Coffee Could Be Extinct by 2080 Start drinking all the coffee you can find because it may be gone by 2080. A new study by the Royal Botanic Gardens in England says that 99.7 percent of Arabica coffee-bean growing areas will be affected by rising temperatures caused by climate change. Researchers said that wild Arabica XXX could be extinct by 2080 and that the bean makes up 70 percent of the global coffee market. Coffee farmers will have to create new farming techniques including cooling equipment in order to sustain Arabica farms.

More Woman Than Men With Driver's Licenses A new study by the University of Michigan's Transportation Research Institute said that more women have driver's licenses than men. The study looked at gender trends in driver's licenses between 1995 and 2010 and also found that the number of teens and young adults of both sexes with driver's licenses was declining. And if this decline continues, the gap between the sexes will only widen. Researchers said this trend would likely lead to safer, smaller and more fuel-efficient cars, fewer miles driven and lower fatality rates.

New Coach for the Lakers After just five games into the season, Los Angeles said "Goodbye" to Lakers coach Mike Brown and "Hello" to Mike D'Antoni. D'Antoni and the Lakers have agreed to a three-year deal for $12 million. The Lakers had been originally courting Phil Jackson, who reportedly wanted too much money and a year-to-year deal, which the Lakers disagreed with. D'Antoni was the next choice. Bernie Bickerstaff will likely remain as the interim coach through Tuesday to give D'Antoni a few practices with the team.
