost their empatheticskills. The researchers discovered this by having university students read either fiction by Sir Arthur Conan Doyle andJos Saramagoor items from a newspaper. Gauging the participants'empatheticabilities and self-reported emotions before and after such reading sessions, they found that the fiction readers got more of an emotional workout than the nonfiction readers. And they became noticeably more empathetic after a week of such experiments. 
This is the first fMRI video of a human fetal brain. The video below, taken by Wayne State University's Moriah Thomason, is the first fMRI footage we have of a human fetus' brain as it develops in the womb. Such technology allowed Thomason to determine the timeline of neural development for fetuses. Researchers think such information could help doctors diagnose conditions like schizophrenia and autism before birth, opening up a whole can of bioethical worms. The new footage followsto capture a baby's brain while the baby was being born. 
Siberia's permafrost is melting. New research in Siberian caves shows that the permafrost in Russia's chilly northernmost region is melting quicker than we thought. A new paper in Scienceput together by an international team of researchers finds that the "permafrost frontier" is set to thaw as a 1.5 Celsius temperature increasein the near future. "As permafrost covers 24% of the land surface of the Northern Hemisphere, significant thawing could affect vast areas and release (billions of tonnes) of carbon," the University of Oxford's Anton Vaks says.The researchers find that as much as a trillion tons of greenhouse gases would be released into the atmosphere if climate change progresses undeterred. 
Vision via microchip. A week after the FDAthe first bionic device that provides vision to the blind, a German medical technology company called Retina Implants says that it has developed a microchip that provides limited vision to some blind people without external devices. The microchip would be wirelessly controlled, and would allow people with certain types of inherited blindness to perceive light, roughly detect objects, and in some cases read letters. "The very personal things, such as if a mouth is smiling, or the shape of a nose, are the most exciting for them," says lead researcher Katarina Stigl of the University of Tubingen, describing the eight out of nine patients who successfully saw things in clinical trials with the microchip.
