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."
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.
- 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.

Progressive America would be half as big, but twice as populated as its conservative twin.
- 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
The definition of a kilogram will now be fixed to Planck's constant, a fundamental part of quantum physics.
- 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.
