Mumbai, Jan 14: Shikhar Dhawan hit a half-century before Australia pulled things back to bowl India out for 255 in the first ODI of the three-match series here on Tuesday.

Dhawan looked in great touch during his 91-ball 74 and, in the company of K L Rahul (47), shared a second-wicket stand of 121 runs off 136 balls to set the base for India's total. However, India failed to capitalise.

Sent into bat, India were dealt an early blow when they lost Rohit Sharma (10), caught by David Warner at mid-off off Mitchell Starc (3/56).

Rahul joined Dhawan at the crease and the duo played fluently without much trouble against a formidable Australian attack.

After adopting a cautious approach initially, Dhawan upped his ante and started to play his shots, while at the same time gave due respect to the good deliveries.

Dhawan showed his class and played all kinds of shots to register his fifty in 66 balls with a single off leg-spinner Adam Zampa (1/53) in the 20th over.

Soon after reaching his fifty, Dhawan got a reprieve when he was dropped by Warner at midwicket off Ashton Agar (1/56).

The two went about their business in style, picking up runs off bad balls before both departed in consecutive overs.

Just three short of his fifty, Rahul gave a straight forward catch to Steve Smith at covers off Agar and then, in the next over, Dhawan was caught by Agar off Pat Cummins (2/44).

While Rahul hit four boundaries during his 61-ball knock, Dhawan's innings was laced with nine fours and one six.

Dropping himself to No. 4 to accommodate both Dhawan and Rahul in the side, Virat Kohli (16) was in attacking mode from the onset, but didn't last long as Zampa took a sharp catch off his own bowling to dismiss the Indian skipper.

Shreyas Iyer followed suit when Starc induced an edge an over later and Alex Carey did the rest behind the stumps.

Rishabh Pant (28) and Ravindra Jadeja (25) shared 49 runs for the sixth wicket before the duo perished in consecutive overs as India lost the plot.

Towards the end Kuldeep Yadav (17) and Mohammed Shami (10) struck some useful boundaries.

Bhubaneswar: A team of genomic researchers from two institutes has identified 73 novel variants of the COVID-19 strain in Odisha, its head has said.

The researchers are from CSIR-Institute of Genomics and Integrative Biology (IGIB), New Delhi and Institute of Medical Sciences and SUM Hospital, Bhubaneswar, he said.

"The research team, which carried out sequencing of 1,536 samples including 752 clinical samples, reported two lineages -- B.1.112 and B.1.99 -- for the first time in India," Dr Jayashankar Das, lead investigator and director (research) of the IMS and SUM Hospital, said on Friday.

If one gets to know the detailed character of the novel coronavirus, it will be very easy to treat patients and cure them, he said.

The research team, supported by the Council of Scientific and Industrial Research (CSIR), validated the most-advanced COVID-19 sequencing technology. This could be a potential high-sensitivity assay for the detection of SARS- CoV-2 with the additional advantage of enabling genetic epidemiology of SARS-CoV-2, Das said.

With this study, India has beaten 12 organisations in 10 countries to complete the first field validation and release the data online, he said, quoting a report by sequencing tech giant Illumina.

The IMS and SUM Hospital researchers are also undertaking the sequencing and analysis of 500 viral genomes to understand the mild, moderate and critical coronavirus infection along with its transmission capabilities, he said.

Besides, the study will help understand the vulnerability of the strains, new therapeutic target and new mutation in eastern India, especially in Odisha, Das said.

The rapid emergence of COVID-19 as a pandemic, which has affected millions of people across the world, has necessitated sensitive and high-throughput approaches for the diagnosis, surveillance and determining the genetic epidemiology of SARS-CoV-2, which will help in tracking strain information as well, he said.

Asked about the difference between RT-PCR test and COVID-19 sequencing tests, Das said, "The COVID-19 sequencing reports give the entire history of the coronavirus, while the RT-PCR tests only determine whether a patient is positive or negative for the infection."
