The recently discovered fossil of a “feathered” dinosaur in China was about the size of a school bus, the prestigious science journal Nature reports. There are even possibilities that the larger ones may have been warm-blooded. Dubbed as the “little brother” to the Tyrannosaurus rex, the newly-discovered species was named the “Yutyrannus huali”, which, in Mandarin and Latin languages, means “beautiful feathered tyrant.”

Kristi Curry Rogers, a paleontologist from Macalester College, told Steven John of NPR’s All Things Considered on April 6 that it was the largest dinosaur to be found with well-preserved feathers, weighing over 3,000 pounds.

The Google logo on its home page has been replaced with an animated image of waves on a graph to mark the 155th birthday of Heinrich Rudolf Hertz, the legendary German physicist known for his groundbreaking work on electromagnetic waves. The animated waves shown in the Google doodle are in the search engine’s trademark colours; blue, red, yellow and green.

A group of researchers at the University of California, Berkeley have unveiled a new computer program for decrypting human brainwaves and then converting them into words. After running the pattern of brainwave through the software, they claimed they were able to convert the thoughts into actual words.

The results could be helpful in future while communicating with patients who can’t talk.

Legendary physicist Stephen Hawking celebrated his 70th birthday at Cambridge University, England, discussing the nature of the universe and topics related to supernovae, black holes and dark matter.

One of the most famous scientists alive today, Hawking is famous for popularizing the work of theoretical astrophysicists with this best-sellers A Brief History of Time and The Universe in a Nutshell.

Scientists are working on special robots that will help people cope with strokes. The project that involves three years aims to manufacture robotic devices that will produce repetitious motion of hands and wrists in the chronic phases of stroke rehabilitation.

The researchers at the University of Hertfordshire report that using the robotic devices and an interactive game-based interface, the therapy would be more easier and gratifying as compared to older processes of asking a patient to press a sponge ball with their fingers. In addition, the patient recovery would also be bettered with the introduction of these motivational devices available for home use.
