PROBLEM: CLEVELAND (AP) â  LeBron James  couldnât get to 30 000 career points and  he  and  his  Cleveland teammates couldnât stop Paul George  Russell Westbrook or Carmelo Anthony as the Oklahoma City Thunder thumped the Cavaliers 148-124 on Saturday for their fourth straight win.
 James  finished with 18 points and is seven shy of becoming the seventh player in NBA history to reach the 30 000-point plateau.  His  next chance is Tuesday when the Cavs visit San Antonio.
 James  entered the fourth within reach of 30 000. But after  he  missed two shots   James  was replaced with 6:37 remaining and the Cavs trailing 128-101. The 33-year-old wanted to make history in front of  his  home fans and family  but it wasnât to be and  he  dejectedly took a seat on the bench as the Thunder finished off the rout.
 James  will eventually get to 30 000 and join Kareem Abdul-Jabbar (38 387 points)  Karl Malone (36 928)  Kobe Bryant (33 643)  Michael Jordan (32 292)  Wilt Chamberlain (31 419) and Dirk Nowitzki (30 808) on the select list.
The Cavs made one last push with  James  making a layup to cut the Thunderâs lead to 12. But Oklahoma City didnât let up and eventually pushed the lead to 31.
Thunder: G Andre Roberson played his second game after missing eight with left patellar tendinitis. He had a forgettable six-second span  missing four straight free throws and committing a foul. â¦ Coach Billy Donovan first watched  James  play as a high school sophomore  when he stood out more than others. âIn seeing him at that age you see a lot of times young kids that are sophomores with his ability â maybe not all of his ability â but you see talented players â Donovan said. âThey never get better. A lot of times itâs difficult to get better because thereâs such a microscope. The thing thatâs amazing to me is heâs had a lot of attention on him and a very  very young age and he always got better.â

PROBLEM: Billions of years ago  Mars was likely much wetter than it is today. The ice has a series of layers  says  Colin Dundas   a planetary geologist at the U.S. Geological Survey and the paper's lead author. Those newly detected layers suggest that the ice was laid down over a period of time  through a process that happened repeatedly.
"Something caused it to be deposited and then deposited again " says  Dundas . That thing was likely snowfall   Dundas  says  which was eventually compacted into these deposits. The snowfall could have happened as recently as tens of millions of years ago  he says.
The scientists think the exposed ice is not stable at the relatively warm surface temperatures.  Dundas  says ice at the surface is transforming from solid into vapor  causing the slopes to collapse and become further exposed.
There have also been significant questions about how pure Mars ice is. But  Dundas  says that "at these locations  its  quite a thick ice sheet of rather clean ice."
