Currently cardiologists can tell from the timing of the heartbeat in scans if there is a problem. However, even the best doctors get it wrong in one in five cases. LONDON: Researchers in the UK have developed new artificial intelligence ( AI ) systems which can help diagnose heart disease and lung  cancer  much more accurately and early. Currently cardiologists can tell from the timing of the heartbeat in scans if there is a problem. However, even the best doctors get it wrong in one in five cases. Patients are either sent home and have a heart attack or they undergo an unnecessary operation.

The moves undertaken by local and global internet players clearly indicate that the strong are getting stronger in the Indian internet ecosystem. When online grocer  Bigbasket  went to market in early 2017 to raise capital just a year after securing $150 million, the list of suitors was very different. In March 2016, it had closed funding from US- and Middle East-based financial investors including Sands Capital, IFC and Abraaj Capital. This time, the interested ones were major corporations—Chinese strategic investors  Tencent , conglomerate Fosun, ecommerce giant  Alibaba  along with Paytm Mall, and, of course, US-based  Amazon .
