1. Fish With "Hands" Are New Species



Using its fins to walk, rather than swim, along the ocean floor in an undated picture, the pink handfish is one of nine newly named species described in a scientific review of the handfish family released in May.

The new-species determinations were made based on a number of factors, including number of vertebrae and fin rays, coloration, the presence of scales and spines, and proportional body measurements, according to the review's author.

Even among the previously known species, the fish are poorly studied, the review authors added. Little is known about their biology or behavior.



2. Dead Sea Scrolls Mystery Solved?



The recent decoding of a cryptic cup, the excavation of ancient Jerusalem tunnels, and other archaeological detective work may help solve one of the great biblical mysteries: Who wrote the Dead Sea Scrolls?

The new clues hint that the scrolls, which include some of the oldest known biblical documents, may have been the textual treasures of several groups, hidden away during wartime—and may even be "the great treasure from the Jerusalem Temple," which held the Ark of the Covenant, according to the Bible.



3. Odd Species Found Off Greenland



Looking like a creature from the Alien movies, this nightmarish "longhead dreamer" anglerfish was until recently an alien species to Greenland waters (map).

The dreamer, which grows to a not-so-monstrous 6.7 inches (17 centimeters) long, is 1 of 38 fish species found around the Arctic island for the first time, according to a study released in February.

Ten of the species new to Greenland are new to science, too. All 38 were discovered since the last such survey in 1992.



4. Noah's Ark Found in Turkey?



A team of evangelical Christian explorers claimed they'd found the remains of Noah's ark beneath snow and volcanic debris on Turkey's Mount Ararat (pictured) in April.

But some archaeologists and historians took the latest claim that Noah's ark had been found about as seriously as they had past ones—not very.



5. "Yoda Bat," Other Rarities Found



This tube-nosed fruit bat—immortalized elsewhere as the "Yoda bat"—is just one of the roughly 200 species encountered during two scientific expeditions to Papua New Guinea in 2009, including a katydid that "aims for the eyes" and a frog that does a mean cricket impression, Conservation International announced in October.



6. Black Holes Contain Universes?



Like part of a cosmic Russian doll, our universe may be nested inside a black hole that is itself part of a larger universe.

In turn, all the black holes found so far in our universe—from the microscopic to the supermassive—may be doorways into alternate realities.

According to a mind-bending study released this past spring, a black hole is actually a tunnel between universes—a type of wormhole. The matter the black hole attracts doesn't collapse into a single point, as has been predicted, but rather gushes out a "white hole" at the other end of the black one, the theory goes.



7. Shapes Reveal "Lost" Amazon World



Hundreds of circles, squares, and other geometric shapes once hidden by forest hint at a previously unknown ancient society that flourished in the Amazon, according to a study released in January.

Satellite images of the upper Amazon River Basin taken since 1999 have revealed more than 200 geometric earthworks spanning a distance greater than 155 miles (250 kilometers).

The researchers behind the January study, though, estimated that nearly ten times as many such structures—of unknown purpose—may exist undetected under the Amazon's forest cover.




8. Lizard Evolving for Live Birth



Evolution has been caught in the act, according to a study we covered this summer suggesting that a species of Australian lizard is abandoning egg-laying in favor of live birth.

Along the warm coastal lowlands of New South Wales (map), the yellow-bellied three-toed skink lays eggs to reproduce. But individuals of
the same species living in the state's higher, colder mountains are almost all giving birth to live young.




9. Hints of "Structures" Beyond Universe



"Dark flow" is no fluke, suggested a March study that strengthened the case for unknown, unseen "structures" lurking on the outskirts of creation.

In 2008 scientists reported the discovery of hundreds of galaxy clusters streaming in the same direction at more than 2.2 million miles (3.6 million kilometers) an hour.

This mysterious motion can't be explained by current models for distribution of mass in the universe. So the researchers made the
controversial suggestion that the clusters are being tugged on by the gravity of matter outside the known universe.

In the 2010 study the same team found that the dark flow extends even deeper into the universe than previously reported: out to at least 2.5 billion light-years from Earth.




10. Quake Altered Axis, Changed Time



February's Chile earthquake was so powerful that it likely shifted an Earth axis and shortened the length of a day—a NASA revelation that helped make this story National Geographic News's tenth most visited of 2010.

By speeding up Earth's rotation, the magnitude 8.8 earthquake—the fifth strongest ever recorded, according to the USGS—should have shortened an Earth day by 1.26 millionths of a second, according to new computer-model calculations by geophysicist Richard Gross of NASA's Jet Propulsion Laboratory in California.
