Scientists Create Special Camera to Study Glow-in-the-Dark Sharks

For the first time, researchers have found a way to figure out how sharks living in the depths of the oceans see each other.

For this purpose, they have created a special camera which enabled them to look at the underwater world through the eyes of the shark which was otherwise not possible to see for humans. Researchers found that a group of sharks known as catsharks produce bright green light only visible to the members of their own species. Furthermore, the contrasts of glowing pattern continue to increase with depth, indicating that sharks not only use glow to see each other but also to communicate with one another.  

New Species of Long-Necked Dinosaur Discovered in Argentina 

Researchers have recovered a new species of titanosaurian dinosaur in Argentina. The new species, called Sarmientosaurus musacchioi, had small head but exceptional vision and sensing abilities which were not observed in other dinosaurs related to this group.

Titanosaurs, a type of sauropod, were the largest and one of the most common group animals to have existed on Earth. Despite their abundance, a very limited number of titanosaur skulls have been discovered until now. Therefore, the discovery is important and it may provide more insight into the group of long necked, plant eating titanosaurian dinosaur.

Hubble Finds a Tiny Moon Orbiting a Dwarf Planet at the Edge of our Solar System 

Hubble space telescope recently found a tiny moon orbiting a dwarf planet in the distant outskirts of our solar system.

The moon nicknamed MK2, orbits Makemake, second brightest dwarf planet Pluto in the Kuiper belt and is really tiny and dim – almost 1,300 times fainter than Makemake. The diameter of the moon is just 100 miles compared to the diameter of dwarf planet which is 870 miles.

This is the first discovery of a companion object to Makemake and finding a moon orbiting Makemake reinforces the idea that most dwarf planets have objects orbiting around them.

Scientists Develop Brain Atlas that Shows How Human Brain Organizes Language 

Scientists have been able to create a “semantic atlas” that shows how human brain organizes language and respond to the words that have similar meanings. The vivid colors and multiple dimensions in the atlas represent neural activity which is triggered by listening to different words.

Words and concepts can be noticed clustered in very specific regions of cortex. More importantly, people who are very different from each other tend to share similar language maps.

Weird Tailless Comet Discovered in the Inner Solar System  

Astronomers have discovered a tailless comet in our solar system which is the first of its kind and it may help solve longstanding questions about the formation and evolution of solar system and Earth-like planets. They called it a Manx comet, named after a breed of cats without tails.

Researchers believe that the comet was born at the same time as the Earth itself and was a part of the planets in our solar system. But somehow it got ejected from the inner solar system and remained preserved in the deep freeze of Oort Cloud for billions of years. Now, the comet is making its way back into its birthplace.
