A very hungry blackhole 

• Astronomers at the SkyMapper Southern Sky Observatory (in pic) in Australia have discovered a black hole that’s 20 billion times the mass of the sun and eating the equivalent of a star every two days. The blaze from material swirling around this newly observed blackhole is as luminous as 700 trillion suns — so dazzling bright that we cannot see the galaxy it lives in.The discovery was announced in the Publications of the Astronomical Society of Australia.   

Virtual me

• In a study at the Toyohashi University of Technology in Japan, volunteers wearing virtual reality headsets and motion sensors watched disembodied hands and feet move two metres in front of them in a virtual room. When the hands and feet mirrored participants’ own movements, people reported feeling as if the space between the appendages were their own bodies. The work fits into a corpus of research on illusory body ownership, which has contributed to therapies like treating pain for amputees who experience phantom limb. 

Memory gain

• In a paper published in eNeuro, scientists at the University of California in Los Angeles reported that when they transferred molecules from the brain cells of trained snails to untrained snails, the animals behaved as if they remembered the trained snails’ experiences.
