What’s the photoelectric effect? Well, we have the genius himself to thank for explaining this production and transformation of light when he won the Nobel Prize in Physics 86 years ago. After you’ve conjured up a visual of his crazy white hair, read on for our electrifying updates.

• Courtside seats all season: Now get all your NBA video highlights from every regular and post-season game on Yahoo! Sports (better than just the post-season action we had last year, eh?). We’ve even added on-demand access to expert analysis from our NBA analysts Kenny Smith, and game previews during post season. Get a comfy chair, you’ll need it.
• Of weather and money: My Yahoo! has improved two key tools, just in time for winter travels. The currency converter now features a customizable grid that lets you compare multiple currencies (from more than 150) at once so your head won’t hurt when you plan treks to many countries. And our new weather module lets you get the current climate report for your destination by letting you choose from three modes (full, classic or compact). You can also get detailed forecasts by mousing over your city, get more readable three-day forecast, and set up alerts. Making multiple stops? Search for additional locations right within the module.
• Calling all bloggers: Think you’ve got what it takes to show you’ve got the best blog community? If so, join the MyBlogBlog Problogger contest to win a bunch of prizes and tools to make your blog the best it can be. Blogger snacks for the grand-prize winner include a pro MyBlogLog subscription, a $500 Yahoo! Search Marketing credit, and a complete blog redesign. All you have to do is be the community that grows the most (that’s gross total from now to November 30, 2007). See the official rules here and read more about the contest here.
