Moms with COVID-19 who take basic precautions rarely pass the novel coronavirus to their newborns, even if breastfeeding, according to a new study which says more extensive measures like separating the infected mothers from their babies may not be warranted.

Scientists have developed a new method of testing for COVID-19 that doesn't make use of key reagents but still delivers an accurate result, an advance that may lead to an inexpensive diagnosis technique in developing countries where chemical supplies are in short supply.

 Scientists have found the first compelling evidence that two groups of ecologically important marine microorganisms could be eating viruses -- catching their "prey" and engulfing them, an advance that may lead to a better understanding of the flow of organic matter in the oceans.

Scientists examined the effectiveness of common household fabrics used in homemade masks in blocking droplets generated by coughing and sneezing, and have found that they are considerably protective even as a single layer.

Scientists, including one of Indian-origin, have developed a prototype of a rapid COVID-19 test using a simple-to-use portable instrument for reading the results with a smartphone in 30 minutes, an innovation that may enable point-of-care diagnosis without needing to send samples to a lab.

 N95 masks may be the most effective at reducing the spread of the novel coronavirus, according to a study by researchers, including those from the Indian Space Research Organisation (ISRO), which suggests that any mask is better than no mask at preventing COVID-19.

AstroSat, India's first multi- wavelength satellite, has detected an extreme ultraviolet (UV) light from a galaxy which is 9.3 billion light-years away from Earth, the Inter-University Centre for Astronomy and Astrophysics (IUCAA) said on Monday.

A low-cost saliva test that will enable people to collect their own samples with minimal discomfort, without invasive nasal or throat swabs, could well be the way forward to detect the novel coronavirus, say scientists.
