Oxford University, Oracle join hands to identify Covid-19 variants
"This powerful new tool will enable public health scientists in research establishments, public health agencies, healthcare services, and diagnostic companies around the world to help further understanding of infectious diseases, starting with coronavirus," said Derrick Crook, Professor of Microbiology in the Nuffield Department of Medicine at the University of Oxford, in a statement.
Supercomputer simulations unlock old space weather puzzle
When the solar wind hits the Earth, it is almost 10 times hotter than expected, with a temperature of about 100,000 to 200,000 degrees Celsius. The outer atmosphere of the sun, where the solar wind originates, is typically a million degrees Celsius. The solar wind stays hot for longer because of small-scale magnetic reconnection that forms in the turbulence of the solar wind.
Uncontrolled diabetes major cause of Black Fungus: Experts

"The patient presented to his primary care physician with complaints of swelling in his left arm and was sent to the hospital for further management where he was diagnosed with an upper arm blood clot and an asymptomatic Covid-19 infection," said Payal Parikh, assistant professor of medicine at Rutgers Robert Wood Johnson Medical School, who led the study.
Scientists spot genes linked with severe Covid-19 risk
DNA is a big, complex molecule and so, genetic associations alone cannot pinpoint the exact gene responsible for Covid-19. "However, by combining Covid-19 genetic information with gene expression and proteomic datasets, we can figure out which genes are driving the relationship with Covid-19," explained Ana Hernandez Cordero, postdoctoral fellow with the Centre for Heart Lung Innovation, University of British Columbia.

"It's another important milestone for China's space exploration," he said.
2-DG drug cuts down oxygen demand in Covid-19 patients: Process co-inventor
"The 2-DG drug impacts the cells that are affected by coronavirus and prevent their multiplication. The drug will not affect the good cells," Rakesh Kumar Sharma, Vice Chancellor, Saveetha Institute of Medical and Technical Sciences (SIMTS) here. Sharma was one of the co-inventors of the improved process of 2-DG when he was with the Defence Research Development Organisation (DRDO).
Covid outcomes may be more severe in children: Study
The study led by researchers at University of Alabama - Birmingham, US, found that children with Covid-19 may develop poor clinical outcomes such as requiring hospitalisation, critical care services and mechanical ventilation. For the study, the team identified nearly 12,000 pediatric Covid-19 patients.
