Iceberg Breakaway

An iceberg the size of Luxembourg which has broken away from Antarctica was caused by a collision with another iceberg rather than being a result of global warming.

An iceberg the size of Luxembourg which has broken away from Antarctica was caused by a collision with another iceberg rather than being a result of global warming. "An iceberg the size of Luxembourg has broken away from the Antarctic continent and is drifting towards an area of the Southern Ocean that plays a critical role in driving the world's ocean circulation – the global 'conveyor belt' of circulating sea water. The floating iceberg, which contains enough fresh water to supply a third of the world's population for a year, is 48 miles long, 22 miles wide, has a surface area of 965 square miles and an average thickness of 1,300 feet. It is one of the largest icebergs to be monitored by scientists. Researchers believe the iceberg may be big enough to interfere with the flow of extremely cold and salty water that naturally sinks to the seabed in this part of the southern hemisphere to form the deep current of water that is transported around the world along the sea floor. This ocean circulation transports heat and nutrients and is vital for the marine food chain as well as maintaining important currents, such as the Gulf Stream. The giant iceberg broke away from the Mertz Glacier tongue in East Antarctica about three weeks ago. The 'calving' occurred when another, equally large, iceberg rammed against the Mertz Glacier tongue. 'The calving itself hasn't been directly linked to climate change but it is related to the natural processes occurring on the ice sheet,' Rob Massom, a scientist at the Australian Antarctic Climate and Ecosystems Co-operative Research Centre in Hobart, Tasmania, told the news agency Reuters."

Why a federal judge ordered White House to restore Jim Acosta's press badge

A federal judge ruled that the Trump administration likely violated the reporter's Fifth Amendment rights when it stripped his press credentials earlier this month.

WASHINGTON, DC - NOVEMBER 16: CNN chief White House correspondent Jim Acosta (R) returns to the White House with CNN Washington bureau chief Sam Feist after Federal judge Timothy J. Kelly ordered the White House to reinstate his press pass November 16, 2018 in Washington, DC. CNN has filed a lawsuit against the White House after Acosta's press pass was revoked after a dispute involving a news conference last week. (Photo by Alex Wong/Getty Images)

  • Acosta will be allowed to return to the White House on Friday.
  • The judge described the ruling as narrow, and didn't rule one way or the other on violations of the First Amendment.

How to split the USA into two countries: Red and Blue

Progressive America would be half as big, but twice as populated as its conservative twin.

Strange Maps
  • America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
  • Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
  • Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America

Scientists just voted to change the definition of a kilogram

The definition of a kilogram will now be fixed to Planck's constant, a fundamental part of quantum physics.

Surprising Science
  • The new definition of a kilogram is based on a physical constant in quantum physics.
  • Unlike the current definition of a kilogram, this measurement will never change.
  • Scientists also voted to update the definitions of several other measurements in physics.
