Lightest Form of Uranium

  • The scientists have created the lightest form of Uranium. It is called the Uranium-214. The discovery reveals more information about an alpha particle. The alpha particles are those particles that get ejected from radioactive elements as they decay.
  • This isotope of Uranium has a greater number of neutrons than protons. The neutrons have mass. However, Uranium-214 found recently is much lighter than the other common Uranium isotopes. This includes Uranium-235 as well. Uranium-235 is the most commonly used isotope. It has 51 extra neutrons.
  • Uranium-214 was created at the Heavy Ion Research Facility in Lanzhou, China.
  • It had a half-life of just half a milli-second. The half life of a radioactive sample is the time taken for half of the radioactive sample to decay. The half life of Uranium-238 is 4.5 billion years. This is the almost equal to the age of the earth.

NASA's Crew-1 Astronauts Safely Splash Down

  • NASA's Space X Crew-1 astronauts truly deserve a big hand as after surviving 167 days in space, the longest duration mission for a U.S. spacecraft since the final Skylab mission in 1974, Dragon and the Crew-1 astronauts returned safely to Earth.
  • The four Crew-1 astronauts splashed down in the Gulf of Mexico right on schedule, returning to Earth after a six-month stay on the International Space Station.
  • The astronauts — three Americans and one from Japan — had undocked from the station, flew through the atmosphere and then touched down in the Gulf of Mexico under four massive parachutes.

Vodafone Joins Google Cloud on Data Analytics

  • Vodafone Group PLC and the cloud division of Alphabet Inc.'s Google are planning to jointly develop data services, citing interviews with representatives from both companies. As per reports, about 1,000 workers in the U.K., Spain and the U.S. will be asked to create "Nucleus," the new cloud-based storage and analytics portal, which will host Vodafone's data. Nucleus will be able to process around 50 terabytes of data a day within the cloud.
  • As part of the six-year agreement Vodafone will transfer data from its own servers to Google Cloud.
  • Vodafone and Google will also invent a system, called Dynamo, that will extract and transport data across different countries where the telecoms company operates.
  • The two companies will also in the future seek to sell consultancy services to other multinational businesses seeking to move huge amounts of data to the cloud.

NASA Astronaut Harvests Two Plants in Space

  • NASA's Expedition 64 crew member Michael Hopkins harvested two crops in space -- amara mustard, and a previously grown crop, extra dwarf pak choi.
  • They were grown for 64 days, the longest leafy greens have grown on station, the US space agency said. The pak choi grew for so long that it began to flower as part of its reproduction cycle. Hopkins' efforts in eclipsing the mark included using a small paintbrush to pollinate plant flowers. A VEG-05 experiment with dwarf tomatoes is planned for next year.
