3D-printing applications are becoming common in manufacturing, art design, product development, and architecture. Recent innovations are advancing how artificial tissues and human organs can be created using bioprinting. Researchers at UC Berkeley found that using cryogenic techniques they were able to speed up the printing process by stacking 2D layers of cells and binding them together into a 3D structure. . Bioprinting is an area where 3D-printing techniques have been applied to the fabrication of bioparts and tissues using living cells. Bioprinting is increasingly being used in medicine and bioengineering. Rohan Shirwaiker, NC State associate professor, said that “we’ve reached the point where we are able to create medical products, such as knee implants, by printing living cells. But one challenge has been organizing the cells that are being printed, so that the engineered tissue more closely mimics natural tissues.” At NC State an ultrasonic technique was used to better control the alignment of cells during the printing process, allowing researchers to precisely control cell placement to achieve improved strength and flexibility characteristics. The 3D Bioprinting market was $385 million in the US in 2018 and is growing at a rate of 25 percent annually, according to ResearchAndMarkets.com. Zichen Ziao, UC Berkeley Researcher, described the technique, saying that “it’s like making a hamburger in a very cool — cryogenic — solution. You already print multiple layers, and you basically pick up one layer and stack them on top of each other. You put the bottom bread there first and put whatever layer you want on top of it. By the process of freezing, it keeps its rigid structure, and the cells are still alive.”
Veteran Indian batsman Rahul Dravid was on Friday named captain of the Indian Premier League team Rajasthan Royals, replacing Australian spin legend Shane Warne who quit the IPL after the fourth edition earlier this year.”…gotta make another huge announcement,The New Captain fr Rajasthan Royals..Proud 2 have RAHUL DRAVID head the Team this season.Yipee,” tweeted the franchise’s co-owner Shilpa Shetty.”So its Official now!The “WALL” it is;)Congratulations Rahul, am sure u will make us all very proud at RR..Go Royals,” she added.The fifth edition of the Twenty20 league will be played from April 4 to May 27 next year.The 38-year-old Dravid, who was part of Royal Challengers Bangalore team to start with, was bought by the Rajasthan team for USD 500,000 in the players’ auction before the start of IPL 4 this year.Rajasthan was without a captain after Warne announced his retirement from the IPL in May this year.The 42-year-old Warne, who coached and captained Royals since the first edition in 2008, is currently playing in the Australian Big Bash Twenty20 Tournament for the Melbourne team.Dravid was reasonably successful in his debut season for the Royals this year, scoring 343 runs at an average of 31 in 12 matches.
