Scientists have developed a new type of optical disc that can increase information storage capacity to the "petabit" level — 125 terabytes of data, or the combined storage capacity of about 15,000 DVDs.  Optical discs, such as DVDs and Blu-ray discs, are durable and inexpensive. A standard single-layer Blu-ray disc can store 25 gigabytes. By comparison, some USB flash drives can store 1TB, and hard disk drives (HDDs) can hold up to 16TB. But a team of scientists has created a new type of material, called "dye-doped photoresist with aggregation-induced emission luminogens" (AIE-DDPR) with a high areal density (the amount of data that can be stored in a given area) that can offer far denser storage capacity than typical HDDs).  Given the increasing amount of data we generate each day, from instant messages to streaming video, AIE-DDPR optical discs have the potential to revolutionize data storage. Optical discs take up less space than current storage methods, ...

Indian salt-to-software conglomerate Tata Group plans to open 100 stores across the country that will only sell Apple Inc products, the Economic Times newspaper reported on Monday, citing two people aware of the matter. Tata Group's Infiniti Retail, which runs the consumer electronics store chain Croma, will be an Apple-authorised reseller and set up stores at shopping malls, high-street and neighbourhood locations, the report said. Tata has begun talks with premium malls and high streets and the lease terms include details of brands and stores that cannot be opened near these outlets, a retail consultant aware of the matter told the publication. Apple and Tata Group did not immediately respond to Reuters' calls and emails seeking comment. The latest development comes less than two weeks after the Economic Times reported that the Tata Group was in talks to buy Wistron Corp's only manufacturing facility in India for up to 50 billion rupe...

Elon Musk on Wednesday tweeted that the misunderstanding about Twitter potentially being removed from Apple Inc's App Store was resolved following his meeting with the iPhone maker's Chief Executive Tim Cook. "Tim was clear that Apple never considered doing so," the billionaire CEO of Twitter and Tesla Inc said in a tweet. On Monday, Musk had accused Apple of threatening to block Twitter from its app store without saying why in a series of tweets that also said it had stopped advertising on the social media platform. He had later tagged Cook's Twitter account in another tweet, asking "what's going on here?" Twitter and Apple did not immediately respond to requests for comment on Musk's latest tweet. Apple has not responded publicly to Musk's earlier tweets. Among the list of grievances tweeted by Musk on Monday was the up to 30% fee Apple charges software developers for in-app purchases, with Musk posting a mem...
