Missing Link

Scientists have found a couple of 1.9-million-year-old skeletons in a South African cave that may be "a Rosetta Stone for defining for the first time what the genus Homo is."

Scientists have found a couple of 1.9-million-year-old skeletons in a South African cave that fill in another clue from our primate past. Named australopithecus sediba, these skeletons have many features common to our genus, but also have extra-long forearms and flexible feet -- characteristics that date from deep in our primate past. It is unclear whether the skeletons belong to a direct human ancestor, but the fossils provide insight into an unknown period. "We feel that A. sediba might be a Rosetta Stone for defining for the first time what the genus Homo is," said paleontologist Lee Berger. "They’re going to be a remarkable window, a time machine."

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.

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.
