Mark Zuckerberg apologized for not doing enough to stop the spread of misinformation on Facebook ahead of the 2016 election

Leading up to the 2016 election, misinformation about both Donald Trump, Hillary Clinton, and even Barack Obama flourished on Facebook. In the final stretch leading up to the election, more than one-quarter of Americans visited a fake news site supporting either Trump or Clinton. Many fake news studies have widely different methods of measuring and assessing the impact of fake news, so the actual impact it had in the 2016 election is unclear.

Though many scientists believe fruit bats are the reservoir species for the virus, Ebola viral RNA fragments were detected in a greater long-fingered bat captured in 2016 in Liberia. The species isn't a fruit bat—it roosts in caves and feeds on insects.

Although Mars does not feature liquid water on its surface, geological features provide evidence that the Martian surface experienced massive flooding in the distant past.

The presence of structures known to be carved by water on Earth, including river valleys, canyons, and lakebeds, has led scientists to infer that water flowed abundantly across Mars' surface.

The layering of rocks in the walls of geological structures shaped by water on the Martian surface indicates the intensity and volume of past water flows.
With a weaker gravitational field and no magnetic field to shield it from charged particles emitted by the sun, Mars' atmosphere and surface water were lost early in its history.
Volcanic landforms and igneous rocks indicate that Mars was once volcanically active, but the dormancy of its volcanoes cut off the surface from receiving new water vapor via volcanic gases.
Mars features extensive sheets of perennial water ice and carbon dioxide ice at its poles, and reservoirs of frozen water have been detected beneath surface layers of dust and rock.

While published images have suggested that Neptune is much bluer than Uranus, the two ice giants are a similarly pale shade of greenish-blue.

Uranus and Neptune appear bluish primarily because their atmospheres contain trace amounts of methane, which reflects blue light and absorbs red light.

Some published images of Neptune and Uranus from the 20th century involved combining images taken in different colors, which were not accurately balanced during processing.
Early images of Neptune from NASA's Voyager 2 mission were "strongly contrast-enhanced to better reveal the clouds, bands, and winds."
More accurate, rebalanced images of Uranus and Neptune were created using instruments on the Hubble Space Telescope and the Very Large Telescope, with each pixel capturing the full color spectrum.
Color-rebalanced imaging revealed that Uranus, which spins on its side, appears greener at its solstices and bluer at its equinoxes because its polar and equatorial regions reflect light differently.
