What does a black hole really looks like?
We have seen many computer-generated images of black holes and know what a black hole looks like. But MIT researchers are aiming to go one step further. They have developed an algorithm that could help create the first ever actual image of a black hole.
The algorithm will stitch together data collected from radio telescopes scattered around the world and will construct images of black hole from visual information they receive. The images are expected to be reliable than ever before and hoping to meet certain expectations.
A latest research confirms the old myth about how electric eels protect themselves from predators. Electric eels actually sprang out of water and deliver a powerful shock to the object they perceive to be a threat.
A biologist have just demonstrated how electric eels rose up out of water and shocked a dummy alligator head. In the video, the head of the alligator can even seen lighting up when the eel shocks it.
The latest research adds weights to a legendary account by 19th century explorer Alexander von Humboldt, who said he witnessed electric eels leaping from the waters of Amazon and shocking horses.
Remembering and recognizing human faces is a difficult task, mainly due to the fact that all human faces share the same basic features. It becomes even more difficult for animals that have small and simple brains. But a new research suggests that some fish species can recognize human faces with remarkable accuracy. And it’s the first time when fish have demonstrated this ability.
The focus of the study was a tropical fish called archerfish which is known for its unique ability of knocking down its prey by splitting water droplets on it. For the study, fish was trained to recognize human face and to choose the familiar one among several new faces using its water jets.
Researchers found that fish was highly accurate when selecting the correct face.
The International Union of Pure and Applied Chemistry have proposed names for four previously unnamed elements. The new elements on periodic table are 113, 115,117 and 118 and have given names nihonium, moscovium, tennessine and oganesson respectively.
The four elements were officially recognized by IUPAC December last year and asked the scientists who had discovered them to name them as well. The names are on five-month probation before they become official.
All the newly-named elements are superheavy, radioactive which are not found in nature and are created in laboratories. The element 113 is the first to be discovered in an Asian country and the addition of all four elements have completed the seventh row of the periodic table.
A new research suggests that supermassive black holes eat up cold gas too.

Prior to this, researchers believed that huge black holes that lie in the center of the giant galaxies only feed on slow, steady diet of hot, ionized gas from the galaxy’s halo. But researchers have recently spotted three clouds of gas hurtling towards the edge of the black hole at a speed of almost 800,000 miles per hour, making it almost certain that they will fall into black hole and will likely be consumed by it. The findings can provide clues on how black holes throughout the universe manage to grow so large.
