It's time for "Nerd News," covering the most important news for your brain you may have missed over the last few days. Here's a quick rundown of this week in science . . .

1. Engineers at the University of Wisconsinhavedeveloped a new hat that uses electric pulses to stimulate hair growth. And they think it could eventually lead to a cure for baldness, or at least prevent hair loss.

2. A newstudyfound North America has lost THREE BILLION birds over the last 50 years, or about 25% of the population. Three main causes are pesticides . . . land development . . . and the fact that we have a lot more cats than we used to.

3. Back in June, there was areportthat claimed humans were growing SPIKES in the backs of their heads from staring at their phones too much. Now the authors of the study are walking back those claims. And itlookslike it's probably not true.

4. There's a newrecordfor the "blackest black" material ever made. A team at M.I.T. created a foil out of nanotubes that absorbs 99.995% of light. The previous record holder was a material called "Vantablack," which absorbs 99.965%.

5. And a team of anthropologists in New Yorkthinkthey've figured out what killed off the Neanderthals. The answer . . . too many ear infections.
