Face shields offer least amount of protection

Based on current evidence, face shields offer the least amount of protection from the spread of SARS-CoV-2 – the coronavirus that causes COVID-19. How so? Well, because physics!

It cannot be stressed enough, COVID-19 is airborne – it is mainly transmitted via aerosols that float in the air which can get around face shields. If you’re not wearing a mask, a face shield is useless and even gives you a false sense of security. Listen to the science: face shields alone will not protect you from COVID-19.

If you’re still not convinced, watch the video below to see how virus-carrying aerosols get around face shields and spread in the air:

So please, do everyone a favor by wearing mask – surgical masks are better if you can’t or don’t want to wear an N95 respirator.

AGHAM – The State of Science & Technology in the Philippines

Was able to join a webinar by Advocates of Science and Technology for the People or AGHAM on The State of Science & Technology in the Philippines and although I had to leave early, it’s an eye-opener not just for science geeks but also for anyone who believes in science.

The COVID-19 pandemic has not only exposed the terrible health care, education and governance of the Philippines, the same could be said of science and technology.

Below is a presentation featured in today’s webinar:

Aside from good governance, good science and technology is badly needed not only if we are to control the COVID-19 pandemic, but also to move the country forward in genuine growth and progress.

Volcano 101: Phreatic eruption in Filipino

Nagiging aktibo ang bulkan kapag ang magma ay umaangat mula sa ilalim ng lupa. Sa pag-angat at pagtama ng magma sa water table o bahagi ng lupa kung saan naipon ang tubig sa loob ng bulkan, lumililkha ito ng steam o water vapor na kumakawala palabas sa bunganga ng bulkan o iba pang biyak sa ibabaw ng lupa.

Sa sobrang bilis ng pagdami ng water vapor, naiipon ito sa loob ng bulkan hanggang sa ito ay sumabog. Sa sobrang lakas ng pagsabog, ang mga bato ay nagiging abo na ibinubuga sa kalangitan. Ang magkahalong steam, abo at maliliit na bato ang siyang dinadala ng hangin sa ibang lugar.

Kung ang bulkan ay magbubuga ng steam at magma ito ay tinatawag na Phreatomagmatic eruption.
