New antiviral with 99.9% efficacy against Covid-19 developed
IANS -
Traditional antivirals, which include Tamiflu, zanamivir and remdesivir, reduce symptoms and help people recover earlier. The new antiviral approach used gene-silencing RNA technology called siRNA (small-interfering RNA) to attack the virus' genome directly.

On February 12, the Solar Orbiter caught sight of coronal mass ejection, or CME, NASA said in a statement. The CME was captured by NASA instrument, the Solar Orbiter Heliospheric Imager (SoloHI) onboard the spacecraft. SoloHI watches the solar wind, dust, and cosmic rays that fill the space between the Sun and the planets. It used one of its four detectors at less than 15 per cent of its normal cadence to reduce the amount of data acquired.

Covid-19 can infect cells in eye: Study
IANS -
A new study by the Mount Sinai Hospital researchers found that cells in the eye can be directly infected by SARS-CoV-2. While aerosol transmission is thought to be the primary route of spread, viral particles have been detected in ocular fluid suggesting the eye may be a vulnerable point of viral entry.

Covid monoclonal antibodies cut hospitalisation, death risk by 60%

Monoclonal antibodies are a type of medication that seeks out the Covid-19 virus in a person's body and blocks it from infecting their cells and replicating. The study, led by University of Pittsburgh researchers found that people aged 65 and older who received bamlanivimab -- a monoclonal antibody -- were nearly three times less likely to be hospitalised or die in the following month, compared to their untreated counterparts.

"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.
