Fruit flies are hard to swat. Mapping their brain might tell us why
Fruit fly brains are smaller than a poppy seed, but that doesn't mean they aren't complex. For the first time, researchers have published a complete diagram of 50 million connections in an adult fruit flies brain. The journal Nature simultaneously published nine papers related to this new brain map. Until now, only a roundworm and a fruit fly larva had been mapped in this way.

How do scientists study lightning? With a spy plane and some big storms
Lightning: It happens all the time, and yet the exact details of how it's made has long eluded scientists. That is, until now. New research out this week in the journal Nature holds new insights into the precursor to lightning. To figure it out, researchers flew a NASA ER-2 - essentially the research version of a spy plane - over several tropical thunderstorms. What they found: The same high energy radiation is found in places like neutron stars and around black holes.

India's plan to reroute rivers could have unintended consequences on rainfall

It's the largest project of its kind and will take decades to complete. But scientists are worried what moving that much water could do to the land, the people — and even the weather.

Historic numbers of animals across the globe have become endangered or pushed to extinction. But some of these species sit in limbo — not definitively extinct yet missing from the scientific record. Rediscovering a "lost" species is not easy. It can require trips to remote areas and canvassing a large area in search of only a handful of animals. But new technology and stronger partnerships with local communities have helped these hidden, "uncharismatic" creatures come to light.

Most animals don't go through menopause. So why do these whales?
Across the animal kingdom, menopause is something of an evolutionary blip. We humans are one of the few animals to experience it. But Sam Ellis, a researcher in animal behavior, argues that this isn't so surprising. "The best way to propagate your genes is to get as many offspring as possible into the next generation," says Ellis. "The best way to do that is almost always to reproduce your whole life."

So how did menopause evolve? The answer may lie in whales. Ellis and his team at the University of Exeter recently published a study in the journal Nature that studies the evolution of menopause in the undersea animals most known for it. What they uncovered may even help explain menopause in humans.
