Scientists found the oldest material on Earth from an ancient meteorite
Scientists found a meteorite that was crashed into rural southeastern Australia in a fireball in 1969 contained the oldest material ever found on Earth. The stardust predated the formation of the solar system by billions of years.
The oldest of 40 tiny dust grains trapped inside the meteorite fragments were retrieved around the town of Murchison in Victoria state.
It dated back to about 7 billion years ago which is about 2.5 billion years before the sun, Earth and the rest of the solar system formed.
All of the dust specks that were analyzed in the research came from before the solar system’s formation which is known as pre-solar grains.
About 60% of them dated between 4.6 and 4.9 billion years old. Among the stardust, the oldest 10% dated to more than 5.6 billion years ago.
China operationalised the world’s largest radio telescope, FAST
China operationalized the world’s largest radio telescope in southwest China’s Guiyang city, the capital of Guizhou province. The FAST telescope is was launched after three years of trial operation.
The Five-hundred-meter Aperture Spherical radio Telescope (FAST) telescope is with a diameter of half-a-kilometer. It is dubbed as China Sky Eye.
The device is expected to make major scientific discoveries.
FAST is 2.5 times as sensitive as the second-largest telescope in the world.
It is capable of receiving a maximum of 38 gigabytes (GB) of information per second.
The receiving area of the telescope is around 30 football fields.
The cost of the telescope is around the US $170 million.
The telescope includes a 5 km radius as the core zone, 5 km to 10 km radius as the
intermediate zone and a peripheral zone that covers 10 km to 30 km in radius.
World’s First Transcatheter Mitral Valve Approved in Europe
The Abbott Tendyne Transcatheter Mitral Valve Implantation (TMVI) system received the European CE mark. It is the first transcatheter mitral valve replacement (TMVR) technology in the world.
The main aim is to make critical need to eliminate mitral regurgitation when surgery or mitral repair is not an option in high-risk surgical patients. This therapy treats significant mitral regurgitation (MR) in patients requiring a heart valve replacement.
Tendyne device builds upon our history of developing groundbreaking therapies that offer new treatment options for people with structural severe heart conditions who have limited treatment options. The Tendyne as a treatment option in Europe provides physicians with an additional tool that has been shown to correct MR in acutely ill patients completely, and it adds to Abbott’s portfolio of life-changing and life-saving treatments.
