Here is a summary of the five most popular science stories appearing this week in Science Recorder (Nov. 16-Nov. 22). Enjoy!
While the Hawaii Department of Land and Natural Resources is putting a new coral reef management plan into effect, many people are saying it does not go far enough.
Some are calling for an emergency moratorium on fishing for the profitable aquarium market, saying the state’s Kona Coast supplies nearly 70 percent of all aquarium fish caught near the islands. This is because aquarium fish, which are herbivores, help keep coral reefs free of the algae that damage them.
A newly found fossil of a winged pterosaur was recently discovered in northern Texas. The find is important because evidence of ancient pterosaurs in North America is rare.
The researchers says that the close relationship between pterosaurs from Texas and those found in England suggest that the creatures were able to spread to different parts of the globe even as the continents were drifting further apart.
A new study has uncovered a previously unknown secret about songbird behavior: They tap dance when flirting with potential mates.
Researchers used high-speed cameras to detect the birds’ fancy footwork, which is otherwise invisible to humans. They found that both males and females perform courtship displays with equal skill.
A new study finds that declining snow deposits in the Northern Hemisphere could lead to a widespread water crisis affecting more than 2 billion people. The reduced snowpacks around the world are caused by continually increasing global temperatures.
Researchers also believe the snowpack reduction could lead to more forest fires, the destruction of important ecosystems, and reduce access to clean water in under-developed countries.
Astronomers have stumbled upon a strange anomaly: A nearby dwarf galaxy that appears to contain one of the largest concentrations of dark matter ever recorded.
Dark matter particles make up some 85 percent of the matter in universe and interact with normal matter only by means gravitational force.
