Normal speech by individuals who are asymptomatic but infected with coronavirus may produce enough aerosolized particles to transmit the infection, according to a new study.

Although it’s not yet known how important this is to the spread of COVID-19, it underscores the need for strict social distancing measures, according to the findings, published in the journal Aerosol Science and Technology.


“Aerosols are particles small enough to travel through the air. Ordinary speech creates significant quantities of aerosols from respiratory particles,” said study lead researcher William Ristenpart, Professor at the University of California, Davis in the US.

These respiratory particles are about one micron, or one micrometre, in diameter. That’s too small to see with the naked eye but large enough to carry viruses such as influenza or SARS-CoV-2.

Last year, Ristenpart, graduate student Sima Asadi and colleagues published a paper showing that the louder one speaks, the more particles are emitted and that some individuals are “superemitters” who give off up to 10 times as many particles as others.

The reasons for this are not yet clear.AIn a follow-up study published in January in PLOS One, they investigated which speech sounds are associated with the most particles. Calculating just how easily a virus-like SARS-CoV-2 spreads through droplets requires expertise from different fields, the study said.

From virology, researchers need to know how many viruses are in lung fluids, how easily they form into droplets and how many viruses are needed to start an infection. Aerosol scientists can study how far droplets travel once expelled, how they are affected by air motion in a room and how fast they settle out due to gravity.

“The aerosol science community needs to step up and tackle the current challenge presented by COVID-19, and also help better prepare us for inevitable future pandemics,” the researchers concluded. (IANS)

Between zoom meetings, webinars, you're walking a tight rope to balance work from home and domestic chores, in all this its easy to forget about taking care of yourself. It's imperative to squeeze in a few hours to indulge in yourself, whether its a massage or a hair spa treatment.

It comes with a range of accessories which includes the 40mm Airwrap long barrels, 30mm Airwra barrels, a Firm smoothing brush, a Soft smoothing brush, a Round volumising brush, the Pre-styling dryer, a non-slip heat-resistant mat to place your styler on, a Storage case and even a Filter cleaning brush.

"The discovery of each new world provides a unique glimpse into the physics that play a role in planet formation," said lead author Jon Zink, a UCLA postdoctoral scholar.

An international team of astronomers has identified 366 new exoplanets, using data from the NASA Kepler Space Telescope's K2 mission. The findings, described in a paper published in the Astronomical Journal, showed a planetary system that comprises a star and at least two gas giant planets, each roughly the size of Saturn and located unusually close to one another.

The discovery is significant because it's rare to find gas giants -- like Saturn in the solar system -- as close to their host star as they were in this case. The researchers cannot yet explain why it occurred there, but it makes the finding especially useful because it could help scientists form a more accurate understanding of the parameters for how planets and planetary systems develop.

New moms can follow the given tips to take care of their little ones and protect them from the harmful effects of harsh winds blowing outside.

By Dr Anil Batra

The winter comes with its own set of hassles. New moms have to be careful because they have to take care of themselves and their babies. It becomes imperative to protect babies from the harsh season. The immune system of newborn babies is developing, which makes them susceptible to respiratory infections. But, you can take preventive measures to keep your child warm and safe. Newborn babies need extra care until their immune system becomes stronger to protect their bodies from the harmful effects of viruses and bacteria that usually become more active in the winter season. A drop in the temperature can aggravate different processes in the body, therefore, moms need to take extra care of newborn babies during winters.

New moms can follow the given tips to take care of their little ones and protect them from the harmful effects of harsh winds blowing outside.
