PROBLEM: Researchers have discovered four extinct underwater volcanoes thousands of feet below the water off the coast of Sydney The calderas are believed to have formed 50 million years ago when supercontinent Gondwana was splitting up into the regions we now know as Australia and New Zealand. And this quartet of 'hotheads' may offer geologists clues about how exactly this tectonic movement took place. The volcanoes were discovered 125 miles (200km) off the southwestern Australian coast using the Investigator ocean explorer from the Commonwealth Scientific and Industrial Research Organisation (CSIRO). Scientists from the University of New South Wales Australia were searching for nursery grounds for larval lobsters when the sonar images spotted the volcanoes 16,100 feet (4,900 metres) underwater.Four volcanoes found in a cluster 125 miles (200km) off coast of SydneyResearchers found the ancient underwater formation by accidentCluster is 12 miles (20km) long, 4 miles (6km wide) and rises 230ft (700m)Experts believe they tell 'part of the story' of how Australia and New Zealand separated between 40 and 80 million years ago

PROBLEM: This is the moment a group of terrified African migrants were photographed clinging on for dear life after the barely seaworthy boat they were using to make the extremely dangerous passage across the Mediterranean Sea began to sink. More than 450 migrants desperate for a new life in Europe were crammed on board the former fishing vessel when it went down just 20 miles off the northern coast of Libya. Only the lucky few seen in the photographs - which were taken from a passing aircraft - were able to survive the disaster, clinging to the tiny tip of the hull that remained above the water after hundreds of their friends and family members sunk to their tragic deaths.More than 450 migrants desperate for a new life in Europe were crammed on board the former fishing vesselThe boat bound for the Italian mainland went down just 20 miles off the northern coast of LibyaOnly a lucky few seen in the photographs were able to survive the disaster - with hundreds of others dyingPassengers on board a passing plane were able to alert the Italian Coast Guard who sent a rubber dinghyBut that craft was overwhelmed by the desperate migrants and also started to sink in the merciless sea

PROBLEM: (CNN) -- At the beginning of 2008, everything seemed set for Bill Clinton. His wife, Hillary, had the money and the endorsements to run for the presidency. She also had the experience and the talismanic Democratic last name. Everything was in place for Bill's return to the White House, this time as first gentleman. Then came Iowa, when the supposedly unstoppable Hillary for president locomotive was derailed by Barack Obama, a first-term senator from Illinois. Bill Clinton couldn't believe that this Johnny-come-lately might block his wife's path to the White House. Bill Clinton and Barack Obama may be making common cause now, but four years ago the future president drove the former president crazy.President Obama has actively embraced Bill Clinton for help on raising money and gaining votersMichael Takiff: Obama needs Clinton in his campaign, Clinton craves political relevanceHe says four years ago, Obama drove the former president crazyTakiff: Whatever his feelings toward Bill Clinton, Obama should listen to him
